We study experimentally and theoretically the use of photonic crystal nano-cavity to generate a broad range of waveforms, mediating by Drude electron-hole plasma in silicon, and coming from the dynamical states at varying operating conditions.
This paper designs a multifunctional remote-controllable home system based load aggregation management system. On the one hand, this system combines the Load Aggregators with Smart Home and presents an effective and practical method to realize household load management. When the household loads are needed to adjust by load aggregators, the system can automatically control the load on the user side...
In this paper, a low coupled, colocated orthogonal dual-polarized MIMO antenna consisting of a loop and a coplanar dipole is presented. To reduce the high mutual coupling between the two antennas, some electromagnetic band gap (EBG) material was used. Simulation results show that the mutual coupling between the coplanar loop and dipole can be effectively reduced, from −6 dB without EBG to −30 dB with...
Nowadays, QR (quick-response) codes have become part of our daily life. In many applications, QR codes are posted (i.e. pasted or printed) on cylinders. Then, the QR image as captured by a camera would be distorted. In this paper, we try to tackle the decoding of QR codes in such a situation. It is based on perspective projection (PP), which is specified by a camera matrix (cM), with the assistance...
At present, voltage regulation of no load distribution transformer is not flexible and failure rate of mechanical on-load tap-changers is high. To solve these problems, a scheme of automatic on-load voltage regulation system designed via thyristor for distribution transformer was proposed. The system improved the existing topology of on-load voltage regulation system via power electronic device and...
In this study, new isotropic magnetic membrane-type actuators are fabricated and characterized by both theoretical and experimental approaches in terms of their deflections and delivered actuation forces when an external magnetic field is applied. The effects of diameter, thickness, concentration of magnetic particles are investigated. The actuation force depends on the amount of magnetic substance...
The analysis of multiple Android malware families indicates malware instances within a common malware family always have similar call graph structures. Based on the isomorphism of sensitive API call graph, we propose a method which is used to construct malware family features via combining static analysis approach with graph similarity metric. The experiment is performed on a malware dataset which...
In this paper, decision theory is introduced to key performance indicator (KPI) related process monitoring and fault diagnosis (PM-FD) field in order to settle the difficulties of making the most rational decision among several candidates. Considering that there are several evaluation criteria for PM-FD approaches, this paper provides some methods to help decision makers to find the most effective...
Binocular stereoscopic vision system of underwater vehicle plays an important role in promoting the exploration and development of the marine environment. In order to realize the underwater autonomous grasping task based on visual servoing, this paper studied binocular vision ranging technology of underwater vehicle and vision control technology of manipulator. By adjusting the placement and pose...
Quality of service (QoS) constrained multicast service over vehicular networks has considerable benefit for both road safety and entertainment, while the resource allocation problem of it is challenging due to the high mobility of vehicles. In this paper, we manage the vehicle mobility by dividing one scheduling round into multiple segments, and investigate the resource allocation problem to answer...
Most FPGAs use Look-Up Table (LUT) as the basic logic block. Input sharing look-up table (ISLUT) architecture is a cluster architecture, which can be configured as one 6-input LUT, two smaller LUTs or other modes. In this paper, several ISLUT architectures are added into Verilog-to-Routing (VTR) tool to compare with standard 6-input basic logic element (BLE6) architecture. Experimental results show...
A novel method for fault location is proposed in this paper, which is based on fault voltages and currents sampled synchronously on both ends of the fault line. This algorithm is based on precise integration. Using the synchronous measurement data at the ends of the fault line, it computes the voltage along transmission line. Then comparing two groups of voltage, it can find out the location of trouble...
Existing loop vectorization techniques can exploit either intra-or inter-iteration SIMD parallelism alone in a code region if one part of the region vectorized for one type of parallelism has data dependences (called mixed-parallelism-inhibiting dependences) on the other part of the region vectorized for the other type of parallelism. In this paper, we consider a class of loops that exhibit both types...
Natural disasters can result in severe damage to communication infrastructure, which leads to further chaos to the damaged area. After the disaster strikes, most of the victims would gather at the evacuation sites for food supplies and other necessities. Having a good communication network is very important to help the victims. In this paper, we aim at recovering the network from the still-alive mobile...
A binarization method for image enhancement of the palm leaf manuscripts is proposed, which can effectively perform the image binarization as well as remove superfluous lines on the images of palm leaf manuscripts. Firstly, an improved background elimination method is presented to solve the problem caused by different background color in a palm leaf. Then the classical Niblack's method is used to...
The vast majority of nonuniform transmission lines are no analytical solution except for a few special forms of transmission line. Dividing nonuniform transmission line into several equal parts, then each part can be regarded as uniform transmission line approximately. Using the theory of uniform transmission line to analyze nonuniform transmission line's transient response is the commonly used method...
Image segmentation is a key point for analyzing and understanding image, which occupies an important position in image processing. Recent studies have attempted to tackle pixel level labeling tasks using deep learning. In our paper, we propose an approach of combining fully convolutional network and conditional random field for image semantic segmentation. We utilize FCN model to automatically learn...
In recent years, plenty of studies endeavor to analyze the life auditory scenarios via mining non-speech sounds. Conventional audio recognition schemes clearly bound the feature extraction and recognition stages, such as in speech recognition. However, such separation leads to inconsistency in the purposes at each stage. The recognition stage contributes to portray the global data distribution focusing...
Tree traversals are widely used irregular applications. Given a tree traversal algorithm, where a single tree is traversed by multiple queries (with truncation), its efficient parallelization on GPUs is hindered by branch divergence, load imbalance and memory-access irregularity, as the nodes and their visitation orders differ greatly under different queries. We leverage a key insight made on several...
This paper studies the optimization problem of agile-turn for the vertically launched missiles. The objective of this problem is to minimize the flight range. Compared with the previous studies, there are three major difficulties in solving this problem: (1) the problem is based on the six-degree-of-freedom dynamic model; (2) Due to the large angle attitude maneuvers, there exists singularity phenomenon...
