Swetha Manian Sridhar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vacuum Assisted Resin Transfer Molding (VARTM), a cost effective method of Liquid Composite Molding (LCM), is a single step process where the resin, at atmospheric pressure, is infused through a preform that is maintained under vacuum. This hydrodynamic pressure gradient is responsible for the flow of resin through the dry fabric preform. The current study has a slight variation to traditional VARTM, wherein, the resin infuses through the fabric placed on a heated mold to reduce its viscosity. The saturated preform is subjected to a cure cycle where the resin hardens as it undergoes curing. During this cycle, an uneven temperature distribution through the thickness of the composite and excess exothermic heat released due to different cure rates result in non-uniform curing. Additionally, there is a difference in thermal expansion coefficient between fiber and resin in a given plane and between adjacent plies. All these effects coupled with orthotropic coefficient of thermal expansion of the composite give rise to process-induced stresses in the laminate. Such stresses lead to part deformation when the laminate tries to relieve them as the part is released off the mold. The current study looks at simulating resin infusion, cure kinetics and the structural response of composite laminate subject to process-induced stresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cure%20kinetics" title="cure kinetics">cure kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=process-induced%20stresses" title=" process-induced stresses"> process-induced stresses</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20expansion%20coefficient" title=" thermal expansion coefficient"> thermal expansion coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20assisted%20resin%20transfer%20molding" title=" vacuum assisted resin transfer molding"> vacuum assisted resin transfer molding</a> </p> <a href="https://publications.waset.org/abstracts/54963/simulation-of-cure-kinetics-and-process-induced-stresses-in-carbon-fibre-composite-laminate-manufactured-by-a-liquid-composite-molding-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54963.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">240</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">36</span> Behaviour of Rc Column under Biaxial Cyclic Loading-State of the Art</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Pavithra">L.

In the present study, a CMB receptor model has been used to identify the sources of PM<sub>2.5</sub>, while the AERMOD dispersion model has been used to account for missing sources of PM<sub>2.5 </sub>in the Emission Inventory. A statistical approach has been developed to quantify the missing sources not considered in the Emission Inventory. The inventory of each grid was improved by adjusting emissions based on road lengths and deficit in measured and modelled concentrations. The results showed that in CMB analyses, fugitive sources - soil and road dust - contribute significantly to ambient PM<sub>2.5</sub> pollution. As a result, AERMOD significantly underestimated the ambient air concentration at most locations. The revised Emission Inventory showed a significant improvement in AERMOD performance which is evident through statistical tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMB" title="CMB">CMB</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=AERMOD" title=" AERMOD"> AERMOD</a>, <a href="https://publications.waset.org/abstracts/search?q=PM%E2%82%82.%E2%82%85" title=" PM₂.₅"> PM₂.₅</a>, <a href="https://publications.waset.org/abstracts/search?q=fugitive" title=" fugitive"> fugitive</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20inventory" title=" emission inventory"> emission inventory</a> </p> <a href="https://publications.waset.org/abstracts/95921/estimation-of-pm25-emissions-and-source-apportionment-using-receptor-and-dispersion-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95921.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">340</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">32</span> Database Management System for Orphanages to Help Track of Orphans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srivatsav%20Sanjay%20Sridhar">Srivatsav Sanjay Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Asvitha%20Raja"> Asvitha Raja</a>, <a href="https://publications.waset.org/abstracts/search?q=Prathit%20Kalra"> Prathit Kalra</a>, <a href="https://publications.waset.org/abstracts/search?q=Soni%20Gupta"> Soni Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Database management is a system that keeps track of details about a person in an organisation. Not a lot of orphanages these days are shifting to a computer and program-based system, but unfortunately, most have only pen and paper-based records, which not only consumes space but it is also not eco-friendly. It comes as a hassle when one has to view a record of a person as they have to search through multiple records, and it will consume time. This program will organise all the data and can pull out any information about anyone whose data is entered. This is also a safe way of storage as physical data gets degraded over time or, worse, destroyed due to natural disasters. In this developing world, it is only smart enough to shift all data to an electronic-based storage system. The program comes with all features, including creating, inserting, searching, and deleting the data, as well as printing them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=database" title="database">database</a>, <a href="https://publications.waset.org/abstracts/search?q=orphans" title=" orphans"> orphans</a>, <a href="https://publications.waset.org/abstracts/search?q=programming" title=" programming"> programming</a>, <a href="https://publications.waset.org/abstracts/search?q=C%E2%81%BA%E2%81%BA" title=" C⁺⁺"> C⁺⁺</a> </p> <a href="https://publications.waset.org/abstracts/159611/database-management-system-for-orphanages-to-help-track-of-orphans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159611.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">156</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">31</span> Load-Settlement Behaviour of Geogrid-Reinforced Sand Bed over Granular Piles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sateesh%20Kumar%20Pisini">Sateesh Kumar Pisini</a>, <a href="https://publications.waset.org/abstracts/search?q=Swetha%20Priya%20Darshini%20Thammadi"> Swetha Priya Darshini Thammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Shukla"> Sanjay Kumar Shukla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Granular piles are a popular ground improvement technique in soft cohesive soils as well as for loose non-cohesive soils. The present experimental study has been carried out on granular piles in loose (Relative density = 30%) and medium dense (Relative density = 60%) sands with geogrid reinforcement within the sand bed over the granular piles. A group of five piles were installed in the sand at different spacing, s = 2d, 3d and 4d, d being the diameter of the pile. The length (L = 0.4 m) and diameter (d = 50 mm) of the piles were kept constant for all the series of experiments. The load-settlement behavior of reinforced sand bed and granular piles system was studied by applying the load on a square footing. The results show that the effect of reinforcement increases the load bearing capacity of the piles. It is also found that an increase in spacing between piles decreases the settlement for both loose and medium dense soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=granular%20pile" title="granular pile">granular pile</a>, <a href="https://publications.waset.org/abstracts/search?q=load-carrying%20capacity" title=" load-carrying capacity"> load-carrying capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=geogrid%20reinforcement" title=" geogrid reinforcement"> geogrid reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=sand" title=" sand"> sand</a> </p> <a href="https://publications.waset.org/abstracts/95179/load-settlement-behaviour-of-geogrid-reinforced-sand-bed-over-granular-piles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95179.