Fordonsgas från deponier : en potentialstudie i Biogas Öst-regionen

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.

Utveckling av tjänster för ett mobilt medium

The mobile revolution is here to stay, and today most people have (at least) one cell phone at home. Some even a PDA (Personal Digital Assistant)as a complement for the simpler tasks at the office, e.g sending e-mail, word processing, browsing the Internet etc. Many business have also given the employees the opportunity to do some of the business tasks inbetweeen customer visits with the help from a cell phone or PDA.Despite all this, the so called Internet connected mobile revolution is often mentioned as a big failure. Maybe because the people in general tended not to use the new technology as much as the companies predicted. This could be because they still haven't learned how it works, or just don't seem to have the need for services provided.After a couple of failures in the development process, almost every cell phone has support for mobile Internet today.

Working with spontaneous communication : A workplace study on the use of technical tools and social praxis in the collaborative work at two smaller design-companies.

This paper presents the results of a workplace study of two smaller companies in the design industry. The core issue has been to investigate the companies use of technical tools and to what extent social praxis influence the daily work. The methods used are based on a qualitative analysis of interviews and observations. Various kind of work procedures, such as verbal and computerized, have been identified, but the most important occurrence was how spontaneous conversations between employees required certain flexibility, since the actors repeatedly were required to change focus and quickly perceive different information. For that reason, a thesis has been defined regarding how the use of spontaneous communication put an indirect need of a flexible working environment and also how this lead to more significant participation and exchange of information, as well as more awareness at the companies..

Lärplattformar : En fallstudie av lärplattformarna vid Umeå universitet

Umeå University currently uses two Course Management System, Moodle and Sakai (Cambro). Both Moodle and Sakai are based on open source code and are today the two more popular choices among Swedish Universities. They both have different strengths and weaknesses both from a technical perspective and a user perspective. This can create problems for a course responsible/teacher when it comes to planning the course structure at a distance course but also when planning the course structure on a campus course that uses a Course Management System. With this as my starting point my formulations of questions become:How do the Course Management Systems that Umeå University uses differs, both from a technical perspective and user perspective?What possibilities is there in the Course Management Systems to use a different Course Structure?Is there a noticeable difference on the view of Course Management System of teachers and students at different departments?The purpose with my essay is to create a basis that course responsible/teacher can use to plan the course structure.

Legionella i tappvattensystem. Förekomst och förebyggnade-en redogörelse.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

Energianvändning i sjukhuslokaler. Analys baserad på verksamhetsrelaterade nyckeltal

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

Ränteavdrag i företagssektorn : - Skatteverkets förslag till förändring

In Sweden the main principle is that interest expenses are deductable. The rules of limitations on interest deduction are exemptions to this main principle. The provisions, which came into force on the first of January 2009, have been inserted into Chapter 24 secs. 10 a ? e Swedish Income Tax Act (ITA).

Energibalansberäkning

Abstrakt -  As energy prices rise, energy-saving in buildings is becoming increasingly important. By applying different construction and installation technologies, to new buildings the energy consumption can be reduced effectively, compared to similar existing buildings. These technical measures are often an investment in the long term and will reduce energy costs significantly. The purpose of this report is to show how to reduce energy consumption in a small house. It is presented in this report that both building's technical saving arrangements (the sealing of a building) and an installation technical arrangement (changing from the F-system to the FTX-system) would reduce energy consumption in newly built detached houses, if compared with a similar existing house but without these technical measures. The report presents also detailed calculations showing how much energy an existing 2-storey house, built in the year 2007 in Eskilstuna, consumes and how much energy would be saved if these corrective measures were applied to a new building. It is also reported how much money would be saved each year over a 10 year period if the measures were applied. The results show that both solutions are a good investment in the reduction of energy consumption and hence the cost involved. Keywords: energy, heat energy, infiltration, FTX-system, free temperature effectively. .

Vindkraftsplanering i skogsmark

The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent Technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.

Kvinnor om IT ? högskolestudenters förhållande till informationsteknik

Information technology (IT) penetrates more and more areas in the community. The Commission for Information Technology is of the opinion that the use ought to be widespread but states that this is not yet a reality. Differences exist between groups, e.g. between women and men. The purpose of this Master's thesis is to examine how female university students enrolled in two different programmes experience and use IT and to compare this with society's picture of the relationship between IT and women.

Aktörer och artefakter : Ett samtida perspektiv på bibliotek och automatisering

This bachelor thesis examines the activities and values associated with automation and technical development at four Swedish research libraries. It does so by applying textual analysis to annual reports and job advertisements from the respective libraries. The study also questions whether some assumptions of automation have changed or remain over time, and includes a short historical discussion in relation to the contemporary analysis. As an added perspective it introduces the methods and philosophies of French sociologist Bruno Latour. The author reflects on the merits of Latour in research of library automation.

Genus och informationsteknik ? En studie av kön/genusrelationer bland bibliotekspersonal

The purpose of this study is to examine sex/gender relations amongst staff in public libraries who have taken part in projects related to information technology. This is done through e-mail surveys and telephone interviews with staff who have participated in the development of the two library websites Mina bibliotek and Biblioteket.se regarding their experiences. The theoretical basis for the analysis is two gender theoretical perspectives with reference to technology. The first perspective is represented by Yvonne Hirdman?s theory concerning the gender system, in which women and men are kept apart and in which there is always a hierarchy where men are higher up, and Hanna Westberg-Wohlgemuth?s theory concerning sex marking of job-tasks.
