With neural network theory quickly development, image intelligent processing is increasingly applied. This paper focuses on studying image information nonlinear property and eliminating noise way, combines the features of self-adaptive and nonlinearity with neural network then puts forward a new integrated method which combines neural networks with nonlinear filter. The research and experiment shows...
This paper considers the problem of identifying sparse dynamical graphical models from input/output data. Our main result shows that this problem can be recast into an expanded atomic-norm minimization framework that allows for enforcing block-sparsity. This approach leads to efficient algorithms capable of handling large data sets, unknown inputs and fragmented data records. These results are illustrated...
A trust-based mixed-initiative scheme for the bilateral teleoperation of mobile robotic systems is proposed. In a mixed-initiative control scheme, the control task is shared between human and an in-situ autonomous robot controller. In a bilateral haptic teleoperation scheme, a human operator controls a robot remotely through some control device while receiving haptic force feedback cues. The bilateral...
The paper reports the characterization of a dysprosium doped ZBLAN fiber amplifier intended to be used in mid infrared applications. Using a single-frequency 1064-nm laser pump with 1.5 W, two different fiber lengths were characterized for their losses, coupling efficiency, absorption and enhancement.
We proposed a humidity sensor based on perfect metamaterial absorber. The sensor is composed of three layers, which are metallic particle array on the top, porous silicon in the middle layer and metallic film at the bottom. It is shown that the resonant wavelength displays significant red-shift with the increasing effective permittivity of porous silicon, which is influenced by the filling fraction...
In this work, a design-technology co-optimization (DTCO) platform for 7nm node nanowire and beyond is demonstrated for the first time. The platform extends from predictive TCAD simulations through compact model extraction to circuit simulation. The impact of different cross-section geometries, design of experiment, parasitic effects, global variation and local variation are accurately and efficiently...
In view of the current problems of system evaluation and decision support, an advanced theory of evaluation based on data station was proposed. The system effectiveness from different aspects was analyzed. For massive and non-structural characteristics a model of simulation data refinement and reconstruction processing was constructed, in order to meet different demands for system analysis a data...
We have developed an all-solid-state two-step process(2SSS) for fabrication of Cu2ZnSnSe4(CZTS) devices. Raman spectra are used to determine and control secondary phases and formation of excess MoSe2 at the CZTS/Mo interface due to over selenization. While processing at temperatures above 450 C decreases ZnSe and CuSe phases, a temperature driven interface recombination mechanism reduces Jsc and FF...
The multipath estimation of global navigation satellite system (GNSS) is actually a state estimation problem. Extended Kalman Alter (EKF) is a good estimator for state estimation in linear systems. However, the estimation results of EKF fluctuate obviously around actual values. To solve the problem, a sliding average EKF is proposed. In the sliding average EKF, EKF filtering results are smoothed by...

During the smooth running of EAST (Experimental Advanced Superconducting Tokamak), a perfect network management system guaranteeing a robust network is important. In the present complex network infrastructure, it is a daunting task to manage all the devices manually in a network and make sure they are not only up and running but also performing optimally. Therefore, a web-based software system is...
The reactions have been accompanied ultraviolet (UV) radiation and electron impact with discharge plasmas in water-gas mixture, which can generate oxides such as ozone (O3), hydrogen peroxide (H2O2) and nitrogen oxides (NOx). Two plasma processing systems were established by means of a dielectric barrier discharge (DBD) arrays in water mist spray and an atmospheric pressure plasma jet (APPJ) immersed...
Due to an extensive use of spatial-temporal prediction techniques, a large amount of the spatial-temporal dependency is incurred in video coding. To optimize coding performance in the block-based hybrid coding architecture, rate-distortion optimization (RDO) techniques are widely employed based on different levels ranging from frame-level to slice-level, to coding tree unit (CTU)-level, coding unit...
This paper proposes a new hybrid method for super short-term solar power prediction. Solar output power usually has a complex, nonstationary, and nonlinear characteristic due to intermittent and time varying behavior of solar radiance. In addition, solar power dynamics is fast and is inertia less. An accurate super short-time prediction is required to compensate for the fluctuations and reduce the...
Submilisecond laser anneal has been experimentally investigated for porogen removal and its ability to improve the mechanical strength in oxycarbosilane ultra low-k films compromised due to the introduction of porosity. We report the occurrence of extensive bond rearrangements inferred from Fourier-transform infra-red (FTIR) spectroscopy, elastic recoil detection (ERD) and spectroscopic ellipsometry...
Integrated voltage regulators (IVRs) are one of the main trends in power delivery networks (PDNs) for electronic systems. A major challenge in the IVR design is to achieve sufficient integration / minimization of the required passive components of the IVR while still maintaining high power efficiency. This paper demonstrates that a buck converter type IVR designed with package embedded magnetic core...

The results showed that, regardless of the graphical...
In the study, a new design of synchronous permanent magnet bike dynamotor (SPMBD) with interdigitated magnetic resistance route (IDTMR) structure was proposed to enhance the efficiency of generator by changing the magnetic route structure.

An elementary step of trap and detrap processes of electron in the tunnel oxide during program/erase in NAND Flash memory is precisely studied. Owing to the high electric field during program and erase (P/E), the electron trapping and detrapping occur at the same time. Consequently, the detrapping process only leaves electrons in the deeper trap energy state (Etrap) than 3.5 eV. In addition, as-grown...
