In modern information warfare, the traditional management and utilization of sensor resources is difficult to meet with the intelligent and high-efficient requirement of naval fleet. Considering the characteristics of intelligence, reconnaissance and surveillance (ISR) mission, a mission-oriented ISR task planning model and method for Naval Fleet is presented. Based on the hierarchical analysis method,...
Many theoretic approaches for feedback stabilization control of nonholonomic mobile robots cannot be directly applied to practical robots since various kinematic constraints such as the velocity and acceleration limits are not considered in existing methods. To deal with this issue, we aim to propose a generic approach which first uses an (arbitrary) feedback stabilizer to generate the ‘path’ and...
Dose calculation is critical important for the radiotherapy of cancer treatment. In this paper, an efficient Monte-Carlo radiation dose calculation system is presented. The dose calculation kernel of our system is based on the DPM algorithm [12]. The original codes are replanted into windows environment and rewritten using C++. Optimization techniques are applied to achieve a higher performance. Experimental...
This research investigated the influence of individual characteristics and the built environment on grocery shopping destination choice in the Seattle-King County Area. Four binary logistic models served to estimate the impact of individual characteristics and built environments on grocery shopping destination choice. The results showed that the respondents' attitudes toward food and the individual...
Aim at the problem that the variation of constraint leads to variation of assembly sequence, this paper presents a method based on the gray theory associated with genetic algorithm (GA). The variation of constraint on assembly site for complex products includes absence of parts, fixtures, resource and so on. Firstly, a seven-cell coding format is built based on multiple genes. The fitness function...
Based on the statistical analysis on the emission of PM10 from different air pollution sources, ADMS-Urban was used to simulate the concentration distribution of PM10 in Shanghai Expo area. Typical days were chosen to study the distribution of PM10 in Expo planning area and influencing factors were analyzed. The results showed that Yangshupu power plant polluted Expo planning area most seriously,...
To the problem of standoff Ground Moving Target Tracking using a fixed-wing UAV, a novel solving framework is presented, which based on target state estimation, prediction and on-line motion planning. First of all, a solving framework was presented, the formal representation and system model of standoff tracking using Fixed-wing UAV was established; next, the Unscented Kalman Filter was suggested...
Based on the statistical analysis on the emission of main air pollutants, ADMS-Urban was used to simulate the concentration distribution of main pollutants in Shanghai Expo planning area. Typical days were chosen to study the distribution of the main pollutants in Expo planning area and influencing factors were analyzed. The results showed that Yangshupu power plant polluted Expo planning area most...
In this paper, an attempt is made to define the features of SAR employment planning problem for tactical aircraft in military operations. General concepts for use of airborne SAR to find and locate targets are described and formulated into a parameter optimization problem. The utility and constrains of SAR imaging followed by weapon delivery are described, which rely on target characteristics, threat...
Based on the statistical analysis on the emission of main air pollution sources, ADMS-Urban was used to simulate the distribution of SO2 concentration in the Shanghai Expo area. The effects of wind direction, wind speed, clouds coverage and rainfall on the emission of SO2 concentration were investigated. The results show that the Yangshupu power plant gave the most contribution to SO2 concentration...
This paper proposes an optimal Var resource allocation framework for power transmission system in such a manner that both voltage profile and security margin for future operation is considered. The risk index is used to represent the uncertainty in this framework. The conception of Var gap is proposed to cover the voltage profile issue and the security margin issue when the Var allocation is performed...
We propose a general structure of Benders decomposition for power system decision making. In this framework, three elements of decision-making problems in power systems are mapped into the three types of subproblems of the Benders decomposition approach. An information communication strategy is introduced. We also explain how the approach facilitates the unbundling of computational services.
In this paper, a systematic risk-based transmission line expansion approach is studied. The approach addresses three objectives: load-driven expansion, security-enhancement expansion and risk-based expansion. The first problem identifies transmission expansions necessary to correct inadequacy; the second problem identifies transmission expansion necessary to correct insecurity; the third problem balances...
