The specific surface area of Cu-nano zeolite was measured as 869.32 m2/g with a pore size of 3.86 nm. The adsorption capacity of CO2 by Cu-nano zeolite was decreased with increasing temperature. The identified adsorption capacity of CO2 by Cu-nano zeolite was 7.16 mmol/g at a temperature of 20 oC and at pressure of 1 atm. The adoption selectivity of CO2 over N2 strongly depend on the temperature and the highest selectivity by Cu-nano zeolite was 50.71 at 20 oC. From analysis of regeneration characteristics of CO2 loaded adsorbent, the percentage removal of CO2 was maintained at more than 78.2 % even after 10 cycles of adsorption-desorption.

However, direct short-pulse generation is not as straight forward in solid-state gain media as it is for near-IR tunable solid-state lasers such as Ti:sapphire due to the difficulty of obtaining continuous wave laser operation, which is required for Kerr lens mode-locking schemes utilizing spatial or temporal Kerr type nonlinearity. In this work, the transient cavity method, which was reported to generate ultrashort laser pulses in dye lasers, is extended to a solid-state gain medium. Ce:LiCAF was chosen among the rare-earth-doped fluoride laser crystals emitting in the UV region because of its broad tunability (from 280 to 325 nm) and enough bandwidth to generate 3-fs pulses, sufficiently large effective gain cross section (6.0 x10⁻¹⁸ cm²) favorable for oscillators, and a high saturation fluence (115 mJ/cm²). Numerical simulations are performed to investigate the spectro-temporal evolution of the broadband UV laser emission from Ce:LiCAF, represented as a system of two homogeneous broadened singlet states, by solving the rate equations extended to multiple wavelengths. The goal is to find the appropriate cavity length and Q-factor to achieve the optimal photon cavity decay time and pumping energy for resonator transients that will lead to ps UV laser emission from a Ce:LiCAF crystal pumped by the fourth harmonics (266nm) of a Nd:YAG laser. Results show that a single ps pulse can be generated from a 1-mm, 1 mol% Ce³⁺-doped LiCAF crystal using an output coupler with 10% reflectivity (low-Q) and an oscillator cavity that is 2-mm long (short cavity). This technique can be extended to other fluoride-based solid-state laser gain media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rare-earth-doped%20fluoride%20gain%20medium" title="rare-earth-doped fluoride gain medium">rare-earth-doped fluoride gain medium</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20cavity" title=" transient cavity"> transient cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrashort%20laser" title=" ultrashort laser"> ultrashort laser</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20laser" title=" ultraviolet laser"> ultraviolet laser</a> </p> <a href="https://publications.waset.org/abstracts/71437/proposed-design-of-an-optimized-transient-cavity-picosecond-ultraviolet-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71437.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">357</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">59</span> Microwave Plasma Dry Reforming of Methane at High CO2/CH4 Feed Ratio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Majd%20Alawi">Nabil Majd Alawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gia%20Hung%20Pham"> Gia Hung Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Barifcani"> Ahmed Barifcani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dry reforming of methane that converts two greenhouses gases (CH<sub>4</sub> and CO<sub>2</sub>) to synthesis gas (a mixture of H<sub>2</sub> and CO) was studied in a commercial bench scale microwave (MW) plasma reactor system at atmospheric pressure.

