The proposed method accounts for a convolutional layer capable of automatically learning correlation between neighbouring pixels. In the current form, Convolutional Neural Network (CNN) will learn features based on an image's content instead of the structural features of the image. The layer is particularly designed to subdue an image's content and robustly learn the sensor pattern noise features (usually inherited from image processing in a camera) as well as the statistical properties of images. The paper was assessed on latest natural and computer generated images, and it was concluded that it performs better than the current state of the art methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20forensics" title="image forensics">image forensics</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20graphics" title=" computer graphics"> computer graphics</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20networks" title=" convolutional neural networks"> convolutional neural networks</a> </p> <a href="https://publications.waset.org/abstracts/95266/classification-of-computer-generated-images-from-photographic-images-using-convolutional-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95266.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Voltage Stability Assessment and Enhancement Using STATCOM -A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Chawla">Puneet Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Balwinder%20Singh"> Balwinder Singh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, increased attention has been devoted to the voltage instability phenomenon in power systems. Many techniques have been proposed in the literature for evaluating and predicting voltage stability using steady state analysis methods. In this paper, P-V and Q-V curves have been generated for a 57 bus Patiala Rajpura circle of India. The power-flow program is developed in MATLAB using Newton-Raphson method. Using Q-V curves, the weakest bus of the power system and the maximum reactive power change permissible on that bus is calculated. STATCOMs are placed on the weakest bus to improve the voltage and hence voltage stability and also the power transmission capability of the line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability" title="voltage stability">voltage stability</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20power" title=" reactive power"> reactive power</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20flow" title=" power flow"> power flow</a>, <a href="https://publications.waset.org/abstracts/search?q=weakest%20bus" title=" weakest bus"> weakest bus</a>, <a href="https://publications.waset.org/abstracts/search?q=STATCOM" title=" STATCOM"> STATCOM</a> </p> <a href="https://publications.waset.org/abstracts/3097/voltage-stability-assessment-and-enhancement-using-statcom-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3097.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">515</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Resource Management Framework in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gagandeep%20Kaur">Gagandeep Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonal%20Chawla"> Sonal Chawla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a Cloud Computing environment, resource provisioning, resource allocation and resource scheduling is the most complex issues these days.

With the increase of population in cities, pedestrian traffic is increasing day by day. Pedestrian safety has become a matter of concern for the Traffic Engineers. Pedestrian comfort is primary important for the Engineers who design different pedestrian facilities. Pedestrian comfort and safety can be measured in terms of different level of service (LOS) of the facilities. In this study video data on pedestrian movement have been collected from different railway foot over bridges (FOB) in India. The level of service of those facilities has been analyzed. A cellular automata based model has been formulated to mimic the route choice behaviour of the pedestrians on the foot over bridges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellular%20automata%20model" title="cellular automata model">cellular automata model</a>, <a href="https://publications.waset.org/abstracts/search?q=foot%20over%20bridge" title=" foot over bridge"> foot over bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20service" title=" level of service"> level of service</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian" title=" pedestrian"> pedestrian</a> </p> <a href="https://publications.waset.org/abstracts/54466/empirical-study-and-modelling-of-three-dimensional-pedestrian-flow-in-railway-foot-over-bridge-stair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54466.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Behavior of Reinforced Concrete Structures Subjected to Multiple Floor Fire Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Narayana">Suresh Narayana</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Akkannavar"> Chaitanya Akkannavar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assessment of behavior of reinforced concrete structures subjected to fire load, and its behavior for the multi-floor fire have been presented in this paper.

The modified Korteweg-de Vries (m-KdV) equation using reductive perturbation method is derived. It is found that for the selected set of parameters, the system supports rarefactive double layers depending upon the value of nonthermal parameters. It is also found that the magnetization affects only the width of the double layer. For a given set of parameter values, increases in the magnetization and the obliqueness angle (θ) between wave vector and magnetic field, affect the width of the double layers, however the amplitude of the double layers have no effect. An increase in the values of nonthermal parameter decreases the amplitude of the rarefactive double layer. The effect of the ion temperature ratio on the amplitude and width of the double layers are also discussed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ion-acoustic%20double%20layers" title="ion-acoustic double layers">ion-acoustic double layers</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetized%20electronegative%20plasma" title=" magnetized electronegative plasma"> magnetized electronegative plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=reductive%20perturbation%20method" title=" reductive perturbation method"> reductive perturbation method</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20modified%20Korteweg-de%20Vries%20%28KdV%29%20equation" title=" the modified Korteweg-de Vries (KdV) equation"> the modified Korteweg-de Vries (KdV) equation</a> </p> <a href="https://publications.waset.org/abstracts/48843/ion-acoustic-double-layers-in-a-non-thermal-electronegative-magnetized-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48843.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">610</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Loss Minimization by Distributed Generation Allocation in Radial Distribution System Using Crow Search Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Nageswara%20Rao">M.

The two main important part of this study first is to find optimal allocation and second is optimum size of DG. The locations of DGs are identified by Analytical expressions and crow search algorithm has been employed to determine the optimum size of DG. In this study, the DG has been placed on single and multiple allocations.CSA is a meta-heuristic algorithm inspired by the intelligent behavior of the crows. Crows stores their excess food in different locations and memorizes those locations to retrieve it when it is needed. They follow each other to do thievery to obtain better food source. This analysis is tested on IEEE 33 bus and IEEE 69 bus under MATLAB environment and the results are compared with existing methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20expression" title="analytical expression">analytical expression</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation" title=" distributed generation"> distributed generation</a>, <a href="https://publications.waset.org/abstracts/search?q=crow%20search%20algorithm" title=" crow search algorithm"> crow search algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20loss" title=" power loss"> power loss</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20profile" title=" voltage profile"> voltage profile</a> </p> <a href="https://publications.waset.org/abstracts/104210/loss-minimization-by-distributed-generation-allocation-in-radial-distribution-system-using-crow-search-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104210.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">235</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Assessment of Mammary Gland Immunity and Therapeutic Potential of Topical Herbal Gel against Bovine Subclinical Mastitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukesh%20N.%20Kher">Mukesh N.

