Utveckling av virtuella världen "Krimlab" - Spelbaserat lärande för tonåringar
I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.
Varför gör de inte vad de ska? Hur det kommer sig att ett infört arbetssätt på Försäkringskassan inte tillämpas så som avsetts
The aim of the present paper was to see why a recommended course of action is not always followed in the way it is supposed to. The paper deals with a new method (SFA-metoden) used by The Social Insurance Agency in working with sick-listed people. Aspects that are elaborated on are local effects of the method at its introduction, case managers work conditions, and control of the implementation of the method. Two different methods of investigation have been employed. On the one hand, previous reports on the method have been analysed, and, on the other hand, two focus groups interviews, one consisting of case managers´ working with the method, and one constituted by their supervisors have been carried out.The results have been analysed in accordance with, on the one hand, the theory of street level bureaucrats and, on the other hand, certain concepts applied in the new institutionalism.
Skolrelaterad stress hos kvinnliga gymnasieelever : En jämförelse mellan yrkesförberedande och teoretiskt program
AbstractLoeva, J (2013). Schoolrelated stress in female students ? a comparison between vocational and theoretical program. The Academy for health and working life, University of Gavle.Purpose: To investigate and compare perceived stress and recovery among Swedish femalestudents (high school, third degree) in a vocational program versus a theoretical program.Method: A cross-sectional study was conducted on forty female students (vocationalprogram, n=20; theoretical, n=20) to give a cross section of the population in question. Datawas collected by questionnaries, which included questions on perceived stress and energylevels, demand, control and social support at school.
SELF CONTROL
SELF CONTROL är ett undersökande examensarbete i textildesign. Med en textil hantverksmetod undersöker jag mötet mellan kontroll, tidsåtgång och material. Detta med utgångspunkt i en feministisk diskurs. Jag ser kontroll som något som exkluderar, censurerar och begränsar möjliga uttryck inom textilt hantverk på samma sätt som kvinnokroppen kontrolleras i ett patriarkat. Jag har använt mig utav en performativ och repetitiv metod som aktivt har gått ut på att bryta mot föreställningar om hur hantverket ska utföras.
Implementering av en ny chefsroll : Fallstudie av LRF-Konsult
As companies worldwide are in search of competitiveness and larger shares of the market, organizational change has become a key-factor to sustain a competitive edge. But as organizations consist of people, the human aspect of change is not to be disregarded. When change occurs, humans need time to find their new role in the organization, a process that takes time. In this thesis the authors ask themselves what an implementation process of a new managerial role looks like. To answer this question they?ve studied LRF Konsult.
Föräldrar, barn och genus : Föräldrars tankar och funderingar kring genusfrågor vid lån av barnböcker
This paper intends to examine how parents think and reflect on gender issues when they borrow books for their children at the library. The theory applied is Yvonne Hirdman?s theory of a gender system. A questionnaire was made available at the Children's department of Uppsala City Library in February, 2010. The material was compiled and analyzed with the intention to try to detect trends, patterns and themes, rather than statistics and hard data.Parents in the study perceive themselves as gender-conscious.

Virtuell hållfasthetsprovning av en turistbuss
The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China
Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.
Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Energieffektivisering i flerbostadshus : En studie av incitament och hinder i Uppsala
The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.
Jämförande analys av drivlinor och dess bränslesorter för fordon av hybrid, elektrisk och traditionell typ
The development of solar photovoltaic (PV) is increasing,with declining module prices and with a strongenvironmental profile. Policies are developed around theworld to achieve the targets set for renewable energy.In Helsingborg, the local power company Öresundskraft isworking with solar PV to achieve the goals of the city.With their vision: - Energy for a Better World and Powerfor the Region, their work with developing the local solarPV market is continuing and the next step is to create asolar PV policy. Today their offer is 1 SEK/kWh for theexcess electricity delivered to the grid.It turns out that compensating the customer is a vitalpolicy and it has to be dynamic to follow the decisions ofpolitics. The same survey shows indeed, thatenvironmental and technical part is of interest. Solar PVwill be supported locally to act on environmentalsustainability and locally produced electricity and withthis Öresundskrafts vision will be achieved..
Högskolestudenters motivation : Har självkänsla och locus of control någon betydelse?
Motivation är en viktig drivkraft för individers beteende. Den har betydelse för att handlingen såväl påbörjas som uppehålls. Forskning inom området har konstaterat att motivation uppkommer av både inre och yttre faktorer samt att en del handlingar är relativt omotiverade. Den hierarkiska modellen för inre och yttre motivation anger även att motivation förekommer på flera nivåer inom individen. Studien undersökte relationen mellan högskolestudenters kontextbundna motivation, globala självkänsla och generaliserade locus of control.
Fonologisk medvetenhet i förskoleklass : En interventionsstudie
International studies show that literacy skills have deteriorated among Swedish students. Empirical evidence states that before being able to learn to read it is important to have phonological awareness. From this perspective, an intervention study was launched to examine whether pupils´ phonological awareness could be enhanced through the work of a special model during a limited time. The aim of the study is to investigate whether six pupils in preschool develop phonological awareness based on Bornholmsmodellen during a limited period of time. The control group was made up of the remaining pupils in the preschool class.
Emotionell kompetens : om möjligheter till utveckling och betydelse för ett effektivt ledarskap
Purpose of the study was to illustrate how emotional competence can be important for leadership and to explore the possibility of improving emotion perception ability after training. Participants in this study were 40 managers, divided into control and experimental group, within public administration. The participants implemented a data-based emotion perception test, which were done twice at every occasion, with intervention consisting of information or education between test- and retest. The result showed a clear improvement after intervention, in which no difference was found between control and experimental group, which has been discussed on the basis of the likelihood of a training effect occurred between test-retest. Conclusions about emotional competence or leadership ability could not be drawn from the results of the emotion perception test.
