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.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

The Innovation- and Design Engineer program at Karlstad university is a three year long engineer education. In the last phase a final piece is to be done and in this case Boda Borg in Skellefteå is the company in need of product development. Boda Borg is a company in the experience industry and they are located in nine cities from Gällivare in the north of Sweden to Karlskrona in the south. Boda Borg is a franchise company where every facility is their own. As a visitor you will experience physical challenges as well as intellectual in adventure rooms which are serial linked.

Purpose: The purpose of this thesis is to investigate whether abnormal stock returns could be identified as a result of a layoff announcement during weak economy.Method: An event study methodology.Theory: Efficient market hypothesis, signal theory.Empirical results: Quantitative data from observations of stock prices in thirty two companies listed on the Nasdaq OMX Stockholm, in the period 2008 -2012.Conclusion: The results indicate that the market reaction was negative because there were negative abnormal returns on the Stockholm Stock Exchange during the period 2008-2012 in connection with the layoff announcements. The market reaction was milder when staff reductions were carried out as a result of a restructuring and stronger when staff reductions were carried out as part of a cost reduction program.The layoff announcements elicited different market reactions depending on the company's industry affiliation. The most negative reaction was in the Healthcare industry. Negative abnormal returns were lower in industries Industrials, Consumer Services and Consumer Goods. There were no abnormal returns for shares of companies in the industry Financials.

The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.

Dyskalkyli (specifika ra?knesva?righeter) a?r en av flera orsaker till matematiksva?righeter. Studier har pa?visat samband mellan dyskalkyli och dyslexi och att personer med dyskalkyli har sva?rt att klara skolmatematiken. Tva? skilda synsa?tt fo?rklarar orsaken till dyskalkyli: systemteorin och modula?rteorin.

This study was performed in order to evaluate if the method of collecting uterine secretion by the tampon-method is representative for use in studies of uterine secretions in mares. Uterine secretion collected by tampon in six mares was compared with secretion collected by aspiration, regarded to be a native sample, at the Institution of Obstetrics and Gynaecology, SLU, Uppsala. Proteinanalysis was made at the Department of Farmaceutic Bioscience, toxicological unit, Uppsala University. Cytological smears and ultrasonography was used to assess if the tampon had caused an inflammatoric reaction that could influence the protein content of the samples. The results suggest that the tampon and aspirat method do not differ when it comes to proteinconcentration, but the distribution of proteins differ between these different collection methods. This difference could not likely be explained by means of proteins due to an inflammatory reaction from the tampon, since neither the cytological nor the ultrasonographical examination gave any indications of inflammation.

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

The aim of this study is to examine how the public responds to the journalists? use of subjectivity in the reporting of broadcasting news. The investigation is a qualitative study based on nine interviews with respondents in ages of 21 to 25 from different parts of Sweden. After showing five examples of news reporting with a subjective approach, the respondents gave their look on the use of subjectivity. The theoretical frame of the investigation is founded on the theory of framing (de Vreese, 2005; Entman, 1993) and the discussion concerning the terms objectivity and subjectivity (e.g.

AbstractWe have been honored to work with a company called Frimeko AB. Frimeko is located in Halmstad where they make and sell furniture for school and office environment. Our task is to construct a new, more modern sewing machine table for schools. The task is to use the same function as before, ease the storage and production of sewing machine.Efforts to develop the new sewing machine table resulted in that we came up with an innovative design that the company is pleased with.During this project the group has used the method from ?Fredy Olsson Konstruktion? .

An airline company that operates with its fleet needs to ensure that maintenance of a following and certain standard will be implemented. In this project we have sorted and divided the various working procedures of Malmö Aviation into Work Packs. These procedures are mandatory and must therefore be implemented in order to keep the aircraft airworthy at any time. Our task was to optimize and sort these working procedures by zone, panels, access and down time. We have created a maintenance program which Malmö Aviation can use and we have sorted their working procedures in B and C- Checks.Maintenance procedures that did not fit into our Work Packs have been gathered and sent back to Malmö Aviation for further inspection.This project has required a lot of extra reading in manuals and we have had a great insight into the complexity of a technical organization such as Malmö Aviation..

The purpose of my independent work was to develop and test a task-specific assessment matrix to the students writing logs that occurs in connection with their APL (workplace-based learning). The matrix is based on upper secondary school subject plan House building from The Swedish National Agency for Education and the four courses House building process, House building 1, House building 2 and House building 3 - conversion. Due to the matrix structure, I used the example matrix of Malmö University. The task-specific assessment must both serve as a guide for students in the implementation of the log writing, and in the evaluation of the assessment work. Both students and teachers then get a common assessment tool for evaluation.