The response to treatment was evaluated by enumerating somatic cell count (SCC), determining total bacterial count and studying the expression of different cytokines like (interleukin 6, 8, 12, GMCSF, interferon–γ and TNF‑α). The pre‑ and post‑treatment SCC in mastitic quarters did not differ statistically-significantly. However, total bacterial count declined significantly from day 0 onwards in both the breeds. Significant differences (P < 0.01) were observed in all types of cytokines production on day 0, 5, and 21 post last treatments in both the breeds. The comparison of cytokine expression profiles between crossbred and Gir cattle affirmed a significant difference in expression of IL-6 and TNF-α. The topical herbal gel showed immunomodulatory and antimicrobial activities in subclinical mastitis, and therefore the work supports its use as substitute herbal therapy against subclinical mastitis in bovines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=immunomodulation" title=" immunomodulation"> immunomodulation</a>, <a href="https://publications.waset.org/abstracts/search?q=herbal%20gel" title=" herbal gel"> herbal gel</a>, <a href="https://publications.waset.org/abstracts/search?q=subclinical%20mastitis" title=" subclinical mastitis"> subclinical mastitis</a> </p> <a href="https://publications.waset.org/abstracts/66343/assessment-of-mammary-gland-immunity-and-therapeutic-potential-of-topical-herbal-gel-against-bovine-subclinical-mastitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66343.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Tribological Performance of Polymer Syntactic Foams in Low-Speed Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Narasimha%20Rao">R.

At Low speeds, the wear rate is sensitive to the sliding speeds and other tribological parameters like applied load and the sliding distance. In the present study, the tribological performance of the polymer-based syntactic foams was reported based on the experiments conducted on a pin-on-disc tribometer. The syntactic foams were manufactured with epoxy as the matrix and the cenospheres obtained from the thermal powerplants as the reinforcement. The experiments were conducted at a sliding speed of the 1 m/s. The applied load was varied from 1 kg to 5 kg up to a sliding distance of 3000 m. The wear rate increased with the sliding distance at lower loads. The trend was reversed at higher loads of 5kg. This may be due to the high plastic deformation at the initial stages when higher loads were applied. This was evident with the higher friction constants for the higher loads. The adhesive wear was found to be predominant for lower loads, while the abrasive wear tracks can be seen in micrographs of samples tested under higher loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sliding%20speed" title="sliding speed">sliding speed</a>, <a href="https://publications.waset.org/abstracts/search?q=syntactic%20foams" title=" syntactic foams"> syntactic foams</a>, <a href="https://publications.waset.org/abstracts/search?q=tribological%20performance" title=" tribological performance"> tribological performance</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20rate" title=" wear rate"> wear rate</a> </p> <a href="https://publications.waset.org/abstracts/169677/tribological-performance-of-polymer-syntactic-foams-in-low-speed-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Characterization of Nanostructured and Conventional TiAlN and AlCrN Coated ASTM-SA213-T-11 Boiler Steel </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vikas%20Chawla">Vikas Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Buta%20Singh%20Sidhu"> Buta Singh Sidhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Amita%20Rani"> Amita Rani</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Handa"> Amit Handa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of the present work is microstructural and mechanical characterization of the conventional and nanostructured TiAlN and AlCrN coatings deposited on T-11 boiler steel. In case of conventional coatings, Al-Cr and Ti-Al metallic powders were deposited using plasma spray process followed by gas nitriding of the surface which was done in the lab with optimized parameters after conducting several trials on plasma-sprayed coated specimens. The physical vapor deposition process (PAPVD) was employed for depositing nanostructured TiAlN and AlCrN coatings. The field emission scanning electron microscopy (FE-SEM) with energy dispersive X-ray analysis (EDAX) attachment, X-ray diffraction (XRD) analysis, atomic force microscopy (AFM) analysis and the X-Ray mapping analysis techniques have been used to study surface and cross-sectional morphology of the coatings. The surface roughness and micro-hardness were also measured. A good adhesion of the conventional thick TiAlN and AlCrN coatings was found. The coatings under study are recommended for the applications to super-heater and re-heater tubes of the boilers based upon the outcomes of the research work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanostructure" title="nanostructure">nanostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20vapour%20deposition" title=" physical vapour deposition"> physical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=oxides" title=" oxides"> oxides</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20microscopy" title=" electron microscopy"> electron microscopy</a> </p> <a href="https://publications.waset.org/abstracts/112764/characterization-of-nanostructured-and-conventional-tialn-and-alcrn-coated-astm-sa213-t-11-boiler-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112764.