    Snabbt förändrade arbetsmiljöer kräver forskning som bidrar till bred kunskap och metodik.2018In: Arbetsmarknad & Arbetsliv, ISSN 1400-9692, Vol. 24, no 3-4, p. 85-89Article in journal (Other academic)
    Abstract [sv]

    I takt med arbetslivets snabba utveckling skapas fler och nya variationer av arbetsmiljöer som kan få helt olika betydelser för grupper på arbetsmarknaden. Inte minst då skillnader mellan grupper ökar. För att arbetsmiljöarbete ska bli verkningsfullt bör vi arbetslivsforskare minska fokus på övergripande medeltal där alla ”dragits över en kam” och istället satsa på mer arbetsplatsnära förhållningssätt om hur arbetsmiljöerna påverkar olika grupper och individer. Arbetslivsforskning behövs som kan ta sig an arbetslivets komplexa förändringar och bidra med bredare kunskaper till aktörerna som bedriver arbetsmiljöarbete – och att vi forskare samverkar med dessa aktörer.

    A complex teamwork intervention in a surgical ward in Norway2019In: BMC Research Notes, ISSN 1756-0500, E-ISSN 1756-0500, Vol. 12, no 1, article id 582Article in journal (Refereed)
    Abstract [en]

    Objectives: Interprofessional team training has a positive impact on team behavior and patient safety culture. The overall objective of the study was to explore the impact of an interprofessional teamwork intervention in a surgical ward on structure, process and outcome. In this paper, the implementation of the teamwork intervention is reported to expand the understanding of the future evaluation results of this study. Results: The evidence-based Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) program was implemented in three phases according to the program's implementation plan, which are built on Kotter's organizational change model. In the first phase, a project group with the leaders and researchers was established and information about the project was given to all health care personnel in the ward. The second phase comprised 6 h interprofessional team training for all frontline health care personnel followed by 12 months implementation of TeamSTEPPS tools and strategies. In the third phase, the implementation of the tools and strategies continued, and refresher training was conducted. Trial registration Trial registration number (TRN) is ISRCTN13997367. The study was registered retrospectively with registration date May 30, 2017

    Collaboration and Satisfaction About Care Decisions in Team questionnaire: Psychometric testing of the Norwegian version, and hospital healthcare personnel perceptions across hospital units2019In: Nursing Open, E-ISSN 2054-1058, Vol. 6, no 2, p. 642-650Article in journal (Refereed)
    Abstract [en]

    Aim To translate "The Collaboration and Satisfaction About Care Decisions in Team" questionnaire (CSACD-T) into Norwegian and test it for psychometric properties. The further aim was to describe and compare healthcare personnel's collaboration and satisfaction about team decision-making (TDM) across hospital units. Design A cross-sectional study. Methods The questionnaire was translated into Norwegian. A total of 247 healthcare personnel at two hospitals responded to the questionnaire. An explorative factor analysis was performed to test the factor structure of the questionnaire, while a Cronbach's alpha analysis was used to test for internal consistency. A one-way ANOVA analysis and a Kruskal-Wallis test were applied to test for differences between hospital units. Results The results demonstrate that the Norwegian version of the CSACD-T has promising psychometric properties regarding construct validity and internal consistency. The mean score of the CSACD-T was significantly higher in the maternity ward group than in the emergency room group.

    Anpassning och differentiering av undervisning i ett klassrum för alla: Strategier för anpassning av undervisning i teori och praktik och dess effekter på elevers delaktighet2015Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    This paper aims to investigate if and how instruction is adjusted or differentiated based on the conception that learners are diverse and how teacher practices are connected to contemporary research in the field. It further examines whether specific adjustments are connected to a higher rate of student participation.

    The method of the essay is an observation survey with a phenomenological approach. It includes the practices of 30 different teachers during thirty lessons at an upper secondary school in Sweden, where the majority of the students are diagnosed within the neuropsychiatric spectra. The outcome was quantitatively analyzed in SPSS.

    The study indicates that the connection between specific adjustments and student participation is a complex issue affected by several aspects and preconditions. It appears that teachers use certain forms of adjustments at a higher rate while some are less salient in instruction. More frequently used adjustments are; praise, providing alternatives for perception, activating previous knowledge and highlighting critical features. Less frequent are differentiation of tasks, visible agendas, formative feedback, collaborative peer-learning and self-assessment.

    This essay will furthermore be a basis for collaborative learning among the staff since a deeper knowledge of how instruction can be adjusted and differentiated will impact the outcome of student learning.

