This paper investigates some of the man~estations and major forces driving the emergence of the new economy. A model of the virtual enterprise is proposed and investigated in the context of a virtual industry value chain. The transition to the virtual economy is definitely technology driven but is also shaped by social, economic, institutional forces. As such, it raises a number of significant ...

This paper presents i-AA1, a constructive, incremental learning algorithm for a special class of weightless, self-organizing networks. In i-AA1, learning consists of adapting the nodes’ functions and the network’s overall topology as each new training pattern is presented. Provided the training data is consistent, computational complexity is low and prior factual knowledge may be used to “prime...

Liquid bridges have been the focus of numerous theoretical and experimental investigations since the early work by Plateau more than a century ago. More recently, motivated by interest in their physical behavior and their occurrence in a variety of technological situations, there has been a resurgence of interest in the static and dynamic behavior of liquid bridges. Furthermore, opportunities t...

(MCS), but this has rarely incorporated any utilisation of weightless neural systems(WNS) as the combiner of an MCS ensemble. This paper explores the application of weightless networks within the multi-classifier environment by introducing an intelligent multi-classifier system using a WNS called the Enhanced Probabilistic Convergent Neural Networks (EPCN). The paper explores the use of EPCN by...

An approximate two-dimensional model for indentation of blunt objects into various types of rigid-perfectly plastic cohesive-frictional material is derived. Particular emphasis is placed on considering indentation as a process involving evolution of the boundary of material displaced by the indenter. Force-penetration relationships are obtained by an incremental approach utilizing key kinematic...

The inverse problem is posed of stabilizing a spherical pendulum (a mass point at the end weightless solid rod length l ) in given position using high-frequency vibration suspension point. determined by angle between and gravity acceleration vector. For any pendulum, series oblique parameters (amplitude velocity vector vertical) were found that stabilize this position. From obtained solutions, ...
