Cement concrete is widely used throughout the world as a key construction material in civil engineering projects. Being a complex compound comprising of cement, sand, coarse aggregate, admixture and water, its compressive strength is a highly nonlinear function of its constituents, thereby making its modeling and prediction a difficult task. Nature inspired computational techniques, provide an ...

Seat cushions for high-performance aircraft are typically selected for their ability to meet stringent specifications. One of the major criteria is the safety performance during an ejection. To address the design goals of cushion and material selection, a computational modeling method was developed that accounts for component and subsystem testing, component and subsystem modeling, validation c...

Computational Physics Numerical modeling represents an important tool to fulfil the objectives of the group and two domains of application are presently covered: Calculation of radiation fields and Modelling of cold plasmas for material processing. Along with these applications, the group is also involved in improving the available computational capacity with the build up of a Beowulf cluster f...

for large and complex reacting systems, computational efficiency becomes a critical issue in process simulation, optimization and model-based control. mechanism simplification is often a necessity to improve computational speed. we present a novel approach to simplification of reaction networks that formulates the model reduction problem as an optimization problem and solves it using genetic al...

purpose: to develop a computational model for predicting the fluid production and flow, and intraocular pressure (iop) following glaucoma surgery. methods: to help elucidate the interplay of physical factors controlling the distribution and absorption of aqueous humor in sub-conjunctival tissue, and tissue remodeling, a computational model is developed to predict the fluid production in the eye...

Optimization of the complete manufacturing and supply process has become a critical ingredient for gaining a competitive advantage. This article provides a unified mathematical framework for modeling manufacturing cell configuration and raw material supplier selection in a two-level supply chain network. The commonly used manufacturing design parameters along with supplier selection and a subco...
