However, it is difficult to find analytical solution of these complex non-linear equations. Hence, verification of the numerical model should be carried out against field data and numerical predictions. This paper presents the verification of developed finite element model applying for unsteady flow in the open channels. The results of a proposed model indicate a good matching with both Preissmann scheme and HEC-RAS model for a river reach of 29 km at both sites (15 km from upstream and at downstream end) for discharge hydrographs. It also has an agreeable comparison with the Preissemann scheme for the flow depth (stage) hydrographs. The proposed model has also been applying to forecast daily discharges at 400 km downstream from Sukkur barrage, which demonstrates accurate model predictions with observed daily discharges. Hence, this model may be utilized for predicting and issuing flood warnings about flood hazardous in advance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=Preissmann%20scheme" title=" Preissmann scheme"> Preissmann scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=HEC-RAS" title=" HEC-RAS"> HEC-RAS</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20forecasting" title=" flood forecasting"> flood forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=Indus%20river" title=" Indus river"> Indus river</a> </p> <a href="https://publications.waset.org/abstracts/2616/verification-and-application-of-finite-element-model-developed-for-flood-routing-in-rivers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2616.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">504</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">2710</span> Intelligent Tutor Using Adaptive Learning to Partial Discharges with Virtual Reality Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hern%C3%A1ndez%20Yasmi%CC%81n">Hernández Yasmín</a>, <a href="https://publications.waset.org/abstracts/search?q=Ochoa%20Alberto"> Ochoa Alberto</a>, <a href="https://publications.waset.org/abstracts/search?q=Hurtado%20Diego"> Hurtado Diego</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is developing an intelligent tutoring system for electrical operators training with virtual reality systems at the laboratory center of partials discharges LAPEM.

We explain here the HBM standard in detail together with the typical failure modes associated with electrostatic discharges. In addition, a prototype of electrostatic charge generator has been designed, fabricated, and verified to stress electronic devices, which features a compact high voltage source. This prototype is inexpensive and enables one to do a battery of pre-compliance tests aimed at detecting unexpected weaknesses to static discharges at the component level. Some tests with different devices were performed to illustrate the behavior of the proposed generator. A set of discharges was applied according to the HBM standard to commercially available bipolar transistors, complementary metal-oxide-semiconductor transistors and light emitting diodes. It is observed that high current and voltage ratings in electronic devices not necessarily provide a guarantee that the device will withstand high levels of electrostatic discharges. We have also compared the result obtained by performing the sensitivity tests based on HBM with a real discharge generated by a human. For this purpose, the charge accumulated in the person is monitored, and a direct discharge against the devices is generated by touching them. Every test has been performed under controlled relative humidity conditions. It is believed that this paper can be of interest for research teams involved in the development of electronic and optoelectronic devices which need to verify the reliability of their devices in terms of robustness to electrostatic discharges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20body%20model" title="human body model">human body model</a>, <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20discharge" title=" electrostatic discharge"> electrostatic discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20tests" title=" sensitivity tests"> sensitivity tests</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20charge%20monitoring" title=" static charge monitoring"> static charge monitoring</a> </p> <a href="https://publications.waset.org/abstracts/107659/electronic-device-robustness-against-electrostatic-discharges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107659.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">149</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">2708</span> Audit on the Use of T-MACS Decision Aid for Patients Presenting to ED with Chest Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saurav%20Dhawan">Saurav Dhawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanchit%20Bansal"> Sanchit Bansal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background T-MACS is a computer-based decision aid that ‘rules in’ and ‘rules out’ ACS using a combination of the presence or absence of six clinical features with only one biomarker measured on arrival: hs-cTnT. T-MACS had 99.3% negative predictive value and 98.7% sensitivity for ACS, ‘ruling out’ ACS in 40% of patients while ‘ruling in’ 5% at the highest risk. We aim at benchmarking the use of T-MACS which could help to conserve healthcare resources, facilitate early discharges, and ensure safe practice. Methodology Randomized retrospective data collection (n=300) was done from ED electronic records across 3 hospital sites within MFT over a period of 2 months. Data was analysed and compared by percentage for the usage of T-MACS, number of admissions/discharges, and in days for length of stay in hospital. Results MRI A&E had the maximum compliance with the use of T-MACS in the trust at 66%, with minimum admissions (44%) and an average length of stay of 1.825 days. NMG A&E had an extremely low compliance rate (8 %), with 75% admission and 3.387 days as the average length of stay. WYT A&E had no TMACS recorded, with a maximum of 79% admissions and the longest average length of stay at 5.07 days. Conclusion All three hospital sites had a RAG rating of ‘RED’ as per the compliance levels. The assurance level was calculated as ‘Very Limited’ across all sites. There was a positive correlation observed between compliance with TMACS and direct discharges from ED, thereby reducing the average length of stay for patients in the hospital. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ACS" title="ACS">ACS</a>, <a href="https://publications.waset.org/abstracts/search?q=discharges" title=" discharges"> discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=ED" title=" ED"> ED</a>, <a href="https://publications.waset.org/abstracts/search?q=T-MACS" title=" T-MACS"> T-MACS</a> </p> <a href="https://publications.waset.org/abstracts/183275/audit-on-the-use-of-t-macs-decision-aid-for-patients-presenting-to-ed-with-chest-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183275.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">58</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">2707</span> Simulation and Performance Evaluation of Transmission Lines with Shield Wire Segmentation against Atmospheric Discharges Using ATPDraw</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcio%20S.%20da%20Silva">Marcio S. da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Mauricio%20de%20B.%20Bezerra"> Jose Mauricio de B.

