Interaktiva applikationer som hanterar visualisering av geografiska informationssystem (GIS) är ett växande ämne. Denna studie har använt spelmotorn Unity som verktyg för att skapa en prototyp av sådan applikation med Högskolan i Gävles campusområde som visualiserad miljö. För att åstadkomma detta har arbete med bl.a. 3D-modellering, texturering, programmering och ljusmappning genomförts. Utifrån studiens resultat ges vissa rekommendationer kring de moment studien behandlar. Dessutom utvärderas Unity som digitalt verktyg för denna typ av produktion. Resultatet visar att i den stora bemärkelsen innehåller Unity det mesta av den funktionalitet som är önskvärd för denna typ av produktion. Programmets möjliga brister handlar primärt om att dess funktionalitet skulle kunna förbättras samt att fler förval för visualisering och förenkling av arbete med grafiska gränssnitt skulle kunna implementeras.

Today Siemens Industrial Turbomachinery AB (SIT AB) installs operator-stations manually. This is a tedious and time consuming process. In this report several different approaches is researched and presented for an automated solution. Because automated installation is not a widely researched area, an exploration of different approaches and technical difficulties has  been made to use as a base when finally arriving at a recommendation for SIT AB. The result of this report shows that an approach using the Windows Registry is the best solution for implementation of an automated solution, and that other approaches either is too time consuming or technically challenging to be feasible. This report is meant as a decision basis for SIT AB in their automation of operator-station installations.

SharePoint is a web based platform designed to provide internal communications and file sharing for businesses and organizations. In this project, we created a system consisting of multiple applications to be used together with SharePoint. These applications are meant to simplify the workflow for internal orders of products. The system is targeted towards companies that do not have a flexible approach to digital orders or companies that want to integrate this functionality into their SharePoint platform.   The project includes, in addition to the creation of the system, installation of the software and the servers needed to run a SharePoint environment and their configurations. The system consists of four applications where one of these, the store application, is required for the system to be used at all. The other applications are an order management application, a purchase application and an incoming delivery application. Of these four, we have implemented the store application and the order management application.   Our hope is that users will find the system easy to use and graphically appealing.

Robot-assisted surgery is one of many new techniques being implemented across medical institutions world-wide. Using robot assistance allows the surgeon to perform surgical procedures using remote-controlled mechanic arms. The advantages of practicing this technique during surgeries are improved accuracy, clearer visualization, better utilization of the instruments and the elimination of human errors, e.g. tremor. A technique that entails revolutionary benefits is nevertheless not adopted by many surgeons, due to lack of acceptance. The purpose of this academic study is to receive a more in-depth understanding of the relevant factors behind the reluctance of implementing robot-assisted surgical procedures. Additionally, we are interested in investigating which factor is the most significant for the overall consensus behind the new innovation. However, this study includes the hostility from the users’ perspective on this technology and how this would influence future decisions. Three separate methods of empirical evidence are used in this study and they are analyzed qualitatively. Unified Theory of Acceptance and Use of Technology (UTAUT) is chosen with the purpose of being inspired and a proposal of developing the model is submitted. This study is addressed to the scientific field consisting of researchers focusing on robots, Artificial Intelligence (AI) and the digitalization of labor. The selection of participants has been implemented in regard to the purpose of the study with a contact person from Intuitive Surgical. The results indicate how the respondents have a positive preference toward this technology. Furthermore, it is evident how the lack of sufficient investments is the main challenge for implementing this technology at additional medical institutions across Sweden. Moreover, both surgeons and surgical-nurses believe their professions will be affected by the continued influence of digitalization within the Swedish healthcare. The results from this study could be beneficial for senior leadership at medical institutions in order to further underline the advantages of the robot.

Artificial intelligence, or more commonly known as “AI”, is a growing phenomenon that gets more and more integrated in today’s technology. Since AI is starting to become a reality in the automotive industry it’s important to examine how these vehicles could be implemented both ethically and morally with the support from the general population. The current legislation in Sweden has not taken self driving vehicles in consideration, a reason for this being that AI driven cars has not yet been implemented in a large scale. Through a quantitative study the general public's acceptance and attitude towards the phenomenon has been researched. The study has also gathered data regarding who should be held accountable for accidents surrounding different scenarios with autonomous vehicles. After a statistical review of the survey the authors could conclude that if automated cars were to be implemented in Sweden to a larger extent there should also be a change within the legislation where automated cars are taken into consideration to better match the public eye. Through analysis of the study the authors concluded that a change in the current legislation concerning autonomous cars could become reality which would mean that the development process needs to be supplemented in order to assure a high level of safety.

Much of contextaware application research has dealt with the technical aspects of context capturing and how to interpret the context of a user. Little effort has been spent on the experience and usage of these systems. This thesis will present the general aspects of social awareness and present an example on how these concepts can be implemented into a location-based information system to help users navigate a potential information overload. This thesis also states that giving the users an experience of not being alone in the system increases the pleasure of using such a system. However this implies a decrease in privacy. To demonstrate these ideas I will describe a locationbased information system, GeoNotes, built by a group of researchers at SICS, the Swedish Institute of Computer Science. I will state a set of interaction requirements for how to extend the GeoNotes system with functionality for social awareness. Furthermore I will set up functional requirements for those interaction requirements to after implementation be able to conclude which interaction requirements I have been able to implement for. I will also give suggestions on how to position users in a WLAN. The deliverable from this project is a locationbased information system with functionality for social awareness. However, it was not within this project to test the system on true users. Therefore the statement that this functionality can help users to navigate a potential information overload is still just a hypothesis. To retrieve the position of a user in a W-LAN a packet is sent to all base stations in the network. In the first returning packet the mac address of contacting base station is extracted. Each base station is therefore a unique position. Triangulation was discarded due to its sensitivity to noise and weather circumstances, although a system that uses triangulation would have offered a much higher granularity.

The increasing interest in Constraint Programming (CP) we now witness gives rise to a demand for new and improved debugging techniques. Graphical tools, such as constraint- and search-tree visualizers, seem to be appropriate to get a general understanding of the complex process of constraint solving. However, many such tools have been built in an ad hoc way, forcing the developer to, for each new tool, provide relevant information from the constraint solver. In this thesis, we present a solution to the problem, limiting ourselves to Constraint Logic Programming over Finite Domains (clpfd). In order to do this, we come up with a trace structure for describing the execution of clpfd programs in detail. The trace structure consists of various trace events, each trace event containing different information depending on when in the solving process it is created. Among other things, the trace structure contains information about constraint posting, constraint awakening and domain narrowing. We also incorporate explanations in the trace structure, i.e. reasons for why certain solver actions occur. Furthermore, we come up with a format for describing the execution of the filtering algorithms of global constraints. An implementation of the trace structure in sicstus Prolog is also presented, as well as a tool using the trace; an extension to the ordinary Prolog debugger.
