It is capable of amplifying radio frequency (RF) power with very good efficiency. Its compactness, reliability, high efficiency, high linearity and low operating cost make this device suitable for various applications. The device consists of an integrated structure of electron gun and RF cavity, collector and focusing structure. The working principle of IOT is a combination of triode and klystron. The cathode lies in the electron gun produces a stream of electrons. A control grid is placed in close proximity to the cathode. Basically, the input part of IOT is the integrated structure of gridded electron gun which acts as an input cavity thereby providing the interaction gap where the input RF signal is applied to make it interact with the produced electron beam for supporting the amplification phenomena. The paper presents the design, fabrication and testing of a radial re-entrant cavity for implementing in the input structure of IOT at 350 MHz operating frequency. The model’s suitability has been discussed and a generalized mathematical relation has been introduced for getting the proper transverse magnetic (TM) resonating mode in the radial narrow gap RF cavities. The structural modeling has been carried out in CST and SUPERFISH codes. The cavity is fabricated with the Aluminum material and the RF characterization is done using vector network analyzer (VNA) and the results are presented for the resonant frequency peaks obtained in VNA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inductive%20output%20tubes" title="inductive output tubes">inductive output tubes</a>, <a href="https://publications.waset.org/abstracts/search?q=IOT" title=" IOT"> IOT</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20cavity" title=" radial cavity"> radial cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=coaxial%20cavity" title=" coaxial cavity"> coaxial cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20accelerators" title=" particle accelerators"> particle accelerators</a> </p> <a href="https://publications.waset.org/abstracts/98117/design-and-radio-frequency-characterization-of-radial-reentrant-narrow-gap-cavity-for-the-inductive-output-tube" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98117.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">124</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">1643</span> Insights and Observation for Optimum Work Roll Cooling in Flat Hot Mills: A Case Study on Shape Defect Elimination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uday%20S.%20Goel">Uday S.

This was resulting in a defect called as ‘Ridge’, which was appearing in subsequent cold rolling operations at various cold mills (CRM) and external customers. A collaborative project was undertaken to resolve this issue. One of the reasons identified was the strange drop in thermal crown after rolling of 20-25 coils in the finishing mill (FM ) schedule. On the shop floor, it was observed that work roll temperatures in the FM after rolling were very high and non uniform across the work roll barrel. Jammed work roll cooling nozzles, insufficient roll bite lubrication and inadequate roll cooling water quality were found to be the main reasons. Regular checking was initiated to check roll cooling nozzles health, and quick replacement done if found jammed was implemented. Improvements on roll lubrication, especially flow rates, was done. Usage of anti-peeling headers and inter stand descaling was enhanced. A subsequent project was also taken up for improving the quality of roll cooling water. Encouraging results were obtained from the project with a reduction in rejection due to ridge at CRM’s by almost 95% of the pre project start levels. Poor profile occurrence of HR coils at HSM was also reduced from a high of 32% in May’19 to <1% since Apr’20. <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=shape" title=" shape"> shape</a>, <a href="https://publications.waset.org/abstracts/search?q=ridge" title=" ridge"> ridge</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20roll" title=" work roll"> work roll</a>, <a href="https://publications.waset.org/abstracts/search?q=roll%20cooling%20nozzle" title=" roll cooling nozzle"> roll cooling nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=lubrication" title=" lubrication"> lubrication</a> </p> <a href="https://publications.waset.org/abstracts/166771/insights-and-observation-for-optimum-work-roll-cooling-in-flat-hot-mills-a-case-study-on-shape-defect-elimination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166771.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">99</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">1642</span> Experimental Investigations to Measure Surface Fatigue Wear in Journal Bearing by Using Vibration Signal Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amarnath%20M.">Amarnath M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramachandra%20C.%20G."> Ramachandra C.

Extract of PB and ZR at the tested doses restored the levels of liver homogenate enzymes, glutathione peroxidase, glutathione-S-transferase, superoxide dismutase and catalase enzymes, significantly. The activities of MTT assay significantly recovered the damage and supported the biochemical observations. This study suggests that Zingiber roseum has a higher protective effect on liver, compared to Polygonum bistorta, against carbon tetrachloride-induced hepatotoxicity and possesses antioxidant activities.

As a result, it is crucial to analyze the IoT platform as a whole from the standpoint of core security concepts. The Internet of Things relies heavily on wireless networks, which are well-known for being susceptible to a wide variety of attacks. This article provides an analysis of many techniques that may be used to identify vulnerabilities in the software and hardware associated with the Internet of Things (IoT). In the current investigation, an experimental setup is built with the assistance of server computers, client PCs, Internet of Things development boards, sensors, and cloud subscriptions. Through the use of network host scanning methods and vulnerability scanning tools, raw data relating to IoT-based applications and devices may be collected. Shodan is a tool that is used for scanning, and it is also used for effective vulnerability discovery in IoT devices as well as penetration testing.

