However, the generated descriptions of their systems are often less informative and attractive because of lacking training datasets or the limitation of these approaches, which often use templates or statistical methods. In this paper, we explore a method to generate production descriptions by using the GPT-2 model. In addition, we apply text paraphrasing and task-adaptive pretraining techniques to improve the qualify of descriptions generated from the GPT-2 model. Experiment results show that our models outperform the baseline model through automatic evaluation and human evaluation. Especially, our methods achieve a promising result not only on the seen test set but also in the unseen test set. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GPT-2" title="GPT-2">GPT-2</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20description" title=" product description"> product description</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=task-adaptive" title=" task-adaptive"> task-adaptive</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20model" title=" language model"> language model</a>, <a href="https://publications.waset.org/abstracts/search?q=pretraining" title=" pretraining"> pretraining</a> </p> <a href="https://publications.waset.org/abstracts/141901/generating-product-description-with-generative-pre-trained-transformer-2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141901.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">197</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">284</span> A Method for Processing Unwanted Target Caused by Reflection in Secondary Surveillance Radar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khanh%20D.Do">Khanh D.Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Loi%20V.Nguyen"> Loi V.Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanh%20N.Nguyen"> Thanh N.Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Thang%20M.Nguyen"> Thang M.Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Vu%20T.Tran"> Vu T.Tran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Along with the development of Secondary surveillance radar (SSR) in air traffic surveillance systems, the Multipath phenomena has always been a noticeable problem.

Those low-rise buildings have created well-knitted, robust communities, so much to the point that in most complexes, all families in one housing block would know each other, occasionally interact and provide supports in need. To understand how the community of collective housing complexes have developed and maintained in order to adapt their advantages into modern housing designs, the study is executed on the site of Nguyen Cong Tru KTT. This is one of the oldest KTT in Hanoi, completed in 1954. The complex also has an unique characteristic that is closely related to its community: the symbiotic relationship with Hom – a flea market that has been co-developing with Nguyen Cong Tru KTT since its beginning. The research consists of three phases: the first phase is a sociological investigation with Nguyen Cong Tru KTT’s current residents and a site survey on the complex’s economic and architectural characteristics. In the second phase, the collected data is analyzed to find out people’s opinions with the KTT’s concerning their satisfaction with the current housing status, floor plan organization, community, the relationship between the KTT’s dedicated public spaces with the flea market and their usage. Simultaneously, the master plan and gathered information regarding current architectural characteristics of the complex are also inspected. On the third phase, the analyses’ results will provide information regarding the issues, positive trends and significant historical features of the complex’s architecture in order to generate suitable proposals for the redesigning project of Nguyen Cong Tru KTT, a design focused on vitalizing modern apartments’ communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collective%20house%20community" title="collective house community">collective house community</a>, <a href="https://publications.waset.org/abstracts/search?q=collective%20house%20public%20space" title=" collective house public space"> collective house public space</a>, <a href="https://publications.waset.org/abstracts/search?q=community-focused" title=" community-focused"> community-focused</a>, <a href="https://publications.waset.org/abstracts/search?q=redesigning%20Nguyen%20Cong%20Tru%20KTT" title=" redesigning Nguyen Cong Tru KTT"> redesigning Nguyen Cong Tru KTT</a>, <a href="https://publications.waset.org/abstracts/search?q=sociological%20investigation" title=" sociological investigation "> sociological investigation </a> </p> <a href="https://publications.waset.org/abstracts/68487/a-sociological-investigation-on-the-population-and-public-spaces-of-nguyen-cong-tru-a-soviet-style-collective-housing-complex-in-hanoi-in-regards-to-its-new-community-focused-architectural-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68487.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">281</span> A Novel Search Pattern for Motion Estimation in High Efficiency Video Coding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phong%20Nguyen">Phong Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Phap%20Nguyen"> Phap Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Thang%20Nguyen"> Thang Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High Efficiency Video Coding (HEVC) or H.265 Standard fulfills the demand of high resolution video storage and transmission since it achieves high compression ratio. However, it requires a huge amount of calculation. Since Motion Estimation (ME) block composes about 80 % of calculation load of HEVC, there are a lot of researches to reduce the computation cost. In this paper, we propose a new algorithm to lower the number of Motion Estimation’s searching points. The number of computing points in search pattern is down from 77 for Diamond Pattern and 81 for Square Pattern to only 31. Meanwhile, the Peak Signal to Noise Ratio (PSNR) and bit rate are almost equal to those of conventional patterns. The motion estimation time of new algorithm reduces by at 68.23%, 65.83%compared to the recommended search pattern of diamond pattern, square pattern, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motion%20estimation" title="motion estimation">motion estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=wide%20diamond" title=" wide diamond"> wide diamond</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20pattern" title=" search pattern"> search pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=H.265" title=" H.265"> H.265</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20zone%20search" title=" test zone search"> test zone search</a>, <a href="https://publications.waset.org/abstracts/search?q=HM%20software" title=" HM software"> HM software</a> </p> <a href="https://publications.waset.org/abstracts/22368/a-novel-search-pattern-for-motion-estimation-in-high-efficiency-video-coding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22368.