Modern automotive vehicles are often equipped with a budget commercial rolling shutter camera. These devices often produce distorted images due to the inter-row delay of the camera while capturing the image. Recent methods for monocular rolling shutter motion compensation utilize blur kernel and the straightness property of line segments. However, these methods are limited to handling rotationa...

CONTEXT In the South African mining sector, cardiorespiratory-specific autopsies are conducted under the Occupational Diseases in Mines and Works Act (ODMWA) on deceased mineworkers to determine eligibility for compensation. However, low levels of autopsy utilisation undermine the value of the service. OBJECTIVE To explore enablers and barriers to consent that impact on ODMWA autopsy utilisat...

Carbonate compensation depth (CCD) is an important factor in the global deep ocean and carbon cycling; however, its variabilities have not been well documented previous studies. In this study, we investigate two deep-sea cores collected from Philippine Sea terms of geochronology geochemical properties over past ~900 kyr. The principle results are as follows: (1) Two magnetozones determined sedi...

Abstract Aiming at the requirement of full-ocean-depth (operating water depth 11000 m) manned submersible to carry out gas-tight sampling operation abyss seabed sediment, a kind carrier mechanical hand-held, sediment sampler (GTSS) with function pressure-retaining and coring is designed. Firstly, volume change model pressure compensator established, it pointed that about 16.14% equal (GTSS). Se...

OBJECTIVES We analyze a reflection-mode multiple-illumination photoacoustic method which allows us to estimate optical scattering properties of turbid media based on fitting light-transport models and explore its limits in optical property estimation and depth-dependent fluence compensation. BACKGROUND Recent simulation results show significant promise for a technique called multiple-illumina...

For efficient and accurate diagnosis of ultrasound images, the appropriate time gain compensation (TGC) and dynamic range (DR) control of ultrasound echo signals are important. TGC is used for compensating the attenuation of ultrasound echo signals along the depth, and DR is for controlling the image contrast. In recent ultrasound systems, those two factors are automatically set by a system and...

This study examined the ocular compensation to lens-induced defocus in chick and the effect of interrupting lens wear on a daily basis. Eyes fitted with +10 D lenses at hatching compensated rapidly, with almost complete compensation after 4 days of lens wear; they had decreased vitreous chamber depth compared to normal eyes and were thus hyperopic when the lenses were removed. In contrast, adap...
