In this work, we concentrate on the analysis of the time-fractional Rosenau–Hyman equation occurring in the formation of patterns in liquid drops via q-homotopy analysis transform technique and reduced differential transform approach. The q-homotopy analysis transform algorithm can provide rapid convergent series by choosing the appropriate values of auxiliary parameters ħ and n at large domain. The reduced differential transform technique gives wider applicability due to reduction in computations and makes the calculation much simpler and easier. The proposed techniques are realistic and free from any assumption and perturbation for solving the time-fractional Rosenau–Hyman equation. © 2017 The Natural Computing Applications Forum

In this paper, we constitute a homotopy algorithm basically extension of homotopy analysis method with Laplace transform, namely q-homotopy analysis transform method to solve time- and space-fractional coupled Burgers' equations. The suggested technique produces many more opportunities by appropriate selection of auxiliary parameters ℏ and n(n≥1) to solve strongly nonlinear differential equations. The proposed technique provides ℏ and n-curves, which describe that the convergence range is not a local point effects and finds elucidated series solution that makes it superior than HAM and other analytical techniques. © 2016 Faculty of Engineering, Alexandria University.

In this paper, two efficient analytic techniques namely the homotopy analysis transform method (HATM) and homotopy perturbation Sumudu transform method (HPSTM) are implemented to give a series solution of fractional convection-diffusion equation which describes the flow of heat. These proposed techniques introduce significance in the field over the existing techniques that make them computationally very attractive for applications. Numerical solutions clearly demonstrate the reliability and efficiency of HATM and HPSTM to solve strongly nonlinear fractional problems. © 2016 Faculty of Engineering, Ain Shams University.

This paper presents a design of triangular microstrip antenna with truncated tip and experimentally studied on Ansoft Designer v-2.2.0 software. This design technology is achieved by cutting all three tips of the triangular microstrip antenna and placing a single coaxial feed. Triangular patch antenna is designed on a FR4 substrate of thickness 1.6 mm and relative permittivity of 4.4 and mounted above the ground plane at a height of 6 mm. Bandwidth as high as 11.07% are achieved with stable pattern characteristics, such as gain and cross polarization, within its bandwidth. Impedance bandwidth, antenna gain and return loss are observed for the proposed antenna. Details of the measured and simulated results are presented and discussed. ©2010 IEEE.

Rh(I) complexes of S-triazines and azobenzene were found to be very efficient towards the catalytic hydrogenation of alkenes, alkynes at normal pressure, and at room temperature. Reduction of aromatic nitrocompounds, benzaldehyde, and benzil were observed in appreciable amounts only at high pressure and at high temperature. No diminished catalytic activity was observed even after 6-8 repeated catalytic runs. Profound effect was observed on the rate of reduction in presence of extra ligand without affecting the nature of yield, both under normal and high pressure conditions. Kinetics was studied. Mechanism has been proposed and rate equation has been derived. Copyright © Taylor & Francis Group, LLC.

Myth or Reality: Is Electromagnetic radiation in form of radio frequency (RF) coming from mobile towers which are well known as Base Trans-receiver Station (BTS) affect the human body parts or not. This document investigates about the amount of radiation emitted by BTS tower which is measured by Selective Radiation Meter (SRM-3006). After that these values are compared by the guidelines and limits that are to be set by International Commission on Non Ionized Radiation Protection (ICNIRP) for the exposure of non-ionized radiation in the form of electromagnetic field, power density or Specific Absorption Rate (SAR). This study also helps to estimate most affected part of human body by compare the values with the guidelines of general public exposure. © 2014 IEEE.

Rh(I) complexes of S-triazene were found moderately efficient towards the catalytic oxidation of internal alkenes, terminal alkenes, and alcohol in C2H5OH-CH2Cl2 (1:1) mixed solvent system both under normal and high pressure of molecular oxygen. No diminished catalytic activity was observed even after 6-8 repeated catalytic runs. Effect of extra ligand on the rate of oxidation, nature and percentage yield of products was investigated. On the basis of kinetics and other experimental observations, a reaction mechanism has also been proposed.

In this paper, a novel rectangular planar ultra-wide band antenna (UWB) with band-notched characteristics is presented. The proposed design has two level stepped corners (lower) at the radiating patch along with two inverted L shaped slots on the two non-radiating edges of the microstrip patch antenna. The dimensions of the two L slots are optimized so as to achieve the U-NII band rejection (5.15 GHz to 5.825 GHz). The proposed antenna is designed and simulated using Computer Simulation Technology Microwave Studio (CST-MWS). This antenna operates in a frequency band ranging from 2.79 to 11.03 GHz with a band rejection from 4.88 to 5.94 GHz. The dimension of the proposed design is 27.00 mm (L), 32.42 mm (W) and 1.7 mm (H). The VSWR is less than 2 for entire operating frequency range. The impedance bandwidth of the proposed design is nearly 7.18 GHz with band rejection. This antenna can be used in various applications in 3.5 GHz WiMAX, 4 GHz C band and lower frequencies of X band without interference from U-NII (Unlicensed National Information Infrastructure) band. The effect of the partial ground plane and the dimensions of stepped corners with two inverted L slots are optimized for better return loss, whose parametric study is discussed in detail. © 2015 IEEE.