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">391</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> Identifying Physiological Markers That Are Sensitive to Cognitive Load in Preschoolers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyashri%20Kamlesh%20Sridhar">Priyashri Kamlesh Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Suranga%20Nanayakkara"> Suranga Nanayakkara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current frameworks in assessment follow lesson delivery and rely heavily on test performance or teacher’s observations. This, however, neglects the underlying cognitive load during the learning process. Identifying the pivotal points when the load occurs helps design effective pedagogies and tools that respond to learners’ cognitive state. There has been limited research on quantifying cognitive load in preschoolers, real-time. In this study, we recorded electrodermal activity and heart rate variability (HRV) from 10 kindergarteners performing executive function tasks and Johnson Woodcock test of cognitive abilities. Preliminary findings suggest that there are indeed sensitive task-dependent markers in skin conductance (number of SCRs and average amplitude of SCRs) and HRV (mean heart rate and low frequency component) captured during the learning process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20childhood" title="early childhood">early childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=methodologies" title=" methodologies"> methodologies</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogies" title=" pedagogies"> pedagogies</a> </p> <a href="https://publications.waset.org/abstracts/74017/identifying-physiological-markers-that-are-sensitive-to-cognitive-load-in-preschoolers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74017.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">320</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> Minimization of Switching Losses in Cascaded Multilevel Inverters Using Efficient Sequential Switching Hybrid-Modulation Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Satish%20Kumar">P.

Hybrid modulation strategies represent the combinations of Fundamental-Frequency Pulse Width Modulation (FFPWM) and Multilevel Sinusoidal-Modulation (MSPWM) strategies, and are designed for performance of the well-known Alternative Phase Opposition Disposition (APOD), Phase Shifted Carrier (PSC). The main characteristics of these modulations are the reduction of switching losses with good harmonic performance, balanced power loss dissipation among the devices with in a cell, and among the series-connected cells. The feasibility of these modulations is verified through spectral analysis, power loss analysis and simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cascaded%20multilevel%20inverters" title="cascaded multilevel inverters">cascaded multilevel inverters</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20modulation" title=" hybrid modulation"> hybrid modulation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20loss%20analysis" title=" power loss analysis"> power loss analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse%20width%20modulation" title=" pulse width modulation"> pulse width modulation</a> </p> <a href="https://publications.waset.org/abstracts/7094/minimization-of-switching-losses-in-cascaded-multilevel-inverters-using-efficient-sequential-switching-hybrid-modulation-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7094.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">537</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">28</span> Experimental Study on Weak Cohesion Less Soil Using Granular Piles with Geogrid Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sateesh%20Kumar%20Pisini">Sateesh Kumar Pisini</a>, <a href="https://publications.waset.org/abstracts/search?q=Swetha%20Priya%20Pisini"> Swetha Priya Pisini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Granular piles are becoming popular as a technique of deep ground improvement not only in soft cohesive soils but also in loose cohesionless deposits. The present experimental study has been carried out on granular piles in sand (loose sand and medium dense sand i.e. relative density at 15% and 30%) with geogrid reinforcement. In this experimental study, a group of five piles installed in sand (at different spacing i.e s = 2d, 3d and 4d) the length and diameter of the pile (L = 0.4 m and d= 50 mm) kept as same for all series of experiments. Geogrid reinforcement is provided on granular piles with a limited number of laboratory tests. It has been conducted in laboratory to study the behavior of a granular pile with reinforced geogrid layers supporting a square footing at different s/d ratios. The influence of geogrid layers providing on granular piles investigated through model tests. In this paper the experimental study carried out results in significant increase in load carrying capacity and decrease in settlement reduction of the weak cohesionless soil. Also, the behavior of load carrying capacity and settlement with changing the s/d ratio has been carried out through a parametric study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=granular%20piles" title="granular piles">granular piles</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesionless%20soil" title=" cohesionless soil"> cohesionless soil</a>, <a href="https://publications.waset.org/abstracts/search?q=geogrid%20reinforcement" title=" geogrid reinforcement"> geogrid reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20carrying%20capacity" title=" load carrying capacity "> load carrying capacity </a> </p> <a href="https://publications.waset.org/abstracts/51022/experimental-study-on-weak-cohesion-less-soil-using-granular-piles-with-geogrid-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51022.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">261</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">27</span> Automatic API Regression Analyzer and Executor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Praveena%20Sridhar">Praveena Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihar%20Devathi"> Nihar Devathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Parikshit%20Chakraborty"> Parikshit Chakraborty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the software product changes versions across releases, there are changes to the API’s and features and the upgrades become necessary.

