Konstruktion och programmering av lerduvekastare

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.

Klarluftsturbulens (CAT) : gÄr det att undvika?

Turbulens Àr ett vÀderfenomen som har orsakat mÄnga olyckor och incidenter. Speciellt farligt Àr klarluftsturbulens eftersom fenomenet ej Àr synligt för blotta ögat, samt att det kan uppstÄ mycket plötsligt. Mycket pengar och resurser har lagts ned för att ta fram system som skall kunna detektera och automatiskt rapportera turbulens. Denna uppsats beskriver kortfattat hur nÄgra av dessa system fungerar samt hur systemen skall bidra till att piloter lÀttare skall kunna förbereda för eller undvika turbulens. Uppsatsen beskriver system för prognostisering, detektering och automatisk rapportering av turbulens med tyngdpunkt pÄ klarluftsturbulens..

Levnadsvillkor och ontologisk sÀkerhet: Psykosocial utveckling och kulturell underbelastning i komplexa sociala system

Utvecklingen frÄn jordbruks- och industrisamhÀllet till det moderna informationssamhÀllet har medfört stora förÀndringar i de sociala systemen vad det gÀller grupprocesser och interpersonell dynamik. Sett ur ett komplexitetsperspektiv kommer de tÀtt kopplade agenterna i de tÀtt kopplade systemen att uppvisa interaktionsmönster, som skiljer sig frÄn tidigare historiska epoker med dynamiska processer unika för tidevarvet. Syftet med detta examensarbete Àr att, via en litteraturstudie, beskriva och problematisera individens förutsÀttningar för identitetsbildning och ontologisk sÀkerhet i komplexa sociala system. Resultaten visar att komplexa sociala system kÀnnetecknas av sjÀlvorganisering, som kan resultera i att komplexa strukturer/egenskaper vÀxer fram pÄ en högre nivÄ. Den semi-autonoma agenten kan Àven konceptualiseras som ett komplext system, i sig, som pÄverkar, och pÄverkas av, de mÄngfaldiga komplexa sociala systemen.

Analys av nivÄproblematik i drÀnagetank pÄ Ringhals 1

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

Mjukvaruplattform för riggstyrning

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Prestandaundersökning och ÄterstÀllning av degraderade RAID-system

Denna B-uppsats tar upp prestanda och ÄterstÀllning mellan tvÄ vanligt förekommande mjukvarubaserade RAID-system. Mjukvarubaserad RAID har blivit mer och mer intressant eftersom det Àr ett billigt och bra sÀtt att skydda sig mot hÄrdvarufel pÄ hÄrddiskar. Tidigare har det inneburit prestandaförluster om man inte har anvÀnt en hÄrdvarubaserad RAID kontroller men med dagens snabba processorer Àr det inte lÀngre sÄ. HÄrddiskar gÄr för eller senare sönder och för ett RAID-system som ska vara igÄng tjugofyra timmar om dygnet Àr det viktigt att det Àven dÄ fungerar med bra prestanda. Denna undersökning visar hur mycket sÀmre prestandan blir under sÄdana omstÀndigheter samt hur lÄng ÄterstÀllningstid man kan förvÀnta sig pÄ ett datorssystem uppbyggt av delar för hemmabruk.

The purpose is to look at Outline from four different aspects: 1. In what way is the system constructed looking at classification theory, 2.

Mean value modelling of a poppet valve EGR-system

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

Reducering av effektförbrukning i inbyggda system med Linux

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

Riktlinjer för mobil applikationsutveckling

Marknaden för mobila system har utvecklats enormt snabbt de senaste Ären. Idag Àr det ett omrÄde med en allt större omsÀttning och det har vuxit fram som en helt ny gren inom Software Engineering.

Valet av system kan vara helt avgörande för om man hittar rÀtt mÄlgrupp av konsumenter och dÀrmed kan generera tillrÀckligt med omsÀttning för att driva lönsam utveckling av applikationer. Det rÀcker inte att enbart kolla pÄ vilket system som har mest anvÀndare eller vilket system som genererar mest omsÀttning, utan man bör noggrant övervÀga de förhÄllande som gÀller för just den applikation som ska utvecklas. Genom att följa denna guiden och övervÀga de olika faktorer som vi har sammanstÀllt sÄ kan man som utvecklare göra ett val som Àr baserat pÄ aktuella marknadsundersökningar.

UtvÀrdering av miljöbonus IP-lantbruk :

The Dairy business is changing a lot because of some scandals in the agricultural area for example the BSE crises in Great Britain. Because of the scandals the food industry and the farm association have created a certifying system; IP-Sigill Swedish standard system. We contacted SkÄnemejerier as they have been successful in the certifying area. They asked us if we wanted to do a study in the certifying area of dairy farmers. At SkÄnemejerier they gave us most of the literature in the area about certifying. The result of the study, is that we have taken up the most common remark?s. The most frequent remark is journal over routines in management of dairy cows on daily basis. Another remark of the study is that the frequency of the remarks decreases with greater production..

Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

?Tillvaron [...] vidgar sig? : Alberte ? en Ny kvinna i genusomskapandets tid

This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.

Microstrip Solutions for Innovative Microwave Feed Systems

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.