Tree in paddy fields in the northeast of Thailand is one of those traditional landscapes. Using three different historical time layers, we acknowledged the severe deforestation and rapid urbanization happened in the region. Despite the general thinking of decline in tree density as consequences, the heterogeneous trend of changes in total tree density in three studied landscapes denied the hypothesis that number of trees in paddy field depend on the length of land use practice. On the other hand, due to selection of planting new trees on levees, existence of trees in paddy field are now rely on their values for human use. Besides, changes in land use and landscape structure had a significant impact on decision of which tree density level is considered as suitable for the landscape. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20photographs" title="aerial photographs">aerial photographs</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20change" title=" land use change"> land use change</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20landscape" title=" traditional landscape"> traditional landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=tree%20in%20paddy%20fields" title=" tree in paddy fields"> tree in paddy fields</a> </p> <a href="https://publications.waset.org/abstracts/15536/historical-landscape-affects-present-tree-density-in-paddy-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15536.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">419</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">56</span> Model of Optimal Centroids Approach for Multivariate Data Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pham%20Van%20Nha">Pham Van Nha</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Cam%20Binh"> Le Cam Binh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Particle swarm optimization (PSO) is a population-based stochastic optimization algorithm. PSO was inspired by the natural behavior of birds and fish in migration and foraging for food. PSO is considered as a multidisciplinary optimization model that can be applied in various optimization problems. PSO’s ideas are simple and easy to understand but PSO is only applied in simple model problems. We think that in order to expand the applicability of PSO in complex problems, PSO should be described more explicitly in the form of a mathematical model. In this paper, we represent PSO in a mathematical model and apply in the multivariate data classification. First, PSOs general mathematical model (MPSO) is analyzed as a universal optimization model. Then, Model of Optimal Centroids (MOC) is proposed for the multivariate data classification. Experiments were conducted on some benchmark data sets to prove the effectiveness of MOC compared with several proposed schemes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analysis%20of%20optimization" title="analysis of optimization">analysis of optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence%20based%20optimization" title=" artificial intelligence based optimization"> artificial intelligence based optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20for%20learning%20and%20data%20analysis" title=" optimization for learning and data analysis"> optimization for learning and data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20optimization" title=" global optimization"> global optimization</a> </p> <a href="https://publications.waset.org/abstracts/126058/model-of-optimal-centroids-approach-for-multivariate-data-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126058.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">208</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">55</span> Genetic Algorithm and Multi-Parametric Programming Based Cascade Control System for Unmanned Aerial Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dao%20Phuong%20Nam">Dao Phuong Nam</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Trong%20Tan"> Do Trong Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Pham%20Tam%20Thanh"> Pham Tam Thanh</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Duy%20Tung"> Le Duy Tung</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Hoang%20Anh"> Tran Hoang Anh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers the problem of cascade control system for unmanned aerial vehicles (UAVs).

Simulation results are presented to show that the equivalent path has been found and obtained by proposed cascade control scheme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=GA" title=" GA"> GA</a>, <a href="https://publications.waset.org/abstracts/search?q=H%20infinity" title=" H infinity"> H infinity</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-parametric%20programming" title=" multi-parametric programming"> multi-parametric programming</a>, <a href="https://publications.waset.org/abstracts/search?q=MPP" title=" MPP"> MPP</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicles" title=" unmanned aerial vehicles"> unmanned aerial vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=UAVs" title=" UAVs"> UAVs</a> </p> <a href="https://publications.waset.org/abstracts/81434/genetic-algorithm-and-multi-parametric-programming-based-cascade-control-system-for-unmanned-aerial-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81434.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">212</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">54</span> Combination Approach Using Experiments and Optimal Experimental Design to Optimize Chemical Concentration in Alkali-Surfactant-Polymer Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Tai%20Pham">H.

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">90</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">50</span> Detect Cable Force of Cable Stayed Bridge from Accelerometer Data of SHM as Real Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Lan">Nguyen Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Tan%20Kien"> Le Tan Kien</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Pham%20Gia%20Bao"> Nguyen Pham Gia Bao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cable-stayed bridge belongs to the combined system, in which the cables is a major strutual element.

Cables tension monitoring is a structural monitoring content. It is common to measure cable tension by a direct force sensor or cable vibration accelerometer sensor, thereby inferring the indirect cable tension through the cable vibration frequency. To translate cable-stayed vibration acceleration data to real-time tension requires some necessary calculations and programming.

