On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.
E-förvaltningens roll i främjandet av demokrati. En fallstudie om offentlig förvaltnings relation till demokrati med stöd av IT
Information technology (IT) with its enormous capacity involves more and more in our daily activities and public sector is using IT to make their activities more efficient. The government goal with electronic government (e-government) among other things is increasing the availability and service to the public as well as improving the democratic process. Democracy can be strengthened by involving citizens in public decision making process but this goal has not been achieved yet and the development of e-government has mostly been focused on improving efficiency within administration and electronic services (e-services). Promoting the democratic process has been postponed in the development of e-government because of the lack of political commitment and decision. Digital divide is also preventing public sector to promote democracy with the support of IT.
Made by China : Outsourcing av Konstruktionsarbete till Kina
Outsourcing means to contract out work previously done within the cooperation to a supplier.This is an increasing trend today. Traditionally companies have outsourced manufacturing butwith the growing specialization they tend to outsource other activities as well.China?s economical reforms and entrance into the World Trade Organization, WTO, hasenabled international business connections. Since China offers one of the cheapest labours inthe world, many companies have an interest in starting up an activity in the country. Themany foreign investments in China have lead to an economical growth which in turn hasmade it possible for China to invest in the Chinese competence and innovative capacity.The commissioner of this master thesis, SMS, is one of the leading actors in retrieval ofamong other things mounts and stands for flat screens and projectors.
Hur ser skolkuratorer och skolsköterskor på självskadebeteende hos högstadieelever? : En kvalitativ studie om bemötande och förståelseutifrån riktlinjer och policys
This study deals with sustainability reporting in three governmental and three non-governmental Swedish companies in different industries. With increasing demands from the society regarding company?s CSR - Corporate social responsibility, the perspective of accounting gets broader and covers even non-financial information to meet not only the owners? demands but also others stakeholders' requirements. Sustainability has become an important tool for creating company?s business value and a positive sustainable external image.
Examen igen?
This paper will discuss the proposed reintroducing of a final degree in upper secondary school. In a public government inquiry that was released in March 2008 a proposal about reintroducing a final degree in upper secondary school was presented. A final degree has not been a part of the upper secondary school science 1968. Why was the system with a final degree abounded and why do the government want to reintroduce it?Research in pedagogy has through the years presented numbers of theories about assessment.

Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

Digitala kläder? : En studie om traditionella klädföretags it-strategier
This paper focuses on traditional clothing enterprise IT strategies. The purpose was to investigate the correlation between traditional clothing companies IT strategies and their brand. In a market where the competition is high it has become more important that the company targets a customer segment. To reach their targeted customers the company builds their brand with different corporate strategies. This segmentation is necessary because of the high exposure to competition, and a well-established brand could be a prerequisite for profitability. In today?s market, IT has a major impact on the clothing business.

Empowerment : En studie om empowerments påverkan på frontpersonalen i tjänsteföretag.
This thesis is about how the front-staff in two service companies experience empowerment. Competition for business in today's society is becoming increasingly fierce, which means that they must find a way to differentiate themselves from competitors. Service has become a way to compete. Front-staff competence and ability to offer a good service is a crucial factor when the company's success is being measured.Empowerment in business is used as a tool to create motivation and satisfaction of individuals at work. Companies using empowerment can create the freedom and opportunities for employees to act at their own intelligence and discretion.
Europeiska mötesdestinationer : En jämförelsestudie om professionella möten & mötesindustrin i Stockholm, Warszawa & Rom
The meeting industry is a growing industry around the world, and the technological development in recent decades is one of the contributing factors to the increased travel opportunities and meeting industry's expansion. It can be assumed that the technology could replace some of the personal meetings, but humans have always had a need to meet in physical locations in work related purposes, therefore there is no evidence that personal meetings will disappear. Technological development should be seen as complementary rather than a substitute to the existing professional meetings. Public and private sectors within countries has drawn attention to meeting industry's potential, as favored destinations in terms of economic administration, image creation, expansion and acquisition of further market share in the global market. Meeting industry is complex precisely because there are so many different actors and stakeholders that integrate.
