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">611</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">287</span> Distribution and Taxonomy of Marine Fungi in Nha Trang Bay and Van Phong Bay, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thu%20Thuy%20Pham">Thu Thuy Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Thi%20Chau%20Loan%20Tran"> Thi Chau Loan Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Duy%20Nguyen"> Van Duy Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Marine fungi play an important role in the marine ecosystems. Marine fungi also supply biomass and metabolic products of industrial value. Currently, the biodiversity of marine fungi along the coastal areas of Vietnam has not yet been studied fully. The objective of this study is to assess the spatial and temporal diversity of planktonic fungi from the coastal waters of Nha Trang Bay and Van Phong Bay in Central Vietnam using culture-dependent and independent approach. Using culture-dependent approach, filamentous fungi and yeasts were isolated on selective media and then classified by phenotype and genotype based on the sequencing of ITS (internal transcribed spacers) regions of rDNA with two primer pairs (ITS1F_KYO2 and ITS4; NS1 and NS8). Using culture-independent approach, environmental DNA samples were isolated and amplified using fungal-specific ITS primer pairs. A total of over 160 strains were isolated from 10 seawater sampling stations at 50 cm depth. They were classified into diverse genera and species of both yeast and mold. At least 5 strains could be potentially novel species. Our results also revealed that planktonic fungi were molecularly diverse with hundreds of phylotypes recovered across these two bays. The results of the study provide data about the distribution and taxonomy of mycoplankton in this area, thereby allowing assessment of their positive role in the biogeochemical cycle of coastal ecosystems and the development of new bioactive compounds for industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=ITS" title=" ITS"> ITS</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20fungi" title=" marine fungi"> marine fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nha%20Trang%20Bay" title=" Nha Trang Bay"> Nha Trang Bay</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Phong%20Bay" title=" Van Phong Bay"> Van Phong Bay</a> </p> <a href="https://publications.waset.org/abstracts/85603/distribution-and-taxonomy-of-marine-fungi-in-nha-trang-bay-and-van-phong-bay-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85603.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">190</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">286</span> Generating Product Description with Generative Pre-Trained Transformer 2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minh-Thuan%20Nguyen">Minh-Thuan Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Phuong-Thai%20Nguyen"> Phuong-Thai Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Van-Vinh%20Nguyen"> Van-Vinh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Quang-Minh%20Nguyen"> Quang-Minh Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Research on automatically generating descriptions for e-commerce products is gaining increasing attention in recent years. 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">285</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.

Fifteen IDUs participated and two local interviewers conducted qualitative semi-structured face-to-face interviews in September-October, 2012 in Vietnamese language. Data were analyzed thematically. Non-protective condom attitudes include negotiate or convince Female Sex Workers (FSW); not realizing risk, importance or necessity; partner doesn’t like, and having extra money/drug from clients. On the other hand, self-awareness, family-consciousness, suspicion of STI presence, fear of getting HIV, and client negotiation sometimes resulted in a safe-sex practice. A thematic diagram was developed to present the relationship (strong/weak) between condom attitude and sexual practice (safe/unsafe) by partner types. The experiences and views reflected in the qualitative information emphasize the heightened need for safe-sex education especially among young IDUs (male/female) highlighting sexual transmission risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AIDS" title="AIDS">AIDS</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=injecting%20drug%20user" title=" injecting drug user"> injecting drug user</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20behaviors" title=" risk behaviors"> risk behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnam" title=" Vietnam "> Vietnam </a> </p> <a href="https://publications.waset.org/abstracts/4419/sexual-behaviors-and-condom-attitude-among-injecting-drug-users-in-hai-phong-vietnam-qualitative-findings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4419.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">857</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">283</span> Application of Fuzzy Logic to Design and Coordinate Parallel Behaviors for a Humanoid Mobile Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Chan%20Hung">Nguyen Chan Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ngoc%20Anh"> Mai Ngoc Anh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Xuan%20Ha"> Nguyen Xuan Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Xuan%20Duc"> Tran Xuan Duc</a>, <a href="https://publications.waset.org/abstracts/search?q=Dang%20Bao%20Lam"> Dang Bao Lam</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Hoang%20Viet"> Nguyen Hoang Viet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a design and implementation of a navigation controller for a humanoid mobile robot platform to operate in indoor office environments.

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> Payments for Forest Environmental Services: Advantages and Disadvantages in the Different Mechanisms in Vietnam North Central Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huong%20Nguyen%20Thi%20Thanh">Huong Nguyen Thi Thanh</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Mai%20Thi%20Khanh"> Van Mai Thi Khanh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For around the world, payments for environmental services have been implemented since the late 1970s in Europe and North America; then, it was spread to Latin America, Asia, Africa, and finally Oceania in 2008. In Vietnam, payments for environmental services are an interesting issue recently with the forest as the main focus and therefore known as the program on payment for forest environmental services (PFES). PFES was piloted in Lam Dong and Son La in 2008 and has been widely applied in many provinces after 2010. PFES is in the orientation for the socialization of national forest protection in Vietnam and has made great strides in the last decade. By using the primary data and secondary data simultaneously, the paper clarifies two cases of implementing PFES in the Vietnam North Central area with the different mechanisms of payment. In the first case at Phu Loc district (Thua Thien Hue province), PFES is an indirect method by a water supply company via the Forest Protection and Development Fund. In the second one at Phong Nha – Ke Bang National Park (Quang Binh Province), tourism companies are the direct payers to forest owners. The paper describes the PFES implementation process at each site, clarifies the payment mechanism, and models the relationship between stakeholders in PFES implementation. Based on the current status of PFES sites, the paper compares and analyzes the advantages and disadvantages of the two payment methods.

