This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.

This paper analyzes Allt, Martina Lowden's novel from 2006, from a media discursive perspective. The theoretical framework consists of Michel Foucault's discourse analysis, Friedrich Kittler's research on hermeneutic reading, and N. Katherine Hayles's studies of pattern?randomness controlled meaning production. Various examples on how communication technology influences the narrator?s act of writing illustrate the medial discourse surrounding the body of Allt.

Processindustrin har möjligheten att ta steget in i en ny utvecklingsfas där teknik kommer att spela stor roll. I och med att teknik allt mer stödjer mobilitet öppnas möjligheten för processoperatörer att på valfri plats kunna övervaka och styra tillverkningsprocessen. Med denna rapport presenterar författaren sin empiriska studie på en högteknologisk fabrik. Studiens fokus ligger i betydelsen av processoperatörernas mobilitet och hur den framträder i deras arbete. Studien visar att mobilitet för operatörerna på fabriken är en del av deras yrkesutövande och väsentlig för att kunna styra tillverkningsprocessen.

Vi har gjort vårt kandidatarbete på en webbyrå i Stockholm som heter Boman Communication. Där har vi gjort en databasdriven webbplats i flash och asp. Webbplatsen är ett komplement till en kurs som heter EBM. Kursen EBM hålls av myndigheten SBU som i sin tur är en kund till Boman. Målgruppen för EBM och därmed också webbplatsens målgrupp är bland annat professorer och läkare inom medicin och vård.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

The explosion of information technology has given users direct access to an ocean of information. Increased availability puts increasing demands on the ability of students and researchers to search for, filter, and structure information. In response, the role of the research library has shifted from being primarily an information resource to being an educational resource with a focus on teaching users what is known as information literacy. This thesis is a study of user-education at the Karolinska Institute Library KIB, the largest medical library in the Nordic countries. KIB has invested significant resources in developing user-education, and has a full-time user-education developer and a formal pedagogical platform for user-education.

Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.

Elektronikföretaget Mobiltech AB i Karlskrona, Blekinge, var i behov av en ny webbapplikation och visade sitt intresse i att låta oss utveckla en ny mer dynamisk lösning åt dem. Deras mål med systemet var att de själv enkelt via ett webbadministrations gränssnitt skulle kunna redigera alla information på deras företags webbsida. Systemet som helhet omfattas av kategorier, informationssektioner samt en erbjudande panel. Som via en lösning av kod struktur och design, som vi från grunden byggt upp för att passa de behov som finns, bildar en administrerbar sida. Vi utvecklade projektet genom att använda oss av PHP5 och MySQL5. Dessa tekniker är något som vi har använt oss av genomgående under våra år på utbildningen. Vi valde dessa tekniker efter att ha övervägt fördelar och nackdelar samt undersökt andra lösningar som vi känner till.

In this essay I discuss and analyse if we can witness any signs on regional dimension due to regional representation from our elected representatives in the five constituencies Malmö, Blekinge, Norrbotten, Uppsala and Stockholm. Two seperate terms of office between 1991-94 and 1998-2002 has been compared. In political science there has been much debate about the relationship between voters and their elected. By measuring each and everyone elected representatives in the work of produce introduced bills towards their own constitiency during both terms I have tried to see if there is an occurence of a regional dimension.The theory that´s been applied is based on geographical representation where one might aspect that central metropolitan areas and peripheral regions is somewhat over-represented in legislatures. By using a method of comparison between the five chosen constituencies and theirs elected representatives I have come the the conclusion that there is a weak tendency that this might be the case seen to a regional dimension perspective..

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

Detta arbete har två olika delar som behandlats på olika sätt. Inledningsvis har dagssituationen för teknikämnet i grundskolan kartlagts. Bland resultaten återfinns ett samband mellan behöriga tekniklärare samt de lärare som själva valt att undervisa i teknik, och intresset för ämnet teknik. De behöriga tekniklärarna återfinner vi framförallt i de större städerna. I den största gruppen lärare som undervisar i teknik, No lärarna, har endast tio procent valt att undervisa i ämnet själv.

Idag väljer många företag och kommuner att placera data i molnet istället för på en lokal server, detta medför nya problem som tidigare inte varit aktuella. Datainspektionen har påpekat brister i hur två kommuner använder molntjänster för att lagra personlig data då de ställer sig tveksamma till molnleverantörernas hantering av data samt insynen till molnleverantörerena. I detta arbete kommer det undersökas hur den svenska personuppgiftslagen fungerar när data läggs ut i en molntjänst. Resultatet av uppsatsen kommer även visa på de olika säkerhetshoten som finns i molnet och se vad säkerhetsexperter säger för att ta reda på om kommuner och företag är medvetna om och uppmärksammar samma hot. För att ta reda på detta har intervjuer genomförts med en svensk molnleverantör, företag som utvecklar tjänster mot molnet, privatpersoner som nyttjar molnet och experter inom säkerhet från Blekinge Tekniska Högskola, BTH. Resultatet av studien visar att det är svårt att se om en amerikansk leverantör uppfyller de svenska lagarna för personuppgifter, det visar också att det är teoretiskt möjligt att anlita en svensk leverantör och uppfylla lagen. Det har även visat sig att den största oron gällande molnet är bristen på kontroll av data..

 The aim of this essay is to examine if the Swedish Major labels are moving towards making their catalogue available on different platforms rather than their traditional distribution of music. The new technology has really stirred things up for the major labels and file-sharing has been a problem for a long time. The labels have a history of fighting new formats instead of embracing them and listen to what their consumers actually want. We have found that the majors now are in the leading edge of music distribution due to technology and that is a first. We have focused this essay on if the consumption of music has changed the distribution of it or the other way around and found that people have changed their ways of consuming music over the years and the labels have always been forced to adapt.

The communication with government and municipality through Internet has in-creased during the last couple of years. Therefore we have chosen to focus our bachelor thesis in this particularly area and the needs for usable web services for the citizens. In this bachelor thesis we are studying a increasing group users, namely elderly citizens. During the study we have analysed E-governments ser-vices usability through usability tests. The combination of conversations and meetings with individuals, observations of interactions and literature studies give us the opportunity to explore the users needs.
