Play is an important part of children´s everyday life, it is through play children develop. Play occurs a lot in kindergarten and in this study, the aim is to examine how play activities play is used in preschool teaching and the role of the teacher´s in the play. Video recordings of play activities done and qualitative methods (conversation analysis) has been used to analyze the video recordings. The results of this study show that play are widely used as a pedagogical tool in preschool. It is through play children develop.

This thesis is about adware, which is very popular today. The adwares are used to, among other things, down- and upload files from other users on the Internet. One thing that most users of such programs are not aware of is that many of the adwares contain spyware. These spywares install themselves simultaneously with the adwares. Two of the spyware features is to generate pop-ups in the web browser and to direct advertisment from the users web habits.

The report contains a comparison between computer based modeling of evacuation and evacuation experiments with large crowds. Crowd movement, behavior and management is examined, as well as the evacuation time. The conclusions in this report are based on observations made during the evacuation of a football ground (Swedish)..

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

Titel: Kommunicera rätt! ? En studie om kommunikation mellan systemutvecklare med kundkontakt och kund. Författare: Peter Johansson Oskar Hanson Handledare: Johanna Törnquist Examinator: Guohua Bai Problemområde: Anledningen till detta examensarbete är att problem som kan uppstå vid systemutvecklingsprojekt vanligtvis har sin grund i kommunikationen mellan systemutvecklare med kundkontakt och dess kunder. Exempelvis hör en systemutvecklingsgrupp och ett bageri till två vitt skilda yrkesområden och därmed pratar de ?olika språk?, vidare kan det skapas semantiskt brus i kommunikationskanalen som i slutändan kan leda till en felaktig kravspecifikation och de verkliga förändringsbehoven förblir oupptäckta. Hypotes: Examensarbetet baseras på hypotesen: ?Semantiskt brus[1] i kommunikationskanalen[2], otillräcklig negativ feedback[3] från sändare[4] och mottagare[5] och svårighet att hitta rätt nivå på samtalet med hjälp av kodning[6] och avkodning[7] ger upphov till en felaktig bild av kundens verkliga förändringsbehov[8] .? Slutsats: Alla delar ur Shannons kommunikationsmodell tillsammans med cybernetikens negativa feedback påverkar resultatet vid framtagande av kravspecifikation. Delar som både teori och respondenter tar upp är att som konsult måste denne ?kunna tala kundens språk?, hitta rätt nivå på samtalet, ge och ta negativ feedback samt undvika semantiskt brus i kommunikationskanalen.

The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations. At times when the electricity supply system is highly loaded, electricity is more expensive.

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

This master thesis is made of two parts. The first part concerns the method and results ofdesigning a motion control system for a piece of research-equipment called BIRGIT. Theequipment is made to be used for research on eyemovements. In the second part, a computermodel of a part of the balance organ in the inner-ear is developed. The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.

Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd Detta examensarbete reder ut arbetsprinciperna för olika typer av hårddiskskrivskydd; hårdvaruskrivskydd, mjukvaruskrivskydd, hybridskrivskydd och bygelskrivskydd. Slutsatsen av utredningen är att endast hårdvaruskrivskydd bedöms ha tillräckligt pålitliga skyddsprinciper, vilket motiveras av dess oberoende från både hårdvara och operativsystem. Vidare undersöks hårdvaruskrivskyddet Image MASSter(TM) Drive Lock från Intelligent Computer Solutions (ICS). Några egentliga slutsatser gick inte dra av kretskonstruktionen, bortsett från att den är uppbyggd kring en FPGA (Xilinx Spartan-II, XC2S15) med tillhörande PROM (XC17S15APC).

In the gaming industry, it has long been popular to combine genres with the aim ofcreating games that bring together the best of several worlds. However, there are stillmany unexplored combinations with good potential.This report addresses the planning and development of a game prototype that combinestwo game genres, turn-based and real-time strategy. In addition to presenting the results,the report also discusses the di culties that were encountered and how they were handled.The prototype contains a working combat system and a basic AI. The prototype ismodular, which means that it is easy for an end user to extend the game with extra content.Most elements that were considered important from the two genres were implemented, butthere is still room for improvement and further development.The result is evaluated by means of quality assurance, a process that is commonly usedin the gaming industry. The response has been generally positive, which indicates thatthe combination has potential and should be explored further..

Syftet med studien är att undersöka och belysa synsätt på datoranvändandet som pedagogiskt verktyg i förskolan ur pedagog-, barn-, föräldra- samt skolledarperspektiv, det vill säga ur olika aktörers perspektiv. Forskning om datoranvändande i förskolan är marginell, varför ambitionen med studien är att i någon mån bidra till kunskap inom området. Ljung-Djärfs avhandling Spelet runt datorn - datoranvändande som meningsskapande praktik i förskolan har använts som inspirationskälla då delar av hennes resultat har legat till grund för våra frågeställningar: Vilken syn har aktörerna på datorn som ett pedagogiskt verktyg i relation till andra förekommande aktiviteter? Hur ser aktörerna på datorns tillgänglighet som val i förskolans verksamhet? Hur uppfattar aktörerna datorns relevans som pedagogiskt verktyg i förskolans verksamhet? Studien har en kvalitativ ansats i form av en fallstudie och har genomförts på en förskola i Mellansverige med hjälp av intervjuer, enkäter samt observationer. Resultatet pekar på tre synsätt på datoranvändandet som pedagogiskt verktyg i förskolan ? en kompletterande aktivitet, en konkurrerande valmöjlighet och ett verktyg i lärande.

One of our reasons is that we think the subject usability is interesting, is that we think it is an important. Usability is maybe the most important element when you develop or choose a system because it can save money for the companies and give the users a more delightful and better work environment. The aim of the investigation is to find out if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. The objective of our investigation is to show if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. In our case we will try to see if Karlshamns AB:s recently implemented web portal is more useful than their previous application (Movex with interacting programs) One thought with the report is to give the system developers a perspective of how the usability can be in-house made applications versus standard applications. Also companies that not have any computer- or department for development and which are thinking of get hold of, change, replace or complement their system and applications, may have some interest in our thesis. We have used a qualitative investigation method in our study to answer our hypothesis.

This thesis aims to examine the phenomenon of gambling and consequences that may result from having a gambling problem. The thesis also intends to investigate opportunities for support and a few explanatory- and treatment models. Games are taking on new shapes and access to gambling for money is on the rise. Studies on gambling have primarily been focusing on epidemiological factors rather than factors increasing or decreasing the risk of developing gambling-related problems. The empirical material is based on eight qualitative semi-structured interviews.