The studies picked for this paper range from the nascent stages of the emergence of the concept of corporate sustainability in business to present-day targeted studies on SMEs. This study has attempted to highlight the recurring, emerging, and neglected themes in the literature and concludes with some key findings: 1) the research on sustainability and SMEs remains focused on generic rather than targeted studies; 2) sustainability frameworks specifically designed for SMEs remain under-researched as opposed to large firms, 3) there is a requirement to look more at the SMEs in the service sector. This paper also highlights other dominant themes in literature and, finally, offers suggestions for areas of future research. <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=small%20and%20medium-sized%20enterprises" title=" small and medium-sized enterprises"> small and medium-sized enterprises</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/162239/thematic-review-of-literature-on-sustainability-and-small-and-medium-sized-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162239.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">83</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">1638</span> Recovery of Fried Soybean Oil Using Bentonite as an Adsorbent: Optimization, Isotherm and Kinetics Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prakash%20Kumar%20Nayak">Prakash Kumar Nayak</a>, <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Kumar"> Avinash Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Uma%20Dash"> Uma Dash</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalpana%20Rayaguru"> Kalpana Rayaguru</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soybean oil is one of the most widely consumed cooking oils, worldwide. Deep-fat frying of foods at higher temperatures adds unique flavour, golden brown colour and crispy texture to foods. But it brings in various changes like hydrolysis, oxidation, hydrogenation and thermal alteration to oil. The presence of Peroxide value (PV) is one of the most important factors affecting the quality of the deep-fat fried oil. Using bentonite as an adsorbent, the PV can be reduced, thereby improving the quality of the soybean oil. In this study, operating parameters like heating time of oil (10, 15, 20, 25 & 30 h), contact time ( 5, 10, 15, 20, 25 h) and concentration of adsorbent (0.25, 0.5, 0.75, 1.0 and 1.25 g/ 100 ml of oil) have been optimized by response surface methodology (RSM) considering percentage reduction of PV as a response. Adsorption data were analysed by fitting with Langmuir and Freundlich isotherm model. The results show that the Langmuir model shows the best fit compared to the Freundlich model. The adsorption process was also found to follow a pseudo-second-order kinetic model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bentonite" title="bentonite">bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=Langmuir%20isotherm" title=" Langmuir isotherm"> Langmuir isotherm</a>, <a href="https://publications.waset.org/abstracts/search?q=peroxide%20value" title=" peroxide value"> peroxide value</a>, <a href="https://publications.waset.org/abstracts/search?q=RSM" title=" RSM"> RSM</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean%20oil" title=" soybean oil"> soybean oil</a> </p> <a href="https://publications.waset.org/abstracts/44879/recovery-of-fried-soybean-oil-using-bentonite-as-an-adsorbent-optimization-isotherm-and-kinetics-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44879.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">375</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">1637</span> Diabatic Flow of Sub-Cooled R-600a Inside a Capillary Tube: Concentric Configuration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravi%20Kumar">Ravi Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Santhosh%20Kumar%20Dubba"> Santhosh Kumar Dubba </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an experimental study of a diabatic flow of R-600a through a concentric configured capillary tube suction line heat exchanger. The details of experimental facility for testing the diabatic capillary tube with different inlet sub-cooling degree and pressure are discussed. The effect of coil diameter, capillary length, capillary tube diameter, sub-cooling degree and inlet pressure on mass flow rate are presented. The degree of sub-cooling at the inlet of capillary tube is varied from 3-20°C. The refrigerant mass flow rate is scattered up with rising of pressure. A semi-empirical correlation to predict the mass flow rate of R-600a flowing through a diabatic capillary tube is proposed for sub-cooled inlet conditions. The proposed correlation predicts measured data with an error band of ±20 percent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabatic" title="diabatic">diabatic</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20tube" title=" capillary tube"> capillary tube</a>, <a href="https://publications.waset.org/abstracts/search?q=concentric" title=" concentric"> concentric</a>, <a href="https://publications.waset.org/abstracts/search?q=R-600a" title=" R-600a"> R-600a</a> </p> <a href="https://publications.waset.org/abstracts/81743/diabatic-flow-of-sub-cooled-r-600a-inside-a-capillary-tube-concentric-configuration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81743.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">204</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">1636</span> Diagnostic Investigation of Aircraft Performance at Different Winglet Cant Angles </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Dinesh">M.

