Flexibel lärandemiljö: En studie av ett högskolebiblioteks lokalförändringar utifrån kunskapssyn och lärandeperspektiv
The aim of the study is to examine how different factors,such as views on how knowledge is produced and howlearning takes place, effect the way an academic librarymanages space. This is done by looking into how a specificlibrary, namely Library & Learning Resources (LLR) at theUniversity of Borås, by re-planning the building?s structure,design and functions, can support the students? differentstudying habits. The analysis is performed by using a theoreticalperspective built by a model first created by thearchitect Daniel Koch. The model is designed to look uponhow space produces meaning and knowledge.
Delegationsdemokrati - En studie av Hyresgästföreningens förhandlingsdelegationer
The aim of this essay is, with reference to a close study on the negotiation delegations of the Tenant Association, to examine the principals of democracy in relation to distribution of power and participation, efficiency and professionalism. This is done with the intention to understand the Tenant Association's view on its own commission as negotiator, according to democracy. The investigation is carried out on the Tenant Association in the Swedish cities of Stockholm, Malmö and Gothenborg.The data acquisition was obtained by using a questionnaire and through interviews with representatives from the Tenant Association negotiation delegation.A central conclusion from this investigation is that the representatives of the Tenant Association generally are satisfied with the democracy model used in the organisation, despite awareness of the fact that there are some failures with representation amongst younger people, women and immigrants. Also, they suggest that the model with representative democracy is by all means the most useful because of its arrangement and efficiency in decision making processes.The policies of the Tenant Association, considering distribution of power and participation between elected representatives and employees, are legitimated by the negotiation delegates. However, there is obvious discrepancy in the look upon their respective tasks between the delegates and the chief negotiators.One can recognise the development of democracy that is called New Public Management in this survey.
Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm
Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years. Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed. Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.
Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks
Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.
Orsaker till kalvningssvårigheter och dödfödslar hos SLB och SRB
Difficult calvings and stillborn calves are costly for the producer and lowering these frequencies can decrease the costs for the dairy operation. Each calving in the herd is registered by the farmer and stored in a central database. The information is used to monitor the level of calving-difficulties and stillborn calves in the herd and nationally. Monitoring of these registrations is important to detect possible changes. Breeding-value prediction for calving traits is based on the calving information in the database.
Trådlöst bredband -bör trådlösa nätverk tillhandahållas kollektivt?
Bredband har de senaste åren gått från att vara en ovanlig företeelse till att i Sverige närmast ses som en mänsklig rättighet. En teknik som ger många individer tillgång till IT-infrastrukur med hög överföringskapacitet är trådlösa nätverk av typerna WiFi och WiMax. I uppsatsen konstateras att ett marknadsmisslyckande kan förekomma på privata marknader för trådlöst bredband. Detta marknadsmisslyckande analyseras utifrån teorier om externa effekter och kollektiva varor. De positiva externa effekter som trådlösa nätverk genererar ger varan drag av kollektivitet.
Framtidens driftcentral : En analys av den framtida driften av ett svenskt elna?t
Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.
Level-Up! : En uppsats om spelutvecklares väg till ökad autonomi
Vår uppsats fokuserar på data- och tvspelsbranschen med en inriktning på relationerna mellan spelutvecklare och spelutgivare. Bakgrunden till uppsatsen och studien bygger på att maktbalansen mellan spelutvecklare och spelutgivaren faller i favör för spelutgivaren som ofta kontrollerar både finansiering och distribution av en spelproduktion. Detta skapar en situation där spelutvecklaren, som står för den skapande delen av en spelproduktion, har liten till ingen kontroll över sin egen verksamhet. Denna balans håller på att förändras genom uppkomsten av nya finansierings- och distributionsalternativ som tillåter spelutvecklaren att förbigå spelutgivarens inblandning i spelproduktionen. I vår uppsats har vi valt att undersöka hur folkfinansiering, digital distribution och mun till mun-marknadsföring påverkar spelutvecklares autonomi.
Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.
Distribution Av Pejlbäringar Över IP-nät
The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

Behöver tillväxten en stad? Om Dublin som politisk arena, aktör och tillväxtmotor
This thesis intends to examine the role of the city, Dublin, in the Irish economic growth during the 1990s. It is a case study where Dublin is compared with current theories on post modern cities as growth machines and increasingly prominent actors in the global context. The study has an interdisciplinary approach but focuses on political science issues such as power distribution, global-local governance and local political organisation. It is a theory driven study that also intends to add aspects to the understanding of the cities of our time. I argue that Dublin has faced a lot of changes during the last decades in accordance with the post modern city.
Utvärdering av Skogens Dag i Borås 2005 evenemanget som informationskanal
The purpose of this thesis is to examine Skogsstyrelsens event Skogens Dag as an information channel by looking at information use and information behaviour during the communication process of the event. This is done by examining the aims of Skogsstyrelsens information distribution during the event in relation to its outcomes. The evaluation is focused on long term effects on the target group and it is restricted to Skogens Dag in Borås 2005. The question this thesis intends to answer is: How does the event Skogens Dag function as a tool for information distribution? The theoretical background gives an account of the communication process as well as the relevant aspects of marketing, social marketing, campaigns and public relations, as these are communication attempts that can use an event as a medium.
Modellering av försäkringsdata med normal invers gaussisk (NIG)-fördelning
Utbetalningsbelopp för skadeersättning studeras. Datamaterialet uppvisar skevheter och 'tjocka svansar' vilket motiverar att modellera med en mer flexibel fördelning än normalfördelning. I detta arbete undersöks om NIG (normal invers gaussisk) fördelning passar för det..
