Summary: This study proposes a nonlinear two-dimensional multi-body human/seat model to predict the responses and body injuries of seated pilots exposed to vertical impact. A new force identification method is applied to obtain the external excitation of the system. The influence of input parameters on body injuries is assessed through global sensitivity analysis methods, showing that the backrest angle plays a crucial role.

Summary: This study investigated the seat-to-head vibration transmissibility responses under different seat materials and excitation conditions. The findings showed that the transmission effect of elastic seats was different from rigid seats and was primarily influenced by the elastic properties of the body-seat coupling.

Summary: This study demonstrates the emergence of highly ordered nanopatterns on the alloy surfaces during solidification in the Bi-Ga alloy system. The pattern-formation mechanisms involving surface-catalyzed heterogeneous nucleation were elucidated through a combination of experiments and molecular dynamics simulations. The dynamic nature and robustness of the phenomenon under different solidification conditions and for various alloy systems were further demonstrated, showing promising potential for surface- and nanoscale-based applications.

Summary: This study developed a 7-DOF seated human model and utilized a hybrid optimization method to accurately predict the response of different body segments to vertical vibrations. The experimental results revealed that the upper trunk and head were most susceptible to transmitted vibrations. The model captured the non-linearity in human biodynamics through stiffness softening.

Summary: The interaction between a rigid-flexible system and ambient fluid was numerically simulated using the immersed boundary method. It was found that as the length of the flexible filament increases, the filament experiences different modes including plate-like (P), cylinder-like (C), slender-shape (S), and wriggling (W) modes. When the filament length reaches a critical value, the second harmonic becomes dominant, indicating a transition from the S mode to the W mode, and at this transition point, the drag on the system becomes minimum. The occurrence of the S-W mode transition is caused by the increased inertia of the filament.

Summary: This article introduces a new method of digital-impulse galvanic coupling for high-speed trans-dural data transmission, which replaces tethered wires with wireless telemetry for fast data transfer and compact design. The study demonstrates that the trans-dural channel has a wide frequency response and is relatively insensitive to misalignment.

Summary: This paper introduces a novel non-iterative reconstruction scheme for the inverse source problem of time-harmonic elastic waves, utilizing a multi-frequency Fourier expansion to determine the elastic body force. The method involves selecting appropriate admissible frequencies and establishing a relationship between Fourier coefficients and the coupled-wave field of compressional and shear waves. The validity and robustness of the proposed method are verified through theoretical justifications and numerical examples.

Summary: A train seat-human body coupled dynamics model was established to predict the ride comfort of high-speed trains, and was calibrated through on-site vibration experiments. The study found that seats in the middle of the carriage had the best comfort performance, and that seat cushion stiffness and damping had a significant effect on ride comfort.

Summary: This study aimed to test the validity of an electromyography (EMG) measurement protocol for assessing the effects of anti-vibration (AV) gloves on forearm muscle activities. The results showed that wearing AV gloves increased the activities of specific forearm muscles, and these activities were correlated with glove thickness and manual dexterity scores. This refined EMG methodology can provide guidance for designing AV gloves that reduce grip exertion.

Summary: This study proposes a methodology for evaluating the integrated performance of vibration reducing gloves, taking into account manual dexterity, vibration transmission, and grip strength preservation. The results showed higher weightings for fingers vibration response in high-frequency spectra, while palm vibration and muscles' activity had higher weightings in low-frequency spectra. Gel2, air2, and hybrid gloves made of air bladder or viscoelastic gels demonstrated superior integrated performance across high- and low-frequency vibration spectra. Fabric and rubber gloves showed the best integrated performance for multiple tasks with low-frequency vibration spectrum.
