Mohd Rashid,Sanjay Kumar Kotwal,M. A. Malik,Maninder Singh
Veterinary World , 2013, DOI: 10.5455/vetworld.2013.139-142
Abstract: Aim: The aim of this study was to assess the hygienic quality of foods of animal origin. Thus samples from foods of animal origin, viz. mutton, chicken meat, milk and milk products were processed. Materials and Methods: Two hundred samples from foods of animal origin viz., mutton, chicken meat, milk and milk products were processed for isolation of Escherichia coli. The isolates were got serotyped and also subjected to detection of virulence genes viz., stx1, stx2, eaeA and hlyA by PCR.The isolates were also tested against commonly used antibiotics. Results: The prevalence of E. coli was 30% in mutton, 40% in chicken meat, 33.96% in milk and14.89% in milk products samples. All the 60 isolates of E. coli were grouped into 24 serogroups with O60 and O123dominant strains (8.33%) followed by O22 (6.66%). The PCR detected 21(10.5%) of samples possessing stx1, 14(7%) stx2, 3(1.5%) both stx1 and stx2, 16(8%), eaeA and 4(2%) EHEC-hlyA gene. However, the prevalence of Shiga toxin producing E. coli (STEC) was 20% in mutton, 30% in chicken meat, 16.98% in milk and 8.51% in milk products. Whereas the prevalence of enteropathogenic E. coli (EPEC) was 2%, in mutton, 4% in chicken meat, 7.54% in milk and 2.12% in milk products samples. The 4 isolates O60, O101, O131 and one untypeable strain possessed the EHEC-hlyA gene. 22 of 50 (44%) of isolates from meat, milk and milk products showed multidrug resistance to four or more antimicrobial comprising ten of 25 (40%) isolates from chicken meat samples and 12 of 25(48%) from milk and milk products were multidrug resistance to four or more antimicrobial. Conclusions: It is concluded that partial cooked or raw milk, meat and their products prepared under unhygienic conditions may not be directly consumed as they may be carrying the pathogenic microbes.

Biometric Recognition for Pet Animal  [PDF]
Santosh Kumar, Sanjay Kumar Singh
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.75044
Abstract:

Missing, swapping, false insurance claims and reallocation of pet animals (dog) are global problems throughout the world and research done to solve this problem is minimal. Traditional biometrics and non-biometrics methods have their own boundaries and they fail to provide competent level of security to pet animal (dog). The work on animal identification based on their phenotype appearance (coat patterns) has been an active research area in recent years and automatic face recognition for dog is not reported in the literature. Dog identification needs innovative research to protect the pet animal. Therefore it is imperative to initiate research, so that future face recognition algorithm will be able to solve this important problem for identification of pet animal (like dog, cat). In this paper an attempt has been made to minimize the above mentioned problems by biometrics face recognition of dog. The contributions of this research are: 1) implementation of an existing biometrics algorithm which mitigates the effects of covariates for dogs; 2) proposed fusion based method for recognition of pet animal with 94.86% accuracy. Thus in this paper, we have tried to demonstrate that face recognition of dog can be used to recognize the dog efficiently.

Some Common Fixed Point Theorems in Menger Space  [PDF]
Sanjay Kumar, Asha Rani
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.33038
Abstract: This paper consists four sections. First section is central to the text. In second section, we generalize the results of Kohli and Vashistha [1] for pairs of mappings using weakly compatible maps. Third section deals the results for pair of weakly compatible maps along with property (E.A.) using different types of control functions, which generalize the results of Kohli and Vashistha [1] and Kubiaczyk and Sharma [2]. Fourth section is concerned with results for occasionally weakly compatible maps and generalizes, extends and unifies several well known comparable results in literature.
On the Rate of Convergence of Some New Modified Iterative Schemes  [PDF]
Renu Chugh, Sanjay Kumar
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.34037
Abstract:

In this article, following Bizare and Amriteimoori [1] and B. Parsad and R. Sahni [2], we modify Ishikawa, Agarwal et al., Noor, SP iterative schemes and compare the rate of convergence of Ishikawa, Agarwal et al., Noor, SP and new modified Ishikawa, Agarwal et al., Noor, SP iterative schemes not only for particular fixed value of an,bn,rn but also for varying the value of an,bn,rn. With the help of two numerical examples, we compare the converging step.

