In this paper we discuss a modular multi-sense perception system for DIVAs virtual agents. It is based on the idea that local environmental influences are constantly sensed by one or more of an agent's senses (sight, hearing, smell, etc.). The perception system is extensible and modifiable and allows users to dynamically modify how an agent perceives its environment at execution time. This paper focuses...
In order to solve problems caused by various format of simulation data and complex operation flow on collaborative simulation from different software in the development of virtual prototype technology, this article analyzes and designs the SD&PMS(Simulation Data &Process Management System)frames based on three key capacity of simulation capacity management. They are Simulation organization...
In this paper we present a program tool that was developed for the simulation of temperatures inside the cooling appliance. The simulator is used to check the performance of the appliance at different settings of control parameters. These simulations replace the part of the measurements, which are time consuming due to the slow thermal processes, but are needed in the appliance development process...
Modular construction is common practice for building industrial plants in the Alberta oil sands region, Canada because of the savings in cost and schedule, and improving safety and quality. Each module represents a unique construction project. Thus, modular construction is considered as multi-project construction. Scheduling and effective allocation of resources (e.g., space, skilled crew, construction...
This work aims to analyze, with the System Dynamics simulation, the impacts of a new supermarket opening in terms of the traffic flows in the surroundings of a determined urban zone, in order to help decision makers to find the most suitable area and the proper number of car parks and counters to satisfy a certain customer level service, avoiding high waiting times and, consequently, customer losses...
Healthcare delivery systems around the world are faced with growing demand to provide a better-quality standard of care and at the same time keep the cost and resource utilization minimal. Statistics reveal that diabetes is a major issue in the healthcare industry and there is a strong need to address this problem in order to improve and reduce the cost of its treatment. Furthermore, evidence of the...
According to the application of the planet detection, visual localization of the planet rover was studied in this paper. A corresponding robot arm plane localization simulation system for real rover robot arm based on stereo vision and virtual reality was developed. The system provided motion parameters of virtual robot arm to real arm by means of off-line teaching, which ensured the rover's safety...
A calculation on simulating waterflood evolution has been suggested. Dynamic emulation technology for water body evolution has been studied deeply supplied by digital model of elevation discrepancy. breadth-first-search is referred to as the basic calculation on waterflood dynamic evolution that controls boundary conditions and also provides a practical solution; on the development platform for Visual...
The mathematical model of double pendulum system is established based on the Newton's laws of motion and is linearized under the approximate condition when the pivot angle is very small. The above model is verified based on the simulation by MATLAB. The controllability and its relationship with parameters of the system is researched. Simulation result shows that the system is controllable when the...
With the development of network technology, computer network is characterized as an uncontrollable, variable and unpredictable infrastructure, this brings great difficulty of verify, defining, debugging and comparing the new schemes. Network simulation technology is proposed to test, appraise, and verify means available. This paper designs and implements an intelligent analyzing tool for NS2 traces,...
Simulation plays an important role in both academic research and industrial development and manufactory. The users' requirements for simulation are often complex and diverse. It is time consuming and error-prone for users to build different simulation environments manually to conduct their simulation tasks. An Automatic Simulation Environment Customizing Service for Cloud Simulation Center is presented...
With the development of automotive industry and transportation, the safety of transportation is huge invisible trouble by bringing great convenience to human being for many years. As result, the reappearance for the simulation of traffic accidents scene is essential. On the other side the reappearance of traffic accidents is not only the method to evaluate the responsibility, analysis the cause, but...
The outbreak of pandemic influenza A (H1N1) around the world has caused significant economic loss and human death. It is a urgent challenge to improve our response to pandemic influenza A (H1N1) outbreaks, and avoid its epidemic. Computer simulation is a pragmatic and effective methodology for analyses of influenza A (H1N1). A spatially explicit epidemiological simulation system is proposed to study...
In order to seek a new simulation modeling method of container terminal systems and to overcome some shortcomings of the existing methods, a digital logical circuit simulation model of unloading operation was build for simulating the working condition of container handling equipments and logic events by software Electronics Workbench5.0. Simulation results show that the model can accurately reflect...
The simulation model of railway vehicle semi-active vibration isolation system is constructed by application of Matlab / Simulink software, and the dynamics simulation on railway vehicle semi-active vibration isolation system is carried out. In the case of random input, the vibration isolation characteristics (such as distance of vibration isolation, vibration acceleration response variance) of railway...
Because of the operation characters of power system, high-power electronic devices, such as active power filter (APF), could not be tested fully in field before commissioning. To solve this problem, the hardware-in-the-loop system (HIL) which is comprised of real-time digital simulator (RTDS) and the APF is used to test the functionality and performance of the APF in place of the real system. We introduce...
Traditional network plan with the fixed duration for every activity is not suitable for actual construction management, because in actual project cases, the duration of every activity has many occasional factors. Using the Stateflow software, a simulation modeling for network plan which has flexible durations is established. At the same time, an example of flexible network plan is simulated. The simulation...
Belt simulation is the key point of virtual prototyping (VP) technology for belt conveyor. ADAMS can carry on the simple conveyor belt simulation. For its low precision and heavy work, ADAMS is not suitable for belt conveyer VP modeling and simulation. A new simulation method based on RecurDyn is introduced in this paper. The conveyor belt is divided into finite discrete micro belt segments. With...
Current concepts for the simulation of transport systems within industrial production plants can be divided into two non-overlapping categories. Time-based concepts simulate physics for few carriers whereas event-based concepts handle many carriers at high abstraction level. We present a new hybrid hierarchical time-based/event-based method to combine the benefits of both concepts. New methods allow...
Using three-dimensional finite element to analyze the bridge structure, the article use OpenGL to research bridge three-dimensional modeling and render realistic graphics.