As a goal of this work, it was established to make complete modeling of a transmission line in the ATPDraw program with shield wire grounded in all the towers and in some towers. The methodology used to make the proposed evaluation was to choose an actual transmission line that served as a case study. From the choice of transmission line and verification of all its topology and materials, complete modeling of the line using the ATPDraw software was performed. Then several atmospheric discharges were simulated by striking the grounded shield wires in each tower. These simulations served to identify the behavior of the existing line against atmospheric discharges. After this first analysis, the same line was reconsidered with shield wire segmentation. The shielding wire segmentation technique aims to reduce induced losses in shield wires and is adopted in some transmission lines in Brazil. With the same conditions of atmospheric discharge the transmission line, this time with shield wire segmentation was again evaluated. The results obtained showed that it is possible to obtain similar performances against atmospheric discharges between a shield wired line in multiple towers and the same line with shield wire segmentation if some precautions are adopted as verification of the ground resistance of the wire segmented shield, adequacy of the maximum length of the segmented gap, evaluation of the separation length of the electrodes of the insulator spark, among others. As a conclusion, it is verified that since the correct assessment and adopted the correct criteria of adjustment a transmission line with shielded wire segmentation can perform very similar to the traditional use with multiple earths. This solution contributes in a very important way to the reduction of energy losses in transmission lines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20discharges" title="atmospheric discharges">atmospheric discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=ATPDraw" title=" ATPDraw"> ATPDraw</a>, <a href="https://publications.waset.org/abstracts/search?q=shield%20wire" title=" shield wire"> shield wire</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20lines" title=" transmission lines"> transmission lines</a> </p> <a href="https://publications.waset.org/abstracts/103131/simulation-and-performance-evaluation-of-transmission-lines-with-shield-wire-segmentation-against-atmospheric-discharges-using-atpdraw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103131.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2706</span> Joint Modeling of Bottle Use, Daily Milk Intake from Bottles, and Daily Energy Intake in Toddlers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yungtai%20Lo">Yungtai Lo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current study follows an educational intervention on bottle-weaning to simultaneously evaluate the effect of the bottle-weaning intervention on reducing bottle use, daily milk intake from bottles, and daily energy intake in toddlers aged 11 to 13 months. A shared parameter model and a random effects model are used to jointly model bottle use, daily milk intake from bottles, and daily energy intake. We show in the two joint models that the bottle-weaning intervention promotes bottleweaning, and reduces daily milk intake from bottles in toddlers not off bottles and daily energy intake. We also show that the odds of drinking from a bottle were positively associated with the amount of milk intake from bottles and increased daily milk intake from bottles was associated with increased daily energy intake. The effect of bottle use on daily energy intake is through its effect on increasing daily milk intake from bottles that in turn increases daily energy intake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two-part%20model" title="two-part model">two-part model</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-continuous%20variable" title=" semi-continuous variable"> semi-continuous variable</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20model" title=" joint model"> joint model</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20regression" title=" gamma regression"> gamma regression</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20parameter%20model" title=" shared parameter model"> shared parameter model</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20effects%20model" title=" random effects model"> random effects model</a> </p> <a href="https://publications.waset.org/abstracts/46749/joint-modeling-of-bottle-use-daily-milk-intake-from-bottles-and-daily-energy-intake-in-toddlers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46749.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">287</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">2705</span> An Approximation of Daily Rainfall by Using a Pixel Value Data Approach </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarisa%20Pinkham">Sarisa Pinkham</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanyarat%20Bussaban"> Kanyarat Bussaban</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research aims to approximate the amount of daily rainfall by using a pixel value data approach.

In 50% of the discharges, the soft X-ray is seen to be emitted in short multiple pulses corresponding to different compression, whereas it is a single pulse for hard X-rays corresponding to only the first strong compression. It should be stated that multiple compressions dominantly occur at low pressures and high pressures are mostly in the single compression regime. In 43% of the discharges, at all pressures except for optimum pressure, the first period is characterized by two or more sharp peaks.The X–ray signal intensity during the second and subsequent compressions is much smaller than the first compression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasma%20focus%20device" title="plasma focus device">plasma focus device</a>, <a href="https://publications.waset.org/abstracts/search?q=SXR" title=" SXR"> SXR</a>, <a href="https://publications.waset.org/abstracts/search?q=HXR" title=" HXR"> HXR</a>, <a href="https://publications.waset.org/abstracts/search?q=Pin-diode" title=" Pin-diode"> Pin-diode</a>, <a href="https://publications.waset.org/abstracts/search?q=argon%20plasma" title=" argon plasma"> argon plasma</a> </p> <a href="https://publications.waset.org/abstracts/26796/comprehensive-study-of-x-ray-emission-by-apf-plasma-focus-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26796.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">408</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">2703</span> Insulation Properties of Rod-Plane Electrode Covered with ATH/SIR Nano-Composite in Dry-Air</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae-Yong%20Sim">Jae-Yong Sim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Hun%20Kwon"> Jung-Hun Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Sung%20Park"> Ji-Sung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kee-Joe%20Lim"> Kee-Joe Lim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the latest trends for insulation systems to improve the insulation performance is the use of eco-friendly hybrid insulation using compressed dry-air. Despite the excellent insulation performance of sulphurhexafluoride (SF6) gas, its use has been restricted due to the problems with significant global warming potential (GWP). Accordingly, lightning impulse performance of the hybrid insulation system covered with an aluminum trihydrate/silicone rubber (ATH/SIR) nanocomposite was examined in air at atmospheric pressure and in compressed air at pressures between 0.2 and 0.6 MPa. In the experiments, the most common breakdown path took place along the surface of the covered rod. The insulation reliability after several discharges should be guaranteed in hybrid insulation.