    Arbetslagsledarens uppdrag - distribuerat ledarskap i gymnasieskolan2019Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study explores the formation of the teacher team leaders´ role, using interviews and job descriptions at comprehensive upper secondary schools in a Swedish metropolitan municipality. The theoretical framework includes a social constructionist and critical perspective, through Foucault, based on analysis of power. Analysis of power illuminates contemporary practices and techniques through a historical lens, using questions that are related to the basis and logics of power.

    The job descriptions proclaim a diverse, extensive and somewhat scattered mission consisting of administrative duties as well as managing development and evaluation of processes. According to the job description, the teacher team leader is responsible for initiating learning processes as well as implementing decisions by principals, each advocating a different theory. Teacher team leaders describe a complex mission where a substantial amount of time is spent on tasks less prevalent or unmentioned in the job description. Acting as a messenger, yet a constant search for information and administrative duties are tasks that teacher team leaders emphasize.

    In conclusion, it appears as if a comprehensive view of the mission at hand is deficient and that actual practice appears relatively different from the job description. The teacher team leaders operate as a link between school leaders, the Student Health Team and teachers where they contribute to continuity and stability in a school where school leaders more frequently are exchanged. A new and complex organization involving several distributed leadership roles requires thorough work in terms of co-ordination. Future studies may address how interplay and collaboration can work in a complex organization, where preconditions are continuously altered.

    Innovation in service ecosystems: An empirical study of the integration of values, brands, service systems and experience rooms2016In: Journal of Service Management, ISSN 1757-5818, E-ISSN 1757-5826, Vol. 27, no 4, p. 619-651Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to extend the understanding of innovation in service ecosystems by focussing on the role of values resonance in relation to the integration of brands, service systems and experience rooms.

    Design/methodology/approach – An empirical, explorative case study of an innovative service system is carried out using a narrative approach and presented in the form of a saga.

    Findings – Insights gleaned from the empirical study are used for conceptual developments. Analysis of the empirical case study is presented as four lessons linked to values, brands, service systems and experience rooms.

    Originality/value – The paper extends a conceptual framework of innovative resource integration in service ecosystems. The paper also contributes four propositions to inform theory: values resonance is a basis for service innovation, the innovative integration of brands based on values resonance can foster innovation, the integration of resources across service system boundaries grounded in values resonance can enable innovation and the integration of experience rooms into a coherent servicescape based on values resonance can support novel forms of resource integration and value co-creation efforts in service ecosystems.

    Defense Machanisms in Kauzo Ishiguro’s The Remains of the Day2002Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    In this essay I have examined some of the defense mechanisms which are at play in The Remains of the Day. Defenses are described by Sigmund Freud in his psycho-analytic theory as people´s unconscious ego mechanisms which prevent them from their internal pain but also from the pain of the outside world. People´s unconsciously suppressed pains, fears and wounds cause actions of disguise, distortion and deception, which in turn assert themselves through people´s defenses. People´s defenses protect them from their core issues such as low self-esteem and insecurity about one´s own self. The defenses I examine are denial, fear of intimacy, projection and repression: the defenses which are at play in Mr Stevens´ life. His defenses protect him from revealing his core issues since they cause a great deal of anxiety throughout his life. Moreover, his defenses help him uphold what he sees as ideals of professionalism, dignity and noble moral values. In this essay I have found that the defenses he uses to avoid anxiety are in vain. The more he conceals the more he reveals. In his relation to the significant people in his life - Miss Kenton, his father and Lord Darlington - he reveals his suppressed pains, fears and wounds through his distorted behaviour and his deceptive actions. He looks back and tries to examine his life, but he is not able to acknowledge the anxiety and the discomfort of his painful memories. The consequences of hiding behind his defenses are that he ends up lonely and desolate and with a deep feeling of regret. My conclusion is that when his defenses finally break down it is too late for Mr Stevens. His life had come full circle. He chooses to seek the security of the familiar; in this novel represented by Darlington Hall.

    El agua, la tierra, el aire y el fuego - símbolos de lucha y liberación en Como agua para chocolate2004Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [es]