Here we propose a machine learning-based crop recommendation system to help farmers in choosing the most proper crops according to their geographical regions and soil properties. We can deploy algorithms like Decision Trees, Random Forests and Support Vector Machines on a broad dataset that consists of climatic factors, soil characteristics and historical crop yields to predict the best choice of crops. The approach includes first preprocessing the data after assessing them for missing values, unlike in previous jobs where we used all the available information and then transformed because there was no way such a model could have worked with missing data, and normalizing as throughput that will be done over a network to get best results out of our machine learning division. The model effectiveness is measured through performance metrics like accuracy, precision and recall. The resultant app provides a farmer-friendly dashboard through which farmers can enter their local conditions and receive individualized crop suggestions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20recommendation" title="crop recommendation">crop recommendation</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20agriculture" title=" precision agriculture"> precision agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=crop" title=" crop"> crop</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/193115/crop-recommendation-system-using-machine-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193115.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">15</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">25</span> Material Properties Evolution Affecting Demisability for Space Debris Mitigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chetan%20Mahawar">Chetan Mahawar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarath%20Chandran"> Sarath Chandran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20Panigrahi"> Sridhar Panigrahi</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20P.%20Shaji"> V.

The selection of material and operating conditions is determined with the objective of lightweight structure and ability to demise faster subject to spacecraft survivability during its mission. Since the demisability of spacecraft depends on evolving thermal material properties such as emissivity, specific heat capacity, thermal conductivity, radiation intensity, etc. Therefore, this paper presents the analysis of evolving thermal material properties of spacecraft, which affect the demisability process and thus estimate demise time using the demisability model by incorporating evolving thermal properties for sensible heating followed by the complete or partial break-up of spacecraft. The demisability analysis thus concludes the best suitable spacecraft material is based on the least estimated demise time, which fulfills the criteria of design-for-survivability and as well as of design-for-demisability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demisability" title="demisability">demisability</a>, <a href="https://publications.waset.org/abstracts/search?q=emissivity" title=" emissivity"> emissivity</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight" title=" lightweight"> lightweight</a>, <a href="https://publications.waset.org/abstracts/search?q=re-entry" title=" re-entry"> re-entry</a>, <a href="https://publications.waset.org/abstracts/search?q=survivability" title=" survivability"> survivability</a> </p> <a href="https://publications.waset.org/abstracts/155073/material-properties-evolution-affecting-demisability-for-space-debris-mitigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155073.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">115</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">24</span> Inverse Mode Shape Problem of Hand-Arm Vibration (Humerus Bone) for Bio-Dynamic Response Using Varying Boundary Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20R">Ajay R</a>, <a href="https://publications.waset.org/abstracts/search?q=Rammohan%20B"> Rammohan B</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20K%20S%20S"> Sridhar K S S</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurusharan%20%20N"> Gurusharan N</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of the work is to develop a numerical method to solve the inverse mode shape problem by determining the cross-sectional area of a structure for the desired mode shape via the vibration response study of the humerus bone, which is in the form of a cantilever beam with anisotropic material properties.

Jayathilake</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Iron-based redox flow batteries (IRFB) are promising for grid-scale storage because of their low-cost and environmental safety. Earth-abundant iron can enable affordable grid-storage to meet DOE’s target material cost <$20/kWh and levelized cost for storage $0.05/kWh. In conventional redox flow batteries, energy is stored in external electrolyte tanks and electrolytes are circulated through the cell units to achieve electrochemical energy conversions. However, IRFBs are hybrid battery systems where metallic iron deposition at the negative side of the battery controls the storage capacity. This adds complexity to the design of a porous structure of 3D-electrodes to achieve a desired high storage capacity. In addition, there is a need to control parasitic hydrogen evolution reaction which accompanies the metal deposition process, increases the pH, lowers the energy efficiency, and limits the durability. To achieve sustainable operation of IRFBs, electrolyte pH, which affects the solubility of reactants and the rate of parasitic reactions, needs to be dynamically readjusted. In the present study we explore the impact of complexing agents on maintaining solubility of the reactants and find the optimal electrolyte conditions and battery operating regime, which are specific for IRFBs with additives, and demonstrate the robust operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20battery" title="flow battery">flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=iron-based%20redox%20flow%20battery" title=" iron-based redox flow battery"> iron-based redox flow battery</a>, <a href="https://publications.waset.org/abstracts/search?q=IRFB" title=" IRFB"> IRFB</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title=" electrochemistry"> electrochemistry</a> </p> <a href="https://publications.waset.org/abstracts/168063/engineered-reactor-components-for-durable-iron-flow-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168063.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">22</span> A Witty Relief Ailment Based on the Integration of IoT and Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sai%20Shruthi%20Sridhar">Sai Shruthi Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Madhumidha"> A.

