From the economic as well as humanitarian point of view, disease which causes premature loss of life or working capacity is of importance and interest. Death before the age of 60 clearly represents a loss to the community of the breadwinner's skill and often entails the burden of the support of his family. The same is true of sickness absenteeism and chronic incapacitating disease which enforce...

A cross-sectional study was carried out on a sample of 26 VDU operators in a post office and a bank, working regularly on video display units. The study aimed at (1) determining the physical working conditions, particularly lighting conditions, (2) assessing employees' complaints, (3) measuring visual defects among operators in VDU workstations. The following results are revealed: (a) ergonomic...

Given a (master) set M of n points in d-dimensional Euclidean space, consider drawing a random subset that includes each point mi ∈ M with an independent probability pi. How difficult is it to compute elementary statistics about the closest pair of points in such a subset? For instance, what is the probability that the distance between the closest pair of points in the random subset is no more ...

The United States Postal Service (USPS) has made numerous efforts to improve the lighting quality and efficiency in their facilities. These efforts have included both traditional retrofits such as the transition to T8 lamps/electronic ballasts and more experimental approaches such as light pipes and sulfur lamps. However, these efforts have focused primarily on their industrial and plant facili...

We introduce the Anonymous Post-office Protocol (AnonPoP), a practical strongly-anonymous messaging system. AnonPoP offers anonymity against globally eavesdropping adversaries that control a majority of AnonPoP’s servers. AnonPoP design combines effectively known techniques such as (synchronous) mixcascade and constant sending rate, with several new techniques including request-pool, bad-server...

The design, development and evaluation of an experimental translation system that aims to aid transactions between a deaf person and a clerk in a Post Office is described. The system uses a speech recognizer to recognize speech from the Post Office clerk and then synthesizes the recognized phrase in British Sign language (BSL) using a specially developed avatar. The main objective in developing...
