This paper compares and contrasts our own technical solutions with several others in the literature. If you look at the comparison pictures and tables in this (open access) paper, you will see that our solutions are very competitive. https://lnkd.in/d7Rh6qxg

Vibration movement is necessary for a sound to occur. Vibration is the back-and-forth movement of an object. For the violin sound to occur, a vibration must occur. 👉 Subscribe to our tech newsletter, The Blueprint, which is your daily source of tech, science, and engineering innovation.

Abstract By applying a production method, she found little evidence for the hypothesis that balance is favorable for the aesthetical appreciation of pictures. Instead, she observed that other construction principles competing with balance, such as bilateral symmetry and closeness, were applied. The aim of the present study was to repeat some of Puffer’s experiments with modern methods and to examine whether her results are replicable. In two experiments, we also found little to no evidence for balance. Moreover, as in Puffer’s study, participants used closeness and bilateral symmetry as principles. However, compared to that study, the relative frequency of use of these principles was quite different.

Our new paper on the topics of "Acoustofluidic Diversity Achieved by Multiple Modes of Acoustic Waves Generated on Piezoelectric-Film-Coated Aluminum Sheets" has just been published on line in journals of "ACS Applied Materials & Interfaces" (IF=8.3). https://lnkd.in/ddS9bKMA https://lnkd.in/dgiia3we Excitation of multiple acoustic wave modes on a single chip is beneficial to implement diversified acoustofluidic functions. Conventional acoustic wave devices made of bulk LiNbO3 substrates generally generate few acoustic wave modes once the crystal-cut and electrode pattern are defined, limiting the realization of acoustofluidic diversity. In this paper, we demonstrated diversity of acoustofluidic behaviors using multiple modes of acoustic waves generated on piezoelectric-thin-film-coated aluminum sheets. Multiple acoustic wave modes were excited by varying the ratios between IDT pitch/wavelength and substrate thickness. Through systematic investigation of fluidic actuation behaviors and performances using these acoustic wave modes, we demonstrated fluidic actuation diversities using various acoustic wave modes and showed that the Rayleigh mode, pseudo-Rayleigh mode, and A0 mode of Lamb wave generally have better fluidic actuation performance than those of Sezawa mode and higher-order modes of Lamb wave, providing guidance for high-performance acoustofluidic actuation platform design. Additionally, we demonstrated diversified particle patterning functions, either on two sides of acoustic wave device or on a glass sheet by coupling acoustic waves into the glass using the gel. The pattern formation mechanisms were investigated through finite element simulations of acoustic pressure fields under different experimental configurations.

Key insights of the research: •Proposed a method that can distinguish the drowsy state from the normal state of the driver on the low-resolution images of faces and eyes observed from an oblique viewing angle. •Proposed a  Drowsiness Metric (DM), which is derived from a designed formula, it serves as a quantifiable indicator of the driver’s alertness level and takes account of various facial expressions. A critical making step follows the metric calculation. •This research exemplifies the fusion of image processing, facial analysis, and intelligent decision-making to create a responsive and reliable drowsiness monitoring system.
