The local binary pattern operator is an image operator which transforms an image into an array or image of integer labels describing small-scale appearance of the image. These labels or their statistics, most commonly the histogram, are then used for further image analysis. The most widely used versions of the operator are designed for monochrome still images but it has been extended also for c...

In this paper a control architecture and system is proposed which allows human supervisory for teleoperators in a time delayed environment. The integrated operation concept defines two phases. The first phase is alternatively an automatic or operator driven "preparation" phase, including off-line planning facilities with real-time simulation on 3D computer graphics for verification of robust op...

Using formal tools in computer science to describe games is an interesting problem. We give games, exactly two person games, an axiomatic foundation based on the process algebra ACP (Algebra of Communicating Process). A fresh operator called opponent’s alternative composition operator (OA) is introduced into ACP to describe game trees and game strategies, called GameACP. And its sound and compl...

The paper discusses main ideas of design principles and results of practical implementation of ICT for assessment and prediction of power plant operator fitness-for-duty. They are discussed reasons of discrepancy of operator psychophysiological opportunities to occupational requirements that can reduce his/her reliability and general fitness-for-duty. Principles of functioning of the system for...

Simpson, A.K., A characterisation of the least-fixed-point operator by dinaturality, Theoretical Computer Science 118 (1993) 301-314. The paper addresses the question of when the least-fixed-point operator, in a Cartesian-closed category of domains, is characterised as the unique dinatural transformation from the exponentiation bifunctor to the identity functor. We give a sufficient condition o...

A $it{weighted~slant~Toep}$-$it{Hank}$ operator $L_{phi}^{beta}$ with symbol $phiin L^{infty}(beta)$ is an operator on $L^2(beta)$ whose representing matrix consists of all even (odd) columns from a weighted slant Hankel (slant weighted Toeplitz) matrix, $beta={beta_n}_{nin mathbb{Z}}$ be a sequence of positive numbers with $beta_0=1$. A matrix characterization for an operator to be $it{weighte...

Data movement across computer memory hierarchy and across hosts of distributed systems is known to be a limiting factor for applications processing large data sets. We use the Data Cube Operator on an Arithmetic Data Set, called ADC, to benchmark computer capability to handle large datasets. To compute the operator we implement a parallel algorithm that computes a view from the smallest parent....

Power haulage accounts for the greatest number of fatalities in Canadian, Australian, American, Indian, and Spanish mines, and is the fourth leading cause of fatal accidents in underground African mines. However, this rate is expected to grow with a move toward increased power haulage and less manual labour in Africa. Many of the fatal injuries have been associated with load-haul-dump (LHD) ope...

The completely positive operators, which can be viewed as a generalization of the nonnegative matrices, are maps between spaces of linear operators arising in the study of C*-algebras. The existence of the operator analogues of doubly stochastic scalings of matrices is equivalent to a multitude of problems in computer science and mathematics, such rational identity testing in non-commuting vari...
