    The persuasive effects of emotional green packaging claims2019In: British Food Journal, ISSN 0007-070X, E-ISSN 1758-4108, Vol. 121, no 12, p. 3233-3246Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of this paper is to investigate the effects of rational green packaging claims vs emotional green packaging claims on consumers' purchase propensity for organic coffee.

    Design/methodology/approach - Three within-subjects experiment were carried out (N=87, N=245, N=60). The experimental design encompasses packaging with rational green claims, emotional green claims, as well as a neutral (control) claim. Measured variables are introduced to assess participants' environmental commitment and information processing ability. A manipulated between-subjects variable is introduced to test how distraction interacts with preference for the claims.

    Findings - Overall, consumers prefer products with green claims over those with neutral (control) claims, and products with emotional green claims to those with rational green claims. The studies also reveal that this effect is moderated by participants' environmental commitment, information processing ability and by distraction. The findings were statistically significant (p<0.05).

    Research limitations/implications - As a lab experiment, the study provides limited generalizability and external validity. Practical implications - For most organic FMCG products, it is advisable to employ emotional packaging claims.

    Social implications - The presented findings provide marketers with tools to influence consumer behavior toward sustainable choices.

    Originality/value - The paper validates previous contributions on the effects of product claim types, and extends them by introducing comprehensive empirical data on all the Elaboration Likelihood Model's criteria for rational decision-making; motivation, opportunity and ability.

    Shedding a light on phototherapy studies with people having dementia: A critical review of the methodology from a light perspective2016In: American Journal of Alzheimer’s Disease and Other Dementia, ISSN 1533-3175, E-ISSN 1938-2731, Vol. 31, no 7, p. 551-563Article in journal (Refereed)
    Abstract [en]

    Light therapy is applied to older people with dementia as a treatment to reset the biological clock, to improve the cognitive functioning, and to reduce behavioral symptoms. Although the methodological quality of light therapy studies is essential, many aspects concerning the description of the lighting applied are missing. This study reviewed light therapy studies concerning the effects on people with dementia as a way to check the methodological quality of the description of light from a light engineering perspective. Twelve studies meeting the inclusion criteria were chosen for further analysis. Each study was scored on a list of aspects relevant to a proper description of lighting aspects. The overview demonstrates that the overall quality of the methodologies is poor. The studies describe the lighting insufficiently and not in the correct metrics. The robustness of light therapy studies can be improved by involving a light engineer or specialist.

    Dynamic lighting systems in psychogeriatric care facilities in the Netherlands: A quantitative and qualitative analysis of stakeholders’ responses and applied technology2015In: Indoor + Built Environment, ISSN 1420-326X, E-ISSN 1423-0070, Vol. 24, no 5, p. 617-630Article in journal (Refereed)
    Abstract [en]

    Long-term care facilities are currently installing dynamic lighting systems with the aim to improve the well-being and behaviour of residents with dementia. The aim of this study was to investigate the implementation of dynamic lighting systems from the perspective of stakeholders and the performance of the technology. Therefore, a questionnaire survey was conducted with the management and care professionals of six care facilities. Moreover, light measurements were conducted in order to describe the exposure of residents to lighting. The results showed that the main reason for purchasing dynamic lighting systems lied in the assumption that the well-being and day/night rhythmicity of residents could be improved. The majority of care professionals were not aware of the reasons why dynamic lighting systems were installed. Despite positive subjective ratings of the dynamic lighting systems, no data were collected by the organizations to evaluate the effectiveness of the lighting. Although the care professionals stated that they did not see any large positive effects of the dynamic lighting systems on the residents and their own work situation, the majority appreciated the dynamic lighting systems more than the old situation. The light values measured in the care facilities did not exceed the minimum threshold values reported in the literature. Therefore, it seems illogical that the dynamic lighting systems installed in the researched care facilities will have any positive health effects.

    Performance of personally worn dosimeters to study non-image forming effects of light: Assessment methods2017In: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 117, p. 60-72Article in journal (Refereed)
    Abstract [en]

    When determining the effects of light on human beings, it is essential to correctly measure the effects, and to correctly measure the adequate properties of light. Therefore, it is important to know what is being measured and know the quality of the measurement devices. This paper describes simple methods for identifying three quality indices; the directional response index, the linearity index and the temperature index. These indices are also checked for several commonly used portable light measurement devices. The results stresses what was already assumed, the quality and the outcome of these devices under different circumstances were very different. Also, the location were these devices are normally worn has an impact on the results. The deviation range between worn vertically at eye level and the wrist is between 11% (outdoor) to 27% (indoor). The smallest deviation, both in indoor and outdoor, was found when the device was placed on the sides of the eye (7%).

    Den juridiska statusen för 3D-modeller som bygghandlingar2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction – This thesis in Building Engineering at Jönköping University, in collaboration with Tyréns Sweden AB, examines the issues surrounding 3D models as construction documents from a legal perspective and investigates how digitization affects stakeholders in the construction industry. The goal of the study is to explore a relevant and interesting research area in order to contribute to knowledge development and the advancement of new theories or methods in the field.

    Method – The study will employ qualitative research, including primary data collection through interviews, to address the research questions posed in the report. The authors have chosen this method to achieve a comprehensive understanding of the respondents' perspectives and identify important themes and patterns. The interviews were conducted with participants from various sectors of the construction industry to obtain a broader picture of the subject.

    Results – The study revealed that there are certain legal barriers to the use of 3D models as drawing documentation. These barriers are related to a lack of knowledge and uncertainty in handling the models. This includes issues of copyright, liability, and evidential value. There is a need to update current regulations to facilitate the management of digital models.

    Analysis – The analysis of the results clarifies that industry standards and clearer guidelines would prevent uncertainties and address knowledge gaps in the use of BIM and 3D models. An industry standard could have facilitated a smoother transition to a more digitized construction industry. There is also a need for education in the field for professionals and decision-making stakeholders.

