Topological derivatives for networks of elastic strings

QSPR study on benzene derivatives to some physico-chemical properties by using topological indices

QSPR study on benzene derivatives have been made using recently introduced topological methodology. In this study the relationship between the Randic' (x'), Balaban (J), Szeged (Sz),Harary (H), Wiener (W), HyperWiener and Wiener Polarity (WP) to the thermal energy (Eth), heat capacity (CV) and entropy (S) of benzene derivatives is represented. Physicochemical properties are taken from the quant...

The use of topological indices to predict thermodynamic properties of amino acids derivatives

In the present investigation the applicability of various topological indices are tested for the QSPR study on 80 amino acids derivatives. Relationship between the Randic' (1X), Balaban (J), Szeged (Sz), Harary (H), Wiener (W), Hyper-Wiener (WW) and Wiener Polarity (WP) indices to the thermodynamic Properties such as thermal energy Eth (J/mol) and heat capacity (CV J/mol. K) of amino acids is r...

Topological Derivatives in Plane Elasticity

We present a method for construction of the topological derivatives in plane elasticity. It is assumed that a hole is created in the subdomain of the elastic body which is filled out with isotropic material. The asymptotic analysis of elliptic boundary value problems in singularly perturbed geometrical domains is used in order to derive the asymptotics of the shape functionals depending on the ...

Application of topological and physicochemical descriptors: QSTR analysis of the toxicity of benzene derivatives

A Differentiated Pricing Framework for Improving the Performance of the Elastic Traffics in Data Networks

Rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. Most commonly used algorithm in end hosts is TCP. This is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. Moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by TCP affect other sessions...
