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.

The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.

The aim of this study was to investigate whether there is a correlation between birth order, academic performance and need for achievement. 166 students from Alvesta Gymnasium/ High school and Växjö Fria Gymnasium/ High school participated in the study. The result showed a significant correlation between birth order and study result, but unlike previous studies this study showed that it was the youngest siblings that had the best academic performance. Furthermore, a significant correlation between academic performance and need for achievement was found, also that higher need for achievement results in higher academic performance. The study also showed that there is a significant correlation between birth order and need for achievement, and it is the youngest children that have the highest need for achievement.

In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.
