ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

The purpose with the essay is to illuminate four former clients? personal stories about the meeting with the authority in the Swedish welfare system and the institutionalization theywent through. The questions being asked in the essay focus on communication, the relationship concerning power and the former clients attitude towards the institutionalization as a treatment. Four interviews were held with former clients who were institutionalized sometime between the ages of 15-25. The results were then analyzed by theories focusing on communication as a way to gain power and how social interaction may influence the individual attitudes towards authorities.

How effective is consumer power? Can consumers regulate corporate behavior?And if so is the case, could the mechanisms where consumers regulate corporatebehavior have any democratic value to contribute with? These are the questionsthat this master's thesis comprehends with. The purpose of this writing is toconstruct a theory of consumer power that is compatible with democratic theory,this in order to contribute to the ongoing discussion within the discipline ofpolitical science about the third democratic transformation. A discussion that hasbeen actualized due to the democratic deficit created by the growing corporatepower and the shift of power from state to private enterprises. Besides showingfor a parallel between the democratic mechanisms that exists in the relationbetween citizens and state on the one hand, and the consumers and corporationson the other hand, this paper argues that consumers do have a great potential inregulating corporate behavior towards a higher social responsibility andawareness.

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

This thesis examines Swedish filmmakers' modes of work and production within the Swedish film landscape. An introductory historical overview treats the Swedish regionalization since the mid 1990's. Political and economical aspects of producing films in various regions serve as a background for understanding the new generation of decentralised Swedish filmmaking, and the use of sound and music in contemporary film. The analysis consists of empirical studies; interviews with directors and producers, working with music for film and TV. Although the filmmaking perspective is in focus, composers and film scholars are heard as well.

AbstractThis paper is a comparative study of the final reports of the Norwegian and Danish power studies performed in 2003. While the Danish study found that democracy is thriving, the conclusion of the Norwegian power study was that democracy is in a crisis. The purpose of this paper is to find explanations to why the studies in two Nordic countries arrived at such different results.Methodologically, the paper consists of an ideological text analysis and critical analyses of the discourse. In order to study how the results of the power studies can differ so considerably, the following aspects have been surveyed; 1) external contexts (government inquiries); 2) work process (the researchers? background, role and co-operation); 3) the problem areas and themes studied; and 4) power perspectives.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

This project includes development of new packaging for dry spices and an investigation of how to automate the production line. The preliminary investigations show needs of an environmental friendly packaging possible to re-close. After screening for suitable materials three concepts were developed, a stand-up pouch, a plastic jar and a metal can. The pouch was excluded in a concept choosing process. In this process it was also decided to further develop the metal can concept.

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm. Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).

This is a master thesis work carried out at the Department of Energy and Environment atthe Division of Electric Power Engineering. The master thesis work describes the theoryof distance protection relaying in 130 kV meshed distribution networks. The main aim ofthe thesis was to construct an Excel application for calculation and documentation of thesettings for distance protection relays. The program is based on general methods forcalculating settings of the different zones for the distance relay and presents the settingsin simple graphics using quadrilateral characteristics.The reason for building an Excel based application is the great variety of distanceprotection relays in live networks. The manufacturers of distance protection relays makeprogram for documentation available, however, they are based on the typical settings forthe specific relays.
