Vahdani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By the adsorption of polar compounds and/or the deposition of organic material, the wettability of originally water-wet reservoir rock can be altered. The degree of alteration is determined by the interaction of the oil constituents, the mineral surface, and the brine chemistry. Recently improving oil recovery by tuning wettability alteration is believed as a new recovery method. Various researchers have demonstrated that low salt water injection has a significant impact on oil recovery. It has been shown, for instance, that additional oil can be produced from reservoir rock by managing the injection water. Large wettability sensitivity has been observed, indicating that the oil/water capillary pressure profiles play a major role during low saline water injection simulation. Although the exact physics on how this alteration occurs is still a research topic; however, it has been reported that some of its effect can be captured by a relative permeability shift from an oil-wet system to a water-wet system. Modeling of low salt water injection mainly is based on the theory of wettability alteration and is hence strongly dependent on the wettability of the reservoir. In this article, combination of different wettabilities has been simulated and it is observed that the highest recoveries were from the cases were the reservoir initially was water-wet, and the lowest recoveries was from the cases were the reservoir initially was considered oil-wet. However for the cases where the reservoir initially was oil-wet, the effect of low-salinity waterflooding was the largest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20salt%20water%20injection" title="low salt water injection">low salt water injection</a>, <a href="https://publications.waset.org/abstracts/search?q=wettability%20alteration" title=" wettability alteration"> wettability alteration</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20permeability" title=" relative permeability"> relative permeability</a> </p> <a href="https://publications.waset.org/abstracts/33827/effect-of-wettability-alteration-in-low-salt-water-injection-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33827.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">495</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">1027</span> Energy Efficient Alternate Hydraulic System Called TejHydroLift</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tejinder%20Singh">Tejinder Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a new more efficient Hydraulic System which uses lesser work to produce more output.

These investigations are further more important for components with complex profile, since there is no direct correlation available in literature to evaluate the hydraulic characteristics of such components directly. In those cases available correlations for similar profile or geometries may lead to significant uncertainty in the outcome. Hence experimental approach can be adopted to evaluate these hydraulic characteristics more precisely for better prediction in reactor core components. Prototype Fast Breeder Reactor (PFBR), a sodium cooled pool type reactor is under advanced stage of construction at Kalpakkam, India. Several components of this reactor core require hydraulic investigation before its usage in the reactor. These hydraulic investigations on full scale models, carried out by experimental approaches using water as simulant fluid are discussed in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20breeder%20reactor" title="fast breeder reactor">fast breeder reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=cavitation" title=" cavitation"> cavitation</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20drop" title=" pressure drop"> pressure drop</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20components" title=" reactor components"> reactor components</a> </p> <a href="https://publications.waset.org/abstracts/2579/hydraulic-studies-on-core-components-of-pfbr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2579.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">463</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">1024</span> Petrology and Hydrothermal Alteration Mineral Distribution of Wells La-9D and La-10D in Aluto Geothermal Field, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Moges%20Azbite">Dereje Moges Azbite</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laboratory analysis of igneous rocks is performed with the help of the main oxide plots.

Recently, main control valve (MCV) which is composed of several independent metering valve (IMV) has been introduced for better energy efficiency of the hydraulic system so that fuel efficiency of the excavator can be improved. Excavator with IMV has 5 operating modes depending on the quantity of regeneration flow. In this system, the hydraulic pump is controlled to supply demanded flow which is needed to operate each mode. Because the regenerated flow supply energy to actuators, the hydraulic pump consumes less energy to make same motion than one that does not regenerate flow. The horse power control is applied to the hydraulic pump of excavator for maintaining engine start under a heavy load and this control makes the flow of hydraulic pump reduced. When excavator is in complex operation such as loading or unloading soil, the hydraulic pump discharges small quantity of working fluid in high pressure. At this operation, the engine of excavator does not run at optimal operating line (OOL). The engine needs to be operated on OOL to improve fuel efficiency and by controlling hydraulic pump the engine can drive on OOL. By continuous mode changing of IMV, the hydraulic pump is controlled to make engine runs on OOL. The simulation result of this study shows that fuel efficiency of excavator with IMV can be improved by considering engine OOL and continuous mode changing algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20mode%20changing" title="continuous mode changing">continuous mode changing</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20fuel%20consumption" title=" engine fuel consumption"> engine fuel consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=excavator" title=" excavator"> excavator</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20efficiency" title=" fuel efficiency"> fuel efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=IMV" title=" IMV"> IMV</a> </p> <a href="https://publications.waset.org/abstracts/89388/energy-efficiency-improvement-of-excavator-with-independent-metering-valve-by-continuous-mode-changing-considering-engine-fuel-consumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89388.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">385</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">1021</span> Petrology and Hydrothermal Alteration Mineral Distribution of Wells LA-9D and LA-10D in Aluto Geothermal Field, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Moges%20Azbite">Dereje Moges Azbite</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laboratory analysis of igneous rocks is performed with the help of the main oxide plots.

