This paper presents the fuzzy induced heavy ordered weighted averaging (FIHOWA) operator. It is an aggregation operator that uses the main characteristics of three well known aggregation operators: the heavy OWA, the induced OWA and the fuzzy OWA operator. Therefore, this operator provides a parameterized family of aggregation operators that includes the OWA operator and the total operator as s...

This paper addresses a need for practical human machine interface (HMI) design principles for safety-related computer controlled systems. Most HMI design principles and guidelines focus on aspects of usability. Whilst usability is important for reducing the incidence of human error, more is required of a safe human machine interface. A safe HMI design must reduce incidence of human error but eq...

An experiment was carried out to estimate the effect of sound feedback on the work of a plant operator. Eight students of computer science operated a process simulation program of an assembly line with computer numeric controlled (CNC) robots. Relevant information of disturbances and machine breakdowns was given only in a visual (test condition 1), and in visual and audible form (test condition...

A graphical interactive software training system as disclosed comprising a host computer sub-system operatively connected to a graphic computer sub-system providing training courses for use by a human operator. The training system functions without reference to a control program. It includes a series of stand-alone and isolated pictures having command functions embedded thereon requiring · an i...

Laplace–Beltrami operator and its discretization play a central role in the fields of image processing, computer graphics, computer aided geometric design and so on. In this paper, a discrete scheme for Laplace–Beltrami operator over quadrilateral meshes is constructed based on a bilinear interpolation of the quadrilateral. Convergence results for the proposed discrete scheme are established un...

Growing use of computers in safety-critical systems increases the need for Human Computer Interfaces (HCIs) to be both smarter to detect human errors and better designed to reduce likelihood of errors. We are developing methods for determining the likelihood of operator errors which combine current theory on the psychological causes of human errors with formal methods for modelling human-comput...

in this paper we study properties of symbols such that these belong to class of symbols sitting insidesm ρ,φ that we shall introduce as the following. so for because hypoelliptic pseudodifferential operatorsplays a key role in quantum mechanics we will investigate some properties of m−hypoelliptic pseudodifferential operators for which define base on this class of symbols. also we consider maxi...

In this paper we discuss a model of quantum computer in which a state is an operator of density matrix and gates are general quantum operations, not necessarily unitary. A mixed state (operator of density matrix) of n two-level quantum systems is considered as an element of 4n-dimensional operator Hilbert space (Liouville space). It allows to use a quantum computer model with four-valued logic....
