Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

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.

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.

Utvecklingen inom digitala medier har gått väldigt fort under de sista åren vilket i sin tur har lett till att användningsområden för digitala medier även har ökat. Ett av dessa användningsområden har varit inom event-industrin där ökandet av digitala medier märks väldigt tydligt.Denna studie ska undersöka om det kan vara så att event-industrin gynnas av digitala medier och kan sammanfattas med en huvudfråga samt en viktig underfråga:? Hur använder event-industrin sig av digitala medier?o Ökar interaktiviteten då digitala medier används?Jag har intervjuat två personer, Magnus Milefors från BSP Marketing och Ulf Lesley från Unify för att ta reda på hur de använder sig av digitala medier i sina events. Med hjälp av min undersökning kring digitala mediers utveckling och användningsområden har jag kommit fram till att det idag finns större möjlighet att göra mer attraktiva events med hjälp av digitala medier. Då det gäller interaktiviteten på events är både Milefors och Lesley överens om att det är en av de viktigaste sakerna att uppnå.

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

Titel: - Gör någonting roligt! Vaddå ska vi kasta pil eller?! En studie kring betydelsefulla variabler vid skapandet av ett eget event.Författare: Ida Södersten och Ida ÖstmanHandledare: Yvonne von FriedrichsProblemformulering: Hur skapar företag ett eget event och vilka variabler är av betydelse?Syfte: Syftet med denna studie är att analysera och öka förståelsen kring de variabler som är betydelsefulla när företag skapar ett eget event.Studiens metod: KvalitativNyckelord: Eventmarknadsföring, eget event, interaktion, kommunikation, upplevelser, varumärket, nyskapande/uniktDagens mediemättade konsumenter söker individualiserade och värdeskapande lösningar och är inte längre lika intresserade av att lyssna på budskap som är massproducerade. Följaktligen har detta resulterat i ett behov hos företag att hitta nya sätt att differentiera sig från andra konkurrerande aktörer på marknaden och därigenom väcka konsumenternas uppmärksamhet och intresse.Eventmarknadsföring är en strategi som har vuxit sig allt starkare de senaste decennierna och används till stor del av organisationer som ett verktyg i deras försök att differentiera sig. Ett event har olika uttrycksformer och kan arrangeras som ett eget event eller ett sponsrat event. Trots att eventmarknadsföring som marknadsföringsstrategi ökat kraftigt i popularitet bland praktiker har forskningen kring tillvägagångssättet inte hållit jämna steg.  De studier som finns inom ämnet har till stor del utförts och fokuserat på sponsrade event och egna event har inte fått lika stort utrymme i den befintliga litteraturen.

Uppsatsen behandlar sponsorrelationens händelseförlopp ifrån eventets perspektiv. Ifrån matchning, via avtalsförhandling till aktivering av sponsorskapet. Hur eventets image, identitet påverkas av sponsorernas varumärke diskuteras.Det empiriska materialet har samlats in via semistrukturerade telefonintervjuer med respondenterna..

AbstractTrendanalys av rapporterade störningar vid de svenskakärnkraftverkenAnalysis of trends in reported safety-related events atSwedish nuclear power plantsSafdar KargarThis degree project was conducted at the Swedish Radiation Safety Authority (SSM)as part of the bachelors program in Nuclear Engineering at Uppsala University duringthe spring of 2011.The Swedish Radiation Safety Authority (SSM) has developed a Windows baseddatabase called ?ASKEN? during later years. In this database more than 12 000 eventreports are stored sorted in three categories, category 1, 2 and 3. The databasecontains events from the start of Oskarshamn 1 in 1972 till present time.All nuclear power plants in Sweden are obliged to report any deficiency in theirbarriers and/or the defense in depth in obedience to SSMFS 2008:1.When a failure is detected or there is reasonable suspicion of a deficiency, the eventreport should be classified as a deficiency of category -1, 2 or 3 [1].The event reports are logged and archived in the register of SSM. The SSM task forceAnalys av Störningar på elproducerande Kärnkraftverk (the ASK-group), evaluates allincoming event reports and categorizes them according to established criteria.The aim of the project is to study and analyze the event reports in the database andidentity interesting observations and trends which should be investigated morethoroughly by deeper analysis to establish any positive or negative trends of reportedevents. .

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

The topic of this thesis interest is the relation between branding as a place making/marketing technology and the process of regionalization. The main proposition advocated is that the officially communicated image of the Øresund Region, as a cohesive place and community, is a space that has been configured with branding and can be described as a territorial simulation. The concept of territorial simulation consists of two conjoined terms: simulation which aim at explaining the idiosyncratic brand image, as a social formation, which does not represent the place it imitates but commoditise it; and territorial which seeks to visualize the process of the unfolding of this image as a territory. The main argument is made in the third chapter, which traces the process of actualization of the brand image as a territory: ?Øresund?.