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Modeling and Analysis of DFIG Based Wind Power System Using Instantaneous Power Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaimala%20Ghambir">Jaimala Ghambir</a>, <a href="https://publications.waset.org/abstracts/search?q=Tilak%20Thakur"> Tilak Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Chawla"> Puneet Chawla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As per the statistical data, the Doubly-fed Induction Generator (DFIG) based wind turbine with variable speed and variable pitch control is the most common wind turbine in the growing wind market. This machine is usually used on the grid connected wind energy conversion system to satisfy grid code requirements such as grid stability, fault ride through (FRT), power quality improvement, grid synchronization and power control etc. Though the requirements are not fulfilled directly by the machine, the control strategy is used in both the stator as well as rotor side along with power electronic converters to fulfil the requirements stated above. To satisfy the grid code requirements of wind turbine, usually grid side converter is playing a major role. So in order to improve the operation capacity of wind turbine under critical situation, the intensive study of both machine side converter control and grid side converter control is necessary In this paper DFIG is modeled using power components as variables and the performance of the DFIG system is analysed under grid voltage fluctuations. The voltage fluctuations are made by lowering and raising the voltage values in the utility grid intentionally for the purpose of simulation keeping in view of different grid disturbances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFIG" title="DFIG">DFIG</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20modeling" title=" dynamic modeling"> dynamic modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=DPC" title=" DPC"> DPC</a>, <a href="https://publications.waset.org/abstracts/search?q=sag" title=" sag"> sag</a>, <a href="https://publications.waset.org/abstracts/search?q=swell" title=" swell"> swell</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20fluctuations" title=" voltage fluctuations"> voltage fluctuations</a>, <a href="https://publications.waset.org/abstracts/search?q=FRT" title=" FRT"> FRT</a> </p> <a href="https://publications.waset.org/abstracts/33460/modeling-and-analysis-of-dfig-based-wind-power-system-using-instantaneous-power-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33460.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">462</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Analysis of Operating Speed on Four-Lane Divided Highways under Mixed Traffic Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Varma">Chaitanya Varma</a>, <a href="https://publications.waset.org/abstracts/search?q=Arpan%20Mehar"> Arpan Mehar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study demonstrates the procedure to analyse speed data collected on various four-lane divided sections in India. Field data for the study was collected at different straight and curved sections on rural highways with the help of radar speed gun and video camera. The data collected at the sections were analysed and parameters pertain to speed distributions were estimated. The different statistical distribution was analysed on vehicle type speed data and for mixed traffic speed data. It was found that vehicle type speed data was either follows the normal distribution or Log-normal distribution, whereas the mixed traffic speed data follows more than one type of statistical distribution. The most common fit observed on mixed traffic speed data were Beta distribution and Weibull distribution. The separate operating speed model based on traffic and roadway geometric parameters were proposed in the present study. The operating speed model with traffic parameters and curve geometry parameters were established. Two different operating speed models were proposed with variables 1/R and Ln(R) and were found to be realistic with a different range of curve radius. The models developed in the present study are simple and realistic and can be used for forecasting operating speed on four-lane highways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=highway" title="highway">highway</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20traffic%20flow" title=" mixed traffic flow"> mixed traffic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20speed" title=" operating speed"> operating speed</a> </p> <a href="https://publications.waset.org/abstracts/33813/analysis-of-operating-speed-on-four-lane-divided-highways-under-mixed-traffic-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33813.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">460</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Network and Sentiment Analysis of U.S. Congressional Tweets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Kanakamedala">Chaitanya Kanakamedala</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansa%20Pradhan"> Hansa Pradhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Carter%20Gilbert"> Carter Gilbert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social media platforms, such as Twitter, are excellent datasets for understanding human interactions and sentiments. This report explores social dynamics among US Congressional members through a network analysis applied to a dataset of tweets spanning 2008 to 2017 from the ’US Congressional Tweets Dataset’. In this report, we preform network analysis where connections between users (edges) are established based on a similarity threshold: two tweets are connected if the tweets they post are similar. By utilizing the Natural Language Toolkit (NLTK) and NetworkX, we quantified tweet similarity and constructed a graph comprising various interconnected components. Each component represents a cluster of users with closely aligned content. We then preform sentiment analysis on each cluster to explore the prevalent emotions and opinions within these groups. Our findings reveal that despite the initial expectation of distinct ideological divisions typically aligning with party lines, the analysis exposed a high degree of topical convergence across tweets from different political affiliations. The analysis preformed in this report not only highlights the potential of social media as a tool for political communication but also suggests a complex layer of interaction that transcends traditional partisan boundaries, reflecting a complicated landscape of politics in the digital age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title="natural language processing">natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=sentiment%20analysis" title=" sentiment analysis"> sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=centrality%20analysis" title=" centrality analysis"> centrality analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=topic%20modeling" title=" topic modeling"> topic modeling</a> </p> <a href="https://publications.waset.org/abstracts/189004/network-and-sentiment-analysis-of-us-congressional-tweets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189004.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">33</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Enhancement of Hydrophobicity of Thermally Evaporated Bi Thin Films by Oblique Angle Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravish%20K.%20Jain">Ravish K.

