Timely rehabilitation is crucial for improving patient outcomes and reducing healthcare costs, yet delays in rehabilitation, often due to challenges in discharge processes, can lead to adverse events and increased healthcare burdens. Aim: The study aimed to investigate two primary aspects related to hip fracture older adults patients: firstly, identifying subgroups more prone to delayed discharge for further rehabilitation; and secondly, exploring the consequences of this delay on short-term outcomes and the incidence of adverse events. Methods: Conducting a retrospective analysis, we examined the medical records of 474 patients aged 65 and older, hospitalized for hip fractures between 2018 and 2022 in a major hospital in the north-central region of Israel. All patients were eligible for further rehabilitation, including options for in-patient or home-based care. Results: Of the studied patients, 61.4% experienced delayed discharge, with an average waiting period of 3.5 days. Factors such as older age, prolonged hospital stay, and the need for in-patient rehabilitation were associated with a higher likelihood of delayed discharge. Those promptly discharged demonstrated lower rates of infections, falls, and mortality. Furthermore, delayed discharge to further rehabilitation correlated with elevated hospitalization costs. Notably, no significant differences were observed in re-hospitalization or repeat surgery rates. Conclusion: This study underscores the pressing need for efficient strategies to ensure timely rehabilitation, particularly for older adults. Implementing such strategies can optimize outcomes, mitigate adverse events, and contribute to a reduction in healthcare costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hip%20fracture%20rehabilitation" title="hip fracture rehabilitation">hip fracture rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=delayed%20discharge" title=" delayed discharge"> delayed discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=older%20adults" title=" older adults"> older adults</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20coordination" title=" healthcare coordination"> healthcare coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=adverse%20events" title=" adverse events"> adverse events</a> </p> <a href="https://publications.waset.org/abstracts/189292/optimizing-rehabilitation-transitions-delays-determinants-and-outcomes-in-hip-fracture-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189292.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">27</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">1278</span> Temporary Ureteric Catheterization after Ureteropyeloscopy: Experience from Regional Australia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jake%20Tempo">Jake Tempo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jack%20Crozier"> Jack Crozier</a>, <a href="https://publications.waset.org/abstracts/search?q=Huay%20Ann%20Chia"> Huay Ann Chia</a>, <a href="https://publications.waset.org/abstracts/search?q=Philip%20Tan"> Philip Tan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: A prospective study was performed to determine whether temporary ureteric catheterization should be eliminated as a prophylactic method for preventing ureteric obstruction after uncomplicated ureteropyeloscopic lithotripsy. Material and Methods: From 2010 to 2014, 227 patients underwent uncomplicated ureteroscopic and/or pyeloscopic lithotripsy. Three patient-groups based on postoperative drainage method were analysed: temporary uretericcatheter (TUC), -ureteric JJ stent, and no-stent groups. Exclusion criteria included urosepsis, ureteric injury, and non-surgical complications delaying hospital-discharge. Outcome measures included parenteral analgesic requirements, prolonged hospitalization ≥2 days due to postoperative-pain, and readmissions rate. Results: Delayed discharge was reported in 14.5%(9 of 62) patients in the TUC group compared to 3.4%(4 of 119) in theureteric JJ stent group and 8.7%(4 of 46) in the no-drainage-group (p=0.02). Odds ratio for delayed-discharge between catheter- versus-ureteric JJ stent is 4.9 (95% CI = 1.6-15.0; p < 0.01). Parenteral analgesic requirements in the TUC group (12.9%) was also significantly higher than theureteric JJ stent group (1.7%; p=0.003). Readmissions were negligible between groups. Conclusions: Patients with ureteric catheters after uncomplicated ureteroscopy have a prolonged hospital stay with increased pain and parenteral analgesic requirements. There is a 7.6-fold increased requirement for parenteral analgesia and a 4.2-fold increased risk of delayed-discharge compared to a patient with a ureteric JJ stent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ureteric%20catheter" title="ureteric catheter">ureteric catheter</a>, <a href="https://publications.waset.org/abstracts/search?q=ureteric%20stent" title=" ureteric stent"> ureteric stent</a>, <a href="https://publications.waset.org/abstracts/search?q=ureteroscopy" title=" ureteroscopy"> ureteroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=pyeloscopy" title=" pyeloscopy"> pyeloscopy</a> </p> <a href="https://publications.waset.org/abstracts/145169/temporary-ureteric-catheterization-after-ureteropyeloscopy-experience-from-regional-australia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145169.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">145</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">1277</span> Delayed Contralateral Prophylactic Mastectomy (CPM): Reasons and Rationale for Patients with Unilateral Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Soh">C.