Therefore, nanoscale ATH can be used as a reinforcement of covered dielectrics to inhibit carbonization on the surface of a covered rod.

In daily stand-ups, team members gather to coordinate and align their efforts, typically for a predefined period of no more than 15 minutes. The primary purpose is to ask and answer the following three questions: What was accomplished yesterday? What will be done today? What obstacles are impeding my progress? Daily stand-ups aim to enhance communication, mutual understanding, and support within the team, as well as promote collective learning from mistakes through daily synchronization and transparency. The use of daily stand-ups is intended to positively influence psychological safety within teams, which is the belief that it is safe to show oneself and take personal risks. Two studies will be presented, which explore the relationships between daily stand-ups, psychological safety, and psychological well-being. In a first study, based on survey results (n = 318), we demonstrated that daily stand-ups have a positive indirect effect on job satisfaction and a negative indirect effect on turnover intention through their impact on psychological safety. In a second study, we investigate, using an experimental design, how the use of daily stand-ups in teams enhances psychological safety and well-being compared to a control group that does not use daily stand-ups. Psychological safety is considered one of the most crucial cultural factors for a sustainable, agile organization. Agile approaches, such as daily stand-ups, are a critical part of the evolving work environment and offer a proactive means to shape and foster psychological safety within teams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=occupational%20wellbeing" title="occupational wellbeing">occupational wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=agile%20work%20practices" title=" agile work practices"> agile work practices</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20safety" title=" psychological safety"> psychological safety</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20stand-ups" title=" daily stand-ups"> daily stand-ups</a> </p> <a href="https://publications.waset.org/abstracts/175856/daily-stand-up-meetings-relationships-with-psychological-safety-and-well-being-in-teams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175856.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">66</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">2701</span> Conservation and Development of Rural Everyday Landscapes in the Context of Modernization and Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xie%20Weifan">Xie Weifan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Zhongde"> Wang Zhongde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Everyday landscape in the countryside has long played an important role as a cultural representation of the countryside and a link between the countryside and social relations. In the transformation of modernization, the daily landscape in the countryside needs to change with the transformation of daily life in countryside therefore, interpreting the daily landscape in the countryside and understanding the basic characteristics and value perception of the daily landscape from the villagers' perspective can help to understand the daily landscape in the countryside and its conservation and development. Taking Lizi Village in Qianjiang District, Chongqing Municipality, China, as a case study, we collected important daily landscapes in villagers' perceptions through in-depth interviews, categorized them into personal living space, public affairs space, and public activity space, and analyzed the characteristics of the spatial distribution of daily landscapes. The perceptual characteristics of the villagers' perceptions are analyzed and divided into four major types, namely, physical environment perception, atmosphere and culture perception, emotional feelings, and behavioral preferences, and their perceptual characteristics are analyzed respectively to understand the important characteristics of the villagers' perceptions of the daily landscapes. Finally, it is proposed that the protection and development of daily landscape in villages need to improve the mechanism of discovering and evaluating daily landscape, encourage residents to participate in the construction of daily landscape, protect the high-value daily landscape, and promote the innovative development of daily landscape. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rural%20landscape" title="rural landscape">rural landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=everyday%20landscape" title=" everyday landscape"> everyday landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20perception" title=" landscape perception"> landscape perception</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation%20and%20development" title=" conservation and development"> conservation and development</a> </p> <a href="https://publications.waset.org/abstracts/191097/conservation-and-development-of-rural-everyday-landscapes-in-the-context-of-modernization-and-transformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191097.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">25</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">2700</span> New Findings on the Plasma Electrolytic Oxidation (PEO) of Aluminium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Martin">J.

