In two-dimensional space, we investigate the slow dynamics of multiple localized spots with oscillatory tails in a specific three-component reaction-diffusion system, whose key feature is that attract or repel each other alternatively according to their mutual distances, leading rather complex patterns. One fundamental pattern ring pattern, consisting $N$ equally distributed on circle certain r...

in this paper we have proposed an approach for emotion detection in implicit texts. we have introduced a combinational system based on three subsystems. each one analyzes input data from a different aspect and produces an emotion label as output. the first subsystem is a machine learning method. the second one is a statistical approach based on vector space model (vsm) and the last one is a key...

Component-oriented programming promises to provide many of the bene ts that object-oriented programming has arguably failed to deliver: increased productivity, reliability, and exibility via increased reuse of third-party software. Unfortunately, it is not always clear how componentoriented programming di ers from object-oriented programming, or why component-oriented programming should succeed...

the present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. the behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. boundedness and dissipativeness of the system are e...

university course timetabling problem is a serious challenge for the academic managers in each semester. because of a vast number of constraints and the complexity of relationship among the constraints, the problem is known to be of hard class. in this paper, a decision support system is proposed to assist the decision makers in solving the university course timetabling. the proposed system pro...
