<p>System-on-Chip is increasingly built using ASIP(Application  Specific Instruction set Processor) due to the flexibility and efficiency obtained from ASIPs. NoGAP (Novel Generator of Accelerator and Processor framework) is an innovative approach for  ASIP design, which provides the advantage of both ADL (Architecture  Description Language) and HDL (Hardware Description Language) to the  designer.</p><p>For the processors designed using NoGAP, software tools need to be automatically generated, to aid the  designer in programming and verifying the processor. As part of the master thesis work, we have developed two generators namely Assembler generator and Cycle-Accurate Simulator generator for NoGAP using C++. The Assembler generator automatically generates an assembler, which is used to convert the assembly code written by a programmer into relocatable binary code. The Cycle-Accurate Simulator generator automatically generates a cycle-accurate simulator to model the behavior of the designed processor. Both these generators are static, and can be used to generate the tools for any processor created using NoGAP.</p><p>In this report, we have detailed the concepts behind the generators,and the implementation details of the generators. We have listed the results obtained from running assembler and cycle-accurate simulator on a test processor created using NoGAP.</p> / NoGAP

<p>In this essay results are developed on two different levels. First, it is shown in demonstration that a phenomenological analysis on the lines of Roman’s Ingarden’s study of works in literature can be applied to Virtual Reality works, such as professional-simulators and video-games. In particular it can then be pointed out that: i) sound is separable from the scene, but using sound VR becomes enriched; ii) the main role in literature is left for the imagination, while in VR we find richness in concretization.</p><p>Second, it is argued in discussion that works in VR can be qualified as works of art. These electronic works may have all the aesthetical qualities (based on the phenomenology of Roman Ingarden) of the works of art in the traditional sense. So, that paper has two objectives: an analysis of VR and the search for the status of VR in art.</p>

<p>The research in wireless communications and in-vehicle computing systems has opened up new fields of applications for transportation systems. Vehicular ad hoc networks (VANETs) emerge as a contribution to the solution of providing safer and more efficient roads and to increase passenger safety. This thesis treats different issues that influence the performance of wireless vehicle communication systems and it proposes a general design procedure for the construction of a test environment for VANETs.</p><p>A comprehensive survey of the different parameters that affect the system performance in the field of wireless vehicle communications is provided. These parameters are then analysed and quantified to serve as guidelines when identifying and designing the different components of the test environment. One such component is a simulator that enables VANET performance evaluation and allows identification of bottlenecks in the network functionality. In addition, suggestions for a hardware platform and an operating system for the development of a suitable on-board test-bed for performance measurements are presented.</p><p>The design procedure of such a test environment is intended to be used by researchers and engineers working in the field of wireless communications and ad hoc networking with special regard to the automotive sector.</p>

<p>Detta är ett uppsats på D-nivå. I en tidigare kurs, inom vårat program Data- och Systemvetenskap, kom vi på en idé om hur man kan förbättra/komplettera utbildningen av nyanställda som befinner sig i en stressig arbetsplats på företag där det är ett ständigt behov av återanställning av personal. Vi utvecklade detta koncept och kom med idén till en simulator som kan utbilda personal samt minska stress hos nyanställda. Idén mognade till en Serious Game simulator baserad på en Wii-kontrollerad PC-baserad simulator med Bluetooth-stöd.Syftet med denna uppsats är att skapa en guide om grunderna i en simulator som utnyttjar Wii-kontroller som externa inmatningsenheter. I denna guide kommer vi att täcka hur Nintendos Wii-kontroll fungerar, hur man kan skapa enkla 3D-modeller i Blender och även hur detta kan implementeras i Microsoft XNA. Med denna guide som bas kommer vi också att visa hur vi utvecklat en prototyp med hjälp av ett designkoncept som utvecklats av våra kollegor Christopher Saarinen & Evin Antoniadis forskning. Detta examensarbete har resulterat i både en guide och en fungerande prototyp som implementerar de grundläggande delarna av våra kollegors designkoncept.</p> / <p>This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support. The aim of this thesis is to create a developer’s guide on the basis of a simulator with the use of Wii remotes as external input devices. In this guide we will cover how the Nintendo Wii Remote works, how to create simple 3D-models in Blender and also how this can be implemented in Microsoft XNA. With this guide as a base we will also show how we developed a prototype using a design concept developed through the research of our coworkers Christopher Saarinen & Evin Antoniadis.

Today’s automobile cockpit is filled with different buttons and screen-based displays giving input and relaying information in a complex human-machine system. Following in the footsteps of the early 1970s flight industry, this thesis work focused on creating a complete glass cockpit concept in the automobile. Our automobile glass cockpit consists of three displays. A touch screen based centre console with an interface that we took part in creating during the spring of 2006. Parallel to this ongoing master thesis, a head-up display was installed by a group of students and we had the opportunity of giving input regarding the design of the graphical interface. The third display, a LCD, replaces the main instruments displaying speed, RPM, fuel level, engine temperature etc. Together with ideas on an extended allocation of functions to the area on and around the steering wheel, creating a dynamic mode based interface replacing today’s static main instruments was the focus of this project. After conducting a thorough theoretical study, a large number of ideas were put to the test and incorporated in concept sketches. Paper sketches ranging from detailed features to all-embracing concepts combined with interviews and brainstorming sessions converged into a number of computer sketches made in an image processing software.

