PURPOSE Crossing the street is an important but risky activity of daily living. If a pedestrian makes a poor street-crossing decision, the consequence could be serious injury or death. In order to advance our understanding of how visual and auditory information is sampled and processed to make street-crossing decisions, an accurate, reliable, and sensitive psychophysical and/or psychometric met...

The size of Ordered Binary Decision Diagrams (OBDDs) is determined by the chosen variable ordering. A poor choice may cause an OBDD to be too large to fit into the available memory. The decision variant of the variable ordering problem is known to be -complete. We strengthen this result by showing that there in no polynomial time approximation scheme for the variable ordering problem unless . W...

In this papec performance improvement of maximumlikelihood sequence estimation (MLSE) receivers operated in jut fading wireless cellular communication channels is investigated. The modijed receiver structure uses a channel classification method based on a decision variable obtainedfrom multiple traffic bursts. By formulating the decision variable using the F-distribution, analytic expressions f...

We consider a firm moving towards a stochastic final destination, to be chosen from a discrete set after a decision period. The decision period itself may be deterministic or stochastic. We assume the firm can move at variable innovation (R&D) speed associated with a monotone nondecreasing variable cost, and it can also stop and move anywhere. There is a fixed cost per time unit "carried" by th...

The present paper deals with the problem of nding a consistent one-variable pattern from incomplete positive and negative examples. The studied problems are called an extension, a consistent extension and a robust extension, denoted by e, ce and re, respectively. The e corresponds an ordinary decision problem of nding a consistent one-variable patterns for given positive and negative examples. ...

This paper presents an efficient simulated annealing (SA) algorithm with a single decision variable to solve the economic load dispatch (ELD) problems. The philosophy involves the introduction of a new decision variable through a prudent mathematical transformation of the relation between the decision variable and the optimal generations. The objectives of ELD problems in electric power generat...

Tree based methods in S or R are extremely useful and popular. For simple trees and memorable variables it is easy to predict the outcome for a new case using only a standard decision tree diagram. However, for large trees or trees where the variable description is complex the decision tree diagram is often not enough. This article describes pinktoe: a tool that converts S tree objects into web...
