Two types of vehicles are considered the simulation, namely user-driven vehicle at center simulation and other interact with it its surroundings, which configure developed model. Simulation performed reduced zone, called control surrounding vehicle....

A sensitivity analysis has been performed to assess the influence of inertial properties railway vehicles on their dynamic behaviour. To do this, 216 simulations were modifying, one at a time, masses, moments inertia and heights centre gravity carbody, bogie wheelset. Three values assigned each parameter, corresponding percentiles 10, 50 90 data set stored in database vehicles. After processing results these simulations, analysed parameters sorted by increasing influence. It was also found...

Electrical dimensioning design in a railway infrastructure has high complexity and is strongly nonlinear. There are several parameters constraints to take into account. The presented methodology working improve the decision making about design, hence developing an expert system. final set of possible solutions that method achieved based on pair main objectives. On one hand installation costs, environmental impact, electrical components costs such as catenary, traction substations, neutral...

The World Health Organization estimates that 17 million people die of cardiovascular disease, particularly heart attacks and strokes, every year. Most strokes are caused by a blood clot occludes an artery in the cerebral circulation process concerning removal this obstruction involves catheterisation. fundamental object presented study consists determining optimizing necessary simulation model corresponding with zone to be implemented jointly other Mechanical Thrombectomy Device models,...

This paper describes a model for traffic simulation of an urban environment and its implementation in driving simulator. The simulator is also able to reproduce realistic accidents. In order attain real-time simulation, the has been partitioned considering city as divided into segments road, junctions, sectors that minimize interaction between cars involved considered only control zone centered on driven vehicle. Simplified dynamic vehicle models have used when vehicles are not accident,...

Increasing industrial competitiveness has led to an increased global interest in condition monitoring. In this sector, rotating machinery plays important role, where the bearing is one of most critical components. Many vibration-based signal treatments are already being used identify features associated with faults. The information embedded such employed construction health indicators, which allow for evaluation current operating status machine. work, use contour maps represent diagnosis map...

This paper describes a model capable of simulating large-scale traffic in an urban environment. The goal is this work the realistic and detailed simulation traffic, reproducing behavior each vehicle involved environment individually. has been developed order to be integrated immersive driving simulator, where position center reproduces what happens around them. general based on following theory. Depending size simulated, number vehicles involved, density, can studied as whole or segmented...

For engineers, computer simulation, is a basic tool since it enables them to understand how systems work without actually needing see them. They can learn they in different circumstances and optimize their design with considerably less cost terms of time money than if had carry out tests on physical system. However, simulation be reliable essential for the model validated. There wide range commercial brands market offering products electrical domain (SPICE, LabVIEW PSCAD,Dymola, Simulink,...

Nowadays the use of complex models has increased requirements simulation tools and techniques for working analyzing with different domains at same time. This work focuses on study Scanner servocontrols a fighter aircraft. The model feature integrating various physical into system (electrical, mechanical control environments) dimensions in each domain. technique used is Bond Graph (BG), which typically fields where coexist, just as case we are dealing with, such fundamental. At beginning...

This paper describes a model for the traffic simulation of an urban environment. Its main application is implementation in driving simulators. Since it focused on real-time applications, compromise must be achieved between realism and computation speed obtained. In order to attain simulation, environment has been partitioned, city being considered as divided into segments road, junctions, sectors that minimize interaction cars involved with only control zone centred driven vehicle....

This article describes a program that uses virtual reality techniques to allow mechanisms be viewed, moved and manipulated. These can assembled/unassembled checked see if they work properly. A environment is used the mechanism seen by different ways using head-mounted display or stereoscopic glasses. an example of how it possible adapt traditional subjects, like engineering drawing, new technologies visualization simulation. In order for via Internet, supports VRML file view with Internet...

They can learn they in different circumstances optimize their design with considerably less cost terms of time money than if had carry out tests on physical system. There wide range commercial brands the market offering products for electrical simulation. These are powerful tools, but require engineer have perfect knowledge field. This...

The current paper presents a procedure for converting to minimal set the dynamic equations of system modelled with bond graphs starting from large differential-algebraic including any type topological loops and zero-order causal paths (ZCPs). This is composed only differential expressed in terms degrees freedom system. These are suitable use real-time simulations. Initially, flows corresponding inertances displacements associated compliances used establish find ZCPs Two different methods...

Tiled projector displays are a common choice for training simulators, where high resolution output image is required. They cheap the that they can reach and be configured in many different ways. Nevertheless, such kinds of require geometric color correction so composite looks seamless. Display an even bigger challenge when projected images include dark scenes combined with brighter scenes. This usually problem railway simulators train positioned inside tunnel black offset effect becomes...