Similar to Technology world, one industry stands out in everyday life–healthcare. Attention to “quality of health care” is an increasingly important issue in a global economy and for every individual. As per WHO (World Health Organization) it is estimated to be less than 50% adhere to the medication provided and only about 20% get their medicine on time. Medication adherence is one of the top problems in healthcare which is fixable by use of technology. In recent past, there were minor provisions for elderly and specially-skilled to get motivated and to adhere medicines prescribed. This paper proposes a novel solution that uses IOT based RFID Medication Reminder Solution to provide personal health care services. This employs real time tracking which offer quick counter measures. The proposed solution builds on the recent digital advances in sensor technologies, smart phones and cloud services. This novel solution is easily adoptable and can benefit millions of people with a direct impact on the nation’s health care expenditure with innovative scenarios and pervasive connectivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20services" title="cloud services">cloud services</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=RFID" title=" RFID"> RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=sensors" title=" sensors"> sensors</a> </p> <a href="https://publications.waset.org/abstracts/63234/a-witty-relief-ailment-based-on-the-integration-of-iot-and-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63234.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">347</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> A Study on Exploring and Prioritizing Critical Risks in Construction Project Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Swetha">A.

Through extensive literature review and expert interviews, project assessment risk factors were identified across Budget and Cost Management Risk, Schedule and Time Management Risk, Scope and Planning Risk, Safety and Regulatory Compliance Risk, Resource Management Risk, Communication and Stakeholder Management Risk, and Environmental and Sustainability Risk domains. A questionnaire was distributed to stakeholders involved in construction activities in Hyderabad, India, with 180 completed responses analyzed using the Weighted Average Index method to prioritize risk factors. Subsequently, PCA was used to understand relationships between these factors and uncover underlying patterns. Results highlighted dependencies on critical resources, inadequate risk assessment, cash flow constraints, and safety concerns as top priorities, while factors like currency exchange rate fluctuations and delayed information dissemination ranked lower but remained significant. These insights offer valuable guidance for stakeholders to mitigate risks effectively and enhance project outcomes.

In this study, ID3 chooses the splitting attribute with the highest gain in information, where gain is defined as the difference between before the split versus after the split. It is applied for age, location, taluk, stage, year, period, martial status, treatment, heredity, sex, and habitat against Very Serious (VS), Very Serious Moderate (VSM), Serious (S) and Not Serious (NS) to calculate the gain of information. The ranked histogram gives the gain of each field for the breast cancer data. The doctors use TNM staging which will decide the risk level of the breast cancer and play an important decision making field in fuzzy logic for perception based measurement. Spatial risk area (taluk) of the breast cancer is calculated. Result clearly states that Coimbatore (North and South) was found to be risk region to the breast cancer than other areas at 20% criteria. Weighted value of taluk was compared with criterion value and integrated with Map Object to visualize the results. ID3 algorithm shows the high breast cancer risk regions in the study area.

Sustainable construction is a way for the building and infrastructure industry to move towards achieving sustainable development, taking into account environmental, socioeconomic and cultural issues. Geotechnical engineering, being very resource intensive, warrants an environmental sustainability study, but a quantitative framework for assessing the sustainability of geotechnical practices, particularly at the planning and design stages, does not exist. In geotechnical projects, major economic issues to be addressed are in the design and construction of stable slopes and retaining structures within space constraints. In this paper, quantitative indicators for assessing the environmental sustainability of retaining wall with geosynthetics are compared with conventional concrete retaining wall through life cycle assessment (LCA). Geosynthetics can make a real difference in sustainable construction techniques and contribute to development in developing countries in particular. Their imaginative application can result in considerable cost savings over the use of conventional designs and materials. The acceptance of geosynthetics in reinforced retaining wall construction has been triggered by a number of factors, including aesthetics, reliability, simple construction techniques, good seismic performance, and the ability to tolerate large deformations without structural distress. Reinforced retaining wall with geosynthetics is the best cost-effective and eco-friendly solution as compared with traditional concrete retaining wall construction. This paper presents an analysis of the theme of sustainability applied to the design and construction of traditional concrete retaining wall and presenting a cost-effective and environmental solution using geosynthetics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainability" title="sustainability">sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=retaining%20wall" title=" retaining wall"> retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=geosynthetics" title=" geosynthetics"> geosynthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a> </p> <a href="https://publications.waset.org/abstracts/81842/sustainability-in-retaining-wall-construction-with-geosynthetics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81842.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">2060</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> Evaluation of Hand Arm Vibrations of Low Profile Dump Truck Operators in an Underground Metal Mine According to Job Component Analysis of a Work Cycle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20S">Sridhar S</a>, <a href="https://publications.waset.org/abstracts/search?q=Govinda%20Raj%20Mandela"> Govinda Raj Mandela</a>, <a href="https://publications.waset.org/abstracts/search?q=Aruna%20Mangalpady"> Aruna Mangalpady</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present day scenario, Indian underground mines are moving towards full scale mechanisation for improvement of production and productivity levels. These mines are employing a wide variety of earth moving machines for the transportation of ore and overburden (waste). Low Profile Dump Trucks (LPDTs) have proven more advantageous towards improvement of production levels in underground mines through quick transportation. During the operation of LPDT, different kinds of vibrations are generated which can affect the health condition of the operator. Keeping this in view, the present research work focuses on measurement and evaluation of Hand Arm Vibrations (HAVs) from the steering system of LPDTs. The study also aims to evaluate the HAVs of different job components of a work cycle in operating LPDTs. The HAVs were measured and evaluated according to ISO 5349-2: 2001 standards, and the daily vibration exposures A(8) were calculated. The evaluated A(8) results show that LPDTs of 60 and 50 tons capacity have vibration levels more than that of the Exposure Action Value (EAV) of 2.5 m/s2 in every job component of the work cycle. Further, the results show that the vibration levels were more during empty haulage especially during descending journey when compared to other job components in all LPDTs considered for the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20profile%20dump%20trucks" title="low profile dump trucks">low profile dump trucks</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20arm%20vibrations" title=" hand arm vibrations"> hand arm vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20action%20value" title=" exposure action value"> exposure action value</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20mines" title=" underground mines"> underground mines</a> </p> <a href="https://publications.waset.org/abstracts/120502/evaluation-of-hand-arm-vibrations-of-low-profile-dump-truck-operators-in-an-underground-metal-mine-according-to-job-component-analysis-of-a-work-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120502.