The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

Skolans styrdokument ställer krav på att lärare och elever ska använda digitala medier i undervisningen och digital kompetens ses som en nyckelkomponent för ett livslångt lärande. Syftet är att analysera interaktionen mellan lärare och elever under problemlösningssituationer i matematikundervisningen med smart-board som medierande artefakt. Studien har ett sociokulturellt perspektiv.Empirin är insamlad genom video-observationer och studien är öppen och kvalitativ. Empirin består av fyra filmade och transkriberade sekvenser som innefattar fyra olika elever och hur de arbetar med problemlösning med smart-boarden som medierande artefakt. Empirin är analyserad utifrån EMA-modellen, som bygger på idéer från John Deweys pragmatiska filosofi.Resultatet visar att interaktionen styrs av läraren eftersom att det är läraren som styr över talutrymmet, men även vilka elever som ska vara delaktiga i interaktionen.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart grids and future meteringsystems and tariffs.

This study concerns design thinking and how to achieve usability when designing applicationsfor smart watches. The study's focus is on interaction and design for online auctionapplications such as Ebay and Tradera. After studying usability and design for devices withsmall screens, guidelines and design principles for interactive systems, we developed apaperprototype for an auction application. The prototype was used for testing our intervieweeswhile observing and asking questions. After collecting the data we analyzed the responses andfeedback on our prototype and combined the results to previous studies.

Syftet med detta examensarbete var att utveckla en utrustning för test av larmsystem uppbyggda med CareTech?s Smart Call-produkter. Testutrustningen ska kunna upptäcka problem i kommunikationen mellan dessa enheter. Den ska också kunna mäta matningsspänningen till enheterna under en viss tid och visa om spänningen har varit lägre eller högre än tillåtna värden..

Background: IT-security is included in the concept of information security, which considers all the security of handling information within an organisation. Good IT-security is about finding the right level of measurement, however, it is hard to implemement new IT-solutions in an organisation, particularly within the health care field, where sensitive information are handled daily. Lately the Swedish government, together with county- and city council, understand the importance of IT and health care. Carelink, an organisation of interest, is working actively for the presumption of benefit by using IT within the health care field. During spring 2006 the Swedish government introduced a national IT-strategy.

Syftet med examensarbetet är att få ökad vetskap om vad elever och lärare har för erfarenheter och inställningar till informations- och kommunikationsteknik, IKT, i skolan samt hur elever upplever att de lär genom IKT. För att uppnå syftet har vi utgått från följande problemställningar: Vad har elever och lärare för erfarenheter av Smart ? board och dator i skolan? Vad har elever och lärare för inställning till Smart ? board och dator i skolan? Hur upplever elever att de lär genom Smart ? board och dator? Vi har utfört en kvalitativ undersökning på en skola i skolår 4. Vi har intervjuat elever och lärare samt utfört observationer. I arbetet tas olika teoretikers syn på barns utveckling och lärande upp.

This essay deals with the influence of leadership on student use of Smart phones as an ICT tool at after school care. I use a qualitative, hermeneutical method that departs from two stories. I also use qualitative interviews with both structured and unstructured questions. My reflections and interpretations are, through the interviews, complemented by my colleagues? views of the use of Smart phones and how that is affected by how the activities are managed.

En tydlig trend i spelindustrin är spel som kan köras på flera olika plattformar. Detta är även känt sommultiplattform-spel. En av de nya spelplattformarna på marknaden är Smart-TV, det vill säga TVapparatermed internetuppkoppling och dedikerade operativsystem. Att anpassa eller utveckla nya speltill denna plattform är dock problematiskt, då den medför en helt ny användningssituation (?The 10 footuser experience?).Denna studie handlar om hur mobilspel kan anpassas till att köras på Smart-TV.

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

Syfte: Syftet med studien är att undersöka hur SMART Board användas som ett pedagogiskt redskap i undervisningen inom årskurs 1 till 5. Detta med utgångspunkt i ett specialpedagogiskt perspektiv, där SMART Board sätts i relation till möjligheten att vara ett verktyg, samt del av ett förebyggande arbete, som eventuellt kan underlätta inlärning och/eller skolgång för elever som kan möta olika svårigheter i skolmiljön.Teori: Teorianknytningen i studien utgår ifrån det sociokulturella perspektivet.Det sociokulturella perspektivet grundas i att sociala konstruktioner påverkar den verklighet vi lever i och uppfattar, samt att kunskap är en konstruerad representation av verkligheten. Studien anknyter även till det specialpedagogiska forskningsområdet där det är studier omkring det preventiva arbetet som står som forskningsobjekt.Metod: Undersökningen utgår ifrån en kvalitativ studie där observation och intervju används som metod för att förstå människors beskrivningar och uppfattningar. Observationsstudien är en minietnografiskt inspirerad studie och intervjustudien utgår ifrån den kvalitativa forskningsintervjun. Resultatet bearbetas och beskrivs utifrån en tolkande ansats.Resultat:Resultatet från undersökningen påvisar att SMART Board kan vara ett pedagogiskt redskap, som kan underlätta inlärningen för elever.

This report describes a bachelor thesis work performed at the cloud storage company CloudMe in Linköping, Sweden. The storage service provided by CloudMe allows users to access their files seamlessly from multiple units at the same time. In the cloud there is storage provided for contacts, calendar and e-mail, which is data nowadays normally used by smart phones.Exchange ActiveSync is a protocol developed by Microsoft which, among much more, provides functionality to synchronize the previously described data. This protocol is supported by the smart phone developers and the ability to synchronize over the exchange protocol is implemented in products by default. Due to this fact it would be preferable to implement support for synchronization from CloudMe to phones over this protocol.