Simulation is an important tool when training is hazardous, time consuming, or expensive. Simulation can also be used to enhance reality by adding features normally not available in the real world. The aim with this work has been to develop and evaluate methods that could improve learning in oral radiology utilising a radiation-free simulator environment. Virtual reality software for radiographic examinations was developed. The virtual environment consisted of a model of a patient, an x-ray machine, and a film. Simulated radiographic images of the patient model could be rendered as perspective projections based on the relative position between the individual models. The software was incorporated in an oral radiology simulator with a training program for interpretation of spatial relations in radiographs. Projection geometry was validated by comparing length dimensions in simulated radiographs with the corresponding theoretically calculated distances. The results showed that projection error in the simulated images never exceeded 0.5 mm. Dental students participated in studies on skill in interpreting spatial information in radiographs utilising parallax. Conventional and simulator based training methods were used. Training lasted for 90 minutes. Skill in interpreting spatial information was assessed with a proficiency test before training, immediately after training, and eight months after training. Visual-spatial ability was assessed with mental rotations test, version A (MRT-A). Regression analysis revealed a significant (P&lt;0.01) association between visual-spatial ability and proficiency test results after training. At simulator training, proficiency test results immediately after training were significantly higher than before training (P&lt;0.01). Among students with low MTR-A scores, improvement after simulator training was higher than after conventional training. Eight months after simulator training proficiency test results were lower than immediately after training. The test results were, however, still higher than before training. In conclusion, the simulation software produces simulated radiographs of high geometric accuracy. Acquisition of skill to interpret spatial relations in radiographs is facilitated for individuals with high visual-spatial ability. Simulator training improves acquisition of interpretative skill and is especially beneficial for individuals with low visual-spatial ability. The results indicate that radiology simulation can be an effective training method.

Energy is consumed every day at home as we perform simple tasks, such as watching television, washing dishes and heating/cooling home spaces during season of extreme weather conditions, using appliances, or turning on lights. Most often, the energy resources used in residential systems are obtained from natural gas, coal and oil. Moreover, climate change has increased awareness of a need for expendable, energy resources. As a result, carbon dioxide emissions are increasing and creating a negative effect on our environment and on our health. In fact, growing energy demands and limited natural resource might have negative impacts on our future. Therefore, saving energy is becoming an important issue in our society and it is receiving more attention from the research community. This thesis introduces a intelligent energy controller algorithm based on software agent approach that reduce the energy consumption at home for both heating and cooling spaces by considering the user’s occupancy, outdoor temperature and user’s preferences as input to the system. Thus the proposed approach takes into consideration the occupant’s preferred temperature, the occupied and unoccupied spaces, as well as the time spent in each area of the home. A Java based simulator has been implemented to simulate the algorithm for saving energy in heating and cooling systems. The results from the simulator are compared to the results of using HOT2000, which is Canada’s leading residential energy analysis and rating software developed by CanmetENERGY’s Housing, Buildings, Communities and Simulation (HBCS) group. We have calculated how much energy a home modelled will use under emulated conditions. The results showed that the implementation of the proposed energy controller algorithm can save up to 50% in energy consumption in homes dedicated to heating and cooling systems compared to the results obtained by using HOT2000.

The aim of this project is to provide a manual wheelchair simulator for advanced wheelchair research within Toronto Rehabilitation Institute‘s Challenging Environment Assessment Laboratory (CEAL). To achieve this, a comprehensive mathematical model of the wheelchair/user system and a fully adjustable physical interface (which mimics various wheelchair configurations) have been developed. The mathematical model is unique in its ability to predict complex motions such as wheelies, and is able to update the wheelchair‘s position in a virtual environment, and calculate the force-feedback required for simulating various slopes and surfaces. The physical interface is used to measure the inputs required by the mathematical model (hand-rim input torques, hand and torso positions, and user centre-of-mass position), and utilizes servo motors to provide force-feedback at the wheelchair‘s hand-rims. Preliminary results comparing real-world wheelchair motion data to the mathematical model‘s predictions are presented, along with the physical interface design and mathematical model development.

This report is about a Thesis for Degree of Bachelor of Science at Linköping University. It describes design of equipment which makes it possible to measure signal and noise quality during data transmission via Asymmetric Digital Subscriber Line, ADSL. The measuring instrument is HP 4934A Transmission Impairment Measuring Set. The equipment was supposed to be used for testing of ADSL systems within Solectron Sweden AB. In fact, the equipment stands for virtual Plain Old Telephone Service, POTS. That is why it simulates all three states that may come up. The states are following:"on hook", ringing,"off hook"(speech transmission). There is a control unit in the design. It changes between different circuit connections to get one of the states. You have to use a computer for control of the equipment. The computer commands are sent to equipment via its serial port via RS232 to the control unit. The equipment is driven with 48 Vdc.
