The nonlinear transient behavior of the delaminated composite curved shell panel under different kinds of mechanical loading is investigated in this analysis. The delaminated shell panel model is developed mathematically using two higher-order midplane theories in conjunction with the Green-Langrage type of geometrical nonlinear strains including all the nonlinear higher-order terms. Further, the desired nonlinear responses are computed numerically with the help of a unique computer code developed in the MATLAB® environment. The nonlinear numerical responses are computed using Newmark's time integration scheme together with the direct iterative method in conjunction with finite-element steps. Further, the convergence behavior of the present numerical results is checked. In addition, the validity of the present numerical responses is shown by comparing the results with those of the available published literature. Finally, the role of the size, location, and position of delamination as well as the effects of different design parameters (curvature ratio, aspect ratio, modular ratio, shell configuration, and constraint condition) on the nonlinear transient responses are computed through a wide variety of numerical examples and discussed in detail.

Plants with C4 photosynthesis are efficient in carbon assimilation and have an advantage over C3 photosynthesis. In C4 photosynthesis, the primary CO2 fixation is catalyzed by phosphoenolpyruvate carboxylase (PEPC). Here, we show that overexpression of Zea mays PEPC cDNA, under the control of 35S promoter, in Arabidopsis thaliana resulted in ~7–10 fold higher protein abundance and ~7–10 fold increase in PEPC activity in the transgenic lines than that in the vector control. We suggest that overexpression of PEPC played an anaplerotic role to increase the supply of 4-carbon carboxylic acids, which provided carbon skeletons for increased amino acid and protein synthesis. Higher protein content must have been responsible for increased metabolic processes including chlorophyll biosynthesis, photosynthesis, and respiration. Consequently, the PEPC-overexpressed transgenic plants had higher chlorophyll content, enhanced electron transport rate (ETR), lower non-photochemical quenching (NPQ) of chlorophyll a fluorescence, and a higher performance index (PI) than the vector control. Consistent with these observations, the rate of CO2 assimilation, the starch content, and the dry weight of PEPC-overexpressed plants increased by 14–18 %, 10–18 %, and 6.5–16 %, respectively. Significantly, transgenics were tolerant to salt stress as they had increased ability to synthesize amino acids, including the osmolyte proline. NaCl (150 mM)-treated transgenic plants had higher variable to maximum Chl a fluorescence (Fv/Fm) ratio, higher PI, higher ETR, and lower NPQ than the salt-treated vector controls. These results suggest that expression of C4 photosynthesis enzyme(s) in a C3 plant can improve its photosynthetic capacity with enhanced tolerance to salinity stress. © 2016 Springer Science+Business Media Dordrecht

Composites based on ethylene acrylic elastomer (AEM) filled with a special type of conductive carbon black (CCB) have been prepared by two-roll mixing mill. The compression-molded sheet of the prepared composites have been subjected to electron beam (EB) radiation dose up to 400 kGy to induce radiation crosslinked composites. The crosslinked density has been calculated according to Flory-Rehner equation and is found to increase with increasing EB dose and CCB loading. Chain scission-to-crosslink density has been calculated by Charlesby-Pinner equation, which shows decreasing trend with increasing radiation dose. The dielectric relaxation behaviors of different doses of EB-treated AEM/CCB composites have been extensively studied as a function of frequency of applied electric field (101-106 Hz), CCB loading [0-30 phr (parts per hundred)], temperature (25-120 C), and EB dose (50-400 kGy). It is observed that the dielectric permittivity (ε′) increases with CCB loading and temperature, but decreases with increasing EB dose. This can be explained on the basis of interfacial polarization. Based on dielectric loss tangent (tan δ) values, it is observed that the dielectric relaxation time decreases with increases in the filler loading and temperature. However, it increases with increase in the radiation doses. Both the real and imaginary parts of the impedance (Z′ and Z″) have been found to decrease with increase in conductive filler loading. The AC conductivity (σac) increases with increase in the CCB concentration, test temperature, and radiation doses, which is attributed to the more pronounced hopping and tunneling mechanism. The percolation threshold (φ crit) occurred in the range of 16 phr CCB loading. The dispersions of CCB phase in AEM matrix below and above percolation have been captured by the transmission electron microscope photomicrographs. © 2012 Springer Science+Business Media, LLC.

