Löneandelens förändring 1975-2010 : Teori och empiri
Sedan 1970-talet har större delen av världen upplevt en minskande löneandelen. Vi försöker förklara utvecklingen med en enklare modell bestående av två typer av arbetskraft. Vi visar att på kort sikt påverkar arbetskraftens sammansättning löneandelens utveckling vid arbetskrafts utbudschocker.Empirisk studie av paneldata ger inga statistiskt signifikanta resultat vilket skulle kunna orsakas av bristfällig data och att de länder för vilka data existerar är i hög grad homogena..
Områdessökning i geografiskt associerad data
This thesis considers the problems associated with searches in insufficiently geographically tagged data. The thesis was carried out at Booli Search Technologies AB, a company developing a search engine for the Swedish real estate market.The aim of the thesis is to identify some areas of possible improvements of the company?s existing technical platform, perform a benchmarking among similar services, suggest possible solutions and lastly, build a prototype from one of the suggested solutions.The thesis starts out with defining the problems that the search engine faces: some areas are not possible to perform searches on, the users are not presented with the full search result that they expect, some results are placed incorrectly on the map associated with the search results and results are also not described with enough geographical information. These problems are due to the fact that the data retrieved at the indexing stage in the company?s information retrieval process are insufficient and incomplete.As a result of a benchmarking process and after discussing the results, severalinteresting solutions were identified.
Personuppgifteshantering och identifiering inom myndighet, skola och förtag
The authors of this thesis have studied the handling of personal information in various kinds of organizations, because the perception is that the knowledge in this area is weak relative to the weight of the subject.The purpose of this paper has been partly to shed light on how knowledge of this area in the organizations that we have visited during the study but also to answer questions about handling, knowledge and security, and identification of individuals in different systems. What kind of problems the processing of these data creates and why these problems occur.In the beginning of our study we understood the importance of using the correct identifier and therefore chose also to examine what the various identifiers used by the organizations and why they chose these particular identifiers.In the qualitative analysis, Datainspektionen´s general rules and advice has been used as a basis together with the laws applicable to the organizations to get a good picture of how management of personal information is in these organizations.What we have found in this paper is that knowledge about how personal data is handled and what laws and rules are saying is very much dependent on how central the information is to these organization's activities. The police use so many different types of records for their organization to function well and they have very good knowledge of laws and regulations. In contrast, schools that do not handle as much of personal data themselves nor have the same knowledge among staff and do not have enough resources to cope with keeping the same knowledge base as the police. This is something that applies to all types of handling, depending on how important the information is for the organization, the better the security and knowledge in handling the data is..

Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips
Stump biomass is energy rich and stump harvesting for use as fuel become more and more
interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in
Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not
been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of
stump are probably of great importance to make it accepted as fuel. It is therefore rewarding
to carry out an investigation in this area for stump.
This report represents results from a diploma project, which was aimed to develop a fixed bed
reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic
modelling employing Ozawa method and different kinetic models including one-step and
three-pseudo-component models.
Nätverksbaserade informationssystem : Standardprotokoll ANSI Z39.50/OSI SR
This master thesis examines the development of the two earlier independent IR protocols Z39.50 and SR (Search and Retrieve, ISO 10162/10163), now Z39.50/SR, from the beginning of the 80s to 1996 and their functionality in the client/server environment.Z39.50 applications in library systems will allow easy access to information regardless of platform or location. The use of Z39.50 will create a new user environment. Almost all the library systems of the market support the Z39.50 and surprisingly the use of it in Sweden lied on a very low leve! in 1996. This thesis was followed-up by an interview and a questioner among the Swedish Z39.50 users. They could see a huge potential of development concerning the future IR process.
Det (in)formella mötet som formas och formar : En kvalitativ studie om handläggare och klienters upplevelser av interaktionen i utredningsarbetet inom försörjningsstöd
The purpose with this study was to examine six caseworkers and two clients? experiences of interaction in the investigative work of social assistance. Moreover, how the interaction between caseworkers and clients are affected by the structure of the social assistance unit. The study also wanted to show how interaction rituals contribute to the change in assessment procedure in the investigative work. The study even aimed to highlight the ways in which social exclusion occurs in investigative work from caseworkers and client?s capital and gender.