Bi thin films were studied for their hydrophobic nature. The effects of oblique angle deposition on structural, surface morphology, electrical and wettability properties of Bi thin films have been studied and a comparison of these physical properties of normally deposited and obliquely deposited Bi films has been carried out in this study. X-ray diffraction studies found that films have highly oriented hexagonal crystal structure and crystallite size is smaller for obliquely deposited (70 nm) film as compared to that of the normally deposited film (111 nm). Raman spectra of the films consist of peaks corresponding to E_g and A_1g first-order Raman modes of bismuth. The atomic force and scanning electron microscopy studies show that the surface roughness of obliquely deposited film is higher as compared to that of normally deposited film. Contact angle measurements revealed that both films are strongly hydrophobic in nature with the contact angles of 105ᵒ and 119ᵒ for normally and obliquely deposited films respectively. Oblique angle deposition enhances the hydrophobicity of the film. The electrical conductivity of the film is significantly reduced by oblique angle deposition. The activation energies for electrical conduction were determined by four-probe measurements and are 0.016 eV and 0.018 eV for normally and obliquely deposited films respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi%20thin%20films" title="bi thin films">bi thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobicity" title=" hydrophobicity"> hydrophobicity</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20angle%20deposition" title=" oblique angle deposition"> oblique angle deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20morphology" title=" surface morphology"> surface morphology</a> </p> <a href="https://publications.waset.org/abstracts/97326/enhancement-of-hydrophobicity-of-thermally-evaporated-bi-thin-films-by-oblique-angle-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97326.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">259</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Mature Cystic Teratomas of Ovary: A Series of 19 Cases with Rare Malignant Transformation in Three</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parveen%20Kundu">Parveen Kundu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitika%20Chawla"> Nitika Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruchi%20Agarwal"> Ruchi Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Swaran%20Kaur"> Swaran Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mature cystic teratoma is a benign, most common tumor of the ovary occurring mostly in young and middle-aged females. This study consists of 19 cases of mature cystic teratomas which were received in the Department Of Pathology over a period of two years. There were malignant transformations observed in three cases, which makes it very important for pathologists to thoroughly examine the entire specimen of mature cystic teratomas. Material and Methods: Nineteen reported cases of mature cystic teratomas were received in Deptt. Of Pathology, BPS GMC Khanpur Kalan, Sonepat, over a two-year period from November 2020 to October 2022 and reviewed retrospectively. Data regarding age, size, laterality, gross, morphological features, and surgery performed were retrieved from pathological archives. Results: In our study, the most common age of presentation was the 20-40 year age group. The most common presenting complaint was fullness in the abdomen or abdominal distension. Four out of 19 cases studied cases presented with bilateral ovarian cysts. Tumor size ranged from 6 to 20 cm in diameter. In seven cases, cysts were greater than or equal to 10 cm in diameter. Three cases showed malignant transformation. Conclusion: It is very important to thoroughly examine the contralateral ovary to rule out bilateral presentation. A furthermost thorough examination is advised in tumors of size >10 cm and in tumors with solid areas to rule out any malignant transformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teratoma" title="teratoma">teratoma</a>, <a href="https://publications.waset.org/abstracts/search?q=ovary" title=" ovary"> ovary</a>, <a href="https://publications.waset.org/abstracts/search?q=malignant" title=" malignant"> malignant</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a> </p> <a href="https://publications.waset.org/abstracts/169478/mature-cystic-teratomas-of-ovary-a-series-of-19-cases-with-rare-malignant-transformation-in-three" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169478.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Multivariate Analysis of Causes of Death among Hepatocellular Carcinoma Patients: A Seer-Based Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peri%20Harish%20Kumar">Peri Harish Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sai%20Sharan%20Dwarka"> Sai Sharan Dwarka</a>, <a href="https://publications.waset.org/abstracts/search?q=Tajbinder%20Singh%20Bains"> Tajbinder Singh Bains</a>, <a href="https://publications.waset.org/abstracts/search?q=Suneet%20John%20Joseph"> Suneet John Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Kiran"> Chaitanya Kiran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sambhu%20Dutta"> Sambhu Dutta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Makram"> Sarah Makram</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sayed%20Zaazouee"> Mohamed Sayed Zaazouee</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Ahmed%20Elshanbary"> Alaa Ahmed Elshanbary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To identify cancer and non-cancer causes of death in hepatocellular carcinoma (HCC) patients over different time periods after diagnosis and to compare the mortality risk of each cause in HCC patients with the general population. Methods: In this retrospective cohort study, data of 67,637 HCC patients from 1975 to 2016 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. We investigated the association between different causes of death and the following variables: age, race, tumor stage at diagnosis, and treatment (surgery, chemotherapy, and radiotherapy); each according to the periods of <1 year, 1-5 years, 5-10 years, and >10 years following the diagnosis. Standardized mortality ratios (SMRs) and their 95% confidence intervals (CIs) were calculated for cancer and non-cancer deaths in each of the mentioned periods following diagnosis. Results: Data of 67,637 patients, of whom 50,571 patients died during the follow-up period, were analyzed. Most deaths were due to HCC itself (35,535, 70.3%), followed by other cancers (3,983, 7.9%). Common causes of non-cancer mortality included infectious and parasitic diseases including HIV (2,823 patients, SMR=105.68, 95% CI: 101.82-109.65), chronic liver disease (2,719 patients, SMR=76.56, 95% CI: 73.71,79.5), and heart diseases (1,265 patients, SMR=2.26, 95% CI: 2.14-2.39), with higher mortality risk in HCC patients than in the general population. Conclusion: Cancers stand for most deaths in patients with HCC. Besides, infectious, and parasitic diseases including HIV represent the commonest non-cancer cause of mortality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatocellular%20carcinoma" title="hepatocellular carcinoma">hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=seer" title=" seer"> seer</a>, <a href="https://publications.waset.org/abstracts/search?q=causes%20of%20death" title=" causes of death"> causes of death</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/165052/multivariate-analysis-of-causes-of-death-among-hepatocellular-carcinoma-patients-a-seer-based-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Modeling of Full Range Flow Boiling Phenomenon in 23m Long Vertical Steam Generator Tube</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20R.%20Mali">Chaitanya R.

For this purpose, the methodology has been developed which covers all the flow boiling regimes to model full range flow boiling phenomenon. In this methodology, the vertical tube is divided into four sections based on vapor fraction value at the end of each section. Different modeling strategies have been applied to the different sections of the vertical tube. Computational fluid dynamics simulations have been performed on a vertical SG tube of 0.0126 m inner diameter and 23 m length. The thermal hydraulic parameters such as vapor fraction, liquid temperature, heat transfer coefficient, pressure drop, heat flux distribution have been analyzed for different designed heat duties (1.1 MW (20%) to 3.3 MW (60%)) and flow conditions (10 % to 80 %). The sensitivity of different boiling parameters such as bubble departure diameter, nucleation site density, bubble departure frequency on the thermal hydraulic parameters was also studied. Flow instability has been observed at 20 % designed heat duty and 20 % flow conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20hydraulics" title="thermal hydraulics">thermal hydraulics</a>, <a href="https://publications.waset.org/abstracts/search?q=boiling" title=" boiling"> boiling</a>, <a href="https://publications.waset.org/abstracts/search?q=vapor%20fraction" title=" vapor fraction"> vapor fraction</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/106204/modeling-of-full-range-flow-boiling-phenomenon-in-23m-long-vertical-steam-generator-tube" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106204.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> An Integrated Approach for Optimal Selection of Machining Parameters in Laser Micro-Machining Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Gopala%20Krishna">A.