Benson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction Reasons for requesting CPM include prevention of recurrence, peace of mind and moving on after breast cancer. Some women seek CPM as a delayed procedure but factors influencing this are poorly understood. Methods A retrospective analysis examined patients undergoing CPM as either an immediate or delayed procedure with or without breast reconstruction (BR) between January 2009 and December 2019. A cross-sectional survey based on validated questionnaires (5 point Likert scale) explored patients’ decision-making process in terms of timing of CPM and any BR. Results A total of 123 patients with unilateral breast cancer underwent CPM with 39 (32.5%) delayed procedures with or without BR. The response rate amongst patients receiving questionnaires (n=33) was 22/33 (66%). Within this delayed CPM cohort were three reconstructive scenarios 1) unilateral immediate BR with CPM (n=12); 2) delayed CPM with concomitant bilateral BR (n=22); 3) delayed bilateral BR after delayed CPM (n=3). Two patients had delayed CPM without BR. The most common reason for delayed CPM was to complete all cancer treatments (including radiotherapy) before surgery on the unaffected breast (score 2.91). The second reason was unavailability of genetic test results at the time of therapeutic mastectomy (score 2.64) whilst the third most cited reason was a subsequent change in family cancer history. Conclusion Factors for delayed CPM are patient-driven with few women spontaneously changing their mind having initially decided against immediate CPM for reasons also including surgical duration. CPM should be offered as a potentially delayed option with informed discussion of risks and benefits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Breast%20Cancer" title="Breast Cancer">Breast Cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=CPM" title="CPM">CPM</a>, <a href="https://publications.waset.org/abstracts/search?q=Prophylactic" title="Prophylactic">Prophylactic</a>, <a href="https://publications.waset.org/abstracts/search?q=Rationale" title="Rationale">Rationale</a> </p> <a href="https://publications.waset.org/abstracts/147785/delayed-contralateral-prophylactic-mastectomy-cpm-reasons-and-rationale-for-patients-with-unilateral-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147785.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">112</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">1276</span> Detecting Trends in Annual Discharge and Precipitation in the Chott Melghir Basin in Southeastern Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20T.%20Bouziane">M.

These data were analyzed with the aid of Kendall test trend and regression analysis. The results indicate that the major variations in all catchments discharge in Chott Melghir correspond well to the precipitation. Changes in total annual discharge of Chott Melghir were lower than changes in annual precipitation. Annual precipitation decreased by 66 percent and annual discharge decreased by 4 percent. No significant trend is detected for annual discharge and precipitation at major catchments up to 95% confidence level. The decreasing trend in Chott Melghir discharge is mainly attributed to the decrease of precipitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trends" title="trends">trends</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation" title=" precipitation"> precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=discharge" title=" discharge"> discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=Kendall%20test" title=" Kendall test"> Kendall test</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20analysis" title=" regression analysis"> regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Chott%20Melghir%20catchments" title=" Chott Melghir catchments"> Chott Melghir catchments</a> </p> <a href="https://publications.waset.org/abstracts/12752/detecting-trends-in-annual-discharge-and-precipitation-in-the-chott-melghir-basin-in-southeastern-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12752.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">304</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">1275</span> Optimal Tuning of a Fuzzy Immune PID Parameters to Control a Delayed System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Gherbi">S.

