Trajectory planning has been a common and important topic in robotics since its generation. As a powerful tool, it can enhance the performance of the robots in manufacturing industry. In this paper, a trajectory planning method based on unit quaternion was proposed. Unit quaternions were used to represent the orientations of the target as there are no more singularities. The trajectory was planning...
Most existing path planning algorithms focus on generating piecewise linear functions, while the smoothness of the path is usually ignored. Route stability and energy saving are key issues for an autonomous underwater vehicle (AUV) working in the underwater environment. To ensure that AUV can pass through the target area steadily and safely, a path smoother is required. This paper puts forward a novel...
With the air fight environment getting more and more complex, the anti-jamming performance of active radar guided air-to-air missile (ARGAAM) is noticed by all countries worldwide. This paper develops a new method to plan the anti-jamming performance test for ARGAAM characteristic. The method plans the missile anti-jamming performance test by flight test and digital simulation. Finally, the anti-jamming...
Model checking provides a way to automatically verify hardware and software systems, whereas the goal of planning is to produce a sequence of actions that leads from the initial state to the desired goal states. Recent research indicates that there is a strong connection between model checking and planning problem solving. In this paper, we investigate the feasibility of using different model checking...
Graph theory is introduced into the contact structure of power supply block which is based on topological connection between substations. According to the basic principles of constructing power block contact models, four typical power block contact models with any number of interconnected substations are constructed. On this basis, the structural characteristic indexes of power block contact models...
Model checking provides a way to automatically verify hardware and software systems, whereas the goal of planning is to produce a sequence of actions that leads from the initial state to the desired goal state. Recently research indicates that there is a strong connection between model checking and planning problem solving. In this paper, we investigate the feasibility of using a newly developed model...
The paper investigates and analyzes the relationship between metacognitive strategies and their English capabilities of 90 sophomores of English majors in the writing of English as a second language based on multimedia technology. Quantitative researches are involved in the investigation and the result shows that the frequencies of the subjects' metacognitive strategies in fundamental English writing...
In connection with the problem of hull blocks virtual assembly sequence planning. Improved genetic algorithm is proposed to be applied. In connection with multi-layer assembly structure of hull blocks, Hierarchical optimization method is proposed to solve the problem. The optimal solution is always lost in the iteration process when Traditional genetic algorithm is applied, the problem could be solved...
Based on the mobile robot dynamic characteristics of the working environment, this paper presents a model based on classic artificial potential field potential field on the basis of considering dynamic model of velocity potential field, using quantum particle swarm optimization algorithm, using quantum particle swarm optimization algorithm for rapid global search and artificial potential field operations,...
ArcGIS Geoprocessing is an important part of ArcGIS, which is a large-scale geographic information system software launched by ESRI corporation. The ArcGIS Geoprocessing provides an application-oriented and Process-oriented spatial analysis modeling method, so it's a very useful assistant decision-making and programming tools. Project Site location is a typical multifactor comprehensive evaluation...
Enterprise Resource Planning (ERP) projects have often been found to be costly, complex, and risky to implement in enterprises. Therefore, understanding ERP implementation risks can help reduce the failure of ERP projects. The aim of this study was to explore two questions: (1) Do the six risk dimensions (planning & control, requirement, organization environment, user, team, and project complex)...
The pollution discharge amount of 15 rivers flowing into Taihu Lake in Suzhou, Wuxi and Changzhou of Jiangsu Province, China are examined based on 2007 general survey of pollution sources, statistical yearbook and the data from some related departments. Pollutant emission is large, dominantly from domestic source and secondarily from industrial and agricultural pollution. Comparison of discharge amount...
Software Engineering is a comprehensive and highly practical course, traditional teaching is very inadequate. This paper further research teaching reform and practice on the Software Engineering course. We proposed that concept maps can be employed to the software engineering teaching. The role and the application approach of concept map are explored. And we introduce our practice teaching reform...
In multi-agent system (MAS), exception handling is a complex problem due to distributed and decentralized nature of data and control in such systems. The agent has some uncertainties because of its autonomy, which increases the issue of handle exception. This paper begins with the concept of cooperation among agents and the organization of agents in the MAS, based on which a domain-independent exception...
Software engineering is a comprehensive and highly practical course, traditional teaching is very inadequate. Concept maps are a way to develop logical thinking and study skills, by revealing connections and helping students see how individual ideas form a larger whole. According to its characters concept maps should be used to improve software engineering teaching. In recent years both research and...
The problem how to evaluate the provided alternatives and determine a suitable one does exist in the process of distribution network planning. On the basis of the existing methods of multi-attribute decision-making (MADA) and combining non-linear programming with the theory of combination evaluation, this paper for the first time constructs an MADA system based on combination evaluation method for...
