Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.

Current technology offers many possibilities for remotecommunication. Nevertheless, people with cognitive and communicativedisabilities have limited access to common communication technology like textmessaging via a mobile phone. This study is part of the project Text messagingwith picture symbols - a possibility for AAC users and people with cognitiveimpairments. Semi structured interviews were used to investigate three menand four women?s experiences of using Windows mobiles with adaptedfunctions for text messaging.

Title: Development and continuity: A new institutional case study of a Danish public library in changeAbstract: The purpose of this master's thesis is to discuss and analyse the relationship between the traditional core values belonging to the institution of the public library, and the development work that takes place at the institution. The thesis also investigates the relationships that influence the development work.By investigating a library that is considered progressive in its development work, our purpose is also to unveil alternative values that compete with the traditional core values. By illustrating the perception among seven staff members and the director at Aarhus Public Libraries, we want to illuminate the terms for development among public libraries. In addition to our interviews, an activity plan is studied.We base our study on new institutional theory which focuses on norms and values in an organisation. This focus helps us to understand the development work from a comprehensive view.Our study shows that the development work at Aarhus Public Libraries is taking place in a complex environment that consists of several different actors and different interpretationsof the traditional core values of public libraries.

Purpose: The purpose of this paper is to highlight three preschool teachers and three child nurses? views on the educational work tool pedagogical documentation and Reggio Emilia educational philosophy, often associated with pedagogical documentation. Preschool teachers and child nurses? are all employees under the same pre-school director, and works on three preschools located in the same area. The purpose of the selection of respondents is based on highlighting how far the staff describes the concept of educational documentation, and pedagogy of Reggio Emilia, and how far their statements are consistent with each other or not.Questions: The thesis is based on three questions;How does preschool teachers and child nurses? describe pedagogical documentation?How does preschool teachers and child nurses? describe the Reggio Emilia pedagogical philosophy?If there are differences between the preschool teachers and child nurses?, what could these mean for the pedagogical documentation in preschool?Method: The study is based on empirical data collected through qualitative interviews.

The law firm industry has during the last years met new demanding conditions and one tool to handle these new conditions has been to implement a Knowledge Management system. Large investments have been made in these Knowledge Management systems but the implementations have met many challenges from within the organizations.With a multiple study, based on interviews with Knowledge Management Managers included in a Knowledge Management network, this thesis aims to study the challenges with Knowledge Management and the underlying causes. The result, based on McDermott's theories shows challenges within technical, personal, social and management areas where the law firm need to shift a focus from Information to Knowledge Management, create a culture of trust and integration and use the informal powerbase.The causes for these challenges are found in the base of Mintzbergs theories of Professional bureaucracy where the Knowledge Management is affected by strong self-regulated individualist, a divided organizational structure and industry conditions..

AIMS AB is a Swedish company that develops and sells inertial sensor systems. A new product is under research which basically is an aided inertial navigation system where unwanted drift is eliminated. This can be done by integrating a GPS reciever into the system and fuse measurement data from GPS and IMU. Such a product is useful in racing, where engineers always are searching for the optimal performance and the shortest lap times. Today the only feedback the engineers and mechanics get from their work is the driver?s comments and lap times.

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Overall aim of this master?s thesis is to describe and identify perceived barriers in Swedish businesses within solar energy field and analyze, based on four theoretical viewpoints, how these barriers can be handled. In other words how can the barriers be overcome or eliminated to better succeed in the commercialization process? The method applied is qualitative in which data has been collected through phone interviews originated from seven Cleantech businesses which operate within solar energy. Furthermore this thesis has a descriptive- and an explorative purpose.

I have, with a point of departure in two case studies; the artist, curator and scientist Andreas Gedin and Maria Lind, curator and director of Tensta konsthall, contextualized with a couple of respondents; the freelance curator, writer and editor Power Ekroth and the freelance curator and artist Carl Michael von Hausswolff, conducted a field analysis on curatorial and artistic practices. I have applied key concepts in order to conduct the analysis.Furthermore, the case studies and the respondents have been placed in a contemporary artworld. These components have been related to a contemporary historical segment of the artworld. This in turn, has been related to older, international cicumstances of change and various conditions in the two subfields. I have suggested certain a proximity in the artistic and curatorial practices.

Watching television (TV) has been given a new meaning, you don?t have to book a specific time, a specific date if you don?t want to miss the program you were planning to see. In Sweden now days we can watch TV in lot of different ways, whenever we choose to do so. In this thesis I attempt to explain and document the process of shaping a tvformat, the development and adaptation to a time when the TV medium is in a change. Plus a look at how the television audiences relate to their use of it.

This is a study about the communication interaction in the context of the reference work at some public university-libraries and some private company libraries in Gothenburg and Borås. The primary purpose of the study is to investigate the communication interaction in a library situation. The second purpose is to deepen the knowledge, understanding and to establish what is important in this communication. Focus has been on how the intermediaries communicate and how she or he perceives this communication. The intermediary needs to manage the communication with all the different patrons and different information needs of the patrons.

The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.

The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.
