In this paper, we investigate the bulk service queue with Bernoulli vacation schedule and restricted admissibility introduced and studied by Madan and Abu-Dayyeh, [Revista Investigacion Operacional, Vol.24, No.2, pp.113-123, 2003]. Madan and Abu-Dayyeh assume exponentially distributed service times while we allow these times to be generally distributed. We obtain various performance measures th...

Moment invariants are evaluated as a feature space for pattern recognition in terms of discrimination power and noise tolerance. The notion of complex moments is introduced as a simple and straightforward way to derive moment invariants. Through this relation, properties of complex moments are used to characterize moment invariants. Aspects of information loss, suppression, and redundancy encou...

A new upper bound is given on the number of ways in which a set of N points in Rn can be partitioned by k parallel hyperplanes. This bound improves upon a result of Olafsson and Abu-Mostafa [IEEE Trans. Pattern Analysis and Machine Intelligence 10(2), 1988: 277-281]; it agrees with the known (tight) result for the case k = 1; and it is, for fixed k and n, tight to within a constant. A previousl...

Introduction During the course of archaeological research completed in the area of Bilad al-Qadim in the northeast of Bahrain in 2001, trial excavations and survey were undertaken at the spring of Abu Zaydan (N26 12¢ 24.5¢¢ E050 32¢ 50.7¢¢). The focus of this research project was to investigate the Islamic period on Bahrain, hence the remains recorded at Abu Zaydan were unexpected, comprising a...