However, the hydraulic behavior of this type of weir is complex and difficult to predict accurately. An accurate flow prediction over a weir mainly depends on the proper estimation of discharge coefficient. In this study, the Genetic Expression Programming (GEP) approach was used for predicting trapezoidal and rectangular sharp-crested side weirs discharge coefficient. Three different performance indexes are used as comparing criteria for the evaluation of the model’s performances. The obtained results approved capability of GEP in prediction of trapezoidal and rectangular side weirs discharge coefficient. The results also revealed the influence of downstream Froude number for trapezoidal weir and upstream Froude number for rectangular weir in prediction of the discharge coefficient for both of side weirs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discharge%20coefficient" title="discharge coefficient">discharge coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20expression%20programming" title=" genetic expression programming"> genetic expression programming</a>, <a href="https://publications.waset.org/abstracts/search?q=trapezoidal%20weir" title=" trapezoidal weir"> trapezoidal weir</a> </p> <a href="https://publications.waset.org/abstracts/61052/predicting-trapezoidal-weir-discharge-coefficient-using-evolutionary-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61052.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">387</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">1273</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.

The trapezoidal labyrinth weir is a special type of weir in which crest length of the weir is increased to pass higher discharge. Experimental and numerical studies related to the coefficient of discharge of trapezoidal labyrinth weir in an open channel have been presented in the present study. Group Method of Data Handling (GMDH) with the transfer function of quadratic polynomial has been used to predict the coefficient of discharge for the side trapezoidal labyrinth weir. A new model is developed for coefficient of discharge of labyrinth weir by regression method. Generalized models for predicting the coefficient of discharge for labyrinth weir using Group Method of Data Handling (GMDH) network have also been developed.

The variation of discharge in the river generally produces a change in available draft for a vessel, particularly in the low flow season, which can impact the navigable water path, especially when the water depth is less than the normal one, which allows safe navigation for boats. The water depth is related to the bathymetry of the channel as well as the discharge. For a seasonal update of the navigation maps, a daily discharge value is required. Many novel approaches based on earth observation and remote sensing have been investigated for large rivers. However, it should be noted that most of these approaches are not currently able to directly estimate river discharge. This paper discusses the application of remote sensing tools using the analysis of the reflectance value of MODIS imagery and is combined with field measurements for the estimation of discharge. This approach is applied in the lower reach of the Congo River (Pool Malebo) for the period between 2019 and 2021. The correlation obtained between the observed discharge observed in the gauging station and the reflectance ratio time series is 0.81. In this context, a Discharge Reflectance Model (DRM) was developed to express discharge as a function of reflectance. This model introduces a non-contact method that allows discharge monitoring using earth observation. DRM was validated by field measurements using ADCP, in different sections on the Pool Malebo, over two different periods (dry and wet seasons), as well as by the observed discharge in the gauging station. The observed error between the estimated and measured discharge values ranges from 1 to 8% for the ADCP and from (1% to 11%) for the gauging station. The study of the uncertainties will give us the possibility to judge the robustness of the DRM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discharge%20monitoring" title="discharge monitoring">discharge monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=navigation" title=" navigation"> navigation</a>, <a href="https://publications.waset.org/abstracts/search?q=MODIS" title=" MODIS"> MODIS</a>, <a href="https://publications.waset.org/abstracts/search?q=empiric" title=" empiric"> empiric</a>, <a href="https://publications.waset.org/abstracts/search?q=ADCP" title=" ADCP"> ADCP</a>, <a href="https://publications.waset.org/abstracts/search?q=Congo%20River" title=" Congo River"> Congo River</a> </p> <a href="https://publications.waset.org/abstracts/160633/application-of-remote-sensing-and-in-situ-measurements-for-discharge-monitoring-in-large-rivers-case-of-pool-malebo-in-the-congo-river-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160633.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">91</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">1269</span> Treatment of Coal-Water-Oil Slurry Using High Voltage Discharge and Dielectric Barrier Discharge Plasmas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Song-Chol%20Pak">Song-Chol Pak</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Jun%20Kim"> Yong-Jun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hak-%20Chol%20Choe"> Hak- Chol Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Son%20Choe"> Yong-Son Choe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We converted the coal-water-oil slurry (CWOS) into an alternative fuel (AF) for internal combustion engines by high-voltage discharge (HVD) and dielectric barrier discharge (DBD) plasmas. After its treatments, the CWOS had the average coal size reduced from 12.95 to 8.26㎛, improved dispersibility, fewer deposits, and calorific value enhanced by 35%. The effects of some parameters were analyzed on the conversion of CWOS to AF, and the AF was characterized. The plasma-treated CWOS is similar to other liquid fuels in rheological properties and calorific value. It is therefore concluded that it can be directly employed in internal combustion engines with a little design modification.

