Data-oriented is a new and applied theory which provides methods that models the concepts with data structures. If the concept is modeled by using sufficient data in modeling, the required inferences and calculations can be done fast and less complexity. In this paper a data-oriented model of exponential random variable by using probability tree is introduced. Digits probabilities are calculated by...
A method of multi-source SST conformance evaluation is presented in this paper, which is not only valuable for significant areas lack of site measurement but also multi-satellite remote sensing. Consensus evaluation among multi-source data is the only way to get the credibility without field measurement. A Weighted Joint Probability Distribution (WJPD) can quantify the degree of consensus among multi-source...
In this paper, we exploit the multi-modal face recognition capability by a comparative study on 8 fusion methods in the score level, including Sum, Product, Max, Min, Decision Template (DT), Dempster-Shafer Rule (DS), Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) methods. Our experiments are based on the CASIA 3D Face Database and can be divided into two modes: verification and...
In this paper, we evaluate the gender classification performance based on 3D faces according to three aspects: image resolution, data fusion and texture descriptor. Our experiments are based on CASIA 3D Face Database, which has 123 individuals in total including different expressions. Main conclusions are as follows: (1) Image resolution has little influence on the gender categorization performance,...
The traditional drought monitoring index, monthly precipitation anomaly percentage, is experimented to calculate using web-serviced remote sensing data in this paper. The Tropical Rainfall Measuring Mission (TRMM) monthly precipitation rate products are puplished by Goddard Space Flight Center in internet, all products can be downloaded freely. First, the monthly rainfall of China in July and August...
The reduced model of mini unmanned helicopter in hover is proposed in this paper. A specific analysis for the dynamic characteristics of mini unmanned helicopter is given. Based on the analysed results, we carry on a very thorough trim computing process under the condition that the mini unmanned helicopter stays in hover. We can use the 6-DOF rigid body equations of motion to establish a full state...
As a kind of fluid delivering device, micropumps usually employ flexible structure such as flexible membrane to force fluid flowing. It is necessary to predict the motion of flexible structure so as to control the micropump performance. In this paper, the principle of micropump using an electrostatic actuator has been introduced. According to the thin plate elastic theory, the bending motion of electrostatic-flexible...
In this paper, we first analyzed the nano-magnetic fluid composition and properties. Then we studied the characteristics of nano-magnetic fluid magnetization and magnetization mechanism. In addition, we also studied the nano-Fe3O4 magnetic particle size and surface modification on the magnetic properties of magnetic fluids. Nano-magnetic fluid is a new type of liquid nano-composite functional material...
A new solution to vehicle routing problem (VRP) is proposed in order to overcome the disadvantages that the exact algorithms and heuristics algorithms are difficult to solve vehicle routing problem with multiple constraints. A simulation model of vehicle routing problem is built by combining the object-oriented technology and discrete event simulation technology. In this model, the events of distribution...
Facing solely demand uncertainty of market, a supplier with insufficient capital doesn't like to enter the market because of risk of the market. The supplier looks forward to choosing a retailer with sufficient capital as his partner to share the risk of market. Based on dynamic game, we demonstrate that both the supplier and the retailer's expected profit are positive when reaching Nash equilibrium...
Autonomous underwater vehicle (AUV) has been widely used in marine exploration and military applications in the past decade. The Decision-making Control System of AUV plays a key role of accomplishing its tasks in complex undersea environment. In this work a Behavior-Based Reactive Decision-making Control System is proposed for AUV. During the design of the Decision-making Control system, the hierarchy...
The method of surface geometry of object recovery mentioned in this paper can gain 3D dimensions of objects surface geometry only using a single image on the basis of brightness change. In this paper, the background knowledge and the methods related to SFS are briefly introduced. Based on the analysis and comparison of various reconstruction algorithms, this paper gives a new method of surface geometry...
This paper presents a novel and efficient algorithm for preventing the block wrongly matching in image inpainting. The proposed technique separates the inpainting process into two different and important steps. First, segment the pre-selected source area, which is called the source region, from the input image. This step can prevent the block wrongly matching effectively. Besides, the adjustment rule...
A new robust control arithmetic is put forward to deal with the uncertain attitude model of small unmanned helicopter (SUH). Firstly, the attitude matrix model of SUH is denoted by the block diagonally radioactive matrix. Secondly, based on the restriction of the closed-loop pole and variance constraints, a new robust control, which has the characteristic of system input energy limited, is put forward...
