The aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. Two types of sandwich composites with E-glass/Kevlar/polyester resin facings and End-grain balsa wood as core have been produced by vacuum infusion processing (VIP) and hand-lay up (HL) method. Compression tests on...

Large sandwich radomes are widely used for radar antennas because of the desired some characteristics. They are constructed by connecting small panels for the restrictions on manufacture. These connection parts yield undesired scattered waves and generate higher sidelobes. We present a novel method to overcome this problem by optimizing the radome geometric design. The scattering characteristic...

We exemplify an optimisation criteria for divide-and-conquer algorithms with a technique called generic competitive graph search. The technique is then applied to solve two problems arising from biocomputing, so-called Common Connected Components and Cograph Sandwich. The first problem can be defined as follows: given two graphs on the same set of n vertices, find the coarsest partition of the ...

Introduction: It is estimated that one-third of the world’s population is infected with M. tuberculosis. Also we came to know that the numbers of TB cases are on the rise in our rural based tertiary care hospital. We searched for Mycobacterium tuberculosis antigen in the serum of patients with pulmonary TB by developing Sandwich ELISA. Materials & Methods: We took 50 pulmonary TB patients, 50 d...
