Combinatorics of generalized Tchebycheff polynomials

By considering a family of orthogonal polynomials generalizing the Tchebycheff polynomials of the second kind we refine the corresponding results of De Sainte-Catherine and Viennot on Tchebycheff polynomials of the second kind (Lecture Notes in Mathematics, vol. 1171, 1985, Springer-Verlag, 120). © 2003 Elsevier Science Ltd.

Route Planning Made Easy - An Automated System for Sri Lanka

Commercial cities like Colombo constantly face to problem of traffic congestion due to the large number of people visiting the city for various reasons. Also these cities have a large number of roads with many roads connecting any two selected locations. Finding the best path between two locations in Colombo city is not a trivial task, due to the complexity of the road network and other reasons...

A Conic Programming Approach to Generalized Tchebycheff Inequalities

Consider the problem of finding optimal bounds on the expected value of piece-wise polynomials over all measures with a given set of moments. This is a special class ofGeneralized Tchebycheff Inequalities in probability theory. We study this problem within the framework of conic programming. Relying on a general approximation scheme for conic programming, we show that these bounds can be numeri...

Poster B1 Laser Ablation: an Easy Route to Obtain Gold and Silver Nanomaterials

Needle-like ZnO nanostructures were synthesized by an organic-free hydrothermal process. Thehydrothermal synthesis was performed at very low pressure (~20 kPa) with duration of process only 10min. The products were characterized by X-ray powder diffraction (XRD)and transmission electronmicroscopy (TEM).The XRD pattern indicated that the needle –like ZnO nanostructures were hexag...
