Jaktprov hos brittiska stående fågelhundar
In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures.
Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

ISO 14001 : Från ledningsbeslut till certifiering
Tidigare ombesörjde organisationen karriär och karriärutveckling för den anställde och karriärkontraktet byggde på livslånga anställningar. Det nya karriärkontraktet bygger istället på en så kallad proteisk karriär (Hall, 1996), vilket utmärks av att individen ser sig själv som ansvarig för och drivande av sin karriär, att egna värderingar får styra samt att psykologisk utveckling är främsta mål. Studiens frågeställning var att undersöka om personlighetsfaktorer i termer av self-efficacy, självkänsla, locus of control samt neuroticism kan predicera proteiska karriärattityder. I studien användes kvantitativ metod och en enkätundersökning genomfördes på studenter. Korrelationsberäkningar visade att samliga personlighetsfaktorer samt proteiska karriärattityder var korrelerade.
Generationsskräpsamling med explicit kontroll av hårdvarucache
This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..
SELF CONTROL
SELF CONTROL är ett undersökande examensarbete i textildesign. Med en textil hantverksmetod undersöker jag mötet mellan kontroll, tidsåtgång och material. Detta med utgångspunkt i en feministisk diskurs. Jag ser kontroll som något som exkluderar, censurerar och begränsar möjliga uttryck inom textilt hantverk på samma sätt som kvinnokroppen kontrolleras i ett patriarkat. Jag har använt mig utav en performativ och repetitiv metod som aktivt har gått ut på att bryta mot föreställningar om hur hantverket ska utföras.
Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller
Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.
Ett samhällsengagemang som Skapar Shared Value - En studie om hållbarhetsstyrning och Creating Shared Value i en svensk kontext
This study investigates the corporate sustainability activity, linked to the company's core business, which is a relatively unexplored field in a Swedish context. The study examines how the organization has used management control for its sustainability activity within two social initiatives; and whether these initiatives have generated value for the organization and involved stakeholders. Management control of social initiatives are examined within the theoretical framework of The Sustainable Balanced Scorecard and the organization's value creation contributions are outlined in accordance with a definition of the concept of Creating Shared Value. The method used for the implementation of the study is a qualitative study, embodied in an illustrative case study of a large Swedish company operating within financial sector. The empirical data was collected through 12 in-depth interviews with representative interviewees within the organization and with other stakeholders involved in the company's social initiatives.
Implementation of an FFT algorithm using a soft processor core
This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..
Processdatorsystem för tryckreglering
The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..

This study focuses on the internal marketing and how it affects the complaints by companies? communication control. Our purpose with this subject is to increase the understanding of which components affects the relation between internal marketing, communication control and complaints. We have chosen the subject, internal marketing because it caught our interest in an earlier course. On the basis of the literature of costumer complaint there have not been so much research about it and that is why we have chosen this perspective on internal marketing.This study is based on a qualitative approach.
Evaluation of the animal welfare work performed by the licensing committees and a proposal on how to establish an enhanced animal welfare assurance program for the Swedish Trotting Association
According to the basic values of the Swedish Trotting Association the horse and its welfare should always be held in highest consideration. One part of the animal welfare work in the organization is to ensure good horse management practices by controlling all active trainers through the local licensing committees situated at the Swedish racetracks. The Swedish Board of Agriculture stated that high quality animal welfare assurance programs used by the industry organizations can be used in the risk assessment of the official animal welfare control to make the official control work more effective and the ambition of the Swedish Trotting Association is to establish an animal welfare assurance program which may be approved by the Swedish Board of Agriculture. Racehorses are exposed to welfare hazards both in their management as well as during training and racing and factors like handling, training, feedstuff, stable environment, medication and the possibility to express natural behavior all affect the welfare of the horses.
The aim of the project is to investigate and evaluate the animal welfare work performed by the licensing committees and to give advice on how to improve the industry?s animal welfare control.
