The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.

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.

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

Kunskapen om TV- och datorspelmissbruk bland ungdomar är idag väldigt begränsad. Stillasittande/fysisk inaktivitet, som TV- och datorspel ofta innebär och som kan innebära negativa konsekvenser, blir allt vanligare. En semistrukturerad intervjustudie har genomförts på sju män i åldersgruppen 17-29 år i syfte att undersöka drivkrafterna bakom mäns spelbeteende i tonåren. Dessutom har information om spelmissbruk bland ungdomar inhämtats av fyra yrkesverksamma inom spelområdet. Detta samt kopplingar mellan TV- och datorspel och spel om pengar har gjorts p g a bristen på forskning om TV- och datorspel.

AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

This Bachelor Thesis in the area of Computer Science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool. Advan-tages and disadvantages of this way of working are discussed. Our studies show that distance work is a good complement for personal meet-ings between designer and co-developer.

How can we use modern X-ray technology to raise awareness of the information that is hidden in historic upholstery? The materials and techniques add information to the history object in question and  about a profession that is sparsely documented in our country. The knowledge we have today has largely been obtained by studying damaged upholstery, or by removing the show cover and upholstery, a technique which involves high risk of damaging the upholstery. X-ray technology offers  a non- intrusive way to examine historical upholstery.Through case studies, I examined four artefacts. The artefacts went trough an inititial visual exam before being transported to The National Heritage Board in Visby where they underwent a thorough X-ray exam.

This thesis describes the introduction of Web 2.0 education into Swedish LIS education with emphasis on the driving forces and obstacles in the process. It also discusses the possibilities of estimating the appropriate time for the start of new educational courses introducing new technologies, when it is uncertain if the technologies in question will sustain for a long enough period of time to make the educational effort worthwhile. The data on the Web 2.0 education was collected during the spring of 2010 from the Web pages of the five LIS departments in Sweden, namely Borås, Lund, Umeå, Uppsala and Växjö, as well as by 10 interviews during November and December 2010 with two representatives from each LIS department..The key finding is that Web 2.0 is covered in Swedish LIS education and embracing both practical and theoretical issues. The main driving forces have been both the needs of the profession and an academic research interest. It is concluded that Rogers??S-curves? as described in ?Diffusion of Innovation? can be used as a tool in order to improve the understanding of when to introduce education in new technologies.

Now a day?s there is dramatic change from traditional to digital information processing in construction industry. This change can be visualized in the project concept stage where it now has accessibility to join all the data in one place. Location-based planning technique simplifies scheduling by visualizing the schedule efficiently and has many advantages such as might shortened the project period by about 10 - 20 % if the company uses location-based technology, reducing risks in many ways by maintaining production continuity and identify collisions between things etc. Vico Office software has been used for Location based planning technique and in this thesis.The purpose of this thesis work was to demonstrate how location -based planning technology change the scheduling stage in Peab, potentially reducing the project time.

The purpose of this Master?s Thesis is to examine and describe how a wiki can be used in the information seeking education. We believe that the preconditions for education and learning are changing; technology and Internet has introduced new tools for the learning situation. To examine this we will describe how the wiki technology can be used in the information seeking education, describe how the goals of the information seeking education are reached when using a wiki and lastly investigate the school librarian?s pedagogical role in wiki-based education.

To challenge the competition within the construction business there are requirements ineffectiveness and use of operating computer based programs and work-methods. Thecomputer based programs are continuously improved and can at some point be the start of anew work-method. The work-method of tomorrow can be Building Information Modeling(BIM).This Master of Science Thesis gives an understanding in what BIM is and what therequirements for Sweco Theorells are in a future BIM-use as a consulting-firm. Theunderstanding is presented through a study of theory within the subject. The way of thinkingand acting among different disciplines and individuals within the building process isexplained through an interview study.The term BIM is regularly used.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation. The possibility to protect oneself against attacks from the outside becomes increasingly difficult.
