X-ray transmittance and backscatter imaging are important methods for detecting drugs plastic explosives in the security-inspection field. In this study, we developed an analytical model based on Geant4 toolkit verified it by measuring energy spectrum images. According to model, analyzed contrasts detect concealed contrabands. The results show that significantly better than those of transmission, especially thinner organic materials. However, shelters with strong absorption scattering, gaps...
The rotational state of the downhole motor is critical for monitoring its operational condition. In this work, a self-powered multifunctional sensor (hereafter referred to as SPMS) proposed monitor speed, angle, and direction rotation without external power supply. experimental results show that SPMS can measure speed in range 0–750 r/min with an error rate less than 2% excellent linearity. addition measurement function, it also angle resolution 22.5°. Furthermore, possibility converting...
Based on the drilling results of Taishen-1 well in Sanhu area Qaidam Basin, study proposed new findings conditions source rock, reservoir, and overlaying strata, as accumulation characteristics for biogenic gas. Further, controlling factors gas two favorable zones exploration were identified based comparison geological adjacent areas. The result showed that: (1) rock is lacustrine dark mudstone, LLTOC (lower limit total organic carbon) Q1+2 (the Qigequan Formation) N Neogene) 0.25% 0.40%;...
In order to counter drug-related crimes effectively, and safeguard homeland security as well public safety, it is important inspect drugs, explosives other contraband quickly accurately from the express mail system, luggage, vehicles objects. this paper, we discuss X-ray backscatter inspection system based on a novel lobster-eye objective, which an effective technology for inspection. Low atomic number materials, such drugs explosives, leads strong Compton scattering after irradiated by...
In this Letter, we utilize the speckle model to measure average random scattering rate of fiber backscatter and analyze its dependence on length, yielding a linear fitting coefficient 0.23 ppm/m for PM980-XP fiber. We incorporate temperature coupling effect into validate model’s accuracy by examining distribution change backscattering relative amplitude spectral density backscattered power. Our findings demonstrate that typical shoulder-shaped noise in interferometer experiments is limited...
Based on the latest interpretation results of 2D seismic data, combined with drilling, logging, and geochemical reservoir‐forming conditions exclusive economic zone in Cuba's sector Gulf Mexico (Hereinafter refer to GOM) are studied systematically, oil gas accumulation model study area is predicted. The favourable exploration zones evaluated optimized. show that: ① High quality Upper Jurassic‐Lower Cretaceous potential Middle‐Lower Jurassic source rocks developed area. ② A set petroleum...
Mobile applications have gained rising popularity due to the advantages in mobile technologies. Furthermore, appearance of tablets and devices with other forms has increased diversity apps. These phenomena resulted a growing need app developers understand usage behaviors Previous studies this area mostly rely on instrumented so that scope is limited. To better at larger scale, we present an approach without assistance any device which designed identify installation packages instead traffic...
A towing PIV system in large tank at China Ship Scientific Research Center is presented, also its application the investigation on effect flow structure of juncture forms stern appendage with submarine-like main-body. The coefficients non-uniformity nominal wake for five are assessed and compared.
We present a set of graphical and combinatorial algorithms for designing mazes based on images. The designer traces regions interest in an image annotates the with style parameters. They can optionally specify solution path, which provides rough guide laying out maze's actual solution. system uses novel extensions to well-known maze construction build that approximate tone source image, express desired each region, conform user's path.
<p><strong>Introduction: </strong>Organic acids which are commonly detected in oilfield waters, can partially enhance reservoir properties. Previous studies have suggested that cleavage of the oxygen-containing functional group kerogen is a major source organic acids. However, this assumed to occur before rock enters oil window. If correct, then these dissolve only minerals rocks. Presently, no detailed study generation during whole thermal...
