In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. The Hawking mass is quasi-local and defined by the spin coefficents of Newman and Penrose, so first we give a discussion about quasi-local quantities and then a short description of the Newman-Penrose formalism..

The aim of this political scientist paper is to describe and analyze the quasi state Iraqi Kurdistan 1992-2006 using the theory of Kolstö about how and why quasi states develops and the theory of Pegg regarding how the international society deal with quasi states. A qualitative case method is used. In the study the two theories are combined. Iraqi Kurdistan is used as a case to study to confirm Kolstö?s and Pegg?s theories.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

The purpose of this study is to study the Swedish Tax information campaigns in 2010-2012. Questions about what worked better than others, and what impact this has had has been set up. The study shows that work has essentially divorced by 2011,worked with a significant amount of local material. This work had an impact on mass media published locally in newspapers. This work fits well with research in the area showing that messages should be tailored to the target audience and capture the target group's interest.

There have been various results in research focused on why people are attracted to religion and religious movements. This is also the case with the reasons why people are attracted to far?right nationalist movements. The focus of this thesis is to analyze British National Party?s political documents after nationalistic quasi-religious elements.If nationalism was to be seen as a form of religion or as a substitute for religion the result could be a better understanding of why people are attracted to nationalist movements in general, and also to far-right movements.

QUASI-projektet är ett tvärvetenskapligt forskningsprojekt som inkluderar universitet och högskolor i fem europeiska länder. QUASI-samarbetet fokuserar på forskning om jästceller. Projektet avslutades i maj 2007 och de vetenskapliga resultaten ska förklaras för allmänheten. Syftet med mitt examensarbete har varit att utforma lättbegripliga texter om QUASI-projektet för att informera allmänheten om projektet och resultaten. Texterna ska publiceras på en webbsida.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

Background: Mass customization has been identified as a competitive business strategy by both companies and academics because of its ability to incorporate the voice of the customer into companies? products and services. Although mass customization may sound appealing, the strategic concept is still developing and firms adopting this business strategy face several challenges. Production concerns are of high relevance since mass customization implies a high level of customer involvement in the product design. Since the areas are closely linked it is reasonable to ask how a mass customization strategy affects production concerns.

The purpose of this essay, ?Now they are chasing paper-less - A qualitative discourse analysis of mass medias depiction of the Reva-project and the work of the police?, is to analyze how mass media portrays the Reva-project and polices work with the project. The basis for the essay will be eight selected newspapers. The Reva-project implies collaboration between the Police, the Swedish Migration board and the Swedish Prison and Probation Service within the border police. The aim of the project is to enhance the efficiency and the execution of the border police work, in accordance with the government?s target.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

This study is about how a swedish brand within the food industry that experiences a crisis following a product failure. It focuses on three areas following the crisis and these are crisis management, recovery strategies and brand management. This study seeks to explain how these areas interact in relation to massive exposure to mass media and how they interact restore the brand's potential loss of reputation. This study was conducted as a case study with a deductive and qualitative approach. The data gathered to this study was mainly based on newspaper articles and complemented with semi-structured interviews with twelve local retailers of the brand..

When a crisis hits a company, it is very important that the company communicate with its customers. Communication is important for a company in crisis because this is a way for the company to tell their side of the story and thereby try to get the customers to see things their way. Because mass media reaches a lot of people, it is a simple and fast way for companies in crisis to get their message out to the world. Mass media can be very useful for a company, but it can also be a problem. Mass media and companies in crisis may or may not have the same purpose with the communication.
