Advances in highly multi-parametric measurements by mass cytometry have made possible the accurate detection of acute myeloid leukemia (AML) cells in complex cell populations. However, current informatics methods bottlenecks data processing by being labor-intensive, time-consuming, and prone to user bias. To address these problems, major efforts have been made to automate the detection of AML cells...
Rain streaks removal is an important issue of the outdoor vision system and has been recently investigated extensively. In this paper, we propose a novel tensor based video rain streaks removal approach by fully considering the discriminatively intrinsic characteristics of rain streaks and clean videos, which needs neither rain detection nor time-consuming dictionary learning stage. In specific, on...
Gas insulation equipment are widely used in high voltage electrical field, which use SF6 gas as insulation medium and have many advantages such as low maintenance and high reliability. But SF6 leakage caused by factors such as manufacturing, installation and material aging will severely reduce the insulation performance of equipment and eventually lead to the occurrence of insulation fault. Therefore,...
An electrical tuning method for terahertz quantum-cascade lasers (QCLs) is developed based on detuned intersubband absorption in coupled metallic microcavities, which works even at high operating temperatures. Continuous 4 GHz tuning for a single-mode narrow-beam 3.57 THz QCL operating at ∼ 50 K in a Stirling cryocooler is demonstrated.
Novelty detection systems aim at reducing redundant documents or sentences from a list of documents chronologically ordered. In the task, sentences appearing later in the list with no new meanings are eliminated. In an accompanying paper, the nature of novelty detection was revealed – Novelty as a combination of the PO (partial overlap) and CO (complete overlap) relations, which can be treated as...
A broadband bidirectional terahertz quantum-cascade laser operating up to 147K and emitting in the frequency range of 3.1–3.7THz is demonstrated. A three-well GaAs/AlGaAs design with 10%Al barriers is shown to be optimum for bidirectional lasing.
In this paper, we propose an automatic and efficient method to enhance edge sharpness of images. Starting from an image with blur edges, we improve the edges using transformed Heaviside functions for better visualization. In addition, we provide an efficient method to directly compute the scaling and shifting factors of the transformed Heaviside functions, so that blur edges can be improved accurately...
This paper presents a solution for the license plate recognition problem under low illumination on the basis of in-depth analysis of the characteristic of license plate images. In recent years, with the development of technologies such as optics, computers and pattern recognition, license plate recognition technology is improved constantly, but the accuracy of license plate recognition under low illumination...
In this paper, a competitive three-phase buck-type PFC converter named SWISS Rectifier is comprehensively researched to inhibit mains current distortion. The control structure which would realize PFC function but also introduce harmonic components to mains current is illustrated and improved to achieve better performance. The origin of the mains current distortion occurred at the sector boundaries...
Three-beam laser interference is used to create spot or grating patterns by three laser beams. In this paper, effect of parameters on three-beam laser interference is discussed. Computer simulation results have shown that the parameters and their deviations of incident angles, azimuthal angles and polarization states will affect the period, contrast, shape and direction of the spots of three-beam...
Tacit knowledge, specificity and complexity play adjustment role in the influence of knowledge transfer, the user can make human-machine interaction through the machine language, making deep mining and analysis to the data, so as to help the enterprise management personnel have an experiential learning from the elderly technological talents. Thus they can explore Application of Machine language during...
This article expounds the definition of information technology barriers, it explains the effects of the information technology barriers to the technological innovation of small and medium-sized enterprises, and finally puts forward the measures of a crossing the information technology barriers from the government and enterprises' point of view.
Forming a low energy consumption and environment-friendly railways industry has become an imperative work, therefore, the energy saving and emission reduction performance of railways should be paid more attention to. This paper firstly presents the current energy consumption and energy saving status quo of China's railways, and then introduces some relevant energy saving researches with respect to...
Cognitive radio (CR) and Femto-cell (FC) are both attractive technologies due to their marvelous potential to solve problems in current wireless communication systems. The creative combination of CR and FC, resulting in cognitive femto-cell (CFC), will be an essential part of the future wireless communication systems. In this paper, we develop a reconfig-urable SDR platform for implementation of cognitive...
