The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Navigation är ett centralt begrepp i spelanvändning, trots att det ofta ses som ett nödvändigt ont. Det här arbetet intresserar sig för upplevelsen av navigation i två typer av programvara ? spel och nyttoprogram. Detta arbete går ut på att granska hur upplevelsen av navigation i programvara är beroende på användarnas förväntningar ? om användarna tror sig använda programvara för nytta eller för nöje.

The aim of this dissertation is the production of a landscape management document to protect and improve elements of biological, cultural and economic value found within the site at Tosthult. The study involves both analysis of the current grazing regime, comparison of today?s flora with flora collected in the fifties and a SWOT analysis of inhabitants? views on Tosthult?s landscape and neighbourhood. The resultant landscape management document applies to an area over 134 ha and is valid for thirty years. The proposal contains 26 separate management units, each with necessary information on the area, definition of management goals and the mix of management procedures to undertake.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

This study investigates how performance management in primary schools can facilitate learning, relating to theories of efficient schools. This is done through a qualitative study of the performance management systems in two public primary schools in Sweden. The schools selected were similar in all major aspects, except pupil grades, where there was a clear difference between the schools. The analysis revealed differences in how the schools handled the process of management by objectives, the professional development of teachers as well as routines, rules, and policies. We conclude that having a rooted process for management by objectives, professional development of teachers, and clearly formalized values, gives a school a good foundation to support a pupil's learning and development..

Background: The trademark is something that surrounds us almost all the time wherever we are. Studies show that brands are becoming increasingly more and more important and that it is important to have a strong trademark. This may be a reason for acquisitions. A business is carried out for various reasons, but usually it is to gain market shares or to get advantages in the market, such as a trademark can help with. A contributory effect on the market can be customer loyalty to the trademark.

Background: Budgets has always been a main factor for the management of organisations. Yet, lately has the role of budgets been increasingly questioned. But how is an organisation managed without budgets and what other alternatives can be used? And can these instruments work more effective?Purpose: The purpose of this essay is to describe how non-budget management distinguish compare to traditional management and how to design an effective non-budget system of management. Furthermore we intend to explain the reasons to such management and to present a model for how such a management can be performed.Research method: Empirical material has been performed based on seven interviews with persons within Svenska Handelsbanken.

The paper investigates the role of packaging within brand management of FMCG food companies and their attitude towards packaging. This study enhances the understanding of how FMCG food companies actually work and strive to work with packaging..

The aim of this report is to improve the fire safety at Hallsta Paper Mill in Hallstavik, Sweden. In order to do so large parts of a fire-protection management system for the paper mill has been created. The report begins with giving a general description of management structures and fire-protection management systems. An account is given for how management structures are designed, and how they should be implemented, maintained and updated. Thereafter follows a description of what routines and instructions should be included in a fire-protection management system..

This paper aims to outline leaders' experiences of managing consultants from their company's performance management system. The study was conducted by qualitative interviews with senior managers and HR professionals within a management consulting firm. The aim was to describe the company's performance management system, their consultants and the challenges of leading in this context. The theoretical framework consists of previous research in leadership, performance management and management consulting. Within these research areas the authors identify a knowledge gap in leaders' perspectives on managing top-talents with performance management systems in the management consulting industry.

Consumers today leave a fragment of information when they pay with their debit and credit cards. The aim of our work is to investigate ways to design a concept of a system in which digitally stored information that today is fragmented among several different holders, can be assembled into a system and made available to consumers. In our study of how a system for financial flow of information should be designed, we intend to study the present situation and the attempts made to alter it into a more informative reality. We intend to investigate the flow of information when a consumer pays by card, and the possible solutions regarding the design and transportation of digital receipts. A majority of the information of our digital consumption is today handled digitally.

Uppsatsens syfte är att utifrån ett New Public Management-perspektiv undersöka i vilken utsträckning visionsstyrningsmodellen i Halmstads kommun följer New Public Management och utifrån det undersöka vad det resulterat i. Uppsatsen grundar sig i en intervjumetod där ledande politiker och tjänstemän från kommunen intervjuats. Den teoretiska ansatsen utgörs av en New Public Management?teori grundad på olika dimensioner av New Public Management. Uppsatsens huvudsakliga empiriska material kommer från de intervjuer som genomförts.
