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">286</span> Information Technology and Communications in Management of the Imperial Citadel of Thang Long-A World Heritage Site</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ngo%20the%20Bach">Ngo the Bach</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information technology and communications are growing strongly and penetrated almost the entire Vietnamese economy and society.

Considering that EEG signals are nonstationary and often contaminated by various types of artifacts, classifying thoughts into correct mental states is not a trivial problem. In this work, our contribution is that we present and realize a novel model which integrates different techniques: Independent component analysis (ICA), relative wavelet energy, and support vector machine (SVM) for the same task. We applied our model to classify thoughts in two types of experiment whether with two or three mental states.

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.

However, this algorithm is not robust in cases where the object is lost by a sudden change of direction, being obscured or going out of view. In order to improve KCF performance in long-term tracking, this paper proposes an anomaly detection method for target loss warning by analyzing the response map of each frame, and a classification algorithm for reliable target re-locating mechanism by using Random fern. Being tested with Visual Tracker Benchmark and Visual Object Tracking datasets, the experimental results indicated that the precision and success rate of the proposed algorithm were 2.92 and 2.61 times higher than that of the original KCF algorithm, respectively. Moreover, the proposed tracker handles occlusion better than many state-of-the-art long-term tracking methods while running at 60 frames per second. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation%20filter" title="correlation filter">correlation filter</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20tracking" title=" long-term tracking"> long-term tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20fern" title=" random fern"> random fern</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20tracking" title=" real-time tracking"> real-time tracking</a> </p> <a href="https://publications.waset.org/abstracts/130580/fast-and-robust-long-term-tracking-with-effective-searching-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130580.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">137</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">282</span> Study on Discontinuity Properties of Phased-Array Ultrasound Transducer Affecting to Sound Pressure Fields Pattern</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tran%20Trong%20Thang">Tran Trong Thang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Phan%20Kien"> Nguyen Phan Kien</a>, <a href="https://publications.waset.org/abstracts/search?q=Trinh%20Quang%20Duc"> Trinh Quang Duc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The phased-array ultrasound transducer types are utilities for medical ultrasonography as well as optical imaging.

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">278</span> The Impact of Brand-Related User-Generated Content on Brand Positioning: A Study on Private Higher Education Institutes in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charitha%20Harshani%20Perera">Charitha Harshani Perera</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajkishore%20%20Nayak"> Rajkishore Nayak</a>, <a href="https://publications.waset.org/abstracts/search?q=Long%20Thang%20Van%20Nguyen"> Long Thang Van Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the advent of social media, Vietnam has changed the way customers perceive the information about the brand. In the context of higher education, the adoption of social media has received attention with the increasing rate of social media usage among undergraduates. Brand-related user-generated content (UGC) on social media emphasizes the social ties between users and users’ participation, which promotes the communication to build and maintain the relationship with the brands. Although brand positioning offers a significant competitive advantage, the association with brand-related user-generated content in social media with brand positioning in the context of higher education is still an under-researched area. Accordingly, using social identity theory and social exchange theory, this research aims to deepen our understanding of the influence of brand-related user-generated content on brand positioning and purchase intention. Employing a quantitative survey design,384 Vietnamese undergraduates were selected based on purposive sampling. The findings suggest that brand-related user-generated content influence brand positioning and brand choice intention. However, there is a significant mediating effect of the reliability and understandability of the content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brand%20positioning" title="brand positioning">brand positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=brand-related%20user-generated%20content" title=" brand-related user-generated content"> brand-related user-generated content</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20countries" title=" emerging countries"> emerging countries</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education "> higher education </a> </p> <a href="https://publications.waset.org/abstracts/113688/the-impact-of-brand-related-user-generated-content-on-brand-positioning-a-study-on-private-higher-education-institutes-in-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113688.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">177</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">277</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.

