3D stability analysis method of concave slope based on the Bishop method
In order to study the stability control mechanism of a concave slope with circular landslide, and remove the influence of differences in shape on slope stability, the limit analysis method of a simplified Bishop method was employed.

Experimental and Numerical Investigation of the Heat Transfer of Honeycomb-Structured Tubes
Tube bundle recuperators are generally designed to operate with smooth tubes. Structured tubes can be used to increase the efficiency of recuperators. Compared to smooth tubes, the surface for heat transfer is increased and thus heat transfer is enhanced.

Assessment of Turbulence Models over a Curved Hill Flow with Passive Scalar Transport
An incoming canonical spatially developing turbulent boundary layer (SDTBL) over a 2-D curved hill is numerically investigated via the Reynolds-averaged Navier–Stokes (RANS) equations plus two eddy-viscosity models: the K−ω SST (henceforth SST) and the ...

Seat-to-Head Transmissibility Responses of Seated Human Body Coupled with Visco-Elastic Seats
This study investigated the seat-to-head vibration transmissibility (STHT) responses of 58 subjects (31 males and 27 females) seated on three different elastic seats with (WB) and without back support (NB) and under three levels of vertical vibration (0 ...
