Informationsfrihet och IT-användning i demokratifrämjande syfte

The potential of information technology as a means to invigorate democratic practise is constantly under discussion. Regardless of the differing opinions as to the most suitable way to utilise IT, there are certain democratic core values that have to be considered. One of these is freedom of information, defined by us as the right of every citizen to seek, obtain and express information. The aim of this study is to explore whether the use of IT as a means to enhance democracy can strengthen the citizens right to freedom of information. As an instrument for analysis we use an article by Jan van Dijk, professor of communication science.

Modellering av delvis kända objekt med hjälp av bilder

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

Går det att mäta blodtryck med fotopletysmografi och bioakustisk sensor i kombination?

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

Biosensorsystem fo?r o?vervakning av vattenkvalitet

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Hur uppnår vi god inomhusmiljö i förskolan idag?

Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

Framtagande av OEE-mall

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).

Att vara i en intensivvårdsmiljö - patientens perspektiv

The Intensive Care Unit (ICU) is a special unit for patients who is in the need for emergency life-sustaining measures and every patient has complex medical- technical equipment. The experiences of a critical illness and the needs of critical care are experienced in different ways. The purpose of this study was to describe the experiences from patients in the ICU and how this experience has an influence on the patients. The method was a study of literature with a qualitative inception based on eight scientific articles and the analysis of content has been inspired by Graneheim and Lundman (2003). The result of the study is presented by four categories: to loose the ability to make themselves understood, to be forced to adjust to the environment of caring, to have the lack of connection with reality and to be in an intensive care environment, The results showed that patients in the ICU are affected by the attitude from the staff, the equipment around them as well as the sounds and lights in the environment there.

Förpackningseffektivitet vid Volvo construction equipment
AB, Component division

Vid Volvo construction equipment AB, Component division i Eskilstuna, har nedväxling i förpackningsstorlekar genomförts som en del i en omfattande omställning mot Volvo Production System och Lean. Genom att producera med mindre satsstorlekar och hemtagningskvantiteter, vill Component division sänka sin kapitalbindning och bli flexiblare mot variationer i produktionen. Dessvärre påverkar nedväxlingen förpackningskostnaden till följd av ytterligare hantering, transport och administration. För Component division är det viktigt att få en god uppfattning om hur alla förpackningskostnader utvecklas med tiden. De vill i framtiden följa ett lämpligt nyckeltal för att se hur effektiva de är inom förpackningslogistik samt hur beslut och förändringar påverkar kostnaden.

Stöd i undervisningen på högstadiet : En aktionsstudie som ska klargöra en elevgrupps perspektiv

The aim of thesis was to, through a action research study and through individual interviews with five students, clarify their perspective on educational assistance in high school. The study shows that students prefer teaching in small groups outside of regular whole class because it gives the them access to the factors they consider crucial for a functioning support-time whit a skilled and dedicated teatcher, in a calm and safe environment. Moreover, the students claim the importance of technical equipment especially in the Swedish subject, but also in other subjects. Today the educational assistance varies from an outside-the-class teaching situation to a whole-class situation with teacher support as well as technicaal equipment. When the student were asked to describe the cinditions under which studies can be conducted with the whole class they tried to imitate the learning environment they have in a small group.

Funktionaliteten i skogsmaskiners GIS-system

Holmen Skog is currently using a GPS-program called TraktInfo, originally developed within the company. They are now planning to switch to a new GPSprogram or allowing the contractors to buy other programs available from the logging equipment manufacturers. To be able to offer this flexibility, Holmen Skog needs to obtain information about the features offered by the different manufacturers in their specific programs, and also when the manufacturers are planning to start selling programs adapted to the new standard called StanFord2010. According to the study, the manufacturers are hesitant to StanFord2010 and there has also been a lack of clear signals from the customers and clients about what kind of different new features to include in the programs. The feature most frequently used by forest machine operators today is the option to keep record of the harvester?s path by creating a ?log plot?. This feature was not used to its full potential however, since only one out of eight of the forwarders included in the study had computers that were compatible with the harvester?s computer.

A standardized method for evaluating trueness and precision of intraoral scanners ? in vitro accuracy

Bakgrund. En gyllene standard för att bestämma noggrannheten för intraorala scannrar existerar inte. Intraorala scannrars prestanda som ges av olika leverantörer är inte fullt jämförbara. Det finns ett behov att standardisera och ta fram oberoende försöksupplägg för att kunna jämföra intraorala scannrar. Mål. Målet med studien var att beskriva och utvärdera en ny metod för att bestämma noggrannheten av intraorala scannrar genom ett standardiserat in vitro testförsök och att använda metoden för att beräkna noggrannheten på en kommersiell intraoral scanner. Material och metod.

BIM i förvaltningsskedet - Nyttan för fastighetsägare

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Mätningar och analys av elnätet hos FHP, Basproduktion

This report is a degree project performed at Freudenberg Household Products AB, (FHP). The degree project comprises measurement and analysis of the power net at FHP Basproduction. The content is divided between one theory-part, one document- part with measurements and also conclusions and a list of measures to be taken. During the project the purpose and restriction change from a quality investigation to only concentrate on harmonics and finding the reason why they exist, and also to find a solution to the problem with harmonics. The measurements shows that the power net contains harmonics of different order and intensity.
