AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.

The interviews contain text, audio clip, pictures and video clip.The website contains modern programming technologies such as HTML5, ASP.NET MVC3, SQL, JavaScript and jQuery.A cover of the technologies used and how the project has been designed and implemented is explained in the dissertation. In the end of the dissertation we discuss about how the result of the project follows the goals we set up in the start phase. The result of this project is an interactive and easy to use web-site showing a part of the physical exhibition online. An easy administration to insert new information and edit existing without any major computer knowledge..

This thesis project explores technologies that enable people to experience the world through animals' senses in order to spark interest in and awareness about the marine environment and its inhabitants. The project is carried out as part of a planned ocean themed science center. The purpose is to explore how a greater understanding of the marine environment can be achieved using interactive technologies. The thesis is based on a theoretical framework consisting of academic works on experience, learning in a museum context and sensory perception. Our proposed designs are a series of, primarily, wearable devices that translate sensory experiences and principles from the marine world to humans.

The communicating home concept has been defined byidentifying the dominating communication technologiesto/from and in the homes, the most important customerbehavior and user needs, the dominating products and thedominating actors of the industry.The evaluation of the communicating home industry has beenperformed with a five forces framework analysis and theoriesregarding value migration and value structures of industries. Ithas been concluded that actors of communication technologies,goods and access services will compete fiercely. The barriersof entry will however be high. When it comes to contentservices the situation is completely different. These actors will,to the largest extent, meet lower competition and low barriersof entry.

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

Differences between groups or individuals in a society with regards to access to information and communication technologies (ICTs) are known as the digital divide. The digital divide pertains to differences in physical access to computers and the Internet as well as knowledgein using technology. Important factors affecting the digital divide are disabilities, age, gender, socioeconomical background, ethnicity and geography. The digital divide appears on several levels: internationally, nationally, regionally and locally. Individuals who, for some reason, have limited or no access to information and communication technologies risk, among other things, to experience social exclusion.

The aim of this paper is to define the perceived consumer values that physical record stores create in order to compete with other distribution technologies. A qualitative method has been used, based on interviews with managers of three records stores in Stockholm. Interviews with their customers have been conducted also. The content has been analyzed with passable theories and the two sources have been compared when adequate.The conclusion of the study is that the physical record stores create many different consumer values, and that many of these are hard to transfer to other distribution technologies. One of the most important values for the consumer is that the personnel have a broad knowledge about music.

This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.
