In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a Power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

Our understanding is that responsibility is shifting from the community towards the individual within the field of social work. This resulted in our essay, which aims to study how the representatives within social service assistance and churches in Helsingborg work with personal power. Our aim is also to illustrate how these representatives view the boundaries of responsibility between the individual and the community. Our questions are: How do the representatives work with personal power from a micro and macro perspective? How do the representatives look upon their position as representatives? What do the representatives consider as responsibility of the individual respective the community? And; Are there preventing factors from individual responsibility? We obtained our empirical material from a qualitative method consisting of interviews.

The ISO 9000-series is a set of quality standards created by the International Organization for Standardization. The series is intended to provide guidance to companies in the process of deploying an effective quality management system. The series includes the requirements standard ISO 9001. This standard contains requirements on how a quality management system should be designed and how companies generally must work with quality issues. When a quality management system is introduced, if wanted, a quality certification can be implemented.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

 Detta är endast en del av ett stort arbete, på grund av omständigheterna (till exempel möjligheten att publicera en power point) har vi varit tvungna att begränsa vår publikation till lärarhandledningen. Det finns också en elevutgåva, power point-presentation samt ett prov som inte publiceras. För att ta del av dessa krävs möjlighet att komma åt Biologi C för lärares kurswebb Vt-2008 på Södertörns högskolas intranät. .

New method for measuring road quality- A statisticalstudy of the relationship between road quality andsocioeconomic development A new tool with implications for road maintenance has the potential to yield statistical data for road quality in a large number of regions. This thesis investigates the possibility to develop a method, from this data, for evaluating the effects of road quality on socioeconomic development.The thesis is essentially divided into two parts. Part one looks to qualitatively establish the link between socioeconomic development and road quality and the second part focuses on how to develop a method for evaluating the effects of road quality on socioeconomic development. A method was devised using categorical data and a multinomial regression model. This method provides a comprehensive overview of the complex relationship between a variety of different variables.

In this essay I try to find out how the local political climate in the Swedish Municipal Örebro looks like through the eyes of Michel Foucault. I?ve been focusing on the concept power, knowledge and politic. I?ve been applying the discourse theory on the study and the founder of that theory is Chantal Mouffe and Ernesto Laclau, the discoursetheory is a refinement of Foucaults thoughts about discourse.

The Swedish system of environmental quality objectives is a so-called MBO, Management By Objective and has the purpose to guide the Swedish society towards sustainable ecological development. The system involves the whole society from the parliament and the government down to individual citizens. At the regional level, it is the county administrative boards that are responsible for the work with the system of environmental objectives. At the County Administrative Board of Västmanland County, it is the environmental unit who is in charge of work with the environmental objectives and they want input for how to improve their work with the environmental objectives, both internally at the Administrative Board and externally with external parties.The main purpose and goal of the study is to present the work of four other county administrative boards regarding their work with the environmental quality objectives and to identify external parties? opinions of how they want the County Board of Västmanland county to work with them in this matter.The work is designed as a case study of four county councils, where the environmental objectives coordinators at the four county administrative boards were interviewed about their work with environmental quality objectives.

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..

This thesis analyzes the expected profitability in land based wind power plants. The expected profitability is calculated on the basis of a wind power project in Vartofta, Falköping. The information required to calculate the expected outcome is then concentrated to this project, which is in this thesis called project Näs. In project Näs they plan to build three wind power plants, with each an effect of 2 MWh. These wind power plants are very capital intensive investments with a long and uncertain payback time.

Wind power is a growing energy sector in Sweden. However, it still represents only a small part of the total electricity production, about 0.7%. In order to create good conditions and to facilitate the establishment of wind power in Sweden, the government has for example, created a national centre for wind use. The objective has been to reach the governmental goal, which is an expansion of wind power by 10 TWh by year 2015 compared to the level in 2002. The Swedish electricity market was deregulated in 1996 which refers to the introduction of a competitive market in electricity production and trade.

In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.

Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.
