Aimed at the problem of the noise in the side channel analysis (SCA) of hardware Trojan, a novel idea to develop an optimal algorithm model based on smooth filtering is discussed in this paper. To reduce the influence of the abnormal points on the curve, the idea uses the least square method to fit the original data curve. The approach is validated using power simulation with a 128-bit Advanced Encryption...
The traditional artificial cigarette review methods are difficult to match the high-speed automatic cigarette sorting system. In this paper, a new cigarette recognition method using the uniqueness of cigarette bar codes was proposed. Firstly, a binary image filtering algorithm based on square adaptive structure element of mathematical morphology (SASEMM) was used to get several potential sub-regions,...
In modern electronic countermeasures, in order to interfere the normal work of reconnaissance receiver, the electronic jammer is usually used. For the wideband noise signal emitted by the jammer, the novel direction finding and localization algorithms are presented. In the direction finding(DF) algorithm, the time delay estimation is converted to the frequency estimation. The algorithm is not limited...
In this paper, a novel DOA matrix method based on first order statistics is proposed, which can estimate two-dimensional (2-D) direction of arrival (DOA) for coherent signals at the cost of less computational complexity. Firstly, the pseudo autocovariance matrix and pseudo cross covariance matrix are constructed by the first order statistics of array received data, and the rank of the matrix is proved...
The research on community structure is a key to analyze the network functionality and topology, and thus it is significant to detect and analysis the community structure. During the abstract process from an actual system to a network, especially for a large-scale network, it is inevitable to have mistaken connections between nodes or have connection missing. In addition, in real applications, from...
Wireless capsule endoscopy (WCE) is a new innovative solution for gastrointestinal disease detection. The image quality of WCE is not satisfactory for medical applications since some of them are dark and low-contrast. The WCE image enhancement is a challenge task, mainly because the diversity of the WCE images of different people and the need to preserve the local fine details of WCE images. Hence,...
Implementation-efficient nonlinear mitigation algorithms for digital coherent transceivers are introduced. Q-improvement by different algorithm combinations is presented for different transmission scenarios.

Support vector machine (SVM) is an effective method for resolving regression problem. However, tradition SVM is very sensitive to noises in the training sample. In order to overcome this problem, fuzzy support vector regression (FSVR) based on combining cluster center with affinity is proposed in this paper. The fuzzy membership is defined not only by the distance between a point and its cluster center,...
Harmonic estimation of a signal disturbance with additive noise has been an area of interest for researchers in many science and engineering. In this paper, a new technique which can estimate harmonic based on Particle Swarm Optimization (PSO) is presented. Its fundamental idea is to simulate the behavior of the swarm in nature to construct the stochastic optimization algorithm. The identification...
System on package (SOP) is an emerging technology, and provides an implementation options for system with small size, especially for mixed-signal systems. However, in such a compact package, noise generated by the digital chip can be easily coupled to the RF IC, and degrade the sensitivity of RF signal. In this paper, a simple and efficient multi-order lowpass filter for EMI and SSN suppression in...
For the error problem of the data processing in dynamic weighing system at present, our experiment takes two-axle vehicle and truck as the object. The collected data by singular spectrum analysis (SSA) algorithm is under preprocessing, then the peak values of the front and rear axle, the ascending slope and descending slope on the weigh-bridge, speed and type of vehicles, is used as input of the Learning...
Ground bounce noise (GBN) is becoming one of the major challenges for designing high speed system and packages. It causes serious signal integrity (SI) problems in the high speed system. Traditional techniques center on adding more decoupling capacitors to create a low impedance path. Electromagnetic band gap (EBG) structure is used to suppress GBN combined with decoupling capacitors in this study...
Simultaneous switching noise (SSN) and its behavior have recently become more and more critical in IC and other highspeed system designs [1][2]. This is attributed to ever-increasing speed, frequency, density, and power, as well as decreasing circuit dimensions and logic levels. The difference in a few mill volts may cause the system to fail. Therefore, it is very important to understand the characteristics...

Because of many duplicated web pages existing on the web, search engines need to find and remove them, not only for saving process time and hardware resource, but also for ensuring that users can get the result information without many replicas. In this paper, we propose a method to find and remove duplicated Chinese Web pages for search engine. First we describe a scheme based on semantic keywords...
