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.

For a long time economic tax equalization system in Sweden has been creating dispute between Swedish communities. Despite the main purpose of the system - to reduce disparities and create equal economic opportunities for all communities ? some regions were not satisfied.The main purpose of this study is to determine what extant has equalization tax on investment spending of Danderyd municipality during 2000-2010 year period. The study is based on annual reports and personal interviews. The theoretical frame of the investigation is founded on Fjertorp's classification of investments and public choice theory.The investigation shows that there were no significant changes neither in investment spending or equalization tax during 2000-2010 period, even after the last changes of economic tax equalizations system in 2005.

Urbanisation has increased the distance between the urban and the rural. Urban agriculture can be a solution to overcome that distance. The characteristic of urban agriculture is the intensive production in intra urban and peri-urban areas. Until 1950s food production in cities was an important part of the urban economy and the urban food supply. Since the 1950s the urban located production of food has almost ceased in Sweden, partly as a result of cheap food imports.

The aim ofthis study was to examine how economic growth affects the level of democracy inauthoritarian states. Some of these states have experienced high economicgrowth. However, one can discuss how it affects the country?s democratization-process.For that reason this study was needed to contribute to a clarification of howeconomic growth can affect authoritarian rule and democratization. This wasdone through an examination of the development in China.

ABSTRACT Poverty, and in particular child poverty, is a serious social problem. Statistics show that the number of children living in poverty has increased over the last ten years. Earlier research shows that there are huge gaps in our knowledge of how the actors in civil society handle child poverty. With this study we hope to help fill this gap. The aim of our study is to look at how four different organisations working in the civil society in Uppsala perceive and handle child poverty.

Uppsatsen ger historiska perspektiv och ekonomiska analyser av samband mellan ekonomisk utveckling och ojämlikhet. Den teoretiska utgångspunkten är två artiklar av Oded Galor och Omer Moav som utarbetat formella modeller för analys av ojämlikhetens inverkan på tillväxten, med betoning på humankapitalets ökade betydelse i ekonomins senare utvecklingsstadier. Den empiriska undersökningen som författarna gör i artikeln ?Das Human- Kapital: A Theory of the Demise of the Class Structure? för England, är mallen för uppsatsen. Resultaten av den empiriska studien för Sverige ligger i linje med Galor och Moavs slutsatser för England men ett särskilt svenskt utvecklingsmönster spåras..

Variations in fertility have caused a problematic situation in Sweden among other European countries. According to the Council of Europe we are facing an economic and demographic challenge, when the baby boomers of the 1940?s are retiring. Economists have for a long time studied the connection between economic factors and fertility, and several studies have found a correlation between business cycles and birth rates. This connection is again of current interest 2008, when a financial bubble bursts at the same time as a baby boom occurs.

Syftet med studien är att undersöka om det kan skapas fler arbetstillfällen inom forskning och utveckling på den nationella arbetsmarknaden när hela eller delar utav den inhemska produktionen flyttar utomlands. För att undersöka varför företag flyttar sin produktion utomlands har jag tagit mig till hjälp av fem fallföretag. Vidare har jag undersökt vilka länder företagen väljer att flytta till samt de faktorer som påverkar beslutet. Avslutningsvis har jag genom en modifierad version av Romers modell undersökt om fler arbetstillfällen inom forskning och utveckling kan skapas när produktionen flyttar utomlands..

Denna uppsats studerar huruvida internationell diversifiering medför några vinster gentemot att följa en inhemsk strategi. Genom analys av dels sverigefonder och dels globalfonder slås det fast att så är fallet. En internationell strategi medför en lägre risk än en sverigekoncentrerad. Uppsatsen undersöker också fenomenet Home Bias, d.v.s. den snedvridning som innebär att en allt för stor andel av kapitalet placeras i hemlandet.

The aim of this paper is to analyze aid, grouped into sectors, and its effect on growth in developing countries, to find out which type of aid has had the most positive effect on growth. We compiled a regression analysis based on panel data over 81 developing countries from 1975-1999. In our first regression we considered and group countries by institutional quality, in the other we considered and group countries after regional differences. As a measure on institutional quality we used the KKZ-index. The principal aim of this paper was to find out what kind of aid is the most efficient in its influence on growth in LDC?s.

Background: Resources that are hard to put a value on and cannot be classified as assets in the balance sheet as well as the development towards the information society has led to an increasing need and use for voluntary information in the annual reports. The increase of voluntary information can foremost be seen in the field of human resources.Purpose: The purpose of this thesis is to describe the development of voluntary information about human resources in the annual report of a number of Swedish quoted companies. The purpose is also to see if there is a difference in the development between manufacturing companies and service companies.Method: Six manufacturing companies and six service companies were chosen from the Stockholm exchange A-list. Using both a qualitative and quantitative research method the annual reports of the chosencompanies were studied for the years 1995, 1997, 1999, 2001, and 2003. A model consisting of seven categories; health, diversity, recruitment, staff turnover and comfort, benefits and motivation, education and competence development, was developed to clarify were the development took place.Conclusions: After finishing the study one can tell that the amount of voluntary information about human resources in the annual report has increased even though the percentage share of the total annual report only has increased appreciably for manufacturing companies.

The Vaxholm conflict was initiated when the Swedish Trade Union for Construction Workers shut down a construction site in order to prevent a Latvian construction company to build a school after the two parties had failed to agree upon a collective agreement in compliance with Swedish regulations. An emotional public debate followed that resulted in a discussion of the proposal for the Services Directive of the EU, based upon the country-of-origin principle. In this thesis we will analyze whether the country-of-origin principle or the country-of-destination principle is best suited to capture the gains-of-trade that the common market hoards and improve welfare within the EU. We conclude that the country-of-origin principle is the more apt of the two, though it leads to some short-run costs such as structural unemployment. But these will be more than outweighed by the gains in aggregate welfare for the EU in the long run..

Denna uppsats behandlar det kommunala utjämningssystemet. Dagens system består av en inkomstutjämningsdel, kostnadsutjämningsdel, ett strukturbidrag och en regleringspost, som antingen kan bli bidrag eller avgift beroende på hur mycket pengar staten anslår till systemet. Till detta har använts teorin om konkurrensproblemet, olika teorier om vad kommunerna bör göra, varför kommunerna bör finnas och hur de skall finansiera verksamheten. Två kommuner har valts ut, Vellinge och Trelleborg, för att i två fallstudier studera effekten av systemet för den enskilda kommunen. Slutsatsen är att i dagsläget behövs utjämningssystemet för annars träder konkurrensproblemet till.

Uppsatsen analyserar nyintroduktionerna på Stockholmsbörsen mellan 1992 och 1995 och deras prissättning och värdeutveckling på 10 års sikt i syfte att undersöka hur kapitalmarknaden historiskt sett har lyckats med att marknadsprissätta företag som har sökt sig till börsen. Central för analysen är hypotesen om informationseffektivitet vid prissättningen av nyintroduktioner och den därav följande värdeutvecklingen. Resultaten påvisar inga systematiska avvikelser ifrån de förväntade avkastningarna enligt CAPM. Informationen om nyintroduktion i kombination med egenskapar som MV, P/B, betavärden, börsklimat under introduktionsåret eller branschtillhörighet räcker inte för att framgångsrikt tillämpa aktiva handelsstrategier som realiserar signifikanta överavkastningar under något av de 10 åren som följer på nyintroduktionen eller över hela livslängden upp till 10 år..
