The Effect of Structural Equation Modeling on Chatbot Usage: An Investigation of Dialogflow
Vinh T. Nguyen, Chuyen T. H. Nguyen
This study aims to understand users' perceptions of using the Dialogflow framework and verify the relationships among service awareness, task-technology fit, output quality, and TA…
A systematic review of structural equation modeling in augmented reality applications
Vinh The Nguyen, Chuyen Thi Hong Nguyen
The purpose of this study is to present a comprehensive review of the use of structural equation modeling (SEM) in augmented reality (AR) studies in the context of the COVID-19 pan…
Factors influencing to use of Bluezone
Vinh T. Nguyen, Anh T. Nguyen, Tan H. Nguyen +1
This study aims to understand the main factors and their influence on the behavioral intention of users about using Bluezone. Surveys are sent to users through the Google Form tool…
Factors Influencing Intention to use the COVID-19 Contact Tracing Application
Vinh T. Nguyen, Chuyen T. H. Nguyen
This study investigated the effects of variables influencing the intention to use the COVID-19 tracker. Experiment results from 224 individuals revealed that performance expectatio…
Revisiting Over-smoothing and Over-squashing Using Ollivier-Ricci Curvature
Khang Nguyen, Hieu Nong, Vinh Nguyen +3
Graph Neural Networks (GNNs) had been demonstrated to be inherently susceptible to the problems of over-smoothing and over-squashing. These issues prohibit the ability of GNNs to m…
UBERT: A Novel Language Model for Synonymy Prediction at Scale in the UMLS Metathesaurus
Thilini Wijesiriwardene, Vinh Nguyen, Goonmeet Bajaj +7
The UMLS Metathesaurus integrates more than 200 biomedical source vocabularies. During the Metathesaurus construction process, synonymous terms are clustered into concepts by human…
Evaluating Biomedical BERT Models for Vocabulary Alignment at Scale in the UMLS Metathesaurus
Goonmeet Bajaj, Vinh Nguyen, Thilini Wijesiriwardene +5
The current UMLS (Unified Medical Language System) Metathesaurus construction process for integrating over 200 biomedical source vocabularies is expensive and error-prone as it rel…
Lech's Inequality for the Buchsbaum-Rim Multiplicity and Mixed Multiplicity
Vinh Nguyen, Kelsey Walters
We generalize an improved Lech bound, due to Huneke, Smirnov, and Validashti, for the Buchsbaum-Rim multiplicity and mixed multiplicity. We reduce the problem to the graded case an…
Modelling Localisation and Spatial Scaling of Constitutive Behaviour: a Kinematically Enriched Continuum Approach
Giang Dinh Nguyen, Chi Thanh Nguyen, Vinh Phu Nguyen
It is well known that classical constitutive models fail to capture the post-peak material behaviour, due to localisation of deformation. In such cases the concept of Representativ…
An extended isogeometric analysis for vibration of cracked FGM plates using higher-order shear deformation theory
Loc V. Tran, Vinh Phu Nguyen, M. Abdel Wahab +1
A novel and effective formulation that combines the eXtended IsoGeometric Approach (XIGA) and Higher-order Shear Deformation Theory (HSDT) is proposed to study the free vibration o…
Nitsche's method for two and three dimensional NURBS patch coupling
Vinh Phu Nguyen, Pierre Kerfriden, Marco Brino +2
A Nitche's method is presented to couple non-conforming two and three dimensional NURBS (Non Uniform Rational B-splines) patches in the context of isogeometric analysis (IGA). We p…
Isogeometric cohesive elements for two and three dimensional composite delamination analysis
Vinh Phu Nguyen, Pierre Kerfriden, Stephane Bordas
Isogeometric cohesive elements are presented for modeling two and three dimensional delaminated composite structures. We exploit the knot insertion algorithm offered by NURBS (Non…
An isogeometric analysis for elliptic homogenization problems
H. Nguyen-Xuan, T. Hoang, V. P. Nguyen
A novel and efficient approach which is based on the framework of isogeometric analysis for elliptic homogenization problems is proposed. These problems possess highly oscillating…
Isogeometric analysis: an overview and computer implementation aspects
Vinh Phu Nguyen, Stéphane P. A. Bordas, Timon Rabczuk
Isogeometric analysis (IGA) represents a recently developed technology in computational mechanics that offers the possibility of integrating methods for analysis and Computer Aided…
