This article is mainly focusing on the procedure adopted to develop and validate a tool to study higher secondary students' perceived peer pressure. Based on the review of related literature and group discussion, initially the researcher generated 50 items on perceived peer pressure and subsequently modified in to 35 items on the basis of experts' opinion. The first try-out on 100 higher secondary students resulted in selection of 30 items and Cronbach’s Alpha value was found to be 0.942. Again the tool was administered to 300 higher secondary students and based on the factor analysis the 30 items were categorized under three dimensions. The dimensions are: Yielding to Peer Pressure, Resistance to Peer Pressure and Peers Encouragement. The reliability and validity value of the final tool was found to be 0.942 and 0.971 respectively. Hence, the perceived peer pressure scale is found to be valid for application.
A Learning Content Management System (LCMS) is an integrated multi-user administrative, authoring, and delivery platform. It allows administrators to host, schedule, manage registrations, assess, test, and track online training activities. These systems also allow Instructional Designers to create and house course materials, and learners to access course schedules, register for training, take assessments, and manage transcripts. The tools may base on content management or learning content management. Presently a composition of Learning Management System (LMS) and Content Management System (CMS) is used in eLearning. This paper helps you to understand the basic functionality of LMS, CMS and LCMS and how these are helpful in eLearning.
This paper provides an in-depth review on the technologies being considered for recent and future wireless cellular networks based on cooperative communication with reduction in energy. Initially, the evolution from fourth generation (4G) to fifth generation (5G) is described in terms of performance characteristics and major requirements. The technology developed by the 3GPP community, which supports the integration of current and future services. The fifth generation (5G) cellular networks will require a major paradigm shift to satisfy the increasing demand for higher data rates, reduced latencies, better energy efficiency, and reliable connectivity through femto-cell based relays. These relay nodes are equipped with energy harvesting technique in cooperative networks for the improvement in energy efficiency. Unlike conventional energy source, the fluctuation in energy flow causes performance degradation. To overcome the above drawbacks, energy harvesting technique and other methodologies are explained together with possible improvements, challenges and few approaches that have been considered in this paper.
In any real time control application, the controller is expected to give optimal results irrespective of plant non-linearity, operating point change, component non-linearity and saturation. Fuzzy Logic Control (FLC) meets the control objective as it crafts the human experience in the form of If-Then rules. As the gain factors or scaling factors are constant in conventional FLC, Autotuning FLC with tuned scaling factors take over the charge. Further, in real time controllers, the memory constraint is dominant. As a solution, reduction of existing fuzzy rule base by subtractive clustering and optimization of the reduced rule set via neural network is proposed. Autotuning of input scale factors clubbed with reduction and optimization of a controller rule set is proposed to meet out the dynamic control of real time spherical tank process. The efficacy of the proposed approach is compared with real time servo and regulatory results of conventional FLC and AFLC of the spherical tank process
The mining of health care data is important aspect for the forecast of critical disease like cancer. In health care data mining various tools and techniques are available and applicable from machine learning. Machine Learning offers popular effective technique of classification for the purpose of mining voluminous dataset of health care. This paper implements the different traditional classifiers decision tree, k-nearest neighbor, support vector machine and modified ensemble classifier random forest for classification of health/diseased entities from the UCI data set for Cancer. The paper proposes the feature matrix extracted from majority voting ensemble classifier random forest mapped to SVM. Then it is implemented on three variations of cancer data set. Random forest shows the great results in terms of reduction in features, overfitting by averaging several tree, and also algorithm show less variance by using multiple tree, reduce the chance of stumbling across a classifier that doesn’t perform well because of the relationship between train and test data. In Random Forest, randomness is introduced by identifying the best split feature from a random subset of available features. These available important features further classified by powerful supervised machine learning algorithm named support vector machine. The main purpose of feature selection approach is to select a minimal and relevant feature subset for the given dataset and maintaining its original representation. This approach enhances the performance of SVM classifier and give rise to modified the majority vote ensemble classifier. The proposed hybrid mechanism of random forest feature matrix and SVM classification has shown 1.3% increment in accuracy for reduced cancer data set and this is verified from three reduced cancer data sets. This paper also demonstrates better accuracy of proposed ensemble classifier by comparative analysis with existing classifiers mechanism.
Information Science as a subject is an important interdisciplinary knowledge cluster and is very much close to Information Technology and Computer Science. But Information Science also deals with some other knowledge gradients such as Information Studies, Knowledge Management and hence Management Science. Still, MTech or BTech programme is mainly popular in India, it’s neighbouring countries and some UK Asian countries. As far as Information Science with MTech is concerned, not a single programme available on this nomenclature; but huge possibilities are there to introduce such programme with mixing up Engineering faculties with existing Information Science schools. Thus, this paper discusses about Information Science, it’s changing nature, and also about need and potentiality of five years integrated MTech- Information Science programme
Information is one of the valuable assets these days for several reasons. Information is needed in almost all the organizations and institutions regardless of type. Initially Information Service was mainly provided by the information foundation such as information centre, documentation centre, data centre, libraries, information kiosk with short range services and long range services. Though, later on the need of information create a separate information zone in other organization and hence, in general information foundation and organizational information unit computing is a major tool and thus the question of eco-friendly computing services are evolved ; and later on and most recently Green Information Services. This paper talks about Green and Eco-friendly Information Services and need of such services including strategy and policy to offer such services.
In this work I present a systematic way by which we can monitor, quantify and also improve the reliability of outgoing emerging Internet services. In this paper our focus is on the Internet services allows us to access huge amount of Information such as text, graphics, Sound, software and so on, over the Internet by the Internet Services Providers. There are different types of Internet services such as- Communication Services – This service divided into Electronic mail, Telnet, News group, Internet relay chat, Mailing lists, Internet telephony, Instant messaging, Information Retrieval Services – This service divided into Archie, Gopher, File transfer protocol, Very easy rodent oriented net wide index computer achieved, Web Services, World Wide Web.
Blockchain is a decentralized transaction and data management technology developed first for Bitcoin cryptocurrency. The interest in Blockchain technology has been increasing since the idea was coined in 2008. The reason for the interest in Blockchain is its central attributes that provide security, anonymity and data integrity without any third party organization in control of the transactions, and therefore it creates interesting research areas, especially from the perspective of technical challenges and limitations. This paper highlights the architecture, benefits and applications of Blockchain Technology.
