Voice-over-IP (VoIP) är en samling teknologier för transport av digitaliserat tal över IP-nätverk. Den mest kända applikationen för VoIP-teknik är internettelefoni. Processorer och gränssnittskretsar som kan realisera ett VoIP-system har utvärderats för användning i produkter med låga produktionsvolymer spridda över flera år. Komponentkostnad, utvecklingskostnad och även hur länge komponenterna kommer att tillverkas är viktiga faktorer att ta hänsyn till. Resultatet av studien är att generella signalprocessorer av den nya generationen, med arkitekturförbättringar som ger mer microcontrolleregenskaper, är de bästa kandidaterna.

It is very important to gain knowledge and better understanding for people with dyslexia in other words people with reading and writing difficulties. I have therefore chosen to learn more about this subject. In my study, I have focused on adult people with dyslexia.This study is about four student teachers different experiences of dyslexia during their studies. The aim is to find out how the student teachers diagnosis has affected their education situations of these areas; the need for help, environmental significance, management of the different reading and writing tasks in their education and the advantages they believe there is in their future work as teachers.As a research method I have used qualitative research and qualitative interviews. The participants in this study are four female persons in the ages of 23 to 25 years old.The results showed that the need for assistive help devices varied because of the student teachers different experiences.

The aim of the study is to learn more about the way preschool teachers work with Information and Communication Technology(ICT). More specifically, this study aims to explore how preschool teachers describe their experience of ICT, the conditions and opportunities to work with ICT, and their own knowledge and competence in the use of digital tools with preschool children. The research method consists of interviews with preschool teachers and observations at five municipal preschools in Stockholm as well as an analysis of the relevant passages in the Curriculum for the Preschool and the Curriculum of Stockholm city. This study shows that there seems to be great variation in the amount of ICT tools present in preschools. Preschool teachers expect a lot from ICT, and the improvements that it can make on their work.

The European Union is a self proclaimed leader in the field of climate change and has a common target for reductions of greenhouse gas emissions. In spite of this, there are great differences between the member states capacity and dedication to the cause of implementing the Unions climate policy and reduce their emissions. The purpose of this thesis is to contribute to an understanding of how different European states construct their identity in the context of climate change mitigation. By analyzing national documents from three European states and using tools deriving from discourse analysis, I aim to illuminate differences and similarities in their rhetoric. The result is that due to the states relationship to the European Union and the United Nations, there are great similarities in the way they construct mitigation and their identity.

The aim of my study is to look at two specific schools and their work with Internet in the classroom and compare their work to what experts say about how you should educate. The study focuses on how teachers guide the students to be critical to the information they encounter on the internet. What do the experts say? How should the teachers work with Internet in the classroom? What do the teachers say about their work with Internet? What do the teachers say regarding children and the Internet?  To answer these questions I have interviewed two teachers from different schools, which had classes with children 6 to 8 years old. The schools are very different from each other concerning investment on Internet devices in the classroom.

Background: Health economic evaluations are becoming an increasingly important means of analysing which care alternative resource utilisation is the most cost effective. It is a new topic in the medical device industry that causes much uncertainty and unstructured use of the actors involved.Study questions: Why is it difficult to develop, implement and disseminate this standardized health economic evaluation models in medical technology? Is there a possibility to standardize health economic evaluations within the medical device industry?Purpose: The purpose of this study is to investigate the standardization issues for health economic evaluations within the medical device industry.Method: A qualitative approach was used in the form of interviews with five actors that are active or have a connection to the medical device industry. The data collection consists of journals, reports, Internet searches and literature among other things.Conclusion: It is possible to standardize, but with certain restrictions such as the county council's budget, influence of industry-specific factors, lack of knowledge and the important interaction between actors..

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

This thesis is a comparative analysis of language policy in the Post-Soviet states Ukraine and Kazakhstan, wherein the states are seen as rational actors using language as an instrument in the nation-building process. With a take-off point in an underframe of theories on the nation, national identity, instrumentalism, power and the particular role of language in the nation-building process, this thesis shows that language is a key instrument used by the two states.The Ukrainian and Kazakhian language policies create and put across a certain image of the nation, by emphasising the titular languages as symbols of the new states. The line of argument in the language policy is a balance act between large-scale promotion of titular languages and a careful and inclusive attitude towards the Russian language. The biggest differences are that Ukraine, compared to Kazakhstan, has a more comprehensive and consequent language policy with a deeply rooted historic rhetoric. The most obvious instruments of the states in language policy is censuses, corpus-planning and the state choosing one official language..

