A New Predictive Hypothesis for Phase Difference Reflection in GHz

open access: yesEnvironmental Sciences Proceedings, 2023
Wave phase difference is a fundamental property that characterises the relative behaviour of transmitted signals. It has significant roles in signal wave analysis and in interpreting various propagation phenomena, which are crucial when designing ...

Effect of wavelength of sinusoidal wavy wall surface on drag and heat transfer at turbulent thermal boundary layer flow

open access: yesJournal of Thermal Science and Technology, 2018
Direct numerical simulations of thermal turbulent boundary layer flows over a wavy wall surface are performed to investigate the effect of a wavelength on drag coefficients and heat transfer performance.

Effect of wavelength and beam width on penetration in light-tissue interaction using computational methods

open access: yesLasers in Medical Science, 2017
Penetration depth of ultraviolet, visible light and infrared radiation in biological tissue has not previously been adequately measured. Risk assessment of typical intense pulsed light and laser intensities, spectral characteristics and the subsequent ...

Wavelength sensitivity in blindsight [PDF]

open access: yesNature, 1989
Blindsight--the residual visual functions observed in visualfield defects resulting from destruction of part of the primary visual cortex (striate cortex) even though visual stimuli presented in the field defect are not consciously perceived--has generated new insights into the nature of consciousness and the role of the extrastriate pathways in visual

Wavelength-Resolved PhotoATRP

open access: yesJournal of the American Chemical Society, 2022
The careful mapping of photoinduced reversible-deactivation radical polymerizations (RDRP) is a prerequisite for their applications in soft matter materials design. Here, we probe the wavelength-dependent behavior of photochemically induced atom transfer radical polymerization (ATRP) using nanosecond pulsed-laser polymerization (PLP). The photochemical

Optical Thickness of Dielectric Layer in Solar Cell Design for Improved Efficiency: A Theoretical Insight [PDF]

open access: yesPhysics Access
This study investigates the effect of varying dielectric layer thickness on the optical properties of solar cells using MATLAB. Dielectric layers with thickness ranging from 10 to 100 nm were analyzed across 200 to 1200 nm wavelengths.

Research on infrared emission spectra of pulverized coal ash deposits [PDF]

open access: yesFME Transactions, 2013
This paper deals with thermal radiation properties of ash deposits on a pulverized coal boiler of an electric power plant. Normal emittance spectra in the 2.5-25 μm interval, and total normal emittance, were measured on 2 kinds of ash layers of a mm ...

Backscatter Distributions of Persistent and Distributed Scatterers Over Wavelength: Results From X-, C-, and L-Band

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Persistent scatterer (PS) techniques are a set of important time-series tools for interferometric synthetic aperture radar (InSAR) that enable deformation analysis in highly decorrelated terrain.

Preferences of Dairy Cattle for Supplemental Light-Emitting Diode Lighting in the Resting Area

open access: yesAnimals, 2022
Light from the environment is important for vision and regulating various biological processes. Providing supplemental lighting in the stall area could allow for individually targeted or group-level control of light. This study aimed to determine whether
