Analys av instyrning och rolldynamik
When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.
Prisstrategier : En studie om dynamisk prissättning på Major events
Purpose: The purpose of this Bachelor is to analyze how the organizers of a Major event price their tickets and how these strategies consistent and differs from dynamic pricing. The study also aims to analyze whether there are conditions for dynamic pricing in Major events in the future.Theories: Dynamic pricing - Kimes model, Segmentation, price discrimination, variable ticket pricing.Method: The study used a triangulation where a qualitative interview was combined with quantitative data collection. Primary data was collected through a qualitative approach through an interview with General Secretary Tony Wiréhn and Marketing Director Malin Eldh in the local organization of the IIHF World Championship in Sweden. The quantitative data collection was to collect price information from the games played in the Swedish side of the World Championship organization arrangements.Conclusion: The conclusions that can be drawn are that the organizer of Ice Hockey World Championships today largely applies segmentation and also the second and third degree price discrimination. World Cup organization believes that it has something they call "semi-dynamic pricing", which according to this study involves a variable pricing with dynamic tendencies, then prices on some games adapted based on supply and demand during the sales period.
Bäckmans stenhuggeri AB : Möjligheten att skapa ett nytt segment inom stenbranschen
The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.
Studenters hälsa vid Växjö universitet : ? en studie med KASAM, symtom och krav-kontroll-socialt stöd som utgångspunkt
The aim of this study was to examine the relationship between gender and self reported symptoms (physiological and psychological) and sense of coherence (SOC) and Job Demand-Control-Social support (JDCS). The sample consisted of 360 respondents (nfemale= 261, nmale= 99), in the ages between 19-53 (M=25,57, SD=5,77), all students from Växjö University. A quantitative work method was used in the study; data was collected using questionnaires that consisted of self-reported questions, based on three parts: A modified symptom checklist, SOC 13 and a modified JDCS questionnaire. The result of our study showed that both SOC and JDCS had an effect on self-reported symptoms but there were no interaction between SOC and JDCS. No significant gender differences were found regarding the level of SOC.
Hållbar Ö ? en analys av möjligheterna att försörja ett modellösamhälle i Stilla Havet med solel
The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

Authors: Kim Eriksson and Victoria KarlssonPurpose: The essay aims to describe the relations between control systems and how they related to each other, based on an operationalization of the control systems. Research question: What are the control systems relations to each other? With regards whether control systems co-operative, prevents and/or complement each other.Theoretical framework: The essays theoretical framework is based on Malmi and Browns (2008) description of five different control systems and control mechanisms associated with each control system. Research methodology: The method was based on three different data collection methods. These methods were observations, documentation, and semi-structured interviews.Conclusions: It is concluded that the control systems has comprehensive relations. Control systems have more, than one, relation to each other..
STYRNING I ETT FAMILJEFÖRETAG I FINANSBRANSCHEN: EN FALLSTUDIE AV E. ÖHMAN J: OR FONDKOMMISSION AB
The aim of this thesis is to examine what factors that influences the management control in a family business operating in a sector in which they are under-represented. We have therefore conducted a case study of a family business in the finance sector, E. Öhman J: or Fondkommission AB (Öhman). The first conclusion is that the management control in Öhman is influenced by the environment and the increasing size of the company. We have found, however, that it is to an even larger extent affected by the fact that it is a family business even though the company is operating in a sector in which family businesses are not the norm.
Möjligheter och hinder för aggregerad förbrukningsflexibilitet som en produkt på reglerkraftmarknaden
Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid.One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.
Modellbygge av mekaniksystem och riktmotorer i stridsvagn 122
This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.

KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER
The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.
En kvalitetskontroll - Snustillverkaren Fiedler & Lundgren kvalitetstestas
This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.
