AO modulen

This master thesis has been written in collaboration with Science Park Jönköping and is based on a problem related to corporate innovation. Science Park Jönköping believes that there is an untapped potential in existing industry in the form of ideas that are never commercialized. These theories are also supported in the research in which other authors have perceived that the ideas and inventions which do not belong to the core business risk ending up in drawers. If more of these ideas could be spin-offs or other forms of enterprise instead of staying in the drawers it would lead to growth, both for companies and for the society in large.The purpose of the thesis work is to, based on the case Science Park Jönköping, analyze how science parks and incubators can support the commercialization of ideas that derive from industry, who otherwise had been left lying. The work began with a mapping of the Science Park Jönköping operations and the skills they possess, and then other initiatives that aim to commercialize more ideas from companies were examined.

Användartester inom webbutveckling : Är användartester nödvändigt vid utveckling av webbplatser?

The aim of this study is to get a deeper understanding about user tests as well as answer the question about if testing for users is necessary at all times. I've done a comparison between what the literature says, and what a company says, about testing. The tests that's been in focus in this study is prototyping and card sorting tests. Prototyping aims to give the developer feedback about the design and check if there are any obvious problems with the design. A card sorting test can be used to get input about how information architecture should be constructed.

Utvärdering av Near Field Communication och Certified Wireless USB: Säkerhet vid utveckling av applikationer

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

The Scientific Coach - Idrottsforskning i tränares vardag

Previous research has established coaches' important role in developing elite athletes (Durand, Bush, Thomson & Salmela 1996). Athlete enhancement and assisting athletes achieve ?peak performance? has been a major objective for elite coaches as well as sports scientists (Williams & Kendall, 2007) Despite this common goal, research also question whether sports scientists and the research they pursue really effects coaches knowledge and constitute a foundation for today and tomorrows athletic performances (Bishop 2008).  This study examined elite coaches? needs and use of sport science research as well as the interaction between elite coaches and sport scientists. Following interviews of ten elite coaches, content analysis revealed that sport science is both a formal and informal resource of knowledge for coaches. Development of athletes is seen as the main objective of research retrieval and personal and/or direct contact with the sport scientist is considered to be the best way to assemble.

Gamification som möjliggörare för att motivera användare av system för tillverkningsindustrin

Gamification är en strategi som använder spelmekanismer och spelkomponenter för att skapa motivation och engagemang hos användare av olika typer av system. Denna studie syftar till att undersöka om gamification kan användas för att motivera användare av system för tillverkningsindustrin.Studien har genomförts med en initial litteraturstudie och kvalitativa intervjuer med experter inom gamification samt utveckling av system för tillverkningsindustrin. Intervjufrågor har därefter ställts mot tidigare genomförd forskning, för att identifiera möjliga resultat.Resultatet av denna studie visar att spelmekanismer och spelkomponenter skulle kunna användas i ett system för tillverkningsindustrin, förutsatt att det finns ett tydligt affärsmål, mätbar och användbar data samt identifierade drivkrafter hos organisationens maskinoperatörer. Vidare har ett antal punkter identifierats som kan vara motiverande för en användare av system för tillverkningsindustrin:Möjlighet för operatörerna att följa utvecklingen i sitt expertområdeKartläggning av operatörernas drivkrafter, vilken därefter används för att förbättra operatörernas arbetssituation, med exempelvis mer givande uppgifterBelöningar som utdelas är matchade mot operatörernas preferenser, med syfte att vara mer effektiva som motivationsskapare.

Reglering av vridbord

This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

Utveckling av ett provtagningssystem för alkohol och aldehyder i fordonsemissioner.

A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..

Modellbaserad drivlinereglering

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

Testramverk för distribuerade system

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

Molnet och dess möjligheter och  utmaningar : En kvalitativ studie i hur molnet förändrar systemutvecklingsarbetet

As companies grow, their need for computing power will increase, which traditionally resulted in companies having to invest in more IT resources. Now, with cloud computing, companies can easily hire computer power over the Internet, on-demand. Cloud computing offers a highly scalable environment where companies can store data and host their services. This paper employs a qualitative study with interviews and literature studies to explore opportunities and challenges associated with cloud computing from a system developer perspective. The aim of the paper is to find out how cloud computing changes the conditions for system development. The paper contributes with four different opportunities and challenges that the system developer must handle to succeed in the world of cloud computing.

Kombinerat system för ventilation och rumsuppvärmning : Parameterundersökning i simuleringsmodell för takvärmesystem

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

Automatiserad Verifiering av Grafiska Ritare och Tranformationsutvinning

En grafisk ritare i flygande system måste under dess utveckling verifieras för att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara identiska mot referensbilder genererade av en fungerande ritare så ställer det krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att automatisera den processen är i högsta grad intressant för att minska kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan uppstå, däribland ett sätt att utvinna eventuell transformation mellan två bilder..

Att skapa ett enhetligt användargränssnitt : Användargränssnitt baserat på personametoden som koncept istället för empiri

Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.
