TL;DR: The proposed algorithm is named as fitness based particle swarm optimization (FPSO) and it is compared with standard PSO 2011 and ABC algorithm over 15 well known benchmark problems and three real world engineering optimization problems.
Abstract: Particle swarm optimization (PSO) is a popular population based approach used to solve nonlinear and complex optimization problems. It is simple to implement and swarm based probabilistic algorithm but, it also has drawbacks like it easily falls into local optima and suffers from slow convergence in the later stages. In order to reduce the chance of stagnation, while improving the convergence speed, a new position updating phase is incorporated with PSO, namely fitness based position updating in PSO. The proposed phase is inspired from the onlooker bee phase of Artificial Bee Colony (ABC) algorithm. In the proposed position updating phase, solutions update their positions based on probability which is a function of fitness. This strategy provides more position updating chances to the better solutions in the solution search process. The proposed algorithm is named as fitness based particle swarm optimization (FPSO). To show the efficiency of FPSO, it is compared with standard PSO 2011 and ABC algorithm over 15 well known benchmark problems and three real world engineering optimization problems.

TL;DR: The proposed design is a rectangular patch antenna with slots at the centre frequency 10 GHz that can be reconfigured in the frequency range of 10–10.5 GHz and the simulated are very exciting and show the close agreement with proposed design.
Abstract: Recent developments in the wireless communication industry continue to drive the requirements for small, compatible, and affordable reconfigurable antennas. To overcome the challenges of multi-frequency operation a new scheme of frequency reconfiguration is proposed. In the proposed design a rectangular patch antenna with slots at the centre frequency 10 GHz that can be reconfigured in the frequency range of 10–10.5 GHz. The reconfiguration is carried out by switching the diodes ON/OFF. The antenna is designed on FR4 substrate (e r = 4.54) of thickness (H) 1.50 mm. The proposed structure was simulated by using the electromagnetic (EM) simulation software. The simulated return loss for different configuration are less than −10dB at resonance frequencies. The simulated are very exciting and show the close agreement with proposed design.

TL;DR: In this article, the modal characteristics of FGM annular plate under hygrothermal effect were investigated by using the MUMPS eigen solver to obtain the eigenfrequencies and corresponding mode shapes.
Abstract: This paper investigates modal characteristics of FGM annular plate under hygrothermal effect. The mechanical properties are supposed to have a continuous variation along the thickness of the plate. The power law or sigmoid law functions are used to govern the resultant mechanical properties. The MUMPS eigen solver which is exists in COMSOL Multiphysics® (version 5.2) software is employed to obtain the eigenfrequencies and corresponding mode shapes. The accuracy of the method is validated by comparing the results with the results published work for particular case. Effects of functionally graded index, radius- to-thickness ratio, and temperature and moisture changes on the natural frequencies are discussed in detail. An excessive stress due to drastic moisture and temperature gradients make the engineering structures susceptible to failure. Due to the fact that, continuously identified natural frequencies of vibration under temperature and moisture effect can provide unique information during both initial fabrication and service life of different mechanical structures. Hence, this study can be helpful directly or indirectly in development of highly efficient environmental sensors that are very necessary in a structural health monitoring perspective. It can be observed that the fundamental frequency decreases with increase in functionally graded index and the moisture content rise under the power law model whereas under sigmoid law model the frequencies remain almost constant with increase in functionally graded index.
