In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

This thesis is based on design theory about how to build an application for the mobile platform, a scientific analysis and an application for grocery shopping and meal planning. The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.

Något händer när ny teknik gör intåg i klassrummet där undervisning, studier och lärande i olika ämnen står på schemat. I nästan varje elevs ficka finns idag en populär artefakt, mobiltelefonen. Att telefonen påverkar skolkulturen är förståeligt. Men hur anser lärarna att elevernas användning, kommunikationsrutiner och strategier för studier och lärande påverkar undervisningen och attityderna till skolarbetet? I skolan har man traditionellt alltid använt artefakter som myndigheterna har tillhandahållit, exempelvis böcker, penna och papper.

Mobiltelefoni har blivit allt vanligare i dagens samhälle och konkurrensen mellan operatörerna har ökat. Det är då viktigt att operatörerna har ett stabilt och kvalitetssäkert nät. För att åstadkomma ett kvalitativt nät är planeringen bakom viktigt. Idag sker planeringen med hjälp av ett framtaget predikteringsprogram, TEMS Cellplanner, som är ett beräkningsprogram. TEMS Investigation är ett program som används då kontroller av nätet görs ute i fält.

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

This thesis examines history of the subject of mechatronics and innovation. The main reason tostudy mechatronics from a historical point of view is that it has never been done to a greater extent before. An overview is justified because various definitions have been used over the decades, but nowadays the subject has become more established. Focus in this thesis is mainly on development of the subject of mechatronics at Royal Institute of Technology in Stockholm. Innovation is the other aspect of this thesis.

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

Idag besöker vi inte längre webbplatser enbart via datorer, utan även mobiltelefoner och surfplattor. För att göra interaktionen på en webbplats användbar via flera olika plattformar blir det allt vanligare med responsiv anpassning. Denna utveckling ställer högre krav på den grafiska formgivaren som bör ha god kunskap om de plattformar som designen tillämpas på för att nå högsta möjliga användbarhet. En grafisk formgivare ska alltså förstå vad användbarhet innebär och hur denna kunskap ska tillämpas i designen. Kandidatarbetet undersöker vad som definierar användbarhet och vad grafisk design bidrar till i skapandet av responsiva webbplatser. Utifrån litteraturstudier i samband med en produktion i form av en responsiv webbplats, presenterar vi i detta arbete våra metoder för hur den grafiska designen ska uppnå användbarhet oavsett plattform. ---- We no longer visit websites solely by using computers, but also mobile phones and tablets.

This thesis explores the effect of using a new media in the marketing mix. SL, in cooperation with Clear Channel, has covered the outside of an entire carriage, 46,5 meters long, in an underground train with an advertisement for a company. This new form of advertising has taken place in the Stockholm Underground system during spring 2005. The five companies participating in this project are MTV, the Aftonbladet/Sportsbladet, Eniro 118 118 SMS, Heinz and the Gallerian.An empirical study has been carried through to survey the motive for companies to market themselves, their brand and product/service, by using the outside of a carriage on an under-ground train as a gigantic, mobile bill¬board. The study also investigates the commuters? attitude regarding this form of advertising.

The aim of this Master´s thesis is to explore how public libraries in a successful way can work in projects with young people. It intends to point out different factors that in a legible way affect the accomplishment and outcome of the project. Another purpose of the study is to uncover the various approaches existing within the projects towards young people and to find out why it is seen as important to work with youngsters, considering the hard work that it requires and the reluctance of the young to visit the library. The examination is based upon eight different and fulfilled projects. Information about these has been received through project descriptions, project reports and documents describing applications for economical benefits.
