In this study, the seismic response of a container crane under a ground motion was investigated by using shake table testing on a 1/20 scale container crane. The 1/20 scale container crane was designed and fabricated according to the similitude laws, utilizing three independent quantities such as geometric length, acceleration, and elastic modulus were used to design the 1/20 scale container crane.

In recent years, landslides are taking place very seriously, and tend to increase in both scope and scale, threatening people's lives and properties. Therefore, timely detection of landslide areas is extremely important to minimize damage. In this paper, an improved algorithm for partitioning data with reliability problems using multiple fuzzifiers named as TSSFC is introduced.

In this work we studied the robust stability for implicit integro-dynamic equations on time scales with nabla derivative, which is considered as a generation of differential algebraic equations and implicit difference equations. We showed the reservation of exponential stability of these equations under small Lipschitz perturbations.

Social media is integral to modern life, particularly for adolescents who spend considerable time online. However, excessive use poses significant risks to well-being, especially among adolescents who are vulnerable to compulsive social media usage. This study examines factors contributing to social media addiction among Vietnamese adolescents using the Bergen Social Media Addiction Scale (BSMAS) and the Online Fear of Missing Out Inventory (On-FoMO).

This paper aims to develop an effective method for reduction and decomposition on large matrices with low required computational resources and fast processing times. Our contribution is to design a PCA-SVD hybrid method that dividesthe feature extraction into two phases: PCA-based size reduction and SVD-based decomposition. In our method, PCA is first applied to a large matrix to extract its important components

The modelling of traffic flow using methods and models from physics has a long history. In recent years especially cellular automata models have allowed for large-scale simulations of large traffic networks faster than real time. On the other hand, these systems are interesting for physicists since they allow to observe genuine nonequilibrium effects. Here the current status of cellular automata models for traffic flow is reviewed with special emphasis on nonequilibrium effects (e.g. phase transitions) induced by on- and off-ramps.

This paper concerns a problem of finite-time stability for a class of linear singular large-scale systems with delays. Based on matrix transformations, Lyapunov function method combined with new estimation techniques, we derive sufficient conditions for solving the finite-time stability of the system.

In this paper a molecular dynamics simulation of nano-metric cutting of copper with a diamond tool is presented. MD simulations require the determination of the interaction of the involved atoms through a function of potential for the materials involved in the analysis and the accurate topography of the studied area, leading to high demand of computational time.

In 2005 it was suggested within a New York Times article that perhaps a university level qualification in film studies could be considered “the new MBA” given the moving image’s extraordinary capacity for communicating messages on a global scale (Van Ness, 2005). The increasingly prominent position of films in the academic library from the early ‘90s onwards has popularly been attributed to the rise of film studies in universities along with advances in home video technology.
