This paper presents a novel extended multi-structure local binary pattern (EMSLBP) approach for high-resolution image classification, generalizing the well-known local binary pattern (LBP) approach. In the proposed EMSLBP approach, three-coupled descriptors with multi-structure sampling are proposed to extract complementary features (pixel value and radial difference) from local image patches. The...
The thermal plume discharged from the power plants has exerted many negative effects on the coastal environment by decreasing the dissolved oxygen, density and viscosity of water, speeding up the settlement of suspended mater, and changing the habit of life, growth and reproduction of marine organisms. To monitor the thermal pollution of cooling-water discharge from the coal-fired power plants and...
With the increasing amount of Automatic Identification System, AIS data, an effective analysis method and technology for large-scale data are a challenge. Information visualization is a suitable technology for people without professional data mining knowledge, such as navigation managers and ship drivers, for understanding mass AIS data. We implement direct and summary visualization of AIS information...
This paper presents a method of video shot motion analysis based on LK optical flow method to solve the problem of film video shot motion of visual comfortable effect. A segmentation method based on footage of two class support vector machine classification is used. The optical flow method based on the hierarchical Lucas-Kanade in Pyramid combined with SLAM Algorithm to extract the motion information...
With the popularization of large-complex machinery, the maintenance personnel demand of such equipment is growing as well. Traditional way of training equipment maintenance means large cost of space and funds. We design an equipment maintenance training system based on Web3D technology. Compared with the traditional way, the virtual maintenance teaching system based on virtual reality technology can...
Four LTE low-band MIMO antennas in the smartphone for applications in the 4 × 4 MIMO system are presented. The four antennas are based on the open-slot antenna structure and disposed along the short edges and the side edges of the smartphone. The two short-edge antennas cover 698∼960 MHz. The two side-edge antennas cover 824∼960 MHz. The four antennas can be applied in a 4 × 4 LTE MIMO operation in...
Distributed cache is capable of accelerating the process of retrieving an enormous amount of data. In order to optimize the cache performance in distributed environment, we present an architecture of cache replacement algorithms. The architecture called HQ (Hybrid Queue) focuses on organizing distributed cache clusters hierarchically, making use of the web data distribution. In addition, we also introduce...
A satisfactory cross-border logistics service (CBLS) can help promote business activities in cross-border e-commerce. Kansei engineering (KE) is an approach to design the elements which satisfy customers' affective and emotional perceptions into services and products. In this study, the KE approach is applied to derive ideas for the development of CBLS. For this purpose, Partial Least Squares (PLS)...
Since a large proportion of pixels are often composed of mixed land cover types within remote sensing images, how to eliminate the impact of the error resulting from pixel mixing effect in the estimation of land surface emissivity on the accuracy of land surface temperature (LST) retrieval from remote sensing data is a key problem to resolve firstly in process of LST retrieval. Based on the local...
This paper is aimed to improve the achievable relativity stability via a relaxed saturation constraint approach. Specifically, two control laws are designed in advance, one is constructed from a nominal saturation constraint, and another is obtained from a relaxed saturation constraint with an obtainable larger relative stability. During system operation, the actual controller is scheduled between...
We propose a non-Hermitian symmetry orthogonal frequency division multiplexing (NHS-OFDM) scheme for indoor space division multiplexing based visible light communication (SDM-VLC) systems. NHS-OFDM removes the constraint of Hermitian symmetry and generates light-emitting diode (LED) compatible real-valued signals by parallelly transmitting the real (Re) part and the imaginary (Im) part of a complex-valued...
This paper proposes a robust adaptive control scheme using backstepping method with dynamic surface technique for re-entry attitude tracking control of near space hypersonic vehicle (NSHV) in the presence of model uncertainties, external disturbances and input constraints. To estimate the unknown upper bound of the compound uncertainties, the novel robust adaptive laws are designed firstly. The “explosion...
It is the first time to investigate the control problems of chaotic systems based on triangle system form. Firstly, a chaotic system can be transferred into triangle system by an appropriate coordinate transformation. Secondly, the control problems of such system: stabilization, synchronization, anti-synchronization, are studied, and the corresponding controllers are designed by the back-stepping...
We consider the optimal load-shedding problem in electric power systems where a number of transmission lines are to be taken out of service. The nonlinear power flow equations and the binary decision variables result in a mixed-integer nonlinear program. We show that the load-shedding problem has a separable structure when the power flow equation is relaxed. We exploit the separable structure by using...
The convergence analysis of two-dimensional based integrated predictive iterative learning control (2D-IPILC) is presented for batch process in presence of output noises. In the 2D-IPILC method, iterative learning control (ILC) in the batch domain is integrated reasonably with real-time model predictive control (MPC) in the time domain. Based on the 2D system theory, system response of output tracking...

It implements algorithms about target recognition, tracking, positioning based on monocular vision, etc. The hardware platform for the design is the development board by Xilinx. The system...
Short-channel gate-all-around (GAA) poly-Si junctionless (JL) nanowire (NW) transistors were fabricated using the control available through cost-effective I-Line lithographic patterning and spacer techniques. This scheme enables the production of GAA JL poly-Si NW transistors with channel length of as short as 120 nm and effective width of 49 nm, featuring significant improvement in subthreshold swing...
A black silicon solar cell fabricated using aluminum as both a catalyst and dopant is demonstrated. A nanowire/nanopyramid black silicon surface texture is grown via aluminum (Al)-catalyzed vapor-liquid-solid growth, and post-growth annealing diffuses the aluminum into the n-type substrate, forming a p-n junction. Devices with nanopyramid surface textures are found to have higher short-circuit currents...
For practical automated manufacturing systems, supervisory control techniques (SCTs) are of great significance and should be integrated in their plant models. SCTs are frequently accompanied by supervisor simplification issues. In the past, it is taken for granted that supervisor simplification is associated with systems' structure, because most simplification techniques are based on structure analysis...
In D2D communication, power allocation is important due to interference among D2D users. In this paper, we model the power allocation problem in D2D environment as a stochastic game and find the Nash equilibrium. The simulation shows the workability and correctness of the proposed stochastic power allocation game.