Discharge coefficients generally vary from 0.6 to 0.95 depending on the type of the orifice. The tabulated value of discharge coefficients of various types of orifices available can be used in most common applications. The upstream and downstream flow condition of an orifice is hardly considered while choosing the discharge coefficient of an orifice. But literature shows that the discharge coefficient can be affected by the presence of cross flow. Cross flow is defined as the condition wherein; a fluid is injected nearly perpendicular to a flowing fluid. Most researchers have worked on water being injected into a cross-flow of water. The present work deals with water to gas systems in which water is injected in a normal direction into a flowing stream of gas. The test article used in the current work is called thermal regulator, which is used in a liquid rocket engine to reduce the temperature of hot gas tapped from the gas generator by injecting water into the hot gas so that a cooler gas can be supplied to the turbine. In a thermal regulator, water is injected through an orifice in a normal direction into the hot gas stream. But the injection orifice had been calibrated under backpressure by maintaining a stagnant gas medium at the downstream. The motivation of the present study aroused due to the observation of a lower Cd of the orifice in flight compared to the calibrated Cd. A systematic experimental investigation is carried out in this paper to study the effect of cross-flow on the discharge coefficient of an orifice in water to a gas system. The study reveals that there is an appreciable reduction in the discharge coefficient with cross flow compared to that without cross flow. It is found that the discharge coefficient greatly depends on the ratio of momentum of water injected to the momentum of the gas cross flow. The effective discharge coefficient of different orifices was normalized using the discharge coefficient without cross-flow and it is observed that normalized curves of effective discharge coefficient of different orifices with momentum ratio collapsing into a single curve. Further, an equation is formulated using the test data to predict the effective discharge coefficient with cross flow using the calibrated Cd value without cross flow. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20flow" title="cross flow">cross flow</a>, <a href="https://publications.waset.org/abstracts/search?q=discharge%20coefficient" title=" discharge coefficient"> discharge coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=orifice" title=" orifice"> orifice</a>, <a href="https://publications.waset.org/abstracts/search?q=momentum%20ratio" title=" momentum ratio"> momentum ratio</a> </p> <a href="https://publications.waset.org/abstracts/124296/experimental-investigation-on-the-effect-of-cross-flow-on-discharge-coefficient-of-an-orifice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124296.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">1266</span> Assessment of Solid Insulating Material Using Partial Discharge Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qasim%20Khan">Qasim Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Furkan%20Ahmad"> Furkan Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Asfar%20A.%20Khan"> Asfar A.

