OpenGL is a standard API that is used to manage 3D graphics on desktop computers. Although OpenGL is independent of customized hardware it?s not suitable for all kinds of devices. Therefore both OpenGL ES andWebGL was created. These can be viewed as subsets of OpenGL.

This thesis work aims to describe the prerequisites for a distributed treatment platform for real-time sharing of rounds performed by paediatric oncologists. The work started during the autumn 2004 and is directly aimed at improving the situation for the thirty or so specialist treating children with cancer. The work is not limited to the description of such a platform but also to select suitable software and hardware for the implementation of the platform and further more to coordinate the implementation. The production of several documents describing the platform is also part of this work. The work successfully led to the implementation of such a platform as described in the published article Barnradioterapi på distans Kristenssen et.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, two-dimensional, three-dimensional and many more.The goal with this thesis is to create a fast and low effect version of two-dimensional IDCT algorithm, where techniques as multiple-constant multiplication and subexpression sharing plus bit-serial and bit-parallel arithmetic are used.The result is a hardware implementation with power consumption at 19,56 mW..

Recent developments suggest that private and public companies are moving towards a more service-oriented business. Service orientation means that hardware is often sold in packages with service agreements, which makes the investment more difficult to assess. The challenges that arise will be to assess the value of the overall package, the information needed to make informed decisions and the operational requirements in combination of hardware, software, support agreements, training and more. The paper therefore aims to examine how decision makers can evaluate the benefits of these investments and obtain a stronger base to make better decisions. There is within the area of radiology in the region of Västra Götaland a pronounced need for a better flow of information regarding medical equipment and related service agreements.

At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

I takt med att inflödet av studenter minskar ifrån gymnasieskolan är det viktigt för högskolor och universitet att erbjuda en mer flexibel utbildning. I datalogikurser inom nätverks- & systemadministration där studenten ska kunna få praktisk erfarenhet genom laborationer finns det vissa krav på laborationsmiljön om utbildningen skulle erbjudas på distans. Studenten måste då kunna installera nya operativsystem fritt inom kursens ramar i en virtuell miljö.För att denna variant av laborationsmiljö ska vara möjlig att erbjuda, krävs det mjukvara där det för studenterna fritt går att installera operativsystem med stor flexibilitet i en virtuell miljö. En studie behövs som utreder vilken funktionalitet som är relevant och vad som kommer krävas av de mjukvaror som påträffats användbara för laborationsmiljöer inom främst systemadministration.Detta arbete har jämfört funktionalitet och prestanda hos mjukvarorna VMWare vSphere 5 med vCenter Server mot Red Hat Virtualization 3. Resultatet påvisar i stort mycket likvärdig prestanda men VMWare har betydligt mer funktioner som kan vara användbara i miljön.

The objective for this study was to acquire a greater insight if children with concentration difficulties are assisted by outdoor education in the traditional teaching. With the use of a qualitative methodology four teachers were interviewed. The outcome gave evidence for that the teachers thought that outdoor education has a positive outcome for children with concentrations difficulties. The findings were divided into three key categories: the teacher?s reflections about outdoor education, outdoor education for children with difficulties in concentration and if there was any difference in how the children behaved indoors after having educations outdoors..

Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

It appears from today's debate about the quality of social work and addiction treatment that largely focuses on the impact of recent various interventions in the hope of being able to alter social work's role in society and also the organizational structure. The debate points to a part of the 1970s social welfare debate. Today's aspirations to establish an evidence-based practice can hardly be expected to solve the social services basic dilemmas is that it always have to do something, despite the many times you cannot get clear instructions on which funds should be used by law or science. Even if you follow the rules and practices based on scientific studies should the importance of various key initiatives to remedy deficiencies in social service work with addicts in large part depend on how, in these initiatives define the term "evidence-based practice" and what steps will be indicated for to develop practice. My starting point was to explore how evidence-based social work in connection with medication-assisted treatment for opiate addiction look, which evidence-based interventions Social Services currently uses in connection with medication-assisted treatment for opiate addiction, as well as how to work with it in the ordinary course of business. The study showed that social services have become better at using these methods in recent years and that today there are more tools available than before.

Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..
