Forces of innovation alter the course of many industries. Currently there is a restructuring of the Swedish energy sector due to deregulation. This in combination with advanced technologies generates an innovative and a highly changeable environment. The result is differentiation of services and products. New actors are emerging and corporations grow larger.

The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

Research about social support and social networks has mostly concerned the impact on a person?s wellbeing and health. However an aspect largely neglected is how social support within the social networks can affect the process of giving up a drug abuse. The purpose of this paper is to contribute to a better understanding of what role the social support within different relationships can have on the process of giving up drug abuse. Furthermore the aim is to examine how a self-help group can provide social support in the transitional period after leaving a drug abuse.

The purpose of this project was to investigate if retention of polar compounds that are given to treat tuberculosis, diabetes, inflammatory bowel disease and childhood leukemia could be obtained with HILIC separation. By varying different parameters for different types of columns the compounds were analyzed with the aim of finding guidelines for future method optimizations. To perform these analyzes three different columns were tested ? ZIC-HILIC (silica-based with zwitterions), ZIC-pHILIC (polymer-based with zwitterions) and XBridge Amide (amide functions). The results were evaluated with selected quality measures.

Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.

The aim of this literature review was to discern which legislations and regulations related to animal welfare that comprises reindeer and their significance in reindeer husbandry. The Swedish Animal Welfare Act (1988:534) was enacted July 1, 1988 and its main purpose is to ensure a good animal health and environment. Animals that live in a good environment with good health is considered to have good welfare, which can be described as an individual's condition in relation to its surroundings. Reindeer herding is an extensive form without daily management. In reindeer husbandry there are eight specific seasons over the year and reindeer are handled as they migrates between pastures, get earmarks, are sorted for transport and slaughter.

The aim of this essay is to investigate whether the role of the teacher and the teaching in the classroom is affected when the Ipad is introduced in an one-to-one situation, and if so how these effects occur. Previous research show that the introduction of new technology in education offers hope of a more effective way of learning but that this at the same time leads to challenges for traditional ways of teaching and traditional views on knowledge (Säljö & Linderoth (red.) 2009, Erixon (red.) 2014).The method used is a qualitative interview in combination with observations used as a complement to the interviews. Four teachers working on an upper secondary school have been interviewed and one lesson in English taught as a foreign language and one lesson in social science have been observed.The results show that the use of Ipad changes how the teachers relate to and use the teaching material, as all material can be gathered in the Ipad and accessed at all times and can also be shared with the pupils. The Ipad also makes it easier for the teachers to offer pupils individual instructions which the teachers view as positive. In addition, the Ipad enables a change in regards to the pupils as they switch from being users to becoming producers in the use of the Ipad which in the teachers? opinions offers more profound ways of learning..

The purpose of this master?s thesis is to examine how some university students, who are using the libraries extensively, use and experience the public and the university library and what they expect from the two different library types. I also compare their expectations with the different tasks and aims of the two library types. To answer this I have interviewed seven students at the department of history of literature at Göteborg University. I have also studied some literature and research related to this subject, for example user studies about students and libraries and the information behaviour of distance students.

Hepatitis E virus, HEV, is a frequent causative agent behind, especially waterborne, infections in developing countries such as India. However, during the last years the number of non-travel-associated infections in industrialised countries, for example US, Germany and Sweden, has increased. The symptoms vary from mild with nausea to icterus and it can even be lethal. There are four different genotypes of HEV and many studies consider HEV infection to be a zoonosis. Scientists have by using phylogenetic analyses found great genetic similarity between strains isolated from humans, pigs and food, such as pork and liver, especially among viruses belonging to genotype 3.

VEP, visual evoked potential is an electrophysiologic test that can be used for evaluating the higher visual pathways. The aim of this study was to investigate if it is possible to adapt this method to horses. This method could have a clinical use in addition to the existing diagnostic methods that are available to evaluate vision in horses. Firstly, this study contains a summary of relevant studies done on animals and, secondly, an experimental part where the possibility of recording VEP in nonsedated and sedated horses is investigated and where to position the recording electrode to obtain the best results. Our results show that it is possible to record VEP in horses in a clinical setting. VEP was best recorded in the sedated horse to avoid movement artifacts and other disturbances.

This thesis which is about working with mathematics teaching has no effect/impact on performance and understanding of pupils. The study is intended to gain insight on working in mathematics education which has an impact on performance and understanding of students who are ethnically Swedish and foreign ethnic. In order to compare the ethnic Swedish and foreign students of ethnic understanding, I judged from their performance on the tests taken in year three. The qualitative approach permeated the work, both interviews and observations which were included in the survey. The qualitative study was chosen to get an understanding of how mathematics teaching is conducted in two different areas.

The number of students who finished special upper secondary school for pupils with intellectual disabilities without an employment has drastically decreased over the last decades. The purpose of this paper is to increase the knowledge of how career counselors at special upper secondary schools collaborate with the Employment Service, and how the special upper secondary school prepares their pupils for working life. The collection of data started with a national questionnaire survey which was directed to career counselors at schools.The result shows that the collaboration appears foremost in the pupils last year in special upper secondary school, and that the special upper secondary schools do not use the Employment Service's assistance to any great extent. In addition, the collaborative process consists of both inhibiting and promoting factors.The results also indicates that the collaboration between the special upper secondary schools and the local labor market can be developed more for the pupils to gain experience from working life..

The consociational democracy model in Macedonia, which came out from a warcrisis and a peace agreement from 2001, in addition, putting an end to the violent conflict, actually admits the division of the society along the ethnic lines. Paradoxically, there is an attempt to bridge the ethnic gap with this model. As a result, the consociational democracy model holds solutions that can be abused if somebody misuses its power and desires to disintegrate the country. The future development depends therefore on the moderate attitude of the citizens, and first and foremost, on the political elites and their commitment to the values of democracy and human rights instead of their nationalistic goals. Furthermore, thepresent democratic consolidation in Macedonia is established on the execution of the peace agreement and the improved effectiveness of the institutions.

The essay is a discourse analysis of the media's attitudes toward computing. The aim is to compare what the media is really saying about the usage of tablets, computers and compare it to what the research is saying. In addition, it examines what the media says about socialization. We analyze the newspapers Dagens Nyheter and Expressen and will first compare these two together and see what attitudes that emerge, and then seek similarities and differences with the previous research and theories including socialization learning, attitudes and consumption. Conclusions we can draw is that Expressen has a more negative attitude towards the use of computers while the Dagens Nyheter has a more positive attitude, but is also more objective to what they write about.

The EU- citizenship was established in the Maastricht Treaty in 1993. This citizenship involves rights to free movement, election rights to the European Parliament, diplomatic protection and the right to petition to the Ombudsman. In my analysis I discuss the implications of the EU- citizenship for the individual. The development and legal status of the union citizenship is examined in order to give a general understanding of the implications. In addition, I conduct a case study concerning the EU- citizenship's impact on workers rights.
