An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.

IT exist and are needed in larger organisations today, this creates possibilities for new applications. It has become more frequent with IT within HRM which has developed new concepts like e-HRM and HRIS which links IT and HRM together. We have through qualitative content analysis of interviews investigated how IT-tools affect HR-workmanship. The purpose is to create a basis for describing how employees experience their work with HR within a PA-system. The basis of the PA-system will then answer if it contributes or limits the employees and their activities.

CML Data AB is a small IT-company that offers complete IT-solutions adjusted to the needs of the customers. It is hard for the employees to bring all necessary papers, files and software when visiting a customer. They also have difficulties planning their daily work and to keep track of each other, because of the lack of a shared calendar.The purpose of this report is to answer the following questions:- How do you develop a centralized information system for CML Data AB where it is possible for the employees to gain access to files, plan their days and where the customers can get access to relevant information?- How do you develop an information system that is easy to manage?- How do you make it easier for the employees at CML Data AB to update their homepage?We discussed the problems and the future information system with the employees and were able to establish a set of needs and requirements which we then used as a foundation during the software development. We used user centered system design during the whole process and focused a lot on usability and interaction design.The project resulted in a stylistically pure and user friendly portal.

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.

The idea for the thesis ?Construction and implementation of a mobile prototype; The Lovebomb? originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver.

SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.

Mediation of fiction for adult users in Swedish public libraries is a subject which has been little studied from a theoretical perspective. The motivation for this thesis was based on this realization, and the opinion that actual library users too seldom get their voices heard in library and information science-research. The thesis analyzes interviews with seven library users in which they have been asked to talk about the librarys work with mediating fiction. The answers are analyzed using a discourse analytic approach to see how the librarys work with mediating fiction is constructed in the users talk.Two main discourses are identified, one authoritative and one neutral. In the authoritative discourse librarians are talked of as experts who have the knowledge to guide users to the ?right? literature.

This Master?s thesis investigates user education at high school libraries. The aim of this study is to examine user education and the educational approach that librarian?s experience in their teaching. The method used for the study is qualitative interviews with seven high school librarians.

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical User Interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

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.

IT utgör en stor del av majoriteten av folks vardagliga liv. Smartphones och surfplattor har om möjligt ytterligare ökat vår användning av tekniska enheter och prylar på en daglig basis. Arbetet tas med hem i en större grad med hjälp av laptops, VPN och molnmöjligheter. Mail kan tas emot i princip var och närsomhelst på dygnet. Men hur bra är säkerheten? På arbetsplatsen hanteras mycket av IT-säkerheten och ansvaret för den ofta av erfarna och dedikerade anställda, men hur ser det ut hemma där användaren själv har ansvaret för sin IT-säkerhet?I denna studie analyseras och identifieras risker och problem vid hantering av olika aktiviteter relaterade till IT-säkerhet i hemmet.