To ensure that the activities of the state in the fields of politics, economy and society has been efficiency, it requires major sources of certain budget. These financial funds are formed from tax revenues and tax revenues beyond. Therefore, the Governments need to have an accounting regime to manage the receipt, expenditure which are suitable for recording a full range of items. From that, it can help to increase the transparency and accountability in budget system. One of the main requirements in Vietnamese policies is to improve that accounting system of revenues and expenditures which can provide many reports to meet the information required of government and users, as well as directions to the trends of international standards requirements. By using quantitative research methods and analytical models to exploring factors, the main purpose of this article is to identify the factors affecting budget accounting and providing some direction for Vietnamese public sector in the future. The results indicated that Vietnam budget accounting has been impacted by seven factors and aims to implement three main orientations in the public sector units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=state%20budget" title="state budget">state budget</a>, <a href="https://publications.waset.org/abstracts/search?q=accounting" title=" accounting"> accounting</a>, <a href="https://publications.waset.org/abstracts/search?q=IPSAS" title=" IPSAS"> IPSAS</a>, <a href="https://publications.waset.org/abstracts/search?q=budget%20management" title=" budget management"> budget management</a>, <a href="https://publications.waset.org/abstracts/search?q=government" title=" government"> government</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sector" title=" public sector"> public sector</a> </p> <a href="https://publications.waset.org/abstracts/11493/state-budget-accounting-factors-affected-and-basic-orientation-to-vietnamese-public-sector-entities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11493.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">270</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">46</span> Motor Controller Implementation Using Model Based Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cau%20Tran">Cau Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%20Nguyen"> Tu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tien%20Pham"> Tien Pham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Model-based design (MBD) is a mathematical and visual technique for addressing design issues in the fields of communications, signal processing, and complicated control systems. It is utilized in several automotive, aerospace, industrial, and motion control applications. Virtual models are at the center of the software development process with model based design. A method used in the creation of embedded software is model-based design. In this study, the LAT motor is modeled in a simulation environment, and the LAT motor control is designed with a cascade structure, a speed and current control loop, and a controller that is used in the next part. A PID structure serves as this controller. Based on techniques and motor parameters that match the design goals, the PID controller is created for the model using traditional design principles. The MBD approach will be used to build embedded software for motor control. The paper will be divided into three distinct sections. The first section will introduce the design process and the benefits and drawbacks of the MBD technique. The design of control software for LAT motors will be the main topic of the next section. The experiment's results are the subject of the last section. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=model%20based%20design" title="model based design">model based design</a>, <a href="https://publications.waset.org/abstracts/search?q=limited%20angle%20torque" title=" limited angle torque"> limited angle torque</a>, <a href="https://publications.waset.org/abstracts/search?q=intellectual%20property%20core" title=" intellectual property core"> intellectual property core</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware%20description%20language" title=" hardware description language"> hardware description language</a>, <a href="https://publications.waset.org/abstracts/search?q=controller%20area%20network" title=" controller area network"> controller area network</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20datagram%20protocol" title=" user datagram protocol"> user datagram protocol</a> </p> <a href="https://publications.waset.org/abstracts/159211/motor-controller-implementation-using-model-based-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159211.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">94</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">45</span> A Unified Deep Framework for Joint 3d Pose Estimation and Action Recognition from a Single Color Camera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huy%20Hieu%20Pham">Huy Hieu Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Houssam%20Salmane"> Houssam Salmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Louahdi%20Khoudour"> Louahdi Khoudour</a>, <a href="https://publications.waset.org/abstracts/search?q=Alain%20Crouzil"> Alain Crouzil</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Zegers"> Pablo Zegers</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Velastin"> Sergio Velastin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a deep learning-based multitask framework for joint 3D human pose estimation and action recognition from color video sequences. Our approach proceeds along two stages. In the first, we run a real-time 2D pose detector to determine the precise pixel location of important key points of the body. A two-stream neural network is then designed and trained to map detected 2D keypoints into 3D poses. In the second, we deploy the Efficient Neural Architecture Search (ENAS) algorithm to find an optimal network architecture that is used for modeling the Spatio-temporal evolution of the estimated 3D poses via an image-based intermediate representation and performing action recognition. Experiments on Human3.6M, Microsoft Research Redmond (MSR) Action3D, and Stony Brook University (SBU) Kinect Interaction datasets verify the effectiveness of the proposed method on the targeted tasks.

The development of map generalization research accompanied the development of cartography. The traditional map is plotted manually by cartographic experts. The paper studies none-scale automation generalization of resident polygons and house marker symbol, proposes methodology to evaluate the result maps based on minimal spanning tree. In this paper, the minimal spanning tree before and after map generalization is compared to evaluate whether the generalization result maintain the geographical distribution of features. The minimal spanning tree in vector format is firstly converted into a raster format and the grid size is 2mm (distance on the map). The statistical number of matching grid before and after map generalization and the ratio of overlapping grid to the total grids is calculated. Evaluation experiments are conduct to verify the results.