A contra-rotating centrifugal compressor (CRCC) is constructed using two independent rotors, rotating in the opposite direction and replacing the single rotor of a conventional centrifugal compressor (REF). To respect the geometrical parameters of the REF one, two rotors of the CRCC are designed, based on a single rotor geometry, using the hub and shroud length ratio parameter of the meridional contour. Firstly, the first rotor is designed by choosing a value of length ratio. Then, the second rotor is calculated to be adapted to the fluid flow of the first rotor according aerodynamics principles. In this study, four values of length ratios 0.3, 0.4, 0.5, and 0.6 are used to create four configurations CF1, CF2, CF3, and CF4 respectively. For comparison purpose, the circumferential velocity at the outlet of the REF and the CRCC are preserved, which means that the single rotor of the REF and the second rotor of the CRCC rotate with the same speed of 16000rpm. The speed of the first rotor in this case is chosen to be equal to the speed of the second rotor. The CFD simulation is conducted to compare the performance of the CRCC and the REF with the same boundary conditions. The results show that the configuration with a higher length ratio gives higher pressure rise. However, its efficiency is lower. An investigation over the entire operating range shows that the CF1 is the best configuration in this case. In addition, the CRCC can improve the pressure rise as well as the efficiency by changing the speed of each rotor independently. The results of changing the first rotor speed show with a 130% speed increase, the pressure ratio rises of 8.7% while the efficiency remains stable at the flow rate of the design operating point. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centrifugal%20compressor" title="centrifugal compressor">centrifugal compressor</a>, <a href="https://publications.waset.org/abstracts/search?q=contra-rotating" title=" contra-rotating"> contra-rotating</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20rotor" title=" interaction rotor"> interaction rotor</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum" title=" vacuum"> vacuum</a> </p> <a href="https://publications.waset.org/abstracts/105648/study-of-the-effect-of-the-contra-rotating-component-on-the-performance-of-the-centrifugal-compressor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105648.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">134</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">275</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">85</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> 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.

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">270</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">269</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">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">268</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. 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 film condensation model based on mass transfer was used to solve phase change. On the floor, condensation rate was obtained by mass fraction change near the floor. The study investigated effects of inlet velocity, inlet relative humidity and cold floor temperature on the condensation rate. The simulations were done in both 2D and 3D models to show the difference and need for 3D modeling of condensation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20and%20mass%20transfer" title="heat and mass transfer">heat and mass transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=convection" title=" convection"> convection</a>, <a href="https://publications.waset.org/abstracts/search?q=condensation" title=" condensation"> condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=user-defined%20functions" title=" user-defined functions"> user-defined functions</a> </p> <a href="https://publications.waset.org/abstracts/71123/numeric-modeling-of-condensation-of-water-vapor-from-humid-air-in-a-room" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71123.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">331</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> Using Priority Order of Basic Features for Circumscribed Masses Detection in Mammograms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minh%20Dong%20Le">Minh Dong Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Viet%20Dung%20Nguyen"> Viet Dung Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Huu%20Viet"> Do Huu Viet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Huu%20Tu"> Nguyen Huu Tu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a new method for circumscribed masses detection in mammograms.

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">261</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.

The plant samples for our experiment were collected from Lam Dong province, Vietnam. Seven suspension solutions of nanosized zinc hydroxide nitrate (Zn<sub>5</sub>(OH)<sub>8</sub>(NO<sub>3</sub>)<sub>2</sub>·2H<sub>2</sub>O) with different Zn concentration were used. Fertilization and irrigation were the same for all variants. The Zn content and the content of selected micro (Cu, Fe, Mn) and macro (Ca, Mg, P and K) nutrients in plant roots, and stems and leaves were determined. It was concluded that the zinc content of plant roots varies narrowly, with no significant impact of ZnHN fertilization. The same trend can be seen in the content of Cu, Mn, and macronutrients. The zinc content of plant stems and leaves varies within wide limits, with the significant impact of ZnHN fertilization. The trends in the content of Cu, Mn, and macronutrients are kept the same as in the root, whereas the iron trends to increase its content at increasing the zinc content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phyllanthus%20amarus" title="Phyllanthus amarus">Phyllanthus amarus</a>, <a href="https://publications.waset.org/abstracts/search?q=Zinc" title=" Zinc"> Zinc</a>, <a href="https://publications.waset.org/abstracts/search?q=Micro%20and%20macro%20elements" title=" Micro and macro elements"> Micro and macro elements</a>, <a href="https://publications.waset.org/abstracts/search?q=foliar%20fertilizer" title=" foliar fertilizer"> foliar fertilizer</a> </p> <a href="https://publications.waset.org/abstracts/106560/impact-of-foliar-application-of-zinc-on-micro-and-macro-elements-distribution-in-phyllanthus-amarus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106560.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">151</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> Numerical Modeling Analysis for the Double-Layered Asphalt Pavement Structure Behavior with Interface Bonding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minh%20Tu%20Le">Minh Tu Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Quang%20Huy%20Nguyen"> Quang Huy Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mai%20Lan%20Nguyen"> Mai Lan Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bonding characteristics between pavement layers have an important influence on responses of pavement structures. 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
