I en värld där kraven på flexibilitet, säkerhet och hårdvaruoptimering är nyckelfaktorer när det kommer till att välja IT-miljöer för företag blir virtuella skrivbord mer och mer poulära. Med dessa miljöer finns det också problem när det kommer till användarupplevelsen om nätverket ifråga inte kan uppfylla de krav som ett sådant system ställer. I detta arbete undersöks implikationerna vissa nätverksvariabler kan ha för en Virtual Desktop-infrastruktur, VDI. För att belysa dessa problem har två tester utförts på en VDI miljö. Det första testet gick ut på att mäta latensen då skrivbordsmiljön renderades för klienten från virtualiseringsservern vid olika nätverksdiamterar.

The aim of this study was to describe how persons with Whiplash associated disorder experience how the pain affects them in their daily life. The design of the study was descriptive with qualitative, individual interviews, questionnaire with background facts of the examination group, and diary notes from persons with pain of WAD. Method for selection was convenience. Through contact with the association of whiplash group in a county in middle of Sweden, the majority of the examination group for the study was found. Five persons where given information about the study, one of them choose not to take part of the study, and one of the persons did not complete the study.

Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.

Axelopererade personer har svårt att röra sig under några veckor efter operationen. Den som bor i glesbygden och blir opererad i axeln eller armen måste regelbundet åka långa sträckor för att besöka sjukvården och bli undersökt. Frågan är om det går att minska dessa bilturer och samtidigt behålla vårdkvaliteten? Man har kunnat reducera patienternas resande till och från sjukvården med hjälp av en enkel videokonferensanläggning som patienten får låna hem. Med denna utrustning kan patienten upprätta videomöten med vårdpersonalen istället för att åka till sjukvården.

This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

Att utforma interaktiva TV-tjänster skiljer sig på flera sätt från att designa för webb eller för vanliga PC-tillämpningar. Faktorer som lägre bildupplösning, längre avstånd mellan användare och skärm, och inte minst användandet av fjärrkontroll istället för tangentbord och mus gör att villkoren ser annorlunda ut än för PC-tillämpningar. I detta arbete beskrivs hur en videobutik för en set-top-box för digital-TV utformas via iterativ hifi-prototypning och utvärdering. Lärdomarna är tillämpbara på andra interaktiva TV-tillämpningar..

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

This paper studies the philosopher Ludwig Wittgenstein during his years (1920?26) as an elementary school teacher in remote Niederösterreich, Austria. The paper gives a survey of his life, and also a brief account of three of his main works: Tractatus Logico-Philosophicus, Philosophical Investigations and Remarks on the Foundations of Mathematics. Attention is given to his alphabetical word list, Wörterbuch für Volksschulen, published for educational use in elementary schools. The study is focused on Wittgenstein?s educational practise, and establishes a connection between his experience as a teacher and his late philosophy..

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..

En typ av beskattningsregler som finns i de flesta av EU:s medlemsstater är Controlled Foreign Corporation(CFC)-lagstiftning. CFC-lagstiftningen reglerar beskattning av delägare i utländska juridiska personer med lågbeskattade inkomster. Den svenska CFC-lagstiftning är bl.a. till för att motverka och hindra internationell skatteflykt. Det kan t.ex.

In the fragmented network economy of toady remote work for creative designers becomes mor eand more prevalent. This is good for a number of reasons. Mainly, creative designers can find work inside and outside of their region irrespective of where they choose to live. However, competing for jobs in a global market is harder, and the online presence of the creatives becomes their main shopping window. We have conducted a study, interviewing digital creatives in Västerbotten.

This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.

A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.