Språk och minne ? hinder eller verktyg? : En studie om pedagogers förhållningssätt till elever med språkstörning i lärandesituationer, med fokus på arbetsminne
The purpose of this study is to generate knowledge about how teachers relate to students with language impairment in learning situations, with particular focus on working memory. The questions are: What kind of knowledge do teachers have regarding language impairment and working memory?, What experience do teachers have regarding lack of working memory abilities among students with language impairment and which consequences do the teachers believe such defects may have for the students? and How can teachers create a learning environment that reduces the working memory demand for students with language impairment? A review of the field shows that there are gaps to fill regarding students with language impairment and working memory. Language impairment has so far been neglected by researchers and within the public debate. How working memory capacity affects the students has only recently begun to receive attention in school and research.
Datamodell för metadata och grunddata över MD Ns geografiska information
Norra Militärdistriktet, MD N, har använt sig av geografiska informationssystem, GIS, under en längre tid. Dessa geografiska data lagras idag i en filstruktur som byggts ut allt eftersom data har blivit tillgänglig i digital form. Den geografiska informationen på MD N är i behov av en översyn för att få det mer strukturerat och användarvänligt. Målet med examensarbetet är en datamodell som ska kunna följas vid uppbyggnaden av MD N:s databas för metadata. Målet är även en modell som ska kunna följas vid omstrukturering av MD N:s geografiska grunddata.
Hang n' GO : Cykelhållaren som alltid finns tillgänglig
This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.

Partialevaluering : Specialisering av program Utformning av en laboration
Partialevaluering av program är ett intressant ämne både för att optimera programmen men även för möjligheterna att kompilera program med en interpretator.Denna rapport beskriver hur laborationerna i kursen Data och Programstrukturer på Linköpings Universitet, som är helt baserad på Abelson & Sussmans bok Structure and Interpretation of Computer Programs kan utökas så att den även går igenom partialevaluering. Som grund i laborationsunderlaget ligger en enkel partialevaluator för en delmängd av det funktionella språket Scheme som utvecklas för underlaget.Rapporten består i huvudsak av tre delar, i början introduceras läsaren till partialevaluering. Vi förklarar hur man av ett generellt program och viss känd information vill skapa ett nytt specialiserat program. Två vanliga metoder att göra partialevaluering på beskrivs men i första hand fokuserar rapporten på den metod som implementerats, nämligen offline metoden. Specialisering av ett program med en offline partialevaluator börjar med en analys av programmet som sedan specialiseras.
Sensorfusion för ACC-System
Genom att fusionera (sammanföra) data från olika sensorer kan ett resultat uppnås som ger mer än de enskilda sensorerna var för sig. Här utreds vilka sensorer och sensorfusionsmetoder som kan vara aktuella att använda för Scanias adaptiva farthållare (ACC). Den adaptiva farthållaren anpassar det egna fordonets hastighet inte bara till en förinställd hastighet utan även till framförvarande fordons hastighet. Scanias ACC-system använder idag en radar för måldetektering.Det finns ett antal algoritmer och arkitekturer som passar för sensorfusionssystem beroende på nivån hos sensordatan och användningsområdet. Minstakvadratmetoder kan användas då data ska matchas mot en fysisk modell, ofta med lågnivådata.
Kapitalstruktur : Skuldsättningsgrad och avkastning hos svenska finansbolag
In a time when economic crises relieving one another, it is especially interesting to study how companies choose to finance their operations. Since there is a lack of studies that include banks, and their capital structures, with the rest of the finance market, it is uncertain whether the theories of capital structure are applicable. Therefore, this essay aims to study whether there is any correlation between the two variables debt-equity ratio and return on equity (ROE) for Swedish corporations on the finance market.In accordance with the theorems that the professors Modigliani and Miller filed, in 1958 and 1961, which describes a clear link between debts, increase corporate value through the tax shield and indirectly increased yields. Although these theorems are the foundation of the modern research they focus on perfect markets. Therefore, this paper has also chosen to place great emphasis on theories such as Trade-off and Pecking-order.