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">131</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> Shrinkage Evaluation in a Stepped Wax Pattern – a Simulation Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20S%20Chauhan">Alok S Chauhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20S."> Sridhar S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradyumna%20R."> Pradyumna R.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the process of precision investment casting of turbine hollow blade/vane components, a part of the dimensional deviations observed in the castings can be attributed to the wax pattern. In the process of injection moulding of wax to produce patterns, heated wax shrinks in size during cooling in the die, leading to a reduction in the dimensions of the pattern. Also, flow and thermal induced residual stresses result in shrinkage & warpage of the component after removal from the die, further adding to the deviations. Injection moulding parameters such as wax temperature, flow rate, packing pressure, etc. affect the flow and thermal behavior of the component and hence are directly responsible for the dimensional deviations. There is a need to precisely determine and control these deviations in order to achieve stringent dimensional accuracies imposed on these castings by aerospace standards. Simulation based approaches provide a platform to predict these dimensional deviations without resorting to elaborate experimentation. In the present paper, Moldex3D simulation package has been utilized to analyze the effect of variations in injection temperature, packing pressure and cooling time on the shrinkage behavior of a stepped pattern. Two types of waxes with different rheological properties have been included in the study to gauge the effect of change in wax on the dimensional deviations. A full factorial design of experiments has been configured with these parameters and results of analysis of variance have been presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wax%20patterns" title="wax patterns">wax patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20casting" title=" investment casting"> investment casting</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20die%2Fmould" title=" pattern die/mould"> pattern die/mould</a>, <a href="https://publications.waset.org/abstracts/search?q=wax%20injection" title=" wax injection"> wax injection</a>, <a href="https://publications.waset.org/abstracts/search?q=Moldex3D%20simulation" title=" Moldex3D simulation"> Moldex3D simulation</a> </p> <a href="https://publications.waset.org/abstracts/19217/shrinkage-evaluation-in-a-stepped-wax-pattern-a-simulation-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19217.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">373</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> Quantification of Dowel-Concrete Interaction in Jointed Plain Concrete Pavements Using 3D Numerical Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lakshmana%20Ravi%20Raj%20Gali">Lakshmana Ravi Raj Gali</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20Sridhar%20Reddy"> K.

Dowel bars are generally used to ensure sufficient degree of load transfer, in addition to the load transferred by aggregate interlock mechanism at the joints. Joint efficiency is the measure of joint quality, a major concern and therefore the dowel bar system should be designed and constructed well. The interaction between dowel bars and concrete that includes various parameters of dowel bar and concrete will explain the degree of joint efficiency. The present study focuses on the methodology of selecting contact stiffness, which quantifies dowel-concrete interaction. In addition, a parametric study which focuses on the effect of dowel diameter, dowel shape, the spacing between dowel bars, joint opening, the thickness of the slab, the elastic modulus of concrete, and concrete cover on contact stiffness was also performed. The results indicated that the thickness of the slab is most critical among various parameters to explain the joint efficiency. Further displacement equivalency method was proposed to find out the contact stiffness. The proposed methodology was validated with the available field surface deflection data collected by falling weight deflectometer (FWD). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20stiffness" title="contact stiffness">contact stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement%20equivalency%20method" title=" displacement equivalency method"> displacement equivalency method</a>, <a href="https://publications.waset.org/abstracts/search?q=Dowel-concrete%20interaction" title=" Dowel-concrete interaction"> Dowel-concrete interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20behavior" title=" joint behavior"> joint behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20numerical%20simulation" title=" 3D numerical simulation"> 3D numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/105004/quantification-of-dowel-concrete-interaction-in-jointed-plain-concrete-pavements-using-3d-numerical-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105004.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">151</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> Ectopic Pregnancy: A Case of Consecutive Occurrences of Different Types</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wania%20Mohammad%20Akram">Wania Mohammad Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Swetha%20Kannan"> Swetha Kannan</a>, <a href="https://publications.waset.org/abstracts/search?q=Urooj%20Shahid"> Urooj Shahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Sajjad"> Aisha Sajjad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ovarian ectopic pregnancy, a rare manifestation of ectopic gestation, involves the implantation of a fertilized egg on the ovarian surface. This condition poses diagnostic challenges and is associated with significant maternal morbidity if not promptly managed. This report presents the case of a 33-year-old nulliparous woman with a history of polycystic ovary syndrome (PCOS) undergoing ovulation induction therapy. Following her first conception in October 2021, she presented with symptoms of per vaginal spotting and low back pain, prompting a diagnosis of left adnexal ectopic pregnancy confirmed by transvaginal ultrasound and serum beta-human chorionic gonadotropin (B-HCG) levels. Medical management with methotrexate was initiated successfully. In August 2022, the patient conceived again, with subsequent ultrasound revealing a large pelvic collection suggestive of a complex ectopic pregnancy involving both ovaries. Despite initial stability, she developed abdominal pain necessitating emergency laparoscopy, which revealed an ovarian ectopic pregnancy with hemoperitoneum. Laparotomy was performed due to the complexity of the presentation, and histopathology confirmed viable chorionic villi within ovarian tissue. This case underscores the clinical management challenges posed by ovarian ectopic pregnancies, particularly in patients with previous ectopic pregnancies. The discussion reviews current literature on diagnostic modalities, treatment strategies, and outcomes associated with ovarian ectopic pregnancies, emphasizing the role of surgical intervention in cases refractory to conservative management. Tailored approaches considering individual patient factors are crucial to optimize outcomes and preserve fertility in such complex scenarios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obgyn" title="obgyn">obgyn</a>, <a href="https://publications.waset.org/abstracts/search?q=ovarian%20ectopic%20pregnancy" title=" ovarian ectopic pregnancy"> ovarian ectopic pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=laproscopy" title=" laproscopy"> laproscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=pcos" title=" pcos"> pcos</a> </p> <a href="https://publications.waset.org/abstracts/188354/ectopic-pregnancy-a-case-of-consecutive-occurrences-of-different-types" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188354.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">36</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> Development of Pre-Mitigation Measures and Its Impact on Life-Cycle Cost of Facilities: Indian Scenario</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahima%20Shrivastava">Mahima Shrivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumya%20Kar"> Soumya Kar</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Swetha%20Malika"> B.

