Since the abrupt ending of the Cold Wars the international system of politics has been dominated by the unipolar United States. Leading scholars within structural realism sees this stage as just a temporary condition for various reasons. They also target China as aspirant to embody the role of a balancer against USA and pole in a bi- or multipolar system. Some even argue they are destined for superpower.With the help of realisms definition of power I estimate U.S., China's and India's capabilities and judge their potential superpower. I then go on to connect structural realism and role theory to estimate their different statuses in the system.

In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.

The Swedish government ratified on May 1 2009 an amendment of marital law, resulting in same-sex marriage becoming legalized. With the rights of the Christian Swedish state church to officiate weddings originating from the same law, the church was thereby faced with two options: Either officially include same-sex couples in the Christian concept of holy matrimony and keep the right to officiate weddings; or give up the right to officiate weddings altogether. An official decision to accept the terms was reached on October 22 2009, but not without being preceded by an agitated medial debate.This research attempts to analyze the arguments of the debate in three stages: In the first stage the arguments are categorized according to their respective ideological standpoint. In the second stage these categories are examined from post-modern, social constructivist and socialization theory perspectives. Based on this, the third stage sees the arguments analyzed from a viewpoint based in the Copenhagen school concept of securization.The research concludes that the debate does not only simply feature two sides with differences of opinion; but rather that the arguments of the two opposing sides are founded in a common view of the other side as a fundamental threat to ones conception of a sound society..

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

I got interested in this subject when I came in contact with Västtrafiks new paymentsystem myself during my visits in Gothenburg. I suspected problems with the informationmaterial regarding it and others seemed to share my opinion that the payment system wasdiffcult to understand. When I contacted Västtrafik and asked them about the paymentsystem they confirmed that some understanding diffculties had occurred. With thatconfirmation I decided to make it my project to look in to the matter.Some methods were used to identify the problems. The methods could again confirm thatthere were some problems with the payment system and that the information material wasa vital reason.

I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

?ÄTA-work? (Changes, Supplementary and Retiring works) is more or less common in all construction projects whether it is about houses, roads or railways, in the planning stage, or in the construction stage. For the Swedish Transport Administration, which is the largest purchaser of infrastructure in Sweden, ÄTA-work is a hotter topic than ever.Economists and managers want to draw conclusions on the projects share ÄTA-work, while the project manager is concerned about whether it is possible to draw any conclusions at all as each project is unique in itself and has its own merits. There is a big variation in the amount of ÄTA-work in different geographic districts in the Swedish Transport Administration.This study shows that the Swedish Transport Administration does not have a unanimous approach regarding the management of ?ÄTA-work?.

The aim of the thesis is to analyse and understand resolution, repeatability and reproducibility of the measurement system for package distance. The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.

Detta examensarbete behandlar kommutering av en BLDC-motor, borstlös likspänningsmotor, med hjälp av FPGA, Field Programmable Gate Array. Det jämför och diskuterar också skillnader mellan de intelligenta aktuatorer som används av branchen idag med dumma aktuatorsystem och syftar till att bygga kunskap kring ämnet. Allt högre krav ställs på kommunikationen i ett fordon vad gäller hastighet och datamängd och av denna anledning är det av stort intresse att utreda om ett teknikbyte av ett driftkritiskt system som en BLDC-aktuator är möjligt och lämpligt.Som en fortsättning på tidigare examensarbeten som behandlat reglering av en borstlös likspänningsmotor med hjälp av en dum aktuator löser detta examensarbete ett problem rörande färdigskriven kommuteringskod som uppdagades. Att använda en FPGA för att ta fram kommuteringssignaler till drivsteget ger en försumbar fördröjning av de pulsbreddsmodulerade signalerna som reglerar motorn och därmed uppnås en fungerande dum aktuator som uppfyller Scanias krav för kommutering av BLDC-motorn.Dumma aktuatorer är på många sätt ett bättre alternativ än dagens intelligenta aktuatorer. Fördelar och nackdelar med tre olika system inom områdena uptime, produktionsvolymer, prisnivå och kostnader, reglerprestanda, IO-krav och eektkrav jämförs och diskuteras och på de ?flesta punkter pekar resultaten på att ett teknikbyte till dumma aktuatorer skulle ge vinster på era plan..

The purpose of this thesis is to investigate the relationship between space and consumer interaction at WEEKDAY, a contemporary fashion retail store in Malmö, Sweden. The thesis is based on a qualitative case-study and has a social constructionist approach. In order to understand the interaction taking place between consumer and environment we conducted observations guided by Kenneth Burke?s Pentad.The retail servicescape at WEEKDAY is conceived as a metaphorical stage where drama unfolds, analysing and defining the retail space using Kenneth Burke?s pentad of dramatism. We concentrate on the use of two terms of Burke?s pentad, the scene and the act, almost exclusively as we investigate how the scene stimulates the act.

Introducing a new type of IT-structure means a change that employees within an organization must adapt to. Today, many companies have implemented information technology in the form of Enterprise Resource Planning (ERP) Systems and find themselves in th so-called Second Wave stage where an after work is ongoing with continual improvement that involves changes that employees need to understand and act upon. To learn how to work with these recurrent misadventures is of importance because it is seen as a critical factor in order to take advantage of the ERP system and its benefits. To study this a study was conducted through personal interviews at Apoteksgruppen AB which a few years ago introduced a new ERP system. There the authors saw that employees learned in different ways depending on the position, and that the more responsibility this person had the greater freedom this person had to resolve their problems and therefore learned more effectively.

During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.