Determination of hydraulic conductivity is a routine procedure for regular aggregate base courses. However, in many cases, a cement-stabilized base course is used with compromised drainage ability. Traditional hydraulic conductivity testing procedure is a readily available option which leads to two consequential drawbacks, i.e., the time required for the specimen to be saturated and extruding the sample after completion of the laboratory test. To overcome these complications, this study aims at formulating an empirical approach to predicting hydraulic conductivity based on Unconfined Compressive Strength test results. To do so, this study comprises two separate experiments (Constant Head Permeability test and Unconfined Compressive Strength test) conducted concurrently on a specimen having the same physical credentials. Data obtained from the two experiments were then used to devise a correlation between hydraulic conductivity and unconfined compressive strength. This correlation in the form of a polynomial equation helps to predict the hydraulic conductivity of cement-treated pavement base course, bypassing the cumbrous process of traditional permeability and less commonly used horizontal permeability tests. The correlation was further corroborated by a different set of data, and it has been found that the derived polynomial equation is deemed to be a viable tool to predict hydraulic conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20conductivity" title="hydraulic conductivity">hydraulic conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=unconfined%20compressive%20strength" title=" unconfined compressive strength"> unconfined compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20plastics" title=" recycled plastics"> recycled plastics</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20concrete%20aggregates" title=" recycled concrete aggregates"> recycled concrete aggregates</a> </p> <a href="https://publications.waset.org/abstracts/163967/hydraulic-conductivity-prediction-of-cement-stabilized-pavement-base-incorporating-recycled-plastics-and-recycled-aggregates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163967.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">90</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">1019</span> Effects of Climate Change on Hydraulic Design Methods of Railway Infrastructures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Cesali">Chiara Cesali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of climate change are increasingly evident: increases in temperature (i.e. global warming), greater frequency of extreme weather events, i.e. storms, floods, which often affect transport infrastructures. Large-scale climatological models with long-term horizons (up to 2100) show the possibility of significant increases in precipitation in the future, according to the greenhouse gas emissions scenarios from IPCC. Consequently, the insufficiency of existing hydraulic works (i.e. bridges, culverts, drainage systems) may be more frequent, or those currently being designed may become insufficient in the future. Thus, the hydraulic design methods of transport infrastructure must begin to take into account the influence of climate change. To this purpose, criteria for applying to the hydraulic design of a railway infrastructure some of the approaches currently available for determining design rainfall intensity and/or peak discharge flow on the basis of possible climate change scenarios are defined and proposed in the paper.

We consider a deregulated electrical industry where certain demand is satisfied by hydraulic and thermal technologies. The hydraulic operator decides the production in each season of each period that maximizes the sum of expected profits from power generation with respect to the stochastic dynamic constraint on the water stored in the dam, the environmental constraint and the non-negative output constraint. In contrast, the thermal plant is operated with quadratic cost function, with respect to the capacity production constraint and the non-negativity output constraint. We show that under imperfect competition, the hydraulic operator has a strategic storage of water in the peak season. Then, we quantify the strategic inter-annual and intra-annual water transfer and compare the numerical results. Finally, we show that the thermal operator can restrict the hydraulic output without compensation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20risk%20aversion" title="asymmetric risk aversion">asymmetric risk aversion</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20wholesale%20market" title=" electricity wholesale market"> electricity wholesale market</a>, <a href="https://publications.waset.org/abstracts/search?q=hydropower%20dams" title=" hydropower dams"> hydropower dams</a>, <a href="https://publications.waset.org/abstracts/search?q=imperfect%20competition" title=" imperfect competition"> imperfect competition</a> </p> <a href="https://publications.waset.org/abstracts/38733/hydraulic-resources-management-under-imperfect-competition-with-thermal-plants-in-the-wholesale-electricity-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38733.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">359</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">1017</span> Effect of Modeling of Hydraulic Form Loss Coefficient to Break on Emergency Core Coolant Bypass </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young%20S.%20Bang">Young S.

