Anti-synchronization of Bhalekar–Gejji Chaotic System via Nonlinear Active Control
Abstract: AbstractIn this paper, a scheme of global anti-synchronization between two identical newly developed Bhalekar–Gejji chaotic system is proposed. This anti-synchronization scheme is achieved by using nonlinear active control since the parameters of both the systems are known and states are measurable. Lyapunov stability theory is used to ensure stability of error dynamics. Controller is designed by using the sum of relevant variables in master and slave chaotic systems. Simulation results …

Studies on Effect of Varying Geometric Parameters of Solar Receiver Tube on Thermal Loss Suffered By It
Abstract: AbstractThe radiative and convective heat losses from a solar receiver tube at a given operating temperature are a function of temperature of the outer glass envelope and outer surface area of the glass envelope. But the temperature of the outer glass envelope and its outer surface area are themselves a function of outer diameter of the heat pipe enclosed within the glass envelope and the annular gap between the outer …

Photo-degradation in Nanocrystalline Porous Silicon
Abstract: AbstractWe study the metastabilities created by light soaking (LS) in nanocrystalline porous silicon (nc-PSi), prepared by the electrochemical anodization technique. At first sight, these appear similar to the effects of LS observed in hydrogenated amorphous silicon (a-Si:H) prepared by PECVD (Plasma-enhanced chemical vapor deposition) method. In nc-PSi, the ESR (Electron Spin Resonance) and Raman results indicate the presence of a-Si:H. This suggests a-Si:H as a possible cause of photo-degradation in …

Fabrication and Parametric Analysis of Thermal Sensing Dielectric PZT Thick Film Nano Ceramic Device Developed by SOL GEL Technique
Abstract: AbstractExtensive investigation carried out during earlier half of twentieth century, prominently established that the ionic radius of an atom gets reduced to significant levels with decrease in coordination number. The findings of Goldsmith and Pauling showed that ionic radii contracts by 4, 6 and 12% when coordination number is reduced from 12 to 8, 6 and 4 respectively. It is obvious that coordination number reduction takes place at the surface …

Design and Control of Conveyors with Buffer System and Integrated Drilling using PLC
Abstract: AbstractConveyors are one of the most widely used means of moving the product almost everywhere. The result of design and control of conveyor with buffer system and integrated drilling system using PLC helps to solve the problem of overload of conveyor system and packaging unit, never effects the production and avoids the complete shutdown of the entire system. Conveyor system is designed such that the production rate has the maximum …