Those factors include company size, profitability, leverage, state ownership, managerial ownership, and foreign ownership, board independence, role duality and type of external auditors. Evidence from this study suggests two main findings. (1) Companies with high foreign ownership have a high level of voluntary disclosure. (2) The company size is an important factor related to the increased level of voluntary disclosure in annual reports made by Vietnamese listed companies. The larger the company, the higher the information is disclosed. However, no significant associations are found between profitability, leverage, state ownership, managerial ownership, board independence, role duality and type of external auditors as hypothesized in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=voluntary%20disclosure" title="voluntary disclosure">voluntary disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnamese%20listed%20companies" title=" Vietnamese listed companies"> Vietnamese listed companies</a>, <a href="https://publications.waset.org/abstracts/search?q=voluntary" title=" voluntary"> voluntary</a>, <a href="https://publications.waset.org/abstracts/search?q=duality" title=" duality"> duality</a> </p> <a href="https://publications.waset.org/abstracts/25265/factors-influencing-the-voluntary-disclosure-of-vietnamese-listed-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25265.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">410</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">42</span> Content Based Video Retrieval System Using Principal Object Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Van%20Thinh%20Bui">Van Thinh Bui</a>, <a href="https://publications.waset.org/abstracts/search?q=Anh%20Tuan%20Tran"> Anh Tuan Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Quoc%20Viet%20Ngo"> Quoc Viet Ngo</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Bao%20Pham"> The Bao Pham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Video retrieval is a searching problem on videos or clips based on content in which they are relatively close to an input image or video. The application of this retrieval consists of selecting video in a folder or recognizing a human in security camera. However, some recent approaches have been in challenging problem due to the diversity of video types, frame transitions and camera positions. Besides, that an appropriate measures is selected for the problem is a question. In order to overcome all obstacles, we propose a content-based video retrieval system in some main steps resulting in a good performance. From a main video, we process extracting keyframes and principal objects using Segmentation of Aggregating Superpixels (SAS) algorithm. After that, Speeded Up Robust Features (SURF) are selected from those principal objects. Then, the model “Bag-of-words” in accompanied by SVM classification are applied to obtain the retrieval result. Our system is performed on over 300 videos in diversity from music, history, movie, sports, and natural scene to TV program show. The performance is evaluated in promising comparison to the other approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=video%20retrieval" title="video retrieval">video retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20objects" title=" principal objects"> principal objects</a>, <a href="https://publications.waset.org/abstracts/search?q=keyframe" title=" keyframe"> keyframe</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation%20of%20aggregating%20superpixels" title=" segmentation of aggregating superpixels"> segmentation of aggregating superpixels</a>, <a href="https://publications.waset.org/abstracts/search?q=speeded%20up%20robust%20features" title=" speeded up robust features"> speeded up robust features</a>, <a href="https://publications.waset.org/abstracts/search?q=bag-of-words" title=" bag-of-words"> bag-of-words</a>, <a href="https://publications.waset.org/abstracts/search?q=SVM" title=" SVM"> SVM</a> </p> <a href="https://publications.waset.org/abstracts/59753/content-based-video-retrieval-system-using-principal-object-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59753.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">301</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">41</span> Explainable Graph Attention Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Pham">David Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongfeng%20Zhang"> Yongfeng Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Graphs are an important structure for data storage and computation. Recent years have seen the success of deep learning on graphs such as Graph Neural Networks (GNN) on various data mining and machine learning tasks. However, most of the deep learning models on graphs cannot easily explain their predictions and are thus often labelled as “black boxes.” For example, Graph Attention Network (GAT) is a frequently used GNN architecture, which adopts an attention mechanism to carefully select the neighborhood nodes for message passing and aggregation. However, it is difficult to explain why certain neighbors are selected while others are not and how the selected neighbors contribute to the final classification result. In this paper, we present a graph learning model called Explainable Graph Attention Network (XGAT), which integrates graph attention modeling and explainability. We use a single model to target both the accuracy and explainability of problem spaces and show that in the context of graph attention modeling, we can design a unified neighborhood selection strategy that selects appropriate neighbor nodes for both better accuracy and enhanced explainability. To justify this, we conduct extensive experiments to better understand the behavior of our model under different conditions and show an increase in both accuracy and explainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=explainable%20AI" title="explainable AI">explainable AI</a>, <a href="https://publications.waset.org/abstracts/search?q=graph%20attention%20network" title=" graph attention network"> graph attention network</a>, <a href="https://publications.waset.org/abstracts/search?q=graph%20neural%20network" title=" graph neural network"> graph neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=node%20classification" title=" node classification"> node classification</a> </p> <a href="https://publications.waset.org/abstracts/156796/explainable-graph-attention-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156796.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">198</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">40</span> Understanding Health-Related Properties of Grapes by Pharmacokinetic Modelling of Intestinal Absorption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sophie%20N.%20Selby-Pham">Sophie N.

