This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

Syftet med studien var att undersöka om grad av överkonfidens kunde variera mellan olika ämnesområden, med kontroll för svårighetsgrad. Ytterligare syfte var att undersöka hur överkonfidens varierar mellan olika bedömningstyper och personer. Mätinstrumenten som användes var dels frågeformulär om melodifestivalvinnare och nobelpristagare med självbedömningsfrågor om prestation, samt frågeformulär om extraversion och neuroticism. Totalt deltog 139 respondenter. Resultatet visade realistisk bedömning inom ämnesområdet melodifestivalvinnare och underkonfidens inom ämnesområdet nobelpristagare, med kontroll för svårighetsgrad.

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.

Husqvarna AB operates two warehouses located in the area of Jönköping. The most important task is to manage the large volume fluctuations during the peak season.

Syftet med denna uppsats är att beskriva vilka föreställningar chefer har angående vilka kompetenser som krävs för att göra karriär i Sverige. Genom empirin fann vi att ett antal olika kompetenser är nödvändiga för att göra karriär i Sverige. För att bli en av dem som kommer på tal när en chefstjänst ska tillsättas krävs att rätt personer uppmärksammar en individs prestation. Det krävs även rätt klädsel, rätt språkbruk, social kompetens samt ett välutvecklat nätverk. Dessa kompetenser skiljer sig åt mellan kvinnor och män.The purpose with the thesis is to describe which conceptions that managers have regarding the competences that are acquired to have a career in Sweden.

Hur upplever vi former och fa?rger na?r de flyttas fra?n ett papper till ljusprojektioner? Det ha?r a?r en av fra?gorna jag ville fa? svar pa? na?r jag bo?rjade med detta projekt. Allting utmynnade sig i en studie jag valt att kalla fo?r, Ljusprojektioner och ra?nder. Det a?r ett experimenterande arbete da?r former, mo?nster och den upplevda erfarenheten av dem har underso?kts ur ett fenomenologiskt perspektiv.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

The use of thin and attractive models to promote companies' products is widespread among marketers. This is true even for companies whose products have little or no association with beauty or body weight. As the proportion of overweight people continues to grow in many developed countries the ideals used by marketers to attract customers strays further away from the actual attributes of the customers themselves. What is little understood is what effect overweight has on the efficiency of the product promoter. Some limited research has studied how the efficiency of the product promoters in printed advertisements is affected by the existence of congruence between the product promoter and the product itself.

The Oresund Region, consisting of the Swedish county of Scania and the Danish islands of Sealand, Lolland, Falster and Bornholm, is widely recognised as a successful example of European cross-border co-operation. The purpose of this region building project is to form a cross-border fully integrated functional region in order to accomplish a high level of economic growth and employment.This thesis argues, by the means of discourse analysis, that the project can be viewed as a kind of post-politics, defined as a politics that under a neoliberal hegemonic consensus strives to manipulate citizens (and to redefine them as consumers and investors) into better economic performance.This manipulation is carried out by extensive discourse production aimed at convincing people that the Oresund Region exists, that it is a successful region, and that the people who inhabit it are also successful. The deliberate vagueness and contradictory character of the Oresund discourse is investigated and explained as a discursive strategy to incorporate as many views and desires as possible..

Syftet med denna kvalitativa studie var att undersöka vilken inverkan boendesegregation har på ungdomars utbildningsmöjligheter. Studien innefattade 15 vetenskapliga artiklar och rapporter som analyserades med hjälp av systemteori och Bourdieus teori om kapitalformer. Resultaten visade att den sociala omgivningen är en viktig faktor för ungdomarnas studieresultat. Bostadsområdets vuxna är viktiga som rollmodeller. Normer och beteenden i närmaste omgivningen spelar en viktig roll i ungdomarnas socialisering.

Jag har kommit fram till i denna c-uppsats att den anti-estetiska och visuella aspekten i für Alle-konsten i huvudsak bygger på Wahlbeck/Ericssons användande av modern teknik såsom videokamera, ljud och visuell ljus-teknik. Detta i kombination med alternativa former för att visa upp konsten, t ex genom teater, likt spelfilmen och såpoperans estetik. Jag har även kommit fram till att det konstnärliga formatet och produkterna som sådana (Cd, Film och Video) är av betydelse för det anti-estetiska uttrycket i für Alle-konsten. Den anti-estetiska frågeställningen har jag fått svar på genom att studera tidigare forskares texter om anti-estetik, t ex. Keith Moxeys text om Heironymus Bosch, Folke Edwards text om Futurism, gränslös mediauppfattning och 60-talets konst samt Hal Fosters text om anti-estetiken.

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.