    Discussion – The discussion focuses on possible solutions to the identified problems, such as the development of standards and guidelines, education, and regulatory updates. There is also a need to raise awareness about the legal aspects of using 3D models in the construction industry, as the uncertainty regarding their legal status is high. Legally, it is possible to use 3D models as contractual documents, but the study shows that concerns about the legal aspects are a reason for the weak implementation.

    Keywords – 3D model, 3D design, BIM, Building Information Modeling, construction documents, contractual law, and copyright.

    Identifying Challenges Regarding Sustainability and Circularity in Foundries: A multiple-case study of OEMs and SMEs in the Swedish foundry industry2023Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of the thesis is to identify Swedish foundries’ challenges regarding circularity and sustainability demands and explore how SME foundries can be more sustainable and circular.

    Method: The research approach used in this study is an exploratory multiple-case study. The research questions are answered by using qualitative data through interviews and observations as data collection methods.

    Findings: The study’s findings present many challenges for Swedish foundries. The main challenges identified are fluctuations in demand, Just-in-Time, extra transports, and the availability of suitable supply chain partners.

    The challenge of demand fluctuations for SME foundries resulted in a recommendation on how SMEs can face the challenge. The recommendation aims to reallocate capacity by warehousing, followed by increasing communication in the supply chain. The study concludes that Swedish foundries are far from achieving circular supply chains but strive for sustainable foundries.

    Practical Implications: Organizations could use this thesis as a point of reference to compare and reflect on their foundry operations. Since SMEs are targeted for facing challenges in the industry, practical implications could provide a recommendation for organizations and managers in the foundry industry to collaborate more efficiently with OEMs.

    Theoretical Implications: This study contributes to the existing knowledge with a new perspective as the challenges connected to sustainability and circularity have been a gap for academia in the foundry industry.

    Delimitations: This thesis delimitates within the supply chain of one SME and two OEMs in the Swedish foundry industry. The SME’s role in the supply chain is a supplier of casted components, while the OEMs are both a producer of castings and a customer of components. The areas within the supply chain studied are castings, materials, logistics, production, and sustainability & circularity.

    Implementering av det biofila fenomen i utformningen av skolbyggnader2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Today, humanity is trying to develop in all areas of life, so that we can reach a cleaner, more modern, and more sustainable world. This study highlights the importance of architecture to improve areas of life. This report talks about a type of architectural design. It is called biophilic design which means to combine nature with buildings. This study is about biophilic design in school buildings.

    Method: To perform the survey, three different methods were chosen. The first method was a questionnaire sent to college students and high school students, the second method was interviews conducted with knowledgeable architects who have extensive experience in the subject of biophilic design and the last method was literature studies.

    Results: All data collected from the questionnaire, the interviews and literature studies are summarized as follows:Most college students and high school students think that when you are closer to nature it makes you feel better and that it would help improve the teaching process. Architects who were interviewed thought that biophilic design in school buildings has both advantages and disadvantages, but in general they support the idea of using and spreading the idea more in Sweden.

    Analysis: The analyzed data have shown that it is possible to implement biophilic design on the inside and outside of a school building in unusual ways. But many problems will arise, and one must have the will to continue to maintain these materials. It turned out that having these natural elements in school will contribute to a positive effect on the learning environment and the students themselves. For example, as a more creative, calm, and de-stressing environment. Having a green roof seems like an innovative idea but it requires a lot of maintenance.

    Discussion: This study focuses on how to implement biophilic design in a school building and what impact it has on the learning environment. The study addressed what is required to integrate the qualities of nature in the right way to maximize its effects. Studying biophilic design, nature and how it affects people and architecture and its impact on people has helped to lead to a clear result.

    En studie i användning av BIM i förstudie och bygglovsprocessen inom kommunal verksamhet2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract 

    Introduction: The construction industry is a large industry and like all other industries, it must always develop. The development can involve several factors, but within today's construction industry, Building Information Modeling (BIM) is a central part of the development. Companies and organizations in Sweden have shown for a long time that there are shortcomings in BIM and its use compared to other countries. There are several reasons for this, but above all the high costs and lack of knowledge about BIM. BIM can facilitate and streamline the construction process and it is something that is not fully utilized, which can make the process slower and less efficient. Communication is a big part of BIM as it facilitates communication, which is one of the biggest problems in the construction industry.Method: The method used to present the theories in the study is semi-structured interviews so that the interviewee has the freedom to design their answers. As well as literature implementation from theoretical frameworks that have been the main data collection method.Results: What the study showed after the conducted interviews and the implementation of literature is that there is a lack of BIM use and digital tools. The shortage exists at different levels in the different municipalities and differs even if the municipalities are roughly the same size when it comes to area and population. Some municipalities have taken the first step towards digitization and have succeeded in that step.Analysis: BIM is a tool that can make it easier for municipalities and companies to work. If they use BIM, it can save time, money and resources. the municipalities know about this and want to use BIM in their work system, but they encounter some problems. They have a lack of trained staff and the economy right now makes it difficult to carry out the process.Discussion: The study shows that BIM is used too little within the municipalityaccording to interviews and literature review. Introducing BIM is expected to make work easier for municipalities, but there are challenges for organizations that want to use BIM and participate in technology development.Keywords: BIM, BIM implementation, Pros and cons of BIM, Preliminary study, Client, digitization within municipal operations and digitization of the building permit process.