Generalized pre-mitigation strategies introduced and adopted for prevention of disaster all over the world are capable of augmenting the resiliency and optimizing the life-cycle cost of facilities. In countries like India where varied topographical feature exists requires location specific mitigation measures and strategies to be followed for better enhancement by event-driven and code-driven approaches. Present state of vindication measures followed and adopted, lags dominance in accomplishing the required development. In addition, serious concern and debate over climate change plays a vital role in enhancing the need and requirement for the development of time bound adaptive mitigation measures. For the development of long-term sustainable policies incorporation of future climatic variation is inevitable. This will further assist in assessing the impact brought about by the climate change on life-cycle cost of facilities. This paper develops more definite region specific and time bound pre-mitigation measures, by reviewing the present state of mitigation measures in India and all over the world for improving life-cycle cost of facilities. For the development of region specific adoptive measures, Indian regions were divided based on multiple-calamity prone regions and geo-referencing tools were used to incorporate the effect of climate changes on life-cycle cost assessment. This study puts forward significant effort in establishing sustainable policies and helps decision makers in planning for pre-mitigation measures for different regions. It will further contribute towards evaluating the life cycle cost of facilities by adopting the developed measures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=geo-referencing%20tools" title=" geo-referencing tools"> geo-referencing tools</a>, <a href="https://publications.waset.org/abstracts/search?q=life-cycle%20cost" title=" life-cycle cost"> life-cycle cost</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple-calamity%20prone%20regions" title=" multiple-calamity prone regions"> multiple-calamity prone regions</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-mitigation%20strategies" title=" pre-mitigation strategies"> pre-mitigation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20policies" title=" sustainable policies"> sustainable policies</a> </p> <a href="https://publications.waset.org/abstracts/43031/development-of-pre-mitigation-measures-and-its-impact-on-life-cycle-cost-of-facilities-indian-scenario" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43031.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">379</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> The Application of Robotic Surgical Approaches in the Management of Midgut Neuroendocrine Tumours: A Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jatin%20Sridhar%20Naidu">Jatin Sridhar Naidu</a>, <a href="https://publications.waset.org/abstracts/search?q=Aryan%20Arora"> Aryan Arora</a>, <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Shafiq"> Zainab Shafiq</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Mirnezami"> Reza Mirnezami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Robotic-assisted surgery (RAS) promises good outcomes in midgut adenocarcinoma surgery. However, its effectiveness in midgut neuroendocrine tumours (MNETs) is unknown. This study aimed to assess the current use, user interface, and any emerging developments of RAS in MNET treatment using the literature available. Methods: This review was carried out using PRISMA guidelines. MEDLINE, EMBASE, and Web of Science were searched on 22nd October 2022. All studies reporting primary data on robotic surgery in midgut neuroendocrine tumours or carcinoid tumours were included. The midgut was defined to be from the duodenojejunal flexure to the splenic flexure. Methodological quality was assessed using the Joanna Briggs critical appraisal tool. Results: According to our systematic review protocol, nineteen studies were selected. A total of twenty-six patients were identified. RAS was used for right colectomies, right hemicolectomies, ileal resections, caecal resections, intracorporeal anastomoses, and complete mesocolic excisions. It offered an optimal user-interface with enhanced visuals, fine dexterity, and ergonomic work position. Innovative developments in tumour-healthy tissue boundary and vasculature visualisation were reported. Conclusion: RAS for MNETs is safe and feasible, although the evidence base is limited. We recommend large prospective-randomised controlled trials comparing it with laparoscopy and open surgery. Developments in intraoperative contrast dyes and tumour-specific probes are very promising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic%20surgery" title="robotic surgery">robotic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=colorectal%20surgery" title=" colorectal surgery"> colorectal surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroendocrine%20neoplasms" title=" neuroendocrine neoplasms"> neuroendocrine neoplasms</a>, <a href="https://publications.waset.org/abstracts/search?q=midgut%20neoplasms" title=" midgut neoplasms"> midgut neoplasms</a> </p> <a href="https://publications.waset.org/abstracts/160940/the-application-of-robotic-surgical-approaches-in-the-management-of-midgut-neuroendocrine-tumours-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160940.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">12</span> Design and Simulation of an Inter-Satellite Optical Wireless Communication System Using Diversity Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20Rapuru">Sridhar Rapuru</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20Mallikarjunreddy"> D.

