En utvärdering av spelmotorn Unity för produktion av interaktiva GIS-applikationer

Nilsson, Johan, Åhlander, Carl January 2014 (has links)
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.

Approaches for Automated Software Installations in Windows

Ydremark, Anders January 2014 (has links)
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.

Utveckling av internordersystem för SharePoint / Internal order system development for SharePoint

Johansson, Viktor, Jeppesen, Christian January 2014 (has links)
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.

Tempus Custode : En GPS-tidrapporteringsapplikation

Fryxelius, Peter, Oscar, Ternström January 2014 (has links)
This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user’s task of time reporting his day is greatly simplified. The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver. There is a personal integrity issue inherent in this operation, because an employer may supervise an employee’s position during the work day. The application may still, with some qualifications, be in accordance with the Swedish Personal Data Act. The Tempus Custode project comprises one tentatively complete application that runs on all modern smartphones. A simple server has been implemented, together with a database. The administrator tool has not been developed. Data in the database are otherwise viewed and manipulated. The results of testing the system have been satisfactory, leading the authors to claim that the project’s objective has been fulfilled: Tempus Custode can significantly simplify the work day of the user, by offering simple, semi-automatic, GPS time reporting. / Denna uppsats beskriver Tempus Custode, en smarttelefonapplikation med vilken användaren kan registrera arbetstid och restid under arbetsdagen. Applikationen kommunicerar via en server med en databas. Datan som sparas i databasen kan manipuleras med ett administratörsverktyg, främst för att skapa färdiga tidrapporter. På så sätt kan användarens arbete med att tidrapportera sin dag avsevärt förenklas. Applikationen diskriminerar själv mellan arbetstid och restid, genom att applikationen löpande hämtar GPS-data från smarttelefonens GPS-mottagare. Det finns ett integritetsproblem i och med detta förfarande, eftersom arbetsgivaren kan följa den anställdes position under arbetsdagen. Applikationen kan ändå, under vissa förutsättningar, sägas följa personuppgiftslagen. Projektet Tempus Custode består av en mer eller mindre färdigutvecklad applikation som fungerar på alla moderna smarttelefoner. En enkel server har implementerats, tillsammans med en databas. Däremot finns inget utvecklat administratörsverktyg, utan data i databasen beskådas och manipuleras på annat sätt. Resultaten från tester av systemet har varit tillfredsställande och leder författarna att hävda, att målet för projektet har uppnåtts: Tempus Custode kan väsentligt förenkla användarens arbetsdag, genom att erbjuda enkel, semiautomatisk GPS-tidrapportering.

Measuring and Monitoring Battery Status

Owona, Ignace Flavien January 2014 (has links)
Embedded systems are the most widespread technologies today. These technologies include hardware and software. We may meet them from simple household appliances such as the washing machine and microwave oven to more sophisticated appliances such as aircraft, medical appliances, and automobiles not to mention mobile phones, TVs and radio receivers, leisure gadgets, etc. This project thesis goal is the measurement and the monitoring of the discharge of the battery used as the energy supplier in a quadrocopter. Its particularity is that the battery monitoring is done remotely through a radio link in embedded systems. To do this, the discharge of the battery will be measured by a hardware called the charge measurer which will measure how much charge flows from the battery. The status of the battery will be transmitted to the ground by a radio transmitter device and it will be received by a radio receiver module. The monitoring of the battery status will be carried out by software implemented in IAR Embedded systems. The Monitoring of the status of the battery will happen from the ground when the quadrocopter flies. When the quadrocopter flies the user will know how fast the energy is consumed and when the flight is over, the user will know how much energy was consumed. This can help the user to monitor the energy consumption and to know when it is possible to land the appliance safely. To perform this project several important tasks will be done such as:   -Conception and the design of the current measurer circuitry -Design of the printed circuit -Laboratory testing -Simulation of the electronic circuit with the help of some tools like Orcad and PSpice -Mounting of the electronic components on the printed circuit board -Design of the software -Writing the C code in the platform IAR Embedded system

Online inference of topics : Implementation of the topic model Latent Dirichlet Allocation using an online variational bayes inference algorithm to sort news articles

Wedenberg, Kim, Sjöberg, Alexander January 2014 (has links)
The client of the project has problems with complex queries and noisewhen querying their stream of five million news articles per day. Thisresults in much manual work when sorting and pruning the search result of their query. Instead of using direct text matching, the approachof the project was to use a topic model to describe articles in terms oftopics covered and to use this new information to sort the articles. An online version of the topic model Latent Dirichlet Allocationwas implemented using online variational Bayes inference to handlestreamed data. Using 100 dimensions, topics such as sports and politics emerged during training on a 1.7 million articles big simulatedstream. These topics were used to sort articles based on context. Theimplementation was found accurate enough to be useful for the client aswell as fast and stable enough to be a feasible solution to the problem.

Scaling an Optimization Engine for a Decision Support System

Sandvik, Joel Emil January 2013 (has links)
The objective of this survey has been to determine whether an existing linearprogramming model could be used to implement a system for the optimizationwith regards to the matching of transports and requests. Realdata from Härnösands harbour was enhanced and used to simulate scenariosthat would be used and applied within the system. The LINGOsolverwas integrated within a system that was developed in .Net to addressissues around data in- and output, data persistence, and stability.Performance tests revealed that the system and model performed inadequatelyon larger datasets. A simpler model was developed that handlea subset of the types of datasets handled by the first model, a subsetwhich includes the data collected from Härnösand harbour. The simplermodel was implemented with the AMPL/CPLEX-solver software, and furthertests showed that this provided a much improved performance to thesystem. These results indicate that further investigation might be requiredregarding the differences in performance between combinations of differentsolvers and models, and that a complete and production ready systemis likely to benefit from incorporation of various models that can be appliedto various characteristics of the input data.

Design Metrics on Prediction of Open Source Software Complexity

Tadesse, Milkias January 2013 (has links)
The growth of open source softwares (OSS) is playing a big role in the industry. The important contributions that have been generated over the past years are found to be useful for software developers. The development method used to produce open source software is different in that it participates programmers who are interested in coding. On the other hand, software complexity is one aspect that should be raised during the development of software. It is considered as one factor linked with different characteristics of quality in software. Since there are multiple developers located in different places who commit their codes to repositories, there is a need to understand the complexity of OSS before using them.A systematic use of object oriented design metrics can be useful in helping to solve this. In this paper, the complexity of the most popular open source softwares is investigated by the use of statistical assessment of the metrics. In order to facilitate this, it includes a case study to investigate complexity of ten popular projects that are available sourceforge.The case study has shown that applying software metrics that would measure the different aspects of software would be useful in analyzing, studying and improving the complexity of open source software.
