The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.

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.

Studien utreder vilka problem som föreligger vid agila- och vattenfallsbaserade utvecklingsmetoder samt presenterar förslag på hur dessa problem kan komma att lösas. För att besvara dessa frågor har djupgående semistrukturerade intervjuer med designers med erfarenheter av metoderna intervjuats. Intervjumaterialet har transkriberats, kodats och analyserats i syfte att kartlägga de problem som finns. I de intervjuer som genomförts med vattenfallsdesigners har det uttryckts problem med att metoden upplevts som långsam, tungdokumenterad och att relationen med utvecklarna ansetts som komplex. De agila designers har uttryckt problem med att mer efterforskning krävts.

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

Before the autumn term 2011 the Swedish compulsory school adopted new syllabuses in relation to, inter alia, religion. Changes within the religion topic have historically been a heavily debated issue among decision-makers, interest groups and the church, where the role of the Christianity has been particularly controversial.The main purpose of this study is therefore to investigate how the Swedish compulsory school?s teaching of Christianity has changed over the years. I have in order to conduct this study applied a descriptive method as well as a content analysis. The Swedish compulsory school?s current and historical syllabuses in religion have served as basis for this study.The outcome of this study clearly shows that the Christianity has received less influence to the benefit of other topics.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

Effektiva copingstrategier kan öka arbetstillfredsställelse, minska spänningar, sänka personalomsättning och frånvaro samt leda till andra positiva utfall för både individer och arbetsgivare (Parks, 1990). Syftet med denna uppsats var att få en djupare förståelse av hur småföretagare upplever problem med anställda samt att undersöka vilka copingstrategier som används för att hantera olika typer av problem. Frågeställningarna var, vilka problem hanteras med emotionsfokuserade copingstrategier? och vilka problem hanteras med problemfokuserade copingstrategier? Respondenterna i undersökningen var nio småföretagare samtliga var män i åldrarna 39-71 år. Totalt identifierades 27 problem som delades in i sex olika kategorier.

The aim of this study is to point out variations of practices in the relationship between professionals of service occupations and their clients. The material consists of four openly conducted thematic interviews with male professionals who work in the environment of their clients' homes.The main theoretical approach of this analysisis undertaken with ethnicity in mind.The practices identified aim to throw light on the boundaries between the differing cultures of professionals and their clients.The analytical termsboundary reduction and boundary maintenanceare used in this research.The two-stage analysis points out different practicesused, in chronological order, during contact between professionals and their clients. This is followed by a statement of the themes which connect, primarily fromthe professional perspective. The results indicate an intimate connection between intercultural and transcultural aspects through the use of cultural transparancy, which is a strategy connecting different roles, aswell as use of loophole tacticsthat afford the possibility of definingspace, place and relationship.It's illustrated how the professionals operate from "within the structures and worldview" of the client, and this analysis also reveals a glimpse of the potential for cultural changein the meeting between different cultures..

Interorganisatoriska informationssystem (IOS) är en teknik som finns att tillgå organisationer vilket gör det möjligt för dessa att på ett relativt enkelt sätt kommunicera direkt med deras affärspartner och utbyta data som är till nytta i deras affärsrelation. IOS minskar kostnaden för utbyte av information och ökar organisationernas informationstillgänglighet. Vi kommer i denna studie undersöka vilka specifika problem de olika organisationerna upplever vid drift av IOS. Vi vill även uppmärksamma varför organisationer upplever dessa problem, samt även visa på förebyggande åtgärder. Undersökningen genomfördes med hjälp av kvalitativa intervjuer med fyra organisationer.

During Sweden's economic crisis in the early 1990s a governmental committe of prominent economic and political experts were gathered to produce an analysis of and suggestions to the solution of that crisis. The committe produced a report that became widely commented in the media and in parliment. The report anc the reception of it gives us insights in how the boundaries between social science and politics are created an how new fields of expertise is added to a science. This thesis uses a constructivist approach to explore how the techniques of the economic science were made into credible means of knowöedge production outside of the field where it traditionally holds epistemological authority. Working from the assumption that language does things to the objects that it describes I claim that the episode investigated in this thesis was shaped by the committee's ability to define the economic crissi and thus making it into a knowable object.

Effektivare offentliga upphandlingar kan enligt tidigare forskning innebära stora möjligheter till besparingar för det svenska samhället. Upphandling av läkemedel till slutenvården är ett område som många aktörer identifierat som problematiskt. Syftet med studien är därför att identifiera problem och potentiella lösningar med upphandling av läkemedel. Tillvägagångssättet var att analysera allmänt påtalade problem och lösningar med upphandling samt empiriska resultat från intervjuer och en enkät utifrån problem finding and problem solving metoden. De empiriska resultaten var fyra huvudsakliga problem: (1) olikformighet i kravspecifikationer, (2) bristande dialog mellan aktörer, (3) för kort tid mellan tilldelningsbeslut och avtalsstart samt (4) omfattande dokumenthantering.

This thesis uses the ?What's the problem?-approach developed by Carol LeeBacchi. This approach studies how the problem that a certain policy is supposedto take care of is represented. Each representation will rest upon certainassumptions and will accordingly support certain solutions while other solutionswill be considered less suitable to the problem as it is represented.The thesis therefore evaluates the competing problem representations forgender mainstreaming in Sweden. The theory chapter explores two developmentpossibilities for gender mainstreaming, based on diversity and deliberativedemocracy.

In this thesis we study four groups of students in grade 8, 9 and 10 when they try to solve a classical mathematical problem: Which rectangle with given circumference has the largest area? The aim of the study was too see how the students did to solve a mathematichal problem?The survey shows that students have rather poor strategies to solve mathematical problems. The most common mistake is that students don?t put much energy to understand the problem before trying to solve it. They have no strategies.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.
