The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..

The youth of today grow up with all the new ways to communicate that new technology provides. A lot of young people chat on the Internet. Adults often lack experience and knowledge about this way to communicate. This is a study of teenagers and adults values and views on teenagers online chatting. It focuses on area of use, meaning and effects on young people.

The purpose of this study was to investigate whether social counselling via chat conversations could meet the criteria for a professional conversation, and how the six social workers who were interviewed felt that it had affected the profession and the clients who are seeking their help.Communication, professionality, power, roles and regions are the key topics of this study. A hermeneutic approach has not only influenced the interviews but also the content analysis that was used to encode the results.The interviews revealed that the chat conversations was a successful tool but not entirely without difficulties. The initial contact making between the client and the social worker favours the client, since she/he remains anonymous and that was the main advantage of the method. The biggest concern however was that in the anonymity it is not possible to report cases that the social worker are obligated to. The changing of forum does not necessarily affect the professionality but due to the faceless chat conversation an entire dimension of communication disappears because the loss of body language.

Ten years ago the public computers with Internet access were introduced in the public libraries. The purpose of the public computers was to give the possibility of searching information. Along with the Internet came also communication media like chat and e-mail. This type of communication was a new function for the libraries and the reactions among the librarians were mixed. It has been a source of big frustration and attempts to block it has not succeeded.

This thesis presents a new way of providing library users with reference services, namely chat (text based digital reference service in real time). Our research questions focus on the role of reference service, a comparison of chat reference to other reference forms, and the interest for real-time, digital reference. Our literature review covered the areas of digital reference and reference theory, the results of which showed that an ongoing debate hardly exists among Swedish librarians on the topic of reference work. We interviewed librarians from the three different Swedish chat reference projects existing at the time of our study. Most interviewees were very positive about chat reference.

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

Title: Nätdejting för olika åldrar (Netdating for different ages)Author: Henri NekmouchePurpose: The purpose of this study is to investigate what influence the medium Internethas had on building up relationships between people who have dated online, and tocompare two different age groups.Method/Material: In this study the author has conducted personal interviews with sixpeople who all have experienced Internet dating, and had their first contact with agirlfriend/boyfriend online. The questions asked were designed to help answering thepurpose of the study.Main results: This study shows that in general there is a positive view of Internet datingamong both groups. They appreciate the opportunities it provides, as they get to knowthe other persons personality first. Even so, it should be noted that they still tend to be abit ashamed to talk about Internet dating, and some don?t want to be associated with it.The communication pattern tend to be pretty much the same among both groups.

Detta examensarbete syftade till att utveckla en tredimensionell virtuell miljö, där användare kan konversera och umgås med folk från hela världen. Miljön skall vara åtkomlig via en webbplats och vara kopplad till Lovemates, en chat utvecklad i Macromedia Flash 5.0. Examensarbetet bestod av följande delar: • Undersöka vilket webbläsarplugin som var lämpligt att använda till en sådan applikation. • Utveckla Lovemates3D med hjälp av valt plugin. Uppgiften löstes genom att söka på Internet efter tänkbara webbläsarplugin, jämföra dess för- och nackdelar med varandra och välja ett av dessa som plattform vid utveckling av Lovemates3D.

My paper deals with SMS and IM language's impact on students' language in school. Text messaging and instant messaging involves several simplifications and abbreviations for the user to be able to write quickly and short but in the same time have made them understood by the recipient. The spelling, punctuation and use of capital letters are also of a secondary importance when writing via the text chat. My purpose with this paper is to investigate the prevalence of SMS and chat language in student texts, using students in the senior level. My respondents were asked to answer a questionnaire and write a text to a picture.

The new technology brings new opportunities for the language. The language, which is used when chatting or messaging, is full of linguistic devices, which facilitates writing and saves time and space. The purpose of my investigation is to find out if the chat- and- messaging- language is affecting the students' way of writing in school.To find out about this I have examined 79 essays written by students in grade 9 during the national test 2006. I have also to found out if the occurrence of these features differed between boys and girls. In addition, I have let the same students who have written the essays answer questions regarding their chatting- and messaging- habits.The conclusions I have attained through my investigation shows that 58 % of the students are using features which are typical in chat and messaging language.

Mjukvara i datorer styr många viktiga funktioner i dagens samhälle och används i stor utsträckning för att kommunicera men även för att styra utrustning. För att mjukvara ska fungera tillförlitligt behöver den byggas korrekt och testas utförligt. För att uppnå tillförlitlighet kan en byggserver används för att automatiskt bygga och testa mjukvaran. Den här rapporten beskriver hur en prototyp av ett övervakningssystem för byggservrar skapats. Systemet sköter övervakningen genom en övervakningstjänst som hämtar information från en byggserver av typen CruiseControl.NET [10] och presenterar informationen på en webbportal.

Större kommuner och industrier använder alltmer automatiserade processer för tjänster och rutinerså som kundcenter och felhantering. Flexeurope AB är ett företag med flera års erfarenhet av auto-matiserade processer och arbetar med att definiera, visualisera, konstruera och optimera processer.Företaget utvecklar även ett webbaserad IT-system för processhantering, kallat flexiteBPMS.Inom en kommun eller industri arbetar ofta flera handläggare, ibland uppemot hundratals, med atthantera ärenden i processer. Detta ställer krav på att handläggare kan kommunicera med varand-ra. Effektivare kommunikation där handläggare snabbare får svar innebär effektivare hantering avärenden. Marknaden har till följd av detta uttryck önskningar om att möjliggöra en form av realtids-kommunikation kring ärenden i flexiteBPMS.Med detta som bakgrund har det här arbetet undersökt, planerat och genomfört en integration av enXMPP-baserad chatt med flexiteBPMS.

The aim of this thesis is to study different aspects of the public libraries' investment in public access computers connected to the Internet. What level of accessibility can be found at the surveyed libraries concerning the number of computers open to the public, as well as chat and email services? What activities have been taking place with the computers in focus, and what have the goals of these activities been? Is there any control of content, and what aspects of the Internet are, if that is the case, subject to censorship. And how do the governmental policies relate to the surveyed libraries' intentions and activities regarding the Internet? In order to answer these questions, each main library in the 42 largest towns of Sweden was surveyed response rate: 100 %.