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">612</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">280</span> Numerical Modelling of a Vacuum Consolidation Project in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Trong%20Nghia">Nguyen Trong Nghia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Huu%20Uy%20Vu"> Nguyen Huu Uy Vu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dang%20Huu%20Phuoc"> Dang Huu Phuoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Shukla"> Sanjay Kumar Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Gia%20Lam"> Le Gia Lam</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Van%20Cuong"> Nguyen Van Cuong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a matching scheme for selection of soil/drain properties in analytical solution and numerical modelling (axisymmetric and plane strain conditions) of a ground improvement project by using Prefabricated Vertical Drains (PVD) in combination with vacuum and surcharge preloading. In-situ monitoring data from a case history of a road construction project in Vietnam was adopted in the back-analysis. Analytical solution and axisymmetric analysis can approximate well the field data meanwhile the horizontal permeability need to be adjusted in plane strain scenario to achieve good agreement. In addition, the influence zone of the ground treatment was examined. The residual settlement was investigated to justify the long-term settlement in compliance with the design code. Moreover, the degree of consolidation of non-PVD sub-layers was also studied by means of two different approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20modelling" title="numerical modelling">numerical modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated%20vertical%20drains" title=" prefabricated vertical drains"> prefabricated vertical drains</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20consolidation" title=" vacuum consolidation"> vacuum consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20soil" title=" soft soil"> soft soil</a> </p> <a href="https://publications.waset.org/abstracts/96963/numerical-modelling-of-a-vacuum-consolidation-project-in-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96963.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">230</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">279</span> An Application of Hip Arthroscopy after Acute Injury - A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Nguyen%20Binh">Le Nguyen Binh</a>, <a href="https://publications.waset.org/abstracts/search?q=Luong%20Xuan%20Binh"> Luong Xuan Binh</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Van%20Tuan"> Le Van Tuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Binh%20Duong"> Tran Binh Duong</a>, <a href="https://publications.waset.org/abstracts/search?q=Truong%20Nguyen%20Khanh%20Hung"> Truong Nguyen Khanh Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Le%20Hoang%20Son"> Do Le Hoang Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Pham%20Quang%20Vinh"> Pham Quang Vinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Quoc%20Huy"> Hoang Quoc Huy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Bach"> Nguyen Bach</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quoc%20Khanh%20Le"> Nguyen Quoc Khanh Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiunn%20Horng%20Kang"> Jiunn Horng Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Traumatic hip dislocation is an emergency in young adult which can cause avascular necrosis of femoral head or osteoarthritis of hip joint. The reasons for these may be the loose body of bony or chondral fragments, which are difficult to be detected on CT scan or MRI. In those cases, Hip arthroscopy may be the method of choice for diagnosis and treatment of loose bodies in hip joint after traumatic dislocation. Methods: A case report is performed. A 55-year-old male patient was under hip arthroscopy to retrieve the loose body in the right hip joint. Results: The patient’s hip was reduced under anesthesia in the opeation room. Xray and CT scan post-reduction showed that his right hip was wide and a small fragment of femoral head (< 5mm) locking inside the joint. A hip arthroscopy was done to take the fragment out. Post-operation, the patient went under rehabilition. After 6 months, he can walk with full-weight bearing; no further dislocaion was noted, and the Harris score was 84 points. Conclusions: Although acute traumatic injury of hip joint is usually treated with open surgeries, these methods have many drawbacks, such as soft tissue destruction, blood-loss,….Despite its technical requirement, hip arthroscopy is less invasive and effective treatment. Therefore, it may be an alternative treatment for a traumatic hip injury and can be applied frequently in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hip%20dislocation" title="hip dislocation">hip dislocation</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20arthroscopy" title=" hip arthroscopy"> hip arthroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20osteoarthritis" title=" hip osteoarthritis"> hip osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20hip%20trauma" title=" acute hip trauma"> acute hip trauma</a> </p> <a href="https://publications.waset.org/abstracts/162276/an-application-of-hip-arthroscopy-after-acute-injury-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162276.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">86</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">278</span> An Assessment of Tai Chi Exercise on Cognitive Performance in Vietnamese Older Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hung%20Manh%20Nguyen">Hung Manh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Duong%20Dai%20Nguyen"> Duong Dai Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To evaluate the effects of Tai Chi exercise on cognitive performance of community-dwelling elderly in Vinh city, Vietnam.

