This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

The objective of this study was to investigate the attitude towards African swine fever (ASF) primarily among smallholder pig farmers but also among other actors along the pork value chain in Gulu district, Uganda. More specifically, the study aimed to investigate the specific challenges facing both farmers and other members of the pork value chain using participatory epidemiology (PE). ASF is a feared viral disease of pigs associated with high mortality, which is endemic in many parts of Africa. The recent history of Gulu district in Northern Uganda can be described as turbulent and the human population has suffered during decades of war and civil unrest. Pig keeping is considered a potential opportunity for business as well as a way of providing more animal protein in the diet. However, this is threatened by ASF as farmers can lose entire herds due to the disease. This study can confirm some previously known factors and risk activities such as the free range system of pigs and movement of pigs and pork during ongoing outbreaks, which make disease control difficult.

AbstractCompanies in the Swedish process industry has for a long time spent a lot of capital in high-tech development, which have given them increased ability to compete with high quality and excellent technical knowledge, which has given them greater opportunities to grow on the market. But it?s not enough to achieve success with new products and service; it must also be consistent what market wants and preferably something exceptional. The purpose of this study was to determine the factors that are predominantly success factors and how they may affect the sales target of a new product, in this case Frövi White. Another objective of the study was to examine how Korsnäs Frövi communicates and transforms information as requests and demands from customers into refined material. To obtain relevant information to the study several interviews with respondents from most of the value chain in Korsnäs Frövi has been carry out.

This thesis aims to examine how teachers who teach the Swedish subject, uses film in their education. The survey was given to 30 of these teachers in Nykoping, half which are working in junior high schools, and half which are working in high schools. One importantcondition to this works implementation, is the existence of the widen text concept that points to that all media is a concept that can be read and analysed. This is the attitude that The National Agency for Education aims at in different govern documents. The National Agency for education also request teachers to give the students tools to the media literacy that the society demands.

I det här arbetet undersöks och jämförs två olika sökalgoritmer när de används för implementation av AI-spelare till brädspelet Pentago. De två algoritmerna som användes var alfa-betabeskärning och en nyare algoritm som kombinerar genetiska algoritmer och minimax, kallad genetisk minimax. Utvärderingen av resultaten visar att alfa-betabeskärning passar bättre vid implementation av en AI till Pentago än genetisk minimax. Alfa-betabeskärning med ytterligare optimeringar har potential att lämpa sig väldigt väl för implementation av spelare till Pentago. Ytterligare visar resultaten att genetisk minimax inte är en passande algoritm för AI till Pentago.

This study was performed to investigate the bacteriological quality of French cheeses made from raw milk. Fifty cheeses of this type were purchased from Swedish retail premises. The methods described by the Nordic Committee on Food Analysis (NMKL) were used to determine the number of Enterobacteriaceae, presumptive Escherichia coli, coagulase positive staphylococci and Listeria monocytogenes. In 32 cheeses (64%) the number of bacteria mentioned above exceeded the determined maximum value. Thirty samples (60%) showed high counts of Enterobacteriaceae.

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

AbstractThe purpose of this essay was to examine how young people who are about to graduate from high school define and value their future. We also wanted to se which emotions they associate with their future and what or who influences them in their choices in life.The questions for our study were:What does it mean for these youths to become an adult?What images do they have of future education, profession and unemployment?What or who influences the picture they have of their future?What kind of attitude do they have towards the future?We approached the research with a qualitative method and interviewed ten youths in high school. Our conclusion was that the youths had an ambivalent attitude towards becoming adults; it was scary and yet exciting. The youths had the impression that education was important in order get a good job and to avoid unemployment.

The objective of this study has been to examine which significant values are of importance in the telecom sector today, and in a continuing perspective yet to be. To ensure the factors of relevance in the study, we have identified three purposes: - Our first purpose is to clarify the eminent values in the competitive market of the mobile phone operators today, and the reason for its importance.- The second purpose is to understand the function of the brand regarding to value creation and loyalty in the sector of mobile phone operators.- The third purpose is to explore the potential approaches for mobile phone operators to increase value.In this study, our approach has been a qualitative methodology by conducting seven interviews with respondents related to the telecommunication sector.As a result of the process, we find the need to divide the concept of value into two dimensions, which we entitle organizational related values and customer related values. We have found the values related to the characteristics of the market in aspects of its infrastructural features but also in regards to the homogenous core service.Our findings in the empirical data with support to our theoretical frame of reference, is the current highly important organizational related value of constant high result quality (well-functional technological aspect), and the value enhancer by a low price; the strategy of bundling also results in higher value. This result in customer related values that perceives as safeness, availableness and convenience. The brands are a significant source of customer related values with identity value, image value and assuredness. A continued advancement in process quality and individualization will imply greater customer related values of closeness, freedom and flexibility. .

We have seen a revolution in the area of communication on a worldwide scale. We begin talking about terms as globalisation, integration and deregulation of the financial market. Companies have been tax planning for decades, the questions is if Internet has made an increase of companies than uses tax planning and which roll Internet plays. It is hard to really pinpoint all the effects of the Internet because of the relatively new area of research. This thesis will take various factors under study such as globalisation, development of the offshore industry and the fight against harmful taxation by the OECD and other organisations in order to describe the effects of Internet.

Extensively kept animals for meat production have the right to live in a good environment. Cattle (Bos Taurus) as social animals live in small herds in the wild. When holding animals extensively new problems have arisen regarding human ? animal interactions. One welfare problem is to be able to come close enough to the animals to investigate their health condition.

Stockholm har inför 2050 satt upp ett mål om att bli koldioxidfritt. I strävan mot detta söker man utvinna energi med förnybara metoder och ett alternativ för elproduktion inom stadskärnan skulle kunna vara solceller. Solceller är en teknik som genom sammanfogande av halvledarmaterial och den fotoelektrisk effekt genererar el ur solinstrålning.Avhandlingen studerar dagens solceller, med verkningsgrader uppemot 20 % och deras potential att täcka den mindre del av Stockholms elbehov som idag härstammar från fossila bränslen. Genom att se till en uppskattad befintlig takyta i Stockholms kommun och jämföra den med ytan som baserat på solcellernas potential behövs för att täcka behovet, konstateras att endast en liten del av detta kommer kunna täckas. För att solceller skall vara aktuella inom storskalig elproduktion, krävs att de är ekonomiskt lönsamma och att det i dagens läge är praktiskt genomförbart att montera dem inom stadskärnan.