While machining, Because of the intense heat generated, A layer gets formed on the work piece surface which is called recast layer and this layer is detrimental to the surface quality of the component. The recast layer needs to be as small as possible for precise applications. Therefore, The height of recast layer and the depth of groove which are conflicting in nature were considered as the significant manufacturing criteria, Which determines the pursuit of a machining process obtained in LMM of Al7075/10%SiCp composite. The present work formulates the depth of groove and height of recast layer in relation to the machining parameters using the Response Surface Methodology (RSM) and correspondingly, The formulated mathematical models were put to use for optimization. Since the effect of machining parameters on the depth of groove and height of recast layer was contradictory, The problem was explicated as a multi objective optimization problem. Moreover, An evolutionary Non-dominated sorting genetic algorithm (NSGA-II) was employed to optimize the model established by RSM. Subsequently this algorithm was also adapted to achieve the Pareto optimal set of solutions that provide a detailed illustration for making the optimal solutions. Eventually experiments were conducted to affirm the results obtained from RSM and NSGA-II. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laser%20Micro%20Machining%20%28LMM%29" title="Laser Micro Machining (LMM)">Laser Micro Machining (LMM)</a>, <a href="https://publications.waset.org/abstracts/search?q=depth%20of%20groove" title=" depth of groove"> depth of groove</a>, <a href="https://publications.waset.org/abstracts/search?q=Height%20of%20recast%20layer" title=" Height of recast layer"> Height of recast layer</a>, <a href="https://publications.waset.org/abstracts/search?q=Response%20Surface%20Methodology%20%28RSM%29" title=" Response Surface Methodology (RSM)"> Response Surface Methodology (RSM)</a>, <a href="https://publications.waset.org/abstracts/search?q=non-dominated%20sorting%20genetic%20algorithm" title=" non-dominated sorting genetic algorithm"> non-dominated sorting genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/1651/an-integrated-approach-for-optimal-selection-of-machining-parameters-in-laser-micro-machining-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1651.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Experience of Hydatid Disease of Liver at a Tertiary Care Center 7 Years Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jibran%20Abbasy">Jibran Abbasy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Sultan"> Rizwan Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Humayun"> Ammar Humayun</a>, <a href="https://publications.waset.org/abstracts/search?q=Tabish%20Chawla"> Tabish Chawla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Hydatid disease caused by Echinococcus Granulosus affects liver in 70-90% of cases. Dogs are the definitive host while humans are the accidental host. Modalities used for its treatment are especially important for our population as the disease is endemic in many Asian countries. The aim of the study was to perform an audit of the various modalities used for treatment of hydatid disease of liver and the response to each modality in tertiary care center of Pakistan. Materials and Methods: Retrospective audit of patients diagnosed and treated for Hydatid disease of the liver at Aga Khan University Hospital from 1st January 2007 to 31st December 2014 was completed. All patients aged 16 and above were included. Patients who had extra hepatic disease and missing records were excluded. Outcome measures were morbidity, mortality and recurrence of the disease. Results: During the study period 56 patients were treated for isolated hepatic hydatid disease and were included. Mean age was 39 years with 48% being females and 52% males. Most common presenting complaint was abdominal pain seen in 53% of patients(n=41). Duration of symptoms was less than 6 months in 74% (n=38). Mostly right lobe was involved in 69% (n=38).Most common treatment modality used was surgery in 34 patients followed by PAIR in 14 patients while 8 patients were treated medically. At a median follow up of 34 months recurrence was seen in 2 patients treated with PAIR while no patient treated with surgery had recurrence with the median follow up of 20 months. While no morbidity and mortality were observed in PAIR, but in surgery 5 patients had morbidity while 1 patient had mortality. Conclusion: Our data is comparative to other studies in terms of morbidity, mortality, and recurrence. We had adequate follow up. In our study PAIR and surgery both are effective and have less complications and recurrence rate. Surgery is still the gold standard in terms of recurrence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=echinococcous%20granulosus" title="echinococcous granulosus">echinococcous granulosus</a>, <a href="https://publications.waset.org/abstracts/search?q=puncture%20aspiration%20irrigation%20reaspiration%20%28PAIR%29" title=" puncture aspiration irrigation reaspiration (PAIR)"> puncture aspiration irrigation reaspiration (PAIR)</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=hydatid%20disease" title=" hydatid disease"> hydatid disease</a> </p> <a href="https://publications.waset.org/abstracts/62441/experience-of-hydatid-disease-of-liver-at-a-tertiary-care-center-7-years-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62441.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">266</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Metagenomic Analysis and Pharmacokinetics of Phage Therapy in the Treatment of Bovine Subclinical Mastitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaibhav%20D.%20Bhatt">Vaibhav D.

