Reaction-diffusion equations are vitally important due to their role in developing sturdy models in various scientific fields. In the present work, we address an algorithm of the Daftardar-Gejji and Jafari method for solving the nonlinear functional equations of the form ψ = f +L(ψ) + N(ψ). Further, we employ this algorithm to solve Caputo derivative-based time-fractional Cauchy reaction-diffusion...
The research presents a modern way of bi-wheels differential mode odometry to predict the next planar and angular co-ordinate of mobile robots. The presented odometry incorporates two independent wheels with respective encoders. The rotation of two wheels is independent, and the change is determined by the difference in the velocity of the bi-wheels. Rotational velocities by the two wheels are determined...
Reversible watermarking is quite effective in transfer of small data through the medium of images and both could be easily recovered at the receiving end. Because of this it's widely used in medical imagery. Here we propose a technique based on difference expansion, in which the transferred image consist of the original image embedded with, the patient information, hash of the original image and the...
The Cherenkov excitation of THz radiation by periodic succession of electron bunches in a dielectric lined resonator is investigated. A TM mode of the resonator, that comprises forward and backward moving slow waves, is resonantly excited by the electron bunches when the bunches are in near phase synchronism with the forward wave. The THz wave amplitude rises with successive bunches. Each drive bunch...
Magnetic Levitation System (MLS) is a typical multi-variable, nonlinear and unstable system. The basic aim of our research work is for suspending the steel ball without any mechanical support in desired position with help of an efficient controller. The simulation of MLS based on its mathematical model is carried out in MATLAB and its real time implementation is also achieved. In this paper an interval...
Designing an efficient micro-mobility scheme for network mobility (NEMO) is an important issue. The Micro-NEMO is a well known protocol for micro mobility in NEMO. It has significantly lower signaling overhead and handoff latency. But, it suffers from single point failure problem. In this paper, we propose micro-NEMO++, an extension of micro-NEMO protocol, to eliminate the single point failure problem...
In this paper, a modified VLSI architecture for two-dimensional Radon Transform has been presented. The proposed architecture is primarily based on the analytical relationship between the pixels on horizontal and vertical raster scan line and also between the projection angles. The proposed architecture is compared against the existing ‘Parallel Pipeline Projection Engine’ (PPPE) architecture. Implementation...
