Mathematical Analysis of Queue with Phase Service: An Overview
Richa Sharma
Advances in Operations Research , 2014, DOI: 10.1155/2014/240926
Abstract: We discuss various aspects of phase service queueing models. A large number of models have been developed in the area of queueing theory incorporating the concept of phase service. These phase service queueing models have been investigated for resolving the congestion problems of many day-to-day as well as industrial scenarios. In this survey paper, an attempt has been made to review the work done by the prominent researchers on the phase service queues and their applications in several realistic queueing situations. The methodology used by several researchers for solving various phase service queueing models has also been described. We have classified the related literature based on modeling and methodological concepts. The main objective of present paper is to provide relevant information to the system analysts, managers, and industry people who are interested in using queueing theory to model congestion problems wherein the phase type services are prevalent. 1. Introduction In congestion situations of day-to-day as well as industrial problems, it has been realized that queueing models with phase service play vital role in depicting and analyzing queueing situations. Our aim in this paper is to provide an overview on the conceptual aspects for the phase service queueing models in different frameworks. In traditional queueing models, all arriving customers/jobs require main service which is to be completed in single phase. In many real time systems the service may be completed in many phases. The concept of optional phase services has been studied by many researchers for improving the grade of service. Sometimes only a few arriving customers require the optional services along with essential service for their satisfaction. Queueing models with phase service accommodate the real-world situations more closely. The purpose of present paper is to provide overview of queueing models with phase service and its applications in real life queueing problems. The motivation for studying the queueing systems with phase service comes from numerous versatile applications in the performance evaluation and dimensioning of production and manufacturing systems, computer and communication networks, inventory and distribution systems, and so forth. During the last few decades, attention has been paid increasingly by many researchers in studying the phase service queueing models. Many developments have taken place from time to time in this field and need further research in this regard. Various studies on phase service queueing models have appeared during literature 80’s
An Approach to Human Adaptability towards its Built Environment: A Review  [PDF]
Richa Tiwari, Mukesh Pandey, Anupama Sharma
Energy and Power Engineering (EPE) , 2010, DOI: 10.4236/epe.2010.22013
Abstract: This paper deals with the human adaptability to its built environment. The built environment as we know it rarely finds itself adapting to its surrounding context, whether it be on the level of interaction with humans or the climate. Humans and nature both are in a constant state of flux; moving, changing, sensing, and reacting to their context and information they gather and perceive. A barrier is formed between the built environment and humans and nature due to the fact that their inherent characteristics are utterly contrasting. It is commonly estimated that persons in urban areas spend at least 80% of their time indoors. This suggests that the quality of the indoor environment can have a significant impact on comfort, health, and overall sense of well being. The indoor environment of buildings should thus be designed and controlled, as to provide a comfortable and healthy space for occupants. In order to maintain the quality of the indoor environment, we mechanically condition our buildings to achieve constant, uniform and comfortable environments. The maintenance of thermal equilibrium between the human body and its environment is one of the primary requirements. History of thermal comfort and climate design shows a definite relation between them and research is needed to know “What are comfort conditions?” and “How buildings could adapt themselves to these conditions”.
Does the Availability of Community Health Worker/Mobile-Health Van Unit within the Community Impacts Neonatal Survival?  [PDF]
Ajay Pandey, Dilip C. Nath, Richa Sharma
Open Journal of Statistics (OJS) , 2017, DOI: 10.4236/ojs.2017.75057
Abstract: This study uses the data from the National Family Health Survey round-2. Using hierarchical linear models the role of community level variables in predicting neonatal deaths at individual level is analyzed. SAS sub-routine PROC GLIMMIX is used for hierarchical linear modeling. Findings re-enforce the importance of mother’s literacy and tetanus toxid vaccination during pregnancy in predicting neonatal deaths at individual level. At community level, though the magnitude of the presence of either a private doctor, or a visiting doctor, or a village guide, or a traditional health attendant, or the presence of mobile health van unit within community is in an expected direction, the effect is statistically not significant. In order to capture true impact of community level intervention of program success it is imperative that the large demographic surveys should incorporate more and more community level indicators while designing these surveys.