    Como agua para chocolate (1989) es la primera novela de la escritora mexicana Laura Esquivel.(1950) Esta novela trata, en efecto, de amores, recetas de cocina y una serie de consejos que año tras año se conservan en el seno familiar para resolver problemas cotidianos. Se puede afirmar que el tema principal de la novela, la historia de amor frustrado entre Tita, la protagonista, y Pedro, es presentado como una referencia más entre la enorme cantidad de referencias históricas, sociales y culturales que hay en la novela. En este trabajo, nos proponemos estudiar de qué modo se presenta la lucha entre los diferentes personajes de la novela, especialmente Tita de la Garza, y analizar el proceso de liberación de las normas y reglas de la sociedad mexicana. Intentaremos mostrar cuáles son los elementos que contribuyen a poner de relieve los diferentes conflictos que pueden conducir a la solución o no de los problemas de los personajes en la historia en el texto. De esta forma intentaremos demostrar que la lucha familiar que se da en la historia puede ser interpretada como correlato de la lucha social que sirve de trasfondo histórico: la revolución mexicana. (1910-1917). Tita tiene que enfrentar a su madre y luchar, primero, contra sí misma como persona y como mujer y, después, contra Mamá Elena, su madre, en cuanto es heredera femenina de una tradición social y cultural de carácter patriarcal. Los cuatro elementos, el agua, la tierra, el aire y el fuego desempeñan un papel central en la simbología como principios de organización y se ponen en evidencia a través del texto. En este trabajo seguiremos estos elementos para organizar y desarrollar la lucha y el proceso de liberación de los personajes, en general, y de la protagonista, en particular. Además, vamos a ver si para la protagonista, en el proceso de liberación personal, hay posibilidades de romper con el ciclo de vida repetitivo que estos elementos construyen en su conjunto en la interacción que se da con los personajes secundarios de la novela. De acuerdo con estas suposiciones analizamos y desarrollamos nuestro trabajo.

    Är framtiden agilt för kommuner?: En studie som undersöker hur projekt bedrivs i kommuner och ställer det mot ett agilt arbetssätt.2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    More recently, there has been increased pressure on politically controlled organizations, including municipalities, to become more flexible and find new ways of working. With increased projectification and an increased efficiency as an endeavour for this, it has created organizational tensions in municipal projects. Here, the agile working method in projects has emerged and is seen as a potential solution and a new way of working in projects for a municipal activity.

    The purpose of this study has been to investigate how projects are conducted in a municipal activity and with the issues, how does the agile working method relate to projects at a municipal level and how does the project relate to political governance. In order to be able to answer these, semi-structured interviews were conducted with project managers from different municipalities, with a total of six respondents. The collected material has then been coded through a thematic analysis.

    It is stated that projects carried out in the municipal area need to relate to, among other things, political governance, laws and frameworks. Results also illustrate that there are changes during the course of the projects in municipal projects, which is a burden. The result also indicates that an agile way of working could improve with faster handling of changes in projects. The agile way of working would also work in smaller municipalities because the result indicates that the projects conducted in smaller municipalities are not of the same scope, budget and timeframe, which suits the agile working method.

    Självkörande fordon i stadsrummet?: En studie om självkörande fordons påverkan på individ, mobilitet och planering med fokus på Göteborg Stad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Självkörande bilar betraktas ofta som nästa steg i utvecklingen av bilen och som en del av det autonoma samhället. Bilproducenter världen över menar att vi kan se självkörande fordon så snart som år 2020 och trycker på både forskning och utveckling av självkörande fordon. Beroende på vilken grad av automatisering och hur politiken tillåter självkörande fordon att inträda i samhället, väcker detta frågor som är viktiga att studera. Vem ska äga självkörande fordon? Vilka kommer att köra självkörande fordon? Kommer det att planeras självkörande fordon? Kommer individens rörelsemönster att ändras? I så fall, hur?

     

    I den här studien försöker vi svara på några av dessa frågor genom att undersöka vad bilen inneburit för individens mobilitet i historien och vad självkörande fordon skulle kunna förändra in i framtiden. Vi ställer oss även frågan om självkörande fordon kommer att påverka planeringen av stadsrummet. Studiens teoretiska referensram utgörs av tidigare forskning och teorier som berör mobiliteten, bilismen och planeringen. Metoden är kvalitativ och utgörs av semistrukturerade intervjuer och dokumentstudier. En intervju gjordes med en respondent från Göteborgs Stad och två stycken intervjuer gjordes Trafikverket. Dokumentstudien utgår ifrån VTI, Statens Väg- och Transportforskningsinstitut och SKL, Sveriges Kommuner och Landsting. Alla de olika myndigheterna har en betydelsefull roll i implementeringen av självkörande fordon och intervjuguiden utgår ifrån de teoretiska utgångspunkterna och den tidigare forskningen.    

     

    I studiens slutsats kommer vi fram till att självkörande fordon påverkar planeringen av stadsrummet, men inte i den stora mån vi först trodde. Planeringen av självkörande fordon kan troligtvis främst ske utanför redan etablerade områden och främst när det planeras nytt. Vi kom även fram till att självkörande fordon kan komma att ändra mobiliteteten hos den urbana individen eftersom självkörande fordon har potentialen att erbjuda fler val av rörelse av rörelse och därmed öka tillgängligheten i stadsrummet.