The ambiguity resolution method is an adaptive implementation of the coincidence algorithm, which is implemented on a two-dimensional (2D) range-velocity matrix to resolve range and velocity ambiguities simultaneously, with a proposed clustering filter to enhance the anti-error ability of the system. Here we consider the scenario of multiple target environments. The ghost target removal process, which is based on the power after Doppler processing, is proposed to mitigate ghosting detections to enhance the performance of ground-based radars using a short PRF schedule in multiple target environments. Simulation results on a ground-based pulsed Doppler radar model will be presented to show the effectiveness of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambiguity%20resolution" title="ambiguity resolution">ambiguity resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=coincidence%20algorithm" title=" coincidence algorithm"> coincidence algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20PRF" title=" medium PRF"> medium PRF</a>, <a href="https://publications.waset.org/abstracts/search?q=ghosting%20removal" title=" ghosting removal"> ghosting removal</a> </p> <a href="https://publications.waset.org/abstracts/154205/ambiguity-resolution-for-ground-based-pulse-doppler-radars-using-multiple-medium-pulse-repetition-frequency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154205.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">152</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">276</span> Some Observations on the Preparation of Zinc Hydroxide Nitrate Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krasimir%20Ivanov">Krasimir Ivanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Elitsa%20Kolentsova"> Elitsa Kolentsova</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Nguyen"> Nguyen Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Peltekov"> Alexander Peltekov</a>, <a href="https://publications.waset.org/abstracts/search?q=Violina%20Angelova"> Violina Angelova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The nanosized zinc hydroxide nitrate has been recently estimated as perspective foliar fertilizer, which has improved zinc solubility, but low phytotoxicity, in comparison with ZnO and other Zn containing compounds.

The mechanism of this disease is a failure of hepatic excretion of copper to the bile, and it leads to copper deposits in the liver and other organs. Most clinical symptoms of Wilson’s disease can present as liver disease and/or neurologic disease. Objective: The goal of the study is prenatal diagnosis for pregnant women at high risk of Wilson’s disease in Northern Vietnam. Material and method: Three probands with clinically diagnosed liver disease were detected in the mutations of 21 exons and exon-intron boundaries of the ATP7B gene by direct Sanger-sequencing. Prenatal diagnoses were performed by amniotic fluid sampling from pregnant women in the 16th-18th weeks of pregnancy after the genotypes of parents with the probands were identified. Result: A total of three different mutations of the probands, including of S105*, P1052L, P1273G, were detected. Among three fetuses which underwent prenatal genetic testing, one fetus was homozygote; two fetuses were carriers. Conclusion: Genetic testing provided a useful method for prenatal diagnosis, and is a basis for genetic counseling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATP7B%20gene" title="ATP7B gene">ATP7B gene</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20testing" title=" genetic testing"> genetic testing</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20diagnosis" title=" prenatal diagnosis"> prenatal diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=pedigree" title=" pedigree"> pedigree</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilson%20disease" title=" Wilson disease"> Wilson disease</a> </p> <a href="https://publications.waset.org/abstracts/58248/application-of-atp7b-gene-mutation-analysis-in-prenatal-diagnosis-of-wilsons-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58248.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">455</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">274</span> Flood Planning Based on Risk Optimization: A Case Study in Phan-Calo River Basin in Vinh Phuc Province, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quang%20Kim">Nguyen Quang Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thu%20Hien"> Nguyen Thu Hien</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thien%20Dung"> Nguyen Thien Dung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flood disasters are increasing worldwide in both frequency and magnitude. Every year in Vietnam, flood causes great damage to people, property, and environmental degradation. The flood risk management policy in Vietnam is currently updated. The planning of flood mitigation strategies is reviewed to make a decision how to reach sustainable flood risk reduction. This paper discusses the basic approach where the measures of flood protection are chosen based on minimizing the present value of expected monetary expenses, total residual risk and costs of flood control measures. This approach will be proposed and demonstrated in a case study for flood risk management in Vinh Phuc province of Vietnam. Research also proposed the framework to find a solution of optimal protection level and optimal measures of the flood. It provides an explicit economic basis for flood risk management plans and interactive effects of options for flood damage reduction.