    Effektivisering av en produktionsprocess: En fallstudie på Corroventa AB2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A major concern for companies today is the necessity to manufacture a wide range of products with short lead times and at a low cost. This puts greater demands on companies to have a good product mix and volume flexibility while maintaining a high level of efficiency. In addition, companies need to be aware of the source of unknown losses in their organisation and production process in order to minimise them.  This study was conducted at Corroventa avfuktning AB in Bankeryd, Sweden, a company that specialises in products that are used to dehumidify buildings and neutralise radon radiation. Their production process mainly focuses on maintaining stock levels, but adverse weather conditions that cause flooding and water damage could push demand levels to a point where they are unable to guarantee a short enough lead time to win a customer order. This puts pressure on them to make their production process more flexible and efficient while reducing their lead time.  The case study was carried out in a pre-assembly department for the final assembly of adsorption dehumidifiers. The department had been identified as a bottleneck for the whole system during high demand, and the study was undertaken to identify the underlying problem. With a firm theoretical framework and in-depth status analysis the authors identified key areas to improve the overall performance of the pre-assembly department. The improvements included a new production layout, a more balanced assembly process and a reduction in material handling. This led to improved product mix and volume flexibility, and reduced lead times. As a final step, a discussion and conclusion has been written that discusses the validity and reliability of the study, sums up all the areas of improvement and determines further studies that need to be undertaken in order to facilitate future improvements throughout the plant.

    Developing a line balancing tool for reconfigurable manufacturing systems: A tool to support investment decisions2021Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Purpose - This thesis aims to developing a decision-making tool which fits in a reconfigurable manufacturing system (RMS) milieu used to identify whether to introduce and produce a new product into an already existing assembly line or to invest in a new assembly line. To fulfil the purpose, four research questions were developed. 

    1. Which line balancing problem-solving techniques exist in the literature?
    2. Which investment costs can be considered vital for new assembly lines as a    consequence from new product introductions?
    3. Can a decision-making tool be designed to evaluate new product introductions which considers both line balancing KPIs and investment costs in an assembly line?
    4. To what extent can criteria in the RMS theory be linked with the attributes of the    designed decision-making tool to support its applicability?

    Method - Literature studies were performed in order to create a theoretical foundation for the thesis to stand upon, hence enabling the possibility to answer the research questions. The literature studies were structured to focus on selected topics, including reconfigurable manufacturing systems, line balancing, and assembly line investment costs. To answer the third research question, which involved creating a decision-making tool, a single-case study was carried out. The company chosen was within the automotive industry. Data was collected through interviews, document studies and a focus group.

    Findings & analysis - An investigation regarding which line balancing solving-techniques suit RMS and which assembly line investment costs are critical when  introducing new products has been made. The outputs from these  investigations set the foundation for developing a decision-making tool which enables fact-based decisions. To test the decision-making tool’s compatibility with reconfigurable manufacturing systems, an evaluation against established characteristics was performed. The evaluation identified two reconfigurable manufacturing system characteristic as having a direct correlation to the decision-making tool. These characteristics regarded scalability and convertibility.

    Conclusions - The industrial contribution of the thesis was a decision-making tool that enables fact-based decisions regarding whether to introduce a new product into an already existing assembly line or invest in a new assembly line. The academic contribution involved that the procedure for evaluating the tool was recognized as also being suitable for testing the reconfigurable correlation with other production development tools. Another contribution regards bridging the knowledge gaps of the classifications in line balancing-solving techniques and assembly line investment costs.

    Delimitations - One of the delimitations in the thesis involved solely focusing on developing and analysing a decision-making tool from an RMS perspective. Hence, other production systems were not in focus. Also, the thesis only covered the development of a decision-making tool for straight assembly lines, not U-shaped lines.

    Learning through digital apps: An empirical study on gamification and its practical applications in learning environments2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Gamification, that is the use of game mechanics and experience design to engage and motivate people to achieve their goals, has seen an increase in the rate of adoption in several fields including health, marketing, education, crowd-sourcing and others. It is undeniable that the widespread use of new technologies, such as mobile phones, internet, digital applications and social networks added new ways for learning and gaining knowledge. Although the educational field is one of the growingly interesting topics about gamification, there are not enough existing researches on adopting gamification in digital learning apps which are considered nowadays as a convenient tool for many people which aims to enhance the learning process. Digital learning applications are designed for many different purposes to improve many kinds of skills such as music, scientific materials, languages and others. Although increasing technological advancements over the last few years especially in the software world and various forms have been introduced to increase student’s engagement using gamification such as digital learning apps, there is still criticism of how to apply it and there is a need to investigate that in depth. The main purpose of this research is to serve as infrastructure to identify and investigate the core game mechanics / gamification elements which are used in digital learning apps and make it more effective for knowledge acquisition. With a view to examining game mechanics, its impact and consequences, the following research questions have been formed: RQ1: What gamification mechanics are more central to improving the learning process using digital apps? RQ2: What evidence do we have for 1? Do these gamification mechanics also improve the user experience? In order to attempt answering the research questions a list over gamification elements was created by analyzing two chosen games which became later the base for field trial sessions. Data from field trial session was collected with several participants and analyzed before being used in a discussion with the previous theoretical works. The conclusion of the research suggests a group of game elements which have positively affected the learning outcomes when applied in digital apps for learning purpose. Moreover, those elements revolve around achieving at least one of the three core aims, (1) increase level of entertainment and fun, (2) motivate students, and (3) enhance skills to gain learning content. However, further research is required to test more game mechanics and investigate its role and effectiveness when applied in learning apps with a larger number of participants.

    Abstract [en]

    This projects aims to develop design automation in product development. Design automation causes increase in producibility and decrease in product cost and manufacturing lead time.

    The study at hand is proposed to provide a new method and to introduce procedure to the design of wiring pattern for a car seat heater for Kongsberg Automotive, KA. KA is a Norwegian company and a global provider of engineering, design, and manufacture for seat comfort, driver and motion control systems, fluid assemblies, and industrial driver interface products. The method that currently is used in the company to create a wiring pattern is neither sufficient enough nor automated.

    In order to design the wiring pattern, at first procedure is handled by the designer. Secondly, car seat heater 2D layout is imported and then, the dimensions of the elements are defined as constraints. Then VBA codes are opened and the program is run. The result will be a wiring pattern in different 2D layouts. To make the design process easier, we have modeled five different layouts; wiring pattern of one element, two elements, three elements, five elements (with two back sides) and one element trapezoidal 2D layout.

