Evolutionary Computation-Based Active Mass Damper Implementation for Vibration Mitigation in Slender Structures Using a Low-Cost Processor

Actuators, 2023
This work is devoted to design, implement and validate an active mass damper (AMD) for vibration mitigation in slender structures. The control law, defined by means of genetic algorithm optimization, is deployed on a low-cost processor (NI myRIO-1900 ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Software for calculation of pedestrian-induced vibration of floors

, 2022
Trendovi u savremenoj arhitekturi, koji diktiraju projektovanje komercijalnih i stambenih zgrada sa otvorenim prostorom, prouzrokovali su problem prekomernih vibracija međuspratnih konstrukcija velikih raspona usled aktivnosti ljudi koji se po njima kreću. Saniranje prekomernih vibracija već izgrađenih konstrukcija je skupo i vremenski zahtevno.

Bamboo Medical Application: A State‐of‐the‐Art Review

Advanced Materials Technologies, EarlyView.
This review presents a structured classification of bamboo's current use in healthcare. It organizes applications into medical textiles and medical devices, with further divisions based on function and level of invasiveness. It also examines material utilization based on bamboo's structural role, highlighting how it supports both protective and ...

Experimental Study of Bending and Torsional Effects in Walking-Induced Infrastructure Vibrations: The Pasternak Footbridge

Infrastructures
Slender, lightweight and modern footbridges are particularly susceptible to vibrations induced by pedestrian activity. While extensive research has focused on vertical and lateral forces produced by walking, torsional moments generated by eccentrically ...

Role of In-Field Experimental Diagnostic Analysis for the Derivation of Residual Capacity Indexes in Existing Pedestrian Glass Systems

Buildings, 2023
The use of simplified tools in support of the mechanical performance assessment of pedestrian structures is strongly attractive for designers due to practical efficiency, as well as for researchers in terms of innovation and the assessment of new ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Control of pedestrian-induced vibrations of long-span bridges

Structural Control and Health Monitoring, 2006
Sealed tuned liquid column dampers, with a gas-spring effect taken into account are ideally suited to increase the effective structural damping of bridges vibrating in the low-frequency band, up to about 5 Hz. Modal tuning in analogy to the classical mechanical damper followed by fine-tuning in state space, render the parameter optimal and the control ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
