ABSI1lACF An integrated e'Q>en system architecture and strategy for diagnosis of dynamic systems with feedback loops a¥ s~chronous or asynchronous state transitions is presented. The dynamic system under diagnosis is modeled' using structural and behavioral representations in multiple levels of abstraction I The diagnosis process inte~tes shallow ~d deep expertise. It recursively navigates thro...

The simulator is an R package that streamlines the process of performing simulations by creating a common infrastructure that can be easily used and reused across projects. Methodological statisticians routinely write simulations to compare their methods to preexisting ones. While developing ideas, there is a temptation to write “quick and dirty” simulations to try out ideas. This approach of r...

This paper discusses the balancing of a groundbased satellite simulator. The simulator uses an air bearing as the primary method for the emulation of the frictionless environment of space. Of particular concern for accurate simulation is system balancing. 'Balancing' refers to the process of moving the center ofmass(CM) of the simulator near to the center of rotation(CR) of the air-bearing to r...

PURPOSE To evaluate a haptic-based simulator, MicroVisTouch™, as an assessment tool for capsulorhexis performance in cataract surgery. The study is a prospective, unmasked, nonrandomized dual academic institution study conducted at the Wilmer Eye Institute at Johns Hopkins Medical Center (Baltimore, MD, USA) and King Khaled Eye Specialist Hospital (Riyadh, Saudi Arabia). METHODS This prospect...

Data acquisition systems have a direct impact on interactivity and authenticity to the car driving simulator. According requirements of vehicle simulator complete multi-channel data processing with high speed precision, set real-time system was designed. The uses STM32F103ZET6 chip process acquisition, communicates host computer through serial port. experimental results show that designed has g...

Article history: Received: August 15, 2009. Received in revised form: November 24, 2009. Accepted: November 29, 2009. This paper describes a virtual reality (VR)-assisted robotic surgery simulator for bone surgery training. A trainee surgeon holds the haptic robot stylus and manipulates it three-dimensionally to interact with the virtual bone. The robotic simulator allows the trainee surgeon to...

During the development and enhancement of simulator systems, new technologies are incorporated to improve the training capabilities of the system. The degree to which changes to the simulator system improve training capabilities in anticipated areas is of primary interest; however, an evaluation of benefits from newly incorporated technologies should consider the impact on training capabilities...

In this paper, a time and memory-efficient diagnostic fault simulator for sequential circuits is first presented. A distributed diagnostic fault simulator is then presented based on the sequential algorithm to improve the speed of the diagnostic process. In the sequential diagnostic fault simulator, the number of fault-pair output response comparisons has been minimized by using an indistinguis...

In this work, a procedure to simulate the MD (molecular distillation) process for lactic acid purification was developed. The simulation was carried out with the aid of the Aspen Plus Process Simulator. Flash vessel was used to represent the MD process since the software does not present this unit operation. The simulation results with efficiency factors were in agreement with previously report...
