By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

The technology used in the development of web-applications is evolving at such rate that it has become more and more important to keep web-applications modern. If an application is based on a technical platform that is not renewed, the platform may over time develop into an obstacle in further development of the application. There may be compatibility issues and some of the code may be unnecessary due to abstraction, and therefore more time consuming to work with. Sometimes the reason may be that an application has been built to run, and is running on an application server that is no longer being maintained. The system can be large and modernization can cost a lot.

This thesis investigates how a developer can move a desktop application to the web environment. The investigation also includes finding out what are the limitations of a web application and what is not possible to move to the web from the desktop. The question is whether there is any functionality that is gained or lost in the web application after the move.A survey has been conducted to find out what types of problems occur when moving an application from desktop to the web. The authors of this thesis have developed two prototypes for a company who wants to move a limited part of their current desktop application to the web in the future. The prototypes have been developed in Silverlight and ASP.NET.The survey has revealed that one of the disadvantages of web applications is the difficulty in working with local files and hardware on the computer.

The problems caused by the current engine casing in aluminum for Volvo Buses Corp. are the mainfoundation for this degree project. Lack of maintenance combined with a construction poorlyadjusted for assembly has resulted in the fact that the engine casings rarely get reassembled whenthe service is completed.The degree project has mainly been following ?Olssons. F, Principkonstruktion, Compendium, Lund?and ?Olssons.

We where asked to write a webapplication, with similar functionalityas an existing desktop application. The application can todayrecord sounds from a person, mix it together at the optimal place withanother, similar sound and play back the result.The application used mathematical calculation that the developerswhere not familiar with, therefore it was decided to focus on the partsthat involved recording and playing sound, to pave the way for anyfuture implementation.The follwing prototypes where implemneted:1. Read a sound clip from a file.2. Splicing of two sound clips at different points in the clips.3. Generate the sound of a guitar.The result of this evaluation is that web browsers today are notready for this type of application, but that there is potetial as soonas W3C have standardised the use of a microphone as a source to theexisting DSP functions..

Millions of people are using search engines every day when they are trying to find information on the Internet. The purpose of this report is to find out how people formulate search queries. The result in this report is based on an empirical study which is based on a search log from the Swedish search engine Seek.se.One of the results in this thesis is that nearly all search queries are based on keywords..

The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.

This report details the development of an application for personal safety for the Android operating system. Android is a relatively new platform, primarily used on mobile phones.The purpose of the developed application is to give the user the possibility to easily and quickly alert a number of contacts by phone in case of emergencies, and to show the user?s location on a map. This is not only used during emergencies, but for other purposes as well ? for example to monitor a jogging round.The project was carried out in co-operation with the company D-Safety, the developer of the "SoftAlarm" ? the product on which the developed application is based..

To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming interface (API) to be used when developing volume-rendering applications. A complete application programming interface has been designed. The interface is designed so that it makes writing application programs containing volume rendering fast and easy. The interface also makes created application programs hardware independent.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

The aim of this report is to give the reader insight into the development of theweb-based accounting application SuperBooky. Accounting is a complex task thatmany beginner entrepreneurs struggle with. The development of this application wastherefore focused on making accounting as convenient and as easy as possible. Theend product targets small enterprises and its functionality was designed with this inmind.To make sure that the application was designed in a user-friendly way, polls werecarried out among individuals with basic accounting knowledge. These polls werethen used as a basis when the application was under development, to ensure that itwas well-suited to the target audience.This project was carried out as a bachelor?s thesis for Chalmers University of Technologyand University of Gothenburg during Spring 2015.

This thesis presents an application that performs positioning of modules automatically based on given data for every module, and the development of it. The basis of the application is from a previous thesis code. On top of that code, more features and error handling has been added, as well as fixes for various bugs. A stress test has been performed and further development possibilities are being presented.The thesis work was carried out at Toyota Material Handling Mjölby (TMH) and was made in parallel with another thesis by Fredrik Holden who was generating data for the application. For a complete understanding of the theory and background, please also read Holden?s thesis report ?Development of method for automated positioning of 3D-representations of a modularized product?, as well as the former thesis  ?Analysis for Automated Positioning of 3D-representation of a Modularized product??..

GIS on the Internet is a rather new phenomenon, which has evolved from the need ofdistributed geographical data. It is also a powerful tool for presenting information on theInternet. This master thesis aim to create a web based GIS application with information onlime spreading and the situation concerning acidification in the county of Kronoberg, Sweden.The web based GIS application will be used by the county administrations in Kronoberg toinform the public and the municipal authorities of current counteracting acidification activity.This report includes documentation on acidifying processes and liming activities, which arepublicised together with the web based GIS application. The web based GIS application wascreated with ArcIMS, a new program in the ESRI family of GIS programs. The programincludes a guided structure, to development of everything from a map to a complete GISapplication, including mapservice and websites.

The objective of this project was to develop an application for mobile phones using the Android operating system. The main goal was, with the help of GPS, to pinpoint locations, measure distance traveled and illustrate the progress on a map. Functionalities for just showing the map, fetching addresses and saving to a database was also implemented. The result of the work was a proper application, called MeasureApp, that fulfills the goals set in the planning stages of the project. MeasureApp can be used to measure distances where accuracy is not a main factor, i.e walks or runs.

Examensarbetet har genomförts i samarbete med innovationsföretaget ProboNova Medical Innovations AB. ProboNova jobbar främst med konceptframtagning av medicintekniska produkter. ProboNova tar sedan en Provisional Patent Application på konceptet och licenserar ut det till ett större företag. Genom att licensera ut koncepten slipper de kostnaderna för kliniska tester bland annat. Examensarbetet grundades i att ProboNova ville ha hjälp med att ta fram ett koncept på en ny sårhake. Projektet har genomsyrats av designprocessen där förstudie och idégenerering har varit de två dominerande delarna. I slutet av projektet presenterades ett koncept som uppfyllde alla krav och detta koncept togs det senare en Provisional Patent Application på. Tanken är att examensarbetet ska ge läsaren en bättre förståelse för hur man kan jobba med designprocessen och lära sig fördelarna med att välja en Provisional Patent Application istället för en Nonprovisional ansökan..
