Tapered transmission line technique based graded matching layers for thickness mode piezoelectric transducers [PDF]

, 2009
Conventionally, in order to acoustically match thickness mode piezoelectric transducers to a low acoustic impedance load medium, multiple quarter wavelength (QW) matching layers are employed at the front face of the device.

Layer by Layer – Combining Monads [PDF]

, 2018
We develop a method to incrementally construct programming languages. Our approach is categorical: each layer of the language is described as a monad. Our method either (i) concretely builds a distributive law between two monads, i.e. layers of the language, which then provides a monad structure to the composition of layers, or (ii) identifies ...

Burning Graphene Layer-by-Layer [PDF]

Scientific Reports, 2015
AbstractGraphene, in single layer or multi-layer forms, holds great promise for future electronics and high-temperature applications. Resistance to oxidation, an important property for high-temperature applications, has not yet been extensively investigated.

Layer by layer

TNOA Journal of Ophthalmic Science and Research
This thesis investigates the relationship between structural and functional aspects of the visual cortex by modelling parts of the outer structures of the brain. In particular, it studies the dynamics of the brain during bistable perception. This is a phenomenon in which an observer changes the interpretation of what he perceives without the visual ...

Layer-by-layer epitaxy of multi-layer MoS2 wafers

National Science Review, 2022
Abstract The 2D semiconductor of MoS2 has great potential for advanced electronics technologies beyond silicon. So far, high-quality monolayer MoS2 wafers have been available and various demonstrations from individual transistors to integrated circuits have also been shown.

Turbulent dispersion in cloud-topped boundary layers [PDF]

, 2009
Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

Characterization of nano-oxide layers fabricated by ion beam oxidation [PDF]

, 2002
In this paper, a remote O2 ion source is used for the formation of nano-oxide layers. The oxidation efficiency was measured in CoFe-oxide films, and a decrease of the oxide layer with the pan angle and the oxidation pressure is observed.

Reconstruction of the Casting Technology in the Bronze Age on the Basis of Investigations and Visualisation of Casting Moulds

Archives of Foundry Engineering, 2017
During excavation of the cremation cemetery of urnfield culture in Legnica at Spokojna Street (Lower Silesia, Poland), dated to 1100-700 BC, the largest - so far in Poland – a collection of casting moulds from the Bronze Age was discovered: three moulds ...

Flock Factors Correlated with Elevated Mortality in Non-Beak Trimmed Aviary-Housed Layers

Animals, 2022
The use of non-cage housing systems for layers is increasing in Europe and elsewhere. Knowledge of factors that may affect mortality in these systems is important to be able to improve animal welfare, reduce mortality and enhance sustainability.
