Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.

Studies of modern communication media such as Cell Phones and so called Instant Messengers are popular today. This study focused on these modern techniques, focused on parents as a target group and on what is important for them in everyday communication.By exploratory using three focus groups it became clear that the children, and the link to them was the absolute most important thing for the parents. It became clear that this link to a great extent today exists through the mobile phone.In a following study a Mobile Instant Messenger called My Friends was introduced. It was used by two families during two weeks to see how it would change the communication within the family. The focus was to see how problems with availability were handled, it turned out that:My friends had a more obvious way of indicating availability than the Cell Phone had.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Sänkgnistning är en icketraditionell bearbetningsmetod som i Sverige används av både små och stora verkstadsföretag. Metoden används i syfte att framställa geometriskt komplexa detaljer, främst ur härdat stål. Dessa detaljer används vanligtvis som produktionsmedel. Detta innebär att kunderna använder en eller fler detaljer, som producerats med sänkgnistning som verktyg, för att producera egna produkter. Vanligt förekommande är att kunder använder sänkgnistdetaljen som verktyg för formsprutning vilket ofta genererar många produkter per sänkgnistdetalj.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.

När man väljer att analysera företag, finns det flera olika värderingsmodeller att använda.En av dessa är Piotroskis F-score. Denna modell har mestadels tidigare använts för att analysera företag på den amerikanska marknaden. Nu vill författarna undersöka hur tillämpbar modellen är på den svenska aktiemarknaden och dessutom kombinera denna modell med en Magic Sixes värdering för att öka dess precision.Syftet med denna studie är att undersöka om F-score i samarbete med Magic Sixes kan generera överavkastning och överträffa den svenska aktiemarknaden.Författarna har genomfört en kvantitativ studie med en deduktiv ansats. Data har samlats in med hjälp av databasen Orbis och Dagens Industri. Författarna har upprättat identiska listor för att beräkna företagens F-score och Magic Sixes.

Det har gjorts mycket forskning kring Positioneringssystem för inomhusbruk då många applikationer och tjänster ärberoende eller kan förbättras av det. Trots detta finns idag ingen standard för hur positionering inomhus ska fungera.För de flesta utomhusmiljöer kan en modern mobiltelefons position erhållas med ett par meters precision via GPS. I eninomhusmiljö sjunker signalen drastiskt och en precis position är svår att uppskatta. En väl etablerad teknik är Wi-Fioch kan med fördel användas då de flesta inomhusmiljöer idag redan har Wi-Fi accesspunkter installerade. Då enmottagare erhåller en signal från en accesspunkt kan distansen dem emellan uppskattas för att sedan uppskattapositionen med den matematiska tillämpningen trilateration.

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

A Quick Test (AQT) Färg och Form är ett test av snabb automatiserad benämning avsett att detektera kognitiva störningar. Det består av tre delar som var och en utgörs av 40 visuella stimuli som skall benämnas så snabbt som möjligt. Tidigare studier har indikerat att AQT skiljer personer med Alzheimers sjukdom från friska kontroller med högre precision än det ofta använda Mini-Mental-Testet (MMT). I denna studie undersöktes för första gången om AQT-resultat kunde predicera diagnosen hos en konsekutiv serie patienter vid en minnesklinik samt relationen mellan AQT-resultat och biomarkörer (likvorproteiner) för neurodegenerativ sjukdom. 492 svarsblanketter från AQT Färg och Form analyserades och diagnostisk prediktion samt korrelation med nivån av likvorproteiner fastställdes för de 374 första patienterna i serien.