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 results of the case study are demonstrated and discussed which would provide the processing of actions helped decision makers to choose flood risk reduction investment options. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drainage%20plan" title="drainage plan">drainage plan</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20planning" title=" flood planning"> flood planning</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20risk" title=" flood risk"> flood risk</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20risk" title=" residual risk"> residual risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20optimization" title=" risk optimization"> risk optimization</a> </p> <a href="https://publications.waset.org/abstracts/87574/flood-planning-based-on-risk-optimization-a-case-study-in-phan-calo-river-basin-in-vinh-phuc-province-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87574.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">242</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">273</span> Enhancing the Stability of Vietnamese Power System - from Theory to Practical</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Lerch">Edwin Lerch</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirk%20Audring"> Dirk Audring</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuong%20Nguyen%20Mau"> Cuong Nguyen Mau</a>, <a href="https://publications.waset.org/abstracts/search?q=Duc%20Ninh%20Nguyen"> Duc Ninh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Cuong%20Nguyen"> The Cuong Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Van%20Nguyen"> The Van Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The National Load Dispatch Centre of Electricity Vietnam (EVNNLDC) and Siemens PTI investigated the stability of the electrical 500/220 kV transportation system of Vietnam. 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">360</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.

The simulation results have shown that both CGA and PSO can be used in the distribution network reconfiguration and CGA outperformed PSO with significant success rate in finding optimal distribution network configuration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distribution%20network%20reconfiguration" title="distribution network reconfiguration">distribution network reconfiguration</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20genetic%20algorithm" title=" continuous genetic algorithm"> continuous genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20loss%20reduction" title=" power loss reduction"> power loss reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20deviation" title=" voltage deviation"> voltage deviation</a> </p> <a href="https://publications.waset.org/abstracts/101407/comparison-between-continuous-genetic-algorithms-and-particle-swarm-optimization-for-distribution-network-reconfiguration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101407.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">187</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">271</span> Efficient Heuristic Algorithm to Speed Up Graphcut in Gpu for Image Stitching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tai%20Nguyen">Tai Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Minh%20Bui"> Minh Bui</a>, <a href="https://publications.waset.org/abstracts/search?q=Huong%20Ninh"> Huong Ninh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%20Nguyen"> Tu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hai%20Tran"> Hai Tran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> GraphCut algorithm has been widely utilized to solve various types of computer vision problems. 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. However, the problem of low convergence speed prevents the usage of GraphCut for real time applications. 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.

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.

Phan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wilson’s disease (WD) is an autosomal recessive disorder of the copper metabolism, which is caused by a mutation in the copper-transporting P-type ATPase (<em>ATP7B</em>). 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> 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. The quality standards and characteristics of missile operations are very strict, requiring high stability and accurate response to commands within a relatively wide range of work. The study analyzes the linear transfer function model of the Missile Roll channel to facilitate the development of control systems. 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 study uses MATLAB simulation software to implement the genetic algorithm and evaluate the quality of the closed-loop system. The results show that the system achieves better quality than the original structure and is simple, reliable, and ready for implementation in practical experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=roll%20chanel" title=" roll chanel"> roll chanel</a>, <a href="https://publications.waset.org/abstracts/search?q=two-loop%20control%20structure" title=" two-loop control structure"> two-loop control structure</a>, <a href="https://publications.waset.org/abstracts/search?q=missile" title=" missile"> missile</a> </p> <a href="https://publications.waset.org/abstracts/164639/optimized-control-of-roll-stability-of-missile-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164639.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">261</span> An Investigation on Designing and Enhancing the Performance of H-Darrieus Wind Turbine of 10KW at the Medium Range of Wind Speed in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ich%20Long%20Ngo">Ich Long Ngo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinh%20Tai%20Dang"> Dinh Tai Dang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ngoc%20Tu%20Nguyen"> Ngoc Tu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Minh%20Duc%20Nguyen"> Minh Duc Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes an investigation on designing and enhancing the performance of H-Darrieus wind turbine (HDWT) of 10kW at the medium wind speed. 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">260</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. The analysis from TOEIC reading tests with SPSS 25.0 indicated that there are substantial differences between the post-test reading scores between the experimental group and the control group; therefore, SRL impacts the reading comprehension of EFL participants. 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. They should equip educators with a variety of instructional strategies which assist academics in preparing learners for lifetime language study and independence. 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">259</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"
