Abstract:

Three different techniques were assessed for estimation of chlorophyll content from each leaf samples. In the first method SPAD-502 hand held meter was used to estimate SPAD values of leaf. In the second method flatbed scanner was used to acquire the sample leaf image for estimation of SPAD and Chlorophyll concentration. The third method was biochemical based spectrophotometric approach for estimating chlorophyll concentration.Extensive statistical analysis based on Information criterion theory was made for selection and evaluation of proposed RGB image processing based color model for estimating SPAD value and chlorophyll concentration. The resultsrevealed that image processing techniques has good potential in estimating SPAD and chlorophyll concentration values relative to biochemical method using spectroscopic technique and SPAD meter reading. The present study also pointed out the fact that for the SPAD value and chlorophyll concentration estimation using proposed image processing technique gives better results with dual color band as compared to single or triple color band.Furthermore, estimated SPAD value and chlorophyll concentration differ from Image processing technique (photometric) measurement of leaf samples by 5.538% (p<0.001) and 0.0185% (p<0.001), respectively.

Abstract:

Thespace time fractional modified KdV equation and fractional Kolmogorov-Petrovskii-Piskunov(KPP)equation models the unidirectional and bidirectional waves on shallow water surfaces, long internal wavein a density-stratified ocean, ion acoustic waves in plasma, acoustic waves on a crystal lattice. The fractional derivatives are defined in the modified Riemann-Liouville sense.In this article, we obtain exact solution of these equations by means of the recently established two variables(G1/G,1/G)-expansion method.The solutions are

obtained in the form of hyperbolic, trigonometric and rational functions involving parameters. When the parameters are assigned particular values, the solitary wave solutions are generated from the traveling wave solutions. The method indicates that it is easy to implement,computationally attractive and is the general form of theoriginal(G1/G)-expansion method.

Abstract:

The communication in a clustered WBAN is performed at different levels through multiple nodes and controllers. This kind of multi-level involvement of nodes opens the nodes for security leaks. In this paper, a dual level security is integrated using hybrid cryptography method. A hybrid authentication and cryptography based method is defined for identity and information level security. The hybridization of security for clustered WBAN is achieved using RSA and hash key encoder. The RSA is here applied for node to controller for identification and verification whereas SHA is applied for reliable symmetric message encoding for node-to-controller and controller-to-controller communication. The proposed security model is applied in an integrated form to the clustered WBAN network to improve communication reliability. The proposed secure communication model has improved the performance of the network. The simulation is applied on clustered WBANs with different number of WBANs. The comparative simulation results show that the proposed model has effectively improved the packet communication and network life.

Abstract:

A big threat for the survival of mankind is the scarcity of power which is a serious matter to look into. Under this hard situation, the bioelectric energy is the most useful energy source instead of all the electronic power sources. Any electronic gadget can be activated with the help of bio-charger which is simple, portable and very much needed for the athletics. By recycling of energy and utilizing the energy conservation rule many problems related to energy consumption can be solved. The purpose of the research work is to make a bio-charger to preserve the bioelectric energy and to use it as the power source for any portable electronic gadget.

Abstract:

An automated hybrid model, called the Plant Neural System Model (PNSM), is introduced in this approach. Plants can process biochemical signals throughcertain biological processes even they don’t have brains. Important biological processes, like seed germination, root growth, and nutrient absorption by the cell are considered as these are the foundations of neuron systems in plants. Neurobiological processes have been adapted to develop a hybrid black box model with time-dependent functions like Artificial Neural Network (ANN) and the use of some advanced optimization techniques. This model would be useful in the analysis of soil parametric relations with both seed germination and seed optimization in order to classify plant seeds.

Computational Modeling of Boundary-Layer Flow of a Nanofluid Past a Nonlinearly Stretching Sheet

Authors:

A Mitra,

DOI NO:

https://doi.org/10.26782/jmcms.2018.04.00007

Abstract:

In the present investigation, steady two dimensional laminar natural convection flow resulting from non-linear stretching of a flat horizontal plate ina nanofluid is studied numerically. Boungiorno model [I] is employed that treats the nanofluid as a two-component mixture (base fluid plus nanoparticles), incorporating the effects of Brownian motion and thermophoresis.By appropriate similarity variables, the governing nonlinear partial differential equations of flow are transformed to a set of nonlinear ordinary differential equations. Subsequently they are reduced to a first order system and integrated using Newton Raphson and adaptive Runge-Kutta methods. The computer codes are developed for this numerical analysis in Matlab environment. Dimensionless stream function (s), longitudinal velocity (s′), temperature (θ) and nanoparticle volume fraction (f) are computed and illustrated graphically for various values of four dimensionless parameters, namely, Lewis number (Le), stretching parameter (n), Brownian motion Parameter (Nb), and thermophoresis parameter (Nt). The effects of the physical parameters on the rate of heat transfer(-θ́(0)) and mass transfer (-φ́(0)) is given in tabulated form.The results of the present simulation are in with good agreement with the previous reports available in literature.

Abstract:

Patch miniaturization is an ongoing trend in modern communication technology nowadays. In this paper functional behavior of E slotted patch is presented. With additional ground irregularities multi resonating frequency response is attained at range of 1-8GHZ resulting at most gain of 3.43dB -4.71dB, directivity in 3.68dBi-5.66dBi range with good impedance bandwidth. With use of fractal patch technique FR4 is chosen as substrate bases. With help of implementing shortening pin technique reduction of antenna is accomplished to 60.60%. By changing location of shortening pin only different desired bands resonation can be achieved. This type of microstrip antenna has applications in mobile phone for, S-Band and C-Band applications

Abstract:

Abstract
We have commenced an in-depth study through modeling and simulation to
investigate the performance of a CdTe solar cell at different Schottky barrier heights
for different combinations thicknesses of BSF as well as window layer and front
contact oxide layer (TCO) .The inter relation between BSF layer and back contact
schottky barrier height has been focused. Effect of the BSF layer regarding the
tunneling of charges has been investigated. In the present paper, we achieved in our
study the highest ƞ of 18.39%, Voc of 0.591 volt, Isc of 0.411 amp for 0.1 µm absorber
and 1nm BSF layer thickness in presence of higher schottky barrier (0.6eV) with
higher doping concentration of absorber layer. Thinning of the layers have always
been better in terms of performance and cost. But it brings pinhole formation
problems what we excluded here in our present work.
