The research presents recurrent wavelet based adaptive control (RWNC) scheme for uncertain nonlinearity based delayed systems with hysteresis. For the estimation of uncertainties present in the system and hysteresis nonlinearity effect used Self recurrent wavelet neural network (SRWNN). Deployment of hysteresis phenomenon in proposed work used Prandtl-Ishlinskii (PI) model. Proposed Controller consists of wavelet based feedback system and a robust control mechanism. The simulation study carried out for stability analysis of the proposed controller using Lyapunov-Krasovskii function and verifies the effectiveness of theoretical development. © Research India Publications.

1, 2, 4, 8,16,32,64, 128 channel UP convertor implemented in GSM has been designed and developed in this paper. The convertor is implemented using CM FIR filter requiring less routing area, less static and dynamic power and finally, providing high sampling rate conversion with large bandwidth. The system developed is superior to direct form based down convertor in terms of high power consumption, large delay& limited channels up to 128 channels. We have achieved large sampling rate conversion with large bandwidth & low power consumption using combination of CIC & MAC architecture of FIR filter. The 8 channel model consumes 3231.7mw (static power 3055.1mw & dynamic 176.6mw). After applying three different routing & placement algorithms on 8 channels model namely global routing, channel routing and river routing the power consumed results 2744.1mw (static power 2612 mw & dynamic 132.1mw), 193.7mw (static power 71.4mw & dynamic 122.3mw) and 189..6mw (static power 67.6mw & dynamic 122 mw) respectively. In an extended work the authors have tried and successfully executed the model and system for 128 channels for 4G applications. The proposed model is first designed on simulink platform using Xilinx blackest and then it is transferred on FPGA platform using system generator. The complete circuit is synthesized, implemented, simulated using Xilinx design suite. © 2014 IEEE. Source

The present study revealed the performance of subsurface drainage systems for long-term sustainability of irrigated agriculture. The performance of subsurface drainage systems was evaluated on the basis of drain spacing equations for disposal of effluent and hydraulic characteristics of envelop materials, like entrance resistance created by envelop and hydraulic conductivity. Three important synthetic envelopes, HG 22, SAPP 240 and CAN 2 were tested in laboratory using sand tank model and permeability apparatus to compare their performances in terms of entrance resistance and hydraulic conductivity of soil envelope system. The hydraulic conductivity for SAPP 240 filter was found the highest and entrance resistance the lowest. Performance of four unsteady state drain spacing equations viz. Glover-Dumm, Van Schilfgaarde, Integrated Hooghoudt and Modified Glover equations were also tested to evaluate disposal efficiency of excess water. The percentage deviation between predicted drain spacing and actual spacing was -33.31% to -31.55%, 9.40% to 17.07%, 11.84% to 20.83% and 6.10% to 14.62% for Glover-Dumm, Van Schilfgaarde, Integrated Hooghoudt and Modified Glover equations, respectively. Modified Glover equation showed minimum deviation from actual drain spacing due to its versatile applicability. Therefore, the Modified Glover equation with SAPP 240 filter was recommended for subsurface drainage system in sandy soil texture areas. Source

In this paper, we have designed a Reconfigurable Digital Sequential System on Chip design capable of transmitting and receiving data in parallel in 8 bits to 512 bits range. This circuit provides Reconfigurable point to point communication, data rate of 1.54 Gbits/sec to 277 Gbits/sec. The design comprises of two Sub Circuits: Transmitter/Receiver & Router. Our objective after developing Reconfigurable system was reduction of the power consumption in the circuit by exploiting Dynamic Partial Reconfiguration, which we get after results is nearly 5% - 10% of the total power consumption of the circuit and finally we have concluded the calculated parameters i.e. Power Consumption (Static and Dynamic), Delay, data rate and Resources Utilized by taking all the Reconfigurable Transreciever as platform on the various FPGA families by Xilinx and finally plot them on graph, so as to exploit respective family according to application, specification as well as constraints what is the best chosen parameter and family according to the analysis made. The complete circuit is programmed in VHDL, and synthesized and simulated on Xilinx design suite 14.4 ISE. © 2013 IEEE. Source

Availability of natural sand conforming to required standards for use in concrete is diminishing day by day and is severely affecting the construction industry. On the other hand, disposal of used rubber tyres is an environmental, health and esthetic problem as its recycling is extremely difficult. In this paper, a systematic experimental investigation is carried out on concrete with rubber fibers (obtained by grinding waste rubber tyres) as partial replacement of fine aggregates, to evaluate the compressive strength, density, water permeability, static modulus of elasticity, dynamic modulus of elasticity and chloride diffusion. Rubber fibers have been used with three different water-cement ratios (0.35, 0.45 and 0.55). Six levels of rubber fibers contents (0, 5, 10, 15, 20 and 25%) as partial replacement of sand and three levels of silica fume (0, 5 and 10%) as partial replacement of cement have been considered. Microstructure analysis of rubber fiber sample by scanning electron microscope and Energy dispersive X-ray analyzer has been carried out. Compressive strength, static and dynamic modulus of elasticity of waste rubber tyre fiber concrete are found to decrease with the increase in the replacement level of fine aggregates by rubber fibers. © 2015 Elsevier Ltd.