A hydraulic form loss coefficient (HFLC) from the reactor vessel downcomer to the broken cold leg is predicted by the computational fluid dynamics (CFD) code with a variation of the void fraction incoming from the downcomer. The maximum, mean, and minimum values of FLC are derived from the CFD results and are incorporated into the LBLOCA calculation using a system thermal-hydraulic code, MARS-KS.

Both subcritical and supercritical regimes are considered. Generally, when considering the theoretical problem of the free-surface flow, in a fluid domain of finite depth, due to the presence of an obstacle, we suppose that the water is an inviscid fluid, which means that there is no sheared velocity profile, but constant upstream. In a hydraulic channel, it is impossible to satisfy this condition. Indeed, water is a viscous fluid and its velocity is null at the bottom. The two configurations are presented, i.e. a flow over an obstacle and a towed obstacle in a resting fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experiments" title="experiments">experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=free-surface%20flow" title=" free-surface flow"> free-surface flow</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20channel" title=" hydraulic channel"> hydraulic channel</a>, <a href="https://publications.waset.org/abstracts/search?q=subcritical%20regime" title=" subcritical regime"> subcritical regime</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20flow" title=" supercritical flow"> supercritical flow</a> </p> <a href="https://publications.waset.org/abstracts/75299/on-the-free-surface-generated-by-the-flow-over-an-obstacle-in-a-hydraulic-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75299.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">307</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">1015</span> The Rehabilitation Solutions for the Hydraulic Jump Sweepout: A Case Study from India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Heidari">Ali Heidari</a>, <a href="https://publications.waset.org/abstracts/search?q=Hany%20Saleem"> Hany Saleem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tailwater requirements are important criteria in the design of the stilling basins as energy dissipation of the spillways. The adequate tailwater level that ensures the hydraulic jump inside the basin should be fulfilled by the river's natural water level and the apron depth downstream of the chute. The requirements of the hydraulic jump should mainly be checked for the design flood, however, the drawn jump condition should not be critical in the discharges lesser than the design flood. The tailwater requirement is not met in Almatti dam, built in 2005 in India, and the jump sweep out from the basin, resulting in significant scour in the apron and end sill of the basin. This paper discusses different hydraulic solutions as sustainable solutions for the rehabilitation program. The deep apron alternative is proposed for the fewer bays of the spillway as the most cost-effective, sustainable solution. The apron level of 15 gates out of 26 gates should decrease by 5.4 m compared to the existing design to ensure a safe hydraulic jump up to the discharge of 10,000 m3/s i.e. 30% of the updated PMF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dam" title="dam">dam</a>, <a href="https://publications.waset.org/abstracts/search?q=spillway" title=" spillway"> spillway</a>, <a href="https://publications.waset.org/abstracts/search?q=stilling%20basin" title=" stilling basin"> stilling basin</a>, <a href="https://publications.waset.org/abstracts/search?q=Almatti" title=" Almatti"> Almatti</a> </p> <a href="https://publications.waset.org/abstracts/185223/the-rehabilitation-solutions-for-the-hydraulic-jump-sweepout-a-case-study-from-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185223.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">57</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">1014</span> Construction of a Radial Centrifuge Pump for Agricultural Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmo%20Thiago%20Lins%20C%C3%B6uras%20Ford">Elmo Thiago Lins Cöuras Ford</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Alessandra%20Carvalho%20do%20Vale"> Valentina Alessandra Carvalho do Vale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the evolution of the productive processes, demonstrated mainly by the presence every time larger of the irrigation and to crescent it disputes for water, accompanied by your shortage (distances every time larger), there is need to project facilities that can provide supply of water with larger speed and efficiency.