    The algorithm written in VBA (Visual basic for application) creates the pattern according to the dimensions of the elements which are used as inputs to define constrained parameters. The created macros are simple to use and easy to modify, independent from the programming knowledge. The user is only responsible with parameter input and running the program. The solution gives wiring pattern for a car seat heater.

    Evaluations of Product Data Template initiatives2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The AEC (Architecture, Engineering, and Construction) industry has been undergoing a significant digitaliza-tion process in the last years. This transformation implies new challenges and adaptation concerning the ex-change of data between different software applications. Therefore, in response to this problem the benefits of IFC as a solution for the exchange of data have been investigated. However, the current versions of IFC cannot achieve semantic clarity in mapping entities and relationships. Therefore, there have been several attempts to develop solutions and optimizing methods to improve the exchange of information of product data. This paper aims to identify and investigate the challenges of using product data templates (PDT) for exchange of infor-mation and different PDT has been evaluated and compared. The necessary data was collected through literature review and document analysis. Five challenges and five initiatives were identified during the literature review. The five initiatives are Semantic web and linked data, CoClass, Buildingsmart, COBie and Cobuilder. The result showed how these initiatives could solve the identified challenges.

    Study on Compositionality of Terms in Biomedical Events Ontologies2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    An ontology is an explicit specification of conceptualization which intended to capture and formalize the domain knowledge. The ontologies that formalize knowledge about life sciences are biomedical ontologies. The biomedical ontologies are consisted of concepts (are central units of description) which are used for unambiguous and consistent naming of biomedical data and events. The events refer the tasks, providing descriptions of actions among one or more entities in biomedical domain.

     

    The purpose of study is to understand how the terms are composed in biomedical event ontologies. What are the term patterns exist between biomedical terms? How to represent these term patterns? How to categorize according to part-of-speech? The most important is the identification of primary and secondary events in biomedical event ontology terms and their location in biomedical terms patters.

     

    The proposed method produces Finite State Machine explained in the results chapter 4. The FSM identify the primary event e.g. last token of biomedical term and secondary event is immediately followed by preposition in biomedical term. The FSM is a computation model which is used to design for computer programs. FSM is an abstract machine which can be easily programmed and thus is a step towards automatic event extraction which will further lead us to develop the domain specific application, e.g. semantic search, event database curation support, event extraction and event annotations.

     

    For our study, we selected Gene Ontology (GO). The GO provides ontologies of gene products in three separate domains (i) Cellular components (ii) Molecular functions (iii) Biomedical process for our thesis we have selected biomedical process. For the compositional and structural analysis, a biomedical term is broken down into words, and each word is called as “token”. This process is called tokenization of terms. The tokens are categorized according to natural language grammar such as noun, adjectives, preposition, relational adjectives, etc.

    After categorization of tokens on the basis of POS tagging, and the conversion into abbreviation form the resulting form is called as a biomedical term pattern. After collecting the sample of biomedical term patterns we generalized these term patterns and built Finite State Machines.

     

    The research proposed Finite State Machine which provide abstract and concise view of the structure and composition of biomedical terms in biomedical event ontologies. Finite State Machine helps in identification of biomedical events (primary and secondary) in biomedical terms and their possible locations. These Finite State Machines can be used to build computer programs. The computer program will help in building domain specific application e.g. biomedical event corpus, annotation for biomedical event terms, etc.

     

    The results (and evaluation of results) represent that FSMs are the generalized solution to explain the structure of biomedical terms, can identify the events and their locations in biomedical event ontologies.

    Trend analysis to automatically identify heat program changes2017In: Energy Procedia, Elsevier, 2017, p. 407-415Conference paper (Refereed)
    Abstract [en]

    The aim of this study is to improve the monitoring and controlling of heating systems located at customer buildings through the use of a decision support system. To achieve this, the proposed system applies a two-step classifier to detect manual changes of the temperature of the heating system. We apply data from the Swedish company NODA, active in energy optimization and services for energy efficiency, to train and test the suggested system. The decision support system is evaluated through an experiment and the results are validated by experts at NODA. The results show that the decision support system can detect changes within three days after their occurrence and only by considering daily average measurements.

    Stadsutveckling i mellanstora städer: En studie om förtätning i centrala Norrköping ur ett socialt och ekologiskt perspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Planners in Norrköping municipality today facing a challenge to meet Norrköping'sneeds in the housing market, while at the same time achieving demand for public places and areas such as parks, squares and nature areas. When existing areas within the city's borders are built, so-called densification takes place in the city, whichcan have both positive and negative consequences. The aim of this study is to investigatehow the densification has affected Norrköping's inner city from a social and ecologicalperspective with a focus on free space, and present proposals for measures forbetter management of the densification in central Norrköping.

    This study has mainly been carried out using a qualitative research method.A qualitative study is based on soft data such as interviews, document analysis and literature studies. The interviews have been conducted with respondents from Norrköpings municipality and the document analysis consists of steering documents obtained from Norrköpings municipality and Pontarius AB. Some data is obtained from documents and studies where results are presented in the form of tables, diagrams, figures and GIS analysis, which means that quantitative methods are also applied.

    To perform a safer densification, it is important that the municipality establishes safe guidelines and steering documents to relate to. These control documents should be used as a framework for efficient exploitation and ensure that the city's freeareas are developed from a sustainable perspective and that a good quality is includedin the development.

    It is advantageous that the development of the densification takes placeaccording to guidelines and documentation prepared by the municipality. To ensure maximum efficiency in exploitation, these guidelines should be followed at an early stage. It is also important that there is a balance of free space size and their quality. Too small a surface leads to a higher load and larger surfaces can be perceived as superfluousand a feeling of unsecure. It is recommended to study how the densification developsin connection with the infrastructure and how it will affect free and green areas in the long run.

    This study is limited to only the inner city of Norrköping. The study also delimits economic and political factors that can influence the planning of the densification and the development of the city’s infrastructure and public transport.