Belmonte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The plasma electrolytic oxidation (PEO) is a particular electrochemical process to produce protective oxide ceramic coatings on light-weight metals (Al, Mg, Ti). When applied to aluminum alloys, the resulting PEO coating exhibit improved wear and corrosion resistance because thick, hard, compact and adherent crystalline alumina layers can be achieved. Several investigations have been carried out to improve the efficiency of the PEO process and one particular way consists in tuning the suitable electrical regime. Despite the considerable interest in this process, there is still no clear understanding of the underlying discharge mechanisms that make possible metal oxidation up to hundreds of µm through the ceramic layer. A key parameter that governs the PEO process is the numerous short-lived micro-discharges (micro-plasma in liquid) that occur continuously over the processed surface when the high applied voltage exceeds the critical dielectric breakdown value of the growing ceramic layer. By using a bipolar pulsed current to supply the electrodes, we previously observed that micro-discharges are delayed with respect to the rising edge of the anodic current. Nevertheless, explanation of the origin of such phenomena is still not clear and needs more systematic investigations. The aim of the present communication is to identify the relationship that exists between this delay and the mechanisms responsible of the oxide growth. For this purpose, the delay of micro-discharges ignition is investigated as the function of various electrical parameters such as the current density (J), the current pulse frequency (F) and the anodic to cathodic charge quantity ratio (R = Qp/Qn) delivered to the electrodes. The PEO process was conducted on Al2214 aluminum alloy substrates in a solution containing potassium hydroxide [KOH] and sodium silicate diluted in deionized water. The light emitted from micro-discharges was detected by a photomultiplier and the micro-discharge parameters (number, size, life-time) were measured during the process by means of ultra-fast video imaging (125 kfr./s). SEM observations and roughness measurements were performed to characterize the morphology of the elaborated oxide coatings while XRD was carried out to evaluate the amount of corundum -Al203 phase. Results show that whatever the applied current waveform, the delay of micro-discharge appearance increases as the process goes on. Moreover, the delay is shorter when the current density J (A/dm2), the current pulse frequency F (Hz) and the ratio of charge quantity R are high. It also appears that shorter delays are associated to stronger micro-discharges (localized, long and large micro-discharges) which have a detrimental effect on the elaborated oxide layers (thin and porous). On the basis of the results, a model for the growth of the PEO oxide layers will be presented and discussed. Experimental results support that a mechanism of electrical charge accumulation at the oxide surface / electrolyte interface takes place until the dielectric breakdown occurs and thus until micro-discharges appear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium" title="aluminium">aluminium</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-discharges" title=" micro-discharges"> micro-discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation%20mechanisms" title=" oxidation mechanisms"> oxidation mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20electrolytic%20oxidation" title=" plasma electrolytic oxidation "> plasma electrolytic oxidation </a> </p> <a href="https://publications.waset.org/abstracts/37937/new-findings-on-the-plasma-electrolytic-oxidation-peo-of-aluminium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37937.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2699</span> Oxygenation in Turbulent Flows over Block Ramps</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thendiyath%20Roshni">Thendiyath Roshni</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Pagliara"> Stefano Pagliara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Block ramps (BR) or rock chutes are eco-friendly natural river restoration structures. BR are made of ramp of rocks and flows over BR develop turbulence and helps in the entrainment of ambient air. These act as natural aerators in river flow and therefore leads to oxygenation of water. As many of the hydraulic structures in rivers, hinders the natural path for aquatic habitat. However, flows over BR ascertains a natural rocky flow and ensures safe and natural movement for aquatic habitat. Hence, BR is considered as a better alternative for drop structures. As water quality is concerned, turbulent and aerated flows over BR or macro-roughness conditions improves aeration and thereby oxygenation. Hence, the objective of this paper is to study the oxygenation in the turbulent flows over BR. Experimental data were taken for a slope (S) of 27.5% for three discharges (Q = 9, 15 and 21 lps) conditions. Air concentration were measured with the help of air concentration probe for three different discharges in the uniform flow region. Oxygen concentration is deduced from the air concentration as ambient air is entrained in the flows over BR. Air concentration profiles and oxygen profiles are plotted in the uniform flow region for three discharges and found that air concentration and oxygen concentration does not show any remarkable variation in properties in the longitudinal profile in uniform flow region. An empirical relation is developed for finding the average oxygen concentration (Oₘ) for S = 27.5% in the uniform flow region for 9 < Q < 21 lps. The results show that as the discharge increases over BR, there is a reduction of oxygen concentration in the uniform flow region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeration" title="aeration">aeration</a>, <a href="https://publications.waset.org/abstracts/search?q=block%20ramps" title=" block ramps"> block ramps</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygenation" title=" oxygenation"> oxygenation</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flows" title=" turbulent flows"> turbulent flows</a> </p> <a href="https://publications.waset.org/abstracts/98618/oxygenation-in-turbulent-flows-over-block-ramps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98618.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">174</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">2698</span> Application of an Analytical Model to Obtain Daily Flow Duration Curves for Different Hydrological Regimes in Switzerland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Clara%20Santos">Ana Clara Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Manuela%20Portela"> Maria Manuela Portela</a>, <a href="https://publications.waset.org/abstracts/search?q=Bettina%20Schaefli"> Bettina Schaefli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work assesses the performance of an analytical model framework to generate daily flow duration curves, FDCs, based on climatic characteristics of the catchments and on their streamflow recession coefficients. According to the analytical model framework, precipitation is considered to be a stochastic process, modeled as a marked Poisson process, and recession is considered to be deterministic, with parameters that can be computed based on different models. The analytical model framework was tested for three case studies with different hydrological regimes located in Switzerland: pluvial, snow-dominated and glacier. For that purpose, five time intervals were analyzed (the four meteorological seasons and the civil year) and two developments of the model were tested: one considering a linear recession model and the other adopting a nonlinear recession model. Those developments were combined with recession coefficients obtained from two different approaches: forward and inverse estimation. The performance of the analytical framework when considering forward parameter estimation is poor in comparison with the inverse estimation for both, linear and nonlinear models. For the pluvial catchment, the inverse estimation shows exceptional good results, especially for the nonlinear model, clearing suggesting that the model has the ability to describe FDCs. For the snow-dominated and glacier catchments the seasonal results are better than the annual ones suggesting that the model can describe streamflows in those conditions and that future efforts should focus on improving and combining seasonal curves instead of considering single annual ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20streamflow%20distribution" title="analytical streamflow distribution">analytical streamflow distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20process" title=" stochastic process"> stochastic process</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20and%20non-linear%20recession" title=" linear and non-linear recession"> linear and non-linear recession</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrological%20modelling" title=" hydrological modelling"> hydrological modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20discharges" title=" daily discharges"> daily discharges</a> </p> <a href="https://publications.waset.org/abstracts/98484/application-of-an-analytical-model-to-obtain-daily-flow-duration-curves-for-different-hydrological-regimes-in-switzerland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98484.