Cancer is one of the most feared diseases in veterinary medicine today, and the incidence is higher than ever due to the fact that our companion animals live longer then they did ten to twenty years ago. Cancer is also one of the most common causes of mortality in older companion animals. This literature review will be about two of the currently most common form of cancer treatment of companion animals in Swedish animal hospitals, chemotherapy and radiation therapy. There will also be a section of general nursing care for cancer patients. The section of chemotherapy will describe the indications for choosing chemotherapy, the way to administrate chemotherapeutic drugs, describe specific chemotherapeutic drugs, potential side effects of chemotherapy, and how to handle and store chemotherapeutic drugs safely. The section of radiation therapy will describe the current devices for delivering radiation therapy, describe the indications for choosing radiation therapy and describe potential side effects that radiation therapy may cause.

This essay is about publishing on the Internet and aims to understand the differences between publishing information on the webpage Wikipedia (Swedish version) in contrast to other information pages on the Internet, for example blog, discussion pages, homepages etcetera. The study is based upon an article which described that 90% of the information publishers at Wikipedia belongs to a small elite of white, western, well educated men between the age of thirty to thirtythree. This study examines why people who does not belong to this heteronormativity publish information in other Internet places but not at Wikipedia.Wikipedia is an open source site, where anyone can publish and are even encouraged to do so and is often described as an utopian dream of the digital democracy, so why don´t people express themselves on Wikipedia? The method is based on two discussion groups, which are compared and analyzed. The study is based upon theoretical competence within feminist theory and conceptions such as intersectionality, heteronormativity and digital divide as well as theories about digital devices and social order.

Uppsatsen handlar om retoriken i tv-spel. I tv-spelsforskningen pågår en debatt mellan ludologin och narratologin där ludologin menar att spel ska ses som spel och inget annat ? exempelvis som en fotbollsmatch där spelet självt är det huvudsakliga innehållet och där ingen frågar efter ytterligare mening. Narratologin menar att spel i grunden är berättande eller bär på berättande drag ? att en fotbollsmatch följer en överskådlig dramaturgi och berättande mönster.

What happens when one moves about in the city? In this essay I will explore how we through our movements create our own temporal cities. I base my investigation on Michel de Certeau's theories from his book The Practice of Everyday Life vol 1. De Certeau believes that by just walking in the city ? a mostly unconscious and for many trivial activity ? you write it, creating different types of spaces that can be understood using linguistic terms.In my essay, I develop de Certeau's theories about ordinary activities by applying them to two less ordinary ? and between themselves quite different ? spatial practices:  fare evasion on public transportation (plankning) and the urban activity of parkour.

Enligt kommunikationsmyndigheten PTS finns det cirka 10miljoner mobiltelefonabonnemang endast i Sverige. Telefonerna innehåller operativsystem där det tillåts mängder av olika sorters program.

The usage possibilities of mobile platforms and smart phones are increasing rapidly as they provide support for better processors, sensors and communications capabilities. This has for many companies resulted in an increased interest to explore the possibilities of mobile platforms and how they can be integrated in various business areas. As the usage of mobile platforms in industrial applications is a new area, it is difficult for companies to estimate their potential, and what contributions the different platforms can give.This master thesis investigates the possibilities and limitations for the consultant firm Combitech when integrating mobile platforms and handheld devices in industrial applications. This is accomplished through a comparison between the platforms and by considering the possible areas of use for the mobile platforms based on experiences from companies and research in the area.For a company with the intent to deliver services that use mobile platforms, it is important to be able to combine expertise and resources to effectively attract customers. The mobile platforms will, if applied right, give great possibilities in industrial applications as a cost-effective alternative for both hardware and software solutions for businesses, which provides an opportunity to sell services to both established and new clients.
