FÄ handlare har tagit initiativ till implementeringen av mobilbetalning, trots att handeln spelar en avgörande roll i utvecklingen. Syftet med denna uppsats Àr att undersöka vad som driver implementeringen av mobilbetalning inom handeln. För att uppnÄ syftet gjordes en fallstudie bestÄende av intervjuer med handlare som implementerat den mobila betaltjÀnsten SEQR samt en insamling av bransch- och samhÀllsorienterad information. Resultatet visade att de starkaste drivkrafterna för implementeringen av mobilbetalning Àr minskade kostnader, liten finansiell risk, optimistisk framtidstro samt en önskan om ett alternativt elektroniskt betalmedel. Dessutom fungerade ytterligare faktorer som drivkrafter, exempelvis förbÀttrad image, beroende pÄ företagets typ av verksamhet och tekniska profil.

The options are geothermal, district and pellet heating systems.

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment.

The purpose of this study is to increase knowledge and clarify how active educators regard ICT- tools as aids, both the educators currently using the ICT- tools to improve writing skills and educators who have not yet embraced it. The study is based on four interviews with educators working within the age groups grade 1- 3. The findings of this study show a strong commitment among all educators, in terms of students' writing skills and their different approaches to working with writing skills, which is important as one method should not preclude another. In the findings a considerable curiosity can be seen for ICT- tools for writing instruction by the educators who have not embraced it. The interest and commitment of the educators who have embraced ICT- tools in their teaching is great..

How should a fair income tax system be designed? Since Estonia became the first country to introduce a flat tax on incomes in 1994, this question has been in focus of public debate. The aim of is this thesis is to show that a flat income tax system, combining a proportional tax rate on all incomes with an allowance exempt from tax, is consistent with the demands of justice. In order to achieve this I construct a two level argument using normative method. The first part consists in the justification of a specific ethical theory which is derived from to notion of human dignity.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

An information system is something that evolves over time to enhance the company that is using it. The technology for building an information system is also evolving. New methods and new programming languages make system development easier. As new technology breaks ground and the demands of a company?s information system grow, the company will sooner or later get to a point where a change in the base of the system is necessary.

Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.

This analysis recommends not to use Windows Server 2008 without properevaluation in any system containing classified information. The reasons are too lowassurance and too weak authentication. If Windows Server 2008 is to be used itshould be supplemented with a stronger authentication mechanism. The installationshould preferably be of Server Core type and the server should be maximallyhardened..

Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.

Purpose/Aim : The aim of this study is to investigate and describe "kontaktmannaskapet" in the Swedish correctional system. I also aim to investigate if there are any differences between how the different actors involved in the correctional system look at this phenomena and how different sociological theories can be applied on "kontaktmannaskapet" in order to make it more comprehensible for the actors involved.Material/Method : This investigation is based on a larger qualitative inquiry consisting of several personal interviews. Further material has been used, such as literature and reports about "kontaktmannaskapet" inside and outside the correctional system.Main results : The overall opinion about the "kontaktmannaskapet" is positive. "Kontaktmannaskapet" as a working method of the correctional officer has a potential to become a useful instrument in rebuilding the lost identy of the inmate as well as reducing the stereotypes often associated with the relationship between inmates and prison personnel..
