An Intelligent Piezoelectric System Integrating Self‐Sensing and Autonomous Operation for Adaptive Vibration Control

Advanced Intelligent Systems, EarlyView.
An intelligent piezoelectric vibration control system integrating self‐sensing, autonomous operation, and adaptive bias‐flip synchronized switching damping (SSD) is developed. The system detects vibration extrema, executes synchronized switching control, and autonomously establishes the bias voltage without external sensing instruments, achieving ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Additional lateral meniscus centralization reduces residual anterolateral rotatory instability after anterior cruciate ligament reconstruction and lateral meniscus repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aimed to examine the effects of lateral meniscus (LM) centralization on anterolateral rotational stability in patients with anterior cruciate ligament (ACL) and LM injuries. The hypothesis was that performing LM repair and centralization on knees with LM lesions would control anterolateral rotatory instability (ALRI ...
