The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.

Ever since Lipsky wrote about street-level bureaucrats in 1980 the main belief has been that certain characteristics of their jobs make it exceptionally difficult to severely reduce their discretion. However, discretion comes at a price and if public servants abuse their power the legitimacy of government is at risk and ultimately even the democracy.This thesis address this question by analysing the Swedish employment service which in the beginning of 2001 started a project called ?Af Sverige? trying to improve internal rule of law. By comparing two local and fairly equal jobcentres and how the street-level bureaucrats within use their discretion, I seek to find support for my hypotheses that organizing local jobcentres according to the principles of machine bureaucracy plays a significant part in reducing discretion.My findings show that a jobcentre characterised by strict rules, few units, good communications and a forthright manager who delegates formal power to the employees results in a stricter and more uniform application of regulations among the street-level bureaucrats. My conclusion is therefore unambiguous.

This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.

Elektronikföretaget Mobiltech AB i Karlskrona, Blekinge, var i behov av en ny webbapplikation och visade sitt intresse i att låta oss utveckla en ny mer dynamisk lösning åt dem. Deras mål med systemet var att de själv enkelt via ett webbadministrations gränssnitt skulle kunna redigera alla information på deras företags webbsida. Systemet som helhet omfattas av kategorier, informationssektioner samt en erbjudande panel. Som via en lösning av kod struktur och design, som vi från grunden byggt upp för att passa de behov som finns, bildar en administrerbar sida. Vi utvecklade projektet genom att använda oss av PHP5 och MySQL5.

Rapporten är en sammanställning av gruppens samlade erfarenheter och lärdomar av ett projekt vars syfte var att utveckla ett verktyg som ska visualisera svarstider mellan mobila klienter och datacenter. Genom att använda kontinuerlig prototypning har gruppen kunnat arbeta på ett användarna sätt för att uppfylla kundens verkliga behov. För att uppnå detta användes utvecklingsmetodiken Kanban. Under projektets gång anpassades metodiken för att bättra passa in i arbetet.Projektets användartester har lett till sammanfattande erfarenheter om visualisering av data. Visualiseringar som projektgruppen ansetts tydliga uppfattades inte alltid på samma sätt av användarna.

The Anglo-Saxon trust is not a new phenomenon, but existed as early as in the Middle Ages. The concept is customary among common-law countries, such as England the US,but unfamiliar to civil-law countries like Sweden. The person who creates the trust is called a settlor, the one who holds and administer the property is a trustee and the person who benefits from the settlement is called a beneficiary.In Sweden there is no legislation of how the trust ought to be assessed, but the need to understand it has probably increased with the internationalization.The Swedish Supreme Administrative Court has had a few opportunities to elucidate some of the uncertainties regarding trusts, but chose to abstain. With this The Swedish Tax Panel has very limited guidance from the court when they receive an application of an advance notice.A trust is not a legal entity nor a tax subject. This differs the trust from a foundation and they can not be placed on an equality from a Swedish tax perspective.In an advance notice, 2010-03-23 (dnr 103-09/D) om Inkomstskatt: Inkomst av tjänst ? värdepappersförmån, the Swedish Tax Panel equalizes the trust property with shares when determining how to tax the assets.

The purpose of this thesis is to study how Malaysia Airlines communicated during the two largest crises of 2014. Key questions to be answered are: Did organizational hypocrisy occur? If yes, in what way? Which communication strategies were used? Did the company mediate an unequivocal message and how was the information framed? Did any aggravating factors, which worsened the organization?s reputation, appear? How did Malaysia Airlines manage possible rumours? Was the word contact used as a keyword? The method of choice is a quantitative content analysis and the material consists of 20 different analysis units. These analysis units were collected from social media and Malaysia Airlines website. The quantitative content analysis is based on the theory Situational Crisis Communication Theory, taken from PR, Strategy and Application, Managing Influence, by W.

The aim of this study has been to investigate how the death of a close relative is described in pictures and texts through the eyes of a child character in three picture books. The analysis has also considered how the child character copes with the tragedy and how he or she finds support in the grief process. The books analysed here are Resan till Ugri-La-Brek (1987), Farväl, Rune (1986), and Jättebra Olga! (2010). Since these are works of fiction, this study does not assume that they are an accurate reflection of reality, but the way the child characters act and cope with their grief has been compared with the findings of empirical research on how children react in real situations.The material has been examined by means of a qualitative literary analysis comparing the books according to the research questions. The study finds that the child characters receive evasive explanations from people around them concerning what death means, for instance that the person is sleeping.
