Effect of Bit Depth on Cloud Segmentation of Remote-Sensing Images

open access: yesRemote Sensing, 2023
Due to the cloud coverage of remote-sensing images, the ground object information will be attenuated or even lost, and the texture and spectral information of the image will be changed at the same time.

The effects of stereoscopic depth on completion [PDF]

open access: yesPerception & Psychophysics, 1999
Stereoscopic depth has a critical effect on completion of partially occluded figures. However, it has not strictly been distinguished whether the effect is direct or indirect through alteration of contour segmentation or parsing. Here, I report that stereoscopic depth does not influence completion of partially occluded figures when parsing is ...

Effect of Steel Reinforcement on the Minimum Depth-Span Ratio [PDF]

open access: yesEurasian Journal of Science and Engineering, 2018
Building codes and standards include methods and provisions for deflection control and determining minimum thickness of slabs and beams, also determine the immediate and long or timedependent deflection.

Effect of tramadol on depth of anaesthesia

open access: yesBritish Journal of Anaesthesia, 1996
We have studied 51 patients who were anaesthetized with propofol and suxamethonium followed by 0.7% isoflurane and 66% nitrous oxide in oxygen to see if tramadol caused lightening of anaesthesia. A two-channel EEG was recorded and music was played via headphones. Two groups received tramadol 200 and 100 mg i.v.

Influence of observation angle change on satellite retrieval of aerosol optical depth

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2021
Use of multi-angle sensors, which can perform ground observations in different view directions, provides an important technical means to acquire more comprehensive and detailed remote sensing information.

In-situ geological conditions and their controls on permeability of coalbed methane reservoirs in the eastern Ordos Basin

open access: yesFrontiers in Earth Science
The eastern Ordos Basin plays an important role in China’s coalbed methane (CBM) industry, boasting considerable CBM resources and pronounced reservoir heterogeneity, making it an ideal site for comparative research on deep and shallow CBM geology.

Domain Adaptation and Adaptive Information Fusion for Object Detection on Foggy Days

open access: yesSensors, 2018
Foggy days pose many difficulties for outdoor camera surveillance systems. On foggy days, the optical attenuation and scattering effects of the medium significantly distort and degenerate the scene radiation, making it noisy and indistinguishable. Aiming

Depth perception with gaze-contingent depth of field

open access: yes, 2014
Blur in images can create the sensation of depth because it emulates an optical property of the eye; namely, the limited depth of field created by the eye's lens. When the human eye looks at an object, this object appears sharp on the retina, but objects

Study on the Effect of Installation Depth of Pipe on Scour Depth Under the River Crossing Pipeline in Unsteady Flow [PDF]

open access: yesعلوم و مهندسی آبیاری, 2020
Water and other fluid pipes that are placed on the seabed and rivers bed change the flow pattern around them. These changes increase the shear stress of the bed and the severity of turbulence around the pipe and create a scouring hole under the pipe. The
