In this paper, we focus on the control of triangular multi-agent formations with hybrid communication topology though distance-based approach. By saying hybrid topology, we mean that the communication topology contains both undirected and directed links, or in other words, the underlying graph of the formation contains both undirected and directed edges. A new type of graph, namely hybrid graph, is...
The common defect types and signal characteristics of the steel pipe are introduced, the time-frequency analysis is applied to the signal, experiment results are consistence with simulation results. Inner burr model is constructed to analysis the signal characteristic of various burrs. The ensemble empirical mode decomposition (EEMD) method and wavelet packet analysis are used for the adaptive decomposition...
Community structure is one of the most important features of real networks and it can reveal the internal organization of the nodes. The classical GN algorithm obtains communities by iterative computation of global betweenness in a social network so it can only get a course-grained community partition. In this paper we proposed Co-game, a community overlapping detection algorithm based on game theory...
A liquid level sensor based on a fiber Bragg grating (FBG) assisted by a section of multimode fiber core (MMFC) was demonstrated. Since the coupling coefficients between the MMFC and the single-mode fiber changes and FBG reflection modes keep still as surrounding liquid level varying, the liquid level can be determined by measuring the power of the FBG reflection core mode. Experimental results show...
Social emotion analysis of online users has become an important task for mining public opinions, which aims at detecting the readers' emotions evoked by online news articles. In this paper, we focus on building a social emotion analysis system (SEAS) for online news. The system has implemented a text data crawler for mainstream online news websites, the modules of document preprocessing, document...
With the rapid growth of social media and online news services, users nowadays can respond to online news by rating subjective emotions such as happiness, surprise or anger actively. Once the user ratings is over a certain range, it begins to show up a tendency of what most people think and feel, which can help us understand the preferences and perspectives of most users, and help news providers to...
In order to complete a service task more efficiently, robot needs to create a map quickly and recognize objects during this process. In this paper, a novel mapping method is proposed to address this problem. Firstly, Admissible Space Tree is generated to acquire possible node. Then, immune algorithm is applied for its advantages such as diversity, dynamic, parallel management and self-adaptation....
Application performance monitoring and analyzing system has been widely used in online applications and services, to obtain high performance and reliability. However, existing performance monitoring systems only raise an alarm when certain parameter exceeds its threshold and do not provide further analysis. This paper presents an application performance monitoring and analyzing model based on Bayesian...
Twitter presents a nice opportunity for targeting advertisements that are contextually related to Twitter content. By virtue of the sparse and noisy text makes identifying the tweets for advertising a very hard problem. In this paper, we propose a novel and effective scheme to identify the tweets that can be targeted for advertisements. We firstly construct a multi-source corpus to collect more auxiliary...
In this paper, a vision-based human tracking approach integrating Histogram of Oriented Gradient (HOG) and Hu moment feature is presented under the Particle Filter framework. Our motivation stems from the fact that traditional Particle Filter (PF) based on single feature is not robust when the background color, illuminate and target deformation change, and it may lead to lose target or fail to detect...
This paper presents a hierarchical method of region division for mobile robot system based on spectral clustering algorithm. Firstly, to improve the exploration efficiency, topological map is constructed incrementally using a hybrid map model with grid-topplogy structure. And then, topology-based Voronoi Diagram is introduced to divide the map and express the whole environment uniquely. Meanwhile,...
In the Internet of Things (IoT), we all are ``things''. Graph theory, a branch of discrete mathematics, has been proven to be useful and powerful in understanding complex networks in history. By means of graph theory, we define new concepts and terminology, and explore the definition of IoT, and then show that IoT is the union of a topological network, a data-functional network and a domi-functional...
In the microwave system it is very important to the manufacture of MEMS microstrip array antennas, microstrip array antenna's geometrical parameters are closely related to its electrical parameters. In the manufacturing process of MEMS, it is very difficult to measure the geometry parameters. However, currently it is easy to test the electrical parameters of microwave systems. The real geometry parameters...
Surface water quality in rural areas usually has a great variation in China and is hard to charaterize by classical statistic methods. In this paper, a fuzzy c-means clustering method is used to classify and assess rural surface water quality based on the monitoring data from 33 typical stations in 23 rural rivers and 4 reservoirs in Lianyungang city. The results show that the 33 monitoring stations...
In this paper, we present a monocular vision tracking approach based on Hu moment recognition in Particle Filter framework. Our motivation stems from the fact that when the target rotates, translates and scales, target losing or mistracking always happens in image. To solve this problem, we propose an object tracking technique based on Particle Filter and Hu moment by using monocular vision method...
How to tackle the difficulty involved in optical flow calculation caused by illumination inconsistency in adjacent video frames remains an open challenge. This motivates us to investigate how to obtain a valid and accurate optical flow field which is robust to illumination change based on structure-texture decomposition. In this paper, we attempt to reveal the involved technique details in this ROF...
Transient electromagnetic scattering from object composed of conductor and dielectric material is analyzed by the marching-on-in-degree (MOD) time-domain integral equation (TDIE) method. Weighted Laguerre polynomials are exploited as the entire domain temporal basis functions, and lead to unconditionally stable solution. Besides, the curvilinear RWG spatial basis functions decrease the number of unknowns...
The adsorption behavior of Cr3+ and Fe3+ on 001×7 strong-acid cation exchange resin was studied with the static method, respectively getting Adsorption Isotherms of Resin 001×7 for Cr3+ and Fe3+. The experimental results show that, in the studied concentration range, the equilibrium adsorption data of Cr3+ fit to Langmiur isotherms, while Fe3+ fitting to Frendlich isotherms. Kinetic analysis show...
Silver sillago is one of the commercially important fish species in China. Protein properties and lipid profiles were evaluated. It is a good source of protein, consisting of 46.98% myofibrillar protein, 20.74% sarcoplasmic protein, 24.70% alkali soluble protein and 6.91% Stroma protein. The major sarcoplasmic proteins exhibited molecular weights of 27, 31, 34, 36, 38, 43, 49, 61 and 98 kDa, and SSP...
