One of our reasons is that we think the subject usability is interesting, is that we think it is an important. Usability is maybe the most important element when you develop or choose a system because it can save money for the companies and give the users a more delightful and better work environment. The aim of the investigation is to find out if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. The objective of our investigation is to show if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. In our case we will try to see if Karlshamns AB:s recently implemented web portal is more useful than their previous application (Movex with interacting programs) One thought with the report is to give the system developers a perspective of how the usability can be in-house made applications versus standard applications. Also companies that not have any computer- or department for development and which are thinking of get hold of, change, replace or complement their system and applications, may have some interest in our thesis. We have used a qualitative investigation method in our study to answer our hypothesis.

 Purpose/Aim: The goal of this thesis is to examine access and knowledge computers and the Internet among the senior-year students of Anacostia High School. Do the students of this facility have the same opportunity as the residents from better socioeconomical backgrounds or are they being excluded from the technology? Material/Method: To approach the thesis goal I have used a quantitative method. More specifically, a questionnaire was handed out to the senior year students at Anacostia High School. Main results: The study has shown that most of the students of Anacostia had in some way access to computers and Internet.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

The aim of the study is to examine what upper secondary school students think that they themselves and their school can do to create a peaceful society. The study combine qualitative and quantitative methods based on questionnaires distributed among 328 students in three high schools in Sweden. The survey is a combination of multiple choice and open questions. For the analysis of quantitative responses the computer program SPSS was used producing frequency tables and response rate schemes. To analyze the questionnaire's qualitative part a narrative analysis method was used.

The purpose of this study was to examine how teachers practice Arne Tragetons theory of using computers as the first writing instrument in reading and writing development. We wanted to clarify how the work from using Tragetons theory was applied while investigating if and how other methods of reading and writing instruction were used. Our interest lays in how the teachers accomplished the knowledge of this theory and also how the choice of this approach came about. To investigate this we used interviews with a qualitative nature, where seven active teachers were interviewed. They worked in three different schools in years one to three, they were all women and had various long experiences of work on the computer writing tools.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

Chefen för amerikanska marinkåren beslutade 2005 att påbörja utvecklingen av konceptet DistributedOperations (DO). Syftet med konceptet är bland annat att möta utmaningarna inom upprorskrigföring och?Small Wars? som kännetecknas av asymmetriska förhållanden mellan parterna. Grundidén medDistributed Operations är att skapa en fördel över motståndaren genom att uppträda utspritt ellerkraftsamlat och hela tiden kunna avge understöd till den ?lägsta enheten?.

Sveriges barnbibliotek tappar besökare. Allt runt omkring oss förändras, men barnbiblioteken ser likadana ut. Vi vill i detta examensarbete ändra hur barn och ungdomar ser på biblioteket, så att de känner sig mer hemma i biblioteksmiljön och som följd av detta möjligtvis ökar barnens läslust. I stort vill vi göra biblioteket mer attraktivt och tilltalande för barnen. Vi har i tidigare projekt uppmärksammat att många barn och unga har intresse för teknik och detta valde vi att dra nytta av i Bokdjungeln.

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems. In this paper focus is applied to the development process within developing applications for Enterprice Digital Assistants (EDA) and to what extent the end-users are involved in the process. Fazer Bageri AB has been choosen to represent a business corporation that uses handheld computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

Augmented reality is a technology thatcombines the perception and interaction ofvirtual objects with the real world. Itcan allow a user to visually see computergenerated models and informationinteracting with the real world through ahand held device such as a tabletcomputer. This opens up a range ofpossibilities, especially in theconstruction sector. A construction siteis permanently changing and the need forprecise and updated information iscrucial. The ability to enhance the realworld with virtual objects and informationmay make many plans printed on paperabsolete.This report describes how workers in theconstruction sector would benefit fromusing augmented reality on a tablet innumerous situations and the technologyneeded to achieve AR on a tablet.

AI är något som blir allt viktigare inom dagens spel och får allt högre krav på att agera mänskligt och intelligent. Detta kandidatarbete undersöker vilken metod som är att föredra för att skapa en AI som kan lära sig av sina tidigare erfarenheter. Några av de metoder som undersöks är trädstrukturer, Artificial Neural Network och GoCap. Genom att skapa en applikation med en av metoderna samt göra en undersökning på hur AI:n i applikationen upplevdes fick vi resultat om denna metod var användbar. Utifrån detta diskuteras det ifall andra metoder hade varit mer effektiva, hur man hade kunnat förbättra AI:n samt hur framtiden för spel-AI skulle kunna se ut..

The aim of this study is to analyze and describe the research front within information science. To reach this purpose we ask the following research question: Which research themes can be identified within the subject field of information science by using bibliographic coupling in combination with cluster analysis.The data for our study consists of articles from the journals Journal of the American Society for Information Science and Technology and Journal of Documentation throughout the years 2004-2006. The bibliographic information from the articles was analyzed with the combined methods of bibliographic coupling and cluster analysis. This gave fifteen clusters within which we identified research themes. When analyzing these results we found four main fields of research within the research front of information science: Information retrieval, bibliometrics, knowledge organization and information science as research discipline.

In today?s society, it becomes more common with tablets, that makes us interact with computers in a whole new way. For example these are used to read and write e-mails, surf the web and playing games. Another manner of use of these tablets is to read and edit PDF documents. PDF handling is often meant to be used in books and inregular text documents, but it could also be used in the management of drawings.An industry that would benefit greatly from the use of tablets for this purpose is the con- struction industry.
