Critical-depth Raman spectroscopy enables home-use non-invasive glucose monitoring. [PDF]

open access: yesPLoS ONE, 2018
One of the most ambitious endeavors in the field of diabetes technology is non-invasive glucose sensing. In the past decades, a number of different technologies have been assessed, but none of these have found its entry into general clinical use.

Critical Water Depth and Installation Curves for Submarine Cable Deployment Process

open access: yesJournal of Marine Science and Engineering, 2020
The purpose of the present paper is to propose installation curves for submarine cable deployment process for different water depths and tension deployment, emphasizing on the importance of modelling the “out of water” cable segment and the friction ...

An experimental demonstration of the critical depth principle [PDF]

open access: yesICES Journal of Marine Science, 2015
AbstractSverdrup's critical depth hypothesis, which has had an almost canonical status in biological oceanography, has recently been challenged as a universal explanation for the formation of oceanic spring blooms, and several alternative hypotheses have been proposed.

Estimating critical depth and discharge over sloping rough end depth using machine learning

open access: yesJournal of Hydroinformatics
This study uses machine learning (ML) to predict the end-depth structure's discharge and critical depth (yc). Linear regression, M5P, random forest, random tree, reduced error pruning tree, and Gaussian process (GP) are the ML methods used in this ...

Application correlation algorithm to create a new critical depth equation for gradually varied flow in trapezoidal channel using teaching–learning and studying [PDF]

open access: yesJournal of Hydraulic Structures, 2020
The critical depth is a hydraulic factor of the flow, it plays a particularly important role in studying and designing for open channels, especially during identification of water surfaces and analyzing to determine the phenomenon of a hydraulic jump in ...

Ground Vibration Response to Vibratory Sheet Pile Driving and Extraction

open access: yesBuildings, 2023
Sheet piles are extensively used as foundation structures in urban environments. However, the vibrations associated with sheet pile construction can potentially adversely affect existing buildings, as well as cause discomfort to nearby residents.

Critical depth and critical turbulence: Two different mechanisms for the development of phytoplankton blooms [PDF]

open access: yesLimnology and Oceanography, 1999
A turbulent diffusion model shows that there are two different mechanisms for the development of phytoplankton blooms. One of these mechanisms works in well‐mixed environments and corresponds to the classical critical depth theory. The other mechanism is based on the rate of turbulent mixing.

Critical Optical Depth Hypothesis for Phytoplankton Growth and Bloom. A New Graphical Approach to the Classic Sverdrup Critical Depth Model

open access: yesStudia Ecologiae et Bioethicae, 2023
A modification to the classic Sverdrup Critical Depth Model relating phytoplankton light-limited net growth in a mixed water column to its depth is presented by introducing optical depth in place of the physical depth of the column, as well as by the ...