The bioefficacy of phytochemicals depends on their absorption in the human body. The time required for phytochemicals to achieve maximal plasma concentration (Tₘₐₓ) after oral intake reflects the time window of maximal bioefficacy of phytochemicals, with Tₘₐₓ dependent on physicochemical properties of phytochemicals. This research collated physicochemical properties of grape phytochemicals from white and red grapes to predict their Tₘₐₓ using pharmacokinetic modelling. The predicted values of Tₘₐₓ were then compared to the measured Tₘₐₓ collected from clinical studies to determine the accuracy of prediction. In both liquid and solid intake forms, white grapes exhibit a shorter Tₘₐₓ range (0.5-2.5 h) versus red grapes (1.5-5h). The prediction accuracy of Tₘₐₓ for grape phytochemicals was 33.3% total error of prediction compared to the mean, indicating high prediction accuracy. Pharmacokinetic modelling allows prediction of Tₘₐₓ without costly clinical trials, informing dosing frequency for sustained presence of phytochemicals in the body to optimize the health benefits of phytochemicals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption%20kinetics" title="absorption kinetics">absorption kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical%20absorption%20prediction%20model" title=" phytochemical absorption prediction model"> phytochemical absorption prediction model</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitis%20vinifera" title=" Vitis vinifera"> Vitis vinifera</a> </p> <a href="https://publications.waset.org/abstracts/95074/understanding-health-related-properties-of-grapes-by-pharmacokinetic-modelling-of-intestinal-absorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95074.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">148</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">39</span> Sustainable Use of Fresh Groundwater Lens of Pleistocene Aquifer in Nam Dinh, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tran%20Thanh%20Le">Tran Thanh Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Pham%20Trong%20Duc"> Pham Trong Duc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fresh groundwater lens of the Pleistocene aquifer in Nam Dinh was formed since 12,900 years ago. Currently, the Pleistocene aquifer has been continuously exploited on average of 154,163m3/day, distributed mainly in the districts of Nghia Hung, Hai Hau, a part of Truc Ninh, Y Yen, Nam Truc and Giao Thuy. The groundwater level is still on a declining trend, saltwater intrusion in this freshwater lens can occur if the growth rate in exploitation is maintained. This study focused on groundwater sustainable use by means of 4 groups of criteria including: Groundwater quality and pollution; Aquifers’ productivity and capacity; Environment impacts due to exploitation (groundwater level decline, land subsidence due to water exploitation); Social and economic impacts. Using a combination of methods including field surveys, geophysics, hydrogeochemistry, isotope and numerical models to determine safe groundwater exploitation thresholds for the whole study area has been determined to be 544,314m3/day and the actual exploitation amount is currently about 30% compared to the safe exploitation threshold. However, it should also be noted that the current groundwater exploitation threshold and level of its exploitation compared to the safe exploitation threshold of each locality are not the same. From this result, the groundwater exploitation threshold map of the study area was established to serve the management, licensing and orientation of groundwater exploitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criteria" title="criteria">criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20groundwater%20lens" title=" fresh groundwater lens"> fresh groundwater lens</a>, <a href="https://publications.waset.org/abstracts/search?q=pleistocene" title=" pleistocene"> pleistocene</a>, <a href="https://publications.waset.org/abstracts/search?q=Nam%20Dinh" title=" Nam Dinh"> Nam Dinh</a> </p> <a href="https://publications.waset.org/abstracts/145972/sustainable-use-of-fresh-groundwater-lens-of-pleistocene-aquifer-in-nam-dinh-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145972.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">158</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">38</span> Design, Optimize the Damping System for Optical Scanning Equipment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duy%20Nhat%20Tran">Duy Nhat Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Tien%20Pham"> Van Tien Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Quang%20Trung%20Trinh"> Quang Trung Trinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tien%20Hai%20Tran"> Tien Hai Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Cong%20Bui"> Van Cong Bui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, artificial intelligence and the Internet of Things have experienced significant advancements. Collecting image data and real-time analysis and processing of tasks have become increasingly popular in various aspects of life. Optical scanning devices are widely used to observe and analyze different environments, whether fixed outdoors, mounted on mobile devices, or used in unmanned aerial vehicles. As a result, the interaction between the physical environment and these devices has become more critical in terms of safety. Two commonly used methods for addressing these challenges are active and passive approaches. Each method has its advantages and disadvantages, but combining both methods can lead to higher efficiency. One solution is to utilize direct-drive motors for position control and real-time feedback within the operational range to determine appropriate control parameters with high precision. If the maximum motor torque is smaller than the inertial torque and the rotor reaches the operational limit, the spring system absorbs the impact force.

