This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..

Title:What influences the assessment of addiction treatment? - Factors that may affect thechoice of interventionsThere are few studies on trauma and the importance of religion for the professional handlingof abuse clients in a Swedish context. It is therefore appropriate to examine the role of suchfactors. This study examines whether experienced trauma in childhood or religious beliefsinfluence the assessment and selection of input in fictitious cases. To examine this created sixvignettes.

This thesis aims to analyse ontology, primarily as the word is used in the context of the Semantic Web. One of the main questions is how ontologies relate to classification and thesauri, two concepts well known within Library and Information Science. The vision of the Semantic Web, a more intelligent addition to the current World Wide Web, has raised the question of how to deal with information scattered over a multitude of locations, stored in different formats, written in different languages et cetera. This issue is in many ways similar to the classical problems encountered in library science: how to classify and categorise large amounts of information. The use of ontologies is one of the main steps leading to the Semantic Web, as well as a tool which can be used in other areas of information organisation and management.

Our aim of this study is to analyze how the concept of reasonable standard of living is by assistance officers in geriatric care, as well as the impact of their discretion on the assessment. We conducted a qualitative study with the help of interviews. During the collection of the empirical material, we have experienced greater confusion among assistance officers opinion about the concept of reasonable standard of living. We lacked a clear answer to the concept content. The interview subjects' responses did not differ so much, they said, among other things, that the concept is difficult to interpret, fuzzy, or that they do not have a good understanding of it.

This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook. The social network site Facebook has since its start in 2004 made a mark in modern communication. Today in 2010 the site has more than 500 million users. This paper wants to study what happens to other types of communication.

This study was conducted at Glimek AB, a company that has chosen to decentralize its central storage unit in order to increase production efficiencies. The purpose of the study was to identify the problems in the production cycle that lead to the decision to decentralize the central storage unit, as well as identifying what the decentralization entails. The effects of the decentralization have not been analyzed in the study, and consequently neither financial nor production disadvantages have been considered.Appropriate questions were formulated based on the chosen underlying theories, and were asked to selected individuals with relevant knowledge. The study is based on the information that was gathered from interviews with management as well as staff within the company. In addition, supporting information such as flowcharts, drawings, orders and decision support documents were supplied by the company.

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style..

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

Om man vill skapa ett realistiskt hav inom Computer Graphics är det viktigt att man har snygga övergångar till andra material. Ett exempel på detta är stränder och det är precis där fokusen på den här studien har legat. Studien gick ut på att hitta en enklare lösning på att visuellt förbättra stränder inom Computer Graphics. För att göra detta så testade två olika metoder i olika experiment. Den ena tekniken som testades var att simulera partiklar för att få fram en bättre strandlinje och de andra var att skapa en shader för att förbättra den.

Genomförda undersökningar visar att formativ bedömning förbättrar elevers inlärning och förståelse. Den svenska läroplanen från 2011 ger tydliga indikationer på att formativ bedömning ska inkluderas i undervisningen. Vår diskussion i denna uppsats är därför aktuell och den visar hur forskare artikulerar fenomenet formativ bedömning. Litteraturstudien inkluderar information om vad formativ bedömning innebär och förslag på hur man kan arbeta utifrån ett sådant arbetssätt. Vår studie visar att de viktigaste komponenterna inom formativ bedömning är att tydliggöra målen, återkoppling samt själv- och kamratbedömning.

Scientists and educational psychologists research have seen on self-regulated learning as learningconstruction. Every scientists have developed their own terms and concepts in the events of explaining how self-regulation affects students learning-process. Keyprocesses in previous studies is the importance of the active choice, to be goal-oriented,and awareness is what students need to self-regulate their own learning. The purpose of this study is to examine how students use different educational learning strategies based on the principles for self-regulated learning (SRL). From the process of the previous research, different concepts and terms have been divided into three key concepts titled:Active choices and actions, Goal-orientation and goal setting, as well as consciousness and self-awareness.