    Energy security and competition over energy resources in Iran and Caucasus region2017In: AIMS Energy, ISSN 2333-8326, E-ISSN 2333-8334, Vol. 5, no 2, p. 224-238Article in journal (Refereed)
    Abstract [en]

    Energy security as a dominant factor in international stability is of great importance for major economies. The global energy market with its current level of supply and demand relies on energy sources in the Middle East, Caucasus, Central Asia and Russia. After the Fukushima disaster nuclear powers in Europe view renewable energy sources as a serious alternative. Europe’s energy vulnerability has deteriorated due to the Russia-Ukraine conflict. However, renewable energy sources are not large enough to replace nuclear power completely. This trend will continue with climbing demand especially in the natural gas sector as clean energy. In this research, Caucasus and Iran are considered the main sources and routes for energy transmission to the global market, including Europe. Caucasus plays a key role in bridging Europe and Asia. Also, Iran is an alternative for energy transmission to Europe after lifted sanctions. As part of the European active supply diversification policy Iran has capacity to reduce Europe’s energy dependency on Russia. However, changes in US new administration America First Policy is harmful for the EUs energy security. Caucasus aims to catch a large share of the European energy market since the Baku-Tbilisi-Ceyhan pipeline has started operations and Iran is also trying to expand its market to become a sustainable source of energy for major consumers. Therefore, Iran and Caucasus are considered reliable energy suppliers for Europe. In this regard, we analyze the best motivation for changing the direction new suppliers’ energy policies towards Europe and suggest alternative solutions to compete with rival countries in order to enhance energy security.

    Inkorporering av logistik i byggprojektering: För effektivare materialhantering i byggproduktion2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte – Studien avser att undersöka hur inkorporering av logistik i byggprojektering kan effektivisera materialhanteringen i byggproduktion som bedrivs av SME. För att uppnå syftet kommer frågeställningarna nedan besvaras:Hur uppstår slöserier vid materialhantering i byggproduktion?Hur kan inkorporering av logistik i byggprojektering minimera slöserier i byggproduktion?

    Metod – För att uppnå studiens syfte har en fallstudie genomförts på ett specifikt byggprojekt där byggentreprenören är ett SME. Datainsamlingen har skett genom en fallstudie där datainsamlingstekniker som intervjuer, observationer och dokumentstudier har använts. Den insamlade empirin har analyserats mot studiens referensram för att uppfylla studiens syfte.

    Resultat – Inledningsvis identifierades icke värdeskapande aktiviteter i byggproduktionens materialhantering. De slöserier som identifierades är väntan, lager, överarbete, rörelse, omarbete samt medarbetarnas outnyttjade kreativitet. Utifrån framtagen empiri, litteratur och diskussion mellan författarna har logistikverktyg tagits fram för att hantera de aktiviteter som inte skapar värde. I studien framkom det att det finns ett bristande logistiktänk i byggprojekt som bedrivs av SME. Det visades vara bristfällig planering av hur material bör hanteras, vilket författarna anser har en negativ påverkan på effektiviteten i byggproduktion. De framtagna logistikverktygen kan skapa möjlighet till effektivare byggproduktion, där effekten anses bli större om de implementeras under byggprojektering.

    Implikationer – Genom att undersöka hur slöserier uppstår kan de förebyggas med föreslagna logistikverktyg under byggprojektering och därmed skapa en effektivare byggproduktion för SME. De teoretiska implikationerna hjälper till att överbygga det forskningsgap som finns kring hur logistik bör inkorporeras i byggprojektering för att effektivisera materialhanteringen, specifikt för SME.

    Metoddiskussion – Studien som genomförts var av enfallsdesign då fallstudien har utförts på ett specifikt byggprojekt. För att ge en ökad grund för diskussion hade fler byggprojekt kunnat studeras inom fallstudien. Detta för att styrka det resultat som framkommit.

    Nyckelord – Byggprojekt, logistik, materialhantering, Lean Construction, SME

    Bullerbegränsande åtgärder för byggnation nära befintlig väg2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: When cities grow at a faster rate, new places are needed to build housing.The municipalities that are growing tends to choose build sites that previously wererejected due to noise pollution. There are requirements from the state that the noise maynot exceed certain values. The requirements originate from the fact that over twomillion swedes are exposed to noise daily. Noise can lead to health problems, in theform of sleep disorders and cardiovascular disease. To reduce health problems noiseinvestigations are made, where suggestions are made in how noise levels can bereduced. The purpose of the work is to provide the reader with knowledge of whichfactors influence noise investigations and the approach to the choice of noise reductionmeasures so that construction can be made closer to trafficked roads.

    Method: The methods used are literature studies, document analysis and interviews.The literature gathered consists of scientific articles. The documents consist of noiseinvestigations conducted by different companies all over Sweden. Persons to interviewwere chosen from the conductors of the noise investigations documents.

    Findings: To answer the report's purpose, three questions were raised. The firstquestion deals with noise-reducing technologies and which technologies are used today.The report found that there are several ways to reduce noise. In the following order, themost frequently used are: silent facade, noise screen, speed reduction, distance betweenhouse and roads, vegetation, road moving and quiet asphalt. The second question of thereport addresses the factors that influence the choice of noise reduction measure. Fromthe literature study, absorption, reflection and reduction were found to be importantfactors. In the document analysis, surroundings, traffic and speed emerged as importantfactors. In the interviews, aesthetics and price emerged as important in the choice ofwhich reducing action should be taken. The third question deals with the question ofhow construction can be made closer to the road. In the result it appears that all of thesolutions mentioned earlier have the ability to reduce noise, but how effective they areand how well they reduce noise varies from case to case. Surroundings and trafficvolume are of great importance.