In the parametric analytical studies, NACA series of airfoils are selected. Basic design of the winglet is selected from the literature and flow features of the entire wing including the winglet tip effects have been examined with different cant angles varying from 150 to 600 at different angles of attack up to 140. We have observed, among the cases considered in this study that a case with 150 cant angle the aerodynamics performance of the subsonic aircraft during takeoff was found better up to an angle of attack of 2.80 and further its performance got diminished at higher angles of attack. Analyses further revealed that increasing the winglet cant angle from 150 to 600 at higher angles of attack could negate the performance deterioration and additionally it could enhance the peak CL/CD on the order of 3.5%. The investigated concept of variable-cant-angle winglets appears to be a promising alternative for improving the aerodynamic efficiency of aircraft. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20efficiency" title="aerodynamic efficiency">aerodynamic efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=cant%20angle" title=" cant angle"> cant angle</a>, <a href="https://publications.waset.org/abstracts/search?q=drag%20reduction" title=" drag reduction"> drag reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20winglets" title=" flexible winglets "> flexible winglets </a> </p> <a href="https://publications.waset.org/abstracts/18421/diagnostic-investigation-of-aircraft-performance-at-different-winglet-cant-angles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18421.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">523</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">1635</span> Detecting Heartbeat Architectural Tactic in Source Code Using Program Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ananta%20Kumar%20%20Das">Ananta Kumar Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Sujit%20Kumar%20Chakrabarti"> Sujit Kumar Chakrabarti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Architectural tactics such as heartbeat, ping-echo, encapsulate, encrypt data are techniques that are used to achieve quality attributes of a system. Detecting architectural tactics has several benefits: it can aid system comprehension (e.g., legacy systems) and in the estimation of quality attributes such as safety, security, maintainability, etc. Architectural tactics are typically spread over the source code and are implicit. For large codebases, manual detection is often not feasible. Therefore, there is a need for automated methods of detection of architectural tactics. This paper presents a formalization of the heartbeat architectural tactic and a program analytic approach to detect this tactic in source code. The experiment of the proposed method is done on a set of Java applications. The outcome of the experiment strongly suggests that the method compares well with a manual approach in terms of its sensitivity and specificity, and far supersedes a manual exercise in terms of its scalability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20architecture" title="software architecture">software architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20tactics" title=" architectural tactics"> architectural tactics</a>, <a href="https://publications.waset.org/abstracts/search?q=detecting%20architectural%20tactics" title=" detecting architectural tactics"> detecting architectural tactics</a>, <a href="https://publications.waset.org/abstracts/search?q=program%20analysis" title=" program analysis"> program analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=AST" title=" AST"> AST</a>, <a href="https://publications.waset.org/abstracts/search?q=alias%20analysis" title=" alias analysis"> alias analysis</a> </p> <a href="https://publications.waset.org/abstracts/117825/detecting-heartbeat-architectural-tactic-in-source-code-using-program-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117825.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">160</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">1634</span> Implementation of MPPT Algorithm for Grid Connected PV Module with IC and P&O Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arvind%20Kumar">Arvind Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Kumar"> Manoj Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dattatraya%20H.%20Nagaraj"> Dattatraya H.

Photovoltaic generation is becoming increasingly important as a renewable resource since it does not cause in fuel costs, pollution, maintenance, and emitting noise compared with other alternatives used in power applications. In this paper, Perturb and Observe and Incremental Conductance methods are used to improve energy conversion efficiency under different environmental conditions. PI controllers are used to control easily DC-link voltage, active and reactive currents. The whole system is simulated under standard climatic conditions (1000 W/m2, 250C) in MATLAB and the irradiance is varied from 1000 W/m2 to 300 W/m2. The use of PI controller makes it easy to directly control the power of the grid connected PV system. Finally the validity of the system will be verified through the simulations in MATLAB/Simulink environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incremental%20conductance%20algorithm" title="incremental conductance algorithm">incremental conductance algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20of%20PV%20panel" title=" modeling of PV panel"> modeling of PV panel</a>, <a href="https://publications.waset.org/abstracts/search?q=perturb%20and%20observe%20algorithm" title=" perturb and observe algorithm"> perturb and observe algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20system%20and%20simulation%20results" title=" photovoltaic system and simulation results"> photovoltaic system and simulation results</a> </p> <a href="https://publications.waset.org/abstracts/11193/implementation-of-mppt-algorithm-for-grid-connected-pv-module-with-ic-and-po-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11193.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">509</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">1633</span> Investigation on the Performance and Emission Characteristics of Biodiesel (Animal Oil): Ethanol Blends in a Single Cylinder Diesel Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Veeresh%20Babu">A.