To achieve this goal, it is very important to have a good network without any interruptions between the satellites along with various earth stations. For that purpose, a high speed inter-satellite optical wireless communication system (IsOWC) is designed with space and polarization diversity techniques. IsOWC offers a high bandwidth, small size, less power requirement and affordable when compared with the present microwave satellite systems. To improve the efficiency and to reduce the propagation delay, inter-satellite link is established between the satellites. High accurate tracking systems are required to establish the reliable connection between the satellites as they have their own orbits. The only disadvantage of this IsOWC system is laser beam width is narrower than the RF because of this highly accurate tracking system to meet this requirement. The satellite uses the 'ephemerides data' for rough pointing and tracking system for fine pointing to the other satellite. In this proposed IsOWC system, laser light is used as a wireless connectedness between the source and destination and free space acts as the channel to carry the message. The proposed system will be designed, simulated and analyzed for 6000km with an improvement of data rate over previously existing systems. The performance parameters of the system are Q-factor, eye opening, bit error rate, etc., The proposed system for Inter-satellite Optical Wireless Communication System Design Using Diversity Techniques finds huge scope of applications in future generation communication purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter-satellite%20optical%20wireless%20system" title="inter-satellite optical wireless system">inter-satellite optical wireless system</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20and%20polarization%20diversity%20techniques" title=" space and polarization diversity techniques"> space and polarization diversity techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20of%20sight" title=" line of sight"> line of sight</a>, <a href="https://publications.waset.org/abstracts/search?q=bit%20error%20rate" title=" bit error rate"> bit error rate</a>, <a href="https://publications.waset.org/abstracts/search?q=Q-factor" title=" Q-factor"> Q-factor</a> </p> <a href="https://publications.waset.org/abstracts/74440/design-and-simulation-of-an-inter-satellite-optical-wireless-communication-system-using-diversity-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74440.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">269</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> In vitro Assessment of Bioactive Properties and Dose-Dependent Antioxidant Activities of Commercial Grape Cultivars in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kandi%20Sridhar">Kandi Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Albert%20Linton"> Charles Albert Linton </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Grapes are excellent sources of bioactive compounds, which have been suggested to be responsible for lowering the risk of chronic diseases. Fresh and freeze-dried extracts of Kyoho and Jubilee, commercial grape varieties available in Taiwan and attractive for their quality berries, were investigated for their total phenolics and total ﬂavonoids contents and related dose-dependent antioxidants properties using various in vitro assays. The efficiency of the extraction yield ranged from 7.10 % to 25.53 % (w/w), depending on solvent used. Fresh samples of Kyoho and Jubilee exhibited total polyphenolic contents (351.56 ± 23.08 and 328.67 ± 16.54 µg GAE/mL, respectively), whereas Kyoho freeze-dried methanol: water extracts contains the good levels of total flavonoids (4767.82 ± 22.20 µg QE/mL). Kyoho and Jubilee freeze-dried extracts exhibited the highest total flavonoid contents. There was a weak correlation between total phenolic and flavonoid assays (r= -0.05, R2 = 0.02, p > 0.05). Kyoho fresh and freeze-dried samples showed the DPPH (11.51 – 77.82 %), superoxide scavenging activity (33.61 – 81.95 %), and total antioxidant inhibition (92.01 – 99.28 %), respectively. Total flavonoids were statistically correlated with EC50 DPPH scavenging radicals (r =0.91, p < 0.01), EC50 nitric oxide (r = 0.25, p > 0.05), and EC50 lipid peroxidation radicals (r = 0.38, p > 0.05). These results suggested that the two commercial grape cultivars in Taiwan could be used as a good source of natural antioxidants. Thus, consumption of grapes as a source antioxidant might lower the risk of chronic diseases. Moreover, future studies will investigate and develop phenolic acid profile for the cultivars in Taiwan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title="antioxidants">antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=EC50%20radical%20scavenging%20activity" title=" EC50 radical scavenging activity"> EC50 radical scavenging activity</a>, <a href="https://publications.waset.org/abstracts/search?q=grape%20cultivars" title=" grape cultivars"> grape cultivars</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenolics" title=" total phenolics "> total phenolics </a> </p> <a href="https://publications.waset.org/abstracts/78841/in-vitro-assessment-of-bioactive-properties-and-dose-dependent-antioxidant-activities-of-commercial-grape-cultivars-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78841.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">178</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> Epstein, Barr Virus Alters ATM-Dependent DNA Damage Responses in Germinal Centre B-Cells during Early Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20N.%20Maina">Esther N.