    Environmental issues in Finnish school textbooks on religious education and ethics2013In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2013:1, p. 131-157Article in journal (Refereed)
    Abstract [en]

    Solving global environmental problems requires a major change of values. As relates to environmental education, worldview, ethics and spiritual issues are important elements. But how are environmental issues included in such school subjects that especially discuss values and ethics? In this article I examine 24 Finnish religious education and ethics textbooks to analyze, to what extent environmental issues are integrated and discussed in them. I conclude that there is confusion about what environmental education can be in societal school subjects. The environmental texts in textbooks do not always draw on the specific content of the societal subject in question but repeat content from the natural sciences. Therefore, I suggest contexts and perspectives for discussing environmental issues that would comport with these subjects and supplement existing environmental education at school.

    Possible correlation between sustainability, wellbeing and traditional African values: Wellbeing factors among citizens in Eastern Cape Province, South Africa2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

     Present development path is based on the Western ideas, with focus on market, competition, capitalism and individualism. It has shown to create unsustainable patterns in terms of a growing ecological footprint, decreased wellbeing and growing inequities. This calls for new, alternative development paths. The traditional African values are based on a holistic and humanistic ideology which focuses on health and safety of common citizens; meeting all peoples basic needs, sharing, social connectedness, living in harmony with other species and nature, a healthy environment, to experience satisfaction when your basic needs are met, not wanting more than you need (luxurious cravings), and the concern for health of future generations. In this sense, traditional values are sustainability bearing, and are also suggested to influence human wellbeing in a positive way.   This study have explored to what extent sustainability-bearing values from the traditional African lifestyle are considered to be important for the wellbeing of young, black individuals, and analyzed whether the values of means to achieve wellbeing differs or corresponds between people living a traditionally influenced lifestyle and a Western influenced lifestyle. Generally, the respondents found all these values more important for their wellbeing than luxurious consumption.     This suggests that values that are sustainability bearing are important for peoples wellbeing, and is thereby important to include in the development debate.

    Tänk att de flesta lyckas! - läs- och skrivinlärningsprocesser, metoder och erfarenheter2004Independent thesis Basic level (professional degree)Student thesis
    Abstract [sv]

    Detta arbete handlar om läs- och skrivinlärning, om metoder och förhållningssätt och hur de tillämpas i verksamheten. Syftet med studien är att få kunskaper om läs- och skrivinlärningsmetoder och hur de används i arbetet med eleverna. Jag har gjort litteraturstudier och kvalitativa intervjuer för att besvara mina frågeställningar. Resultatet av undersökningen är således att läsning och skrivning är komplicerade processer som kräver fast struktur med regelbunden uppföljning. En kombination av olika metoder är det bästa för att tillgodose alla elevers behov. En god balans mellan analytisk, syntetisk metod är att föredra. Den socialinteraktionistiska grundsynen är det bästa att utgå från i sin undervisning, vilken belyser vikten av att lära tillsammans i en social miljö. Viktigt för undervisningen är även att utgå från elever och skapa intresse för skriftspråket. Det ska vara roligt att läsa.

    Gymnasieelevers tankar kring studier vid högskola och universitet - en kvalitativ undersökning2002Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Konsumenter väljer oftast de produkter som värderas mest fördelaktigt. Det är därför viktigt för marknadsförare att förstå vilka attityder som ligger bakom människors val. Först då kan de påverka och förändra attityderna, lära sig hur deras strategier fungerar och göra justeringar för att förbättra strategiernas effektivitet. Karlstads universitet arbetar med en profileringskampanj vars mål är att öka antalet förstahandssökande till universitetet. För att genomföra kampanjen krävs information om framförallt potentiella elever från Karlstads universitets främsta upptagningsområden. Genom en attitydundersökning bland dessa gymnasieelever kan Karlstads universitet få kunskaper om elevernas attityder vid val av högskola/universitet. Utifrån denna information kan universitetet ta ställning till den fortsatta profileringen och följaktligen vilka attribut som ska lyftas fram i den kommande marknadsföringen och i kurskatalogen. Syftet med uppsatsen är att undersöka vilka attityder de tillfrågade gymnasieeleverna från karlstads universitets främsta upptagningsområde har till högskola/universitet och den information de får i form av bland annat kurskataloger. Vårt syfte är också att ta reda på vad de tycker är viktigt vid val av högskola eller universitet. Den framkomna informationen analyseras och presenteras både i form av analysmodeller och som löpande text varvat med citat för att understryka viktiga synpunkter. Metoden som används i arbetet är av kvalitativ karaktär, där intervjuer med gymnasieelever har genomförts. Det insamlade datamaterialet har bl.a. analyserats utifrån två analysmodeller. Denna klassificering är uppsatsens kunskapsbidrag. Utifrån vårt syfte har ett antal slutsatser dragits. Det visar sig att våra respondenter har övervägande positiva attityder till högskola och universitet. Det framkommer också att det är utbildningen i sig som främst styr valet av högskola eller universitet men staden som sådan, där högskolan/universitetet ligger, har också stor betydelse. Både den skriftliga och den muntliga informationen från högskola/universitet är gymnasieeleverna negativa till. De efterlyser bl.a. mer information om framtiden, de olika skolornas profiler och staden med omnejd.

