Undersökning av optimeringsalternativ för elektrostatlackering
This report describes a thesis done at the Jönköping University of Technology. The aim of this thesis was to create conditions to optimize an existing automatic electrostatic coating system by changing the technology for dispensing lacquer. To select the technology, a study of different dispensing techniques carried out which concluded that the piezoelectric membrane and electrostatic atomization are the most interesting techniques.In order to perform tests with dispensing techniques a demonstrator has been optimized. The controller and PC software of the demonstrator has been programmed to be able to send out PWM signals that control the dispensers. An adapter card was designed to control the piezoelectric membrane and a steering link to the electrostatic atomization has been developed for PWM signals up to 500V.The work has laid ground for a demonstrator where further testing of the dispensing technologies can be performed..
Informationskompetens i det svenska och bayerska gymnasiet : En jämförande analys av det svenska och det bayerska gymnasiets läro- och ämnesplaner
This study is a comparative study of the occurrence and function of information literacy in the curricula of the Swedish and Bavarian Gymnasium and investigates the occurrence of the term ?information literacy? and shows through what other linguistic means the notion of information literacy is expressed in the curricula. The study also wishes to analyze how the notion of information literacy manifests itself in the different school systems. Relevant textual passages of both curricula are compared to each other through the theoretic lens of Bruce?s phenomenographic model of information literacy.
Från varuperspektiv till servicelogik : ett arbete om rollförändring och öppenhet på webben
This study focuses on the transfer between a product-oriented to a service-oriented perspective regarding marketing activities in companies due to the development of information technology. It illustrates how this very transfer has been, and can be, contemplated through the eyes of organizations working with marketing in a digital world on a daily basis. Technology has turned several industries - their price-setting, communication channels and supplying possiblities - upside-down. This turnpoint brings out a new way of observing and working with marketing. Therefore, we find it interesting to gain a better understanding of how actors within industries where the turnpoint is a fact observes marketing, and how this service perspective can be seen in their various organizations and daily.

With the help of this table, it is possible to get an idea about what technology is the most suitable to use when constructing a specific web portal.
Fyra uppdrag om människokroppen för grundskolans senare år
Recent studies show that the knowledge in and understanding of science, technology andmathematics of Swedish junior high school and high school students is decreasing. As a resultof this the Swedish government has initialized several studies, research and reforms. One ofthe theories for teaching that today is seen as effective is the socio-cultural perspective and itsdescendants, including scientific inquiry. Using the pedagogy of the socio-cultural perspectivefour assignments regarding the human body was constructed for junior high school studentsattending summer research school in the summer of 2008, hosted by AstraZeneca. Theassignments follow a structure (goal of assignment, preparations, experiment and follow-up)inspired by the concept of NTA ? Naturvetenskap och Teknik för Alla (Science andTechnology for everyone).
"Det som står i Internet kan också stå i en bok, så då måste det ju vara sant": En undersökning av Komvuxelevers informationskompetens
The information flow of today is endless and the advances in information technology astounding. In today's information society it is of utmost importance not only to be able to find the right information but also to evaluate the information. The expression ?information literacy? is not a new one but it has never been as pertinent and essential as today. Information literacy is however not something which is easily and swiftly achieved.Swedish youth education is based on problem based learning in which the students are expected to research for material, evaluate their finds and use their skills to produce a good written or oral presentation.
Teknikens betydelse i en lärande miljö : Datoranvändandets betydelse i undervisningen för elever i åk 7 i en Stockholmsförort
We live in a society that is constantly developing and where technology is getting a more major roll. The school is a very important part of our society and should therefore develop in pace with the surrounding society. Having this in our thoughts we decided that our purpose for this case study should be to study the importance of technology in a learning environment for seventh graders in a specific school. To be able to find this out, we have used constructivism and sociocultural perspective on learning. We have gathered our empirical data for the study through participant observations and a focus group interview.
Police Science - expansionen av ett kunskapsfält : En studie om vetenskapligt gränsdragningsarbete i 1930-talets Chicago
In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.
Varför Klass? Att studera ojämlikhet ur ett statsvetenskapligt perspektiv
This thesis contains a wider discussion on the analytical framework of classstudies in political science. The purpose is to put class into the light of a usefulmethodological and theoretical tool when it comes to studies on inequality and political,as well as scientific approaches and explanations to why people have awide range of differences in how they pursue their lives. It is my ambition to discusshow class relations can be theorized and explained within a given context, aswell as in society as a whole. I see the complexity of this field as a resource to enhancethe epistemological as well as the empirical discussions within the politicalscience scholars..

Minimizing acts of violence through telephone-linked care: an
automated telephone system for outpatients in forensic
psychiatric care
Achievements within the fields of computer- and telecommunication technology have led to a revolution when it comes to managing information. These achievements have made it possible to offer new services in healthcare, especially in telemedicine. New technology has become a complement to traditional care, thus partly compensating for insufficient time and resources. Telephone Linked Care (TLC) is a telecommunication technology that enables automated dialog counselling and monitoring of patients in their homes. During the last two decades numerous randomized controlled studies with TLC have demonstrated improvement among outpatients with chronic and health behaviour disorders.
Militära ?mobil-appar? : Den militära nyttan med kommersiell teknik för militära ändamål
The transformation of the Swedish Armed Forces is bringing about major changes in many areas. Indirect fire is one capability affected by these changes. Financial savings, a shrinking organization and higher eligibility requirements mean that fewer soldiers will gain access to exclusive high-tech support resources such as the JAS 39 Gripen aircraft and the ARCHER artillery system. This thesis aims to examine whether access to indirect fire capability can be increased through the use of civilian products and communication networks. Technology development in the civilian mobile communications area is exponential and nations such as the USA, facing challenges similar to those of the Swedish Armed Forces, devote substantial resources to research and development.
