The artificial neural networks (ANNs) have been applied to various hydrologic problems recently. This research demonstrates static neural approach by applying Modular feedforward neural network to rainfall-runoff modeling for the upper area of Wardha River in India. The model is developed by processing online data over time using static modular neural network modeling. Methodologies and techniq...

& Conclusions – Dependability evaluation is a basic component in the assessment of the quality of repairable systems. We develop here a general model specifically designed for software systems that allows the evaluation of different dependability metrics, in particular, of availability measures. The model is of the structural type, based on Markov process theory. In particular, it can be viewed...

Flowsheet simulation, an important building block in chemical process development and design, generally requires the solution of a nonlinear system equations. Such simulation can fail if either no exists for chosen specifications or initial values solver are unfavorably. In this work, to overcome such convergence failures, AI-based surrogate models trained unit operations flowsheet then interco...

Model-based development promises to increase productivity by offering modeling languages tailored to a specific domain. Such modeling languages are typically defined by a metamodel. In response to changing requirements and technological progress, the domains and thus the metamodels are subject to change. Manually migrating existing models to a new version of their metamodel is tedious and error...

MOTIVATION Need for software to setup and analyze complex mathematical models for cellular systems in a modular way, that also integrates the experimental environment of the cells. RESULTS A computer framework is described which allows the building of modularly structured models using an abstract, modular and general modeling methodology. With this methodology, reusable modeling entities are ...

[email protected] Abstract — As powerful as Building Information Modeling (BIM) tools are in modeling the built environment, current BIM strategies limit the size of facilities that can be modeled while increasing the time needed for modeling and the quality of BIM models produced. In the same way that prefabricated modular construction techniques are improving the speed and quality of const...

This paper describes the control architecture and laws of a new concept Modular Iron Bird aimed at reproducing flight loads to test mobile aerodynamic surface actuators for small medium size aircraft Unmanned Aerial Vehicles. The iron bird system must guarantee actuation counteracting forces. On one side, hydraulic actuator simulates hinge moments acting on due inertial effects during flight; o...

SUMMARY The dynamic modeling and trajectory following issues are addressed for mobile modular manipulators. Simulations are performed to validate the proposed algorithms. I. INTRODUCTION Usually, modular manipulators are mounted on a fixed base whose mobility is constrained. We attach a mobile platform to the bottom of the manipulator to increase workspace. In related research work, dynamic cha...
