douala metropolitan city loated in the littoral province of cameroon,has experienced a rapid urbaniation and industralisation. the city depends heavily on groundwater as a resource. due to ubiquitous sources of pollution, groundwater quality and contamination has become an imprtant issue for this urban groundwater supply. this study uses the major ion chemistry of groundwater together with t...

well exposed famennian, mainly carbonate rocks of the bahram formation in the vicinity of bagher abad village, central iran,yielded chondrichthyan teeth some sarcopterygii and actinopterygii teeth and fragments. three different genera were recognizedamong the chondrichthyan teeth represented by: phoebodus turnerae, ph. spp., deihim mansureae (m2, m3), stethacanthus sp..acanthodian and sarcopter...

naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. the main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. in t...

The BI ( 比 )-structure, which highlights a contrasting characteristic between two items, is the key comparative sentence structure in Chinese. In this paper, we explore the methods of extracting the 6 constituents of the BI-structure. Previous studies are often restricted to probabilistic classification methods, where the feature used hardly embodies linguistic knowledge, therefore unintuitive....

This paper describes UAIC’s Question Answering systems participating in the ResPubliQA 2010 competition, designed to answer questions on a juridical corpora in Romanian, English and French monolingual tasks. Our systems adhere to the classical architecture of a Question Answering system, with an emphasis on simplicity and real time answers: only shallow parsing was used for question processing,...

This paper focuses on the automated extraction of concrete entities from a specialized-domain corpus. Then, in a bootstrapping phase, the candidates are used to extract new candidates. Concrete entities are automatically identified by a set of spatial features. In a spatial scene something is located by virtue of the spatial properties associated with a reference object. The axial properties ar...

The study of extraordinary performance has been carried out almost independently in two research traditions, the first emphasising practice and the second emphasising talent. The practice tradition has collected empirical evidence strongly supporting chunking as a key learning mechanism and practice as a prerequisite for becoming an expert. The talent tradition has provided convincing data for ...

This paper introduces a new approach to morpho-syntactic analysis through Humor 99 (High-speed Unification Mo.rphology), a reversible and unification-based morphological analyzer which has already been integrated with a variety of industrial applications. Humor 99 successfully copes with problems of agglutinative (e.g. Hungarian, Turkish, Estonian) and other (highly) inflectional languages (e.g...

We show that uniication in certain extensions of shallow equational theories is decidable. Our extensions generalize the known classes of shallow or standard equational theories. In order to prove de-cidability of uniication in the extensions, a class of Horn clause sets called sorted shallow equational theories is introduced. This class is a natural extension of tree automata with equality con...
