    This paper presents the experimental outcomes regard to the flashover performance of pin, shackle and disc insulators under contaminated conditions. For making contaminated surface various samples are made like salt, dust, industry pollution and miscellaneous foreign particles of wet and dry conditions as per IEC testing techniques. Moreover, each insulator has been tested under above mentioned conditions. For each insulator its breakdown voltages were measured. After doing performance analysis of different insulators under contaminated condition measurement of breakdown voltages are done with incorporation of real field application of insulators and making analogy with various regions of India

    Understanding of inclined-work-related risk of falls and developing novel practical engineering controls for reducing this risk of falls among hilly working population remains in high demand. Standing on sloped surfaces provides a unique environment for examining the biomechanics and neural control of standing. The present investigation examined the variability of postural signals when standing on inclined surfaces and with load carriages by linear and nonlinear analysis. The purpose of this study was to determine if the sloped surface deteriorated in postural stability among healthy individuals with two distinctive kinds of load carriage methods head versus posterior load carriage. We also examined the effects of distinct magnitudes of load on these conditions. Postural control was assessed objectively using forceplates and subjectively through perceived stability ratings. The results indicate significant differences in mediolateral COP ranges, COP velocities and COP area with interaction in surface inclinations and methods of load carriage. We found that head load carriage when standing on uphill afflicted and engendered increased balance deterioration in healthy young subjects. We also found the significantly lower complexity of postural signals for head load carriage as measured by entropy. Apropos to this mean subjective perceived rating was also least in this load-bearing condition. Understanding these underlying mechanisms of postural control with load carriage strategies in humans could productively help in developing efficacious preventive strategies to reduce the incidence of falls from inclined slopes

    Common path interference in Zener tunneling is a universal phenomenon

    We show that the probability of electric field induced interband tunneling in solid state systems is generically a non-monotonic (oscillatory) function of the applied field. This unexpected behavior can be understood as arising due to a common path interference between two distinct tunneling solutions. The phenomenon is insensitive to magnetic field, and arises whenever the low energy dispersion relation contains higher order terms in addition to the usual p2p^2 term. Such higher order terms are generically present, albeit with small co-efficient, so that the oscillatory Zener tunneling is a universal phenomenon. However, the first `Zener oscillation' occurs at a transmission probability which is exponentially small when the co-efficient of the higher order terms is small. This explains why this oscillatory aspect of Zener tunneling has been hitherto overlooked, despite its universality. The common path interference is also destroyed by the presence of odd powers of pp in the low energy dispersion relation. Since odd powers of pp are strictly absent only when the tunneling barrier lies along an axis of mirror symmetry, it follows that the robustness of the oscillatory behavior depends on the orientation of the tunneling barrier. Bilayer graphene is identified as a particularly good material for observation of common path interference, due to its unusual nearly isotropic dispersion relation, where the p4p^4 term makes the leading contribution

    Objective The knowledge and utilization of Iron and folic acid tablets supplementation of the adolescent girls in Ahmedabad district. Setting The study was conducted over a time span of 20 weeks period, from April 2011 till Aug 2011 in selected areas of Ahmedabad district, which has an approximate population of 15,94,010 as per census 2001. Study design Cross sectional observational study. Participants All the adolescent girls in the population surveyed by MICS 2011. Methodology 30 clusters sampling method based on PPS (Probability Proportional to Size) for cluster selection. Results 431 adolescent girls were included in the survey of total population of 6076. The result showed that 51.5% (222) girls went to school and only 36.2% (156) received IFA tablets. Out of them 66% (103) girls stopped taking these tablets due to one or other side effects of the tablets. Nearly 47.4% (74) girls were unaware of the positive effects of these tablets on their health

    Generative Boltzmann Adversarial Network in Manet Attack Detection and QOS Enhancement with Latency

    Mobile Ad-Hoc Network (MANET) are considered as self-configured network those does not have any centralized base station for the network monitoring and control. MANET environment does not control architecture for routing for the frequent maintenance of topology. The drastic development of Internet leads to adverse effect of development in MANET for different multimedia application those are sensitive to latency. Upon the effective maintenance of the QoS routing route discovery is performed to calculate queue and contention delay. However, the MANET requirement comprises of the complex procedure to withstand the Quality of Service (QoS) with Artificial Intelligence (AI). In MANET it is necessary to compute the MANET attacks with improved QoS with the reduced latency as existing model leads to higher routing and increased latency.  In this paper proposed a Generative Boltzmann Networking Weighted Graph (GBNWG) model for the QoS improvement in MANET to reduce latency. With GBNWG model the MANET model network performance are computed with the weighted graph model. The developed weighted graph computes the routes in the MANET network for the estimation of the available path in the routing metrices. The proposed GBNWG model is comparatively estimated with the conventional QOD technique. Simulation analysis stated that GBNWG scheme exhibits the improved performance in the QoS parameters. The GBNWG scheme improves the PDR value by 12%, 41% reduced control packets and 45% improved throughput value

    Due to the expansion of Internet of Things (IoT), the extensive wireless, and 4G networks, the rising demands for computing calls and data communication for the emergent EC (EC) model. By stirring the functions and services positioned in the cloud to the user proximity, EC could offer robust transmission, networking, storage, and transmission capability. The resource scheduling in EC, which is crucial to the accomplishment of EC system, has gained considerable attention. This manuscript introduces a new lighting attachment algorithm based resource scheduling scheme and data integrity (LAARSS-DI) for 4G IoT environment. In this work, we introduce the LAARSS-DI technique to proficiently handle and allot resources in the 4G IoT environment. In addition, the LAARSS-DI technique mainly relies on the standard LAA where the lightning can be caused using the overall amount of charges saved in the cloud that leads to a rise in electrical intensity. Followed by, the LAARSS-DI technique designs an objective function for the reduction of cost involved in the scheduling process, particularly for 4G IoT environment. A series of experimentation analyses is made and the outcomes are inspected under several aspects. The comparison study shown the improved performance of the LAARSS-DI technology to existing approaches
