VHDL Implementation of DIT-FFT using CORDIC

ABSTRACT Evaluating trigonometric functions, used in Digital Signal Processing applications like Discrete Fourier Transform (DFT), Discrete Hartley Transform (DHT) is a complicated task involving large area, high complexity and time issues. To reduce the delay at the expense of area constraints an optimized hardware efficient technique called Coordinate Rotation Digital Computer (CORDIC) is used. CORDIC […]

Design and Analysis of ANFIS Controller to Control Modulation Index of VSI Connected to PV Array

ABSTRACT This paper analyses the operation of an adaptive neuro-fuzzy inference system (ANFIS)-based maximum power point tracking (MPPT) for solar photovoltaic (SPV) energy generation system. The MPPT works on the principle of adjusting the voltage of the PV modules by changing the duty ratio of the Voltage source inverter. The duty ratio of the inverter […]

Effect of Heat aging on Mechanical Performance of MMT Clay Reinforced Thermoplastic Polyurethane (TPU)/EPDM Rubber Blends based Nano Composite

ABSTRACT The high temperature resistant polymer-nanocomposite was prepared using montmorillonite nanoclay as reinforcing fillers in polyester-based thermoplastic polyurethane/EPDM blends and the effect of increasing nanoclay loadings on physico-mechanical properties like hardness, tensile strength, modulus and Elongation at break was studied. Changes in mechanical and physical properties of polyurethane thermoplastic during aging at 70°C for 168 […]

Characteristic Polynomial for Detecting Isomorphism among 12-Link, 1-Freedom Simple Jointed Kinematic Chains (SJKCs)

ABSTRACT In this paper the complete collection of 12 link, 1-degree of freedom category of simple jointed kinematic chains (SJKCs) consisting of 6856 distinct chains are studied with an attempt to assess the efficacy of the characteristic polynomial based approaches using the link-adjacency, degree and structural matrix representations of kinematic chains for the detection of […]
