This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system..

In today?s modern society with high-speed connections covering the globe people are more than ever finding themselves gazing into the cold lights of the computer screen. On the other side a strange and exciting world yet to be explored awaits. Many are those who spend hour after hour running over green hills swimming in vast blue oceans in the lands of Azeroth, the playfield in the MMORPG game World of Warcraft. In media we often read and hear alarming reports on players stuck in this virtual world, ceasing to play a part in the real world.

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

This essay is about the principles and rules that control persuasive computer games. The term persuasive games mean computer games, video games and other similar artifacts that are produced to shape opinion. The rhetorical scholar Ian Bogost at Georgia Tech claims that this kind of games mainly get their persuasive power by using procedural rhetoric and that games as a medium gives special conditions for procedurality.  By procedural rhetoric Bogost means an argumentation that is based on rules and choices, as opposed to texts, movies and images. (Bogost 2007). Bogost describes these procedures as quite specific for games and claims that they differ qualitatively from ?ordinary? rhetorical arguments even if they just as other arguments work by establishing enthymems.

Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.

The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

The aim of my study is to investigate if and in that case how the writing process and texts written by students in the upper secondary school are affected by the writing tool; does it matter if they write their texts on a computer or by longhand? Another objective is to compare such an effect with the findings of previous studies performed on earlier generations of writers. The first part of my study was a survey. It showed that two thirds of the 67 students participating thought that they would have written better texts in the national writing test if they had been able to use computers. In the second part of the study each of the fourteen participants wrote one text on computer and another by hand.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Pipe replacements with bathroom renovations are complex construction projectshighly dependent on the construction work carried out in the residents? homes whilethe residents still live there. This fact makes the flow of information from contractorsto the residents of an important success factor. In the current situation thecontractor, Aros Bygg & Förvaltning AB, notifies the residents? information throughpaper notification, which gives managing the work involves a lot of paper work.This thesis examines whether and to what extent the contractor may replace thepaper notification with a web-based information channel.

Idag väljer många företag och kommuner att placera data i molnet istället för på en lokal server, detta medför nya problem som tidigare inte varit aktuella. Datainspektionen har påpekat brister i hur två kommuner använder molntjänster för att lagra personlig data då de ställer sig tveksamma till molnleverantörernas hantering av data samt insynen till molnleverantörerena. I detta arbete kommer det undersökas hur den svenska personuppgiftslagen fungerar när data läggs ut i en molntjänst. Resultatet av uppsatsen kommer även visa på de olika säkerhetshoten som finns i molnet och se vad säkerhetsexperter säger för att ta reda på om kommuner och företag är medvetna om och uppmärksammar samma hot. För att ta reda på detta har intervjuer genomförts med en svensk molnleverantör, företag som utvecklar tjänster mot molnet, privatpersoner som nyttjar molnet och experter inom säkerhet från Blekinge Tekniska Högskola, BTH. Resultatet av studien visar att det är svårt att se om en amerikansk leverantör uppfyller de svenska lagarna för personuppgifter, det visar också att det är teoretiskt möjligt att anlita en svensk leverantör och uppfylla lagen. Det har även visat sig att den största oron gällande molnet är bristen på kontroll av data..