Advanced methods have been used to measure and record laboratory experiments, to ensure accurate analysis and evaluation. Experiments have been conducted under different values of temperature (28, 40 and 50 °C), supply pressure (10, 20, 30, 40 and 50 bar), system stiffness (32 N/mm), and load (0.0 & 5560 N). It is concluded that increasing temperature of hydraulic oil increases the quantity of flow rate, so it achieves an increase of the quantity of flow by 5.75 % up to 48.8 % depending on operating conditions. The values of pressure decay at low temperature are less than the values at high temperature. The frequency increases with the increase of the temperature. When we connect the springs to the system, it decreases system frequency. These results are very useful in the process of packing and manufacturing of fluid products, where the properties are not affected by 50 °C, so energy and time are saved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electro-hydraulic%20servo%20valve" title="electro-hydraulic servo valve">electro-hydraulic servo valve</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20power%20control%20system" title=" fluid power control system"> fluid power control system</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20stiffness" title=" system stiffness"> system stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20and%20dynamic%20performance" title=" static and dynamic performance"> static and dynamic performance</a> </p> <a href="https://publications.waset.org/abstracts/98470/calibrations-and-effect-of-different-operating-conditions-on-the-performance-of-a-fluid-power-control-system-with-servo-solenoid-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98470.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">155</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">1011</span> Power Generation from Sewage by a Micro-Hydraulic Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomomi%20Uchiyama">Tomomi Uchiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomoko%20Okayama"> Tomoko Okayama</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukio%20Ide"> Yukio Ide</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is concerned with the development of a micro-hydraulic turbine for power generation installed in sewer pipes.

Many surfactants have been studied for this application. However, the importance of wettability alteration in sandstone reservoirs by surfactant has been poorly studied. In this paper, our recent study of the relationship between rock surface wettability and cumulative oil recovery for sandstone cores is reported. In our research, it has been found there is a good agreement between the wettability and oil recovery. Nonionic surfactants, Tomadol® 25-12 and Tomadol® 45-13, are very effective in wettability alteration of sandstone core surface from highly oil-wet conditions to water-wet conditions. By spontaneous imbibition test, Interfacial tension, and contact angle measurement these two surfactants exhibit the highest recovery of the synthetic oil made with heavy oil. Based on these experimental results, we can further conclude that the contact angle measurement and imbibition test can be used as rapid screening tools to identify better EOR surfactants to increase heavy oil recovery from sandstone reservoirs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EOR" title="EOR">EOR</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20gas" title=" oil gas"> oil gas</a>, <a href="https://publications.waset.org/abstracts/search?q=IOR" title=" IOR"> IOR</a>, <a href="https://publications.waset.org/abstracts/search?q=WC" title=" WC"> WC</a>, <a href="https://publications.waset.org/abstracts/search?q=IF" title=" IF"> IF</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20and%20gas" title=" oil and gas"> oil and gas</a> </p> <a href="https://publications.waset.org/abstracts/151355/surfactant-improved-heavy-oil-recovery-in-sandstone-reservoirs-by-wettability-alteration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151355.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">103</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">1009</span> Numerical Study on the Cavity-Induced Piping Failure of Embankment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20J.%20Kim">H.

Cavity reduces seepage length significantly and consequently causes piping failure of embankments. Case studies of embankment failures indicate that the relative settlement between ground and pile supported-concrete conduit was the main reason of the cavity. In this paper, an attempt to simulate the cavity-induced piping failure mechanism was made using finite element numerical method. Piping potential is examined by carrying out parametric study for influencing factors such as cavity length, water level, and flow conditions. The concentration of hydraulic gradient adjacent to cavity was found. It is found that the hydraulic gradient close to the cavity exceeds considerably the critical hydraulic gradient causing piping. Piping failure potential due to the existence of cavity is evaluated and contour map for the potential risk of an embankment for piping failure is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavity" title="cavity">cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20gradient" title=" hydraulic gradient"> hydraulic gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=levee" title=" levee"> levee</a>, <a href="https://publications.waset.org/abstracts/search?q=piping" title=" piping"> piping</a> </p> <a href="https://publications.waset.org/abstracts/33770/numerical-study-on-the-cavity-induced-piping-failure-of-embankment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33770.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">520</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">1008</span> Evaluation on Mechanical Stabilities of Clay-Sand Mixtures Used as Engineered Barrier for Radioactive Waste Disposal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20E.%20Osmanlioglu">Ahmet E.

