This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

AIM: To illustrate caregivers? experiences of living with a family member suffering from Chronic Obstructive Pulmonary Disease.

We are in an emerging digital society where we are increasingly dependent on the mastery of IT and digital technologies to better carry out our everyday tasks. They cover everything from keeping in touch with family and friends to pay bills and declare. At the same time there are those who have not learned how to use the new technology and live their lives outside of the digital society. What happens to these people, in a society that is becoming increasingly digitized? Do they take harm by being in digital exclusion? It looks like this are issues that will not become less important as digital technology constantly changes.

This study concerns paratransit service in a relatively small municipality in Sweden. The aim of this study is to describe the user's experience of paratransit service. The question formulation is mainly built around the user's experience of paratransit service and their view on what impact paratransit service has on their lives. The empirical data consists of ten interviews with ten different paratransit service users with ages ranging from 25-95 years. The data has mainly been analyzed through concepts of independence, empowerment and trust. The result of this study shows that paratransit service in many ways can be described as a crucial part of the users' lives.

In Sweden approximately ten percent of all children grows up in a family where at least one parent is having an alcohol related addiction. Since 1998 the development of group activities for children in this situation has been immense. The aim of group activities is to break the child's isolation and make them feel that they are not lonely in their experiences, give them knowledge about addiction and relive the pressure of guilt and responsibility.In a comparative study we examined studied how two different group activity models one with the conception of illness and one without, use the children's network to support the group process. The aim was also to find each models definition of the "normal family", since we understood the groupactivity as a part in the normalization process. We reached our aim through interviews with group leaders and by literature studies.

Datorerna säljs till flertalet olika kunder som monterar dem i allt från skogsmaskiner till tåg. I de olika fordonen varierar spänningen i de befintliga elnäten. Detta skapar behovet av att omvandla spänningen till en nivå som datorerna klarar av.

A Biogas plant in SLU?s (Swedish University of Agricultural Sciences) management sustains to behave in con-nection with the new animal stables at Lövsta. There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others substrates that can arise in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study of different investment scenarios.

The alpaca is a camelid that originate from the South American highland. During recent years it?s been possible to keep alpacas in other parts of the world. Today there is a world-wide interest in alpacas, but there is still limited knowledge about this fascinating animal. There are approximately 350-400 alpacas in Sweden in 2007.

Bakgrund: Patienter som har haft stroke kan uppleva många hinder för välbefinnande. Sjukdomen i sig kan innebära trötthet, depression och olika funktionshinder. Omgivningen kan öka illabefinnandet om den präglas av fördomar, brister i vården och problem i relationer till anhöriga. Coping innebär att hitta bemästringsstrategier som reducerar stress och illabefinnande. Syftet: Att genom självbiografier beskriva hinder och förutsättningar för coping ur ett livsvärldsperspektiv hos människor som haft en stroke.

The purpose of this essay is to discuss and compare different ways of learning new words and expanding your vocabulary in a foreign language. This is done by an examination of relevant literature and available research, as well as by an empirical study with two upper secondary school classes, in which two different methods are put to the test: one traditional method of the kind that is found to be most common in second language acquisition, and one designed to take existing research into account. The results show that, although effective in the initial stages of acquisition, the traditional method, where words are learned in isolation and via translation to L1, results in a very limited form of knowledge. A big part of the words acquired via this method is also forgotten soon afterwards. The other method, where words were learned and tested in its proper context, was found to result in a broader form of vocabulary knowledge, covering more aspects, and that remained over time.

The aim of this study was to investigate if the botanical composition of haylage affects pH, dry matter content and microbial composition of the faeces in horse and pig and ileal environment in pigs. Two separate studies were conducted where pigs and horses were fed two diets containing haylages with different botanical composition. The first haylage was from a tilled land dominated by timothy and meadow fescue and the other haylage came from a meadowland with a large inclusion of dandelion, 25 % and common couch. The dry matter content (70.8 % and 73.0 % respectively) and the pH-value (5.7) were similar in both feeds. The first study was made as a three-periods switch-back study with 7 Standardbred horses. In the first and the third period, 7 and 9 days long respectively, the diet consisted of the haylage from the tilled land, oats, sugar beet pulp, soy bean oil meal, lucerne pellets and brewers yeast.

The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

Various Fusarium species causes some of the most common cereal diseases worldwide. Besides the yield losses that can be a result of these diseases, strains from several Fusarium species can produce mycotoxins, some very toxic. The aim of this study was to investigate which Fusarium species and how many that occurred in winter wheat grains from Mälardalen and Kalmar län, if there was any difference in the distribution of Fusarium fungi between the regions and the potential within species to produce mycotoxins belonging to the group trichothecenes. Winter wheat grains collected in 2009 from ten fields (unsprayed plots) in the two regions were analysed for Fusarium species. PCR was used to amplify the TEF region where after the samples were sequenced.