Around 56 different species including members of Enterobacteriales, Pseudomonadales, Bacillales and Lactobacillales with varying abundance were detected in infected milk. The interesting presence of bacteriophages against Staphylococcus aureus, Escherichia coli, Enterobacter and Yersinia species were observed, especially Enterobacteria and E. coli phages (0∙32%) in Kankrej, Enterobacteria and Staphylococcus phages (1∙05%) in Gir and Staphylococcus phages (2∙32%) in crossbred cattle. NGS findings suggest that phages may be involved in imparting natural resistance of the cattle against pathogens. Further infected milk samples were subjected for bacterial isolation. Fourteen different isolates were identified, and DNA was extracted. Genes (Tet-K, Msr-A, and Mec-A) providing antibiotic resistance to the bacteria were screened by Polymerase Chain Reaction and results were validated with traditional antibiotic assay. Total 3 bacteriophages were isolated from nearby environment of the cattle farm. The efficacy of phages was checked against multi-drug resistant bacteria, identified by PCR. In-vivo study was carried out for phage therapy in mammary glands of female rats “Wister albino”. Mammary glands were infused with MDR isolates for 3 consecutive days. Recovery was observed in infected rats after intramammary infusion of sterile phage suspension. From day 4th onwards, level of C-reactive protein was significant increases up to day 12th . However, significant reduction was observed between days 12th to 18th post treatment. Bacteriophages have significant potential as antibacterial agents and their ability to replicate exponentially within their hosts and their specificity, make them ideal candidates for more sustainable mastitis control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteriophages" title="bacteriophages">bacteriophages</a>, <a href="https://publications.waset.org/abstracts/search?q=c-reactive%20protein" title=" c-reactive protein"> c-reactive protein</a>, <a href="https://publications.waset.org/abstracts/search?q=mastitis" title=" mastitis"> mastitis</a>, <a href="https://publications.waset.org/abstracts/search?q=metagenomic%20analysis" title=" metagenomic analysis"> metagenomic analysis</a> </p> <a href="https://publications.waset.org/abstracts/65533/metagenomic-analysis-and-pharmacokinetics-of-phage-therapy-in-the-treatment-of-bovine-subclinical-mastitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Novel Uses of Discarded Work Rolls of Cold Rolling Mills in Hot Strip Mill of Tata Steel India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uday%20Shanker%20Goel">Uday Shanker Goel</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinay%20Vasant%20Mahashabde"> Vinay Vasant Mahashabde</a>, <a href="https://publications.waset.org/abstracts/search?q=Biswajit%20Ghosh"> Biswajit Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Arvind%20Jha"> Arvind Jha</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Kumar"> Amit Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Patel"> Sanjay Kumar Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=Uma%20Shanker%20Pattanaik"> Uma Shanker Pattanaik</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinit%20Kumar%20Shah"> Vinit Kumar Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Bhanu"> Chaitanya Bhanu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pinch rolls of the Hot Mills must possess resistance to wear, thermal stability, high thermal conductivity and through hardness. Conventionally, pinch rolls have been procured either as new ones or refurbished ones. Discarded Work Rolls from the Cold Mill were taken and machined inhouse at Tata Steel to be used subsequently as the bottom pinch rolls of the Hot Mill. The hardness of the scrapped work rolls from CRM is close to 55HRC and the typical composition is ( C - 0.8% , Mn - 0.40 % , Si - 0.40% , Cr - 3.5% , Mo - 0.5% & V - 0.1% ).The Innovation was the use of a roll which would otherwise have been otherwise discarded as scrap. Also, the innovation helped in using the scrapped roll which had better wear and heat resistance. In a conventional Pinch roil (Hardness 50 HRC and typical chemistry - C - 10% , Mo+Co+V+Nb ~ 5 % ) , Pick-up is a condition whereby foreign material becomes adhered to the surface of the pinch roll during service. The foreign material is usually adhered metal from the actual product being rolled. The main attributes of the weld overlay rolls are wear resistance and crack resistance. However, the weld overlay roll has a strong tendency for strip pick-up particularly in the area of bead overlap. However, the greatest disadvantage is the depth of weld deposit, which is less than half of the usable shell thickness in most mills. Because of this, the stainless rolls require re-welding on a routine basis. By providing a significantly cheaper in house and more robust alternative of the existing bottom pinch rolls , this innovation results in significant lower worries for the roll shop. Pinch rolls now don't have to be sent outside Jamshedpur for refurbishment or for procuring new ones. Scrapped rolls from adjacent Cold Mill are procured and sent for machining to our Machine Shop inside Tata Steel works in Jamshedpur. This is far more convenient than the older methodology. The idea is also being deployed to the other hot mills of Tata Steel. Multiple campaigns have been tried out at both down coilers of Hot Strip with significantly lower wear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20rolling%20flat" title="hot rolling flat">hot rolling flat</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20mill%20work%20roll" title=" cold mill work roll"> cold mill work roll</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20strip%20pinch%20roll" title=" hot strip pinch roll"> hot strip pinch roll</a>, <a href="https://publications.waset.org/abstracts/search?q=strip%20surface" title=" strip surface"> strip surface</a> </p> <a href="https://publications.waset.org/abstracts/166767/novel-uses-of-discarded-work-rolls-of-cold-rolling-mills-in-hot-strip-mill-of-tata-steel-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166767.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> An Autonomous Space Debris-Removal System for Effective Space Missions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shriya%20Chawla">Shriya Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinayak%20Malhotra"> Vinayak Malhotra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Space exploration has noted an exponential rise in the past two decades. The world has started probing the alternatives for efficient and resourceful sustenance along with utilization of advanced technology viz., satellites on earth. Space propulsion forms the core of space exploration. Of all the issues encountered, space debris has increasingly threatened the space exploration and propulsion. The efforts have resulted in the presence of disastrous space debris fragments orbiting the earth at speeds up to several kilometres per hour. Debris are well known as a potential damage to the future missions with immense loss of resources, mankind, and huge amount of money is invested in active research on them. Appreciable work had been done in the past relating to active space debris-removal technologies such as harpoon, net, drag sail. The primary emphasis is laid on confined removal. In recently, remove debris spacecraft was used for servicing and capturing cargo ships. Airbus designed and planned the debris-catching net experiment, aboard the spacecraft. The spacecraft represents largest payload deployed from the space station. However, the magnitude of the issue suggests that active space debris-removal technologies, such as harpoons and nets, still would not be enough. Thus, necessitating the need for better and operative space debris removal system. Techniques based on diverting the path of debris or the spacecraft to avert damage have turned out minimal usage owing to limited predictions. Present work focuses on an active hybrid space debris removal system. The work is motivated by the need to have safer and efficient space missions. The specific objectives of the work are 1) to thoroughly analyse the existing and conventional debris removal techniques, their working, effectiveness and limitations under varying conditions, 2) to understand the role of key controlling parameters in coupled operation of debris capturing and removal. The system represents the utilization of the latest autonomous technology available with an adaptable structural design for operations under varying conditions. The design covers advantages of most of the existing technologies while removing the disadvantages. The system is likely to enhance the probability of effective space debris removal. At present, systematic theoretical study is being carried out to thoroughly observe the effects of pseudo-random debris occurrences and to originate an optimal design with much better features and control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=space%20exploration" title="space exploration">space exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=debris%20removal" title=" debris removal"> debris removal</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20crafts" title=" space crafts"> space crafts</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20accidents" title=" space accidents"> space accidents</a> </p> <a href="https://publications.waset.org/abstracts/100009/an-autonomous-space-debris-removal-system-for-effective-space-missions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100009.