Analysis of VANET geographic routing protocols on real city map
(Institute of Electrical and Electronics Engineers Inc., 2018) Kaur, H.; Meenakshi
Vehicular Ad hoc network (VANET) is an escalating field of research and laid basis for many newer technologies like Intelligent Transport Systems (ITS). Routing in VANETs plays crucial role in performance of networks. VANET protocols are classified as topology based and position based protocols. Research showed that position based protocols are more suited to VANETs as compared to topology based protocols because geographic routing does not involve an overhead and delay of maintaining routing tables instead geographic position of nodes is used for routing which can be obtained by Global Positioning System (GPS) device on vehicles. In this paper, two geographic routing protocols Anchor based Street and Traffic Aware Routing (A-STAR) and Greedy Perimeter Stateless Routing (GPSR) protocols are evaluated on real city map. Simulation of VANETs on real map scenarios provide accurate results and also useful to design and deploy VANETs in real world. Real world mobility model is important because it reflects real-world performance of protocols considered. Analysis of performance is carried in terms of throughput, packet delivery ratio, packet loss and average delay. Simulation of protocols is carried by varying density of nodes. A-STAR showed better performance on real city map over GPSR because A-STAR adopted Street awareness method of routing whereas GPSR works on Greedy forwarding and Routing around the perimeter methods. ? 2017 IEEE.
Bio-analytical applications of nicking endonucleases assisted signal-amplification strategies for detection of cancer biomarkers -DNA methyl transferase and microRNA.
(Elsevier, 2019) Mittal, S; Thakur, S; Mantha, A. K.; Kaur, H.
The low concentrations of cancer biomarkers in the blood have limited the utility of quantitative bioassays developed for the purpose. The advent of nicking endonucleases (NEases) as signal amplification tools have greatly enhanced the detection efficiency and provided a multi-optional platform to design target specific detection methods. The present review focuses on the prominent features of NEases, modified DNA probes (such as hairpin (HP) probes, molecular beacons, and G- quadruplex) that mediate cyclic cascade and role of helper enzymes. Application of NEase assisted signal amplification (NESA) has been discussed for diagnosis of two prominent cancer biomarkers viz. DNA methyl transferase (Dam MTase) and microRNA (miRNA). NESA mediated techniques such as rolling circle amplification (RCA), strand displacement amplification (SDA) and isothermal exponential amplification (EXPAR), have been compared in light of their future applications in clinical diagnosis. Significance of nanomaterials to achieve further amplification and NESA assays for simultaneous detection of miRNAs has also been conversed. It is anticipated that the information gained from the analyses of the prospects and limitations of NESA-based assays will be useful towards understanding the applications, and improvement of efficient isothermal exponential amplification strategies for highly sensitive and selective detection of cancer biomarkers.
An economic analysis of pesticide use in India: A case study of bathinda district
(CESER Publications, 2017) Kaur, H.; Kaur, S.
The excessive use of the pesticides in agriculture has not only increased production cost but also led to negative externalities. The present study is an attempt to analyse the socio-economic implications of pesticide use in Bathinda district known as the cotton belt due to its maximum area under cotton cultivation. An attempt has been made to find out the impact of pesticides on gross returns ofcotton and paddy crops as well as on the health of farmers and agricultural labourers and also to estimate the efficiency of cotton and paddy farms using different inputs including pesticides. The farmers and agricultural labourersengaged in the cultivation of cotton and paddy crops were randomly selected from two villages i.e. Laleana and Rayia respectively. The primary data was collected from 120 farmers and 80 agricultural labourers through structure schedules. The rate of return of pesticides for the cotton crop for large farmers (Rs. 13.40) was less than the medium farmers (Rs. 14.31) and the small farmers (Rs. 15.44). It was the highest for small farmers (Rs. 15.44) showing that it decreases with the increase in the expenditure on pesticides. Likewise, for paddy, the rate of return was less for large farmers (Rs. 18.56) as they incurred more on pesticides while the highest for small farmers (Rs. 22.67). Regarding the impact of different inputs used for returns of cotton, pesticides were significant and positive input while for paddy; labour was significant and positive variable. Usage of pesticides had a harmful effect on the health of farmers and agricultural labourers indicating that those were using manual backup sprayer face many problems. The proper awareness to farmers should be provided through various channels. ? 2017, [International Journal of Ecological Economics & Statistics].
Identification of novel translocation between short arm of chromosome 4 and long arm of chromosome 6 in an infertile man using Interphase Chromosome Profiling (ICP)
(Blackwell Publishing Ltd, 2018) Kaul, S.; Kaur, H.; Vats, S.K.S.; Chawla, J.; Jindal, R.; Khetarpal, P.
Conventional cytogenetics has always been a favourite to detect chromosomal aberrations. Carriers of chromosomal translocation are often phenotypically normal but are infertile. Couples are often advised to go for karyotyping, but culture failure or improper metaphase spread with poor banding often makes the analysis difficult. We report here a novel translocation between short arm of chromosome 4 and long arm of chromosome 6 in an infertile man using an advanced molecular cytogenetic technique of Interphase Chromosome Profiling (ICP). ? 2018 Blackwell Verlag GmbH
Socio-economic development of Uttar Pradesh: an empirical analysis
(Indian Society for Education and Environment, 2017) Kaur, H.; Mishra, P. K.
Background/Objectives: Since the concepts of social and economic development of a nation/region/state is crucial for the development of human resources, the objective of this paper is to examine the socio- economic development of Uttar Pradesh in the post-reform period. Methods/Statistical analysis: The socio-economic profile of Uttar Pradesh has been examined by calculating decadal growth rates, compound annual growth rates, and by constructing appropriate time series plots. Specifically, the economic profile of the state has been presented with the help of real gross state domestic product at factor cost. And, the social aspect of development has been examined with the help of government expenditure on education and health as percentage of gross state domestic product. Findings: The findings of the study reveal a low level of human development, and consequential low level of growth of the economy of Uttar Pradesh. It is uniquely observed that the average performance of all economic as well as social sectors in the state has declined during 2012 and 2015. This observation is sufficient to justify the persistency of unemployment, poverty and inequality in the state. Improvements/Applications: Appropriate policy initiatives are warranted to address the problems of socio-economic backwardness of Uttar Pradesh. Specifically, it is essential to focus on the development of the masses at the bottom of the pyramid.
