Audio bandwidth extension (BWE) has emerged as an important tool for the satisfactory performance of low bitrate audio and speech codecs. In the existing BWE method, the high frequency (HF) excitation signals are generated by replicating the low frequency (LF) band directly. However, the coding perception quality will degrade if the correlation between LF and HF bands becoming weak. In this paper, we proposed a new algorithm to restore the HF excitation signals using audio super-resolution. The experiments shown the new algorithm have an outstanding performance for rebuilding HF excitation signals compare with the conventional replication method. In addition, we also provided a new BWE scheme based on audio super-resolution. According to our experimental results, in compare with LPC-based BWE, the subjective listening quality increased by 13% under the same bitrates;in compare with eSBR, the bitrates drop by 63.7% and have the approximate subjective listening quality. © Springer International Publishing AG 2016.

In the process of investigating a case, face image is the most interesting clue. However, due to the limitations of the imaging conditions and the low-cost camera, the captured face images are often Low- Resolution (LR), which cannot be used for criminal investigation. Face image super-resolution is the technology of inducing a High-Resolution (HR) face image from the observed LR face image. It has been a topic of wide concern recently. In this paper, we propose a novel face image superresolution method based on Tikhonov Regularized Neighbor Representation, which is called TRNR for short. It can overcome the technological bottlenecks (e.g., instable solution) of the patch representation problem in traditional neighbor embedding based image super-resolution method. Specially, we introduce the Tikhonov regularization term to regularize the representation of the observation LR patch, which can give rise to a unique and stable solution for the least squares problem and produce detailed and discriminant HR faces. Extensive experiments on face image super-resolution are carried out to validate the generality, effectiveness, and robustness of the proposed algorithm. Experimental results on the public FEI face database show that the proposed method plays a better subjective and objective performance, which can recover more fine structures and details from an input low-resolution image, when compared to previously reported methods. © Springer International Publishing Switzerland 2016.

The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the South African Radio Astronomy Observatory (SARAO) Square Kilometer Array (SKA) site in South Africa. Each of the 6 m, f/0.23 dishes will be instrumented with dual-polarisation feeds operating over a frequency range of 400-800 MHz. Through intensity mapping of the 21 cm emission line of neutral hydrogen, HIRAX will provide a cosmological survey of the distribution of large-scale structure over the redshift range of 0.775 © 2021, CC BY.

Meta-q-plate for complex beam shaping

Scientific Reports 2016年第1期6卷 1-7页

作者： Ji, Wei Lee, Chun-Hong Chen, Peng Hu, Wei Ming, Yang Zhang, Lijian Lin, Tsung-Hsien Chigrinov, Vladimir Lu, Yan-Qing National Laboratory of Solid State Microstructures College of Engineering and Applied Sciences Nanjing University Nanjing 210093 China Department of Photonics National Sun Yat-sen University Kaohsiung 80424 Taiwan Center for Display Research Department of Electronic and Computer Engineering Hong Kong University of Science and Technology Kowloon Hong Kong

Optical beam shaping plays a key role in optics and photonics. In this work, meta-q-plate featured by arbitrarily space-variant optical axes is proposed and demonstrated via liquid crystal photoalignment based on a polarization-sensitive alignment agent and a dynamic micro-lithography system. Metaq-plates with multiple-, azimuthally/radially variant topological charges and initial azimuthal angles are fabricated. Accordingly, complex beams with elliptical, asymmetrical, multi-ringed and hurricane transverse profiles are generated, making the manipulation of optical vortex up to an unprecedented flexibility. The evolution, handedness and Michelson interferogram of the hurricane one are theoretically analysed and experimentally verified. The design facilitates the manipulation of polarization and spatial degrees of freedom of light in a point-to-point manner. The realization of metaq-plate drastically enhances the capability of beam shaping and may pave a bright way towards optical manipulations, OAM based informatics, quantum optics and other fields.

A vector matroid-theoretic approach in the study of structural controllability over F(z)

In this paper, the structural controllability of the systems over F(z) is studied using a new mathematical method-matroids. Firstly, a vector matroid is defined over F(z). Secondly, the full rank conditions of [sI - A| B] (s∊℘) are derived in terms of the concept related to matroid theory, such as rank, base and union. Then the sufficient condition for the linear system and composite system over F(z) to be structurally controllable is obtained. Finally, this paper gives several examples to demonstrate that the married-theoretic approach is simpler than other existing approaches. Copyright © 2017, The Authors. All rights reserved.

This paper presents a search for new heavy particles decaying into a pair of top quarks using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector at the Large Hadron Collider. The search is performed using events consistent with pair production of high-transverse-momentum top quarks and their subsequent decays into the fully hadronic final states. The analysis is optimized for resonances decaying into a $$ t\overline{t} $$ pair with mass above 1.4 TeV, exploiting a dedicated multivariate technique with jet substructure to identify hadronically decaying top quarks using large-radius jets and evaluating the background expectation from data. No significant deviation from the background prediction is observed. Limits are set on the production cross-section times branching fraction for the new Z′ boson in a topcolor-assisted-technicolor model. The Z′ boson masses below 3.9 and 4.7 TeV are excluded at 95% confidence level for the decay widths of 1% and 3%, respectively.

Analysis on Cracked Commuter Aircraft Wing Under Dynamic Cruise Load By Means of XFEM

Journal of Physics: Conference Series 2018年第1期1106卷

作者： N Wirawan N A Abdullah Mahesa Akbar J L Curiel-Sosa Aeronautics Technology Center National Institute of Aeronautics and Space of Indonesia (LAPAN) Bogor Indonesia Department of Mechanical Engineering Computer-Aided Aerospace and Mechanical Engineering Research Group (CA2M) The University of Sheffield The Portobello Centre Sheffield S1 4ET United Kingdom Department of Mechanical Engineering International Islamic University Malaysia Malaysia

In this paper, a new investigation of crack propagation on a commuter aircraft wing is discussed. The aircraft is a 19-seater multi-purpose commuter aircraft designed for a mission on the remote area. The dynamic load acting on the wing is assumed as harmonic load considering aerodynamic lift at a particular excitation frequency. A 3D wingbox CAD model is developed for the numerical simulation. Extended finite element (XFEM) is applied to analyse the crack propagation on the aircraft wing. The crack growth simulation is successfully done, and the results are shown in some details. These results provided a novel insight on the computational simulation of cracked wing structure under dynamic flight load.
