The rapid development of aerospace technology means that the roles of space robots are becoming important. In order to reduce fuel consumption and successfully accomplish on-orbit service tasks, the base attitude disturbance should be as small as possible. When the particle swarm optimization (PSO) algorithm based trajectory planning method is applied to solve the problem, it is falling into local...
This paper presents an algorithm for triangular mesh generation from unorganized points based on 3D Delaunay tetrahedralization and mesh-growing method. This algorithm requires the point density to meet the well-sampled condition in smooth regions and dense sampling in sections of a great curvature and two close opposite surfaces. The principle of the algorithm is as follows. It begins with 3D Delaunay...
The paper mainly expands the tool soft of analog electronic experimental, it is suitable for Analog Electronic Technology Course, which is a basic course for electrical majors, for students in the future is important significance to learn professional courses. The development and use of software simulation of electronic experiment teaching has changed the experimental teaching mode that used PowerPoint...
The application of the Internet of things (IOT) in industry and mining enterprises is analyzed in this paper. A new type of IOT application layer reader with functions of RFID and data transfer by wireless sensor is designed, according to the characteristics of the Internet things of industry and mining enterprises. This reader can perceive information from people, machine and environment of industry...
A single image super resolution algorithm for license plate preprocessing is proposed in this paper. The image to be enhanced is modeled as a Markov Random Field and is estimated from the input low resolution image by image patch pairs. From the input image and the training set, observation function and compatibility function can be calculated. Then Bayesian Belief Propagation is used to select the...
Credit risk management has become a fundamental and crucial work for commercial banks. This paper studies the credit risk measurement of listed corporations by using various types of credit risk models, and analyzes their applicability in China. This paper also makes an empirical analysis to the Chinese listed corporations’ credit risk on the basis of the KMV model. Finally, several proposals on how...
Digitally controlled dc-dc converters can exhibit undesired limit-cycle oscillations due to the lack of time resolution in the digital pulse-width modulator (DPWM) to satisfy specified output voltage regulation accuracy. In this paper, the relationship between DPWM time resolution and output voltage regulation accuracy is studied for several basic converters operating in both continuous conduction...