    Trött i trafik - en kvalitativ studie om information och kommunikation på uppdrag av Vägverket2003Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    Ett faktum som belysts i media den senaste tiden är att antalet unga i åldern 18-24 år som skadas eller dör i trafiken ökat markant under de senaste åren, stick i stäv med Riksdagens beslut om nollvisionen. Orsakerna bakom dessa olyckor är många, men en faktor som forskare, både i Sverige och utomlands, uppmärksammat den senaste tiden är trötthetens inverkan på trafiksäkerheten. Inofficiella siffror tyder på att så mycket som 10-20 procent av antalet trafikolyckor är relaterade till trötthet. Vägverket vill nu utöka sin kampanj ”Själv Säker”, som riktar sig till ungdomar i åldern 18-24 år, till att även omfatta trötthetens betydelse i trafiken. Vi har därför fått i uppdrag att, utifrån de unga män vi undersökt, ta fram ett underlag till Vägverket beträffande hur de ska nå unga män i en kommande ”Trött i trafik” kampanj. Den teori vi grundar vår uppsats på är framförallt social marknadsföring vars mål är att influera ett frivilligt beteende hos en speciell målgrupp för att på så vis öka både den personliga och samhällets välfärd som helhet. För att kunna besvara vårt syfte behandlar vi också beteenden och variabler som påverkar dem samt information och kommunikation. För att uppnå vårt syfte har vi genomfört kvalitativa intervjuer med unga män, poliser och trafiklärare. Våra slutsatser är i korthet: De unga männen kör överlag trötta och de har ingen större kunskap om trötthetens effekter vid bilkörning och hur de motverkar dem, de behöver således information. De unga männen uppfattar dock faktaspäckad information som något tråkigt varför budskapet måste ha en emotionell vinkel. På så vis kan de unga männen uppmärksamma och ta till sig informationen. Budskapet skall vidare presenteras som en del av vardagen och/eller som demonstration, med inslag av humor och skrämsel i varierande grad. De här presentationsteknikerna har en hög grad av trovärdighet och ger de unga männen en möjlighet att identifiera sig med situationen och på så sätt ta till sig budskapet. Mediekanaler som med fördel kan användas för att nå de unga männen är annonsering/reklam i TV, radio och dagspress. Andra viktiga verktyg för att kommunicera med dem är att använda sig av Publika Relationer samt personlig försäljning. Den senare, i form av besök av t.ex. polis, trafiklärare och ambulanspersonal, i skolorna i samband med trafikundervisningsdagar.

    Benchlearning as professional development of school leaders in Norway and Sweden2018In: Professional Development in Education, ISSN 1941-5257, E-ISSN 1941-5265, Vol. 44, no 1, p. 62-75Article in journal (Refereed)
    Abstract [en]

    In this paper, we investigate a new national collaborative Benchlearning program for principals in Norway and Sweden. Four process leaders have been running the program. The aim is to give the participants the knowledge to develop a leadership practice and school environment that are more innovative. The program includes theoretical inputs, sharing experiences, school visits, training, and trialing of new leadership practices. Drawing on data from surveys, participants’ reflections, and the leaders’ descriptions of new leadership practice, we examine and identify successful and critical aspects of the learning process. The findings show that principals’ motivation and willingness to start change processes can be created in a synergy between structured school visits, work in learning groups, and a theoretical foundation. Working in groups across schools in two countries seems to enhance principals’ sense of efficacy, which in turn is shown to have a positive effect on their willingness to trial new practices. Two implications of the study are suggested. First, in the design of principal programs, systematic and critical reflection about authentic practice should be the basis. Second, educators should be trained to be process leaders who can support principals’ learning during a critical and social construction of a new practice.

    Vi har sett och hört den, men var då?: En enkätundersökning om barns och vuxnas relation till instrumentet trumpet2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study's purpose is to investigate whether children and parents know the instrument trumpet and the beliefs they have about this instrument.  