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">162</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">2697</span> Technico-Economical Study of a Rapeseed Based Biorefinery Using High Voltage Electrical Discharges and Ultrasounds as Pretreatment Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Brahim">Marwa Brahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Brosse"> Nicolas Brosse</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Boussetta"> Nadia Boussetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Grimi"> Nabil Grimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Vorobiev"> Eugene Vorobiev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rapeseed plant is an established product in France which is mainly dedicated to oil production. However, the economic potential of residues from this industry (rapeseed hulls, rapeseed cake, rapeseed straw etc.), has not been fully exploited. Currently, only low-grade applications are found in the market. As a consequence, it was deemed of interest to develop a technological platform aiming to convert rapeseed residues into value- added products. Specifically, a focus is given on the conversion of rapeseed straw into valuable molecules (e.g. lignin, glucose). Existing pretreatment technologies have many drawbacks mainly the production of sugar degradation products that limit the effectiveness of saccharification and fermentation steps in the overall scheme of the lignocellulosic biorefinery. In addition, the viability of fractionation strategies is a challenge in an environmental context increasingly standardized. Hence, the need to find cleaner alternatives with comparable efficiency by implementing physical phenomena that could destabilize the structural integrity of biomass without necessarily using chemical solvents. To meet environmental standards increasingly stringent, the present work aims to study the new pretreatment strategies involving lower consumption of chemicals with an attenuation of the severity of the treatment. These strategies consist on coupling physical treatments either high voltage electrical discharges or ultrasounds to conventional chemical pretreatments (soda and organosolv). Ultrasounds treatment is based on the cavitation phenomenon, and high voltage electrical discharges cause an electrical breakdown accompanied by many secondary phenomena. The choice of process was based on a technological feasibility study taking into account the economic profitability of the whole chain after products valorization. Priority was given to sugars valorization into bioethanol and lignin sale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20voltage%20electrical%20discharges" title="high voltage electrical discharges">high voltage electrical discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=organosolv" title=" organosolv"> organosolv</a>, <a href="https://publications.waset.org/abstracts/search?q=pretreatment%20strategies" title=" pretreatment strategies"> pretreatment strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=rapeseed%20straw" title=" rapeseed straw"> rapeseed straw</a>, <a href="https://publications.waset.org/abstracts/search?q=soda" title=" soda"> soda</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasounds" title=" ultrasounds"> ultrasounds</a> </p> <a href="https://publications.waset.org/abstracts/58493/technico-economical-study-of-a-rapeseed-based-biorefinery-using-high-voltage-electrical-discharges-and-ultrasounds-as-pretreatment-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58493.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">363</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">2696</span> Musical Tesla Coil with Faraday Box Controlled by a GNU Radio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jairo%20Vega">Jairo Vega</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabian%20Chamba"> Fabian Chamba</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordy%20Urgiles"> Jordy Urgiles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the implementation of a Matlabcontrolled Musical Tesla Coil and external audio signals was presented.

These ever-increasing data demands require not only more and more capacity of the transmission channels but also results in resource over-provision to meet the resilience requirements, thus the unavoidable waste because of the data fluctuations throughout the day. In addition, the high energy consumption (EC) and carbon discharges from these data transmissions posing serious issues to the environment we live in. Therefore, to overcome the issues of intensive EC and carbon emissions (CE) of massive data dissemination in Smart Cities, we propose an energy efficient and carbon reduction approach by utilizing the daily mobility of the existing vehicles as an alternative communications channel to accommodate the data dissemination in smart cities. To illustrate the effectiveness and efficiency of our approach, we take the Auckland City in New Zealand as an example, assuming massive data generated by various sources geographically scattered throughout the Auckland region to the control centres located in city centre. The numerical results show that our proposed approach can provide up to 5 times lower delay as transferring the large volume of data by utilizing the existing daily vehicles’ mobility than the conventional transmission network. Moreover, our proposed approach offers about 30% less EC and CE than that of conventional network transmission approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title="smart city">smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=delay%20tolerant%20network" title=" delay tolerant network"> delay tolerant network</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure%20offloading" title=" infrastructure offloading"> infrastructure offloading</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunistic%20network" title=" opportunistic network"> opportunistic network</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicular%20mobility" title=" vehicular mobility"> vehicular mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20emission" title=" carbon emission"> carbon emission</a> </p> <a href="https://publications.waset.org/abstracts/166727/energy-efficient-massive-data-dissemination-through-vehicle-mobility-in-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166727.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">2693</span> Behavior of Printing Inks on Historical Documents Subjected to Cold RF Plasma Discharges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dorina%20Rusu">Dorina Rusu</a>, <a href="https://publications.waset.org/abstracts/search?q=Emil%20Ghiocel%20Ioanid"> Emil Ghiocel Ioanid</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Ursescu"> Marta Ursescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Maria%20Vlad"> Ana Maria Vlad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mihaela%20Popescu"> Mihaela Popescu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decades the cold plasma discharges made the subject of numerous studies concerning the applications in the cultural heritage field, especially concentrated on ecological and non-invasive aspect of these conservation procedures. The conservation treatment using cold plasma is based, on the one hand, on the well-known property of plasma discharges to inactivate the contaminant biological species and, on the other hand, on the surface cleaning effect. Moreover the plasma discharge produces the functionalization of the treated surface, allowing subsequent deposition of protective layers. The paper presents the behavior of printing inks on historical documents treated in cold RF plasma. Two types of