<p>The phenomenon of drag reduction by polymers in turbulent flow has beenstudied over the last 60 years. New insight have been recently gained by meansof numerical simulation of dilute polymer solution at moderate values of theturbulent Reynolds number and elasticity. In this thesis, we track elastic parti-cles in Lagrangian frame in turbulent channel flow at Reτ = 180, by tracking,where the single particle obeys the FENE (finite extendible nonlinear elastic)formulation for dumbbel model. The feedback from polymers to the flow is notconsidered, while the Lagrangian approach enables us to consider high valuesof polymer elasticity. In addition, the finite time Lyapunov exponent (FTLE)of the flow is computed tracking infinitesimal material elements advected bythe flow. Following the large deviation theory, the Cramer’s function of theprobability density function of the FTLE for large values of time intervals isstudied at different wall-normal positions. The one-way effect of the turbulentflow on polymers is investigated by looking at the elongation and orientation ofthe polymers, with different relaxation times, across the channel. The confor-mation tensor of the polymers deformation which is an important contributionin the momentum balance equation is calculated by averaging in wall-parallelplanes and compared to theories available in the literature.</p> / QC 20100706

<p>Finn upps ämnesverktyg är ett imponerande inspirationsverktyg för teknikundervisande lärare. Genom att identifiera och lösa ett problem, så får man eleverna att tänka i nya banor. Undervisningsmaterialet och lärarhandledningens upplägg, ger lärarna möjlighet att använda det i sin helhet eller bara välja ut enskilda delar. Men vilka erfarenheter har lärarna erhållit genom att arbeta med ämnesverktyget i undervisningen? Undersökningen genomfördes via en webbaserad kvantitativ enkät. Resultatet av undersökningen visade att eleverna lättare uppnått delar av skolans mål i teknik med stöd av Finn upps ämnesverktyg. En majoritet av lärarna instämde i att elevernas kvalitativa kunskaper påverkades positivt, vilket kunde leda till ett högre betyg. Dessutom intresserade sig flickorna mer för teknikämnet än tidigare forskning visat.</p>

I got a request from Eleiko Sport AB regarding them needing help with trying to improve one of their products. The following examination project includes the principal- and primary construction reports within trying to make some improvements and optimizations on a stand for Kettle bells. I have in this project both made my own proposals to the stands legs, proposals on how to strengthen the shelf and also made an optimization of the original Kettle bell-stand. In this report, the project goes from idea to being built and analyzed in Catia, including the creation of drawings and material definition.

The amount of electronics in vehicles is growing quickly, thus systems are becoming increasingly complex making the engineering of these software intensive systems more and more difficult. In particular, an architecture supporting the business goals is a prerequisite for successful design. In this thesis two case studies have been made including three automotive companies with purpose to investigate the key issues related to real-world decisions when developing Electrical and Electronic (E/E) system architectures in the automotive industry. The results show that many of the identified issues relate to non technical areas such as organization, process, methods and tools, and management. Examples of identified issues are the deficient understanding of the electrical system and software at management level, and the lack of a specific process for architecture development. To cope with these issues we suggest the following actions: Educate management, increase the use of structured decision making, improve the architecture development process, clarify responsibilities in the organization and clarify development strategies. As a possible solution to one of the suggested actions we have developed a method to evaluate how new functionality is successfully integrated into an existing architecture. Themethod is a combination of the Architecture Tradeoff Analysis Method, ATAM, and the Analytical Hierarchy Process, AHP. The method firstly supports a structured way of listing system goals, and secondly, it also supports the making of design decisions. / Business Oriented Concept Development of Electronic System Architecture and Platforms in Vehicles

<p>Det primära målet med examensarbetet var att utforma ett koncept på hur man kan göra flygtrafiken säkrare både på marken och i luften. Konceptet fick namnet ATSVIS, vilket står Airport Traffic Surveillance and Visual Information System. ATSVIS är tänkt att ge anvisningar om vad nya idéer och ny teknologi kan tillföra piloten och trafikledningen. ATSVIS avser även att automatisera och förenkla flygtrafiken, vilket skall leda till säkrare flygtrafik både i luften och på marken. Konceptet ATSVIS kommer att utformas efter egna idéer och från intervjuer med branschfolk. Huvudarbetet av examensarbetet kommer att vara att ta fram en simulator där man kan visa och pröva hur ATSVIS fungerar.</p> / <p>The primary objective with the thesis is to formulate a concept on how to do the air traffic safer, both on the land and in the air. The concept got the name ATSVIS, which stands for Airport Traffic Surveillance and Visual Information System. ATSVIS is intended to give instructions what new ideas and new technology can do, to allocate the pilot and the traffic management. ATSVIS also intend to automate and to simplify the air traffic. The concept is formulated after own ideas and from interviews with people in the flight industry. The central work of the thesis is a simulator in which one can show and to examine how ATSVIS functions work.</p>

