Energy Relaxation in In0.53ga0.47as/Inp Quantum Wires
In low-dimensional semiconductor structures significant modifications of the carrier scattering rates are expected due to the reduced number of final states that fulfill both energy and momentum conservation. ...

Introduction—Scanning the Symposium
In his revolutionary experiments of 1895, Marconi achieved transmission of coded radio signals over distances up to 2 km. Six years later, he succeeded in the first transmission of telegraphic signals across t...

A Region-Based Video Coder Using a Forward Tracking Active Mesh
In an earlier study, we have reported the use of an active mesh representation for describing a video sequence [1]. In this representation, a scene adaptive mesh is generated for an initial frame, such that, the ...

A new subgraph of minimum weight triangulations
In this paper, two sufficient conditions for identifying a subgraph of minimum weight triangulation of a planar point set are presented. These conditions are based on local geometric properties of an identifyi...

Optimal algorithms for circle partitioning
Given a set of n points F on a circle and an integer k, we would like to find a size k subset of F such that these points are “evenly distributed” on the circle. We define two different criteria to capture the in...

Fixed topology steiner trees and spanning forests with applications in network communications
We present pseudo-polynomial time algorithms for fixed topology Steiner tree problems with various time-delay constraints. We study the spanning forest problem with bandwidth constraint. A polynomial-time algo...

A matrix representation of phylogenetic trees
In this paper we begin by describing two currently used methods for evaluating phylogenetic trees, one proposed by Fitch and Margoliash [5] and the other proposed by Saitou and Nei [7]. Both methods are heuris...

A novel associative network accommodating pattern deformation
In this paper we propose a novel associative network model which is able to associate a pattern with deformed versions of itself. The model is composed of a set of logical units (viewed as a set of marbles) and a...

A new type of unsupervised growing neural network for biological sequence classification that adopts the topology of a phylogenetic tree
We propose a new type of unsupervised growing self-organizing neural network that expands itself following the taxonomic relationships existing among the sequences being classified. The binary tree topology of...

High-level execution time analysis
A compositional algebra, called mMCAN, for the execution time analysis of highlevel software processes is introduced. In mMCAN, processes can be concatenated, concurrently executed, and recursively invoked. We...
