It has been recently suggested by Arkani-Hamed, Dimopoulos and Dvali that gravity may become strong at energies not far above the electroweak scale and thus remove the hierarchy problem. Such a scenario can be tested at both present and future accelerators since towers of Kaluza-Klein gravitons and associated scalar fields now play an important phenomenological role. In this paper we examine se...

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...

Hinton [6] proposed that generalization in artificial neural nets should improve if nets learn to represent the domain's underlying regularities . Abu-Mustafa's hints work [1] shows that the outputs of a backprop net can be used as inputs through which domainspecific information can be given to the net . We extend these ideas by showing that a backprop net learning many related tasks at the sam...

Dr Evatt said he proposed to explain, in a very simple manner, the system by which Private Thomas Atkins when struck down by a bullet, say at Abu Klea, was cared for, transported to the rear, and thence to London or Edinburgh, as the case might be, and to show the various medical units and organizations through which he must pass. The medical system that now existed provided for this duty in a ...

Preparative open pyrolysis products of kerogen isolated from a Holocene microbial mat collected in Abu Dhabi (United Arab Emirates) contain homologous series of monomethylalkanes (MMAs, C16±C29). The isomer and carbon number distributions of these branched alkanes closely match those of MMAs in ancient sediments and oils. It is proposed that monomethylalkanes in oils and in thermally mature anc...
