In relation to the development of IT-products it is very important that the software supplier is aware not only of the target group but also the field of application. Usability should characterize the whole IT-design process as, in relation to this context, design includes more than merely those aspects which are visible to and thus can be interpreted by the naked eye. The study examines the specific qualities and properties that substantiate the usability and the demands that a customer rightfully expects from an IT-product. The user and the customer are highlighted in the same context in order to demonstrate that it is through the customer that an IT-product is defined as being useful. Thus, from this perspective, the user and customer can be considered as being the same person.

This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.

Digital games are today avaliable on all kinds of different platform. Games and game thinking is also increasingly being applied within non-traditional contexts. This thesis explores the term "gamifiation" which can be defined as "the use of game design elements in non-game contexts". The purpose of the study was to identify and give perspective on the discourse surrounding the use and applicability of the term today. More specifically, it explores the possibilities of the potentially value creating ability in the context of work, and focused on the application of gamified software in the context of project work.

This study concerns design thinking and how to achieve usability when designing applicationsfor smart watches. The study's focus is on interaction and design for online auctionapplications such as Ebay and Tradera. After studying usability and design for devices withsmall screens, guidelines and design principles for interactive systems, we developed apaperprototype for an auction application.

After collecting the data we analyzed the responses andfeedback on our prototype and combined the results to previous studies.

This thesis lays the foundation of the future routines of effective error repotring fortraffic devices in the raiway sector.If a device, for example a timetable display, stops working it is vital that the device isfixed as fast as possible so that the travelers dont miss any important information.The methods that are used today are old and not very effective. It can take time forthe repairmen to find the right device or locating the broken component. At the sametime he is supposed to maintain telephone contact with central control throughoutthe whole session.The need for a new, more effective, system is vital to make the whole repair pfocessmore effective and let the repairmen work without having to contact the centralcontrol by phone.I started this work by examining the possibilities of assigning every object with aunique identifier (ID tag) that could be accessed by a manual scan device. The ideawas that the ID tag could holw information about the object and be obtained byscanning the ID and get the information presented on a mobile device.The work also included building a internet application that enabled the reader to seeand change the information on the ID tag.The result was a database that stored information of different objects which could beobtained by scanning the ID tag and presented by a internet application..

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.

The aim of this thesis was to investigate the accessibility and activities for dyslectic adults in public libraries in the Swedish county of Södermanland. The questions that were to be answered were four; to what extent do the libraries provide book material and special computer software? To what extent do activities occur? Does the library staff have awareness and knowledge of dyslexia and of activities for dyslectics? What are the obstacles for good service for dyslectic library users? Two methods were used. As a first step, a questionnaire was sent to thirty public libraries. The questionnaire elicited a low level of response, but gave in spite of this an overview of the situation for dyslectics in the libraries of the county.

The aim of this study was to investigate the individual meaning of experiences of migration and day-to day life experiences before and after migration, of women that had migrated from the Middle-east area to Sweden. This was to be done with a psychological health perspective looking for stressors and salutogenic factors. A phenomenological approach was used. Eleven women where interviewed with three open questions on a trajectory theme. The analysis was supported by software Sphinx Lexica and software MCA-Minerva.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

The aim of this thesis is to establish a ?förvaltningsplans? template to Fastighetskontoret in Vasteras city. Further general information about the mission was given at our first meeting with Rolf Haraldsson, who happened to be our mentor and works at Fastighetskontoret in Vasteras city.We agreed that using the software Excel was the most appropriate way to establish the template, because Fastighetskontoret also make use of Excel in their internal system, and also because Excel has a more friendly user interface and it is more easier to use compared to other software that have complex templates.One of the first things we did was to get in contact with different fastighetskontors around Sweden so that we could either take part of their ?förvaltningsplaner? or get referred to other material that could have been used. But this turned out to be an unsuccessful strategy.

The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.