The model uses daily temperature data, daily precipitation data, and positive degree day factors for snow and ice melt. The model is calibrated for the period 1995-2001 and validated for 2002-2013, and demonstrates close agreements between observed and simulated discharge with Nash–Sutcliffe Efficiencies of 0.90 and 0.88, respectively. Furthermore, the Weather Research and Forecasting model projected temperature, and precipitation data from 2016-2050 are used for representative concentration pathways RCP4.5 and RCP8.5, and bias correction was done using a statistical approach for future discharge estimation. No drastic changes in future discharge are predicted for the emissions scenarios. The aggregate snow-ice melt contribution is 39% of total discharge in the period 1993-2013. Snow-ice melt contribution ranges from 35% to 63% during the high flow period (May to October), which constitutes 89% of annual discharge; in the low flow period (November to April) it ranges from 0.02% to 17%, which constitutes 11 % of the annual discharge. The snow-ice melt contribution to total discharge will increase gradually in the future and reach up to 45% in 2041-2050. From a sensitivity analysis, it is found that the combination of a 2°C temperature rise and 20% increase in precipitation shows a 10% increase in discharge. The study allows us to evaluate the impact of climate change in such basins and is also useful for the future prediction of discharge to define hydropower potential, inform other water resource management in the area, to understand future changes in snow-ice melt contribution to discharge, and offer a possible evaluation of future water quantity and availability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20variability" title="climate variability">climate variability</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20discharge%20projection" title=" future discharge projection"> future discharge projection</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20degree%20day" title=" positive degree day"> positive degree day</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20climate%20model" title=" regional climate model"> regional climate model</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resource%20management" title=" water resource management"> water resource management</a> </p> <a href="https://publications.waset.org/abstracts/69578/estimation-of-snow-and-ice-melt-contributions-to-discharge-from-the-glacierized-hunza-river-basin-karakoram-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69578.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">290</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">1264</span> Numerical Analysis of Swirling Chamber Using Improved Delayed Detached Eddy Simulation Turbulence Model </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamad%20M.%20Alhajeri">Hamad M.

However, these alloys impose challenges while using conventional machining technologies. On the other hand, Micro-Electro-Discharge machining (micro-EDM) is a non-conventional machining method that uses controlled sparks energy to remove material irrespective of the materials hardness. There has been always a huge interest from the industries for developing optimum methodology and parameters in order to enhance the productivity of micro-EDM in terms of reducing machining time and tool wear for different alloys. Therefore, the aims of this study are to investigate the effects of the micro-EDM process parameters, in order to find their optimal values. The input process parameters include voltage, capacitance, and electrode rotational speed, whereas the output parameters considered are machining time, entrance diameter of hole, overcut, tool wear, and crater size. The surface morphology and element characterization are also investigated with the use of SEM and EDX analysis. The experimental result indicates the reduction of machining time with the increment of discharge energy. Discharge energy also contributes to the enlargement of entrance diameter as well as overcut. In addition, tool wears show reduction with the increase of discharge energy. Moreover, crater size is found to be increased in size along with the increment of discharge energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=micro%20holes" title="micro holes">micro holes</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20EDM" title=" micro EDM"> micro EDM</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni%20Alloy" title=" Ni Alloy"> Ni Alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=discharge%20energy" title=" discharge energy"> discharge energy</a> </p> <a href="https://publications.waset.org/abstracts/56332/an-experimental-study-on-the-effect-of-operating-parameters-during-the-micro-electro-discharge-machining-of-ni-based-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56332.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">274</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">1259</span> Reliable Method for Estimating Rating Curves in the Natural Rivers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20%20Ahmadi">Arash Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirreza%20Kavousizadeh"> Amirreza Kavousizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanaz%20Heidarzadeh"> Sanaz Heidarzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stage-discharge curve is one of the conventional methods for continuous river flow measurement.

For this purpose, multivariate relationships are used to determine the mean velocity in a cross-section. The unknown exponents of the proposed relationship have been obtained by using the second version of the Strength Pareto Evolutionary Algorithm (SPEA2), and the appropriate equation was selected by applying the TOPSIS (Technique for Order Preferences by Similarity to an Ideal Solution) approach.

