Using HOL4, we mechanise termination and correctness for two unification algorithms, written in a recursive descent style. One computes unifiers for first order terms, the other fo...
The navigation activity is an every day practice for any human being capable of locomotion. Our objective in this work is to reproduce this crucial human activity inside virtual e...
In this paper we describe a unique type of knowledge management systems virtual reality-enabled multi-user virtual environments with spatialised semantic structures. They are des...
—The methodologies to calculate failure probability and to estimate the reliability of fatigue loaded structures are developed. The applicability of the methodologies is evaluate...
We show that for random bit strings, Up(n), with probability, p = 1 2 , the firstorder quantifier depth D(Up(n)) needed to distinguish non-isomorphic structures is (lg lg n), with...
