Fiber Optic Sensors (FOS) offer numerous advantages for structural health monitoring. In addition to being durable, lightweight, and capable of multiplexing, they offer the ability to monitor strain in both static and dynamic mode. FOS also allow for instrumentation of large areas of a structure with long-gage sensors which helps enable global monitoring of the structure. Drawing upon these ben...

STUDY DESIGN Biomechanical testing of partially nucleotomized ovine cadaveric spines. OBJECTIVE To explore how the nucleus pulposus (NP) affects the biomechanical behavior of the intervertebral disc (IVD) by performing a partial nucleotomy via the transpedicular approach. SUMMARY OF BACKGROUND DATA Mechanical loading represents a crucial part of IVD homeostasis. However, traditional regener...

Machine tool calibration can be employed to optimise path trajectories through on- and off-line compensation of anticipated deflections, which result from a process plan, assess the machine tools capability comply with geometric dimensions tolerances plan. This work presents measurement for identification static quasi-static rotational stiffness joint 5-axis machining centres. shall serve as ba...

The research subject is the rotational stiffness of modular building metal frame nodal connection. connections has a significant impact on results calculating load-bearing building. It known that absolutely rigid exist only in theory. In practice, each connection finite stiffness, as evidenced by numerous studies researchers. When designing real objects, certain design should be carried out. As...

The double-stranded nature of DNA links its replication, transcription and repair to rotational motion and torsional strain. Magnetic tweezers (MT) are a powerful single-molecule technique to apply both forces and torques to individual DNA or RNA molecules. However, conventional MT do not track rotational motion directly and constrain the free rotation of the nucleic acid tether. Here we presen...