    Implications: Making use of the technical solutions previously described, results in areduced noise level and there for construction near road can be made possible.Executing a noise investigation at an early stage means that later and more expensivechanges can be avoided, which means that construction can take place sooner. Thereport suggests therefore that noise issues should be considered early in projects. It isalso important to get a solution that everyone can accept.

    Limitations: The report's results are limited to a smaller selection of noiseinvestigations and interviews. More investigations and interviews could hadcontributed to a larger spectrum. The report does only consider noise outdoors and whatopportunities for noise reduction there are.

    Abstract [en]

    Case studies and modeling of logistics systems are the basis for the formulation of the content and structure of a reference model for the organization and management of Value Networks as a higher stage of integrated development of supply chains. The definition of a mathematical model for the balance of the Value Network can reveal the characteristics and principles of organization and management of Value Networks.The instrument obtained enables supply chains to assess their level of development and identify the characteristics that should be developed to reach the concept of Value Network, which is based on knowledge development and environmental integration as supports of the same and its competitive position in the global market.

    Proper integration into the model of environmental factors ensures that Value Networks are inserted into the objectives of promoting sustainable development. The current concept of logistics flow is extended to incorporate within it the exchange of energy, resources and impacts to the environment.

    The research methods used were based on a combination of study and experimentation of cases and the conceptual and mathematical modeling of systems.

    Non-image-forming effects of light: Implications for the design of living and working environments2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night.

    Nowadays, people spend more of their waking day indoors, with less exposure to the natural daylight cycle, relying on artificial lighting which differs to daylight in a number of aspects, including intensity, spectral composition and light exposure pattern.

    In parallel with the technology development that has been mainly driven by energy-saving reasons, it is important to investigate the non-image-forming effects of different properties of the daily and seasonal light exposure.

    The overall aim of the thesis was to identify characteristics of the daily light exposure that are important to support physiological and psychological needs of humans. To achieve this objective a number of research questions were posed concerning daily and seasonal light exposure, seasonal variation in physiological processes and psychological parameters, and evaluation of light exposure with respect to non-image-forming effects. The research questions were investigated in a longitudinal research design with measurements conducted each month during the year at a high latitude with large seasonal variation in day lengths.

    Self-report diaries and instruments for ambulatory- and static measurements were used to examine daily and seasonal light exposure in the working and living environments and for investigating the relationship between different parameters that can be used for evaluating light exposure according to non-image-forming effects of light. Seasonal variation in daily light exposure and regarding the pattern of light exposure was observed. Also, the results indicate a seasonal variation concerning the quality (i.e. spectral composition of the visible radiation) of the exposing light.

    Two biological markers, melatonin and cortisol, were used for investigating seasonal variation in physiological processes relating to the circadian clock. The results showed higher morning melatonin concentrations and peak level of melatonin during the winter although no seasonal change was observed concerning the phase position of the melatonin rhythm.

    Seasonal differences in mood and sleep-activity were studied by means of selfreport diaries and questionnaires. Seasonal variations were observed for both parameters. The results showed higher ratings of mood in the summer, particularly 6 in the evening, and a relationship between bedtime and evening light exposure and photoperiod length. Furthermore, longer sleep times was observed in the winter.

    Appraisal of lighting conditions in the offices during the year was rated by the use of a questionnaire. The results showed some seasonal differences concerning the perceived qualities of the light and some associations between characteristics of the lit environments and positive affect were found.

    Two methods, static- and ambulatory measurements, were used for recording lighting conditions in the working environments. Taken together, the results showed weak associations between the two methods.

    Research have demonstrated an increased need for taking non-image-forming effects into consideration when designing working and living environments, especially at geographical locations with large variations in day length where people are exposed to much of the daily light exposure at the workplace. Laboratory research has provided a good understanding of the basic concepts. However, more field research is needed. Also, current research has demonstrated that new methods of measuring and evaluating lighting conditions are needed.

    Annual variation in daily light exposure and circadian change of melatonin and cortisol concentrations at a northern latitude with large seasonal differences in photoperiod length2016In: Journal of Physiological Anthropology, ISSN 1880-6791, E-ISSN 1880-6805, Vol. 36, no 1Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Seasonal variations in physiology and behavior have frequently been reported. Light is the major zeitgeber for synchronizing internal circadian rhythms with the external solar day. Non-image forming effects of light radiation, for example, phase resetting of the circadian rhythms, melatonin suppression, and acute alerting effects, depend on several characteristics of the light exposure including intensity, timing and duration, spectral composition and previous light exposure, or light history. The aim of the present study was to report on the natural pattern of diurnal and seasonal light exposure and to examine seasonal variations in the circadian change of melatonin and cortisol concentrations for a group of Swedish office workers.

    METHODS: Fifteen subjects participated in a field study that was carried out in the south of Sweden. Ambulatory equipment was used for monthly measurements of the daily exposure to light radiation across the year. The measurements included illuminance and irradiance. The subjects collected saliva samples every 4 h during 1 day of the monthly measuring period.

    RESULTS: The results showed that there were large seasonal differences in daily amount of light exposure across the year. Seasonal differences were observed during the time periods 04:00-08:00, 08:00-12:00, 12:00-16:00, 16:00-20:00, and 20:00-24:00. Moreover, there were seasonal differences regarding the exposure pattern. The subjects were to a larger extent exposed to light in the afternoon/evening in the summer. During the winter, spring, and autumn, the subjects received much of the daily light exposure in the morning and early afternoon. Regarding melatonin, a seasonal variation was observed with a larger peak level during the winter and higher levels in the morning at 07:00.

    CONCLUSIONS: This study adds to the results from other naturalistic studies by reporting on the diurnal and seasonal light exposure patterns for a group living at a northern latitude of 56° N, with large annual variations in photoperiod length. It seems to be seasonal variation in the lighting conditions, both concerning intensities as well as regarding the pattern of the light exposure to which people living at high latitudes are exposed which may result in seasonal variation in the circadian profile of melatonin.