printing inks were studied, namely red and black ink, used on a religious book published in 19 century. SEM-EDX analysis results in the identification of the two inks as carbon black ink (C presence in the EDX spectrum) and cinnabar based red ink (Hg and S lines in the spectrum), result confirmed by XRF analysis. The experiments have been performed on paper samples written with laboratory- made inks, of similar composition with the inks identified on historical documents. The samples were subjected to RF plasma discharge, operating in nitrogen gaseous medium, at 1.2 MHz frequency and low-pressure (0.5 mbar), performed in a self-designed equipment for the application of conservation treatments on naturally aged paper supports. The impact of plasma discharge on the inks has been evaluated by SEM, XRD and color analysis. The color analysis revealed a slight discoloration of cinnabar ink on the historical document. SEM and XRD analyses have been carried out in an attempt to elucidate the process responsable for color modification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RF%20plasma" title="RF plasma">RF plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=printing%20inks" title=" printing inks"> printing inks</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20documents" title=" historical documents"> historical documents</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20cleaning%20effect" title=" surface cleaning effect"> surface cleaning effect</a> </p> <a href="https://publications.waset.org/abstracts/27316/behavior-of-printing-inks-on-historical-documents-subjected-to-cold-rf-plasma-discharges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27316.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">439</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">2692</span> Chaotic Response of Electrical Insulation System with Gaseous Dielectric under High AC and DC Voltages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arijit%20Basuray">Arijit Basuray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well known that if an electrical insulation system is stressed under high voltage then discharge may occur in various form and if the system is made of composite dielectric having interfaces of materials having different dielectric constant discharge may occur due to gross mismatch of dielectric constant causing intense local field in the interfaces. Here author has studied, firstly, behavior of discharges in gaseous dielectric circuit under AC and DC voltages. A gaseous dielectric circuit is made such that a pair of electrode of typical geometry is used to make the discharges occur under application of AC and DC voltages. Later on, composite insulation system with air gap is also studied. Discharge response of the dielectric circuit is measured across a typically designed impedance.

Rapidly increasing water requests can be supported provided that further uses of a river course are not totally compromised, and environmental features are protected as well. Strictly speaking, a water concession can be considered a continuous drawing from the source and causes a mean annual streamflow reduction. Therefore, deciding if a water concession is appropriate or inappropriate seems to be easily solved by comparing the generic demand to the mean annual streamflow value at disposal. Still, the immediate shortcoming for such a comparison is that streamflow data are information available only for few catchments and, most often, limited to specific sites. Subsequently, comparing the generic water demand to mean daily discharge is indeed far from being completely satisfactory since the mean daily streamflow is greater than the water withdrawal for a long period of a year. Consequently, such a comparison appears to be of little significance in order to preserve the quality and the quantity of the river. In order to overcome such a limit, this study aims to complete the information provided by flow duration curves introducing a link between Flow Duration Curves (FDCs) and recession curves and aims to show the chronological sequence of flows with a particular focus on low flow data. The analysis is carried out on 25 catchments located in North-Eastern Italy for which daily data are provided. The results identify groups of catchments as hydrologically homogeneous, having the lower part of the FDCs (corresponding streamflow interval is streamflow Q between 300 and 335, namely: Q(300), Q(335)) smoothly reproduced by a common recession curve. In conclusion, the results are useful to provide more reliable answers to water request, especially for those catchments which show similar hydrological response and can be used for a focused regionalization approach on low flow data. A mathematical link between streamflow duration curves and recession curves is herein provided, thus furnishing streamflow duration curves information upon a temporal sequence of data. In such a way, by introducing assumptions on recession curves, the chronological sequence upon low flow data can also be attributed to FDCs, which are known to lack this information by nature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronological%20sequence%20of%20discharges" title="chronological sequence of discharges">chronological sequence of discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=recession%20curves" title=" recession curves"> recession curves</a>, <a href="https://publications.waset.org/abstracts/search?q=streamflow%20duration%20curves" title=" streamflow duration curves"> streamflow duration curves</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20concession" title=" water concession"> water concession</a> </p> <a href="https://publications.waset.org/abstracts/131516/flow-duration-curves-and-recession-curves-connection-through-a-mathematical-link" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131516.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">186</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">2690</span> Deliberation of Daily Evapotranspiration and Evaporative Fraction Based on Remote Sensing Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Bahrawi">J.

Traditional techniques of calculating daily evapotranspiration based on field measurements are valid only for local scales. Earth observation satellite sensors are thus used to overcome difficulties in obtaining daily evapotranspiration measurements on regional scale. The Surface Energy Balance System (SEBS) model was adopted to estimate daily evapotranspiration and relative evaporation along with other land surface energy fluxes. The model requires agro-climatic data that improve the model outputs. Advance Along Track Scanning Radiometer (AATSR) and Medium Spectral Resolution Imaging Spectrometer (MERIS) imageries were used to estimate the daily evapotranspiration and relative evaporation over the entire Nile Delta region in Egypt supported by meteorological data collected from six different weather stations located within the study area. Daily evapotranspiration maps derived from SEBS model show a strong agreement with actual ground-truth data taken from 92 points uniformly distributed all over the study area. Moreover, daily evapotranspiration and relative evaporation are strongly correlated. The reliable estimation of daily evapotranspiration supports the decision makers to review the current land use practices in terms of water management, while enabling them to propose proper land use changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=daily%20evapotranspiration" title="daily evapotranspiration">daily evapotranspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20evaporation" title=" relative evaporation"> relative evaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=SEBS" title=" SEBS"> SEBS</a>, <a href="https://publications.waset.org/abstracts/search?q=AATSR" title=" AATSR"> AATSR</a>, <a href="https://publications.waset.org/abstracts/search?q=MERIS" title=" MERIS"> MERIS</a>, <a href="https://publications.waset.org/abstracts/search?q=Nile%20Delta" title=" Nile Delta"> Nile Delta</a> </p> <a href="https://publications.waset.org/abstracts/26889/deliberation-of-daily-evapotranspiration-and-evaporative-fraction-based-on-remote-sensing-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26889.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">259</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2689</span> The Impact of Land Cover Change on Stream Discharges and Water Resources in Luvuvhu River Catchment, Vhembe District, Limpopo Province, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20M.%20Kundu">P.

