This thesis is   focused on identifying and documenting all   electrical equipment, such as Devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which Devices / elements   are programmed. For further notification, I am not   responsible for the programming of the Devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical Devices as, flow meters, temperature   sensors, frequency converter and   more.

In the field of IT-forensics you may often get to analyze different types of digital Devices. One ofthese Devices is the GPS navigation system. Nowadays GPS technology is getting more and morepopular and is included more frequently in different types of Devices. With this article we want topresent the differenent obstacles and possibilites that a forensic investigator is presented with in thistype of investigation. We will be comparing different software suites and make use of forensic toolssuch as EnCase.The reader should get some understanding of the methods there are for analyzing one of these Devicesand what problems that may occur in the investigation process.The article presents how the investigator can use different methods to gain information such as recentroutes, favourite destinations and other information that may be stored on the device.

Mobile Devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile Devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews.Answers given by the interviews were then used as a basis to survey the usage of mobile Devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication.

The use of mobile Devices has increased dramatically in recent years and the development of newtechnologies has made it difficult for developers to know what screen size and device the visitor isusing. This has resulted in the fact that today there is a problem with the interface for web pages onmobile Devices. They are not adapted to the flexibility required for the interfaces to be recognizedon various mobile Devices. Instead of developing two separate web pages, where one is designed formobile Devices and one for desktop and keep them both continously updated, responsive webdesign simplifies the work process. Responsive web design is a flexible and dynamic interface thatadapts to mobile device and screen sizes.

The last couple of years the use of mobile Devices such as mobile phones and PDAs has increased tremendously. Most of the these Devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.

To be able to feel a sense of belonging, people need to have the possibility to take part of the information from the society. Hearing-impaired don?t have the same possibility as hearing people when they want to take part of the information, therefore they don?t get the same benefit. This contributes to a feeling of not belonging and a sense of limitation in different social occasions. Therefore the society needs to be accessible to everyone regardless disability.

Today?s society is very focused around technology and something that is very popular is the usage of mobile Devices such as Smartphones or Tablet computers. One of the reasons why these Devices are so popular, is because of the large amounts of services or ?apps? that they can provide for the user. They can do a lot of things that makes everyday living easier for the users.The focus of this study is to find out what kinds of mobile services the users of these Devices are expecting and/or wishes to see in the future and what is required to be able to develop and use these services in a good way.We started of the study by searching for earlier studies on the same or similar subjects.

The purpose of this study was to investigate the reason behind thedecision by a company regarding the desire to use mobile access to theirERP-system and to discover whether this will involve any loss offunctionally in comparison to using the ERP-system on a computer atthe office. In addition, the pros and cons involved in using mobileDevices for accessing the ERP-system will also be examined. Semistructured telephone interviews were conducted with companies whicheither used or did not use mobile Devices in relation to their work. Atelephone interview was also conducted with a consultant who isworking with the implementation of ERP-systems and mobile solutions.The survey showed that companies with staff working in the field assellers, service personnel and construction workers want to gain directaccess to their ERP-system so as to be able to act directly and takedecisions, to have the ability to provide more efficient order processingand to send out invoices more quickly. Those companies which have notopted to use mobile Devices at work within this field are those whichare unsure of the connection to the Internet and the capacities availablewithin cellphones.

Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion Devices interconnected to the Internet by the year 2020. Before that, the Devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These Devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

Children?s use of mobile Devices is constantly increasing and has become very popular withchildren as young as toddlers. Schools in Sweden have made large investments to expand theuse of information technology (IT), and the use of mobile Devices in preschools is already acommon support tool for learning. Children?s use of IT is a relatively new phenomenon,which means that is it also a relatively new area of research.

The purpose of this thesis is to develop an application for mobile phones that simplifies communication. The company Doberman wanted to look at possibilities to develop such an application that uses Bluetooth? technol-ogy to communicate in ad-hoc networks. The aim has been an application to run on mobile phones in which you can send messages and files to other Devices and also add a user profile with personal information to share with others. The communication will take place in temporary networks created when Bluetooth enabled Devices is in range of each other.The market for mobile phones has grown rapidly over the past years and is still growing.

This report is the result of a master thesis carried out by the author, student at the Royal Instituteof Technology(KTH). The task was performed as a product development process at a companycalled Ameibo AB, located in Stockholm. It is the final task of the studies at the Master'sprogramme Design and Product Realization. The report is structured in a chronological order anddescribes the methods used, the implementation of these methods and a presentation of theresults given from these studies.Ameibo is a company located in Stockholm, distributing films on the internet. The aim of thismaster thesis was to investigate the possibilities of entering the market for portable Devices.

Portable IT Devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these Devices are for use by elderly people. This study focuses on the cognitive aspects of the Devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.