The general scope of the investigations is improving the stability of the Vietnam power system and giving the EVNNLDC staff the capability to decide how to deal with expected stability challenges in the future, which are related to the very fast growth of the system. Rapid system growth leads to a very high demand of power transmission from North to South. This was investigated by stability studies of interconnected power system with neighboring countries. These investigations are performed in close cooperation and coordination with the EVNNLDC project team. This important project includes data collection, measurement, model validation and investigation of relevant stability phenomena as well as training of the EVNNLDC staff. Generally, the power system of Vietnam has good voltage and dynamic stability. The main problems are related to the longitudinal system with more power generation in the North and Center, especially hydro power, and load centers in the South of Vietnam. Faults on the power transmission system from North to South risks the stability of the entire system due to a high power transfer from North to South and high loading of the 500 kV backbone. An additional problem is the weak connection to Cambodia power system which leads to interarea oscillations mode. Therefore, strengthening the power transfer capability by new 500kV lines or HVDC connection and balancing the power generation across the country will solve many challenges. Other countermeasures, such as wide area load shedding, PSS tuning and correct SVC placement will improve and stabilize the power system as well. Primary frequency reserve should be increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20power%20transmission%20system%20studies" title="dynamic power transmission system studies">dynamic power transmission system studies</a>, <a href="https://publications.waset.org/abstracts/search?q=blackout%20prevention" title=" blackout prevention"> blackout prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20interconnection" title=" power system interconnection"> power system interconnection</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/58895/enhancing-the-stability-of-vietnamese-power-system-from-theory-to-practical" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58895.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">361</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">272</span> Comparison between Continuous Genetic Algorithms and Particle Swarm Optimization for Distribution Network Reconfiguration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linh%20Nguyen%20Tung">Linh Nguyen Tung</a>, <a href="https://publications.waset.org/abstracts/search?q=Anh%20Truong%20Viet"> Anh Truong Viet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nghien%20Nguyen%20Ba"> Nghien Nguyen Ba</a>, <a href="https://publications.waset.org/abstracts/search?q=Chuong%20Trinh%20Trong"> Chuong Trinh Trong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a reconfiguration methodology based on a continuous genetic algorithm (CGA) and particle swarm optimization (PSO) for minimizing active power loss and minimizing voltage deviation.

Its expensive computational cost encouraged many researchers to improve the speed of the algorithm. Recent works proposed schemes that work on parallel computing platforms such as CUDA.

In this paper, we propose global suppression heuristic to boost the conver-gence process of the algorithm. A parallel implementation of GraphCut algorithm on CUDA designed for the image stitching problem is introduced. Our method achieves up to 3× time boost on the graph of size 80 × 480 compared to the best sequential GraphCut algorithm while achieving satisfactory stitched images, suitable for panorama applications.

