Designs of wideband recursive digital integrators and differentiators are presented. The integrators are obtained by interpolating some of the popular digital integration techniques. The procedure consists of obtaining an integrator and then modifying its transfer function appropriately to get a stable differentiator. The proposed integrators and differentiators accurately approximate the ideal integrator and ideal differentiator over the whole Nyquist frequency range and compare favourably with the existing integrators and differentiators. The suggested integrators and differentiators are of third-order and highly suitable for real-time applications, where linear phase property is not necessary. © 2010 The Institution of Engineering and Technology.

Sequential pattern mining is a vital problem with broad applications. However, it is also challenging, as combinatorial high number of intermediate subsequences are generated that have to be critically examined. Most of the basic solutions are based on the assumption that the mining is performed on static database. But modern day databases are being continuously updated and are dynamic in nature. So, incremental mining of sequential patterns has become the norm. This article investigates the need for incremental mining of sequential patterns. An analytical study, focusing on the characteristics, has been made for more than twenty incremental mining algorithms. Further, we have discussed the issues associated with each of them. We infer that the better approach is incremental mining on the progressive database. The three more relevant algorithms, based on this approach, are also studied in depth along with the other work done in this area. This would give scope for future research direction. © 2013-IOS Press and the authors. All rights reserved. Source

Indian grid now totally synchronized and working as National Grid is poised for multi-prong development. It has already implemented and has ambitious plans for Smart Grid applications in both transmission and distribution segments. With the progress in Information and Communication Technology, full advantage of it is being taken for evolving the Smart Grid. A number of measures like implementation of wide area monitoring system using phasor measurement technology, continuance of network embedding with HVDC system, etc. are the means at transmission level to achieve the goal in this respect. While integration of renewable energy sources to grid with energy storage and transmitting surplus to far-flung areas of the country through interconnection is being made possible, on distribution front due to deployment of advanced metering infrastructure, demand response enabled peak load management is being attempted. With the proliferation of electric vehicle and other modes of transportation based on electricity, further step is contemplated to take care of the same, both as load and storage with increase in number. © 2014 IEEE.

In component-based development, software systems are built by assembling components already developed and prepared for integration. To estimate the quality of components, complexity, reusability, dependability, and maintainability are the key aspects. The quality of an individual component influences the quality of the overall system. Therefore, there is a strong need to select the best quality component, both from functional and nonfunctional aspects. The present paper produces a critical analysis of metrics for various quality aspects for components and component-based systems. These aspects include four main quality factors: complexity, dependency, reusability, and maintainability. A systematic study is applied to find as much literature as possible. A total of 49 papers were found suitable after a defined search criteria. The analysis provided in this paper has a different objective as we focused on efficiency and practical ability of the proposed approach in the selected papers. The various key attributes from these two are defined. Each paper is evaluated based on the various key parameters viz. metrics definition, implementation technique, validation, usability, data source, comparative analysis, practicability, and extendibility. The paper critically examines various quality aspects and their metrics for component-based systems. In some papers, authors have also compared the results with other techniques. For characteristics like complexity and dependency, most of the proposed metrics are analytical. Soft computing and evolutionary approaches are either not being used or much less explored so far for these aspects, which may be the future concern for the researchers. In addition, hybrid approaches like neuro-fuzzy, neuro-genetic, etc., may also be examined for evaluation of these aspects. However, to conclude that one particular technique is better than others may not be appropriate. It may be true for one characteristic by considering different set of inputs and dataset but may not be true for the same with different inputs. The intension in the proposed work is to give a score for each metric proposed by the researchers based on the selected parameters, but certainly not to criticize any research contribution by authors.

Conformational studies of ε-CBz-L-lysine and L-valine block copoylpeptides using x- ray diffraction and CD spectra are described. The block copolypeptides contain valine block in the center and on both side of the valine are ε-CBz-L-lysine blocks. The conformation of the copolypeptides changes with increases in the chain length of ε- CBz-L- lysine blocks. When length of ε- CBZ- Llysine blocks is 9, the block copolypeptide has exclusive beta sheet structure. With the increase in chain length of ε-CBz-L-lysine blocks from 9 to 14, the block copolypeptide shows presence of both alpha helix and beta sheet components. With further increase in chain length of ε- CBz- L- lysine blocks, the beta sheet component disappears and block copolypeptides exhibits exclusive α -helix conformation. Source
