This article sets forth a detailed theoretical proposal of how the truth of ordinary empirical statements, often atomic in form, is computed. The method of computation draws on psychological concepts such as those of associative networks and spreading activation, rather that the concepts of philosophical or logical theories of truth. Axioms for a restricted class of cases are given, as well as ...

Techniques that traditionally have been useful for retrieving same domain analogies from small single use knowledge bases such as spreading activation and indexing on selected features are inadequate for retrieving cross domain analogies from large multi use knowledge bases In this paper we describe Knowledge Directed Spreading Activation KDSA a new method for retriev ing analogies in a large s...

In naturally occurring speech and gesture, meaning occurs organized and distributed across the modalities in different ways. The underlying cognitive processes are largely unexplored. We propose a model based on activation spreading within dynamically shaped multimodal memories, in which coordination arises from the interplay of visuo-spatial and linguistically shaped representations under give...

Abstract In order to improve the starved lubrication condition of rolling bearings, three kinds textures, namely dimple, groove texture, and gradient were developed on guiding surface thrust ball bearings in this study. The results show that texture has one-way self-driving function liquid droplets. root mean square (RMS) value vibration acceleration textured bearing (GGB) decreased by 49.1% ku...

An adjuvant is any material added to a herbicide spray solution to enhance or modify the performance of the solution. Adjuvants can be divided into two general categories: spray modifiers and activators (Kirkwood, 1994). Spray modifiers are those adjuvants that change the wetting, spreading or sticking characteristics of the spray solution. This is primarily accomplished by a modification in th...

Radiation therapy for oral and maxillofacial tumors could damage bone marrow stromal cells (BMSCs) in jaw, which caused dental implant failure. However, how radiation affects BMSCs on SLA (sandblasted with large-grits, acid-etched) surfaces is still unknown. The aim of this study was to investigate effect of different dose of γ-radiation on BMSCs on SLA and PT (polished titanium) surfaces. Rat ...

  Spreading and coating of nano and micro droplets on solid surfaces is important in a wide variety of applications including plasma spray coating, ink jet printing, DNA synthesis and etc. In spraying processes, most of droplets collide obliquely to the surface. The purpose of this article is to study the distribution of nano and micro droplets spreading when droplets impact at an oblique a...
