Closest approach of a quantum projectile
Authors: Kumar A , Krisnanda T , Arumugam P , Paterek T 
Published: July 2021

Abstract
We consider the simplest case of Rutherford scattering, i.e. the head-on collision, where the projectile is treated quantum mechanically. The convexity of repulsive Coulomb force invokes a disagreement between the Ehrenfest’s and Hamilton’s dynamics. We show that the quantum projectile cannot approach as close as the corresponding classical one, and that the average distance of closest approach depends on the position spread of the wave function describing the projectile.

Dipole Moment Studies in some Substituted Anilines with Alcohols
Authors: Priscilla R. , Deepika A. , Ida Malarselvi R. 
Published: July 2021

Abstract
Dipole moments have been determined by using the mixtures of diluted solutions of aniline, o-chloro aniline, p-chloro aniline, ethanol, 2-butoxy ethanol and 2-methoxy ethanol in carbon tetrachloride at 30° C based on Debye’s polarization method and Huysken’s method. The results are interpreted that the complex dipole moment for the halogen substitution of acceptor complexes is greater than the mono substituted acceptor complexes. But the case is reversed in halogen substitution of donor complexes.

Reliability Analysis a Two-Unit Cold Redundant System Working in a Pharmaceutical Agency with Preventive Maintenance
Authors: Malhotra Reetu , Dureja Tanishq , Goyal Aashish 
Published: July 2021

Abstract
The present paper examines the working and reliability of a pair of a two-unit cold redundant system in a pharmaceutical agency. Initially, out of two units, one unit is operative and the other unit acts as a cold redundant. On the failure of the working unit, the redundant unit is put to work. As the demand varies, the manufacturing of the product is also very much affected and so the machines may need to put into the rest period when the vast range of manufacturing is in the distinction to those demanded. It leads to a decline in the warranty period of the product. Additionally, another factor of the preventive/corrective maintenance (PM/CM) is also taken into the consideration. The main aim is to an evaluation of the expected rest period and expected PM/CM period and to determine the maximum profit gained by the company using the Markov process and regenerative technique. The authors have calculated various measures of the system’s effectiveness. Numerical consequences and graphs of a precise case are additionally included.
Computational fluid dynamics modelling and experimental analysis of a Photovoltaic Thermal system with spiral absorber using hybrid TiO2 – MWCNT nanofluid
Authors: Sacithra A. , Gomathi S. , Manivannan A. 
Published: July 2021

Abstract
The temperature increase of the PV panel reduces the electrical efficiency of the module. In order to boost electrical efficiency, the temperature of the PV panel is decreased by working fluids such as water and water based TiO2-MWCNT hybrid nanofluid. The pattern of the absorber is spiral. The spiral flow absorber collector is a steady loop. This model was implemented to determine the total heat gain and total combined efficiency of the PV module. The findings show that total thermal performance, optimum thermal output and electrical performance achieved by TiO2 –MWCNT nanofluid is more compared with water. In the nanofluid coefficient of convective heat transfer is higher than that of the base liquid at the same mass flow rate. For a mass flow rate of 0.01 kg/sec, the maximum thermal efficiency and electrical efficiency obtained are 52.8 per cent and 8.6 per cent, respectively, relative to the simulation results.
Modular, Weakly distributive and Normal trellises
Authors: Rai Shashirekha B. , Rao Prashantha 
Published: July 2021

Abstract
Psosets and trellises are generalizations of posets and lattices respectively. In fact, these notions are introduced independently by E. Fried and H. L. Skala. It is well known that a graph can be used to describe a partial order. In this paper, the concepts of modular, weakly distributive and normal trellises are introduced. We have proved that a trellis satisfying sheering property is modular. It is also proved that every strongly connected trellis is nonmodular. It is shown that every separating element of a trellis is modular and every modular element is weakly separating. Well-known result of M.H. Stone namely “Every maximal ideal of a distributive lattice is prime” is generalized to trellises. It is proved that a relatively complemented trellis is a lattice if and only if it is normal.

Authors: Satish S , Mohan Kumar S 
Published: July 2021

Abstract
Two and Three chamber expansion muffler are commonly used in light category vehicle for meeting the noise level legislature requirement. The Helmholtz resonator and expansion chamber are used in exhaust muffler to attenuate the noise in low and middle frequency range. In this work, the effect of expansion chamber size on back pressure is determined using CFD and the same geometry were used to study the acoustic attenuation performance using FEA in the frequency range of 0 to 3000 Hz. Regarding the size of individual expansion chamber there is about 17% increase and decrease in size from base model geometry were considered for performance comparison in both two and three chamber type of muffler. It is found that minimum back pressure of about 241 Pa is observed for 2 chamber base model (2C-B) with slightly higher turbulent kinetic energy value of 77.53 J/Kg. The sound pressure level (SPL) at outlet pipe is less for 3 chamber mufflers and the obtained value is less than 120 dB for most of the frequency range of 0 Hz to 3000 Hz. Similarly transmission loss (TL) is higher for 3 chamber mufflers and the value remains same for 0 to 1600 Hz frequency range and peak fluctuation occurs at higher frequency. The obtained results shows that 3C-A model is having higher noise attenuation performance with back pressure value within acceptable limit.

