Constructing US - China tension index from Vietnamese media

Hoang Anh Le — 2025-05-22

This study develops the UCTV (U.S.-China Tension Index from Vietnamese
Media) to quantify the level of U.S.-China tension from the perspective of Vietnamese
media. The dataset comprises over 700,000 economic news articles collected from five
major Vietnamese economic news sources during the period of 2014–2023, utilizing
automated data collection techniques (web scraping) combined with the Python
newspaper3k library, followed by filtering through a keyword catalog and manual
validation. Analytical results demonstrate that the data from the five sources underpinning
UCTV exhibit high reliability, with internal consistency confirmed by a Cronbach’s Alpha
coefficient. The index shows significant alignment with the UCT (U.S.-China Tension
Index) of the United States and the GEPU (Global Economic Policy Uncertainty Index),
while no clear correlation is observed with the GPR (Geopolitical Risk Index). UCTV
captures substantial fluctuations associated with key geopolitical events impacting
Vietnam, such as the HD-981 oil rig incident (May 2014) and the U.S.-China Trade War
(2018–2019). This research not only provides an effective quantitative tool to assist
Vietnamese businesses and government in assessing geopolitical risks and formulating
long-term strategies amid global instability, but also offers a clearer perspective on the
dynamics of U.S.-China tension through the lens of domestic media. Furthermore, UCTV
holds the potential to serve as a foundation for advancing similar studies in other domains,

E-contracting has revolutionized modern business by streamlining and speeding up the
contracting process, turning what traditionally took months into a matter of days or hours. Advances
in artificial intelligence (AI) and widespread use of the Internet have greatly facilitated this
transformation. E-contracts comply with all required legal requirements and transform traditional
paperwork into a digital format, enabling seamless transactions in global markets. The advent of econtracts has simplified purchasing processes, allowing consumers to order, cancel, return products
and make warranty claims online with unprecedented ease. This flexibility transcends geographical
boundaries, making both national and international transactions more simple and efficient. AI plays
a key role in this new paradigm by providing tools that can review and manage large volumes of
contracts faster and more accurately than human capabilities.
The integration of AI into e-contracts has introduced new dimensions to contract management,
including the ability for AI systems to enter into contracts autonomously, a previously unimaginable
concept. This development has sparked discussion over the future legal status of AI in contract law.
Despite ongoing debates, the role of AI in contracting is increasingly being recognized, with new
standards emerging to address the unique challenges and benefits it brings. Major online
marketplaces such as Amazon, Flipkart and Alibaba exemplify the practical application of econtracts, providing users with a straightforward and efficient means to purchase goods and services.
Ease of use, instant confirmation, and comprehensive post-purchase support, including cancellations
and returns, highlight the significant improvements that AI and the Internet have brought to the
contracting process.
The integration of AI and e-contracts has fundamentally changed the way contracts are formed,
executed and managed. This technological advancement delivers increased efficiency, accessibility,
and reliability in modern business transactions, underscoring the profound impact AI will have on
the future of contract law and commerce.

Analysis of the vibrational dynamics of a two-axle vehicle with real road surface roughness amplitude

Cao Hieu Le — 2024-07-01

The calculation of automobile oscillations is crucial for evaluating stability and
vertical dynamic safety during vehicle operation. In this study, a two-axle vehicle dynamics
model is developed using differential equations to compute the vehicle's dynamic
oscillations. The Matlab-Simulink tool is utilized to solve these differential equations and
determine the dynamic response of the two-axle vehicle system subjected to external
excitations. These excitations are measured and simulated based on real road surface
irregularities recorded by a Walking Profiler device. The research results have successfully
developed a vehicle dynamics model that considers the random roughness of the road
surface during vehicle operation. The random roughness factor of the road surface is
incorporated into the simulation model as a primary excitation factor affecting the
characteristic outcomes of vehicle oscillations.
