Dynamic Behavior of a Perceptron-Type Element

Abstract

This paper deals with a perceptron-type element in which variable weights change automatically following a certain rule of growth. An analysis of its dynamic behavior is described together with some simulation results.The element is a summing device. Its output y(t) is a weighted sum of its inputs xi(t),i=The inputs xi(t) are assumed to be zero-mean signals, but not restricted to binary signals. Changes in the weights wi(t) are described by the differential equations A detailed investigation of the solutions of the above equation shows that the element has a strong tendency to separate its inputs into a family of principal components and to pick out the greatest component as its outpat. This property enables it to perform a variety of types of information processing such as factor analysis, signal filtering, pattern dichotomy, majority decision logic and memory.

Fluctuation formulas in molecular-dynamics simulations with the weak coupling heat bath

“…This scaling scheme will be presented with applications to other constant temperature or/and pressure methods in a forthcoming paper. 19…”

“…However, this is not performed under accuracy in the Verlet algorithm, where O(⌬t 2 ) is ignored. With the ''modified'' velocity scaling scheme recently proposed by the author, 19 integrations can be performed within the Verlet's accuracy unless is O(⌬t).…”

Engine Test Experience With HVOF WC-Co Coated Fan Blade Dampers

“…The result is a loss of coating performance or cracks propagating through the mid-span damper resulting in loss of the damper and in some cases complete engine failure. Residual stresses have in many racps been identified as, or suspected to be a contributing factor of shortened service life for thermal spray coatings [1], [2]. Residual stresses in thermal spray coatings have been linked to bending strength, fatigue life, bond strength and microstructures [3], [4], [5].…”

“…The magnitude of the residual stress and whether it is tensile or compressive can have a significant influence on coating performance. A compressive residual stress zone near the surface of a material, can hinder surface crack initiation and slow down crack propagation [6], [2].…”