The demonstration that a proportion of Hodgkin lymphomas and all Burkitt’s lymphomas harbour EBV suggests that the virus contributes to the development of these malignancies. However, the mechanisms of lymphomagenesis remain largely unknown. To determine whether EBV causes DNA damage and alters DNA damage response in cells of EBV-driven lymphoma origin, Germinal Centre (GC) B cells were infected with EBV and DNA damage responses to gamma ionising radiation (IR) assessed at early time points (12hr – 72hr) after infection and prior to establishment of lymphoblastoid (LCL) cell lines. In the presence of EBV, we observed induction of spontaneous DNA DSBs and downregulation of ATM-dependent phosphorylation in response to IR. This downregulation coincided with reduced ability of infected cells to repair IR-induced DNA double-strand breaks, as measured by the kinetics of gamma H2AX, a marker of double-strand breaks, and by the tail moment of the comet assay. Furthermore, we found that alteration of DNA damage responses coincided with the expression of LMP-1 protein. The presence of the EBV virus did not affect the localization of the ATM-dependent DNA repair proteins to sites of damage but instead lead to an increased expression of PP5, a phosphatase that regulates ATM function. The impact of the virus on DNA repair was most prominent 24h after infection, suggesting that this time point is crucial for the viral establishment in B cells. Our results suggest that during an early infection EBV virus dampens crucial cellular responses to DNA double-strand breaks which facilitate successful viral infection, but at the same time might provide the mechanism for tumor development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EBV" title="EBV">EBV</a>, <a href="https://publications.waset.org/abstracts/search?q=ATM" title=" ATM"> ATM</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage" title=" DNA damage"> DNA damage</a>, <a href="https://publications.waset.org/abstracts/search?q=germinal%20center%20cells" title=" germinal center cells"> germinal center cells</a> </p> <a href="https://publications.waset.org/abstracts/24945/epstein-barr-virus-alters-atm-dependent-dna-damage-responses-in-germinal-centre-b-cells-during-early-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24945.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">349</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> 3D Numerical Simulation of Undoweled and Uncracked Joints in Short Paneled Concrete Pavements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Sridhar%20Reddy">K.

Cast-in-situ short concrete panels (short slabs) laid on a strong foundation consisting of a dry lean concrete base (DLC), and cement treated subbase (CTSB) will reduce the thickness of the concrete slab to the order of 180 mm to 220 mm, whereas JPCP was with 280 mm for the same traffic. During the construction of SPCP test sections on two Indian National Highways (NH), it was observed that the joints remain uncracked after a year of traffic. The undoweled and uncracked joints load transfer variability and joint behavior are of interest with anticipation on its long-term performance of the SPCP. To investigate the effects of undoweled and uncracked joints on short slabs, the present study was conducted. A multilayer linear elastic analysis using 3D finite element package for different panel sizes with different thicknesses resting on different types of solid elastic foundation with and without temperature gradient was developed. Surface deflections were obtained from 3D FE model and validated with measured field deflections from falling weight deflectometer (FWD) test. Stress analysis indicates that flexural stresses in short slabs are decreased with a decrease in panel size and increase in thickness. Detailed evaluation of stress analysis with the effects of curling behavior, the stiffness of the base layer and a variable degree of load transfer, is underway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20behavior" title="joint behavior">joint behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20slabs" title=" short slabs"> short slabs</a>, <a href="https://publications.waset.org/abstracts/search?q=uncracked%20joints" title=" uncracked joints"> uncracked joints</a>, <a href="https://publications.waset.org/abstracts/search?q=undoweled%20joints" title=" undoweled joints"> undoweled joints</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20numerical%20simulation" title=" 3D numerical simulation"> 3D numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/105020/3d-numerical-simulation-of-undoweled-and-uncracked-joints-in-short-paneled-concrete-pavements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105020.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">181</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> Verification of a Simple Model for Rolling Isolation System Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aarthi%20Sridhar">Aarthi Sridhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Henri%20Gavin"> Henri Gavin</a>, <a href="https://publications.waset.org/abstracts/search?q=Karah%20Kelly"> Karah Kelly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rolling Isolation Systems (RISs) are simple and effective means to mitigate earthquake hazards to equipment in critical and precious facilities, such as hospitals, network collocation facilities, supercomputer centers, and museums. The RIS works by isolating components acceleration the inertial forces felt by the subsystem. The RIS consists of two platforms with counter-facing concave surfaces (dishes) in each corner. Steel balls lie inside the dishes and allow the relative motion between the top and bottom platform. Formerly, a mathematical model for the dynamics of RISs was developed using Lagrange’s equations (LE) and experimentally validated. A new mathematical model was developed using Gauss’s Principle of Least Constraint (GPLC) and verified by comparing impulse response trajectories of the GPLC model and the LE model in terms of the peak displacements and accelerations of the top platform. Mathematical models for the RIS are tedious to derive because of the non-holonomic rolling constraints imposed on the system. However, using Gauss’s Principle of Least constraint to find the equations of motion removes some of the obscurity and yields a system that can be easily extended. Though the GPLC model requires more state variables, the equations of motion are far simpler. The non-holonomic constraint is enforced in terms of accelerations and therefore requires additional constraint stabilization methods in order to avoid the possibility that numerical integration methods can cause the system to go unstable. The GPLC model allows the incorporation of more physical aspects related to the RIS, such as contribution of the vertical velocity of the platform to the kinetic energy and the mass of the balls. This mathematical model for the RIS is a tool to predict the motion of the isolation platform. The ability to statistically quantify the expected responses of the RIS is critical in the implementation of earthquake hazard mitigation. <p class="card-text"><strong>Keywords:</strong> <a