In this research, bentonite is the subject of an analysis from standpoint of assessing the basic properties of engineered barriers with respect to the buffer material. Bentonite and sand mixtures were prepared for tests. Some of clay minerals give relatively higher hydraulic conductivity and lower swelling pressure. Generally, hydraulic conductivity of these type clays is lower than <10-12 m/s. The hydraulic properties of clay-sand mixtures are evaluated to design engineered barrier specifications. Hydraulic conductivities of bentonite-sand mixture were found in the range of 1.2x10-10 to 9.3x10-10 m/s. Optimum B/S mixture ratio was determined as 35% in terms of hydraulic conductivity and mechanical stability. At the second stage of this study, all samples were compacted into cylindrical shape molds (diameter: 50 mm and length: 120 mm). The strength properties of compacted mixtures were better than the compacted bentonite. In addition, the larger content of the quartz sand in the mixture has the greater thermal conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineered%20barriers" title="engineered barriers">engineered barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20stability" title=" mechanical stability"> mechanical stability</a>, <a href="https://publications.waset.org/abstracts/search?q=clay" title=" clay"> clay</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20waste%20disposal" title=" nuclear waste disposal"> nuclear waste disposal</a> </p> <a href="https://publications.waset.org/abstracts/43160/evaluation-on-mechanical-stabilities-of-clay-sand-mixtures-used-as-engineered-barrier-for-radioactive-waste-disposal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43160.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">384</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">1007</span> Hardware in the Loop Platform for Virtual Commissioning: Case Study of a Hydraulic-Press Model Simulated in Real-Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Rodriguez-Guerra">Jorge Rodriguez-Guerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Calleja"> Carlos Calleja</a>, <a href="https://publications.waset.org/abstracts/search?q=Aron%20Pujana"> Aron Pujana</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Maria%20Macarulla"> Ana Maria Macarulla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydraulic-press commissioning consumes a great amount of man-hours, due to the fact that it takes place several miles away from where it has been designed. This factor became exacerbated due to control designers’ lack of knowledge about which will be the final controller gains before they start working with it. Virtual commissioning has been postulated as an optimal solution to deal with this lack of knowledge. Here, a case study is presented in which a controller is set up against a real-time model based on a hydraulic-press. The press model is designed following manufacturer specifications and it is embedded in a real-time simulator. This methodology ensures that the model achieves similar responses as the real machine that would be placed on the industry. A deterministic communication protocol is in charge of the bidirectional information transmission between the real-time model and the controller. This platform allows the engineer to test and verify the final control responses with exactly the same hardware that is going to be installed in the hydraulic-press, in other words, realize a virtual commissioning of the electro-hydraulic actuator. The Hardware in the Loop (HiL) platform validates in laboratory conditions and harmless for the machine the control algorithms designed, which allows embedding them afterwards in the industrial environment without further modifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deterministic%20communication%20protocol" title="deterministic communication protocol">deterministic communication protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=electro-hydraulic%20actuator" title=" electro-hydraulic actuator"> electro-hydraulic actuator</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware%20in%20the%20loop" title=" hardware in the loop"> hardware in the loop</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time" title=" real-time"> real-time</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20commissioning" title=" virtual commissioning"> virtual commissioning</a> </p> <a href="https://publications.waset.org/abstracts/97134/hardware-in-the-loop-platform-for-virtual-commissioning-case-study-of-a-hydraulic-press-model-simulated-in-real-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97134.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">142</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">1006</span> Mapping of Alteration Zones in Mineral Rich Belt of South-East Rajasthan Using Remote Sensing Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mrinmoy%20Dhara">Mrinmoy Dhara</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivek%20K.%20Sengar"> Vivek K.

Satellite images obtained by different sensors contain plenty of information related to the terrain. Digital image processing further helps in customized ways for the prospecting of minerals. In this study, an attempt has been made to map the hydrothermally altered zones using multispectral and hyperspectral datasets of South East Rajasthan. Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) and Hyperion (Level1R) dataset have been processed to generate different Band Ratio Composites (BRCs). For this study, ASTER derived BRCs were generated to delineate the alteration zones, gossans, abundant clays and host rocks. ASTER and Hyperion images were further processed to extract mineral end members and classified mineral maps have been produced using Spectral Angle Mapper (SAM) method. Results were validated with the geological map of the area which shows positive agreement with the image processing outputs. Thus, this study concludes that the band ratios and image processing in combination play significant role in demarcation of alteration zones which may provide pathfinders for mineral prospecting