All these results of quantum wire compared with bulk semiconductors and superlattices to show the difference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=The%20photon-drag%20effect" title="The photon-drag effect">The photon-drag effect</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20constant%20current%20density" title=" the constant current density"> the constant current density</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20wire" title=" quantum wire"> quantum wire</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20potential" title=" parabolic potential"> parabolic potential</a> </p> <a href="https://publications.waset.org/abstracts/53802/the-photon-drag-effect-in-cylindrical-quantum-wire-with-a-parabolic-potential" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53802.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">422</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">267</span> External Store Safe Separation Evaluation Process Implementing CFD and MIL-HDBK-1763</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thien%20Bach%20Nguyen">Thien Bach Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nhu-Van%20Nguyen"> Nhu-Van Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Phi-Minh%20Nguyen"> Phi-Minh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Minh%20Hien%20Dao"> Minh Hien Dao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The external store safe separation evaluation process implementing CFD and MIL-HDBK-1763 is proposed to support the evaluation and compliance of the external store safe separation with the extensive using CFD and the criteria from MIL-HDBK-1763. The criteria of safe separation are researched and investigated for the various standards and handbooks such as MIL-HDBK-1763, MIL-HDBK-244A, AGARD-AG-202 and AGARD-AG-300 to acquire the appropriate and tailored values and limits for the typical applications of external carriages and aircraft fighters. The CFD and 6DOF simulations are extensively used in ANSYS 2023 R1 Software for verification and validation of moving unstructured meshes and solvers by calibrating the position, aerodynamic forces and moments of the existing air-to-ground missile models. The verified CFD and 6DoF simulation separation process is applied and implemented for the investigation of the typical munition separation phenomena and compliance with the tailored requirements of MIL-HDBK-1763. The prediction of munition trajectory parameters under aircraft aerodynamics interference and specified rack unit consideration after munition separation is provided and complied with the tailored requirements to support the safe separation evaluation of improved and newly external store munition before the flight test performed. The proposed process demonstrates the effectiveness and reliability in providing the understanding of the complicated store separation and the reduction of flight test sorties during the improved and new munition development projects by extensively using the CFD and tailoring the existing standards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=external%20store%20separation" title="external store separation">external store separation</a>, <a href="https://publications.waset.org/abstracts/search?q=MIL-HDBK-1763" title=" MIL-HDBK-1763"> MIL-HDBK-1763</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20meshes" title=" moving meshes"> moving meshes</a>, <a href="https://publications.waset.org/abstracts/search?q=flight%20test%20data" title=" flight test data"> flight test data</a>, <a href="https://publications.waset.org/abstracts/search?q=munition." title=" munition."> munition.</a> </p> <a href="https://publications.waset.org/abstracts/192199/external-store-safe-separation-evaluation-process-implementing-cfd-and-mil-hdbk-1763" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192199.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">266</span> Mutation Analysis of the ATP7B Gene in 43 Vietnamese Wilson’s Disease Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huong%20M.%20T.%20Nguyen">Huong M.

The mechanism of this disease is the failure of hepatic excretion of copper to bile, and leads to copper deposits in the liver and other organs. The <em>ATP7B</em> gene is located on the long arm of chromosome 13 (13q14.3). This study aimed to investigate the gene mutation in the Vietnamese patients with WD, and make a presymptomatic diagnosis for their familial members. Forty-three WD patients and their 65 siblings were identified as having <em>ATP7B</em> gene mutations. Genomic DNA was extracted from peripheral blood samples; 21 exons and exon-intron boundaries of the <em>ATP7B</em> gene were analyzed by direct sequencing. We recognized four mutations ([R723=; H724Tfs*34], V1042Cfs*79, D1027H, and IVS6+3A>G) in the sum of 20 detectable mutations, accounting for 87.2% of the total. Mutation S105* was determined to have a high rate (32.6%) in this study. The hotspot regions of <em>ATP7B</em> were found at exons 2, 16, and 8, and intron 14, in 39.6 %, 11.6 %, 9.3%, and 7 % of patients, respectively. Among nine homozygote/compound heterozygote siblings of the patients with WD, three individuals were determined as asymptomatic by screening mutations of the probands. They would begin treatment after diagnosis. In conclusion, 20 different mutations were detected in 43 WD patients. Of this number, four novel mutations were explored, including [R723=; H724Tfs*34], V1042Cfs*79, D1027H, and IVS6+3A>G. The mutation S105* is the most prevalent and has been considered as a biomarker that can be used in a rapid detection assay for diagnosis of WD patients. Exons 2, 8, and 16, and intron 14 should be screened initially for WD patients in Vietnam. Based on risk profile for WD, genetic testing for presymptomatic patients is also useful in diagnosis and treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATP7B%20gene" title="ATP7B gene">ATP7B gene</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation%20detection" title=" mutation detection"> mutation detection</a>, <a href="https://publications.waset.org/abstracts/search?q=presymptomatic%20diagnosis" title=" presymptomatic diagnosis"> presymptomatic diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnamese%20Wilson%E2%80%99s%20disease" title=" Vietnamese Wilson’s disease"> Vietnamese Wilson’s disease</a> </p> <a href="https://publications.waset.org/abstracts/58250/mutation-analysis-of-the-atp7b-gene-in-43-vietnamese-wilsons-disease-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58250.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">380</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">265</span> Low-Cost IoT System for Monitoring Ground Propagation Waves due to Construction and Traffic Activities to Nearby Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lan%20Nguyen">Lan Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Kien%20Le%20Tan"> Kien Le Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bao%20Nguyen%20Pham%20Gia"> Bao Nguyen Pham Gia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the high cost, specialized dynamic measurement devices for industrial lands are difficult for many colleges to equip for hands-on teaching.

