I propose the coefficient, t h , and its modification Nt which in a simple way reflect dynamics of scientific activity of an individual researcher. I determine t h as a time period (from some moment in the past till the present moment) during which papers responsible for 1/2 of the total citation index were published. Parameter Nt represents average of the citation index over this period: Nt = ...

We apply a method to filter relevant information from the correlation coefficient matrix by extracting a network of relevant interactions. This method succeeds to generate networks with the same hierarchical structure of the Minimum Spanning Tree but containing a larger amount of links resulting in a richer network topology allowing loops and cliques. In Tumminello et al., 1 we have shown that ...

Towards an Automated Optimization of Laminated Composite Structures: Hierarchical Zoning Approach with Exact Blending Rules

We present an automated methodology to optimize laminated composite structures. Our approach, inspired by bi-level optimization scheme, avoids its prime deficiencies and is based on developed computationally inexpensive stacking sequences reconstruction algorithm, which identically satisfies conventional set of blending rules. We combine it with proposed tight approximation to feasible domain o...