    Comparison of Static and Ambulatory Measurements of Illuminance and Spectral Composition That Can Be Used for Assessing Light Exposure in Real Working Environments2019In: LEUKOS The Journal of the Illuminating Engineering Society of North America, ISSN 1550-2724, E-ISSN 1550-2716, Vol. 15, no 2-3, p. 181-194Article in journal (Refereed)
    Abstract [en]

    Reliable measurements are of utmost importance when investigating the relationship between light and human reactions. The aim of the present study was to compare two methods for measuring light exposure in real working environments. Ambulatory recordings of illuminance and irradiance were compared with static field measurements of horizontal illuminance at the normal working position, average horizontal illuminance in the room, vertical illuminance at the position of the eye in the normal angle of gaze, and spectral composition of the light radiation at the normal working position and at the position of the eye in the normal angle of gaze. The ambulatory measurements were carried out during a 3-day experimental period and were repeated monthly throughout the year. The static field measurements in the subjects’ offices were conducted five times during the year, in the morning and afternoon during one day. The relationship between the illuminances and irradiances measured with the portable instruments and the static measurements was statistically analyzed. Results from the analyses revealed that more than one third of the static measurements of vertical illuminances recorded were below 200 lx, and only 7% of the measurements exceeded 1000 lx. Measurements of the spectral composition of the light radiation in the rooms suggested that the light, although at a fairly low intensity, included relatively much radiation that can have a non-image forming effect. Furthermore, only a small number of significant correlations between the ambulatory and static measurements were found. Results from the t-tests showed that there were no differences between ambulatory measurements, and static measurements of horizontal illuminance at the normal position, average illuminance in the room and vertical illuminance at the position of the eye during three, five, and seven of the 10 measurements, respectively. There is a need to define appropriate parameters in order to describe the quality of a lit environment with respect to the non-image-forming effects of light radiation.

    Seasonal variation in bright daylight exposure, mood and behavior among a group of office workers in Sweden2018In: Journal of Circadian Rhythms, E-ISSN 1740-3391, Vol. 16, article id 2Article in journal (Refereed)
    Abstract [en]

    The purpose of the study was to investigate seasonal variation in mood and behavior among a group of office workers in Sweden (56°N). Thirty subjects participated in this longitudinal study. The subjects kept a weekly log that included questionnaires for ratings of psychological wellbeing and daily sleep-activity diaries where they also noted time spent outdoors. The lighting conditions in the offices were subjectively evaluated during one day, five times over the year. There was a seasonal variation in positive affect and in sleep-activity behavior. Across the year, there was a large variation in the total time spent outdoors in daylight. The subjects reported seasonal variation concerning the pleasantness, variation and strength of the light in the offices and regarding the visibility in the rooms. Finally, the subjects spent most of their time indoors, relying on artificial lighting, which demonstrates the importance of the lighting quality in indoor environments.

    A holistic approach for a natural light variation experience: a pilot study of a practical application for office lighting2019Conference paper (Refereed)
    Abstract [en]

    Lighting is crucial for vision and has important effects beyond vision, influencing a variety of physiological and behavioral processes. When designing lighting, visual aspects, effects beyond vision, and perception of the environment should be considered together in a holistic approach. As humans evolved under daylight, a lighting protocol, based on a room context and daylight characteristics, was developed and described. The lighting, with customized light levels, spectral composition and light distribution that changed dynamically to evoke a perception of daylight conditions, was realized using commercially available luminaires and a digital control system. The resulting lighting conditions are described by measurements.

    Automatic generation of fuzzy inference rules in a reshoring decision context2019In: Proceedings of the 9th International Conference on Operations and Supply Chain Management, Vietnam, 2019, OSCM , 2019Conference paper (Refereed)
    Abstract [en]

    This paper presents a decision-support system for reshoring decision-making based on fuzzy logic. The construction and functionality of the decision-support system is briefly outlined and evaluated in a highcost environment contemplating six specific decision criteria, namely cost, quality, time, flexibility, innovation and sustainability. A major challenge with fuzzy logic solutions has to do with the construction of the fuzzy inference rules. In the relocation domain, the fuzzy inference rules represent the knowledge and competence of relocation experts and they are usually created manually by the same experts. One obstacle is that the complexity of the fuzzy inference rules increases with the number of decision criteria. To overcome this complexity issue, this paper presents a solution whereby the fuzzy inference rules are automatically generated by applying one hundred reshoring scenarios as input data. The reshoring decision recommendations produced by the fuzzy logic decision-support system are demonstrated to be close to those of human reshoring domain experts.

    Semi-Automatic Generation of a Fuzzy Inference System in a Reshoring Context2020In: SPS2020: Proceedings of the Swedish Production Symposium, October 7–8, 2020 / [ed] K. Säfsten & F. Elgh, IOS Press, 2020, Vol. 13, p. 599-609Conference paper (Refereed)
    Abstract [en]

    Reshoring can be regarded as offshoring in reverse. While offshoring mainly has been driven by cost aspects, reshoring considers multiple aspects, such as higher quality demands, faster product delivery and product mass-customization. Where to locate manufacturing is usually a purely manual activity that relies on relocation experts, hence, an automated decision-support system would be extremely useful. This paper presents a decision-support system for reshoring decision-making building a fuzzy inference system. The construction and functionality of the fuzzy inference system is briefly outlined and evaluated within a high-cost environment considering six specific reshoring decision criteria, namely cost, quality, time, flexibility, innovation and sustainability. A challenge in fuzzy logic relates to the construction of the so called fuzzy inference rules. In the relocation domain, fuzzy inference rules represent the knowledge and competence of relocation experts and are usually generated manually by the same experts. This paper presents a solution where fuzzy inference rules are automatically generated applying one hundred reshoring scenarios as input data. Another important aspect in fuzzy logic relates to the membership functions. These are mostly manually defined but, in this paper, a semi-Automatic approach is presented. The reshoring decision recommendations produced by the semi-Automatically configured fuzzy inference system are shown to be as accurate as those of a manually configured fuzzy inference system.

