This work has been carried out together with Kapsch TrafficCom AB in Jönköping.The objective of this project is to:Evaluate and investigate the effects given to pictures by HDR and tone mapping.Evaluate if the technology may lead to improvements in Kapsch?s systems.To construct a program which is able to handle some form of tone mapping or HDR-algorithm.These questions will be answered in this report:What kind of effects has HDR and tone mapping-algorithms on pictures?Can the HDR-technology give better data in Kapsch?s systems?The research method used in this report is called action research. This means the authors has investigated the technology by reading different documentations and by testing different algorithms to see what kind of result they give. The report describes some of the tests made to see if the technology is appropriate in Kapsch?s system.There is two smaller reports made by the authors which documenting some of the work.The first report describes the work with different settings for a camera to create pictures with HDR-quality.
Koldioxidsutsläppsbesparing vid biogasproduktion
Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.
Design av PID-regulator baserad på kommersiell processormodul
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.
Wild boar paradise : What makes the Swedish wild boar reproduce more or less successfully?
Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county
to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this
variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.
Barn som behöver MIG : (Mobil intensivvårdsgrupp)
Införandet av en mobil intensivvårdsgrupp (MIG) har visat sig ha goda resultat utomlands med minskade andningsstopp och mortalitet inom pediatrisk vård. Vid Astrid Lindgrens Barnsjukhus i Solna, Sverige (ALB) finns långt framskridna planer på att starta en MIG-verksamhet. Syftet med denna studie var att beskriva pediatriska patienter som faller in under potentiella MIG-kriterier innan inläggning på barnintensivvårdsavdelningen/barnintermediäravdelningen (BIVA/BIMA) på ALB. Studien gjordes retrospektivt genom journalgranskning av inskrivna pediatriska patienter på BIVA/BIMA under 2009. Totalt inkluderades 148 pediatriska patienter i åldern 0-18 år i studien.
Är ökad pressfrihet dåliga nyheter för korruption? - En kvantitativ dataanalys som testar styrkan i sambandet mellan pressfrihet och korruption.
This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.
Visualisering av svarstider mellan mobila klienter och datacenter
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.
Vätskebehandling inom brännskadevård
SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.
Demokrati : En studie om demokratiindex och dess eventuella begränsningar
This essay is about democracy and how a democracy index can be used as a tool to illustratethe gap between reality and ideal. The purpose of this study can be expressed by two researchquestions: Does the Economist Intelligence Unit's (EIU) democracy index illustrate thedistance between reality and the ideal of democracy presented by Dahl? and Can the EIU'sdemocracy index be modified by a) internal adjustments and b) using the variables includedin World Economic Forum?s (WEF) equality index?By using a combination of theories (Dahl?s theory of democracy, Rawls theory of justice andchosen theories critical to liberal democracy) as an analytical framework the following twoquestions have been answered:1) Which of the variables included in the EIU's democracy index have the potential to capturethe level of political equality?2) Which of the variables included in the WEF?s equality index have the potential to capturethe degree of political equality?By using a quantitative method the study?s third and last question has been answered:3) How strong is the rank correlation between the EIU?s democracy index and the WEF?sequality index, that is; how strong is the rank correlation coefficient (rho)?The data presented by the WEF?s equality index indicate that women are systematicallydiscriminated against as a group. From a democratic perspective the EIU may need tomeasure inequalities at a group level in order to capture the lack of political equality betweenindividuals. By reformulating some of the EIU?s variables, by revising the EIU?s point systemand by using the variables included in the WEF's equality index to extend EIU?s democracyindex, the chances of capturing the gap between reality and the ideal of democracy presentedby Dahl would likely increase..

How do teachers in the language unit prepare, plan and implement their reading and writing instruction to Autism pupils? 3.
Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling
The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.
Utveckling av vippgunga för barn i åldrarna 1-3 år
Under våren år 2013 har Emilia Andersson, en designingenjörsstudent på Högskolan i Skövde, utfört ett produktutvecklingsprojekt i samarbete med HAGS Aneby AB. Syftet med projektet var att utveckla en vippgunga vars storlek skulle vara anpassad för barn i åldrarna 1-3 år. Målet var att vippgungan ska kunna säljas över hela världen samt uppfylla den amerikanska standarden och europastandarden för lekredskap.Projektet inleddes med en förstudie och teori-fas, där bland annat litteraturstudie och konkurrentanalys genomfördes och annan information samlades in för att få djupare kunskaper inom ämnet. Därefter började idéer och koncept genereras, som sedan genomgick utvärderingar, så som användartester, vilket ledde till ett slutkoncept. Konceptet utvärderades med hjälp av bland annat hållfasthetsberäkningar och en antropometrisk analys.Den slutgiltiga vippgungan kan trots anpassningen för åldersgruppen, inte bara användas av 1-3-åringar utan också av äldre barn, tack vare att konstruktion och framförallt handtag ger extra lekvärden.
Kunskapso?verfo?ring inom franchisena?tverk : En studie av utveckling och o?verfo?ring av kunskap inom franchisena?tverk
This case study has been conducted within the Swedish fitness chain World Class to explore the opportunities for knowledge development and transfers within franchise networks. We have interviewed the product manager at the World Class headquarter, the owner of a franchise club and a local product manager from the same facility. Our finding indicates that various forms of knowledge transfer occur within the World Class network, particularly in product development and sales. The transfer occurs within the framework set by World Class with regularly scheduled meetings. In addition informal networks provide other means of knowledge exchange between some units.
Styrtransmission för bandfordon
The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.