In last few decades, Evolutionary computation and Swarm intelligence are two hot favorites for almost all types of researchers. Moreover, many contributions have been made in two directions: Genetic Algorithm (GA) and Particle Swarm optimization (PSO). But, some limitations in both the algorithms (complicated operator like crossover and mutation in GA and early convergence in PSO), are the major restricted boundaries for solving complex problems. In this paper, a hybridization of Particle swarm optimization and Genetic algorithm has been proposed with the back propagation learning based Multilayer perceptron neural network. The effectiveness of the proposed algorithm is shown through a no. of simulation steps with the help of the benchmark datasets considered from UCI machine learning repository. The performance of the algorithm is compared with other standard algorithms to show the steadiness and efficiency as well as statically significant. © Springer India 2015.

Conductive rubber composites based on ethylene acrylic elastomer (AEM) and conductive carbon black (CCB) were prepared by a two-roll mixing mill. From the transmission electron microscope photomicrographs, the uniform distribution of CCB aggregates and the interconnected CCB aggregates in the AEM matrix were observed. The bound rubber content of unvulcanized rubber was found to increase significantly with increasing CCB content. The effect of CCB concentration on the dynamic viscoelastic properties of AEM matrix was determined using a Rubber Process Analyzer (RPA 2000) in terms of strain sweep and frequency sweep of both uncured and cured AEM/CCB systems. The storage modulus (G) increased with an increase in CCB loading. In the case of strain sweep, the G values decreased with strain amplitude for both the systems, but the G was more for cross-linked AEM/CCB systems. The strain dependency of G for CCB-filled AEM systems can be explained on the basis of the Payne effect. The complex viscosity (η∗) of these systems increased with CCB loading, and it decreased with strain amplitude, which is due to the shear thinning effect. The tan δ for unvulcanized and vulcanized systems increased with the strain; however, the value of tan δ was <1 throughout the experimental strain range, which explains the elastic nature of the cured systems. The G increased with angular frequency for both the systems and the tan δ became independent upon the angular frequency after 10 Hz. The alternating current conductivity (σAC) increased with an increase in CCB loading at all frequencies and the system achieves the percolation at 20 phr CCB loading, which is in accordance with the rheological percolation. The direct current conductivity (σDC) also increased with an increase in CCB concentration. © The Author(s) 2013.

In present study aqueous Neem (Azadirachta indica A. Juss) extract was tested for the growth, yield and disease control of a common vegetable plant Brinjal (Solanum melongena L.). The neem extract increased shoot height, number of leaves, number of buds, number of flowers and number of fruits of Brinjal plant over control. Numbers of diseases were calculated as percentage and diseases per plant. The percentage of reduction of disease was calculated after the spray of neem extract. Neem extract was found as most effective agent in controlling leaf spot (82.33%) and wilt (41.34%) in comparison to control under field conditions. The result showed that neem leaf extract acts as potential source for the management of severe diseases in addition to its positive effect on growth parameters. © 2014 Academic Journals Inc.

Mobile ad hoc network is adaptive computing and self-configuring network that automatically form their own infrastructure without support of any base station. The IEEE standard 802.11 protocol is generally used for wireless LAN. This standard 802.11 specifies DCF mode of Mac protocol that does not support quality of service (QoS) as all stations have same priority. To develop the basic performance in real-time application such as video and audio, QOS is essential. So, the standard 802.11e specifies EDCF mode of Mac protocol that enhances the DCF to provide prioritized QOS. Most of the performance of this protocol have evaluated for ideal environment. In this paper, the performance of Mac protocol is evaluated through simulation by using QUALNET software without assigning any priority for non-ideal environment by using performance matrix such as throughput, delay, and jitter. © Springer India 2015.

Wireless communication systems, satellite communication and radar systems are generally used low pass microwave filter for frequency selection. The low pass microwave filters are essential for reject harmonic components which are above cut off frequency. High impedance and low impedance microstrip lines are used in stepped impedance microwave filter design. In this proposed filter describes the design of C-band microstrip line low pass filter. In this paper we have choose the bandwidth of 4GHz and implemented with FR4 substrate. Relative permittivity is 4.2 with a thickness of 62 mil for 6th order low pass filter. I have achieved the cut off frequency 4.010GHz for -3dB. The return loss is greater than -47 dB. The proposed low pass stepped impedance microwave filter describes the designing of Butterworth approximation and cut off frequency at 4GHz with an realization of microstrip line. This low pass filter design is simulated by Advanced Design System (ADS) software. © 2016 IEEE.