The generation of runoff is triggered by the rainfall intensity and soil moisture status. In this study, remote sensing and GIS techniques were used to analyze the hydrologic response to land cover changes. Runoff was calculated as a product of the net precipitation and a curve number coefficient. It was then routed using the Muskingum-Cunge method using a diffusive wave transfer model that enabled the calculation of response functions between start and end point. Flood frequency analysis was determined using theoretical probability distributions. Spatial data on land cover was obtained from multi-temporal Landsat images while data on rainfall, soil type, runoff and stream discharges was obtained by direct measurements in the field and from the Department of Water. A digital elevation model was generated from contour maps available at http://www.ngi.gov.za. The results showed that land cover changes had impacted negatively to the hydrology of the catchment. Peak discharges in the whole catchment were noted to have increased by at least 17% over the period while flood volumes were noted to have increased by at least 11% over the same period. The flood time to peak indicated a decreasing trend, in the range of 0.5 to 1 hour within the years. The synergism between remotely sensed digital data and GIS for land surface analysis and modeling was realized, and it was therefore concluded that hydrologic modeling has potential for determining the influence of changes in land cover on the hydrologic response of the catchment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catchment" title="catchment">catchment</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20elevation%20model" title=" digital elevation model"> digital elevation model</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrological%20model" title=" hydrological model"> hydrological model</a>, <a href="https://publications.waset.org/abstracts/search?q=routing" title=" routing"> routing</a>, <a href="https://publications.waset.org/abstracts/search?q=runoff" title=" runoff"> runoff</a> </p> <a href="https://publications.waset.org/abstracts/23083/the-impact-of-land-cover-change-on-stream-discharges-and-water-resources-in-luvuvhu-river-catchment-vhembe-district-limpopo-province-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23083.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">566</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">2688</span> The Return of Daily Life — Improvement Experiments on Urban Village in the Post-Urban Village Era</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gan%20Lu">Gan Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Lei"> Xu Lei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This is an era when urban village is disappearing in China.

There is no agreement about the form the hydrometeors that could be the best for the lightning initiation from the thundercloud. Artificial charged water aerosol clouds of the positive or negative polarity could help investigate the possible influence of the hydrometeor form on the peculiarities and the probability of the lightning discharge initiation between the thundercloud and the ground. Artificial charged aerosol clouds that could create the electric field strength in the range of 5-6 kV/cm to 16-18 kV/cm have been used in experiments. The array of the model hydrometeors of the volume and plate form has been disposed near the bottom cloud boundary. It was established that the different kinds of the discharge could be initiated in the presence of the model hydrometeors array – from the cloud discharges up to the diffuse and channel discharges between the charged cloud and the ground. It was found that the form of the model hydrometeors could significantly influence the channel discharge initiation from the artificial charged aerosol cloud of the negative or positive polarity correspondingly. Analysis and generalization of the experimental results have shown that the maximal probability of the channel discharge initiation and propagation stimulation has been observed for the artificial charged cloud of the positive polarity when the arrays of the model hydrometeors of the cylinder revolution form have been used. At the same time, for the artificial charged clouds of the negative polarity, application of the model hydrometeor array of the plate rhombus form has provided the maximal probability of the channel discharge formation between the charged cloud and the ground. The established influence of the form of the model hydrometeors on the channel discharge initiation and from the artificial charged water aerosol cloud and its following successful propagation has been related with the different character of the positive and negative streamer and volume leader development on the model hydrometeors array being near the bottom boundary of the charged cloud. The received experimental results have shown the possibly important role of the form of the large hail particles precipitated in thundercloud on the discharge initiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20and%20channel%20discharges" title="cloud and channel discharges">cloud and channel discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrometeor%20form" title=" hydrometeor form"> hydrometeor form</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20initiation" title=" lightning initiation"> lightning initiation</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20and%20positive%20artificial%20charged%20aerosol%20cloud" title=" negative and positive artificial charged aerosol cloud"> negative and positive artificial charged aerosol cloud</a> </p> <a href="https://publications.waset.org/abstracts/67721/influence-of-model-hydrometeor-form-on-probability-of-discharge-initiation-from-artificial-charged-water-aerosol-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67721.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">316</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">2685</span> Increase Daily Production Rate of Methane Through Pasteurization Cow Dung</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Elbadawi%20Elshafea">Khalid Elbadawi Elshafea</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Hassan%20Onsa"> Mahmoud Hassan Onsa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the results of the experiments to measure the impact of pasteurization cows dung on important parameter of anaerobic digestion (retention time) and measure the effect in daily production rate of biogas, were used local materials in these experiments, two experiments were carried out in two bio-digesters (1 and 2) (18.0 L), volume of the mixture 16.0-litre and the mass of dry matter in the mixture 4.0 Kg of cow dung.

