MobileReader är en mobil RFID (Radio Frequency Identification) applikation. Syftet med denna applikation är att skapa en RFID-läsare som skall gå att bära med sig ute på fältet. I första hand kommer läsaren att kunna läsa passiva RFID-taggar på Lågfrekvens-bandet (LF) samt att vara anpassad för nyare mobiltelefoner av tillverkaren Sony Ericsson. Detta examensarbete resulterade i ett program avsett för en Atmel ATmega16 mikroprocessor. Mikroprocessorn tar emot data från en befintlig LF-läsare via ett protokoll vid namn Wiegand 44.

Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd bedöms ha tillräckligt pålitliga skyddsprinciper, vilket motiveras av dess oberoende från både hårdvara och operativsystem. Vidare undersöks hårdvaruskrivskyddet Image MASSter(TM) Drive Lock från Intelligent Computer Solutions (ICS). Några egentliga slutsatser gick inte dra av kretskonstruktionen, bortsett från att den är uppbyggd kring en FPGA (Xilinx Spartan-II, XC2S15) med tillhörande PROM (XC17S15APC).

SammanfattningDetta examensarbete har haft till syfte att ta fram nya metoder för automatiseradtestning och validering av information som skickas över CAN (Controller-Area-Network)i en tung Lastbil. Signalinnehållet realiseras i flertalet komplexa och distribueradesystem. En implementering har gjorts där loggad CAN-trafikdata från en HIL (HardwareIn the Loop) miljö automatiskt analyserats och testats.Testen har genomförts på två nivåer: funktionell och ickefunktionell. Där denickefunktionella delen har testat tidkrav på meddelanden med kompensation förtändningsstörningar. Dessutom har signalinnehållet testats för att finna ogiltigafelflaggor.

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

Tinnitus och Menieres sjukdom är båda dolda handikapp, som påverkar hörseln. Tinnitus är ett vanligt symtom, inte bara i Sverige utan även internationellt. Tinnitus definieras som en upplevelse av ljud i frånvaro av yttre stimulering. Menieres sjukdom är ett kroniskt tillstånd som drabbar innerörat och ger symtom i form av anfall med yrsel, hörselnedsättning, tinnitus samt lock för örat. Syftet med detta arbete var att beskriva hur tinnitus och Menieres sjukdom kan påverka patienten i det dagliga livet, samt hur sjuksköterskan kan agera för att dessa patienter ska känna trygghet trots sina symtom.

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.

Projektet genomfördes på Ingenjörsfirma Edman & Sjöberg AB i Filipstad. Syftet med projektet var dels att utreda möjligheterna med att använda sig av vattenhydraulik, men även presentera nytänkande lösningar för ingående detaljer av en hydraulcylinder. Kvaerner Pulping AB, som var kund, efterfrågade en enklare cylinder som fortfarande klarade kraven till låg kostnad. Önskemålet om nytänkande lösningar rörde främst hur kolvstången kan hållas ren från avlagringar samt att lösa genomströmningen i toppläget av rörelsen. Arbetet skulle mynna ut i ritningsunderlag för att senare generera en prototyp av cylindern.

The aim of this study is to examine which support the communities in Kalmar have to offer children who have witnessed domestic violence. The study also includes how social services justify this actions based on the childs needs. The study includes six respondents; four socialworkers, one head of unit at ?Alternativ till våld? and one manager at ?Barnahuset? in Kalmar. The method used in this study is a qualitative research approach with semi-structured interviews. The study concludes that children who have witnessed domestic violence seldom are known by social services, but when a child is recognized the social service use ?Alternativ Till Våld? or a general support. It also reveals that those children often have a lower priority when weighed against children who has been abused..

The purpose of this thesis is to explore how the internal information processing and management is carried out within a unit of Viskafors municipality. Furthermore, to explore and make recommendations of how the organisation can improve its internal information management. To get a full picture I have interviewed people at different levels of the organisation. The main findings showed that there was a dysfunction in the internal information processing and management. For example the study showed that the internal information did not reach out to the different parts of the organisation due to insufficient information processing.

In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

The aim of present study is to evaluate the work of the employees within the Addict Care field, how they experience their struggle as well as the significance of the interaction between the client and the employees. It takes a great deal of effort when facing individuals with alcohol ?and drug related problems. The focus should be on the occupational and individual qualifications, while there is legislation, regulations and ethical guidelines to be followed. Intending to comprehend these issues better several interviews were made with six employees within The Administration for the Social Services and The Addict Unit in Växjö area.

Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.
