Kunskapssamhället och skolan - vilken framtid möter våra lärare, elever och bibliotekarier?

The essay concerns "the knowledge society", IT and the possibilities of school being changedto meet the future. The purpose was to reflect the ideas of researchers and authorities concerningwork and education in "the knowledge society" and to illuminate/shed light on theimportance of information technology in this connection, to map organizational and pedagogicalshortcomings in the current school system and the changes that can be needed, and to investigatehow these changes can affect teachers, pupils and librarians.The investigation, which was a text analysis of normative and futurist sources, was especiallydirected towards how modem information technology can influence education/teaching.The differences between researchers and authorities were most obvious in the view of theimportance of knowledge of facts and central control mechanisms for standards or grading.For the authorities, who were devoid of a thought out/carefully prepared and consequent viewof knowledge and by that also of pedagogics, the information technique was the foremostcause of a change in pedagogy. The researchers also perceived the possibilities of IT, butemphasized the importance of pedagogical innovations irrespective of the technology.

Småskalig elproduktion i Arvika

Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

One of the latest applications of Internet technology are intranet and extranet. I have asked myself the question how intranet and extranet can affect companies efficiency and competitive advantage. In order to answer this question I performed a case study at Ericsson and ABB.

Digital eller mänsklig service åt användare av folkbibliotek? En diskursanalys av artiklar ur fyra svenska bibliotekstidskrifter 2003-2004.

The aim of this Masters thesis is to examine the user service discourses in the field of public libraries that can be identified in four Swedish library journals. Also which underlying causes that control the discourses and the consequences of them are examined. Questions in this study are: which discourses can be found, what characterises them, what kind of different discourses concerning technology in society control the user service discourses and what are the consequences of them. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory. The method is text analytic.

Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

VISION SJÖSTAD : Flytande Bostäder

Floating housing is a concept gaining ground in Sweden. The dwellings are different in many ways from traditional homes, not only regarding flotation, but also several other technologies. The purpose of this thesis is to emphasize the qualities that exist in living on water. The ambition was to present a proposal for a floating residential area located in Jönköping, containing homes of varying sizes, and to present their technologies. In order to find inspiration and solutions studies have been made on existing floating homes in Stockholm and Kalmar, focusing on their technical and functional solutions.

Utvärdering av MK F1500 testutrustning

SAAB Support and Services, som är servicecenter för flygplanskomponenter, utför idag huvuddelar av sina mätningar manuellt, mätningar som ibland kan ta upp till fyra dagar. För att höja noggrannheten samt öka effektiviteten köpte de år 2007 in ett automatiskt testkoncept från MK Test systems.I examensarbetet har vi först undersökt den inköpta utrustningen.Sedan har vi tagit fram rutiner för kalibrering av utrustningen som klarar SAAB:s krav. Därefter har vi arbetat fram kravspecifikationer och instruktioner för hur utrustningen ska användas. Under arbetets gång har vi samlat in information för att kunna göra en utvärdering av hur lämplig utrustningen är att använda för att testa flygplanskomponenter.Arbetet resulterade huvudsakligen i tre st manualer som går igenom tre olika områden; kalibrering, kablagetest och ett standardtest för t.ex.paneler och styrboxar..

ENERGIANVÄNDING PÅ BYGGARBETSPLATSER : Analys av införandet av energieffektiva bygg­etableringar

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.

Det Intelligenta Huset : - En studie i hemautomation

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

Är det någon skillnad? : En kvalitativ undersökning om bibliotekariers uppfattningar om den användarstyrda förvärvsmodellen Patron Driven Acquisition.

This thesis is about new technology in academic libraries in the form of Patron Driven Acquisition. As libraries take part in the digital era, a new model of patron driven acquisition has emerged. This model gives users more influence over the libraries electronic book collection. The collection development model changes libraries traditional role in the collection development process, from collecting for the future to the present.The purpose of this thesis is to gain knowledge of what acquisition librarians think about the effects of PDA on the collection, the acquisitions role and the cost structure. The theoretical framework relies on Christensen?s theory about disruptive technology and was used to interpret outcomes of new technology in libraries and its staff.Five librarians from four different Swedish university libraries were interviewed using a qualitative semi-structured method to carry out the investigative part of this thesis.

Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

Lågenergihus : Att bygga energisnålt

A large proportion of the energy consumption is in the building industry and a large part goes to heating our homes and premises. In the developing countries' development now threatens the large consumption of energy in our earth's climate. It is in the West world that we must be good role models in terms of energy efficiency. One solution to reduce energy consumption for heating of buildings may be to continue to build low energy houses and passive houses, but it is also about rebuilding the buildings that currently have high energy consumption such as the old Million program Houses. These buildings will be standing many years and their energy consumption will not diminish over time by itself and energy prices will certainly not diminish in the future.