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Laminar Periodic Vortex Shedding over a Square Cylinder in Pseudoplastic Fluid Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shubham%20Kumar">Shubham Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Goswami"> Chaitanya Goswami</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudipto%20Sarkar"> Sudipto Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pseudoplastic (n < 1, n being the power index) fluid flow can be found in food, pharmaceutical and process industries and has very complex flow nature. To our knowledge, inadequate research work has been done in this kind of flow even at very low Reynolds numbers. Here, in the present computation, we have considered unsteady laminar flow over a square cylinder in pseudoplastic flow environment. For Newtonian fluid flow, this laminar vortex shedding range lies between Re = 47-180. In this problem, we consider Re = 100 (Re = U∞ a/ ν, U∞ is the free stream velocity of the flow, a is the side of the cylinder and ν is the kinematic viscosity of the fluid). The pseudoplastic fluid range has been chosen from close to the Newtonian fluid (n = 0.8) to very high pseudoplasticity (n = 0.1). The flow domain is constituted using Gambit 2.2.30 and this software is also used to generate mesh and to impose the boundary conditions. For all places, the domain size is considered as 36a × 16a with 280 ×192 grid point in the streamwise and flow normal directions respectively. The domain and the grid points are selected after a thorough grid independent study at n = 1.0. Fine and equal grid spacing is used close to the square cylinder to capture the upper and lower shear layers shed from the cylinder. Away from the cylinder the grid is unequal in size and stretched out in all direction. Velocity inlet (u = U∞), pressure outlet (Neumann condition), symmetry (free-slip boundary condition du/dy = 0, v = 0) at upper and lower domain boundary conditions are used for this simulation. Wall boundary (u = v = 0) is considered on the square cylinder surface. Fully conservative 2-D unsteady Navier-Stokes equations are discretized and then solved by Ansys Fluent 14.5 to understand the flow nature. SIMPLE algorithm written in finite volume method is selected for this purpose which is the default solver in scripted in Fluent. The result obtained for Newtonian fluid flow agrees well with previous work supporting Fluent’s usefulness in academic research. A minute analysis of instantaneous and time averaged flow field is obtained both for Newtonian and pseudoplastic fluid flow. It has been observed that drag coefficient increases continuously with the reduced value of n. Also, the vortex shedding phenomenon changes at n = 0.4 due to flow instability. These are some of the remarkable findings for laminar periodic vortex shedding regime in pseudoplastic flow environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ansys%20Fluent" title="Ansys Fluent">Ansys Fluent</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=periodic%20vortex%20shedding" title=" periodic vortex shedding"> periodic vortex shedding</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudoplastic%20fluid%20flow" title=" pseudoplastic fluid flow"> pseudoplastic fluid flow</a> </p> <a href="https://publications.waset.org/abstracts/97092/laminar-periodic-vortex-shedding-over-a-square-cylinder-in-pseudoplastic-fluid-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Developing an Online Application for Mental Skills Training and Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arjun%20Goutham">Arjun Goutham</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Sridhar"> Chaitanya Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunita%20Maheshwari"> Sunita Maheshwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Robin%20Uthappa"> Robin Uthappa</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanna%20Gopinath"> Prasanna Gopinath</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In alignment with the growth in the sporting industry, a number of people playing and competing in sports are growing exponentially across the globe. However, the number of sports psychology experts are not growing at a similar rate, especially in the Asian and more so, Indian context. Hence, the access to actionable mental training solutions specific to individual athletes is limited. Also, the time constraint an athlete faces due to their intense training schedule makes one-on-one sessions difficult. One of the means to bridge that gap is through technology. Technology makes individualization possible. It allows for easy access to specific-qualitative content/information and provides a medium to place individualized assessments, analysis, solutions directly into an athlete's hands. This enables mental training awareness, education, and real-time actionable solutions possible for athletes in-spite of the limitation of available sports psychology experts in their region. Furthermore, many athletes are hesitant to seek support due to the stigma of appearing weak. Such individuals would prefer a more discreet way. Athletes who have strong mental performance tend to produce better results. The mobile application helps to equip athletes with assessing and developing their mental strategies directed towards improving performance on an ongoing basis. When an athlete understands their strengths and limitations in their mental application, they can focus specifically on applying the strategies that work and improve on zones of limitation. With reports, coaches get to understand the unique inner workings of an athlete and can utilize the data & analysis to coach them with better precision and use coaching styles & communication that suits better. Systematically capturing data and supporting athletes(with individual-specific solutions) or teams with assessment, planning, instructional content, actionable tools & strategies, reviewing mental performance and the achievement of objectives & goals facilitate for a consistent mental skills development at all levels of sporting stages of an athlete's career. The mobile application will help athletes recognize and align with their stable attributes such as their personalities, learning & execution modalities, challenges & requirements of their sport, etc and help develop dynamic attributes like states, beliefs, motivation levels, focus etc. with practice and training. It will provide measurable analysis on a regular basis and help them stay aligned to their objectives & goals. The solutions are based on researched areas of influence on sporting performance individually or in teams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=athletes" title="athletes">athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20training" title=" mental training"> mental training</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20application" title=" mobile application"> mobile application</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=sports" title=" sports"> sports</a> </p> <a href="https://publications.waset.org/abstracts/65981/developing-an-online-application-for-mental-skills-training-and-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65981.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">268</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Two-Dimensional Dynamics Motion Simulations of F1 Rare Wing-Flap</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20H.%20Acharya">Chaitanya H.