Currently, most of these mobile applications seem to be extensions of the existing communication media, sometimes merely replicating the information available on the classical city web sites, and therefore provide minimal additional impact on citizen behavior and engagement. In order to overcome this challenge, we propose to use a holistic behavioral model to generate dynamic and contextualized app content based on optimizing well defined city-related performance goals constrained by the proposed behavioral model. In this paper, we will show how the data collected by the CorkCitiEngage project in the Irish city of Cork can be utilized to calibrate aspects of the proposed model enabling the design of a personalized citizen engagement app aiming at positively influencing people’s behavior towards more active participation in their communities. We will focus on the important aspect of intentions to act, which is essential for understanding the reasons behind the common value-action-gap being responsible for the mismatch between good intentions and actual observable behavior, and will discuss how customized app design can be based on a rigorous model of behavior optimized towards maximizing well defined city-related performance goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=city%20apps" title="city apps">city apps</a>, <a href="https://publications.waset.org/abstracts/search?q=holistic%20behaviour%20model" title=" holistic behaviour model"> holistic behaviour model</a>, <a href="https://publications.waset.org/abstracts/search?q=intention%20to%20act" title=" intention to act"> intention to act</a>, <a href="https://publications.waset.org/abstracts/search?q=value-action-gap" title=" value-action-gap"> value-action-gap</a>, <a href="https://publications.waset.org/abstracts/search?q=citizen%20engagement" title=" citizen engagement"> citizen engagement</a> </p> <a href="https://publications.waset.org/abstracts/58585/tackling-the-value-action-gap-improving-civic-participation-using-a-holistic-behavioral-model-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58585.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">226</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">36</span> Impact of Burning Incense/Joss Paper on Outdoor Air Pollution: An Interrupted Time Series Analysis Using Hanoi Air Quality Data in 2020</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi%20T.%20L.%20Pham">Chi T.