Impact of Electro-Magnetohydrodynamic Nature on Dispersion of solute in the Peristaltic Mechanism
Authors: Ponalagusamy R. , Murugan D. 
Published: July 2021

Abstract
The present article deals with the dispersion of a solute in peristaltic system. This mathematical model provides the analytical solution of electro-magnetohydrodynamic flow of biofluids through a channel. Treating blood as a Jeffrey fluid and considering homogeneous chemical reaction, the closed form of solution of effective dispersion coefficient is obtained by using Taylor’s limiting condition and long wave length approximation. The impacts of physiological parameters such as the electro osmotic velocity, electro kinetic, Jeffrey fluid parameter and Hartmann number on the Peristaltic movement have been investigated. It is found that the average equivalent dispersion coefficient is reduced with respect to the enhancement of homogeneous chemical reaction parameter and Hartmann number. It is pertinent to point out here that the electro osmotic velocity and electro kinetic parameter help to enhance average equivalent dispersion coefficient in comparison with the absence of applied electric field. The present analytical study provides useful information to artificial bio-processors.

In the presence of Electrical Debye Layer (EDL), the Poisson Boltzmann equation for the electrical potential within the micro channel is considered. To evaluate the electrical potential, Debye-Huckel linearization is employed the governing equations are modeled and reduce by small Reynolds number and long wavelength approximation and solved the exact solution. The axial fluid velocity, temperature, pressure gradient, pressure rise and stream functions are discussed with the effects of pertinent parameters (Hartmann number, Phase angle, relaxation time parameter) through the graphs.

Authors: Gladia Vincy C , Mary Mejrullo Merlin M 
Published: July 2021

Abstract
Grains have enacted a supreme role in human history and grain agriculture. Cereal grains are the worlds most substantial origin of food energy. The loss of grains can occur in three stages which are Pre-harvest, harvest and Post-harvest stages. Post-harvest losses take place during the time of harvest and the stage of human consumption. The losses can occur at the process of transportation, processing, storage and also by insects attack. In many developing countries the post-harvest losses are normal. In grain storage, several methods are being used to detect insects. But methods which are efficient and also time saving are very much needed. So, researchers have advanced many detection techniques to find insects in the stored grains. The weighted correlation coefficient using entropy weights give more enlightenment to solve many prevailing problem in real life. The encouragement of this research work is to interpret the sellers perspectives of insect detection technique for stored grains.

Authors: Vinoth S. , Sivasamy R. , Sathiyanathan K. 
Published: July 2021

Abstract
In the present work, we attempt to analyze the discrete form of Leslie type predator-prey system with the extension of nonlinear type harvesting of predators. The proposed model is obtained with the help of theory of piecewise constant argument for differential equations. We give the local stability properties of all possible non-negative fixed points. Also, our study reveals that the discrete system admits two bifurcations which are flip and Neimark-Sacker by making the use of center manifold argument and bifurcation theory, where the harvesting parameter is varied in order to take place of such bifurcations. Some simulations are carried out to depicts the obtained analytical results such as bifurcation plots and phase portraits. Also, it can be confirmed from numerical simulations that the considered system exhibits chaotic behavior for smaller values of harvesting parameter and becomes stable for larger values of same parameter. The largest Lyapunov exponents are plotted to show the sensitivity of chaotic regime.

The nonlinear evolution equations of fourth-order for two surface gravity waves including the effect of air flowing over water
Authors: Dhar A.K. , Manna Shibam 
Published: July 2021

Abstract
The nonlinear evolution equations of fourth-order have been established for two surface gravity waves in infinite depth of water including the effect of air flowing over water. In the present paper, we have applied a general approach depending upon the integral equation due to Zakharov. Based on these equations, the stability analysis has been studied in the appearance of a uniform gravity wave packet with another wave packet of the identical group velocity. Graphs have been drawn for the instability growth rate of the uniform wave packet with shorter wave number versus the perturbed wave number for several values of the amplitude of the wave packet of larger wave-number and several values of wind velocity. We have observed from the figures that the instability growth rate of the second wave packet enhances with the enhancement of nondimensional wind velocity for the settled value of the amplitude of the first wave packet.