     

    My questions are:

     

    • What do 6 and 7-year-olds and their parents know of the instrument trumpet? 
    • What are their beliefs concerning the trumpet and what does the trumpet mean to them? 

     

    To find out about these questions, I have conducted a survey study in Arvika with children in first grade and their parents. 33 adults and 34 children from three schools took part in the survey.

     

    The results showed that knowledge of the trumpet are quite good among 6 and 7-year-olds and their parents. All the respondents in this survey know what the trumpet is, and over one-third of the 67 respondents know about someone who plays the trumpet. Among the children exist no big "celebrity" trumpet player. Instead they mention friends or acquaintances that play the instrument. There were some well-known musicians among adults but it was often aging jazz trumpeters. 6 and 7-year-olds are pretty open-minded about trumpet. They seem to consider both that young, old, men and women could be playing the trumpet. The parents, however, think that men dominate playing the trumpet. Otherwise are the parents also pretty open-minded. The music school appears to have a strong name in Arvika. Many respondents stated that it´s possible to contact the music school if you want to start playing the trumpet. The results also showed that the trumpet is not considered as boring. Most people put it midway between boring and fun to play.

     

    Based on the findings in this study, the trumpet seems to be a well-known and somewhat appreciated instrument among the respondents. At the same time it seems to be a bit out of range from a satisfying reputation.

    Dynamic simulation of solar water heating system using supercritical CO2 as mediating fluid under sub-zero temperature conditions2019In: Applied Thermal Engineering, ISSN 1359-4311, E-ISSN 1873-5606, Vol. 161, article id 114152Article in journal (Refereed)
    Abstract [en]

    CO2 is becoming increasingly important as a mediating fluid, and simulation studies are indispensable for corresponding developments. In this study, a simulation-based performance investigation of a solar water heating system using CO2 as a mediating fluid under sub-zero temperature condition is performed using the TRNSYS (R) software. The maximum performance is achieved at a solar savings fraction of 0.83 during July. The as lowest solar savingss fraction of 0.41 is obtained during December. The annual heat production of the proposed system under Fargo climate is estimated to be about 2545 kWh. An evacuated glass tube solar collector is designed, fabricated and tested for various climate conditions. Moreover, a detailed comparison of the system's performance at sub/supercritical and supercritical pressures shows that the annual heat transfer efficiency of the modeled system is 10% higher at supercritical pressure than at sub/supercritical pressures. This result can be attributd to the strong convection flow of CO2 caused by density inhomogeneities, especially in the near critical region. This condition resuls in high heat transfer rates.

    Flow sheeting software as a tool when teaching Chemical Engineering2011Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to design different chemical processes by using flow sheeting software and to show the usefulness of flow sheeting software as an educational tool. The industries studied are hydrogen, sulfur, nitric acid and ethylene glycol production and a model of drying technique is also included. Firstly, there is an introduction of chemcad as a tool when teaching chemical processes and explanation of each industry which is selected to design. Various production methods for each product are explained and the advantages of the method which is selected to design the chemical flow sheet are discussed. There is also an introduction of the industrial uses of these products formed in Pakistan. The models are designed by using different reactors, heat exchangers, pumps, mixers, boilers and distillation column. The models are designed based upon data taken from literature. The temperature and pressure values are in good agreement with data mentioned in literature. The material balance shown by Chemcad is quite different from data mentioned in literature. Some changes in thermodynamic properties of components in Chemcad software might lead to better agreement between the Chemcad models and literature data. It is not possible to use catalyst in Chemcad to increase the rate of reaction. One possibility is to introduce new components. It is good to use equilibrium reactor when it is required to convert the given component into respective products provided that either conversion of the equilibrium constant are known. It is difficult to study the hidden critical assumptions built in the model when using Gibb’s reactor, as a result there is a deviation in behavior from the system described in the literature. Gibb’s reactor is useful when neither conversion ratio nor equilibrium constant is known.

    GPIB- kommunikation och PID reglering med LabVIEW2009Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    LabVIEW ger en snabb och enkel tillgång till att styra instrument och en mycket stor databas med drivrutiner för DAQ-kort och olika datorgränssnitt (GPIB, serie, osv.).

    Många instrument och datorer kan anslutas till GPIB-bussen.  Detta kan ge en praktisk modell för utveckling av instrumentets styrprogram i LabVIEW med hjälp av GPIB-gränssnittet.

    Ett program i LabVIEW 8.2 med hjälp av GPIB-bussen kan kopplas till t.ex. multimetern (HP-34401A) för att mäta och visa multimeters noggrannhet. Men på grund av fel i drivrutiner för GPIB-gränssnittet kunde jag inte köra programmet med GPIB-bussen.