Arvind Mohan, Ajay Pandey, Richa Sharma
Open Journal of Statistics (OJS) , 2019, DOI: 10.4236/ojs.2019.91003
Abstract: Female age at marriage in Uttar Pradesh is amongst the lowest in India. Previous studies on female age at marriage in an Indian context primarily focused on the individual level factors impacting female age at marriage. Community level factors that influence the female age at marriage in Uttar Pradesh were non-existent. In this study, the impact of community presence of mass media is studied using Hierarchical Linear Models. Thus using the data from NFHS-2, the study explores the within community presence of any forms of print, electronic or local mass media and its impact on female age at marriage in Uttar Pradesh. Total of 7175 currently married individual women were nested in 317 rural communities across Uttar Pradesh. Hierarchal linear modeling using SAS PROC MIXED was used in the study. The intra-class correlation of 0.13 indicates fair bit of clustering of female age at marriage within communities. Thirteen percent of the differences in female age at marriage are due to between community differences in Uttar Pradesh. Communities’ exposure to any forms of mass media has a positive impact on female age at marriage in Uttar Pradesh.

Role of Adjacency Matrix & Adjacency List in Graph Theory
Harmanjit Singh,Richa Sharma
International Journal of Computers & Technology , 2012,
Abstract: Today, graph theory has become major instrument that is used in an array of fields. Some of these include electrical engineering, mathematical research, sociology, economics, computer programming/networking, business administration and marketing. Indeed, many problems can be modeled with paths formed by traveling along the edges of a certain graph. Frequently referenced problems are efficiently planning routes for mail delivery, garbage pickup and snow removal, which can be solved using models that involve paths in graphs. Given these kinds of problems, graphs can become extremely complex, and a more efficient way of representing them is needed in practice. This is where the concept of the adjacency matrix & adjacency list comes into play.

Abstract: Color Transformation of image is modify the color of image in the another one. Till yet many researchers did work in this field to enhance images for the people suffering from color blindness and to enhance image contrast. Many methods are used to transfer the color of image and color blind viewers are enhancing the image contrast and differentiate those colors. These methods Linear Color Transformation PSO, daltonization are used and make a optimize color table that are taking more time .Here we are going to propose the BFO technique and optimize color table with BFO for the given number of generations. Using BFO makes color transform table more accurately rather than the normal morphological and mathematical based approaches and reduce the processing time.
Phenolic Acids from Parthenium hysterophorus: Evaluation of Bioconversion Potential as Free Radical Scavengers and Anticancer Agents  [PDF]
Richa Panwar, Asvene Kumar Sharma, Dharm Dutt, Vikas Pruthi
Advances in Bioscience and Biotechnology (ABB) , 2015, DOI: 10.4236/abb.2015.61002
Abstract: Parthenium hysterophorus is a globally recognized invasive alien weed that prominently colonizes grazing areas and cultivated lands causing adverse effect on crop production. Major allelochemicals released from parthenium include sesqueterpene lactones and phenolic acids. Among these the presence of caffeic, vanillic and ferulic acids is of industrial significance as they possess potent free radical scavenging and anticancer activities. This study reports for the first time, high total phenolic acid content (20.82 ± 0.82 mg GAE/g dry sample) in parthenium. The GC-MS analysis indicated the presence of ferulic, p-coumaric, vanillic and gallic acid as major phenolic components. Free radical scavenging activity of the phenolic acids extract gave an EC50 value 130.4 μg/ml when measured using DPPH assay. Anticancer activity of parthenium phenolic extract against A-498 (IC50 0.5237 μg/ml) and MDA-MB231 (IC50 and 0.2685 μg/ml) cancerous cell lines indicated its potential to be used as anticancer agent.
Reduce Scanning Process for Efficient Mining Tree in Association Rule Mining
Richa Sharma,Mr. Premnarayan Arya
International Journal of Technological Exploration and Learning , 2012,
Abstract: The essential aspect of mining association rules is to mine the frequent patterns. Due to native difficulty it is impossible to mine complete frequent patterns from a dense database. FP-growth algorithm has been implemented using a Array-based structure, known as a FP-tree, for storing compressed frequency information. Numerous experimental results have demonstrated that the algorithm performs extremely well. But In FP-growth algorithm, two traversals of FP-tree are needed for constructing the new conditional FP-tree. In this paper we present a novel ABFP tree technique that greatly reduces the need to traverse FP-trees and array based FP tree, thus obtaining significantly improved performance for FP-tree based algorithms. The technique works especially well for sparse datasets. We then present a new algorithm which use the FP-tree data structure in combination with the FP- Experimental results show that the new algorithm outperform other algorithm in not only the speed of algorithms, but also their CPU consumption and their scalability.
