Comparison between Rayleigh and Mie Scattering Assumptions for Z-R Relation and Rainfall Rate Estimation with TRMM/PR Data

Author 1: Kohei Arai

Comparison of the rain rate estimated with the assumptions of Rayleigh and Mie scattering is made. We analyzed the different relationships between the radar reflective factor and rain rate (so-called Z-R relationship) with both scattering models for different DSD (droplet size distribution) and rainfall types as the wavelength is 2.2cm… Read full abstract & cite →

Memetic Algorithm with Filtering Scheme for the Minimum Weighted Edge Dominating Set Problem

Author 1: Abdel Rahman Hedar Author 2: Shada N. Abdel-Aziz Author 3: Adel A. Sewisy

The minimum weighted edge dominating set problem (MWEDS) generalizes both the weighted vertex cover problem and the problem of covering the edges of graph by a minimum cost set of both vertices and edges. In this paper, we propose a meta-heuristic approach based on genetic algorithm and local search to… Read full abstract & cite →
