Development of a dynamic simulation code for the sulfur-iodine process coupled to a very high-temperature gas-cooled nuclear reactor
One of the key issues in developing a sulfur-iodine (SI) thermochemical hydrogen production technology is how to operate the SI process, including the start-up operation procedure. In order to effectively establish a start-up procedure, it is necessary ...

Currently, the widely used notion of activity is increasingly present in computer science. However, because this notion is used in specific contexts, it becomes vague. Here, the notion of activity is scrutinized in various contexts and, accordingly, put ...
Modeling and simulation for product design process
Descriptive simulation finds the performance measure of a system, given a particular value for the input parameters. Inverse simulation reverses this and attempts to find the controllable input parameters required to achieve a particular performance ...
Using a rate equations approach to model World population trends
According to UN data and projections, the World population will begin to decrease by the middle of this century. This paper uses rate equations (fully analogous to those employed in condensed matter physics) to simulate the time evolution of World ...
Bond graph representations of hydraulic pipelines using normal modes with dissipative friction
The one-dimensional (1-D) unsteady-pressure-flow equations of hydraulic pipeline can be approximated and solved numerically using a finite-mode approach. This paper deals with constructing bond graph representations for the hydraulic pipelines with ...

Microscopic traffic simulation tools are increasingly being employed as an integral part of modeling vehicular traffic and pedestrian activity. However, the complexity of pedestrians' behaviors and their interactions with the various components of the ...
Hardware-in-the-loop simulation for testing of electro-hydraulic fuel control unit in a jet engine application
A hardware-in-the-loop (HIL) simulation framework for testing an experimental electro-hydraulic fuel control unit (FCU) within the numerical simulation of a turbojet engine is presented. The HIL simulator is used to create control signals, and hydraulic ...
Modeling turbo-expander systems
Turbo-expander systems have long been used instead of regulators, but they have recently received attention as a driving medium for power electrical generators. These systems typically replace the regulator valves that reduce the gas pressure in gas ...
