In a complex valued neural network (CVNN) the weights, threshold, inputs and outputs are all complex numbers. Researchers have proposed many complex activation functions which can approximate a continuous complex valued function for CVNN node processing. The choice of an activation function determines the convergence of the complex back propagation algorithm and its generalization characteristics. In this paper we have compared the performance of various activation functions on the complex XOR problem for the complex multiplicative neural network. © 2011 IEEE.

Nowadays, reduction of energy-consumption in Mobile Ad-Hoc Networks (MANETs) has been a herculean task. Appropriate location-based routing protocols like Location-Aided Routing-1 (LAR-1) can be incorporated for reducing the energy consumption as it extends the network lifetime in dynamic network. The research work proposed integrating energy-conservation along with LAR-1 route-discovery mechanism, named as New-Location-Aided Routing-1 (N-LAR-1). In this paper, developments of performance-metrics using this N-LAR-1 approach have been reported. Affirmative results have been achieved through N-LAR-1 by utilizing the sleep or inactive mode condition of mobile nodes in Ad-Hoc Networks. It has been observed that performance of N-LAR-1 is better than N-DSR approach. © 2006-2014 by CCC Publications.

Phase Transitions | Year: 2011

The structural phase transition and electronic properties at ambient (B1-phase) and high pressure (B2-phase) of heavy rare earth monoantimonides (RESb; RE = Ho, Er, and Tm) have been studied theoretically using the self-consistent tight binding linear muffin tin orbital method. These compounds show metallic behavior under ambient condition and undergo a structural phase transition to the B2 phase at high pressure. We predict a structural phase transition from the B1 to B2 phase in the pressure range 30.0-35.0 GPa. Apart from this, the ground state properties, such as lattice parameter and bulk modulus are calculated and compared with the available theoretical and experimental results. © 2011 Taylor & Francis.

The effect of curing on activation energy and dielectric properties of carbon black-epoxy (CB-EP) composites has been reported at different temperatures and frequencies. The activation energy was found to be higher for the room temperature cured CB-EP samples as compared with the thermally cured CB-EP samples. Curing behavior of epoxy nanocomposites prove that epoxide molecules contribute to the curing reaction and reacted with them to form a cross-linked network. Dielectric constants of thermally cured CB-EP samples were higher than the room temperature cured samples. The results showed that activation energy, decreased with an increase in the concentration of carbon black in the composite, which may be due to an increase of polarization energy and/or charge carrier density leading to a decrease of the domain boundary potential of carbon black aggregates into the epoxy matrix. At room temperature, the electrical conductivity is due to electron tunneling and hopping. Dielectric constant of the CB-EP composite increase with increase in temperature and decreases with an increase in frequency from 0.5 kHz to 10 kHz for both room temperature cured and thermally cured specimens. The peak height of the dielectric constant curve of both cured samples decreases with increasing frequency. ©2015 Elsevier B.V. All rights reserved.

The foundation of a tall building frame resting on settable soil mass undergoes differential settlements which alter the forces in the structural members significantly. For tall buildings it is essential to consider seismic forces in analysis. The building frame, foundation and soil mass are considered to act as single integral compatible structural unit. The stress-strain characteristics of the supporting soil play a vital role in the interaction analysis. The resulting differential settlements of the soil mass are responsible for the redistribution of forces in the superstructure. In the present work, the nonlinear interaction analysis of a two-bay ten-storey plane building frame- layered soil system under seismic loading has been carried out using the coupled finite-infinite elements. The frame has been considered to act in linear elastic manner while the soil mass to act as nonlinear elastic manner. The subsoil in reality exists in layered formation and consists of various soil layers having different properties. Each individual soil layer in reality can be considered to behave in nonlinear manner. The nonlinear layered system as a whole will undergo differential settlements. Thus, it becomes essential to study the structural behaviour of a structure resting on such nonlinear composite layered soil system. The nonlinear constitutive hyperbolic soil model available in the literature is adopted to model the nonlinear behaviour of the soil mass. The structural behaviour of the interaction system is investigated as the shear forces and bending moments in superstructure get significantly altered due to differential settlements of the soil mass.

The building frame and its foundation along with the soil on which it rests, together constitute a complete structural system. In the conventional analysis, a structure is analysed as an independent frame assuming unyielding supports and the interactive response of soil-foundation is disregarded. This kind of analysis does not provide realistic behaviour and sometimes may cause failure of the structure. Also, the conventional analysis considers infill wall as non-structural elements and ignores its interaction with the bounding frame. In fact, the infill wall provides lateral stiffness and thus plays vital role in resisting the seismic forces. Thus, it is essential to consider its effect especially in case of high rise buildings. In the present research work the building frame, infill wall, isolated column footings (open foundation) and soil mass are considered to act as a single integral compatible structural unit to predict the nonlinear interaction behaviour of the composite system under seismic forces. The coupled isoparametric finite-infinite elements have been used for modelling of the interaction system. The material of the frame, infill and column footings has been assumed to follow perfectly linear elastic relationship whereas the well known hyperbolic soil model is used to account for the nonlinearity of the soil mass.

The back propagation algorithm calculates the weight changes of artificial neural networks, and a common approach is to use a training algorithm consisting of a learning rate and a momentum factor. The major drawbacks of above learning algorithm are the problems of local minima and slow convergence speeds. The addition of an extra term, called a proportional factor reduces the convergence of the back propagation algorithm. We have applied the three term back propagation to multiplicative neural network learning. The algorithm is tested on XOR and parity problem and compared with the standard back propagation training algorithm.

Pressure induced structural phase transition at high pressure, elastic constants and variation of elastic constants with pressure for LuX (X = S, Se, Te) compounds have been studied theoretically by using an interionic potential theory with modified ionic charge introduced to include the Coulamb screening effect due to localized f-electrons.