This study aims to measure the impact of burning joss paper and incense during Vu Lai festival (full moon of July) in Vietnam. Data of Hanoi air quality in year 2020 was used. Interrupted time series analysis was employed to examine the changes in pattern of various air quality indicators before and after the festival period. The results revealed that burning joss paper and incense led to an immediate increase of 15.94 units in the air quality index on the first day, which gradually rose to 47.4 units by the end of the full moon period. Regarding NO2, PM10, and PM25, there was no significant immediate change at the start of the intervention period (August 29th, 2020). However, significant increases in levels and an upward trend were observed during the intervention time, followed by substantial decreases after the intervention period ended (September 3rd, 2020). This analysis did not find a significant impact on CO, SO2, and O3 due to burning joss paper and incense. These findings provide valuable insights for policymakers and stakeholders involved in managing and enhancing air quality in regions where such practices are prevalent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20pollution" title="air pollution">air pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=incense" title=" incense"> incense</a>, <a href="https://publications.waset.org/abstracts/search?q=ITSA" title=" ITSA"> ITSA</a>, <a href="https://publications.waset.org/abstracts/search?q=joss%20paper" title=" joss paper"> joss paper</a>, <a href="https://publications.waset.org/abstracts/search?q=religious%20activities" title=" religious activities"> religious activities</a> </p> <a href="https://publications.waset.org/abstracts/185265/impact-of-burning-incensejoss-paper-on-outdoor-air-pollution-an-interrupted-time-series-analysis-using-hanoi-air-quality-data-in-2020" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185265.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">49</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">35</span> Accessing the 'No-Harm' Principle of Protection of the Mekong River’s Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hang%20Thuy%20Tran">Hang Thuy Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanh%20Hong%20Pham"> Hanh Hong Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Ha%20Thanh%20Hoa"> Ha Thanh Hoa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From 2009 up to now, the water quantity and water quality of the Mekong River, located in the South of Vietnam, have been significantly reduced. The phenomenon happened as a result of climate change and human activities. The Mekong River is an international source of water, flowing across the borders of 6 countries, with Vietnam downstream. Activities to block the flow or build dams to construct hydroelectricity or diversion in upstream countries are either the direct cause or the risk of further deterioration of the water quality and quantity of the Mekong River, as evidenced by two phenomena which are a saline intrusion and transboundary water pollution. The protection of the crucial source of water is done through bilateral and multilateral cooperation mechanisms, notably the Mekong River Commission, established by members of the Agreement on the Cooperation for the Sustainable Development of the Mekong River Basin 1995. In this document, under Article 7, the 'no-harm' principle requires member states to take appropriate measures to prevent causing substantial damage to other member states. This principle has been practiced through the work of a number of committees established by the commission. However, the content of the rules is undetailed, lacks an implementation monitoring mechanism, and has an unreasonable dispute solution. With such difficulties, the provisions in the principle of no-harm are not adequate to protect the Mekong River's water resources in the current context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=no-harm%20principle" title="no-harm principle">no-harm principle</a>, <a href="https://publications.waset.org/abstracts/search?q=transboundary%20water%20pollution" title=" transboundary water pollution"> transboundary water pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=Mekong%20Commission" title=" Mekong Commission"> Mekong Commission</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20source%20of%20water" title=" international source of water"> international source of water</a> </p> <a href="https://publications.waset.org/abstracts/134235/accessing-the-no-harm-principle-of-protection-of-the-mekong-rivers-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134235.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">191</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">34</span> Modeling and Simulation of Pad Surface Topography by Diamond Dressing in Chemical-Mechanical Polishing Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.Chen%20Chao-Chang">A.Chen Chao-Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Phong%20Pham-Quoc"> Phong Pham-Quoc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chemical-mechanical polishing (CMP) process has been widely applied on fabricating integrated circuits (IC) with a soft polishing pad combined with slurry composed of micron or nano-scaled abrasives for generating chemical reaction to remove substrate or film materials from wafer. During CMP process, pad uniformity usually works as a datum surface of wafer planarization and pad asperities can dominate the microscopic pad-slurry-wafer interaction. However, pad topography can be changed by related mechanism factors of CMP and it needs to be re-conditioned or dressed by a diamond dresser of well-distributed diamond grits on a disc surface. It is still very complicated to analyze and understand kinematic of diamond dressing process under the effects of input variables including oscillatory of diamond dresser and rotation speed ratio between the pad and the diamond dresser. This paper has developed a generic geometric model to clarify the kinematic modeling of diamond dressing processes such as dresser/pad motion, pad cutting locus, the relative velocity of the diamond abrasive grits on pad surface, and overlap of cutting for prediction of pad surface topography. Simulation results focus on comparing and analysis kinematics of the diamond dressing on certain CMP tools. Results have shown the significant parameters for diamond dressing process and also discussed. Future study can apply on diamond dresser design and experimental verification of pad dressing process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kinematic%20modeling" title="kinematic modeling">kinematic modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=diamond%20dresser" title=" diamond dresser"> diamond dresser</a>, <a href="https://publications.waset.org/abstracts/search?q=pad%20cutting%20locus" title=" pad cutting locus"> pad cutting locus</a>, <a href="https://publications.waset.org/abstracts/search?q=CMP" title=" CMP"> CMP</a> </p> <a href="https://publications.waset.org/abstracts/50957/modeling-and-simulation-of-pad-surface-topography-by-diamond-dressing-in-chemical-mechanical-polishing-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50957.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">255</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">33</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