    Genom att använda LabVIEW 8.2 med hjälp av DAQ-kort kan en PID-regleringsalgoritm simuleras. PID konstrueras med virtuella instrument som innehåller alla nödvändiga komponenter och utrustning som krävs för att reglera någon linjär eller olinjär process exempelvis att nivåreglera två tankar i serie. Här stöter vi på alla de grundläggande regulatorer och får möjlighet att bygga PID med LabVIEW på ett enkelt sätt. Det finns två metoder för att bygga PID. Den första är med matematiska funktioner och den andra är med ’’Simulations functions control’’. Arbetet visar att bägge metoderna fungerar bra för att lösa uppgiften jämfört med färdiga PID-controls på LabVIEW.

    Impact of Tunable Parameters in NB-IoT Stack onthe Energy Consumption2019In: Proceedings of Fifteenth Swedish National Computer Networking Workshop (SNCNW), 2019Conference paper (Refereed)
    Abstract [en]

    This paper studies the impact of tunable parametersin the NB-IoT stack on the energy consumption of a user equipment(UE), e.g., a wireless sensor. NB-IoT is designed to enablemassive machine-type communications for UE while providing abattery lifetime of up to 10 years. To save battery power, most oftime the UE is in dormant state and unreachable. Still, duringthe CONNECTED and IDLE state, correct tuning of criticalparameters, like Discontinuous reception (DRX), and extendedDiscontinuous reception (eDRX), respectively, are essential to savebattery power. Moreover, the DRX and eDRX actions relate tovarious parameters which are needed to be tuned in order toachieve a required UE battery lifetime. The objective of thispaper is to observe the influence of an appropriate tuning ofthese parameters to reduce the risk of an early battery drainage

    An adaptive approach to vehicle trajectory prediction using multimodel Kalman filterIn: European transactions on telecommunications, ISSN 1124-318X, E-ISSN 2161-3915, article id e3734Article in journal (Refereed)
    Abstract [en]

    With the aim to improve road safety services in critical situations, vehicle trajectory and future location prediction are important tasks. An infinite set of possible future trajectories can exit depending on the current state of vehicle motion. In this paper, we present a multimodel-based Extended Kalman Filter (EKF), which is able to predict a set of possible scenarios for vehicle future location. Five different EKF models are proposed in which the current state of a vehicle exists, particularly, a vehicle at intersection or on a curve path. EKF with Interacting Multiple Model framework is explored combinedly for mathematical model creation and probability calculation for that model to be selected for prediction. Three different parameters are considered to create a state vector matrix, which includes vehicle position, velocity, and distance of the vehicle from the intersection. Future location of a vehicle is then used by the software-defined networking controller to further enhance the safety and packet delivery services by the process of flow rule installation intelligently to that specific area only. This way of flow rule installation keeps the controller away from irrelevant areas to install rules, hence, reduces the network overhead exponentially. Proposed models are created and tested in MATLAB with real-time global positioning system logs from Jeju, South Korea.

    Road-Aware Estimation Model for Path Duration in Internet of Vehicles (IoV)2019In: Wireless personal communications, ISSN 0929-6212, E-ISSN 1572-834XArticle in journal (Refereed)
    Abstract [en]

    In Internet of Vehicles (IoV), numerous routing metrics have been used to assess the performance of routing protocols such as, packet delivery ratio, throughput, end-to-end delay and path duration. Path duration is an influential design parameter, among these routing metrics, that determines the performance of vehicular networks. For instance, in highly dynamic scenarios, it can be used to predict link life time in on-demand routing protocols. In this paper, we propose an infrastructure-assisted hybrid road-aware routing protocol which is capable of enhanced vehicle-to-vehicle and vehicle-to-infrastructure communication. A remarkable aspect of the proposed protocol is that it establishes a link between path duration and fundamental design parameters like vehicular velocity, density, hop count and transmission range. Although, a lot of research has been previously performed, a well defined analytical model for IoV is not available in the literature. Precisely, a relation between path duration and vehicular velocity has not been validated in the previous studies. Experimental results show that the increased packet delivery ratio with reduced end-to-end delay can be achieved by the prediction of path duration. Proposed model for path duration is validated by getting experimental results from network simulator 3 (NS3) and analytical results from MATLAB. In addition, SUMO simulator was used to generate real time traffic on the roads of Gangnam district, South Korea.

