This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.

The background to this thesis is the impact of information technology on libraries and librarywork. If information technology causes changes in the tasks and work of libraries, thenlibrary organisations should also change. It is important to engage and inform the staff if suchchanges are to succeed. This thesis investigates the notions about library tasks and librarywork among eight "middle-managers" at Linkopings universitetsbibliotek.The investigation is based on interviews and then analysed with Soft Systems Methodology(SSM). By identifying the "Weltanschauung" of the staff, the thesis tries to create logicallydesirable and culturally feasible models of systems relevant to the situation at Linkopingsuniversitetsbibliotek.

The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.

This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.

The aim of this study is to analyse and investigate a rather new field of LIS studies, i.e. link analysis which is a part of webometrics. Webometrics has been described as the quantitative study of web based phenomena drawing on bibliometric or informetric methods. Link analysis has its counterpart in citation analysis within the field of bibliometrics. The questions the study investigates are if webometrics can provide LIS with new knowledge and if there is a place for webometric studies in LIS research.

Syftet med denna uppsats var att undersöka hur väl webbplatsen för Karlstad Universitetsbibliotek möter studenters behov på mobila enheter, samt huruvida de anser att en biblioteksapp skulle utgöra ett behövligt komplement i framtiden. Uppsatsen riktar sig främst till Karlstads Universitetsbibliotek men kan även tänkas vara av intresse för bibliotek vid liknande lärosäten.För ändamålet upprättades två prototyper, varav den ena representerade befintlig webbplats på mobiltelefoner, medan den andra utgjorde ett exempel på hur en biblioteksapp skulle kunna se ut. Under jämförelsetester fick sedan studenter genomföra en grupprumsbokning och söka upp en elektronisk resurs i respektive prototyp samt besvara enkätfrågor.Av resultatet att döma finns ett intresse kring en biblioteksapp bland Karlstad Universitets studenter, då de gärna vill ha tillgång till bibliotekets tjänster på sina mobiltelefoner även om befintlig webbplats upplevs som krånglig på denna plattform. I ?OneSearch? (dvs.

Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

The aim of this study has been to investigate whether people with siblings that have disability have been personally affected when making choices about their studies and careers based on their upbringing with their siblings. The method chosen was qualitative data and consists of six interviews with people who are familiar with the chosen problem area. In conclusion, our results do not show a link between choices of study in relation to the sibling's disabilities. However a link was found between career choices, many choose to work in the area of health and well-being. This link was also found in literature we have researched, people living with disabled siblings have chosen careers and jobs within health and well-being..

The Swedish tax on income for persons who are unlimited liable to tax is based on his domicile and double taxation treaties between Sweden and other countries are based on his residence. In order to determine a person?s tax liability, the dwelling or home is of vital importance to determine where a person has his domicile and residence.For a person who has moved from Sweden, to be unlimited tax liable here, there must be an essential link. This link can be through previous residence in Sweden, the person is not a permanent residence in a foreign country, in possession of housing for year-around-use or in possession of house property.Sweden has concluded double tax agreements with other countries for the reason to prevent double taxation on the same income. When a taxpayer may be regarded as a resident in two states, the situation must be resolved to avoid that double taxation will arise.

TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.

The aim of this thesis is to compare two time periods in thehistory of the university library in Lund and to see whatsimilarities and differences can be found. The two timeperiods will be 1883-1900 and 1933-1950. The methodsused to achieve this will be comparative method with theactor- and structure model and document analysis. Thesubjects that will be analyzed with these methods will bepersonnel and the facilities. The two questions I will try toanswer in this thesis will be: A) What similarities anddifferences can be found concerning the personnel and thefacilities in the two time periods? B) What is therelationship between the actors and the structureconcerning the personnel and the facilities like in the twoperiods?A brief background of what took place in Sweden, LundUniversity and the university library of Lund itself duringour two periods is provided.
