Effort Monitoring and Tracking System
T. Rajesh Kumar,Dama Anand,G. Rama Krishna Srinivas,Debnath Bhattacharyya,Hye-jin Kim 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.12
Prime Leading organizations will use the web portal for effort monitoring and tracking. This portal is used to store and analyze the employee effort from various R&D departments. This portal provides a front end environment for employees/management of an organization to keep a track of his/her effort. It is also expected to use SharePoint advanced features such as content management, alerts, information management policies, collaboration features, reporting, and analytics services.
Study on acquisition of bacterial antibiotic resistance determinants in poultry litter
Dhanarani, T. Sridevi,Shankar, C.,Park, J.,Dexilin, M.,Kumar, R. Rajesh,Thamaraiselvi, K. Elsevier 2009 Poultry science Vol.88 No.7
<P>Antibiotic resistance and the mode of transmission were investigated in bacteria isolated from poultry litter. Total aerobic heterotrophic bacteria were screened and identified for their resistance to different antibiotics such as ampicillin, streptomycin, erythromycin, tetracycline, chloramphenicol, kanamycin, tobramycin, and rifampicin. The distribution of bacteria found in the litter was Staphylococcus (29.1%), which was the predominant group, followed by Streptococcus (25%), Micrococcus (20.8%), Escherichia coli (12.5%), Salmonella (8.3%), and Aeromonas (4.1%). Fifty percent of these isolates were susceptible to ampicillin, 57% to erythromycin, 25% to tetracycline, 4% to chloramphenicol, 40% to kanamycin, 75% to streptomycin, 54% to tobramycin, and 4% to rifampicin. Three randomly selected isolates representing Staphylococcus, Streptococcus, and Micrococcus were examined for plasmids, and plasmid-curing and plasmid-induced transformation studies were conducted. Streptococcus and Micrococcus harbored a plasmid of 4.2 and 5.1 kb, respectively, whereas Staphylococcus did not harbor any plasmids. Plasmids were cured in Streptococcus and Micrococcus at a concentration of 75 and 100 microg/ mL of acridine orange, respectively, and transformation of 4.2- and 5.1-kb plasmids isolated from the Streptococcus and Micrococcus to plasmid-free E. coli DH5alpha strain was possible. In conjugation experiments, the antibiotic resistance profiles of transconjugant cells were found to be the same as the donors with the exception of Staphylococcus. The results of this study suggest that transformation and conjugation could be an important mechanism for horizontal gene transfer between bacteria in poultry litter. An understanding of the mechanism and magnitude of resistance gene transfer may provide a strategy to reduce the potential for dissemination of these genes.</P>

In this work, the technique of spin arc welding has been used to weld HSLA steel of grade 15CDV6. Experiments wereperformed according to the L9 Taguchi matrix using current, travel speed, wire feed rate, and spin rotation speed as inputparameters. The quality of the weld was analysed by measuring the bead geometry and microhardness. The Whale OptimizationAlgorithm (WOA) was used to identify the optimized welding parameters. The optimised parameters were identifiedthrough WOA as follows: current 230 A, voltage 24 V, travel speed 720 mm/min, and spin rotation speed 1500 rpm. Thepost-weld heat treatment (PWHT) was performed on the optimised welded sample to enhance the weld properties. Themicrohardness was increased by 79% after PWHT. Ferrite content was found to have reduced after welding and PWHT thegrain size and structure of the BM, HAZ, and WM were analysed by EBSD technique. The decrease in ferrite content hada significant effect on the microhardness. The Energy Dispersive Spectroscopy results showed the presence of Vanadiumcarbide (VC) precipitates which helped in increasing the microhardness.
A note on vertex pair sum $k$-zero ring labeling
Antony Sanoj Jerome,K.R. Santhosh Kumar,T.J. Rajesh Kumar 한국전산응용수학회 2024 Journal of applied mathematics & informatics Vol.42 No.2
Let $G=(V,E)$ be a graph with $p$-vertices and $q$-edges and let $R^{\circ}$ be a finite zero ring of order $n$. An injective function $f:V(G)\to \{r_1,r_2,\ldots,r_k\}$, where $r_i\in R^\circ$ is called vertex pair sum $k$-zero ring labeling, if it is possible to label the vertices $x\in V$ with distinct labels from $R^{\circ}$ such that each edge $e=uv$ is labeled with $f(e=uv)=[f(u)+f(v)] \pmod n$ and the edge labels are distinct. A graph admits such labeling is called vertex pair sum $k$-zero ring graph. The minimum value of positive integer $k$ for a graph $G$ which admits a vertex pair sum $k$-zero ring labeling is called the vertex pair sum $k$-zero ring index denoted by $\psi_{pz}(G)$. In this paper, we defined the vertex pair sum $k$-zero ring labeling and applied to some graphs.
Development of Symmetrical Fault Detection During Power Swing Based on Entropy
Devi R.,Kirthika A.,Divya Priyadharshini M.,Ladha Akash,Anju A.,Rajesh Kumar T.,Ganesh Prabhu S.,Varghese Lijo Jacob,Santhosh P. 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.3
This paper proposes the new technique for detecting symmetrical faults occurred during power swing. The proposed technique is simulated for the protection of two machine system, distribution system with distributed generation and WSCC 9-bus system in Matlab. Symmetrical fault detection during power swing is a critical issue. Hence, in this paper, modifi ed weighted wavelet packet entropy technique is proposed to detect symmetrical fault during power swing. This entropy criterion is applied to wavelet packet coeffi cients to enhance the energy of fault signals and to reduce the vector size of the wavelet packet transform coeffi cients. This technique provides better results irrespective of various fault locations, fault inception angle and power swing frequencies. This technique is compared with conventional scheme and the results are tabulated. Moreover, this technique is also able to detect asymmetrical faults with high impedance during power swing. Mathematical derivation support system performance through simulation.