This study concluded that the use of system pasteurization cows dung speed up hydrolysis in anaerobic process, because heat to certain temperature in certain time lead to speed up chemical reactions (transfer Protein to Amino acids, Carbohydrate to Sugars and Fat to Long chain fatty acids), this lead to reduce the retention time an therefore increase the daily methane production rate with 212%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methane" title="methane">methane</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20dung" title=" cow dung"> cow dung</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20production" title=" daily production"> daily production</a>, <a href="https://publications.waset.org/abstracts/search?q=pasteurization" title=" pasteurization"> pasteurization</a>, <a href="https://publications.waset.org/abstracts/search?q=increase" title=" increase"> increase</a> </p> <a href="https://publications.waset.org/abstracts/46498/increase-daily-production-rate-of-methane-through-pasteurization-cow-dung" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46498.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">310</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">2684</span> Investigation of the Influencing Factors of Functional Communication Assessment for Adults with Aphasia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yun-Ching%20Tu">Yun-Ching Tu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Chun%20Chih"> Yu-Chun Chih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People with aphasia (PWA) may have communicative difficulties in their daily lives, but research on functional communication in aphasia is still limited in Taiwan. The aim of the study was to investigate the impact of aphasia-related factors on functional communication assessment. This study adopted a convenience sampling method. Thirty aphasic participants participated in the study. During the test, the examiner would ask questions that are encountered in daily life and record the participant‘s responses. Some questions would provide pictures to simulate situations in daily life. The results showed that the non-fluent aphasia group performed significantly worse than the fluent aphasia group. In addition, patients with severe aphasia performed significantly lower scores than patients with moderate aphasia and mild aphasia. However, group differences in the chronic stage and acute stage were not significant. In sum, since communication in daily life is diverse and language is still needed in the communication process, patients with aphasia who have better language ability may have relatively better functional communication. In contrast, the more severely impaired the language ability of a patient with aphasia is, the more functional communication will be affected, resulting in poor communication performance in daily life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult" title="adult">adult</a>, <a href="https://publications.waset.org/abstracts/search?q=aphasia" title=" aphasia"> aphasia</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20communication" title=" functional communication"> functional communication</a> </p> <a href="https://publications.waset.org/abstracts/177696/investigation-of-the-influencing-factors-of-functional-communication-assessment-for-adults-with-aphasia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177696.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">75</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">2683</span> Defect Identification in Partial Discharge Patterns of Gas Insulated Switchgear and Straight Cable Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chien-Kuo%20Chang">Chien-Kuo Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Hsiang%20Lin"> Yu-Hsiang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Yun%20Tang"> Yi-Yun Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Chiu%20Wu"> Min-Chiu Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the trend of technological advancement, the harm caused by power outages is substantial, mostly due to problems in the power grid. This highlights the necessity for further improvement in the reliability of the power system. In the power system, gas-insulated switches (GIS) and power cables play a crucial role. Long-term operation under high voltage can cause insulation materials in the equipment to crack, potentially leading to partial discharges. If these partial discharges (PD) can be analyzed, preventative maintenance and replacement of equipment can be carried out, there by improving the reliability of the power grid. This research will diagnose defects by identifying three different defects in GIS and three different defects in straight cable joints, for a total of six types of defects. The partial discharge data measured will be converted through phase analysis diagrams and pulse sequence analysis. Discharge features will be extracted using convolutional image processing, and three different deep learning models, CNN, ResNet18, and MobileNet, will be used for training and evaluation. Class Activation Mapping will be utilized to interpret the black-box problem of deep learning models, with each model achieving an accuracy rate of over 95%. Lastly, the overall model performance will be enhanced through an ensemble learning voting method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20discharge" title="partial discharge">partial discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=gas-insulated%20switches" title=" gas-insulated switches"> gas-insulated switches</a>, <a href="https://publications.waset.org/abstracts/search?q=straight%20cable%20joint" title=" straight cable joint"> straight cable joint</a>, <a href="https://publications.waset.org/abstracts/search?q=defect%20identification" title=" defect identification"> defect identification</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble%20learning" title=" ensemble learning"> ensemble learning</a> </p> <a href="https://publications.waset.org/abstracts/169443/defect-identification-in-partial-discharge-patterns-of-gas-insulated-switchgear-and-straight-cable-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169443.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2682</span> Experimental Parameters’ Effects on the Electrical Discharge Machining Performances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmae%20Tafraouti">Asmae Tafraouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasmina%20Layouni"> Yasmina Layouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascal%20Kleimann"> Pascal Kleimann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The growing market for Microsystems (MST) and Micro-Electromechanical Systems (MEMS) is driving the research for alternative manufacturing techniques to microelectronics-based technologies, which are generally expensive and time-consuming. Hot-embossing and micro-injection modeling of thermoplastics appear to be industrially viable processes. However, both require the use of master models, usually made in hard materials such as steel. These master models cannot be fabricated using standard microelectronics processes. Thus, other micromachining processes are used, such as laser machining or micro-electrical discharge machining (µEDM). In this work, µEDM has been used. The principle of µEDM is based on the use of a thin cylindrical micro-tool that erodes the workpiece surface. The two electrodes are immersed in a dielectric with a distance of a few micrometers (gap). When an electrical voltage is applied between the two electrodes, electrical discharges are generated, which cause material machining. In order to produce master models with high resolution and smooth surfaces, it is necessary to well control the discharge mechanism. However, several problems are encountered, such as a random electrical discharge process, the fluctuation of the discharge energy, the electrodes' polarity inversion, and the wear of the micro-tool. The effect of different parameters, such as the applied voltage, the working capacitor, the micro-tool diameter, and the initial gap, has been studied. This analysis helps to improve the machining performances, such as the workpiece surface condition and the lateral crater's gap. <p class="card-text"><strong>Keywords:</strong> <a
