Effects of Floor System on Progressive Collapse Behavior of RC Frame Sub-Assemblages

open access: yesBuildings, 2022
The ability to predict the resistance of reinforced concrete (RC) structures to progressive collapse as a result of an interior column removal has become a need in structural design.

Analytical Simplify Models Of The Key Elements In The Alternative Load Path Within The Frame In Accidental Situation

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2015
The present document is dedicated to global behavior of a frame further to the loss of a column, taking into account the redistribution of the internal forces. Structural elements, transfer the load to the foundation, are isolated as key elements.

Multirobot Aerial Soft Manipulator for Floating Litter Collection

open access: yesAdvanced Intelligent Systems, EarlyView.
A multirobot aerial manipulator enables autonomous floating litter collection by controlling the shape of a flexible rope equipped with a hook‐based tool. Adaptive rope‐shape planning enhances grasping performance while reducing tension, demonstrating the potential of aerial robots for floating litter removal. Removing floating litter from water bodies

Statistical identification of geometric parameters for high speed train catenary [PDF]

open access: yes, 2014
Pantograph/catenary interaction is known to be strongly dependent on the static geometry of the catenary, this research thus seeks to build a statistical model of this geometry.

Occurrence of severe slugging in oil production lines and mitigation methods: A numerical simulation approach using ALFAsim®

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

A Case Study to Monitor Parallel‐Connected Ni–Cd Batteries on EMU Trains Through Compositional Data Control Charts

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Electric multiple unit (EMU) trains, widely used in modern railway transportation, use Nickel–Cadmium (Ni–Cd) batteries to power auxiliary systems on board, including lighting, ventilation, control electronics, and emergency systems. These batteries are often connected in parallel to ensure a wider power supply range for electrical loads that ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...