These can be obtained from various resources. However, the usage of biodiesel in high percentage in compression ignition may cause some technical problems because of their higher viscosity, high pour point, and low volatility. Ethanol can be used as a fuel extender to enable use of higher percentage of biodiesel in CI engine. Blends of ethanol-animal fat oil biodiesel-diesel have been prepared and experimental study has been carried out. We have found that B40E20 fuel blend (40% biodiesel and 20 % ethanol in diesel) reduces the specific fuel consumption and improves brake thermal efficiency of engine compared to B40 fuel blend. We observed that fuel characteristics improved considerably with addition of ethanol to biodiesel. Emissions of CO, HC and smoke were reduced while CO2 emissions were increased because of more complete combustion of the blend. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diesel" title="diesel">diesel</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title=" biodiesel"> biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=CI%20engine" title=" CI engine"> CI engine</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20performance" title=" engine performance"> engine performance</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20emission" title=" exhaust emission"> exhaust emission</a> </p> <a href="https://publications.waset.org/abstracts/24568/investigation-on-the-performance-and-emission-characteristics-of-biodiesel-animal-oil-ethanol-blends-in-a-single-cylinder-diesel-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24568.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">712</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">1632</span> In-Silico Investigation of Phytochemicals from Ocimum Sanctum as Plausible Antiviral Agent in COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dileep%20Kumar">Dileep Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Janhavi%20Ramchandra%20Rao%20Kumar"> Janhavi Ramchandra Rao Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rao"> Rao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> COVID-19 has ravaged the globe, and it is spreading its Spectre day by day. In the absence of established drugs, this disease has created havoc. Some of the infected persons are symptomatic or asymptomatic. The respiratory system, cardiac system, digestive system, etc. in human beings are affected by this virus. In our present investigation, we have undertaken a study of the Indian Ayurvedic herb, Ocimum sanctum against SARS-CoV-2 using molecular docking and dynamics studies. The docking analysis was performed on the Glide module of Schrödinger suite on two different proteins from SARS-CoV-2 viz. NSP15 Endoribonuclease and spike receptor-binding domain. MM-GBSA based binding free energy calculations also suggest the most favorable binding affinities of carvacrol, β elemene, and β caryophyllene with binding energies of −61.61, 58.23, and −54.19 Kcal/mol respectively with spike receptor-binding domain and NSP15 Endoribonuclease.

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">1630</span> A Two-Dimensional Problem Micropolar Thermoelastic Medium under the Effect of Laser Irradiation and Distributed Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Devinder%20Singh">Devinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajneesh%20Kumar"> Rajneesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Arvind%20Kumar"> Arvind Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present investigation deals with the deformation of micropolar generalized thermoelastic solid subjected to thermo-mechanical loading due to a thermal laser pulse.

A pre-experimental research design was used to conduct the study among the PLWA on ART at BPKIHS from June to August 2013 involving 60 PLWA on pre-test randomly. The mean age of the respondents was 36.70 ± 9.92, and majority of them (80%) were of age group of 25-50 years and Male (56.7%). After education intervention programme there is significant change in the QOL in all the four domains i.e. Physical (p=0.008), Psychological (p=0.019), Social (p=0.046) and Environmental (p=0.032) using student t-test at 0.05 level of significance. There is significant (p= 0.016) difference in the mean QOL scores of pre-test and post-test. High QOL scores in post-test after education intervention programme may reflective of the effectiveness of planned education interventions programme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=telephone" title="telephone">telephone</a>, <a href="https://publications.waset.org/abstracts/search?q=AIDS" title=" AIDS"> AIDS</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20service" title=" health service"> health service</a>, <a href="https://publications.waset.org/abstracts/search?q=Nepal" title=" Nepal"> Nepal</a> </p> <a href="https://publications.waset.org/abstracts/16608/telephone-health-service-to-improve-the-quality-of-life-of-the-people-living-with-aids-in-eastern-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16608.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">502</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">1628</span> A Combined Feature Extraction and Thresholding Technique for Silence Removal in Percussive Sounds </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Kishore%20Kumar">B.

In music analysis, the first step is to divide the music signal to different sections based on the feature profiles of the music signal. In this paper, we present a music segmentation technique that will effectively segmentize the signal and thresholding technique to remove silence from the percussive sounds produced by percussive instruments, which uses two features of music, namely signal energy and spectral centroid. The proposed method impose thresholds on both the features which will vary depends on the music signal. Depends on the threshold, silence part is removed and the segmentation is done.

