In order to explore the optimal decolorization technology of paulownia wood suitable for middle and small Enterprises to obtain its high added values, the chemical processing method was used to solve the difficult problem of paulownia wood decolorization. The results showed that: 1) temperature, pressure, time and treatment solution concentration all had significant effects on the decolorizatio...

An empirical model is proposed to solve the problem that exists in in-orbit calibration method for TDICCD camera in this paper. The method brings in the line frequency normalization and virtual image stitching from TDICCD images to the preprocessing procedure, which makes the virtual mosaic images has the same characteristics as the regular Linear push-broom CCD images, therefore the interior a...

Non-linear camera models are playing an increasingly important role in computer graphics, especially in image based rendering and non-photorealistic rendering. We introduce ARTcams as simple non-linear cameras, which are unique in combining both geometric projection and non-geometric attributes such as colour into a single model. The geometric component of an ARTcam subsumes many contemporary n...

This paper describes a data set collected by an autonomous ground vehicle testbed, based upon a modified Ford F-250 pickup truck. The vehicle is outfitted with a professional (Applanix POS-LV) and consumer (Xsens MTi-G) inertial measurement unit (IMU), a Velodyne 3D-lidar scanner, two push-broom forward looking Riegl lidars, and a Point Grey Ladybug3 omnidirectional camera system. Here we prese...

The two video satellites of the second and third batch Zhuhai-1 microsatellites (referred to as OVS-2A/3A) are operational with their hyperspectral satellites, which improves data acquisi-tion capability remote sensing satellite constellation. Contrary linear array push-broom plane CCD OVS is equipped a planar Bayer pattern sensor, can obtain single-band grayscale images by imaging. Additionall...

BACKGROUND: We have previously shown that use of an EC brush device in combination with the Rovers Cervex-Brush (SurePath broom) offered no significant improvement in EC recovery. Here we determine if use of additional collection devices enhance the diagnostic utility of the SurePath Pap for gynecologic cytology. METHODS: After informed consent, 37 women ages 18-56 receiving their routine cervi...

This paper focuses on the design of a new optical cone and pendulum scanning imaging mode for micro-nanosatellites. kind satellite uses high-resolution camera with small plane to achieve ultra-wide coverage through three-dimensional motion camera’s wobble, spin, orbital motion. First, this designs single-camera constant speed OCPSI (optical imaging) mode. On premise ensuring coverage, parameter...

DNA was isolated from clover proliferation (CP) mycoplasmalike organism (MLO)-diseased periwinkle plants (Catharanthus roseus (L.) G. Don.) and cloned into pSP6 plasmid vectors. CP MLO-specific recombinant DNA clones were biotin labeled and used as probes in dot hybridization and restriction fragment length polymorphism analyses to study the genetic interrelatedness among CP MLO and other MLOs,...

MicroRNAs (miRNAs) play an important role in responding to biotic and abiotic stresses in plants. Jujube witches'-broom a phytoplasma disease of Ziziphus jujuba is prevalent in China and is a serious problem to the industry. However, the molecular mechanism of the disease is poorly understood. In this study, genome-wide identification and analysis of microRNAs in response to witches'-broom was ...
