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.

Abstract   This degree project comprises 30 credits, i.e. 20 weeks of work. The work mainly deals with the energy balance for a multi-family house in Västerås and the requirements for energy conservation in the Swedish building code, BBR. Calculations of the energy balance are supplemented by a number of interviews. Energy conservation in general has become more important in recent years and the subject is in line with increased public awareness. This importance and attention is explained by environmental problems in general and global warming in particular, but also by rising energy prices.

Då IT idag spelar en central roll inom i stort sett varje organisation ökar även kravet på organisationen att förstå verksamheten och dess processer och vilka problem man försöker lösa med hjälp av IT. I denna studie kommer vi försöka identifiera de problem som är kopplade till kravhantering och kommunikation i ett multi-nationellt företag där kravinhämtningsprocessen sker kontinuerligt snarare än projektbaserad. Vi kommer också att försöka föreslå lösningar på de problem vi identifierar. Datainsamlingen har skett via enkäter och intervjuer. Enkäten skickades ut till slutanvändarna av systemen och intervjuerna riktades till fyra nyckelintressenter i kravhanteringsarbetet.

The aim of this Masters thesis is to investigate if the ideas of the realistic tale in Swedish literature for children can be identified by examining four books for children. The four books are all published between the years 1965 to 1975. The methods used to identify the ideas of the realistic tale are the concepts of alienation and antiestablishment. By using the theory of true and false consciousness represented by Diderichsen and the theory of Socialisation by Giddens, two questions are addressed. The questions are if the ideas of the realistic tale develop a true or a false consciousness.

The recent financial crisis has entailed in a fierce debate whether CEOs variable remuneration has caused unsound risk exposure in public companies. Hence it is considered as interesting to elucidate if this connection exists empirically. With grounding in principal-agent theory, and its implicit assumption of risk adverse agents, this study aims to find empirical evidence for a positively correlated relationship between CEOs variable remuneration and company risk exposure. Through a regression analysis of multidimensional data from 102 listed Swedish companies during the period of 2000-2009, we show that the relationship between CEOs variable remuneration and company risk, in contrast to our expectations, is significantly negative. The coherent result is interpreted as the inherent risk in companies seems to explain the usage of variable remuneration for CEO, rather than vice versa.

Migrationsverket är en myndighet som prövar ansökningar från personer som vill söka skydd, ha medborgarskap, studera eller vill jobba i Sverige. Då det på senare tid varit en stor ökning i dessa ansökningar har tiden för vilket ett beslut tar ökat. Varje typ av ansökning (exempelvis medborgarskap) är en process som består av flera steg. Hur beslutet går igenom dessa steg kallas för flöde. Migrationsverket vill därför öka sin flödeseffektivitet.

Sedan år 2005 har det varit obligatoriskt för börsnoterade företag i EU att följa den internationella redovisningsstandarden IFRS 3 vid företagsförvärv. Vid ett företagsförvärv ska förvärvaren allokera kostnaden för förvärvet genom att först värdera de materiella tillgångarna till verkligt värde, sedan de immateriella tillgångarna och till sist allokera det som eventuellt blir över till goodwill. Att identifiera immateriella tillgångar och därmed skilja dem från goodwill anses vara en svår och komplex uppgift. Företagen har kritiserats för att generellt undervärdera immateriella tillgångar och övervärdera goodwill vid företagsförvärv, för att inte lämna tillräcklig information om hur de kommit fram till goodwillbeloppet och för att inte ta uppgiften att identifiera immateriella tillgångar på allvar.Om denna kritik är riktig, vilket mycket talar för, innebär det rimligen att företagsledningarna har ett intresse av att övervärdera goodwill. Detta intresse kan vara helt oegennyttigt, och enbart för företagets bästa, men det kan också vara egennyttigt.

This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.

As a pet owner you are likely to someday face the decision to euthanize your pet and as a veterinarian or veterinary technician you are the one to perform this euthanasia. The reason for euthanasia may be depending on the animal, for instance illness, age and behavioral problems or depending on the needs of the owner or the society, so called convenience euthanasia. Many different euthanasia methods can be used when putting an animal to sleep. The method preferred in animal hospitals is pharmacological euthanasia either by inhalation of anesthetics or by injection of a euthanasia agent. If the pet owner wishes to be present during the procedure it is important to prepare him for what will happen. Many animals are sedated before the euthanasia in order to reduce anxiety and to ensure a softer transition between life and death. The euthanasia agent can then be administrated for instance intravenously or intraperitonealy.

Syftet med denna uppsats är att översätta och lokalisera samt utvärdera en chatt från svenska till engelska. Chatten utgör en social konversationsmodul, med en virtuell agent i ett matematiklärspel. Chatten är implementerad med AIML, som representerar indata- och utdatayttranden med mönster, bestående av ord, fraser eller meningar. Översättningen innebar att översätta dessa mönster i en ordlista. Denna användes sedan för att generera en ny AIML-representation på målspråket, det vill säga engelska.

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

The industrialized timber housing process is capable nowadays to build multi-storeyhouses since fairly new changes in the Swedish regulations where made after theadmission of the European Union in 1994.The industrialized process moves parts of the construction process into a highlyeffective factory where 3D-volumes of the building are prefabricated beforetransportation to the building site for assemble.The assembly process is relatively effective compared to the completion of thebuilding service system and this is therefore the main focus in this thesis. This thesisattends problems with completion of the building service system, and thereforedemarcates from other aspects, such as technical and economic aspects, of thebuilding service system.The degree of completion of the flats differs from completion of the connectivepassages, for example hallways, in a way that suggests a need for further investigation.This thesis includes analysis of the possibilities to increase the prefabricatedconnective passages, to the extent of containing building service systems.An increase of the prefabrication of the building service system has a greatdevelopment potential, even though some restraining factors need to be solvedbefore implementation.This thesis was made in collaboration with two of Sweden?s leading companies on themarket of multi-storey industrialized timber housing, Moelven ByggModul AB andLindbäcks Bygg AB..

Sedan början av 1990-talet har både antalet VD-byten och andelen institutionellt ägande konstant ökat. Tidigare studier visar på att ägarstrukturen i bolag påverkar frekvensen varmed VD:ar byts ut. Däremot har det inte genomförts någon svensk studie avseende sambandet mellan VD-byten och institutionella ägare. Syftet med denna uppsats är att undersöka huruvida institutionella ägare i svenska börsnoterade bolag under tidsperioden 2001 till 2009 påverkar VD-byten. För att besvara syftet har en kvantitativ metod valts.

The EU has decided that it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied:? Certificate system. A certificate system involves two parallel markets, one for trading electrical energy and one for trading certificates of origin.? Separated Markets.

AbstractTitle: Serial recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.