This paper deals with analytical solution for the stresses, strains, and deflections of double-layered asphalt pavement structure. This solution is based on the homogeneous half-space of layered theory developed by Burmister (1943). The partial interaction between the layers is taken into account by considering an interface bonding behavior which is obtained by push-out shear test. Numerical applications considering three cases of bonding (unbonded, partially bonded, and fully bonded overlays) are carried out to the influence of the interface bonding on the structural behavior of asphalt pavement under static loading. Further, it was observed that numerical results indicate that the horizontal shear reaction modulus at the interface (Ks) will significantly affect pavement structure behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title="analytical solution">analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20bonding" title=" interface bonding"> interface bonding</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20test%20keyword" title=" shear test keyword"> shear test keyword</a>, <a href="https://publications.waset.org/abstracts/search?q=double-layered%20asphalt" title=" double-layered asphalt"> double-layered asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20reaction%20modulus" title=" shear reaction modulus"> shear reaction modulus</a> </p> <a href="https://publications.waset.org/abstracts/83012/numerical-modeling-analysis-for-the-double-layered-asphalt-pavement-structure-behavior-with-interface-bonding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83012.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">230</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">262</span> Superior Mesenteric Artery Syndrome in Patient with Snake Bites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Dang%20Duc">Nguyen Dang Duc</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Phuong%20Sinh"> Nguyen Phuong Sinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Lam%20Nguyen%20Hong%20Anh"> Lam Nguyen Hong Anh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Superior mesenteric artery (SMA) syndrome is a rare cause of high-section intestinal obstruction. SMA syndrome is characterized by compression of the third segment of the duodenum due to the narrowing of the distance between the superior mesenteric artery and the abdominal aorta. The main clinical signs of SMA syndrome are high intestinal obstruction, such as postprandial vomiting, epigastric pain, early feeling of abdominal fullness, and indigestion. Abdominal computed tomography plays an important role in diagnosis. There are two main methods of treating SMA syndrome that are conservative and surgical treatment. We report a clinical case of an 18-year-old male patient admitted to the hospital because of a Bungarus snake bit in the second hour, to the twelfth day of treatment, the patient developed diarrhea that lasted until the twenty-fourth day of treatment. On the twenty-fifth day of treatment, the patient lost 16 kilograms (from 56 down to 40). The patient had symptoms of vomiting after eating, indigestion, and epigastric pain. On abdominal computed tomography, the angle created by the superior mesenteric artery and the abdominal aorta was 17 degrees, the distance between the two arteries was 3.8 millimeters, light dilation and stagnation of the D1 and D2 segment of the duodenum with gas and watery level inside segment D3 and D4 of the duodenum and this segment was constricted. This patient was diagnosed with superior mesenteric artery syndrome with the Bungarus snake bites. Currently, the patient was treated with feeding through a jejunal tube each other intravenous nutrition. Finally, The patient was discharged and returned to his house on the forty-fifth day of treatment. We reported this clinical case to introduce clinical and paraclinical signs, diagnose, and methods treated for patient having SMA syndrome. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=superior%20mesenteric%20artery%20syndrome" title="superior mesenteric artery syndrome">superior mesenteric artery syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=Bungarus%20snake%20bites" title=" Bungarus snake bites"> Bungarus snake bites</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20weight" title=" loss weight"> loss weight</a> </p> <a href="https://publications.waset.org/abstracts/195450/superior-mesenteric-artery-syndrome-in-patient-with-snake-bites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195450.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">3</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">261</span> Optimized Control of Roll Stability of Missile using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pham%20Van%20Hung">Pham Van Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Trong%20Hieu"> Nguyen Trong Hieu</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Quoc%20Dinh"> Le Quoc Dinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Kiem%20Chien"> Nguyen Kiem Chien</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Dinh%20Hieu"> Le Dinh Hieu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article focuses on the study of automatic flight control on missiles during operation.

