Predicting and mapping fire susceptibility is a top research priority in fire-prone forests worldwide. This study evaluates the abilities of Bayes Network (BN), Naïve (NB), Decision Tree (DT), Multivariate Logistic Regression (MLP) machine learning methods for prediction across Pu Mat National Park, Nghe An Province, Vietnam. The modeling methodology was formulated based on processing information from 57 historical fires set nine spatially explicit explanatory variables, namely elevation,...
Risk of flash floods is currently an important problem in many parts Vietnam. In this study, we used four machine-learning methods, namely Kernel Logistic Regression (KLR), Radial Basis Function Classifier (RBFC), Multinomial Naïve Bayes (NBM), and Model Tree (LMT) to generate flood susceptibility maps at the minor part Nghe An province Center region (Vietnam) where recurrent problems are being experienced. Performance these methods was evaluated select best method for mapping. model...
Improving the accuracy of flood prediction and mapping is crucial for reducing damage resulting from events. In this study, we proposed validated three ensemble models based on Best First Decision Tree (BFT) Bagging (Bagging-BFT), Decorate Random Subspace (RSS-BFT) learning techniques an improved susceptibility in a spatially-explicit manner. A total number 126 historical events Nghe An Province (Vietnam) were connected to set 10 influencing factors (slope, elevation, aspect, curvature,...
We proposed an innovative hybrid intelligent approach, namely, the multiboost based naïve bayes trees (MBNBT) method for spatial prediction of landslides in Mu Cang Chai District Yen Bai Province, Vietnam. The MBNBT, which is ensemble (MB) and (NBT) base classifier, has rarely been applied landslide susceptibility mapping around world. For modeling, we selected 248 locations hilly terrain study area. Fifteen conditioning factors were construction database on one-R attribute evaluation (ORAE)...
Virtual Tourism is Rapidly Expanding worldwide and serves as a practical support for traditional tourism by enhancing tourist experiences. In major cities, virtual widely utilized to advance smart promote night activities. Vietnam, Ho Chi Minh City has taken initial steps in this domain, incorporating applications cater both domestic international tourists. However, its development remains limited when compared other relevant urban destinations. This paper utilizes the...
Background: Consolidation coefficient (Cv) is a key parameter to forecast consolidation settlement of soft soil foundation as well in treatment design foundation, especially when drainage used soil. Objective: In this study, the main objective predict accurately using an artificial intelligence approach named Random Forest (RF) method. addition, we have analyzed sensitivity different combinations factors for prediction Cv. Method: A total 163 samples were collected from construction site...
Abstract Recently, the spread of white spot disease in shrimps has a major impact on aquaculture activity worldwide affecting economy countries, especially South-East Asian countries like Vietnam. This deadly is caused by White Spot Syndrome Virus (WSSV). Researchers are trying to understand and control this doing field laboratory studies considering effect environmental conditions affected WSSV. Generally, they have not considered spatial factors their study. Therefore, present study, we...
Coarse wood debris (CWD) plays a critical role in forest productivity, nutrient cycling, decomposition, and carbon sequestration, shapes the pool ecosystem. However, elemental composition of CWD varies among different types decay classes for same dominant tree species (Pinus koraiensis, PK). We compared across (Picea koraiensis-Abies nephrolepis-Pinus koraiensis (PAPF), Betula costata-Pinus (BPF), Tilia amurensis-Pinus (TPF)), considering four decay. Results showed that N, P, Mg, Mn, Na, Zn,...
Abstract This study applied remote sensing methods combining GIS and machine learning (ML) in landslide assessment zonation for the western mountainous area of Nghe An province, Vietnam. Factors affecting susceptibility are analyzed included model including terrain elevation, slope, aspect, flow accumulation, geomorphology, profile curvature, Topographic Position Index (TPI), fault density, road rainfall land use. A field survey was conducted on July, 2023 to collect ground truth data areas...
The topic "Teaching and learning English for tourism after the Covid-19 pandemic in universities solution proposals" to a growing need sustainable development of as well human resources training pandemic.In this topic, we use teaching methods such survey listing, analysis, description, synthesis examine effects on occupational training.Since then, author offers proposals about at order improve students' outcomes where concepts can be gradually built quality language major.In addition, also...
With the opening and integration of our country, we have attracted many investors from various fields all around world such as economy, society so on, leading to development changes in life, language culture Vietnamese communication. So "some issues research intercultural communication curriculum at Sai Gon University period” is a topic that has important value this worthy be paid attention for carrying out research. However, due limitation article, only discuss develop an training Master's...
To explore the positive changes in teaching activities for General or non-specialist English and proposals evaluation criteria at Sai Gon University, a methodological approach involving listing, describing, synthesizing was employed. This aimed to identify context of modern technology that enhance capabilities both lecturers students University.The purpose article is clarify effects changing results learning University lecturers’ capacity students’ language ability modifications tasks...
The purpose of this paper is to develop Vietnamese writing skills for first grade students. To achieve objective, the author conducted a study on their abilities using various research methods, specifically, survey research, statistical analysis, classification techniques, etc. Therefore, would like provide practical suggestions improving skills. These likely focus teaching and learning methods that are suitable students' current level ability. article's content valuable contribution...
Soil erosion is a naturally occurring process in mountainous areas that affects all landforms.Located Central of Vietnam, the tropical monsoon climate Da Nang City characterized by more than 70 percentage area with hilly and topography.This study objective apply Universal Loss Equation (ULSE) model developed Wischmeier Smith (1978) integrating remote sensing data Geographical Information System (GIS) tool to evaluate soil risk City, Vietnam.Rainfall erosivity (R), slope length-steepness...
Topic "Developing Vietnamese listening -speaking skills for first-grade Chinese pupils in District 5, Ho Chi Minh City during Covid 19 pandemic period" is a necessary topic that researched to improve competency Vietnam nowadays.In this article, we use the method of surveying, listing results listeningspeaking who are living City.We enumerate, describe, analyze and synthesize results, cultural conditions characteristics expressed these pupils' ability -speaking.Since then, have given some...
