With the rapid development of modern manufacturing, more precision and higher efficiency are required for the detection technology. The vision-based detection system is playing a more important role in modern manufacturing because of its real-time and non-contact detection advantages. In this paper, we propose a vision-based online detection system for measuring diameter and thickness of the support...
The emerging Non-Volatile Memory (NVM) connected to the memory bus provides opportunities for high-performance file accesses for its near-DRAM speed and byte-addressability. In this paper, a high-performance hybrid file system, called Hybrid Memory File System (HMFS), is designed and implemented to exploit the high speed of NVM and the large capacity of block devices. A file in HMFS can be stored...
This paper puts forward a new discrete frequency control method of induction motor based on thyristor control, the hexagon flux linkage consisting of voltage space vector is triggered in multiple power cycle, and the hexagon flux linkage locus control of induction motor is realized. Through adjusting the trigger sequence of trigger angle and vector, the magnitude and direction of flux linkage are...
This paper reports on an integrative approach to a fingerprint sensor for an active matrix liquid crystal display (AMLCD). By redesigning the current driver hydrogenated amorphous silicon (a-Si:H) thin-film transistor (TFT) in the display pixel and making it a dual-gate photosensitive TFT with a -shape channel, a fingerprint-sensor-integrated display pixel can be enabled with a potentially high...
In this paper a paraxial imaging system with incoherent illumination is interpreted as a signal processing system in which a thin lens performs a forward angular transform on light rays traveling through it. Inverse angular transform exists and could be performed by another thin lens which coincides its focus plane with the first. The common focus plane acts as an angular domain, on which filtering...
The precession feature of space target provides an effective approach for target recognition. However, with the requirements that target detection and tracking to be completed successfully before the processing of precession features extraction can be implemented, the existing methods demand radar resources allocation for target detection, tracking and feature extraction, respectively, thus reducing...
Deep Web contains a vast amount of valuable information, which can be picked and exploited by data integration. A crucial step of Deep Web integration is discovering semantic correspondences over multiple Web databases, which known as schema matching. In this paper, we propose a schema matching method based on concept-word and semantic-heterogeneity for Deep Web. Firstly, the method preprocesses schema...
In this paper, we propose a novel formulation for building accurate pixel-wise alignments between remote sensing images under non-rigid distortions. Our formulation involves two variables: the first is a discrete displacement flow field similar to optical flow which controls the pixel-wise correspondence and allows piecewise smoothness, while the second is a continuous spatial transformation which...
A new entry trajectory planning approach based on quasi-three-dimensional acceleration guidance for hypersonic glide vehicles is proposed. In order to improve the maneuvering capability of entry vehicles, the planner proposed in this paper leave both angle of attack and bank be free, which means the traditional Shuttle type planner will not work. To settle the problem, the planner plans a quasi-three-dimensional...
Transparent gate-structured field emitter arrays (FEAs) using ZnO nanowire cold cathode were fabricated. By using indium tin oxide(ITO) as the materials for both the cathode and gate electrode, the ZnO nanowire FEAs shows more than 76% transmission in the visible light region. Such transparent FEAs have potential applications in double-sided field emission display.
The B/LaB6 hierarchical heterojunction nanostructures have been successfully fabricated on Si substrate by CVD technique. The branch-like morphology may be beneficial to improving their field emission (FE) properties by increasing the aspect ratio or growth density of the emitters. The results show that the threshold field of the B/LaB6 branch-like nanoheterojunctions is 21.6 V/μm (@1 mA/cm2) and...
Most existing discriminative tracking methods model a target object as a whole and train a tracker based on holistic templates, which cannot effectively deal with partial occlusions. Instead, in this paper, by treating the target as a collection of local patches, we propose a novel tracking approach based on boosted local classifiers. Initially, a set of local patches are sampled to train a set of...
Amorphous indium-gallium-zinc-oxide thin film transistor (a-IGZO TFT) with offset structure is fabricated for active-driving of ZnO nanowire field emitters. ZnO nanowire field emitters grown by thermal oxidation method is integrated with the a-IGZO TFT. The results proved that the growth process of ZnO nanowires is compatible with the a-IGZO TFT fabrication process.
For any binary-input channel with perfect state information at the decoder, if the mutual information between the noisy state observation at the encoder and the true channel state is below a positive threshold determined solely by the state distribution, then the capacity is the same as that with no encoder side information. A complementary phenomenon is revealed for a similarly defined quantity.
Land cover change detection is a comprehensive procedure involved with several interlinked steps. As a large number of change detection algorithms have been developed depending on different requirements, it becomes difficult for common end-users to select an appropriate change detection workflow. To address the challenge, this paper presents an online land cover change detection system with web service...
For application in a diode flat-panel X-ray source, large area patterned WO3 nanowires were grow on indium-tin-oxide (ITO) glass substrate by using a thermal oxidation method. It is found that the thickness of the ITO layer influences the length of the prepared WO3 nanowires. The phenomenon is attributed to the change of stress of the ITO glass substrate. The field emission properties of WO3 nanowires...
