Qualitative calculi play a central role in representing and reasoning about qualitative spatial and temporal knowledge. This paper studies distributive subalgebras of qualitative calculi, which are subalgebras in which (weak) composition distributives over nonempty intersections. It has been proven for RCC5 and RCC8 that path consistent constraint network over a distributive subalgebra is alway...

This study investigates the extent to which a localist-distributive hybrid formal model of human memory replicates observed behavioral patterns in perception and recognition of appropriately coded language data. Extending previous research that considered for modeled memorization only items with uniform, undefined randomly generated featural specifications, a MINERVA2 simulation was trained to ...

magnetotelluric (mt) method is an important passive surface geophysical method which uses the earth’s natural electromagnetic fields to investigate the electrical resistivity structure of the subsurface. the depth of investigation of mt is much higher than that of other electromagnetic (em) methods (vozoff, 1991). for a general conductivity distribution in the earth, the horizontal electric fie...

The problem of designing good Space-Time Block Codes (STBCs) with low maximum-likelihood (ML) decoding complexity has gathered much attention in the literature. All the known low ML decoding complexity techniques utilize the same approach of exploiting either the multigroup decodable or the fast-decodable (conditionally multigroup decodable) structure of a code. We refer to this well known tech...

The prefix pohas been productive to varying degrees in the derivation of a special class of distributive verbs in almost all the Slavic languages (the only exception being Sorbian; cf. Schuster-‹ewc 1968). Distributives in poare particularly common in Serbian (Sb) and Croatian (Cr); they are frequently encountered in all stylistic registers—colloquial speech as well as the press and belles lett...

We consider the problem of resource sharing when processing large numbers of continuous queries. We specifically address sliding-window aggregates over data streams, an important class of continuous operators for which sharing has not been addressed. We present a suite of sharing techniques that cover a wide range of possible scenarios: different classes of aggregation functions (algebraic, dis...
