Mechanization of Swedish agriculture started in the beginning of the twentieth century, to be able to have more animals without raising the number of employers. The horse business has not by far kept up with these cost savings solutions. Cleaning out stables and feeding horses are the most time-consuming tasks in horse stables today. The most common way to clean out the stable is still by shovel and wheelbarrow. The clean out process can easily be mechanized through semi- permanently beds with movable walls between the boxes so that the litter can be removed by a tractor or a loader.

This report is the written part of a bachelorthesis on the computer engineering program atUniversity of Halmstad. The project was a cooperate project that where done together withFree2move Holding AB. Free2move is a company with eight employees in Sweden and four inMalaysia. The company is today developing Bluetooth modules and RFID chips. The market forthis kind of products is growing very rapidly, last year it grew 71 percent.

This thesis for the Master of Science degree was performed at Oppunda Electronics AB. The assignment was to further develop an existing prototype of a dispensing equipment. The dispensing equipment doses a kind of glue, bonding which dentist use to mend teeth. The dispensing equipment is adjusted to dose 12 micro litres of bonding. With the dispensing equipment SafeBond Electronic the user can reduce the bonding consumption with approximately 50 percent.

The Swedish Processor Findus contracts approximately 500 pea producers annually to secure the company?s supply of green peas for human consumption. A production contract, which has had roughly the same design for decades, regulates the relation between Findus and the pea producers. Agriculture is typically a risky business. The main sources of risk in agricultural production are production risk and price risk.

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Basen för denna studie har varit observationen av att antalet återlämnade/återtagna familjegravplatser ökar. Orsaker kan vara en ökad mobilitet samt att enklare gravskick som minneslunden efterfrågats mer. Dessa familjegravplatser har traditionellt upptagit största delen av kyrkogårdens yta och det väcker nu frågor kring hur man ska kunna finna nya sätt att använda dessa ytor. Syftet med arbetet har varit att skapa kunskap och verktyg för att på ett bättre sätt arbeta med en kyrkogård i förändring. Tillvägagångssättet har varit kunskapsinhämtning, fallstudie, skissande som metod och reflektion.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat Processor in Västergötland.

The dairy market will change importantly in the coming years. The quota system, which has regulated the European dairy production, will disappear in 2015 and the European dairy market will then be importantly affected by the volatility characterizing the dynamic of world prices. Besides this, the global demand of dairy products is expected to increase due to the growing world population. Farmers in countries such as the U.S. and New Zealand, when compared to Swedish farmers, show greater familiarity and experience with risk management tools.

Detta examensarbete har gått ut på att med hjälp av vibrations- och temperaturmätningar göra ett system för slitageestimering av stridsfordon. Denna rapport är en av två delar som ingår i detta projekt. Projektet är utfört vid Land Systems Hägglunds anläggning i Örnsköldsvik. Utrustningen som tagits fram är tänkt att vara en liten och billig utrustning som monteras i alla fordon för att under drift lagra hur stora påfrestning fordonet utsatts för. Utrustningen är uppbyggd kring en mikroProcessor i form av en digital signalProcessor.

In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood. The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.

Idag är en ny minoritetsgrupp, döva med cochleaimplantat (CI), en växande grupp. CI innebär att en elektrod, som stimuleras av en yttre hörapparatsliknande Processor, opereras in i hörselsnäckan. Detta ger bäraren en god ljuduppfattning och relativt goda möjligheter att utveckla talad svenska. Tidigare har teckenspråk varit ett mer eller mindre självklart språk för döva barn, men nu ifrågasätts allt oftare om CI-opererade barn behöver teckenspråk bredvid talad svenska.I den här studien undersöker jag om det finns skillnader i konnektivtäthet hos tre grupper: en- respektive tvåspråkiga med cochleaimplantat och en normalhörande, enspråkig kontrollgrupp. Tidigare forskning visar att ju äldre man blir desto mindre konnektorer markerar man i sina texter.

Magnetlager bygger på att med magnetisk kraft få rotorn att sväva så att den aldrig kommer i kontakt med statorn. Minimalt slitage och oberoende av smörjmedel hör till de största fördelarna med magnetlager. Marcus Granström har i ett pågående examensarbete visat att det är teoretiskt möjligt att bygga ett magnetlager. Marcus Granström har tagit fram en Simulinkmodell över processen inklusive regulator. Vidare finns flera olika tänkbara regulatorer föreslagna.Detta examensarbete är en fortsättning på Marcus Granströms examensarbete och utgår från de modeller som tagits fram.

For att noggrannare kunna bestamma SOC (State-Of-Charge) och SOH (State-Of-Health) i AtlasCopcos batteridrivna mutterdragare har en litteraturstudie over de vanligaste metoderna gjorts.Utifran litteraturstudien valdes en metod for att mata SOC och tre metoder for att mata SOH. Foratt metoderna ska kunna appliceras i verkligheten kravs att vissa kriterier uppfylls. Da batterietladdas ur med hoga strompulser far matningarna inte oka serieresistansen fran batteriet.Dessutom har verktyget en Processor i sig och darfor far inte strommen brytas for matningen.Matningarna far inte heller pa annat satt paverka atdragningen eller stora anvandaren.Grunden i arbetet ligger i att oka forstaelsen om litium-jon batterier genom att studera batteriersuppbyggnad och bakomliggande kemi och fysik sa som termodynamiska- och kinetiskasamband. Som en fortsattning undersoks vilka fenomen som orsakar kapacitets- ochenergiforluster i cellen. Utifran den kunskapen gors en ekvivalent elektrisk modell som forklararcellens beteende nar den laddas ur.I metoden for att mata SOC har det undersokts hur val vilospanningen mellan atdragningarnastammer overens med SOC.
