Intensive care units are complex and dynamic clinical environments in which the delivery of appropriate and timely care to critically ill patients depends on the integrated and efficient actions of providers with specialized training. The use of realistic clinical simulator systems can help to facilitate and standardize the training of critical-care physicians, nurses, respiratory therapists, a...

VLSI technology CAD (TCAD) requires integrated, physics-based tools for predictive process, device, and (small-scale) circuit simulation. Computational efficiency is desirable, and indeed essential if the TCAD system is to be used in manufacturing CAD involving statistical simulation. Conventional TCAD systems comprise robust, numerical process and device simulators which drive optimization of ...

A graphical simulation system for process planning is presented. Only machined rotational parts are considered in this paper. Feature-based representation is used to build the solid model of the parts and is the basis of the process plan. A simulator is developed to simulate the sequence of the process plan. It provides a mechanism to verify the feasibility of the process plan and to check whet...

This paper introduces a VR city model developed for driving simulation. The project is a part of interdisciplinary multi-year academic research grant. First, the outline of the research is explained. The process of VR city modeling is then introduced. The modeling process of creating road and intersection networks and traffic flow is explained. The system integration with a PC, modeling and VR ...

We describe our use of the CoSMoS process to structure an incremental change of a biological simulation. The domain is auxin transport canalisation. An existing simulator is refactored to handle aspects of 2D and 3D space more efficiently, and enhanced to include more realistically-shaped plant cells. The CoSMoS process supports clear separation of concerns, allowing us to concentrate on the bi...

Dynamic modelling and simulation of a chemical process in emergency conditions is considered. Such modelling and simulation often requires rapid implementation of model changes by the process engineer followed by simulation runs. A simulator with an open architecture structure is presented where the model components (equations) are stored in an object-oriented form in a database, enabling rapid...

The paper discusses a model of phenomenology based on the distinction between sensations and perceptions and it proposes an architecture based on a comparison process between the effective and the expected sensations generated by a 3D robot/environment simulator. The phenomenal perceptions are thus generated by the simulator driven by the comparison process. The paper contributes to the conscio...

With the advent of modern, multithreaded programming languages, it has become vitally important to describe in a clear and understandable way how threads interact through memory. The existing Java Memory Model is fundamentally broken; the process of creating an appropriate replacement has demonstrated exactly how deeply complex these issues can be. A formal specification [MP01a] of a replacemen...

Abstract A comminution process is a material size reduction and separation which primarily used in the aggregates minerals processing industry. Knowledge related to equipment’s operation, raw properties, operational strategies, control system, maintenance, etc. needed design capable plant. New needs are arising from industry for existing crushing plants such as investigation improvements, upsca...
