    The development of plug-in hybrid electric vehicles will impact the operation of the power grid since the entrance of these vehicles in substantial numbers will sum to a sizable extra load. This thesis recommends an algorithm for an energy management system (EMS) to apportion constrained power accessible from the utility to a large number of PHEVs parked at a municipal parking deck whereas additionally taking the vehicle battery qualities and client inclination into thought. We start with an itemized portrayal of the framework operation and parts emulated by the proposal of a scientific skeleton for enhancement of power designation. We then recommend the formulation and solution for attaining the ideal assignment methodology taking state of charge augmentation at plug out time as the target. We accomplish by the performance of simulation results. In this thesis, an algorithm is recommended to optimally accomplish a huge number in plug-in hybrid electric vehicles (PHEV's) charging at a municipal parking deck. Differential Evolution optimization is utilized to dispense vitality effectively to the PHEV's. Requirements like vitality value, remaining battery capacity, and staying charging time are utilized. Recreation results are exhibited and talked about

    Exploitation of wild relatives of crop plants to a large extent depends on the efficient use of germplasm resources available in natural habitat and the centre of diversity. The mulberry, sole food for silkworm is cultivated for the production and development of silkworm industry. Four species of mulberry viz., M. indica L., M. alba L., M. laevigata Wall., and M. serrata Roxb., are reported in India. Among these species, M. serrata is endemic to North Western Himalayan belt and growing in the higher altitude ranging from 560 ? 2200m above mean sea level. As a part of survey and exploration, 54 samples of M. serrata were collected from three states i.e., Uttaranchal (45), Himachal Pradesh (07) and Jammu and Kashmir (02). During collection, morphological variability, details of habitat viz., natural abode of plant and other related data were recorded. The collected materials were established in the Ex-situ field gene bank of Central Sericultural Germplasm Resources Centre (CSGRC) for further study. The morphological, anatomical, reproductive and growth traits showed variation among the different collections of M. serrata. This paper deals with biodiversity, geographical distribution, utilization and conservation of M. serrata for posterity

    Relaxation behaviours in ferromagnetic monolayers

    In this article, we briefly review the studies on magnetic relaxation behaviours. The theoretical as well as experimental investigations are reported briefly. A major part of this article is devoted to the recent Monte Carlo investigations into the roles of boundary conditions, dynamics and the Geometrical structures on the relaxation of magnetic monolayers modelled by two-dimensional Ising ferromagnet. We have studied all these effects for a two dimensional Ising system with two types of deformations, namely preserving and area non-preserving.The Glauber protocol and Metropolis dynamical rules are employed in our simulations and we investigated the systems with both periodic and open boundary conditions. The major findings are the exponential relaxation and the dependence of relaxation time (τ\tau) on the aspect ratio RR (length over breadth). A power law dependence (τRs\tau \sim R^{-s}) has been observed for larger values of aspect ratio (RR). The linear thermal (TT) dependence of exponent (ss) has been noticed (s=aT+bs = aT + b). The transient behaviours of the spin-flip density have also been studied here for both surface and bulk/core. Both the saturated bulk/core and saturated surface spin-flip density are observed to follow the logarithmic dependence fd=a+b log(L)f_{d} = a + b~\log(L) with the system size (LL). For open boundary condition with any kind (Metropolis/Glauber) of dynamical rule, the faster relaxation has been observed. Similarly, Metropolis algorithm yields faster relaxation for any kind (open/periodic) of boundary condition. We appeal to the experimentalists for experimental support which may be applied in judicious {\it magnetic coating} of the credit cards for quicker response.Comment: This manuscript is withdrawn due to some technical reason