    Test case quality as perceived in Sweden2018In: Proceedings - International Conference on Software Engineering / [ed] Michael Unterkalmsteiner, ACM Digital Library, 2018, p. 9-12Conference paper (Refereed)
    Abstract [en]

    In order to reach an acceptable level of confidence in the quality of a software product, testing of the software is paramount. To obtain "good" quality software it is essential to rely on "good" test cases. To define the criteria for what make up for a "good" test case is not a trivial task. Over the past 15 years, a short list of publications have presented criteria for "good" test cases but without ranking them based on their importance. This paper presents a non-exhaustive and non-authoritative tentative list of 15 criteria and a ranking of their relative importance. A number of the criteria come from previous publications but also from discussions with our industrial partners. The ranking is based on results collected via a questionnaire that was sent out to a limited number of randomly chosen respondents in the Swedish software industry. This means that the results are more indicative than conclusive.

    Investigation of residual stresses generation in aluminum flywheel2009Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Quality of the castings is affected by several factors which the designer should take into consideration during the product development process. Although residual stress is one of those, it is often not considered in practical computations. Hence residual stresses are one of the forgotten areas in designing of machine parts. This master thesis is focused on the investigation of residual stresses in a high pressure die casted component, with the aim of extending its service life, by taking results from the study as a feedback.

    The investigation of residual stresses was done on a variety of specimens, cast aluminum flywheel, provided by Husqvarna AB. This flywheel is a component in a product of the same company.In evaluating the residual stresses in the part, two tools-simulation and physical measurement were used. Moreover, comparison with these two methods is also done at an area of interest on the flywheel. The simulation was carried out by using MAGMAhpdc-a module for high pressure die casting process, from the commercial software package MAGMAsoft; while for the physical measurements, the hole drilling method was used, a method believed to be less accurate at low stresses areas.

    The findings obtained from this study show that the results from both procedures are close, with small deviations observed, which reveals the reliability of the hole drilling method even when the stress levels are low. It is also found that the compressive residual stresses dominate in the component-a preferred phenomenon with regards to residual stress.

    Graph-Based Visualization of Ontology-Based Competence Profiles for Research Collaboration2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Information visualization can be valuable in a wide range of applications, it deals with abstract, non-spatial data and with the representation of data elements in a meaningful form irrespective of the size of the data, because sometimes visualization itself focuses on the certain key aspects of the data in the representation and thus it helps by providing ease for the goal oriented interpretation. Information visualization focuses on providing a spontaneous and deeper level of the understanding of the data.

    Research collaboration enhances sharing knowledge and also enhances an individual’s talent. New ideas are generated when knowledge is shared and transferred among each other. According to (He et al, 2009) Research collaboration has been considered as a phenomenon of growing importance for the researchers, also it should be encouraged and is considered to be a “good thing” among the researchers.

    The main purpose of this thesis work is to prepare a model for the competence profile visualization purpose. For this purpose the study of different visualization techniques that exist in the field of information visualization are discussed in this thesis work. The study and discussion about the visualization techniques motivates in selecting appropriate visualization techniques for the visualization of Ontology-based competence profiles for research collaboration purpose. A proof of concept is developed which shows how these visualization techniques are applied to visualize several components of competence profile.

    Bioinstructive implantable scaffolds for rapid in vivo manufacture and release of CAR-T cells2022In: Nature Biotechnology, ISSN 1087-0156, E-ISSN 1546-1696, Vol. 40, no 8, p. 1250-1258Article in journal (Refereed)
    Abstract [en]

    Despite their clinical success, chimeric antigen receptor (CAR)-T cell therapies for B cell malignancies are limited by lengthy, costly and labor-intensive ex vivo manufacturing procedures that might lead to cell products with heterogeneous composition. Here we describe an implantable Multifunctional Alginate Scaffold for T Cell Engineering and Release (MASTER) that streamlines in vivo CAR-T cell manufacturing and reduces processing time to a single day. When seeded with human peripheral blood mononuclear cells and CD19-encoding retroviral particles, MASTER provides the appropriate interface for viral vector-mediated gene transfer and, after subcutaneous implantation, mediates the release of functional CAR-T cells in mice. We further demonstrate that in vivo-generated CAR-T cells enter the bloodstream and control distal tumor growth in a mouse xenograft model of lymphoma, showing greater persistence than conventional CAR-T cells. MASTER promises to transform CAR-T cell therapy by fast-tracking manufacture and potentially reducing the complexity and resources needed for provision of this type of therapy.

    PREFABRICERADE SMÅHUS PLANLÖSNINGAR: En jämförelse mellan tillverkare och kund2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med arbetet är att analysera utformningen av planlösningarna i prefabricerade småhus. Resultatet ska kunna utnyttjas som underlag vid planlösningsutformning och möjliggöra planlösningar med färre kundändringar.  

    Metoder som används är litteraturstudier, intervjuer och en fallstudie. Fallstudien är gjord med material från företaget Anebyhus som tillverkar prefabricerade småhus. Ur en av deras kataloger valdes tre olika hus med snarlika förutsättningar. Det som analyseras är tillverkares och kunders prioriteringar samt de vanligaste kundändringarna. Problemet är att om kunden ska bli nöjd med den slutliga planlösningen måste kunden och tillverkaren ha liknande kvalitetsprioriteringar. Ändringar som återkommer frekvent är ett tecken på en svaghet i ursprungsplanlösningen.

    Resultaten visar att tillverkare av prefabricerade småhus möter kundernas behov och önskemål genom prioriteringar av livslångtboende och flexibilitet i planlösningen. Kunderna visar prioritering av mer bänkytor i köket, vardagsrummet storlek och samband till köket och att alla i familjen ska få varsitt sovrum. De kundändringar som förekommer mest frekvent är minskning av antalet klädkammare, sammanslagning av teknik och klädvård samt att ändra till en U-formad köksuppställning.
