In several critical military missions, more than one decision level are involved. These decision levels are often independent and distributed, and sensitive pieces of information making up the military mission must be kept hidden from one level to another even if all of the decision levels cooperate to accomplish the same task. Usually, a mission is negotiated through insecure networks such as the...
In this paper, we implement hybrid Woodward-Lawson Neural Networks and weighted Fourier method to synthesize antenna arrays. The neural networks (NN) is applied here to simplify the modeling of MIMO antenna arrays by assessing phases. The main problem is obviously to find optimal weights of the linear antenna array elements giving radiation pattern with minimum sidelobe level (SLL) and hence ameliorating...
In this paper, we study an electromagnetic optimization technique using Taguchi's method and apply it to circular antenna array (CAA) design. Taguchi's method was developed on the basis of the orthogonal array (OA) concept, which offers systematic and efficient characteristics. The newly proposed idea is the implementation of Taguchi optimization method for CAA of order 10, 16 and 24 respectively...
The paper focuses on the conceptual development of an innovative method for authenticating sensors connected using Modbus TCP. Modbus TCP is a highly used industrial networking protocol that has very good performances but lacks security. In the first section of the paper, the authors try to highlight the importance of security of industrial control systems. The second section is dedicated to presenting...
In this paper, we study an electromagnetic optimization technique using Taguchi's method and apply it to concentric ring antenna array design. Taguchi's method was developped on the basis of the orthogonal array (OA) concept, which offers systematic and efficient characteristics. The newly proposed idea is the implementation of Taguchi optimization method for Concentric Circular Antenna Array (CCAA)...
Multiple-input multiple-output (MIMO) systems are commonly used in wireless communications to ensure high bit-rate and high capacity transmission. Space time block coding (STBC) is a technique used in MIMO to provide transmit diversity in communication over fading channels. Although STBC has full diversity gain, the coding gain need to be improved by using channel coding such as low density parity...
