This paper presents the morphological evolution characteristics of a droplet impacting V-shaped wall by using lattice Boltzmann method (LBM). Four parameters are investigated comprehensively. The vary over wide ranges: surface wettability ( $$60^\circ \le \theta ^{eq} 120^\circ $$ ), Weber number $$102.27 \text {We} 3681.82$$ bending angle (90 $$^\circ 180^\circ and eccentricity ratio (0 $$\le ...

Microcantilever platforms with integrated piezoresistors have found versatile applications in the field of clinical analysis and diagnostics. Even though treatise encompasses numerous design details of the cantilever based biochemical sensors, a majority of them focus on the generic slender rectangular cantilever platform mainly due to its evolution from the atomic force microscope (AFM). The r...

Electrostatic MEMS transducer driven by repulsive force is an attractive possibility and has advantages of avoiding the pull-in instability, tuning natural frequency, achieving high sensitivity applying enough voltages. In this work, a “T”-shaped beam, which formed attaching secondary beam perpendicular to primary cantilever at tip, introduced its nonlinear dynamics analyzed. A reduced-order mo...

a relationship based on the modified couple stress theory is developed to investigate the flexural sensitivity of an atomic force microscope (afm) with assembled cantilever probe (acp). this acp comprises a horizontal cantilever, two vertical extensions and two tips located at the free ends of the extensions which form a caliper. an approximate solution to the flexural vibration problem is obta...

We compared the results ten years after an inverted V-shaped high tibial osteotomy with those of a historical series of conventional closing-wedge osteotomies. The closing-wedge series consisted of 56 knees in 51 patients with a mean follow-up of 11 years (10 to 15). The inverted V-shaped osteotomy was evaluated in 48 knees in 43 patients at a mean follow-up of 14 years (10 to 19). All the pati...

Northern gannets (Sula bassana) are considered to obtain prey usually by rapid, vertical, shallow plunge dives. In order to test this contention and investigate underwater foraging behaviour, we attached two types of data-logging systems to 11 parental northern gannets at Funk Island in the North-Wiest Atlantic. We documented, for the first time to the authors' knowledge, gannets performing lon...
