En analys av nuvarande och framtida trygghetsarbete i fastighetsbolag "trygghet och säkerhet en investering för framtiden"
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Simulering av simulinkmodeller med Extended Kalman Filter
Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.
Hur marknaden bedömer europeiska företagstillkännagivanden vid etablering i BRIC länder
The aim of this study is to examine how European companies? stock price is affected by an announcement about foreign direct investment in one of the BRIC countries. Another aim for the study is to examine if the market reacts differently to the three modes of entry methods in a given BRIC country and to examine if the market reacts differently to different European countries. The study also set out to answer if there were any effects of the three modes of entry that was visible a short time after the announcement. To answer and examine this, the authors used the event study approach. The study was conducted with a sample of 47 companies from France, Norway, Spain, Sweden and Germany.

Historiesyn - Drivkraften i försoning : Ett kvalitativt arbete av Commision on Amnestys historiesyn
Title: Festivalernas Intåg ? Korröfestivalen- en bordunstämmas resa genom festivaliseringenThe Korrö festival- The establishment of a Swedish Folk Music Festival.This thesis describes how folk music festivals have been escalating during the past few and how they have influenced Swedish folk music. To reach my results I have been studying one festival in particular which is the Korrö Folk Music Festival. This event started in the mid-eighties as a small happening that attracted almost exclusively musicians that were a part of the bordooon movement. The bordoon movement gathered a couple of days in the summer at what they called the ?Korrö bordunstämma? to build instruments and play folk music.
Resultatutjäming : en jämförelsestudie efter införandet av IFRS
Syftet med denna uppsats är att öka förståelsen för användning och tillämpning av Event Marketing. Varför företag använder sig av det samt vad eventbyråer tror är företagens motiv. Event Marketing innebär helt enkel att marknadsföra en produkt eller en tjänst genom ett evenemang. Eventet samlar en viss målgrupp i både tid och rum men är på så sätt även begränsad i antalet kontakter som den skapar.Metoden som har använts för denna uppsats är av kvalitativ karaktär. Under arbetets gång har vi genomfört fyra intervjuer som flerfallsstudier.
Mediernas konstruktion av en politisk händelse En kritisk diskursanalys av två svenska morgontidningars medierapportering av oroligheterna till följd av presidentvalet i Kenya
News value is an essential part of which event media chooses to report about. Political events consider to bee news with potentional large value. Media has an enormous power and possibility to create news and construct there own reality and where the readers is given a false expression of what really happened. Today the media must show profit and that indirect affects how the media choose to describe political events. In the Kenya case is it therefore possible to draw the conclusion that the two news paper has different construction of the political event in Kenya.
En fordonsförares upplevelse av accelerationer som grund för en effektiv simuleringsmodell
Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.
Tro det om du vill, men relevant är det - Hur företag inom handel använder Event Marketing
Företag inom handel är underrepresenterade i litteratur kring Event Marketing. Kommunikationsverktyget som erbjuder interaktion tilltalar dagens upplevelsesökande konsumenter. Event Marketing som verktyg är i sin tur underrepresenterat inom Brand Management. På grund av Event Marketings aktualitet i dagens samhälle borde det teoretiska gapet studeras. Uppsatsens syfte var således att undersöka hur företag inom handel använder Event Marketing för att framhålla och stärka sitt varumärke, detta med hjälp av följande frågeställningar: Hur motiverar företag inom handel användande av EM? Hur arbetar företag inom handel med att säkerställa att EM får en positiv inverkan på varumärket? Vilka särdrag kan identifieras, inom användandet av EM, för företag inom handel? Undersökningen genomfördes med ett arbetssätt liknande det abduktiva genom öppna kvalitativa intervjuer med tre företag inom handel samt tre eventbyråer.

Simulation driven design : An iterative approach for mechanical engineerswith focus on modal analysis
This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.
Eventkommunikation : En kvalitativ undersökning om hur event används för att kommunicera ett budskap
Den här uppsatsen är en kvalitativ analys om hur Stockholm stad har valt att använda sig utav eventkommunikation för att kommunicera ett budskap. Eftersom att event kan användas som strategi inom flera typer utav kommunikationsområden, används här begrepp som kan relatera till flera av dessa områden.För att komma i närmare kontakt med eventet har intervjuer genomförts med projektledaren och kommunikationsansvarig för Kulturnatt Stockholm. Genom textanalys, retorisk analys och innehållsanalys studeras intervjusvaren och en reklamaffisch som utformats för att marknadsföra eventet.Det kan konstateras att det utformade syftet för eventet går hand i hand med det kommunicerande budskapet och att Stockholms stads intressen kan återspeglas i reklamaffischen. .

Studentrekrytering : det bortglömda kapitlet inom eventkommunikation
Student recruitment is a subject that seems to be forgotten in the theory of event communication. Yet the area has some specific reoccurring features. Our purpose was to examine these specific features and how to work with these in the best way, and also see how to get the most out of the event communication to the young at event and fairs. Special features we have looked at are the student ambassadors ands their impact, the meaning of a give-away and also if there are any essential factors to get in contact with the young at fairs and events, and if new technology had an important role to play in the area.Our research has been inductive, and therefore, we have created our own theory and reflected it to the larger topic of event communication and its theories. Our research method has been triangular, both quantitative and qualitative; interviews with those who work with student recruitment, and surveys to young people in upper secondary school.Our study showed the importance of student ambassadors and their specific task to be nice, friendly and outgoing.
Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8
The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.