The maximum head expected over the weir, the total upstream water height and the downstream water height of the impact in the constant bed of the open channel were measured. The discharge was measured using a tank put right after the open channel. In addition, the discharge and the upstream velocity were also calculated using already known equations. The main finding is that the relative error percentage for the majority of the experimental measurements is ± 4%, meaning that the calculation of the discharge with a sharp-crested weir gives very good results compared to the numerical results from known equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sharp-crested%20weir" title="sharp-crested weir">sharp-crested weir</a>, <a href="https://publications.waset.org/abstracts/search?q=weir%20height" title=" weir height"> weir height</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20measurement" title=" flow measurement"> flow measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20channel%20flow" title=" open channel flow"> open channel flow</a> </p> <a href="https://publications.waset.org/abstracts/117918/experimental-study-of-discharge-with-sharp-crested-weirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117918.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">139</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">1257</span> Effect of Addition Rate of Expansive Additive on Autogenous Shrinkage and Delayed Expansion of Ultra-High Strength Mortar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yulu%20Zhang">Yulu Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Atushi%20Teramoto"> Atushi Teramoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Taka-Aki%20Ohkubo"> Taka-Aki Ohkubo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of expansive additives on autogenous shrinkage and delayed expansion of ultra-high strength mortar was explored. The specimens made for the study were composed of ultra-high strength mortar, which was mixed with ettringite-lime composite type expansive additive. Two series of experiments were conducted with the specimens. The experimental results confirmed that the autogenous shrinkage of specimens was effectively decreased by increasing the proportion of the expansive additive. On the other hand, for the specimens, which had 7% expansive additive, and were cured for seven days at a constant temperature of 20°C, and then cured for a long time in either in an underwater, moist (Relative humidity: 100%) or dry air (Relative humidity: 60%) environment, excessively large expansion strain occurred. Specifically, typical turtle shell-like swelling expansion cracks were confirmed in the specimens that underwent long-term curing in an underwater and moist environment. According to the result of hydration analysis, the formation of expansive substances, calcium hydroxide and alumina, ferric oxide, tri-sulfate contribute to the occurrence of delayed expansion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra-high%20strength%20mortar" title="ultra-high strength mortar">ultra-high strength mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=expansive%20additive" title=" expansive additive"> expansive additive</a>, <a href="https://publications.waset.org/abstracts/search?q=autogenous%20shrinkage" title=" autogenous shrinkage"> autogenous shrinkage</a>, <a href="https://publications.waset.org/abstracts/search?q=delayed%20expansion" title=" delayed expansion"> delayed expansion</a> </p> <a href="https://publications.waset.org/abstracts/72289/effect-of-addition-rate-of-expansive-additive-on-autogenous-shrinkage-and-delayed-expansion-of-ultra-high-strength-mortar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72289.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">239</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">1256</span> Mathematical Modeling of Drip Emitter Discharge of Trapezoidal Labyrinth Channel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Philipova">N.

The impact of the dentate angle, the dentate spacing, and the dentate height are studied among the geometric parameters of the labyrinth channel. Numerical simulations of the water flow movement are performed according to central cubic composite design using Commercial codes GAMBIT and FLUENT. Inlet pressure of the dripper is set up to be 1 bar. The objective of this paper is to derive a mathematical model of the emitter discharge depending on the dentate angle, the dentate spacing, the dentate height of the labyrinth channel. As a result, the obtained mathematical model is a second-order polynomial reporting 2-way interactions among the geometric parameters. The dentate spacing has the most important and positive influence on the emitter discharge, followed by the simultaneous impact of the dentate spacing and the dentate height. The dentate angle in the observed interval has no significant effect on the emitter discharge. The obtained model can be used as a basis for a future emitter design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drip%20irrigation" title="drip irrigation">drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=labyrinth%20channel%20hydrodynamics" title=" labyrinth channel hydrodynamics"> labyrinth channel hydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynolds%20stress%20model." title=" Reynolds stress model."> Reynolds stress model.</a> </p> <a href="https://publications.waset.org/abstracts/75760/mathematical-modeling-of-drip-emitter-discharge-of-trapezoidal-labyrinth-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75760.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">184</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">1255</span> Study of Tool Shape during Electrical Discharge Machining of AISI 52100 Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arminder%20Singh%20Walia">Arminder Singh Walia</a>, <a href="https://publications.waset.org/abstracts/search?q=Vineet%20Srivastava"> Vineet Srivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivek%20Jain"> Vivek Jain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Electrical Discharge Machining (EDM) operations, the workpiece confers to the shape of the tool.