For instance, airliners deploy hydraulically operated flaps and ailerons during take-off and landing, while Formula 1 racing cars utilize hydraulic tubes and actuators for various components, including the Drag Reduction System (DRS). The DRS, consisting of a rear wing and adjustable flaps, plays a crucial role in overtaking manoeuvres. The DRS has two positions: the default position with the flaps down, providing high downforce, and the lifted position, which reduces drag, allowing for increased speed and aiding in overtaking. Swift deployment of the DRS during races is essential for overtaking competitors. The fluid flow over the rear wing flap becomes intricate during deployment, involving flow reversal and operational changes, leading to unsteady flow physics that significantly influence aerodynamic characteristics. Understanding the drag and downforce during DRS deployment is crucial for determining race outcomes. While experiments can yield accurate aerodynamic data, they can be expensive and challenging to conduct across varying speeds. Computational Fluid Dynamics (CFD) emerges as a cost-effective solution to predict drag and downforce across a range of speeds, especially with the rapid deployment of the DRS. This study employs the finite volume-based solver Ansys Fluent, incorporating dynamic mesh motions and a turbulent model to capture the complex flow phenomena associated with the moving rear wing flap. A dedicated section for the rare wing-flap is considered in the present simulations, and the aerodynamics of these sections closely resemble S1223 aerofoils. Before delving into the simulations of the rare wing-flap aerofoil, numerical results undergo validation using experimental data from an NLR flap aerofoil case, encompassing different flap angles at two distinct angles of attack was carried out. The increase in flap angle as increase in lift and drag is observed for a given angle of attack. The simulation methodology for the rare-wing-flap aerofoil case involves specific time durations before lifting the flap. During this period, drag and downforce values are determined as 330 N and 1800N, respectively. Following the flap lift, a noteworthy reduction in drag to 55 % and a decrease in downforce to 17 % are observed. This understanding is critical for making instantaneous decisions regarding the deployment of the Drag Reduction System (DRS) at specific speeds, thereby influencing the overall performance of the Formula 1 racing car. Hence, this work emphasizes the utilization of dynamic mesh motion methodology to predict the aerodynamic characteristics during the deployment of the DRS in a Formula 1 racing car. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DRS" title="DRS">DRS</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=drag" title=" drag"> drag</a>, <a href="https://publications.waset.org/abstracts/search?q=downforce" title=" downforce"> downforce</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamics%20mesh%20motion" title=" dynamics mesh motion"> dynamics mesh motion</a> </p> <a href="https://publications.waset.org/abstracts/179293/two-dimensional-dynamics-motion-simulations-of-f1-rare-wing-flap" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179293.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Differential Expression Profile Analysis of DNA Repair Genes in Mycobacterium Leprae by qPCR</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukul%20Sharma">Mukul Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhusmita%20Das"> Madhusmita Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Sundeep%20Chaitanya%20Vedithi"> Sundeep Chaitanya Vedithi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leprosy is a chronic human disease caused by Mycobacterium leprae, that cannot be cultured in vitro. Though treatable with multidrug therapy (MDT), recently, bacteria reported resistance to multiple antibiotics. Targeting DNA replication and repair pathways can serve as the foundation of developing new anti-leprosy drugs. Due to the absence of an axenic culture medium for the propagation of M. leprae, studying cellular processes, especially those belonging to DNA repair pathways, is challenging. Genomic understanding of M. Leprae harbors several protein-coding genes with no previously assigned function known as 'hypothetical proteins'. Here, we report identification and expression of known and hypothetical DNA repair genes from a human skin biopsy and mouse footpads that are involved in base excision repair, direct reversal repair, and SOS response. Initially, a bioinformatics approach was employed based on sequence similarity, identification of known protein domains to screen the hypothetical proteins in the genome of M. leprae, that are potentially related to DNA repair mechanisms. Before testing on clinical samples, pure stocks of bacterial reference DNA of M. leprae (NHDP63 strain) was used to construct standard graphs to validate and identify lower detection limit in the qPCR experiments. Primers were designed to amplify the respective transcripts, and PCR products of the predicted size were obtained. Later, excisional skin biopsies of newly diagnosed untreated, treated, and drug resistance leprosy cases from SIHR & LC hospital, Vellore, India were taken for the extraction of RNA. To determine the presence of the predicted transcripts, cDNA was generated from M. leprae mRNA isolated from clinically confirmed leprosy skin biopsy specimen across all the study groups. Melting curve analysis was performed to determine the integrity of the amplification and to rule out primer‑dimer formation. The Ct values obtained from qPCR were fitted to standard curve to determine transcript copy number. Same procedure was applied for M. leprae extracted after processing a footpad of nude mice of drug sensitive and drug resistant strains. 16S rRNA was used as positive control. Of all the 16 genes involved in BER, DR, and SOS, differential expression pattern of the genes was observed in terms of Ct values when compared to human samples; this was because of the different host and its immune response. However, no drastic variation in gene expression levels was observed in human samples except the nth gene. The higher expression of nth gene could be because of the mutations that may be associated with sequence diversity and drug resistance which suggests an important role in the repair mechanism and remains to be explored. In both human and mouse samples, SOS system – lexA and RecA, and BER genes AlkB and Ogt were expressing efficiently to deal with possible DNA damage. Together, the results of the present study suggest that DNA repair genes are constitutively expressed and may provide a reference for molecular diagnosis, therapeutic target selection, determination of treatment and prognostic judgment in M. leprae pathogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20repair" title="DNA
