With the development of social network based applications, different service approaches to achieve these applications have emerged. Users' reporting and sharing of their consumption experience can be utilized to rate the quality of different approaches of online services. How to ensure the authenticity of users' reports and identify malicious ones with cheating reports become important issues to achieve...
We propose a novel speaker-dependent (SD) approach to joint training of deep neural networks (DNNs) with an explicit speech separation structure for multi-talker speech recognition in a single-channel setting. First, a multi-condition training strategy is designed for a SD-DNN recognizer in multi-talker scenarios, which can significantly reduce the decoding runtime and improve the recognition accuracy...
In this paper, we considers the resource allocation problems for video transmission in space based information networks. The queueing system analyzed in this work is composed of multiple users and a single server. To minimize both of the time average cost and delay of the system, and subject to the constraint that the queues in the system must be stable, we introduce a predictive backpressure algorithm...
Zinc oxide (ZnO) thin film piezoelectric cantilevers were fabricated and characterized in this work The ZnO film was deposited by RF magnetron sputtering system under optimized deposition parameters at room temperature. The XRD pattern of the ZnO film showed that it has a highly preferred c-axis orientation. The cross-sectional FE-SEM picture of the ZnO film indicates that the columnar growth of ZnO...
The 5-nm-thick HfO2 film doped with 35 mol% Gd2O3 (GDH) as a high k dielectric has been epitaxially grown on Si (100) substrate by pulsed laser deposition (PLD). In situ reflection high-energy electron diffraction (RHEED) evolution of the (100)-oriented GDH during the deposition has been investigated and shows that a two-dimensional (2D) single crystalline GDH grows with a smooth surface. The in-plane...
Gold silicide nanoparticles were prepared using RF magnetron sputtering method at room temperature (RT) and subsequent annealing treatment at 300°C for 30 min in-situ in the UHV chamber. Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) were used to analyze the surface morphology and microcosmic structures of samples. SEM images revealed that nanoparticles with sizes of...
Si nanoparticles and nanowires have been synthesized on Si substrates by pulsed laser ablation (PLA). The Si nanowires which have a crystalline core with an amorphous shell have been grown on the Si nanoparticles with increase of the ablation time. The obvious blue shift has been observed from the photoluminescence (PL) spectrum.
