We are working on the development and design of an approach to agents that can reason, react to the environment and are able to update their own knowledge as a result of new incoming information. In the resulting framework, rational, reactive agents can dynamically change their own knowledge bases as well as their own goals. An agent can make observations, learn new facts and new rules from the environment, and then update its knowledge accordingly. The knowledge base of an agent and its updating mechanism has been implemented in Logic Programming. The agent?s framework is implemented in Java.

Böcker, dagstidningar och lagrad information, t.ex. cd-skivor, fyller inte sin funktion som det självklara valet för en stor del i dagens moderna samhälle där det ska gå fort att få tag i uppdaterad information. Valet för många är Internet, där man kan få tag i aktuell information endast genom att par enkla musklick. Det är inte enbart för individen möjligheterna finns att ta del av den senaste information utan även för företagen. Företag kan enkelt nå ut med den senaste information om t.ex.

The purpose of this study is to examine what view librarians have on reading promotion for adults, in particular reading circles, and in which way earlier experiences, education and competence form this view. To what extent, if any, do perceptions of professional identity influence the interest to carry out some kind of reading circles for adults?Our study is based on qualitative interviews with librarians, both those in charge of reading circles in libraries and those who are not. As theoretical starting point we have used Andrew Abbott's work on theory of professions and Jofrid Karner Smidt's thesis on literary preferences and different kinds of mediation of literature. For our analysis we will also use earlier studies on the subject to place our study in a wider context.Our conclusions show that the librarians in our study have an ambivalent view on their profession and professional identity.

This report presents the results of the tests of data rate and signal strength that I have conducted. The tests have been performed in the municipality of Arvidsjaur, Sweden. The report also contains the conclusions I have drawn from the results as well as an introduction to radio and the technology used in the nets that have been testedThe equipment used is:LG G2 cellphone used to test Telias 3GHuawei b593s-22 3G/4G router used to test Tele2s 3G/4GMobile Broadband Gateway R-90 used to test Net1s CDMAThe data rate has been tested with bredbandskollen (www.bredbandskollen.se). The signal strength(RSSI) has been read in the configuration menu of the broadband routers as well as in the cellphone.The conclussions drawn:Net1s net appears to be more used compared to its capacity than the other netsTele2s net has a high and even data rate where it?s signal strength is sufficient.

Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.

The aim of this study is to examine the roles of the children?s librarian in a reading aloud context. To reach understanding in this subject, we have conducted interviews with four Swedish librarians working in public libraries whom are involved with reading aloud practices. Previous research shows that the reasons for reading aloud in libraries are diverse and plentiful. Such reasons can be to spread cultural experiences, help children develop their language skills and promote the library to the public.

This is a master degree thesis at Royal Institute of Technology (KTH) betweenÅngpanneföreningen and Programma. KTH is the examiner, Programma is the client andÅngpanneföreningen is mentor for this project.Programma has a product called TM1800 that has problems with EMC; the problem is thatthis product does only pass the CE-check with a small safety margin. This problem can besolved by reducing the radiation from the electric components in the product or by reducing offix base frame. In this degree thesis the focus is only on mechanical redesign.The main problems right now depends on the long distance between the screws, there is anisolating layer on most of the parts and the forces between the joints are too small. The mainfocus is to solve these three problems.The best solutions are when the whole base frame is more or less redesigned instead of onlyredesigning some of the connection points.

Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

Introducing a new type of IT-structure means a change that employees within an organization must adapt to. Today, many companies have implemented information technology in the form of Enterprise Resource Planning (ERP) Systems and find themselves in th so-called Second Wave stage where an after work is ongoing with continual improvement that involves changes that employees need to understand and act upon. To learn how to work with these recurrent misadventures is of importance because it is seen as a critical factor in order to take advantage of the ERP system and its benefits. To study this a study was conducted through personal interviews at Apoteksgruppen AB which a few years ago introduced a new ERP system. There the authors saw that employees learned in different ways depending on the position, and that the more responsibility this person had the greater freedom this person had to resolve their problems and therefore learned more effectively.

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.
