Expanding the "Active Layer"

Ashmore, Peter, Peirce, Sarah, Leduc, Pauline · Scholarship@Western (Western University) · 2018

Church and Haschenburger (2017) make helpful distinctions around the issue of defining the active layer, with which we agree. We propose expanding discussion and definition of the ”active layer” in fluvial bedload transport to include the concept of the “morphological active layer”. This is particularly applicable to laterally unstable rivers (such as braided rivers) in which progressive morphological change over short time periods is the process by which much of the bedload transport occurs. The morphological active layer is also distinguished by variable lateral and longitudinal extent continuity over a range of flows and transport intensity. We suggest that the issue of forms of active layer raised by Church and Haschenburger opens up an important discussion on the nature of bedload transport in relation to river morpho-dynamics over the range of river types.

What is the “active layer”?

Michael Church, J.K. Haschenburger · Water Resources Research · 2016

Abstract We note the presence in the literature of two different concepts of the term “active layer” in relation to fluvial sediment transport. It has been used to represent the current dynamically active streambed surface, or to represent the depth of event‐scale scour and fill. These concepts involve distinct length and time scales. We propose that, when the distinction is important, the concepts be distinguished as either a “dynamical active layer” or an “event active layer.”

Double active layer semiconductor laser

LOGAN, RALPH A., TSANG, WON-TIEN · Institutional Repository of Xi'an Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (Xian Institute of Optics and Precision Mechanics) · 1986

A double active layer semiconductor laser having single longitudinal mode operation is described. The laser comprises first and second active layers which are separated from each other by an intermediate barrier layer but are optically coupled to each other so that, effectively, single mode operation results.

Single active layer electrochromic devices

Ram, Manoj Kumar, Stefanakos, Elias K. · Digital Commons - University of South Florida (University of South Florida) · 2023

In one embodiment, an electrochromic device includes a single active layer configured to be alternately placed in a light-transmitting state in which relatively large amounts of light can be transmitted through the active layer and a light-blocking state in which relatively small amounts of light can be transmitted through the active layer, wherein the device comprises no other layers of material that contribute to transitioning between the two states.
