Monte Carlo simulation has been performed to study the rupturing process of thin polymer film under strong confinement. The change in mean square displacement; pair correlation function; density distribution; average bond length and microscopic viscosity are sampled by varying the molecular interaction parameters such as the strength and the equilibrium positions of the bonding, non-bonding potentials and the sizes of the beads. The variation in mean square angular displacement χθ=[<Δθ2>−<Δθ>2] fits very well to a function of type y(t)=A+B⁎e−tτ. This may help to study the viscous properties of the films and its dependence on different parameters. The ultra thin film annealed at high temperature gets ruptured and holes are created in the film mimicking spinodal dewetting. The pair correlation function and density profile reveal rich information about the equilibrium structure of the film. The strength and equilibrium bond length of finite extensible non-linear elastic potential (FENE) and non-bonding Morse potential have clear impact on microscopic rupturing of the film. The beads show Rouse or repetition motion forming rim like structures near the holes created inside the film. The higher order interaction as dipole–quadrupole may get prominence under strong confinement. The enhanced excluded volume interaction under strong confinement may overlap with the molecular dispersion forces. It can work to reorganize the molecules at the bottom of the scale and can imprint its signature in complex patterns evolved. © 2017 Elsevier B.V.

This paper deals with the springback problems of elliptical section bars of non-linear work-hardening materials under the torsional loading. Using the deformation theory of plasticity, a numerical scheme based on the finite difference approximation has been proposed. The growth of the elastic-plastic boundary and the resulting stresses while loading, and the springback and the residual stresses after unloading are calculated. © 2017 Elsevier Ltd.

In this paper a concept of modified source has been introduced in the design of fully-depleted silicon-oninsulator (SOI) n- and p-MOSFET structures to improve its electrical performance. The aim of the work is to propose a device which is suitable for low power digital applications. Another structure proposed in this paper is a tunnel diode body contact fully-depleted SOI n- and p-MOSFET. Both of these structures were compared and contrasted with available tunnel diode body contact partially-depleted SOI MOSFETs and other similar structures. The proposed MOS structures of n- and p-type shows reduced Ioff current and improved Ion to Ioff current ratio. These structures exhibit lower sub-threshold slope and area consumed by the device is also less. The devices were then used to form CMOS inverter circuits so as to evaluate its digital performance. The proposed structures and circuits were designed and simulated using Sentaurus device simulator and Cogenda device simulator. © 2017 by American Scientific Publishers. All rights reserved.

Reconfigurable manufacturing system is a new type of manufacturing system which can change its capacity and functionality very easily and quickly whenever required. RMS (reconfigurable manufacturing system) has capacity and functionality exactly what is required. RMS is adjustable to the fluctuating demands and it can be easily upgraded with new process technology. Reconfigurability of a manufacturing system is measured in terms of cost, effort and time. It is the ability of a manufacturing system to be reconfigured quickly with low reconfiguration effort at low cost. In the present work, reconfigurability has been considered in Continental Automotive Components Pvt. Ltd. on the basis of RMS principles. A modified reconfigurable layout has been proposed for an assembly line and scheduling of the products has been done for the criteria reconfiguration effort, profit over cost and due date. Scheduling of the products has been done using the integrated approach of Shannon entropy and RIM (Reference Ideal Method). R program has been written for scheduling. Sensitivity analysis has been conducted for the problem. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Present paper deals with the thermodynamic investigation of influence of different parameters in steam injected cooled gas turbine based combined cycle power plant employing vapor absorption cooling of inlet air and two pressure heat recovery steam generator. Vapor absorption cooling scheme is run by utilizing the heat energy of the exhaust gas at the exit of HRSG. Gas turbine blades are cooled using film cooling technique. A study of the influence of ambient conditions, cycle pressure ratio, and turbine entry temperature on plant performance has been carried out. It has been noted that the efficiency of gas turbine improves by up to 6.91% and specific work output enhances by 16.42% with the integration of vapor absorption inlet air cooling to the simple cycle. The CCPP specific work output advances 17.34% at given turbine entry temperature as the steam to air ratio increases from 3% to 7% at the cycle pressure ratio of 24. Similarly thermal efficiency of CCPP increases by 6.78% for same cycle pressure ratio of 24 and the constant increment in steam to air ratio from 3 to 7%. © 2017 Elsevier Ltd

Ammonium formate in presence of palladium-carbon is an efficient system for catalytic transfer hydrogenation of several functional groups under mild conditions. However, this system was not found effective for reduction of quinones to hydroquinones, although reduction could be effected with phosphinic acid, phosphinates or cyclohexene as donors. A reexamination of this reaction suggested that formates were good hydrogen donors in this reduction but the reaction was inhibited due to quinhydrone formation. A simple expedient of maintaining low concentration of quinone during catalytic transfer hydrogenation reduction gave excellent yields of the hydroquinone. Compared to formates, formic acid was found to be a poor hydrogen donor.

An ac-to-ac converter has been developed to convert the variable input frequency in wind energy conversion system (WECS) to a constant output frequency of 50 Hz for a distributed generation unit. The switching strategy and control mechanism for the converter is presented using time domain simulations in MATLAB environment. A specific triggering pattern has been generated for the switching devices in the converter to achieve desired polarity of the output voltage across the distributed load. The harmonics in the input supply side of the converter are mitigated by using delta modulation technique, whereas in the output of the converter, passive filtering has been used along with delta modulation technique. The design and implementation issues of the modulation technique and the switching scheme are discussed in detail with suitable simulation and experimental results. The analysis and properties of the proposed solution is compared with the known solutions. It has been concluded that an ac-ac converter is technically a viable option to interface a wind turbine to a utility grid. 1551-3203 © 2015 IEEE.

In restructured electricity markets, forecasting electricity parameters are most essential tasks & basis for any decision making. Forecasting price in competitive electricity markets is difficult for consumers and producers in order to plan their operations and to manage their price risk, and it also plays a key role in the economic optimization of the deregulated power industry. Accurate, short-term price forecasting is an essential instrument which provides crucial information for power producers and consumers to develop accurate bidding strategies in order to maximize their profit. In this paper artificial intelligence (AI) has been applied in short-term price forecasting that is, the one hour ahead price forecast of the electricity market. A new artificial neural network (ANN) has been used to compute the forecasted price in Ontario electricity market using MATLAB R13b. The data used in the forecasting are hourly historical data of the electricity load and price of Ontario electricity market. The simulation results have shown highly accurate one hour ahead forecasts with very small error in price forecasting. © 2015 IEEE.
