The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.

I denna studie undersöks två algoritmer för att rendera volumetrisk data. Studien syftar till att undersöka om det är möjligt att använda dessa algoritmer i en datorspelsmiljö. De båda algoritmerna, som kallas för shear-warp-algoritmen och footprint-algoritmen, jämförs mot varandra för att ta reda på vilken som är bäst på att lösa uppgiften. Algoritmerna testas också för att se om de är lämpade att verka i en datorspelsmiljö med avseende på om de kan generera tillräckligt antal bilder per sekund.Resultatet av studien visar på att ingen av de två algoritmerna är lämpade inom den domän de är tänkta att verka inom. Även om shear-warp-algoritmen är effektivare på att lösa sin uppgift än vad footprint-algoritmen är så visar studien att ingen av dessa två algoritmer är lämpade i den domän de är undersökta i..

I den här uppsatsen beskrivs en ansats till att med hjälp av statistiska metoder förutse utfallet i förmögenhetsra?ttsliga dispositiva tvistemål. Logistiska- och multilogistiska regressionsmodeller skattades på data för 13299 tvistemål från 5 tingsrätter och användes  till att förutse utfallet för 1522 tvistemål från 3 andra tingsrätter.  Modellerna presterade bättre än slumpen vilket ger stöd för slutsatsen att man kan använda statistiska metoder för att förutse utfallet i denna typ av tvistemål..

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Denna rapport beskriver VisMT 2. VisMT 2 är en programvara som utvecklats som ett examensarbete av Daniel Peterson vid Linköpings Universitet i samarbete med organisationen NVIS (Norrköpings Visualiserings och Interaktionsstudio).Målsättningen för VisMT 2 var att skapa en enkel och kraftfull mjukvara som på ett innovativt sätt synliggör resultat och prestanda för butiker i detaljhandelskedjor. Vidare sattes målet att programmet skulle grunda sig i ett explorativt gränssnitt där användaren kan undersöka butiksrelaterade data i både spatial och temporalplanet.Programmet gavs ett gränssnitt med sammanlänkade vyer. Interaktion i en vy ger återkopplingar för relaterade data i en annan vy i realtid.Programmet utvecklades i C# .NET och använder Managed DirectX för att generera 3D-grafik. Det slutgiltiga resultatet uppfyller väl den målsättning som skapades vid projektets inledning.

The snow leopard (Panthera uncia) is an elusive felid, native to the mountains in central Asia. Basic knowledge about the snow leopards? ecology has long been lacking but is advancing with the help of the GPS-technology. GPS cluster analysis can provide insight in the diet and prey selection of elusive predators, such as the snow leopard. Acceleration data from GPS collars can be used to study animal behavior but the two have never been combined to gain more detailed information of the feeding behavior of large carnivores.

We have through our theoretical framework been able to create a simplified measuring tool for a KIZ; the S-TKL. We have found that the S-TKL is possible to implement on the Öresund Region but with some flaws. Even though the Öresund Region has implemented the mindset of a KIZ, accurate statistics are in some areas hard to find. We can also through our empirical findings say that it is difficult to use the S-TKL on Shenzhen. The data we have found gives a good indication of both of the regions.

Internet's entry into our home has changed our communication capabilities. As a result more and more services in the digital world are available. Besides e.g. shopping, gaming and general information, different social networks now offer preventive and therapeutic health-oriented services. When being asked by several young people, with whom I have been working in a clinical setting, to offer conversations over the Internet that enables both to see and to hear each other in real time, I decided to conduct a pilot study which is presented in this paper. The aim was to investigate the feasibility of offering supportive therapy using video calls over the Internet.

Companies will increasingly begin to link their applications, and the technology that makesthis possible is called integration. The more applications that are connected, the more of the company's data flows through these integrations. It is also clear that data analyses to create business value and to get competitive advantages against its competitors are important. In this paper, we examine how companies create business value and competitive advantages throughthe integration platforms and metadata from the integrations. We have interviewedpeople from three companies in the industrial sector, each with an integration platform.We have also interviewed Enfo Zystems, a company that provides development andmanagement of integration platforms to these customers.

Domännamnssystemet DNS är en vital och ofrånkomlig del av internet. Det är dock sårbart för attacker. DNSSEC är ett sätt att minska sårbarheten hos DNS. I detta examensarbete har data om ett antal domäner samlats in med hjälp av Zonemaster och domain information groper för att sedan bearbetas med hjälp av bash-skript och java-kod. Detta data har sedan analyserats.

Internal communication is an important factor in organisations today. For many system development teams it?s critical that the communication works well. Without communication, success would be impossible. This study aims to highlight the effect communication has on the members of agile project teams.

Aim The aim of the thesis is to explain the factors that affect the auditor's recommendation concerning audit services to customers who are not subject to mandatory auditing.Background and problem In 2010 mandatory auditing for small companies was abolished. It is common for the auditor to provide recommendations re-garding whether or not a customer should chose to retain the audit. The question is which factors can explain the auditor's recommendation.Method and empirics This thesis uses a deductive approach with inductive elements and a combination of qualitative and quantitative data is used. The qualitative data consists of a pilot study and the quantitative data consists of a questionnaire survey. The analysis of the empirical data was performed using regression analysis.Theory This thesis applies an eclectic approach where the starting point is legitimacy, institutional theory, professional theory and decision making theory to develop a model.Results and conclusions The notion of the recommendation as well as the extent of the recommendations can be explained by factors related to the auditor's agency affiliation and the auditor's personal qualities..

Våta kopplingar används i automatiska transmissioner för att överföra vridmoment. De primära komponenterna i en våt koppling är de oljesmorda pappersbaserade friktionslamellerna och separationslamellerna gjorda av stål. Volvo Construction Equipment (Volvo CE) utvecklar och bygger automatiska powershifttransmissioner med våta kopplingar till sina anläggningsmaskiner. Volvo CE och Luleå Tekniska Universitet (LTU) bedriver tillsammans forskning om våta kopplingar som involverar pappersbaserade friktionsmaterial. De två vanligast förekommande materialen i produktion, i detta examensarbete benämnda som material A och B, testades i en testrigg på LTU.

The aim of this study was to investigate if a mechanical recruitment process could be a useful tool for employers to avoid discrimination. National and international law protect jobseekers from discrimination during the recruiting process. Despite this individuals frequently report that they are treated unfairly when they apply for a job. In line with this research shows that some individuals do not have the same opportunities in the labour market as the rest of the population. This study focus on discrimination based on ethnicity, age, gender or disability.Today most of the hiring decisions are based on employers professional judgement.
