This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The most common method for identifying merchandise in the commerce is by barcodes. Symbian OS is an advanced operating system aimed at cell phones and the most commonly used in smart phones. Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.

E-handelskunder vill ha möjlighet att handla snabbt och direkt oavsett tidpunkt eller plats. Därför är integration mellan e-handel och affärssystem viktigt för en lyckad e-handelslösning. Detta känner de flesta företag till och idag är inte tekniken något större problem. Att företag trots detta inte integrerar systemen beror på verksamhetsbaserade orsaker. De stora kostnader som integrationen i initialskedet medför anges också som ett skäl till att systemen inte integreras, kunskap saknas om de långsiktiga vinster som integrationen ger.

Följande rapport behandlar konstruktionen av ett system som kontinuerligt ska analysera kvaliteten på vatten. Systemet är uppdelat i mätenheter som utför själva mätningen och en centraliserad server som man kan koppla upp sig mot för att övervaka/justera sina mätenheter.Uppdragsgivaren till projektet var forskare från IFM på Linköpings universitet. De hade sedan tidigare ett fungerande system för att analysera vatten kontinuerligt. Vår uppgift var att ersätta deras system med ett nytt, som var baserat på mindre och billigare hårdvara. Vi har visat att systemet går att implementera på den önskade hårdvaran.Rapporten skildrar även hur projektgruppen tog designbeslut under utvecklingsfasen.

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

Bipolär sjukdom (BS) är en kronisk sjukdom med återkommande perioder av mani och depression. Den bryter oftast fram i tonåren men i många fall diagnostiseras den inte förrän patienten är runt 30 år. Behandling för BS är livslång medicinering med stämningsstabiliserande läkemedel, i första hand litium, kombinerat med anti-depressiva läkemedel och anti-psykotiska läkemedel. Läkemedelsbehandling kombineras med psykoedukativ behandling eller kognitivbeteende terapi (KBT). En intensivbehandling följer efter det att diagnosen är ställd och det tar ofta upp till 2 år för patienten att hitta en balans i livet.Syftet med denna studie är att få en uppfattning om hur det är att leva med bipolär sjukdom.

The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.

Vid affärssystembyten väljs ibland standardsystem framför egenutvecklade system. En orsak är att egenutvecklade system är dyra och komplicerade att bygga. Flera företag tycker också att det är smidigare att implementera standardsystem då dessa är utformade som en paketlösning där samtliga moduler är integrerade.Ett problem för företag är att välja "rätt" standardsystem. Ett arbetsmål i denna uppsats är att ta reda på i hur stor utsträckning företag använder sig av en metod i anskaffningsprocessen. Huvudfokus är att ta reda på vad företag tycker är viktigast att anpassa - verksamhet eller system? Ett annat delmål är att titta på hur företagskulturen förändras vid ett standardsysteminförande.I undersökningen görs sex företagsintervjuer hos företag som alla har anskaffat standardsystem.

Because of an increasing demand from customers and changing external environment, there is a need for continuous improvements, for both manufacturing and service organizations, to meet these demands. Manufacturing organizations have been working systematically with quality improvements for a long time, but it has not been as common for service organizations. Because of that the methods to use for implementation of the systematic improvements have not been designed to fit service organizations, and not either for public organizations. The purpose of this thesis is to explain if and why the Swedish Road Administration?s organizational culture and handling of ideas and deviation support an implementation of continuous improvement management.

Technology based self-service (TBSS) used in supermarket self-scanning checkouts is a relatively new phenomenon in Sweden. Studies on TBSS as a self- checkout device have been formerly carried out but with focus on the customer perspective. The authors therefore saw a challenge in covering the self-scan checkout concept, from a company perspective. The purpose of this research paper is to investigate, through a management perspective, the changes brought about by implementing an innovative TBSS system in Swedish supermarkets, and its effect on the competitiveness of the company. This is done by presenting and linking the theoretical framework and empirical study in the research.

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

The purpose with this thesis is to analyse images in the confirmationbook Via Mystica from a gender perspective. By using two different ways to analyse the pictures, a content analysis and a semiotic picture analysis, the result was as follows: The pictures of men an women fortifies the construction of gender. The girls in the pictures are represented as caregivers and comforters, while the boys are represented as strong and tough. The four pictures from the semiotic picture analyses showed how easy it was to categorise the men and the women in the photos in opposing stereotypes. The women are percieved as weak and submissive while the men were either strong criminals or a strong hero.

The number of sawmills in Sweden has decreased dramatically since the 1980s and the trend looks set to continue. The sawmills that are left instead becomes larger and are situated farther apart. In northern Sweden, they are concentrated along the coastline.In our study, we compared conditions for running a sawmill in inland areas and coastal areas and looked at what factors have the greatest impact on the profitability of the sawmill in northern Sweden.We chose to compare different locals conditions for a sawmill that only sawn pine timber and had an annual raw material requirements of 300 000 m3ub per year. By analyzing the kNN-data from the Swedish National Forest Inventory we have taken out the size of the timber volume at each site and its catchment. We have also looked at possible competitors in the areas that may affect the purchase price of the commodity.

This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.
