Published: March 2013

Auditory phase-synchronization near 40Hz is reportedly related to sensory stimulation. This study applied the phase synchrony analysis and Bi-coherence analyses to analyze the electroencephalographic measurements. Four experimental stages were conducted with 34 healthy high school students to collect the data: (A) resting with eyes closed, (B) listening to the classical music, (C) resting with eyes closed, and (D) listening to popular music. The result shows that the whole brain phase-synchronization occurs at 40Hz and lasts about 400 ms, which is quite different from the estimated 40Hz phase-coupling lasting about 20–25 ms in previous studies and seems to play an important role in inducing auditory attention loss. Additionally, the result also shows that hypersynchronous states may affect perceptual processing. This study develops an original nonlinear time serial analytical approach and suggests that 40Hz phase-synchronization might be an important indicator in perceptual process.

Authors: Liu Chien Hung , Chang Po Yin , Huang Chun Yuan
Published: March 2013

For eLearning, how to naturally measure the learning attention of students with lower cost devices in an unsupervised learning environment is a crucial issue. Students often far away and out of teachers’ control in above situation which may cause students do not have strong learning motivation and might feel fatigued and inattentive for learning. A real-time and naturally learning attention measure approach can support instructor to better control the learning attention of students in unsupervised learning environment. This paper proposes an integrated approach, named Real-time Learning Attention Feedback System (RLAFS) which could naturally measure learning attention in unsupervised learning environments. The system architecture of RLAFS consists with three layers: first layer is Image preprocessing layer, which is responsible for image processing and motion detection. Second is eyebrow region detection layer, which is focus on the features of face and eyes capturing and positioning. Classifier layer is the third layer, in which integral image, volumetric features and finite-state-machine are used to capture the current state of learning attention of students. Consequently, support vector machine is utilized to classify the level of learning attention. The experiments are conducted in an unsupervised environment, and results showed RLAFS is a promising approach which can naturally measure learning attention and has a significant impact on learning efficient.

Authors: Wu Ying Long , Zhao Hua , Zhang Guo Gang , Wang Meng
Published: March 2013

For optimizing hydraulic absorbers energy absorbing, weve studied the effects of the velocity point (Vmax), the valves opening gate (V0), the stage after the valve is open and the hysteretic lag. The equations of the F-V history curve and the F-S curve at the stage before the valve is open (T1) and after the valve is open (T2) were set up. When Vmax was bigger, T1 was shorter and the displacement of the opening gate (S0) was smaller. But S0 was approximate to A. If we advanced V0, S0 would be smaller, but S0 was was still close to A and it might cause an abnormal vibration. The F-S curve was an ellipse curve at T2. The area of this ellipse was close to k2, but the plumpness degree (φ) was a constant. The damping forces hysteretic lag would induce the F-S curves un-plumpness and over-plumpness. The un-plumpness is more severe than the over-plumpness. It is proper to use the opening gate instead of Φ to describe the damping forces hysteretic lag.

Authors: Zhang Qing Fang
Published: March 2013

This study used ordinary portland cement of 42.5 strength grade, mixed with various minerals and water reducer for the preparation of concrete C30 by means of four schemes, for each of which a specific mix proportion was employed. Accordingly the compressive strength of concrete with different preparations at different ages were compared. No matter which scheme was employed, single or double doping, with or without superplasticizer, the compressive strength of concrete at different ages was maximized when slag amount was 30% or maximum. Hence it can be concluded that the reasonable content of slag should be 30% for the preparation of concrete C30. It is suggested that the above results can be better applied to large-volume concrete, underground, harbor, road and bridge and civil engineering as well.

Published: March 2013

With orthogonal tests the effects of grain refiners and modifiers, Al-10Sr, rare earth (RE) and Al-Ti-5B, on the mechanical properties of Al-Si alloy for automobile cylinder blocks were studied. The best result occurred when the proportion of refiners and modifiers was Al-10Sr = 0.1wt%, RE = 0.3wt%, Al-5Ti-B = 0.8wt%. With SEM and EDS the as-cast microstructures of materials after grain refining and modification were observed and analyzed. Tiny branch-shaped AlSi phase, thin-striped AlCu phase, new small bone-shaped AlSiMn phase, new leaf-shaped or feathered B(AlCuCe) phase as well as the phases of other metal compounds made the as-cast microstructures more complicated and more compact after grain refining and modification. Some brittle phases reduced in size obviously and distributed in the grain boundaries of plastic α-phase in network, which acted as intercrystalline strengthening to certain degree. During the tensile deformation these brittle phases could reduce the stress concentration, impeded dislocation movement, and then strengthened the alloy matrix.

In order to improve discharge characteristics of engine ignition, a dual-coil ignition was designed. Simulation models of ignition energy, secondary voltage and spark duration of this ignition were established. The influence of discharge time interval and energy distribution method on discharge characteristics of the dual-coil ignition was studied. Compared with single-coil ignition, the results show that dual-coil ignition produced higher secondary voltage, ignition energy and extended spark duration. When total ignition energy remains constant, the dual-coil coupled discharge mode can improve energy conversion efficiency. The ignition can achieve flexible switching of discharge modes and optimal control of discharge characteristics，which is beneficial for improving fuel economy and reducing exhaust emissions.
