This paper studies of the theoretical and practical application of the Automatic Throttle Control System from the perspective of System Dynamic Theory. Through the simulation of a flying vehicle in a state of automatic approach, we show the design thought and the importance of the Automatic Throttle Control System.
In recent years, some researchers introduce the resource allocation into the MIMO (Multiple Input Multiple Output) radar, the concept of which has been proposed for about 10 years. In this paper, we firstly analyze the signal model in MIMO radar and the influence of resource allocation on multiple targets localization; then we review the present research on resource allocation in MIMO radar briefly,...
The development of image processing methods based on partial differential equations, such as denoising, restoration, segmentation and so on, is an emerging field in the last decade, where a large number of models are second order nonlinear diffusion equations. In this article, we present a two level finite volume method to solve the Perona and Malik (P-M) equation. The method involves solving one...
Reliability analysis based on failure mechanism takes advantage of unnecessary requirement for the field data, compared with the traditional method based on probability statistics. Current reliability analysis for systems based on failure dependence mainly focus their views on either failure level or failure process level, but barely from the aspect of failure mechanism. Our previous work used Mechanism...
Matrix factorization is a key component of collaborative filtering-based recommendation systems because it allows us to complete sparse user-by-item ratings matrices under a low-rank assumption that encodes the belief that similar users give similar ratings and that similar items garner similar ratings. This paradigm has had immeasurable practical success, but it is not the complete story for understanding...
A moving target creates the Doppler effect on the transmitted signal, which can be exploited to improve the target localization accuracy in multistatic sonar that normally utilizes differential delay time measurements only. In this letter, we first examine the contribution of Doppler measurements via the Cr $\acute{\text{a}}$mer–Rao lower bound (CRLB) study, and then develop an algebraic closed-form...
There are low power density electromagnetic (EM) waves everywhere in our environment due to the development of various wireless communication technologies, such as TV, radio, cellular, WLAN and Wi-Fi, etc.. It can be used for energy saving to harvest the electromagnetic energy for powering up electronic devices, such as RFID tags and sensors. In this paper, we present a high gain and miniatured receiving...
In this paper, we propose a simple and full-solution polymethylmethacrylate (PMMA)-assisted spin-coating method to produce silver nanowire (Ag NW) networks on both rigid and flexible substrates as transparent electrodes. Because of the high viscosity of PMMA, Ag NWs embedded in it can be distributed uniformly over a large area. Thus, through this method, transparent electrodes with high optical transmittance...
We propose and numerically demonstrate a novel hot-carrier solar cell based on plasmonic nanofocusing. It consists of a gold-coated titanium dioxide nanowires with a cone on the top and a bottom gold film. The ultra-broadband absorption is mainly due to the high light coupling efficiency induced by the gradual openings between the cones and the strong plasmonic nanofocusing effects induced by the...
The researches and applications of project post-assessment of investment projects attract more and more attention in China, which is important for constructing a harmonious society and meet the need of sustainable development. In this paper, project post-assessment of Tashan mine is done by using the causal methods and means of before-after contrast. At first, the development of project post-assessment...
Nowadays, there are more and more hybrid apps appearing in the app market which contain native code and Web pages. In order to enhance the ability of JavaScript in the WebView, these apps expose methods that can be invoked by JavaScript. However, when we study the communication from JavaScript to native code, we find a security issue that if the exposed methods finally invoke sensitive methods, such...
Generator dynamic simulation physical was set up with SIMPACK multi-body dynamics software. Non-linear feature of bearing and the influence of elastic support on generator were researched. Results showed that the alteration of bearing stiffness would significantly change the natural frequency of the generator rotor, and may cause resonance with power grid. The variation of the elastic support stiffness...
In this paper, a wideband substrate integrated waveguide (SIW) horn antenna with enhanced performance is investigated. Through adding metallic via on the edge of the parallel plates, additional inductance is introduced and can compensate the coupling capacitance in some degree, which significantly improves the impedance matching of the planar horn antenna. Moreover, the introduced via act as the extended...
In this paper, we propose a novel graph kernel specifically to address a challenging problem in the field of cyber-security, namely, malware detection. Previous research has revealed the following: (1) Graph representations of programs are ideally suited for malware detection as they are robust against several attacks, (2) Besides capturing topological neighbourhoods (i.e., structural information)...
Here three subwavelength multiband receiving antennas have been designed using corrugated ring resonator printed on a thin dielectric substrate with spiral-shaped defect ground structure (DGS). Numerical simulations verified that these multiband antennas have multiband with a small size of only 0.1λ*0.1λ. In addition, a 2*2 antenna array has been proposed and numerically demonstrated that the gain...
A measurement-based voltage stability assessment and closed-loop control strategy is proposed and demonstrated on the Center for Ultra-Wide-Area Resilient Electric Energy Transmission Networks (CURENT) Hardware Test Bed (HTB) system, a power electronic converter-based research and experiment platform. This new strategy is based on an N+1 buses equivalent proposed recently by Ref. [1] for calculating...
It is well-known that malware constantly evolves so as to evade detection and this causes the entire malware population to be non-stationary. Contrary to this fact, prior works on machine learning based Android malware detection have assumed that the distribution of the observed malware characteristics (i.e., features) do not change over time. In this work, we address the problem of malware population...
Ambisonics is a series of spatial sound reproduction system with flexible number of loudspeakers. Based on spatial harmonics decomposition and truncation at various orders, it aims at approximate reconstruction of target sound field within a certain region and below a certain frequency limit. The region and frequency limit are determined by spatial sampling theorem of sound field. The present work...
Ambisonics is a series of flexible spatial sound systems based on spatial harmonics decomposition of sound field. It is able to reconstruct sound field accurately within some region and below some frequency limit which are imposed by Shannon-Nyquist spatial sampling theorem and determined by the order of Ambisonics. Above the Shannon-Nyquist limit of spatial sampling, errors occur in the reconstructed...
In this paper, we address blind separation of spatially correlated signals mixed by multiple-input multiple-output (MIMO) finite-impulse-response (FIR) systems. We propose to first preprocess the source signals using precoders in transmitters and then the coded signals are transmitted. On the receiving side, the Z-domain features of the precoders are exploited to separate the coded signals, from which...