The correlation between genes and samples has been regularly used to gain insight into many biological phenomena including, but not limited to, co-expression/co-regulation, gene regulatory networks, clustering and pattern identification. However, presence of outliers and violation of assumptions underlying Pearson correlation is frequent and may distort the actual correlation between the genes and lead to spurious conclusions. Here, we report a method to measure the strength of association between genes. The method assumes that the expression values of a gene are Bernoulli random variables whose outcome depends on the sample being probed. The method considers the two genes as uncorrelated if the number of sample with same outcome for both the genes (Ns) is equal to certainly expected number (Es). The extent of correlation depends on how far Ns can deviate from the Es. The method does not assume normality for the parent population, fairly unaffected by the presence of outliers, can be applied to qualitative data and it uses the binomial distribution to assess the significance of association. At this stage, we would not claim about the superiority of the method over other existing correlation methods, but our method could be another way of calculating correlation in addition to existing methods. The method uses binomial distribution, which has not been used until yet, to assess the significance of association between two variables. We are evaluating the performance of our method on NGS/microarray data, which is noisy and pierce by the outliers, to see if our method can differentiate between spurious and actual correlation. While working with the method, it has not escaped our notice that the method could also be generalized to measure the association of more than two variables which has been proven difficult with the existing methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binomial%20distribution" title="binomial distribution">binomial distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation" title=" correlation"> correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=microarray" title=" microarray"> microarray</a>, <a href="https://publications.waset.org/abstracts/search?q=outliers" title=" outliers"> outliers</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptome" title=" transcriptome"> transcriptome</a> </p> <a href="https://publications.waset.org/abstracts/60503/assessing-significance-of-correlation-with-binomial-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60503.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">415</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">1626</span> Efficacy of Collagen Matrix Implants in Phacotrabeculectomy with Mitomycin C at One Year</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lalit%20Tejwani">Lalit Tejwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Reetika%20Sharma"> Reetika Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Singhvi"> Arun Singhvi</a>, <a href="https://publications.waset.org/abstracts/search?q=Himanshu%20Shekhar"> Himanshu Shekhar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: To assess the efficacy of collagen matrix implant (Ologen) in phacotrabeculectomy augmented with mitomycin C (MMC). Methods: A biodegradable collagen matrix (Ologen) was placed in the subconjunctival and subscleral space in twenty-two eyes of 22 patients with glaucoma and cataract who underwent combined phacoemulsification and trabeculectomy augmented with MMC. All of them were examined preoperatively and on the first postoperative day. They were followed for twelve months after surgery. Any intervention needed in follow-up period was noted. Any complication was recorded. The primary outcome measure was postoperative intraocular pressure at one year follow-up. Any additional postoperative treatments needed and adverse events were noted. Results: The mean age of patients included in the study was 57.77 ± 9.68 years (range=36 to 70 years). All the patients were followed for at least one year. Three patients had history of failed trabeculectomy. Fifteen patients had chronic angle closure glaucoma with cataract, five had primary open angle glaucoma with cataract, one had uveitic glaucoma with cataract, and one had juvenile open angle glaucoma with cataract. Mean preoperative IOP was 32.63 ± 8.29 mm Hg, eighteen patients were on oral antiglaucoma medicines. The mean postoperative IOP was 10.09 ± 2.65 mm Hg at three months, 10.36 ± 2.19 mm Hg at six months and 11.36 ± 2.72 mm Hg at one year follow up. No adverse effect related to Ologen was seen. Anterior chamber reformation was done in five patients, and three needed needling of bleb. Four patients needed additional antiglaucoma medications in the follow-up period. Conclusions: Combined phacotrabeculectomy with MMC with Ologen implantation appears to be a safe and effective option in glaucoma patients needing trabeculectomy with significant cataract. Comparative studies with longer duration of follow-up in larger number of patients are needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combined%20surgery" title="combined surgery">combined surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=ologen" title=" ologen"> ologen</a>, <a href="https://publications.waset.org/abstracts/search?q=phacotrabeculectomy" title=" phacotrabeculectomy"> phacotrabeculectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=success" title=" success"> success</a> </p> <a href="https://publications.waset.org/abstracts/75958/efficacy-of-collagen-matrix-implants-in-phacotrabeculectomy-with-mitomycin-c-at-one-year" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75958.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">213</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">1625</span> Role of Ologen in Previously Failed Trabeculectomy in Advanced Glaucoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reetika%20Sharma">Reetika Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Lalit%20Tejwani"> Lalit Tejwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Himanshu%20Shekhar"> Himanshu Shekhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Singhvi"> Arun Singhvi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Advanced Glaucoma with Failed trab is not an uncommon sight in glaucoma clinic, and such cases usually tend to present with high intraocular pressure (IOP) and advanced cupping, or even glaucomatous atrophy stage. Re-surgery is needed for such cases, and wound modulation poses a major challenge in these cases. We share our experience in this case series with the use of Ologen (collagen matrix implant) along with MMC 0.04% used in surgery. The purpose of the study was to evaluate the efficacy and outcome of collagen matrix implant in re-trabeculectomy in advanced glaucoma cases. Methodology: Eleven eyes of 11 patients (one eye of one patient) underwent re-trabeculectomy surgery with MMC and Ologen. Ologen implant was used in sub scleral and subconjunctival space, as a spacer and wound modulator. In five cases, triple modulation with implant soaked in anti-VEGF was used. Results: All patients had cupping more than 0.9, and one case was GOA. All cases were on maximal medication at presentation and majority were on systemic anti-glaucoma therapy also. Post-surgery, follow-up ranged from 13 – 34 months, and all cases had a follow longer than the gap between previous surgery (which was failed) and re-trab. One case needed AC reformation and one needling was done. Phaco was done at same sitting in four cases. All cases had their IOP lowered post surgery, and vision was maintained in all, however one case was considered as failed re-surgery case. Topical medication was needed in seven cases post-surgery also. Conclusion: Ologen as adjuvant should be considered in all re-trab cases and all high risk and advanced cases, and triple modulation can be next step in these cases. Aggressive IOP control and non- reluctance to continue topical medications post second surgery should be considered in such cases, to give them best possible vision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failed%20trabeculectomy" title="failed trabeculectomy">failed trabeculectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=ologen" title=" ologen"> ologen</a>, <a href="https://publications.waset.org/abstracts/search?q=trabeculectomy" title=" trabeculectomy"> trabeculectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20glaucoma" title=" advanced glaucoma"> advanced glaucoma</a> </p> <a href="https://publications.waset.org/abstracts/75961/role-of-ologen-in-previously-failed-trabeculectomy-in-advanced-glaucoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75961.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">335</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">1624</span> Overview and Post Damage Analysis of Nepal Earthquake 2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vipin%20Kumar%20Singhal">Vipin Kumar Singhal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Kumar%20Mittal"> Rohit Kumar Mittal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavitra%20Ranjan%20Maiti"> Pavitra Ranjan Maiti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Damage analysis is one of the preliminary activities to be done after an earthquake so as to enhance the seismic building design technologies and prevent similar type of failure in future during earthquakes. This research article investigates the damage pattern and most probable reason of failure by observing photographs of seven major buildings collapsed/damaged which were evenly spread over the region during Mw7.8, Nepal earthquake 2015 followed by more than 400 aftershocks of Mw4 with one aftershock reaching a magnitude of Mw7.3. Over 250,000 buildings got damaged, and more than 9000 people got injured in this earthquake. Photographs of these buildings were collected after the earthquake and the cause of failure was estimated along with the severity of damage and comment on the reparability of structure has been made. Based on observations, it was concluded that the damage in reinforced concrete buildings was less compared to masonry structures. The number of buildings damaged was high near Kathmandu region due to high building density in that region. This type of damage analysis can be used as a cost effective and quick method for damage assessment during earthquakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nepal%20earthquake" title="Nepal earthquake">Nepal earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20analysis" title=" damage analysis"> damage analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20assessment" title=" damage assessment"> damage assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20scales" title=" damage scales"> damage scales</a> </p> <a href="https://publications.waset.org/abstracts/54094/overview-and-post-damage-analysis-of-nepal-earthquake-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54094.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">374</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">1623</span> Volatility Spillover Among the Stock Markets of South Asian Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Aziz">Tariq Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Kumar"> Suresh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikesh%20Kumar"> Vikesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheraz%20Mustafa"> Sheraz Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhanzeb%20Marwat"> Jhanzeb Marwat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper provides an updated version of volatility spillover among the equity markets of South Asian countries, including Pakistan, India, Srilanka, and Bangladesh.