<p>STOTP-M (SAS Component) har fått luftriggar från SAS-Braathens Stavanger och uppgiften är att iordningställa dessa och fasa in komponenter för provning.</p><p>STOTP-M har tidigare ej utfört komponentprovning i rigg och ska nu ta fram procedurer för dokumentation av detta. Som ett led i detta ska en databas arbetas fram där provaren kan lagra information från provning. Denna information ska senare kunna användas för att åtgärdsbestämma underhållet av komponenter. Åtgärdsbestämning av de nya komponenternas fel är i nuläget svårt då inget tidigare underhåll är utfört av verkstaden.</p><p>När en komponent kommer in för underhåll kan det vara svårt att direkt säga vad som är fel på den. Därför utför man en pre-test för att bestämma de åtgärder och reparationer som sedan ska genomföras.</p><p>Detta examensarbete syftar till att skapa en databas för lagring av detta testresultat samt utfört underhåll på komponenter. Detta medför att man i framtiden kan få en bra bild över vad som fallerar i komponenten beroende på vilken typ av reason for removal som har inträffat.</p><p>Utöver databasen har även en felanalys på tre luftkomponenter genomförts. Denna analys innefattar en felbeskrivning för olika typer av reason for removal, samt vad som måste repareras/bytas vid varje underhållstillfälle.</p><p>Resultatet syftar till att ge ett förbättrat underhåll av de tre analyserade komponenterna. Dessutom ska man i framtiden med hjälp av databasen på ett effektivt sätt kunna lagra och få fram information kring varje komponent, som i sin tur ska leda till en effektivare åtgärdsbestämning. Eftersom felanalysens inriktning är med avseende RFR så kan det ge en felindikation på komponenten redan vid incoming test, och med hjälp av databasen har man procedurerna för hela provningen.</p> / <p>STOTP-M (SAS Component) have received air-rigs from SAS-Braathens Stavanger and the task is to put them in use so different type of components can be tested.</p><p>STOTP-M has never before performed any component testing in air-rigs and is now creating procedures for documentation of this.</p><p>As a part of this work a database has to be created so that the person who is performing the tests can store the results.</p><p>This information will later determine the level of disassembly for different types of failures. To determine the level of disassembly for different types of failures is today very hard because the shop has never performed earlier maintenance of this kind.</p><p>When a component enter the shop it can be very hard to find the faulty parts that caused the failure. Based on this a pre-test is accomplished where you deside what actions to perform in the shop.</p><p>In this thesis a database is created where you can store the data from the pre-test and also the performed work on the component. This will in the future give a good image of what parts in the component that will break down depending on what type of reason for removal that have occured.</p><p>In addition to the database an failure analysis on three pneumatical components have been performed. This analysis includes a failure description for different types of reason for removals, and what actions to implement for each shop visit.</p><p>The results from the analysis will give a better maintenance of the three analysed components. In the future the database will in effective way store and supply information from all the components, which will lead to more effective measures.</p><p>Because the failure analysis is with consideration to reason for removal it will give the failure indications on the component already in the incoming test, and with the help of the database the mechanic will have the procedures for the test.</p>

<p>Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models. Model Based Systems Engineering (MBSE) is introduced to, in a structured way, support engineers with aids and rules in order to engineer systems in a new way.</p><p>In this thesis, model based strategies for aircraft and avionics development are studied. A background to avionics architectures and in particular Integrated Modular Avionics is described. The integrating discipline Systems Engineering, MBSE and applicable standards are also described. A survey on available and emerging modeling techniques and tools, such as Hosted Simulation, is presented and Modeling Domains are defined in order to analyze the engineering environment with all its vital parts to support an MBSE approach.</p><p>Time and money may be saved by using modeling techniques that enable understanding of the engineering problem, state-of-the-art analysis and team communication, with preserved or increased quality and sense of control. Dynamic simulation is an activity increasingly used in aerospace, for several reasons; to prove the product concept, to validate stated requirements, and to verify the final implementation. Simulation is also used for end-user training, with specialized training simulators, but with the same underlying models. As models grow in complexity, and the set of simulation platforms is expanded, new needs for specification, model building and configuration support arise, which requires a modeling framework to be efficient.</p>
