Darwin-FIRST, is an Artificial Intelligence procedure to automatically retrieve intelligence diluted in huge databases. FIRST stands for Full Information Retrieval System on Thesaurus, one expert system aided by agents and Darwin stands for Distributed Agents to Retrieve the Web Intelligence, a network of FIRST nodes. FIRST algorithms and agents extract from databases their inherent intelligent...

G(u,u',u") = 0, (1) where u = u(x, x,..., x), and u', u" denote all the first and second partial derivatives of u. For simplicity we will assume here that both u and G are scalars and denote by ua, uab, the partial derivatives dau and respectively dahu; a,b =1,2, ..., n+1. Let u (x) be a given solution of (1). Our equation is said to be elliptic or hyperbolic at u°(x) according to whether the (...

We consider the problem of designing optimal linear codes (in terms of having the largest minimum distance) subject to a support constraint on the generator matrix. We show that the largest minimum distance can be achieved by a subcode of a Reed-Solomon code of small field size. As a by-product of this result, we settle the GM-MDS conjecture of Dau et. al. in the affirmative.

The present study aims to investigate language learners’ cognitive processes in on-line ESP courses. Three modes of inquiry are used: think-aloud protocol analysis, screen capture analysis, and correlation analysis. The theoretical foundations for the evaluation of the cognitive aspect of Ferdowsi Univeristy of Mashhad E-learning System are drawn from cognitive load theory, cognitive apprentice...

road traffic accident (rta) is a global burden of disease. more than 1.25 million people per year are killed by rtas. more than half of the fatalities strike vulnerable road users (e. g. pedestrians, skaters, cyclists and other non-protected road users). the ongoing challenge is to protect vulnerable road users (vru). as a vru is neither shielded by seatbelts or crumple zones nor by airbags, th...

these days, due to growing the e-commerce sites, access to information about items is easier than past. but because of huge amount of information, we need new filtering techniques to find interested information faster and more accurate. therefore recommender systems (rs) introduced for solving this problem. although several recommender approaches have proposed, collaborative filtering (cf) appr...

In this research various objective quality measures are evaluated in order to predict the intelligibility for a wide range of non-linearly processed speech signals and speech degraded by additive noise. The obtained results are compared with the prediction results of a more advanced perceptual-based model proposed by Dau et al. and an objective intelligibility measure, namely the coherence spee...
