Human motion models for reaching tasks facilitate the design of many systems such as computer and cellphone interfaces, cockpits, and assembly lines. Fitts’ Law specifies a logarithmic two-parameter relationship between motion duration and the ratio of target distance over target size, and more recent models consider square root and modified logarithmic relationships. This paper contributes new...

In this paper we investigate parallel searching on m concurrent rays. We assume that a target t is located somewhere on one of the rays and that a group of m point robots has to reach t. Furthermore, we assume that the robots have no way of communicating over distance. Given a strategy S we are interested in the competitive ratio which is deened as the ratio of the time needed by the robots usi...

1.0 Introduction The contrast of a given feature at a specific wavelength of light is determined by the radiance of that feature and the radiance of the background or adjacent feature against which it is viewed. Target/Sky contrast (C) is defined as the ratio of the difference between the feature (target) and the background sky radiance to the background sky radiance: where N stands for radianc...

This study examines Kahneman and Tversky's prospect theory in the commercial banking industry. Prospect theory predicts increased risk-taking behavior in the presence of below-target outcomes. Fishburn redefined risk (commonly measured as dispersion about the mean outcome) as the integral of a function that is based on distance below target outcome. This study uses rates of return and the prima...

Target classification fusion problem in a distributed, wireless sensor network is investigated. We propose a distance-based decision fusion scheme exploiting the relationship between sensor to target distance, signal to noise ratio and classification rate, which requires less communication while achieving higher region classification rate when compared to conventional majority-vote based fusion...

In recent years, many researchers have made a lot of works and achieved remarkable results. The system effect distance is deduced from different aspects in [1, 2]. Target range is obtained based on the target movement model in [3]. [4] studies the passive ranging of ground target in mono-static and single band condition based on radiance difference between target and background. Ranging express...

In this paper we introduce three natural “score statistics” for testing the hypothesis that F (t0) takes on a fixed value in the context of nonparametric inference with current status data. These three new test statistics have natural intepretations in terms of certain (weighted) L2 distances, and are also connected to natural “one-sided” scores. We compare these new test statistics with an ana...
