In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

The aim of this study was to describe and analyse the perceptions that ten 12-15 yearold pupils with special educational need, who had been assigned a personal computer, have about Information and Communication Technology (ICT) in the learning process. Data was collected by personal interviews and observations. Sociocultural perspective and phenomenographic research approach were used as theoretical and methodological frameworks in analyzing and understanding the result. The major conclusions were that most respondents perceived the computer as beneficial assistive technology for learning, but some felt singled out by having a computer to assist in learning. Students had various opportunities to succeed in using their tool depending on e.g.

The objective with this essay is to establish the benefits of inserting media as an obligatory topic in the upper secondary school. In order to succeed with this I will not only type this essay I will also produce a medial production in the form of a film.  I have interviewed two senior masters on Södertörns College where I have reviewed different questions that relate to the matter's weight in school values and the society. In the study I will also reflect over existing research within the area and to link these to the issue and those interviewed opinions. In the film I also present statistics within the communication technology's increase and an explanation how one obligatory topic becomes an obligatory topic..

This essay is a study of the market strategies and situations in the telephone business. Our problem was to examine the telecom companies´ strategies to stay competitive and cope with the new VoIP technology. We chose to do a qualitative study and four telephone interviews were made with Swedish and Dutch companies. We investigated three different categories of companies in the market; industry leaders, cable companies and broadband companies to get a broad view of the market. The theory chapter is based on different strategies that companies have to or can apply to get ahead, stay or survive in a hypercompetition.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

New innovation and technology have influenced the development of product development processes and the four largest banks in Sweden have more or less been forced to adapt their products and services along new customer requirements. It may therefore be considered appropriate to involve customers in this process. This by collecting customer information and allow customers to influence the process to a greater extent. The payment solutions of Sweden?s largest banks' continue to evolve and to pay with electronic money has come to change banks' product development processes of payment solutions.

The art of producing films have been around for more than a century and the technology just continues to evolve. But although much has happened in 100 years, there are also processes, theories and practices that look the same now as then. I write this thesis because I want to find the differences between the analogue and the digital way of production. This study is based on a qualitative approach because my ambition is to seek the views concerning film production processes. The advantages of analogue film is that it contains more information than the digital formats and that it has a more cinematic style.

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

System Andersson AB is a company located in Jönköping that works with developing computer systems for the mechanical engineering industry. As of today, when this report is written, the company is working on the development of a new Manufacturing Planning and Control (MPC) system. This new system aims to create not only a user friendly interface but also a modern, stylish interface. To achieve this, the company has decided to work with a, for them, new application framework; Windows Presentation Foundation (WPF).System Andersson is well known for developing systems for different kinds of touch screens, this project is no exception. For this new user interface the company wishes to implement different types of Drag&Drop functionality.

This master thesis investigates the user education. Christine Bruce has presented a theory of information literacy in her research which has resulted in seven different aspects of information literacy. In this study I wanted to investigate what aspects there were and what they looked like in a practical educational situation. The methods used for this study were observation and a questionnaire. I analysed the observations by using Bruces aspects of information literacy to group the observed activities into the different aspects.

In this paper we have examined why seniors do not use e-business to the same extent as other age groups. Seniors belong to the age group that, according to statistics from Statistics Sweden (SCB) in 2011, utilizes e-business the least in relation to the number who use the internet. To understand how seniors reason and perceive the possibility to shop on the internet, we have conducted four interviews with people from 65 years and older. We have let the respondents answer questions regarding utility aspects, e-business interfaces, general shopping habits, risks, and whether or not they usually shop online. We also found out how seniors reason when they sell products and services.

The aim of this study is to examine the investment decision process for investments that arise due to strategic changes and are of strategic importance to the company. At the foundation of this study is the previous research in this area, done by King (1975) and Bower (1970), which examines the investment process on a more generic level. At the core is the investment decision process pertaining to Projekt X, an investment performed by NordiCorp. Having conducted a case study including six interviews with employees from various parts of the organization, combined with a large number of internal documents, the process regarding the investment decision was carefully illuminated. The results show that in many regards, this process follows the more generic investment process.

The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible.

To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.
