This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.
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.
Dominerande affärsmodeller inom området informationssäkerhet
Computers together with Internet have been growing enormously, during the last
decade and the area of information technology has been growing in the same
speed. As long as the surrounding environment evolves, the business models must
within the IT-area, keep the same pace. So, how do business corporations handle
this change to attract customers? How do the dominant business models look
like? In many cases, they are apparently much the same. But what differences
can we see and what areas can be improved?
We have showed that the IT area isn?t just one, it consist of several segments.
Allt finns på Internet En undersökning om biblioteksanvändande hos studenter på Chalmers Lindholmen i Göteborg.
The purpose of this master's thesis is to investigate how the students at Chalmers University of Technology at Lindholmen in Gothenburg use libraries in their schoolwork. The empirical material consists of the answers of questionnaires that were handed out to two classes of students, on the second year of their education. To illustrate the topic there are a theoretical frame and examples of earlier studies. The theoretical frame is Limbergs texts that deal with for example information seeking and how important it is in all education. The earlier studies are about student's different ways of using libraries.
Experimentell jämförelse av Cassandra, MongoDB och MySQL
Context. Performance and resource usage is often an important factor for
database driven services. Depending on the purpose of the application, choosing
the wrong type of database may require
unnecessary hardware upgrades or replacements.
Objectives. This study investigates the differences in performance and resource
usage between
different SQL- and NoSQL-databases. The study is a comparison that focuses on
how the databases
perform in different applications.
Sufism inom den somaliska diasporan i Göteborg
The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.
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.
Datorspel för lekfull och interaktiv teckeninlärning: utvärdering och vidareutveckling av en prototyp
The aim was to evaluate and suggest improvements for the prototype TIVOLI (sign-learning via computer-based playful interaction). The game purposed to give children who need signing as augmentative and alternative communication enhanced signing skills. Three children in need of signs played TIVOLI at home during 4-5 weeks. Data contained parental interviews, Talking Mats interviews, assessment of signing competence before and after the evaluation period and game protocols. One game interaction per child was filmed.
Bakhjulsupphängning, fyrhjuling
Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.
Betongarbeten under vintertid : Fokusering på platsgjuten betong
This report is on concrete work during the winter and is implemented on Peab?s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting.

Utvecklingen av röstigenkänningsprogram under en treårsperiod
Detta kandidatarbete är utarbetat på Blekinge Tekniska Högskola under våren
2002. I utredningen har vi jämfört röstigenkänningsprogram under en
treårsperiod, program från 1999 och program från 2002.
1999 års test visade på programvaror med lång träningstid, enkla gränssnitt,
stor känslighet för bakgrundsljud och låg användbarhet. Vid arbetsstart
förväntade vi oss inte att hitta någon större förändring i användbarheten hos
dessa program 2002, då röstigenkänningsprogram inte verkar ha stor
användarskara.
Utifrån följande hypotes har vi genomfört arbetet: Vi vill med vår undersökning
bevisa att användbarheten inom röstigenkänningsteknologi inte har förbättrats
under perioden 1999-2002. Vi har för avsikt att med hjälp av test utförda på
program och demoversioner bevisa vår hypotes. I enighet med bifogad
testspecifikation har vi utfört testerna.
Många företag har utvecklat sina produkter och gjort dem bättre.
Informationsteknik och högskolan ? policy och verklighet
The main objective of this thesis is to examine the situation concerning information technology, computers and information resources for university students at a selection of universities, and their libraries, in Sweden. Another objective is to compare this situation to what is stated in policy documents on the subject, and if the size of the university matters regarding resources. The thesis starts with a discussion of several authors, Frank Webster, Paul F. Burton and Lars Qvortrup among others, and their views on the information society. These range from whether we are living in it, are in a transition period or are still in the Industrial Society.
En Kommunikations Illustration : Interaktionen mellan deltagare i ledarlösa samarbeten
Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.