A two-loop control structure for the Missile Roll channel is proposed, with the inner loop controlling the Missile Roll rate and the outer loop controlling the Missile Roll angle. To determine the optimal control parameters, a genetic algorithm is applied.

The aerodynamic characteristics of this turbine were investigated by both theoretical and numerical approaches. The optimal design procedure was first proposed to enhance the power coefficient under various effects, such as airfoil type, number of blades, solidity, aspect ratio, and tip speed ratio. As a result, the overall design of the 10kW HDWT was well achieved, and the power characteristic of this turbine was found by numerical approach. Additionally, the maximum power coefficient predicted is up to 0.41 at the tip speed ratio of 3.7 and wind speed of 8 m/s. Particularly, a generalized correlation of power coefficient with tip speed ratio and wind speed is first proposed. These results obtained are very useful for enhancing the performance of the HDWTs placed in a country with high wind power potential like Vietnam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20multiple%20stream%20tube" title=" double multiple stream tube"> double multiple stream tube</a>, <a href="https://publications.waset.org/abstracts/search?q=h-darrieus%20wind%20turbine" title=" h-darrieus wind turbine"> h-darrieus wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/163982/an-investigation-on-designing-and-enhancing-the-performance-of-h-darrieus-wind-turbine-of-10kw-at-the-medium-range-of-wind-speed-in-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163982.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">119</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">259</span> The Correlation between Self-Regulated Learning Strategies and Reading Proficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thu%20Ha">Nguyen Thu Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Vu%20Viet%20Phuong"> Vu Viet Phuong</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Thi%20Tieu%20Yen"> Do Thi Tieu Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thi%20Thanh%20Ha"> Nguyen Thi Thanh Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This semi-experimental research investigated the correlation between 42 English as a foreign language (EFL) sophomores' self-regulated learning strategies (SRL) use and their reading comprehension in the Vietnamese context.

Contrary to the alternative hypothesis, teaching learners SRL approaches had a statistically significant influence on reading comprehension. The findings may aid educators in teaching reading comprehension as an essential skill and in using SRL to improve reading comprehension and achievement and enhance reading comprehension aids for language students and instructors.