The bivariate EGARCH model is used to test for volatility transmission between two equity markets. Weekly data for the period February 2013 to August 2019 is used for empirical analysis. The findings indicate that the leverage effect exists in the equity markets of all the countries except Bangladesh. The volatility spillover from the equity market of Bangladesh to all other countries is negative and significant whereas the volatility of the equity market of Sri-Lanka does influence the volatility of any other country’s equity market. Indian equity market influence only the volatility of the Sri-Lankan equity market; and there is bidirectional volatility spillover between the equity markets of Pakistan and Bangladesh.

The present study was carried out to understand the relationship between productivity in the cages and water depth. The experiment was conducted in the fish cages installed in the pond at the Directorate of Sustainable Aquaculture, Thanjavur, Tamil Nadu Dr. J. Jayalalithaa Fisheries University, Tamil Nadu (10° 47' 13.1964'' N; 79° 8' 16.1700''E). Primary productivity was estimated by light and dark bottle method. The measurement of primary productivity was done at different depths viz., 20 cm, 40 cm, and 60 cm. Six Biological Oxygen Demand bottles of 300 ml capacity were collected and tagged. The productivity was obtained in mg O2/l/hr. The maximum dissolved oxygen level at 20 cm depth was observed 5.62 ± 0.22 mg/l/hr in the light bottle in pond water while the minimum dissolved oxygen level at 20 cm depth in a cage was observed 3.62 ± 0.18 mg/l/hr in dark bottle. In the same way, the maximum and minimum value of dissolved oxygen was observed at 40, and 60 cm depth and results were compared. A slight change in pH was observed in the cage and pond. The maximum gross primary productivity observed was 1.97 mg/l/hr in pond at 20 cm depth while minimum gross primary productivity observed was 0.82±0.16 mg/l/hr in a cage at 60 cm depth. The community respiration was also variable with the depth in both cage and pond. Maximum community respiration was found 1.50±0.19 mg/l/hr in pond at 20 cm depth. A strong positive linear relationship was observed between primary productivity and fish yields in ponds. The pond primary productivity can contribute substantially to the nutrition of farm-raised aquaculture species, including shrimp. The growth of phytoplankton’s is dependent on the sun light, availability of primary nutrients (N, P, and K) in the water body and transparency, so to increase the primary productivity fertilization through organic manure may be done that will clean to the pond environment also. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cage%20aquaculture" title="cage aquaculture">cage aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20depth" title=" water depth"> water depth</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20primary%20productivity" title=" net primary productivity"> net primary productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20primary%20productivity" title=" gross primary productivity"> gross primary productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20respiration" title=" community respiration"> community respiration</a> </p> <a href="https://publications.waset.org/abstracts/119278/a-comparative-study-on-primary-productivity-in-fish-cage-culture-unit-and-fish-pond-in-relation-to-different-level-of-water-depth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119278.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">208</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">1621</span> A Multi Sensor Monochrome Video Fusion Using Image Quality Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Prema%20Kumar">M.

