We employed a method based on pseudorandom sequence modulation to suppress the system noise and sunlight interference for in situ measurement of algae concentration. Based on the theory analysis of the pseudorandom sequence modulation method, we established a measurement system. The excitation light was modulated by m sequence. The induced modulated fluorescence was demodulated by AD630 and then narrow-band filtered by a two-order Butterworth low-pass filter. The practical experiment results show that the linear response correlation coefficients of the measurement system reach up to 0.999 weather in a low concentration range (0~10μg/L) or in the whole concentration range (0.5~100μg/L).

Published: October 2014

A simple and rapid SPE-HPLC/PDA method has been developed for the quantitative determination of tetracyclines in soils. An ultrasonic extraction system for the soil samples was confirmed as a combination of a 1:2 ratio of EDTA-McIlvaine buffer solution with methanol by comparing the extraction efficiency of 4 solvents and optimising the combination ratio. The soil extracts were purified and concentrated by Oasis-MAX cartridge followed by HPLC separation and PDA detection. The optimal chromatographic condition effectively separated the object and interfering substance, which can improve the sensitivity of the instrument. The limits of detection were lower than 20 μg·kg-1, and the limits of quantification were no more than 60 μg·kg-1 for all compounds in the soil. The recoveries of tetracyclines peaked at levels of 50-500 μg·kg-1 and averaged at 62.1% to 108.9% with relative standard deviation values of less than 5%. This method was applied to analyse real soil samples from suburban Beijing farmland, and TC and OTC residues were detected in the soil.

The mechanical behaviors of dissimilar metal weld SA508-52M-316L in several environments were investigated by using tensile tests with smooth specimens, focusing on the behavior of SA508-52M weld part during slow strain rates testing (SSRT) at 290°C in nitrogen gas and in simulated primary water at different electrode potentials. The mechanical properties at room temperature of main materials were obtained first. When tested at 290°C, the weld exhibited characteristics of dynamic strain ageing (DSA), which was more significant when strain rate was decreased from 1x10-6 (1/s) to 3.1 x10-7 (1/s). When tested in the water at the potentials from-720 to +200mV(SHE) , SA508-52M specimens showed the mechanical behaviors almost the same as that in nitrogen gas, with ductile failure happened in the 52M bulk weld metal. When the potential was raised to +300 and +400mV(SHE), brittle failure of stress corrosion cracking (SCC) took place around the interface, causing the significant drop of elongation and reduction in area.

Authors: Imran M. , Chen Yue Fang , Zhen Ji
Published: October 2014

The main theme of this paper is to assure the importance of natural material like peat to remove oil from water. Elimination of oil from the water is not a simple task. It requires some particular processes to separate oil from water. Oil in water is not only harmful for sea life but also the few manufacturing processes like dyeing and finishing of textiles cannot be carried out efficiently because of low absorbency. That is why it is very much important to remove oil from water. It is known that peat has outstanding absorbency qualities, since in its natural state is has absorbed approximately 90% water, however, that on drying peat to approximately 5-10% moisture content in the manner , such peat can absorb other liquid materials, like oil. This paper will explore the ability of peat to take in oil from oil polluted water. The absorption of oil measured by designed experiment.

Authors: Yuan Ling Feng , Du Yu Liang , Wan Wei Bing
Published: October 2014

Saliency detection has been applied in many cases. This paper proposes a 2D hidden Markov model (2D-HMM) which exploits the hidden semantic information of image to detect the salient regions. A spatial pyramid Histogram of Oriented Gradient (SP-HOG) descriptor is used to extract feature. After encoding the image by a learned dictionary, the 2D-viterbi algorithm is applied to inferring the saliency map. This model can depict the shapes of targets, and also it is robust to the targets’ change of posture and viewpoint. To validate the model with human’s visual search mechanism, eye track experiment is employed to train our model directly from the eye data. The results show that our model achieves a better performance than eye data. Moreover, it indicates that learning from eye track data to figure out their targets is possible.

This paper presents a design of water level measurement sensor which relies on mechanical transmission tracking method. Since there is no need to place the sensor into the water, the life cycle is improved. Furthermore, by remote data transmission over the internet network, A real-time monitoring of the water level can be achieved, and thus significantly improve the overall management efficiency of reservoir resource utilization.

The effects of atmospheric particulates were more prominent in recent years, so accurate monitoring of particulate matter was a problem needed to resolve. In the existing particulate monitoring instrument based on the principle of Tapered Element Oscillating Microbalance method (TEOM),the particle concentration detection system was tapered quartz tube simple harmonic oscillator. Due to the oscillator relying mainly on analog circuit closed-loop self-excitation oscillator to drive, loop resonance frequency, oscillation stability and Q value was greatly influenced by the oscillator physical characteristics and the interference of mechanical structure and circuit design parameters. And oscillation frequency must be read by the digital circuit frequency detection system, then figured out the corresponding quality. In this paper, we studied a kind of composite oscillator tube which can overcome the lack of stability in the existing technology and reduce the impact of coexistence at the same time of digital circuit and analog circuit. And oscillator frequency step precision raised almost an order of magnitude compared with the national standard detection accuracy of 10ug.

Due to the influence of robot arm’s and patient’s cantilever’s weight a drive motor with large drive torque was required in the design of upper-limb rehabilitation robot. In order to solve this problem, a new gravity-supporting system that combines gas spring and tension spring to provide supporting force was presented.

Published: October 2014

This paper combines an analysis of structural modeling on security vulnerabilities and a focused behavioral model examination to develop a vulnerability model to depict and reason about security vulnerabilities. An in-depth analysis of the structural models and the corresponding diagram of the applications come from the investigation of not only multiple vulnerable operations on multiple objects being involved in exploiting vulnerability but also the vulnerability data and corresponding data flow inspections deriving from behavioral modeling of the application. We also propose a vulnerability model-based security testing approach that automatically generates security test sequences from vulnerability model diagram and transforms them into executable tests on the basis of the vulnerable operations and vulnerability data.
