Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Slutfasstyrning av missil med explicit prediktionsreglering

Arbetet har utförts på Saab Bofors Dynamics AB i Linköping och dess syfte är att undersöka möjligheten att applicera teorin för prediktionsreglering, Model Predictive Control (MPC), på guidance systemet i en missil av typen Medium Range Air-to-Air Missiles (MRAAM). Även implementering via Explicit MPC har undersökts. I tidigare studier har det visat sig att den moderna slutfasstyrningsalgoritmen Linear Quadratic Augmented Proportional Navigation (LQAPN), som återkopplar missilens acceleration och rotation, uppvisar en bättre prestanda än de mer klassiska styrlagarna. Det främsta intresset med denna studie är därför att undersöka hur tillvida en styrlag baserad på MPC kan mäata sig med dessa resultat. Fördelen med att använda MPC är framförallt att man kan ta hänsyn till styrsignalbegränsningar på ett direkt och intuitivt sätt.

Studier av koppar i mjölk : en prooxidant med negativa effekter på mjölkkvaliteten

The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.

Utveckling av nytt koncept till processmaskin

Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.

Finns preventiva strategier mot muskelskada i lårets baksida hos fotbollsspelare i allsvenskan? : En enkätstudie

AimThe aim of this study was to investigate if the Swedish elite soccer teams, both males and females, have preventive strategies to reduce the risk of muscular injuries in the posterior thigh.MethodA survey was created and sent by mail to all (n=28) Swedish elite soccer teams in allsvenskan (both males and females) to be answered by the head of physical exercise within each team. A pilot study regarding the survey was performed by two soccer coaches on elite level and was revised afterwards. The survey was conducted between May through July 2013. In total, 18 soccer teams participated in this survey.Results10 soccer teams did not respond to the survey, which resulted in a drop out of 36%. Preventive strategies to reduce the risk of muscular injuries in the posterior thigh existed in 16 of the teams.

Ingen reklam tack! Men gärna Ikea-katalogen : En studie kring vad som händer när marknadsföringen kliver in i sociala forum på Internet

The social network services (SNS) on the Internet are becoming more common, and are starting to have a higher range of users, which is affecting Internet marketing. We (the authors) have a feelingthat a growing online marketing within social networks could interrupt the order of social standards. That is why we in this paper have tried to figure out what position marketing has ? and might have ? within SNS, and what impact it will have on social relations.During qualitative interviews along with both representatives of public relation offices as well as with SNS users, we became aware of the occurring strategies of online marketing, and the usersunderstanding of it. In the information from the interviews, we found some interesting contradictions on which this paper underlies.

Från spel till e-sport : Vilka faktorer påverkar att ett spel utvecklas till en e-sport?

Uppsatsen kommer reflektera kring vad som gör ett spel till en e-sport med fokus på tre huvuddelar inom e-sport idag. Detta baseras på Klines, Peuters och Dyer-Withefords teori om Three Circuits of interactivity; Teknik, Marknadsföring och Kultur. Dessa tre delar utgör e-sport.Alla spel som finns på marknaden idag är tävlingsinriktade och går ut på att lösa problem, men alla spel är inte e-sporter och det finns även spel som försvunnit från scenen. Vi ville undersöka hur detta var möjligt. Vilka faktorer är det som gör att vissa spel bli e-sporter?Vi samlade information under DreamHack Vinter 2011 från flera källor inom e-sport.

Det digitala folkbiblioteket : vision och verklighet

Today, "the digital library" is the common way of describing a managed collection of information, with associated services, stored in digital formats and accessible over a network. Digital libraries have mainly been developed at research libraries, but during the last few years public libraries have started to offer similar services.The aim of this Master's thesis is to study how the Swedish public libraries plan to develop their digital libraries according to their mission statements, and in what way they have implemented them at their web sites. 21 public libraries, the largest in each Swedish county, were investigated.The library mission statements are investigated to find out in what terms the digital libraries are described and to what extent. The library websites are examined with respect to what kind of digital services are offered, to what extent they supplement or replace the physical library, and if there are new digital services not found in the physical library.In most mission statements the digital library is referred to in sweeping terms like "IT activities" and "new media". However, a few of the libraries clearly regard the digital library as an important part of the future operations, speaking of it in well defined and extensive terms.The public library websites are relatively homogeneous when it comes to services supplementing physical library activities, like web access to the library catalogue and links to other library catalogues.

Övergödning i Laholmsbukten  En studie av Laholmsbuktens övergödningssituation

This essay discusses the Laholm?s bay and its eutrofication problems. The question of issue is: Have the efforts to limit the eutrofication in the Laholm?s bay been effective? What is the local actor?s opinion whether the measures have been effective or not? What efforts have been made to prevent the leakage of nutrients from fields and forestland? The Laholm's bay is located in the south part of the Swedish west coast. The problem was noticed in the 1960´s by local fishermen that experienced a lack of catch.

Idrottslärares uppfattning av könsblandad och samkönad undervisning : En jämförande studie av undervisningsformer i idrott och hälsa

Children?s utterances have been studied in different languages; however, only a few studies refer to Swedish. The aim of the present study is to describe utterance types, subordinate clauses and utterance length for a group of three and four year old Swedish children without known functional impairments.The study included 29 children, 17 girls and 12 boys, in a larger city in the south-east of Sweden. The children, all native Swedish speakers, were aged 3;0 to 4;11. Sound recordings were made during a playing session with one of the authors in the children?s day care centers.The utterances were divided into the categories elliptical responses, incomplete and partly unintelligible utterances, imitative utterances and independent utterances.

Word-of-Mouse-Effektens Mörka Sida : - En experimentell studie om hur negativ information i dagens sociala medier påverkar konsumentuppfattningar

The Dark Side of the Word-of-Mouse Effect- An experimental study of how negative information in today?s social media can influence consumer perception As a result of the electronic revolution of information dissemination, social media as a phenomenon has come to play an important part, both in society at large but also when it comes to business and marketing. Nowadays, knowledge and opinions about brands and products are spread by reputation through a wide range of social media platforms, a phenomenon which in the literature is referred to as word-of-mouse or electronic word-of-mouth (eWOM).The purpose of this paper is to investigate how people?s opinions towards a company and its product are affected by negative information in terms of eWOM. Or more precisely, whether or not there is a difference in this effect depending on information content, concerning company values on the one hand and product attributes on the other.This was done in an experimental setting where two groups of respondents were subjected to fictitious information of different types using established social media platforms.