This paper gives a novel approach of merging the information content from several videos taken from the same scene in order to rack up a combined video that contains the finest information coming from different source videos. This process is known as video fusion which helps in providing superior quality (The term quality, connote measurement on the particular application.) image than the source images. In this technique different sensors (whose redundant information can be reduced) are used for various cameras that are imperative for capturing the required images and also help in reducing. In this paper Image fusion technique based on multi-resolution singular value decomposition (MSVD) has been used. The image fusion by MSVD is almost similar to that of wavelets. The idea behind MSVD is to replace the FIR filters in wavelet transform with singular value decomposition (SVD). It is computationally very simple and is well suited for real time applications like in remote sensing and in astronomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi%20sensor%20image%20fusion" title="multi sensor image fusion">multi sensor image fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=MSVD" title=" MSVD"> MSVD</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=monochrome%20video" title=" monochrome video"> monochrome video</a> </p> <a href="https://publications.waset.org/abstracts/14866/a-multi-sensor-monochrome-video-fusion-using-image-quality-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14866.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">572</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">1620</span> Economical Analysis of Optimum Insulation Thickness for HVAC Duct</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Kumar">D.

In this paper, the economic impact of compression of insulation is estimated. Relevant mathematical models were used to estimate the optimal thickness at the points of compression. Furthermore, the payback period is calculated for the optimal thickness at the critical parts of supply air duct (SAD) and return air duct (RAD) considering natural gas (NG) and liquefied petroleum gas (LPG) as fuels for chillier operation. The mathematical model is developed using preliminary data obtained for an HVAC system of a pharmaceutical company. The higher heat gain and cooling loss, due to compression of thermal insulation, is estimated using relevant heat transfer equations. The results reveal that maximum energy savings (ES) in SAD is 34.5 and 40%, while in RAD is 22.9% and 29% for NG and LPG, respectively. Moreover, the minimum payback period (PP) for SAD is 2 and 1.6years, while in RAD is 4.3 and 2.7years for NG and LPG, respectively. The optimum insulation thickness (OIT) corresponding to maximum ES and minimum PP is estimated to be 35 and 42mm for SAD, while 30 and 38mm for RAD in case of NG and LPG, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimum%20insulation%20thickness" title="optimum insulation thickness">optimum insulation thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20cost%20analysis" title=" life cycle cost analysis"> life cycle cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=payback%20period" title=" payback period"> payback period</a>, <a href="https://publications.waset.org/abstracts/search?q=HVAC%20system" title=" HVAC system"> HVAC system</a> </p> <a href="https://publications.waset.org/abstracts/92533/economical-analysis-of-optimum-insulation-thickness-for-hvac-duct" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92533.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">216</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">1619</span> Managing the Cosmos: Problems, Solutions, and Future Insights into Space Debris</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irfan%20Nazir%20Wani">Irfan Nazir Wani</a>, <a href="https://publications.waset.org/abstracts/search?q=Pushpendra%20Kumar%20Shukla"> Pushpendra Kumar Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Kumar"> Manoj Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Debris, also called waste or junk, present in orbit of Earth or orbital debris, offers a substantial challenge to space exploration.