Moreover, the results might encourage educators, administrators, and policymakers to capitalize on the effects of teaching SRL strategies by providing EFL teachers with preparation programs and experiences that help them improve their teaching methods and strategies, especially when teaching reading comprehension. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation" title="correlation">correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=reading%20proficiency" title=" reading proficiency"> reading proficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=self-regulated%20learning%20strategies" title=" self-regulated learning strategies"> self-regulated learning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=SRL" title=" SRL"> SRL</a>, <a href="https://publications.waset.org/abstracts/search?q=TOEIC%20reading%20comprehension" title=" TOEIC reading comprehension"> TOEIC reading comprehension</a> </p> <a href="https://publications.waset.org/abstracts/160434/the-correlation-between-self-regulated-learning-strategies-and-reading-proficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160434.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">95</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">258</span> Creating Database and Building 3D Geological Models: A Case Study on Bac Ai Pumped Storage Hydropower Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Chi%20Quang">Nguyen Chi Quang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Duong%20Tri%20Nguyen"> Nguyen Duong Tri Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article is the first step to research and outline the structure of the geotechnical database in the geological survey of a power project; in the context of this report creating the database that has been carried out for the Bac Ai pumped storage hydropower project. For the purpose of providing a method of organizing and storing geological and topographic survey data and experimental results in a spatial database, the RockWorks software is used to bring optimal efficiency in the process of exploiting, using, and analyzing data in service of the design work in the power engineering consulting. Three-dimensional (3D) geotechnical models are created from the survey data: such as stratigraphy, lithology, porosity, etc. The results of the 3D geotechnical model in the case of Bac Ai pumped storage hydropower project include six closely stacked stratigraphic formations by Horizons method, whereas modeling of engineering geological parameters is performed by geostatistical methods. The accuracy and reliability assessments are tested through error statistics, empirical evaluation, and expert methods. The three-dimensional model analysis allows better visualization of volumetric calculations, excavation and backfilling of the lake area, tunneling of power pipelines, and calculation of on-site construction material reserves. In general, the application of engineering geological modeling makes the design work more intuitive and comprehensive, helping construction designers better identify and offer the most optimal design solutions for the project. The database always ensures the update and synchronization, as well as enables 3D modeling of geological and topographic data to integrate with the designed data according to the building information modeling. This is also the base platform for BIM & GIS integration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=database" title="database">database</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20geology" title=" engineering geology"> engineering geology</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20Model" title=" 3D Model"> 3D Model</a>, <a href="https://publications.waset.org/abstracts/search?q=RockWorks" title=" RockWorks"> RockWorks</a>, <a href="https://publications.waset.org/abstracts/search?q=Bac%20Ai%20pumped%20storage%20hydropower%20project" title=" Bac Ai pumped storage hydropower project"> Bac Ai pumped storage hydropower project</a> </p> <a href="https://publications.waset.org/abstracts/150190/creating-database-and-building-3d-geological-models-a-case-study-on-bac-ai-pumped-storage-hydropower-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150190.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">168</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">257</span> Detect Cable Force of Cable Stayed Bridge from Accelerometer Data of SHM as Real Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Lan">Nguyen Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Tan%20Kien"> Le Tan Kien</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Pham%20Gia%20Bao"> Nguyen Pham Gia Bao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cable-stayed bridge belongs to the combined system, in which the cables is a major strutual element. Cable-stayed bridges with large spans are often arranged with structural health monitoring systems to collect data for bridge health diagnosis. Cables tension monitoring is a structural monitoring content. It is common to measure cable tension by a direct force sensor or cable vibration accelerometer sensor, thereby inferring the indirect cable tension through the cable vibration frequency. To translate cable-stayed vibration acceleration data to real-time tension requires some necessary calculations and programming. This paper introduces the algorithm, labview program that converts cable-stayed vibration acceleration data to real-time tension. The research results are applied to the monitoring system of Tran Thi Ly cable-stayed bridge and Song Hieu cable-stayed bridge in Vietnam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cable-stayed%20bridge" title="cable-stayed bridge">cable-stayed bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20fore" title=" cable fore"> cable fore</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20heath%20monitoring%20%28SHM%29" title=" structural heath monitoring (SHM)"> structural heath monitoring (SHM)</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20fourie%20transformed%20%28FFT%29" title=" fast fourie transformed (FFT)"> fast fourie transformed (FFT)</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time" title=" real time"> real time</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrations" title=" vibrations"> vibrations</a> </p> <a href="https://publications.waset.org/abstracts/182663/detect-cable-force-of-cable-stayed-bridge-from-accelerometer-data-of-shm-as-real-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182663.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">71</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">256</span> The Difficulties Encountered in Overseeing Learner-Centered Instructional Activities for Elementary School Children in Ho Chi Minh City, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Van%20Son%20Huynh">Van Son Huynh</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanh%20Huan%20Nguyen"> Thanh Huan Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tat%20Thien%20Do"> Tat Thien Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Thi%20Mai%20Thu%20Nguyen"> Thi Mai Thu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Thien%20Vu%20Giang"> Thien Vu Giang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given the necessity for substantial and all-encompassing educational reform, particularly in elementary Education, it is imperative to prioritize learner-centered instruction at the elementary level. This study focuses on the difficulties encountered in overseeing learner-centered instructional activities for elementary school children in Ho Chi Minh City (HCMC), the largest city in Vietnam in terms of population.
