Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie
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.
Utvärdering av inomhuslokalisering med Bluetooth Low Energy
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.

En bibliotekshermeneutik : Om skrivandets förutsättningar i Martina Lowdens Allt
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.
Hur ser elevernas läs- och skrivvanor ut på fritiden?
My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

Riskbilder och kontroll av ungas IKT-användning: En fallstudie
The use of Internet by children and teenagers has become a special field of interest. Certain risks are associated with young peoples use of this media and national and international measures have been taken to assess and counter these risks.Library and informationscience have approached the subject of risks by looking at different software´s, so called Internet filters, that is used to control and censor the access to Internet based resources. In the USA, where public services and institutions that provide Internet resources to children and youth have started to require censorship of the Internet, a debate has arisen concerning the use of so called Internet filters.The theoretical basis of this master´s thesis is related to the conception of risk, gender and childhood. The focus of the paper lies on young peoples use of information and communication technology (ICT) and how risks associated with young peoples use of the Internet is constructed by different parties involved in supplying Internet resources. By means of a case study at a primary school in Skåne and at the company Netscan in Malmö.
Produktutveckling med hjälp och stöd för teknisk projektledning : - en kvalitativ studie av tre högteknologiska företag.
Due to an increasing global market with a growing competition and an escalating technologydevelopment the demands on companies today are increasing. To maximise the output fromtheir recourses they need to be more efficient. The research on product development and how toensure the efficiencies in the process are extensive and companies could by adapting andimplementing the result of this research use its benefits.This master thesis is made for Knightec AB with the aims that through interviews anddiscussions with three companies investigate, collate, justify and give proposals for productdevelopment process together with supporting methods and procedures for technical projectmanagement. Besides Knightec AB three other companies located in Sweden has beenparticipating in this study. Through semi structured interviews and discussions in focus groupsinformation from the three involved companies were obtained.

Ultraljudsmätare för bubbelfälla
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.