Thus, in this work, an attempt has been made to study the effect of process parameters on the shape of the tool. Copper has been used as the tool material for the machining of AISI 52100 die steel. The shape of the tool has been evaluated by determining the difference in out of roundness of tool before and after machining.

Therefore, adding a bracing system with the capability of preserving the capacity of high energy absorption and controlling displacements without a considerable increase in the stiffness is quite important. This paper investigates the retrofitting of a single storey steel moment frame through a delayed wire-rope bracing system using a middle steel plate. In this model, the steel plate lies where the wire ropes meet, and the model geometry is such that the cables are continuously under tension so that they can take the most advantage of the inherent potential they have in tolerating tensile stress. Using the steel plate also reduces the system stiffness considerably compared to cross bracing systems and preserves the ductile frame’s energy absorption capacity. In this research, the software models of delayed wire-rope bracing system have been studied, validated, and compared with other researchers’ laboratory test results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title="cyclic loading">cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=delayed%20wire%20rope%20bracing" title=" delayed wire rope bracing"> delayed wire rope bracing</a>, <a href="https://publications.waset.org/abstracts/search?q=ductile%20moment%20frame" title=" ductile moment frame"> ductile moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis%20curve" title=" hysteresis curve"> hysteresis curve</a> </p> <a href="https://publications.waset.org/abstracts/69615/enhancing-seismic-performance-of-ductile-moment-frames-with-delayed-wire-rope-bracing-using-middle-steel-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69615.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">289</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">1251</span> 2D RF ICP Torch Modelling with Fluid Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Labiod">Mokhtar Labiod</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Ikhlef"> Nabil Ikhlef</a>, <a href="https://publications.waset.org/abstracts/search?q=Keltoum%20Bouherine"> Keltoum Bouherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Leroy"> Olivier Leroy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A numerical model for the radio-frequency (RF) Argon discharge chamber is developed to simulate the low pressure low temperature inductively coupled plasma. This model will be of fundamental importance in the design of the plasma magnetic control system. Electric and magnetic fields inside the discharge chamber are evaluated by solving a magnetic vector potential equation. To start with, the equations of the ideal magnetohydrodynamics theory will be presented describing the basic behaviour of magnetically confined plasma and equations are discretized with finite element method in cylindrical coordinates. The discharge chamber is assumed to be axially symmetric and the plasma is treated as a compressible gas. Plasma generation due to ionization is added to the continuity equation. Magnetic vector potential equation is solved for the electromagnetic fields. A strong dependence of the plasma properties on the discharge conditions and the gas temperature is obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct-coupled%20model" title="direct-coupled model">direct-coupled model</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic" title=" magnetohydrodynamic"> magnetohydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20torch%20simulation" title=" plasma torch simulation"> plasma torch simulation</a> </p> <a href="https://publications.waset.org/abstracts/38779/2d-rf-icp-torch-modelling-with-fluid-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38779.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">433</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">1250</span> Development of Partial Discharge Defect Recognition and Status Diagnosis System with Adaptive Deep Learning</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=Bo-wei%20Wu"> Bo-wei Wu</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> This paper proposes a power equipment diagnosis system based on partial discharge (PD), which is characterized by increasing the readability of experimental data and the convenience of operation. This system integrates a variety of analysis programs of different data formats and different programming languages and then establishes a set of interfaces that can follow and expand the structure, which is also helpful for subsequent maintenance and innovation. This study shows a case of using the developed Convolutional Neural Networks (CNN) to integrate with this system, using the designed model architecture to simplify the complex training process. It is expected that the simplified training process can be used to establish an adaptive deep learning experimental structure. By selecting different test data for repeated training, the accuracy of the identification system can be enhanced. On this platform, the measurement status and partial discharge pattern of each equipment can be checked in real time, and the function of real-time identification can be set, and various training models can be used to carry out real-time partial discharge insulation defect identification and insulation state diagnosis. When the electric power equipment entering the dangerous period, replace equipment early to avoid unexpected electrical accidents. <p class="card-text"><strong>Keywords:</strong> <a
