In this paper we develop a new approach to the study of uncountable fundamental groups by using Hurewicz fibrations with unique path-lifting property ( lifting spaces for short) as replacement covering spaces. particular, consider inverse limit sequence X . It is known that path-connectivity can be expressed means derived functor lim ← 1 , which is, however, notoriously difficult compute when g...

this paper demonstrates a preliminary investigation of geometry, function and its relation to dfx principles, namely dfm (design for manufacturing). this is the starting point for research on the development of an expert system that assesses design goals along dfx principles in a feature-based cad environment. there is a need for a deeper level of understanding of the relationship between geome...

Inverse kinematics solutions of a reconfigurabie robot system built upon a collection of standardized components is dificult to obtain because of its varying configuration. This paper addresses the formulation of a generic numerical inverse kinematics model and automatic generation of the model for arbitrary robot geometry including serial type and branching type geometry. Both revolute and pri...

An automated method of modelling the electrical properties of the human thorax from horizontal section data such as computerized tomographic scans has been used to develop both forward and inverse transformations between epicardial and body surface potential distributions. Eleven torso models with varying geometry and organ configurations have been studied. For the forward calculations, a stand...

An ultimate goal of materials science is to deliver with desired properties at will. In the theoretical study, a standard approach consists constructing Hamiltonian based on phenomenology or first principles, calculating physical observables, and improving through feedback. However, there also an that bypasses such cumbersome procedure, namely, obtain appropriate directly from properties. Solvi...
