Based on the comparison of several types of core formwork for large span hollow box girder, their structural characters, and assemble and disassemble in application is analysed to find that steel-wood core formwork is a better choice. Then the installation technique of steel-wood core formwork is discussed, including assemble, disassemble and anti-floating counter measures. The practice in some large span prestressed hollow box girder construction prove that steel-wood core formwork is a simple but effective core formwork construction technique with technological economic advantages because of its low cost, high working efficiency and better accuracy. © (2014) Trans Tech Publications, Switzerland.

The transferring of electronic signal from rotating work piece or cutter presents a challenge problem. In this paper, a wireless communication method is proposed to transmit signal from rotating bodies. The corresponding device including the signal input & transmission module and the signal receiving and processing module was fabricated. The working principle of the wireless system is introduced, and a series of experiment is set up to calibrate the system accuracy and to measure the cutting temperature of the rotating work piece. The experimental results show that the wireless system has a satisfactory reliability and temperature measurement accuracy.

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.

Foundation treatment is necessary when the construction is built on soft ground; Reinforcing is superior to many other methods when embankment is built on soft ground. This paper adopts slide block balance analysis of the composite foundation bearing capacity consisting of the horizontal reinforced and discrete material pile, while considering the level friction resistance from the reinforcement and ground on the foundation bearing capacity influence. and it is applied to practical engineering. The results show that the method is feasible. © (2013) Trans Tech Publications, Switzerland.

In this article, the relationship between the Borel direction of algebroidal function and its coefficient functions is studied for the first time. To begin with, several theorems of algebroidal functions in unit disk are proved. By these theorems, some interesting conclusions are obtained. © 2014 Wuhan Institute of Physics and Mathematics.

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.

With the growing economic level and the continuous development of information network technology, as well as the continuous improvement of people's living standards, transportation demand gradually increased. Due to the current transportation system in China has been facing the problem of traffic congestion and inefficient, and cause serious pollution and energy shortages, and intelligent traffic management system is the key to solve these problems, the modern information network technology and transportation combined. This article gives a brief introduction to the development and study of the status quo of China's intelligent transportation management system, intelligent traffic management system architecture of CORBA and CORBA, and described the implementation of an intelligent traffic management system based on CORBA. © (2013) Trans Tech Publications Switzerland.

Through the dynamic creep test of the TLA modified asphalt with different contents, based on the Burgers model viscoelastic theory fitting analysis, this paper focuses on the model parameter variation with temperature and content, and with different contents of the creep curve the shape variation. The results show that the higher of the TLA modified asphalt creep curve, any content TLA modified asphalt can be fifed by the Burgers model, as the temperature rises, all the parameter values were significantly smaller; the GV values rises by the temperature, the GV rate of increase was more significant when the dosage is greater than 30%; the TLA modified asphalt creep curve shape of the three stages was closely related to the parameter size.

The experimental platform simulating ship wave movement for the measurement and integral of acceleration data, driven by hydraulic pressure, is designed and set up. By the spectral analysis and experimental research on integral of acceleration data, the solving measures to remove the direct-current component, low-frequency component, high-frequency component and integral constant item are put forth. The integral method of acceleration data in time domain and in frequency domain is also put forth. The key technical problems in measurement system of ships wave movement based on accelerometer array, the soft integral of the measured acceleration data, is successfully solved.