Using different types of equipments driven manually or by powered, machines make the soil suitable to place the seeds into the desirable depth. Moreover, tillage loosens the compacted layers. Heavy equipment and tillage implements can cause damage to the soil structure. Effect of various tillage methods on soil compaction was studied in Rabi season of 2013-14 at village Ladwa, Hisar, Haryana (India). The experiments studied the effect of six tillage treatments i.e. no tillage or zero tillage (T1), tillage with rotavator (T2), disc harrow (T3), rotavator + sub soiler (T4), disc harrow + sub soiler (T5) and power harrow (T6) on soil compaction. Soil compaction was measured before tillage and after sowing at 0, 30, 60 and 90 days after sowing. No change in soil resistance was recorded before and after no tillage treatment. Maximum soil resistance was found in zero tillage followed by disc harrow up to 150 mm soil depth. Minimum soil resistance was found in rotavator immediately after the tillage treatment. However, the soil resistance approached the same level as it had been before the tillage after the soil strata where the implement cannot reach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tillage" title="tillage">tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=no%20tillage" title=" no tillage"> no tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=rotavator" title=" rotavator"> rotavator</a>, <a href="https://publications.waset.org/abstracts/search?q=subsoiler" title=" subsoiler"> subsoiler</a>, <a href="https://publications.waset.org/abstracts/search?q=compaction" title=" compaction"> compaction</a> </p> <a href="https://publications.waset.org/abstracts/92819/effect-of-various-tillage-systems-on-soil-compaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92819.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">318</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">1617</span> Traction Behavior of Linear Piezo-Viscous Lubricants in Rough Elastohydrodynamic Lubrication Contacts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Punit%20Kumar">Punit Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Niraj%20Kumar"> Niraj Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The traction behavior of lubricants with the linear pressure-viscosity response in EHL line contacts is investigated numerically for smooth as well as rough surfaces. The analysis involves the simultaneous solution of Reynolds, elasticity and energy equations along with the computation of lubricant properties and surface temperatures. The temperature modified Doolittle-Tait equations are used to calculate viscosity and density as functions of fluid pressure and temperature, while Carreau model is used to describe the lubricant rheology. The surface roughness is assumed to be sinusoidal and it is present on the nearly stationary surface in near-pure sliding EHL conjunction. The linear P-V oil is found to yield much lower traction coefficients and slightly thicker EHL films as compared to the synthetic oil for a given set of dimensionless speed and load parameters. Besides, the increase in traction coefficient attributed to surface roughness is much lower for the former case. The present analysis emphasizes the importance of employing realistic pressure-viscosity response for accurate prediction of EHL traction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EHL" title="EHL">EHL</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20pressure-viscosity" title=" linear pressure-viscosity"> linear pressure-viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=traction" title=" traction"> traction</a>, <a href="https://publications.waset.org/abstracts/search?q=water%2Fglycol" title=" water/glycol"> water/glycol</a> </p> <a href="https://publications.waset.org/abstracts/50474/traction-behavior-of-linear-piezo-viscous-lubricants-in-rough-elastohydrodynamic-lubrication-contacts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50474.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">382</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">1616</span> Host-Assisted Delivery of a Model Drug to Genomic DNA: Key Information From Ultrafast Spectroscopy and in Silico Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ria%20Ghosh">Ria Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumendra%20Singh"> Soumendra Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dipanjan%20Mukherjee"> Dipanjan Mukherjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Susmita%20Mondal"> Susmita Mondal</a>, <a href="https://publications.waset.org/abstracts/search?q=Monojit%20Das"> Monojit Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Uttam%20Pal"> Uttam Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Aniruddha%20Adhikari"> Aniruddha Adhikari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aman%20Bhushan"> Aman Bhushan</a>, <a href="https://publications.waset.org/abstracts/search?q=Surajit%20Bose"> Surajit Bose</a>, <a href="https://publications.waset.org/abstracts/search?q=Siddharth%20Sankar%20Bhattacharyya"> Siddharth Sankar Bhattacharyya</a>, <a href="https://publications.waset.org/abstracts/search?q=Debasish%20Pal"> Debasish Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanusri%20Saha-Dasgupta"> Tanusri Saha-Dasgupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Maitree%20Bhattacharyya"> Maitree Bhattacharyya</a>, <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Bhattacharyya"> Debasis Bhattacharyya</a>, <a href="https://publications.waset.org/abstracts/search?q=Asim%20Kumar%20Mallick"> Asim Kumar Mallick</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Das"> Ranjan Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Kumar%20Pal"> Samir Kumar Pal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drug delivery to a target without adverse effects is one of the major criteria for clinical use. Herein, we have made an attempt to explore the delivery efficacy of SDS surfactant in a monomer and micellar stage during the delivery of the model drug, Toluidine Blue (TB) from the micellar cavity to DNA. Molecular recognition of pre-micellar SDS encapsulated TB with DNA occurs at a rate constant of k1 ~652 s 1. However, no significant release of encapsulated TB at micellar concentration was observed within the experimental time frame. This originated from the higher binding affinity of TB towards the nano-cavity of SDS at micellar concentration which does not allow the delivery of TB from the nano-cavity of SDS micelles to DNA. Thus, molecular recognition controls the extent of DNA recognition by TB which in turn modulates the rate of delivery of TB from SDS in a concentration-dependent manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA" title="DNA">DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=micelle" title=" micelle"> micelle</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-micelle" title=" pre-micelle"> pre-micelle</a>, <a href="https://publications.waset.org/abstracts/search?q=SDS" title=" SDS"> SDS</a>, <a href="https://publications.waset.org/abstracts/search?q=toluidine%20blue" title=" toluidine blue"> toluidine blue</a> </p> <a href="https://publications.waset.org/abstracts/154090/host-assisted-delivery-of-a-model-drug-to-genomic-dna-key-information-from-ultrafast-spectroscopy-and-in-silico-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154090.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">113</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">1615</span> Measurement of Operational and Environmental Performance of the Coal-Fired Power Plants in India by Using Data Envelopment Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Kumar%20Bajpai">Vijay Kumar Bajpai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudhir%20Kumar%20Singh"> Sudhir Kumar Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the performance analyses of the twenty five coal-fired power plants (CFPPs) used for electricity generation are carried out through various data envelopment analysis (DEA) models. Three efficiency indices are defined and pursued. During the calculation of the operational performance, energy and non-energy variables are used as input, and net electricity produced is used as desired output. CO2 emitted to the environment is used as the undesired output in the computation of the pure environmental performance while in Model-3 CO2 emissions is considered as detrimental input in the calculation of operational and environmental performance. Empirical results show that most of the plants are operating in increasing returns to scale region and Mettur plant is efficient one with regards to energy use and environment. The result also indicates that the undesirable output effect is insignificant in the research sample. The present study will provide clues to plant operators towards raising the operational and environmental performance of CFPPs. <p class="card-text"><strong>Keywords:</strong> <a
