Culmination of the Quantum theory in Sri Aurobindo’s poetic consciousness

The Quantum theory visualizes that uncertainty is the ultimate truth behind the dualism of wave and particle at the sub-atomic plane of Matter. It does not find any physical law capable of explaining the physical state in which the conversion of wave into particle and vice-versa takes place at the sub-atomic plane of Matter. In fact, the conversion evades all the physical laws on account of which Werner Heisenberg...

Magnetic Field Effects on Entropy Generation in Heat and Mass Transfer in Porous Cavity

The entropy generation for natural convection heat and mass transfer in a two dimensional porous cavity subjected to a magnetic field is selected for numerical investigation. The Darcy model is used in the mathematical formulation of the fluid flow in porous media. The mathematical model is derived in dimensionless form and the governing equations are solved using the finite volume method. The governing parameters arise...

Applications of Schrödinger equation in general Besov spaces

In this paper, we obtain solution of Schrödinger equation in general Besov spaces. Precise results on  and general Besov estimates of the maximal function of the solutions to the Schrodinger equation are given. The obtained results improve some recent results. Further, we shall consider estimates of general -norm and the general Besov type norm of integrals of this kind by means of the...

Comparison study between differential transform method and Adomian decomposition method for some delay differential equations

A numerical method based on the differential transform method (DTM) and the Adomian decomposition method (ADM) is introduced in this paper for the approximate solution of delay differential equation (DDE). The algorithm is illustrated by studying an initial value problem. The results obtained are presented and show that only few terms are required to obtain an approximate solution which is found to be accurate and...

On the Fekete-Szegö like inequality for meromorphic functions with fixed Residue

In the present paper, we will consider the class of meromorphic starlike functions with fixed residue .   Silverman et al. (2008) has obtained sharp upper bounds for Fekete-Szegö like functional  for certain subclasses of meromorphic functions. In this paper, we will find sharp upper bounds for  for the class meromorphic starlike functions with fixed residue . The aim of the...

On three-dimensional quasi-Sasakian manifolds admitting semi-symmetric metric connection

The object of the present paper is to study three-dimensional quasi-Sasakian manifold equipped with semi-symmetric metric connection. The geometrical properties of conformal curvature tensor and the conservative quasi-conformal curvature tensor are discussed with such connection. Among other we have deal the conservative properties of quasi-conformal curvature with respect to semi-symmetric metric...

On enhanced control charting for process monitoring

The information on auxiliary characteristics helps significantly in increasing the efficiency of control charts for detecting shifts in process parameters. In this study we proposed Shewhart type control charts, namely the  chart, the  chart and the  chart, which utilizes information on two auxiliary characteristics (X and Z) for improved monitoring of process location parameter...

Frame structure for Mobile multi-hop relay (MMR) WiMAX networks

Mobile Multi-hop Relay (MMR) WiMAX network uses Relay stations (RSs) to extend the cell coverage, and enhances the link quality and the throughput. In MMR WiMAX networks, the number of hops between the Subscriber stations (SSs) and the Base station (BS) is allowed to be more than two hops when Non transparent RS (NT-RS) is used. However, this requires modification to the frame structure of NT-RS to reduce the delay of...

Mobile agent based clustering and maintenance using secure routing protocol for mobile ad hoc network

Routing in mobile ad hoc network is the challenging task due to the dynamic nature and resource limitations of network. Network clustering deals with partitioning network into clusters based on some rules. Clustering guarantees limited resource utilization and network scalability. In this paper, we mainly focused on using mobile agents for collecting information about cluster members and cluster maintenance. Ensuring...

Multi-band meta-material structures based on hexagonal shaped magnetic resonators

In this paper, we propose a new multi band meta-material structure composed of a unit cell that has multiple hexagonal-shaped metal rings printed one inside the other. The introduced meta-material composition exhibits multi-resonant behavior due to distinct magnetic resonances caused by the self and mutual coupling of each inclusion. The number of distinct magnetic resonances is determined...

A method of dual-process sample selection for feature selection on gene expression data

A method of dual-process sample selection based on support vector machine (SVM) is proposed to select informative features in this paper. Samples in a training set are used to train a SVM model, and the samples excluding support vector samples are chosen to select critical features in the procedure of recursive feature elimination (RFE). The effect of the dual-process sample selection method on feature selection is...

Mechanical properties of microwave sintered 8 mol% yttria stabilized zirconia

This paper reports the synthesis and characteristics of nano sized 8 mol% yttria stabilized zirconia (8YSZ). The nano sized 8YSZ powder (15 nm) has been prepared by the sol-gel technique. The phase formation was confirmed by the X-Ray Diffraction (XRD) analysis and the particle size verified by transmission electron microscope (TEM). The prepared 8YSZ green samples were sintered in a microwave furnace at 1500°C for...

Regional variation of columnar refractivity with meteorological variables from climate monitoring satellite application facility (CM SAF) data over Nigeria

Data from satellite application facility on climate monitoring (CM SAF) have been used to estimate and study seasonal variation of columnar refractivity in relation with relative humidity and temperature for twenty six stations categorized into four climatic regions (coastal, Guinea savannah, midland and sub Sahel regions) over Nigeria. Mean, standard error, maximum, minimum values and ranges of these...

Lead contamination of traditional hand-dug wells in parts of Kwale County, Kenya

People’s health, behavior and intellect to a certain extent are a function of their environment. One important component of this environment is water, a basic necessity that human beings cannot do without. The water available, however, is not always safe for human consumption due to contamination. Among the many water contaminants, lead (Pb) is one of the most dangerous due to its bio-accumulative nature and high...

Toxicity of arsenic (As) on seed germination of sunflower (Helianthus annuus L.)

The effect of different levels (2, 4, 6, 8 and 10 mg/L) of arsenic (as sodium arsenate and sodium arsenite) on germination percentage, mean germination time, days to 50% germination, plumule and radicle length and seedling vigour index of four sunflower cultivars (FH-331, FH-385, FH-405 and FH-415) was determined under laboratory conditions. Germination percentage was gradually decreased with the increase in arsenic...
