The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality Simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

Vehicle Simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice Simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle Simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.

Trådning är svårt att få så effektivt som möjligt och det är komplicerat att skriva kod för det. Det här examensarbetet beskriver en implementation och jämför sedan implementationerna. Utvärderingen av implementationerna i Java, Jetlang och Erlang avslöjar att Jetlang skalar bäst både när det gäller komplexitet och hårdvara. Erlang behöver minst extra kod för att hantera trådning. När det gäller många små körningar har även Erlang bäst prestanda men tappar försprånget snabbt när komplexiteten ökar..

I denna rapport presenteras hur en Simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga Simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Denna underso?kande designstudie utforskar hur visuellt material till en Simulator kan komma att se ut och hur va?gen fram till det fa?rdiga designen kan se ut. Simulatorn som sta?r i centrum fo?r just denna studie kallas fo?r Simulerade Provokationer (SimProv) och har la?rarstudenter som huvudsaklig ma?lgrupp. I SimProv kan la?rarstudenten som anva?ndare va?lja mellan fyra olika handlingar i en klassrumssituation.

This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car Simulator was first built. Both the car Simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.

En Simulator ger inte bara möjligheten att efterlikna verkligheten, den kan också förbättra och förstärka viktig information för den som tränar. Inom medicinsk Simulatorutveckling är strävan efter att efterlikna verkligheten till fullo mycket stark och de möjligheter tekniken ger har i stort förbisetts. I denna studie lades fokus på de två förbisedda områdena pedagogisk förstärkning och spatial kognition. I en experimentell studie undersöktes effekter av införandet av ett visuellt pedagogiskt verktyg (förstärkande hjälplinjer) under träning i en vr-Simulator för ortopedisk kirurgi. De erhållna resultaten sattes också i relation till deltagarnas spatiala förmåga.24 läkarstudenter genomgick en timmes introduktion och träning följt av eftertest både direkt efter träning och en respektive två veckor efter träning.

In order to facilitate testing of anesthesia machines a patient Simulator has been required by Maquet Critical Care AB. A patient Simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient Simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient Simulator has fulfilled the requirements.

A key part in the development and verification of digital systems is simulation. But hardware Simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster Simulators handling millions of gates are needed. We investigate how to create a software gate-level Simulator able to simulate a high number of gates fast.

This paper describes the design and implementation of an automated build system for the JAS39A Simulator FUS39A at HiQ:s offices in Arboga. The assignment was to automate the process in which modules are built; the Simulator is composed of a number of modules which are built manually at the end of each week, this process takes about a day of manual labor. The system can automatically build a module as either a scheduled service or by manual invocation. The system contains functionality for reporting the build results to any given recipient by e-mail. The purpose of the system is to free up the time put into manually building the modules for better suited tasks by automating the build of FUS39A.The assignment was split into two parts, an analysis part where information of the old system was gathered, tools and methods were chosen and the new system was designed.

I många nätverk antas det att någon form av fix infrastruktur existerar och att nätverkets olika noder kan använda denna för att kommunicera med varandra. I ett ad hoc-nätverk antar man att det inte finns någon fix infrastruktur och att noderna måste använda varandra för att kunna kommunicera. Ett exempel på ett ad hoc-nätverk kan vara bärbara datorer sammankopplade med infraröda länkar under ett möte. När ad hoc-nätverket är mobilt innebär det att noderna rör sig.I detta arbete har de tre protokollen Epidemic, GeoMean och GeoMove tillsammans med de två rörelsemodellerna Waypoint och den utökade slumpmässiga vandringen implementerats i en nyskriven Simulator för denna typ av nätverk.De två Geo-protokollen är nyutvecklade och syftar till att använda geografisk information för att underlätta kommunikationen i denna kategori av nätverk tillsammans med den nya utvidgade slumpmässiga vandringsmodellen..