    Abstract [en]

    Proposing an optimal routing protocol for internet of vehicles with reduced overhead has endured to be a challenge owing to the incompetence of the current architecture to manage flexibility and scalability. The proposed architecture, therefore, consolidates an evolving network standard named as software defined networking in internet of vehicles. Which enables it to handle highly dynamic networks in an abstract way by dividing the data plane from the control plane. Firstly, road-aware routing strategy is introduced: a performance-enhanced routing protocol designed specifically for infrastructure-assisted vehicular networks. In which roads are divided into road segments, with road side units for multi-hop communication. A unique property of the proposed protocol is that it explores the cellular network to relay control messages to and from the controller with low latency. The concept of edge controller is introduced as an operational backbone of the vehicle grid in internet of vehicles, to have a real-time vehicle topology. Last but not least, a novel mathematical model is estimated which assists primary controller in a way to find not only a shortest but a durable path. The results illustrate the significant performance of the proposed protocol in terms of availability with limited routing overhead. In addition, we also found that edge controller contributes mainly to minimizes the path failure in the network.

    Den stressade eleven: En enkätstudie om stressorer som utsätter barnen för stress2011Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Researchers claim that stress has become a word of fashion and is now frequently used. They also state that there is no accepted definition that can easily describe the concept. In this essay, I have examined children and stress. The aim of the diploma work is to illustrate stress more closely the stress concept, the underlying reasons that can influence children and how teachers and school staff support children in their stress handling. My three issues are: What is stress? What stressors put children, at home and at school, in a stress situation? How can teachers help children to manage their stress? The diploma work is based on a literature study in order to find out what has been written on the subject in earlier research. Moreover, the work is based on four interviews with three class teachers and a school nurse in order to illustrate their experiences of what stresses children at school. In order to get a good base for the work the children's participation was of utmost importance to get a good base for the work, therefore questionnaires were given to 89 children in class 4 and 5. The results of the questionnaires showed that children had little or no knowledge of the stress concept. They associate it most often with lack of time and having to hurry. Children can be stressed just like adults. In addition, stress levels differ greatly between them, which means that some children feel more stress-tolerant than others. The conclusion that can be drawn from this study is that the child's environment affects the child, school and home being the greatest stress factors.

    Abstract [en]

    Microextraction by packed sorbent (MEPS) is a new technique for sample preparation that can be connected on-line with liquid chromatography (LC) or gas chromatography (GC) systems without any modifications. This article describes the use of MEPS in clinical and preclinical studies to quantify different drugs in whole blood samples. MEPS was used to determine cyclophosphamide in mouse blood from preclinical g studies using 20 mu L of blood samples. The interday accuracies and 0 precisions ranged from 107-109% and from 2.0-7.0%, respectively. The determination of four immunosuppressive drugs in human blood by MEPS and liquid chromatography-mass spectrometry (LC-MS) is described. The method showed a good selectivity and sensitivity. The calibration curves for everolimus, sirolimus, and tacrolimus ranged from 0.5 to 50 ng/mL and for cyclosporine from 3.0 to 1500 ng/mL. Intraday precisions for the studied immunosuppressive drugs were 2.0-11.7% and interday precision ranged from 5.1 to 13.7% (CV).

    Microextraction in Packed Syringe Online with Liquid Chromatography-Tandem Mass Spectrometry: Molecularly imprinted polymer as packing material for MEPS in selective extraction of ropivacaine from plasma2006In: Journal of Liquid Chromatography & Related Technologies, ISSN 1082-6076, E-ISSN 1520-572X, Vol. 29, no 12, p. 1725-1736Article in journal (Refereed)
    Abstract [en]

    The excellent performance of a new sample preparation method, microextraction in packed syringe (MEPS), was recently illustrated by online LC‐MS and GS‐MS assays of local anaesthetics in plasma samples. In the method, approximately 1 mg of solid packing material was inserted into a syringe (100–250 µL) as a plug. Sample preparation took place on the packed bed. The new method was easy to use, fully automated, of low cost, and rapid in comparison with previously used methods. This paper presents the use of molecularly imprinted polymers (MIPs) as packing material for higher extraction selectivity. Development and validation of a method for MIP‐MEPS online with LC‐MS‐MS using ropivacaine in plasma as model compound were investigated. A bupivacaine imprinted polymer was used. The method was validated and the standard curves were evaluated by means of quadratic regression and weighted by inverse of the concentration: 1/x for the calibration range 2–2000 nM. The applied polymer could be used more than 100 times before the syringe was discarded. The extraction recovery was 60%. The results showed high correlation coefficients (R 2 >0.999) for all runs. The accuracy, given as a percentage deviation from the nominal concentration values, ranged from -6% to 3%. The precision, given as the relative standard deviation, at three different concentrations (QC samples) was consistently about 3% to 10%. The limit of quantification was 2 nM.
