This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Sveriges ytstridskrafter hade länge en förmåga att hävda sig mot fiendens stridskrafter ute till havs på 1950- och 60-talen. Nedrustningsprogrammet av försvaret på 1960-talet innebar att teknikutvecklingen bromsade upp och flottans större fartyg kryssare, fregatter och jagare skulle bytas ut till en lätt flotta med små snabba enheter. Detta resulterade i att flottans taktik anpassades till ett tillbakadraget uppträdande längs med kustbandet och inom skärgården. Svenska officerare bevittnade på när Sovjetunionen rustade upp och utvecklade nya vapen och fartyg med robotar av högsta kvalité i Östersjöområdet. Detta hot medförde att officerarna i flottan ville satsa på ett långräckviddigt vapen för att bli mer jämbördig mot fiendens styrka ute till havs.Resultatet blev en svenskutvecklad sjömålsrobot, Robotsystem 15 (RBS 15), som infördes i marinen i början av 1980-talet.

With this paper the aim is to find out whether there are any differences in how five students from the north part of Africa structures their tales in comparison with the Nordic tale "The emperor?s new clothes". The purpose is to look at how the genre pedagogy can be said to relate to these differences. What happens to the "deviant" structures?Based on literature and research on the subject, I have concluded that there are certain patterns of how a tale "should" be structured based on Western standards.

The study was conducted on 72nd company at Livgardet in order to find out what motivators makes the soldiers stay. The material in the essay is based on an interview with soldiers from the 72nd company. The motivators are then categorized in the model Employee Motivation: A Powerful New Model. The model is based on human drives and I used as a tool for the analysis to identify lack of motivation in a working place. The study shows that the key motivators that make soldiers stay is: the opportunity to go on a peacekeeping mission and comrade/esprit de corps, the soldiers state that they will quit without these two essential motivators.

This is a study of the importance of culture for persons who are in their terminal stage of life. The purpose of my study is to find out if culture, particularly literature, can be a comfort for persons who are about to die. The study is based on interviews with people who are working in the palliative team at Norra Älvsborgs Länssjukhus (NÄL) in Trollhättan. It is also based on study of literature. It is literature about hospital library, culture in hospital treatment, palliative care, bibliotherapy and ?own stories? from dying persons.

As the environmental requirements on businesses increase from various stakeholders, the incentives for businesses to work more with environmental issues also increase. Historically, the requirements were focusing on companies with direct emissions from operations. Lately, the environmental impacts that occur indirectly as results of corporate activities have become more topical. Companies and organizations that mainly offer services often have a greater indirect than direct environmental impact. This is because they are affecting third parties, which in turn have a direct environmental impact.

This project investigated the current market regarding wireless net and the communication between the tools used for diagnostics/maintenance and an embedded system.

This project investigated the communicational possibilities between a Smartphone and a Raspberry Pi and based on the results that emerged the conclusion can be drawn that BLE is a protocol with many beneficial applications within industrial IT..

The purpose of this paper is to explore how practicing teachers have included their education in their teaching profession. The five teachers who were interviewed expressed that they lack experience in dealing with administrative issues, conflict management, parental contact and how to manage stress. There has been prior research on how teachers perceive their everyday working lives. Those results showed that teachers are becoming stressed by not knowing how to handle certain situations.My results showed that the teachers were to busy so they created their own methods on how to deal with phenomena that the education have not treated or discussed. The interviews were analyzed with the help of two constructivist concept, authenticity and activity .Authenticity focuses on knowledge is created and constructed by everyday situations.

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

The capability to know what knowledge there is and where it resides within an organization is becoming increasingly important in the new knowledge-based economy. This paper takes on a practise-based view of knowledge in order to decide on a course of action for how to successfully implement knowledge management within a knowledge-based company. By considering all knowledge as more or less contextual and socially constructed, knowledge is divided into three dimensions depending on the degree to which it is tacit, namely: information, knowledge and skills. The paper then discusses inhibitors and enablers for transferring knowledge via these three dimensions respectively. The empirical findings are based upon a case study of Faveo. It is shown that Faveo, like most organizations, has til now focused on the collection of codified knowledge, i.e.

Specialundervisning och nivågruppering i matematik har inte så stor effekt (Bentley & Bentley, 2011; Giota & Emanuelsson, 2011) och vår skollag (2010:800) gör gällande att undervisningen ska ske inom klassens ram. Med detta som utgångspunkt designades denna studie. Studien genomfördes med 21 elever i år två under nitton lektioner. Syftet var att se om intensivundervisning med hjälp av strukturerad undervisning kan ge effekt på elevernas automatisering av additions och subtraktionstabellerna inom talområde 0-20. Studien genomfördes som en experimentell design med fältexperiment och metoderna i studien var deltagande observation, fältanteckningar och diagnoser.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