Reliability Analysis of a Powerloom Plant Using Interval Valued Intuitionistic Fuzzy Sets  [PDF]
Sanjay Kumar Tyagi
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.513193
Abstract:

In this paper, we investigate the reliability analysis of a powerloom plant by using interval valued intuitionistic fuzzy sets (IVIFS). Herein, we modeled a powerloom plant as a gracefully degradable system having two units A(n) and B(m) connected in series. The reliability ofncomponents of unitAandmcomponents of unitBis assumed to be an IVIFS defined over the universe of discourse [0, 1]. Thus, the reliability of the system obtained is an IVIFS that covers the inherited uncertainty in data collection and reliability evaluation of a powerloom plant.

Coupled Fixed Point for (α, Ψ)-Contractive in Partially Ordered Metric Spaces Using Compatible Mappings  [PDF]
  Preeti, Sanjay Kumar
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.68130
Abstract: In this paper, first we introduce notions of (α, Ψ)-contractive and (α)-admissible for a pair of map and prove a coupled coincidence point theorem for compatible mappings using these notions. Our work extends and generalizes the results of Mursaleen et al. [1]. At the end, we will provide an example in support of our result.
Aperture Coupled Microstrip Antenna for Dual-Band  [PDF]
Rajesh Kumar Vishwakarma, Sanjay Tiwari
Wireless Engineering and Technology (WET) , 2011, DOI: 10.4236/wet.2011.22013
Abstract: This paper presents air gap aperture coupled microstrip antenna for dual-band operation over the frequency range of (2.9 to 6.0 GHz). This antenna differs from any other microstrip antenna with their feeding structure of the radiating patch element. Input signal couples to the radiating patch trough the aperture that exists on the ground plane of microstrip feed line. The dual-band achieved by variation of air gap [2 mm to 6 mm] between single patch antenna and aper-ture coupled microstrip antenna. The main advantage of this type antenna is increased the bandwidth of the antenna as compared to a single layered patch antenna. The two resonant frequencies can vary over a wide frequency range and the input impedance is easily matched for both frequencies. The obtain ratios of resonance frequencies are variable from 2.1 GHz to 1.1 GHz with increasing the air gap between single patch and aperture coupled microstrip antenna. The measured return loss [–14 dB] exhibits an impedance bandwidth of 35%. The input impedance and VSWR return loss have been measured with the help of Network analyzer.

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.713183
Abstract: The research and innovation in the field of computer and technology has made significant contribution for the development of new pedagogical strategies in all levels of education. The use of digital tools like animation has changed the way of providing education, especially in primary school level, adding an element of entertainment to the process of teaching and learning. It is assumed that the use of animated instructional material can help to present a complex concept in a simple form, create more interest about the subject, motivate the pupil for better learning, increase the accuracy of the message and play a crucial role in improving the students’ academic performance. Against this background, the present paper attempts to assess the efficacy of animation on different subjects in primary education. Here, in the study, an experiment has been conducted using animation to teach three subjects Mathematics, Language and Science; and students’ performance was compared and analyzed using fuzzy statistical tools.
Fuzzy Fault Tree Analysis for Fault Diagnosis of Cannula Fault in Power Transformer  [PDF]
Sanjay Kumar Tyagi, Diwakar Pandey, Vinesh Kumar
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.211188
Abstract: Being one of the most expensive components of an electrical power plant, the failures of a power transformer can result in serious power system issues. So fault diagnosis for power transformer is highly important to ensure an uninterrupted power supply. Due to information transmission mistakes as well as arisen errors while processing data in surveying and monitoring state information of transformer, uncertain and incomplete information may be produced. Based on these points, this paper presents an intelligent fault diagnosis method of power transformer using fuzzy fault tree analysis (FTA) and beta distribution for failure possibility estimation. By using the technique we proposed herein, the continuous attribute values are transformed into the fuzzy numbers to give a realistic estimate of failure possibility of a basic event in FTA. Further, it explains a new approach based on Euclidean distance between fuzzy numbers, to rank the basic events in accordance with their Fuzzy Importance Index.
