To some extent, the academic scores of students reflect the teaching level of a school. Taking the students taught by me in 2010 as study objects, from the teaching perspective the paper studies the factors affecting the exam scores in advanced mathematics by using the method of multiple liner regression. The study result shows: although there are some differences in mathematics foundation among students, yet they can still make a great progress in mathematics study and they will have no difference in exam scores, as long as they are willing to spend time, willing to study hard. Meanwhile, the class atmosphere and the learning atmosphere can also play an important role in improving student exam scores. © 2011 IEEE. Source

Based on hypocycloid characteristic and transmission principle, a new kind of hypocycloid energy transformation mechanism was proposed. This new mechanism could realize the transformation between rectilinear movement of piston and rotating movement of crank and eliminate the piston sideforce. And the prototype and FEM model for the new mechanism was built by Solidworks and ANSYS software. Then the analysis and optimization for their intension and stiffness were carried out. The stress distribution and strain distribution of the key parts were obtained under the maximum exerted force. Further more, the safety factor was obtained and the strength evaluation was performed. The result shows, the intension and stiffness of the new mechanism is adequate. And the simulation results established the important theoretical foundation for further study of the new type hypocycloid energy transformation mechanism. © 2010 IEEE. Source

Dynamic frequency sweep tests are performed using dynamic shear rheometer AR-2000 for different dosage of modified asphalt TLA in viscoelastic range line, the use of DMA time-temperature equivalence principle, to obtain a different TLA modified asphalt in various dosage temperature dynamic shear modulus master curves, the results show that: the time-temperature equivalence principle based on material obtained within the wide temperature range of broadband frequency range of the main curves big leap for the accurate description of the different dosage of modified asphalt TLA dynamic shear modulus trends provided the conditions; TLA modified asphalt dynamic shear modulus at the same temperature trends with frequency and dosage of the TLA, in double logarithmic coordinates, with the increased dosage of TLA , the dynamic shear modulus versus frequency rate decreases, the frequency dependence is getting better.

Die burn probability of GOA TFT LCD product is very high in shorting bar testing. Testing waveforms with higher source voltage than the theory were designed. Testing samples were tested in two testing waveforms respectively. Experimental results showed that die burns probability is same in two testing waveforms. A current limiter is added on each testing signal output of testing driving plate. Testing samples were tested on two testing fixtures respectively, one loaded current limiter, the other not. Experimental results show that die burns probability is also same. Anti-static measures had been used to a shorting bar testing fixture. Testing samples were tested on two shorting bar testing fixtures, one with anti-static electrostatic measure, the other not. Experimental results show that die burns probability is zero using the anti-static electrostatic fixtures. Result of three experimental showed that the root cause of die burn is Electro-Static discharge. © 2015, Science Press. All rights reserved. Source

With analysis of DV-Hop localization algorithm, in order to improve the accuracy of localization algorithm, this paper provides a new localization algorithm, SN-Hop (Hop Localization Algorithm Based on Area Singular Nodes of Network), which introduces Network Area singular Nodes into the localization algorithm. By referring to the Ant Colony Optimization Algorithm, SN-Hop added the Path Molarity to the unknown nodes to mark the area singular nodes of network. When localization path passes a node each time, the Path Molarity of this node is increased with 1 unit. Then the nodes with most Path Molarity except for anchor nodes and anchor nodes' peer node are selected as effective singular nodes. At last, the paths including singular nodes are amended by replacing the anchor nodes with the singular nodes. With simulating experiments, the results show that the localization accuracy and algorithm performance are improved obviously by introducing the singular nodes to localization algorithm. Especially in the irregular networks the SN-Hop shows more remarkable achievement of localization accuracy improvement. Furthermore, SN-Hop is with better applicability and practicality than DV-Hop.
