Numerical Analysis of the GF/UHMWPEF Interply Hybrid NOL Ring Critical Volume Fraction
Authors: Xu Ming Lin , Wu Xiao Qing , An Ming Kang
Published: February 2012

The tensile test of NOL ring composites with different interply hybrid ratio is simulated by finite element software. The relationship between the stress of Naval Ordnance Laboratory(NOL) ring and the volume fraction of UHMWPEF is linear when the matrix suffering from the equal loading, but tower suddenly appears at the point of 56.25% which is about the critical volume fraction. The critical volume fraction of hybrid NOL ring is figured out on the basis of the constant strain model. By contrast, the results of the Finite Element Method (FEM) and constant strain model have subtle differences. Tooth contact analysis can exactly predict the stress of the interply hybrid NOL ring and the critical volume fraction of GF in interply hybrid NOL ring which has lower breaking strain than UHMWPEF does.

A New Algorithm for the System Identification of Shear Structures
Authors: Adhami Behnam , Niroumand Hamed , Khanlari Karen
Published: February 2012

In general terms, the aim of "System Identification" is to determine the dynamic characteristics of mechanical systems. These characteristics include both frequency characteristics (frequencies, mode shapes, and damping ratios) and the system's characteristic matrices (the matrices of mass, viscous damping, stiffness, Coulomb damping or coefficients of friction, and the Duffing stiffness). In such fields as "Damage Detection" in structures, identification of the system's characteristic matrices is of the same importance as the identification of the frequency characteristics, or even more so, by identifying these matrices, the intended goals in Damage Detection can be achieved. In line with such identification, a new algorithm for the system identification of shear structures is presented in the paper. Taking into account the fundamental and significant effect of noise attenuation in boosting the levels of precision and the correctness of system identification, this method helps to achieve noise attenuation by trimming noisy records in the frequency domain, in parallel with the identification of the structural system. The efficiency and precision of the method have been examined through the application of a "closed loop solution" to a five storey model of shear structure.

Authors: Zhang Wen Jie , Hu Mei Ling , He Hong Bo
Published: February 2012

A mixture of TiO2 and HZSM-5 zeolite was used for adsorption and photocatalytic degradation of an azo dye, Active Brilliant Red X-3B. ABR X-3B adsorption on HZSM-5 zeolite is quite small although the amount of HZSM-5 is as many as 0.5 g/l. Photocatalytic degradation of ABR X-3B on HZSM-5 is less than 5% after 90 min of irradiation. When the adding amount of HZSM-5 is 300 mg/l, the maximum decoloration rate on the mixture reaches 88.1% that is 22.7% more than that on pure TiO2. The variations of adsorption and photocatalytic degradation on the mixture are not large with changing of HZSM-5 amount from 0.05 g to 0.6 g.

Some Thoughts on Strong Unforgeability in Ring Signature Schemes
Authors: Wang Chen
Published: February 2012

A signature scheme is strongly unforgeable if the adversary cannot produce a new signature even on a queried message. Some methods have been proposed to enhance some regular signatures. However, if applied to ring signatures, such methods will break the anonymity, which is the soul of ring signatures. We introduce a modified method which can achieve both strong unforgeability and anonymity in the standard model. Applying this method to Shacham-Waters scheme, we get the first ring signature with strong unforgeability in the stand model.

Authors: Zhang Yang , Bai Wei
Published: February 2012

In existing researches on the spread of A-H share dual-listed companies, turnover rate is generally regarded as a proxy for liquidity, which ignores the speculative meaning of turnover. In fact, high turnover rate often reflects strong speculative characteristics of investors in A share market. In this paper the true meaning of turnover rate is considered that it’s unreasonable to use turnover rate as a proxy for liquidity. The turnover rate of dual-listed companies is not reflected as liquidity but speculation in A share market. And the meaning of turnover rate of dual-listed companies is not clear in H share market.

This article mainly describes a new technique of multiple-input multiple-output (MIMO) communication systems based on the recent communication demand. This technique, by pre-coding CSI (the channel state information) at the transmitter, is based on UCD (Uniform Channel Decomposition) algorithm for MIMO system. By Uniform Channel decomposition of channel matrix, the algorithm can decompose a MIMO downlink channel into multiple identical sub-channels. The power allocation applied to each sub channel in MIMO system is identical, and the MIMO channel’s capacity isn’t reduce when the SNR (Signal Noise Ratio) is low. The simulations show that the UCD scheme has a better performance than GMD (Geometric Mean Decomposition) scheme even without the use of error-correcting codes, and the Symbol Error Rate (SER) of UCD algorithm is lower than GMD’s at the same SNR. Consequently, MIMO system gets a better interference performance by UCD algorithm.

Published: February 2012

Utilized photomicrographs taken by scanning electron microscope (SEM), an accurate representative volume element (RVE) model for plain weave C/SiC composites is established. Based on the steady-analysis method, the in-plane and thickness direction thermal conductivity of the C/SiC composites are calculated as 25.6Wm-1K-1 and 12.1Wm-1K-1, respectively. The manufacturing flaws have different effect on thermal conductivity. Compared with RVE without flaws, the result shows that matrix cracks make thermal conductivity decrease by 7.2% in the in-plane direction and have little effect in the thickness direction; matrix porosities have a significant effect on thermal conductivity, which make the thermal conductivity decrease by 16.7% in the in-plane direction and decrease by 25.4% in the thickness direction. The variation law of thermal conductivity along with porosity volume is also observed: as matrix porosity volume fraction is increasing, the thermal conductivity of material shows significant decrease.

Published: February 2012

A novel ultra-wideband(UWB) bandpass filter with dual notch-bands and wide stop-band is proposed. The designed UWB BPF is cascading a coupled simplified composite right-left-handed (SCRLH) resonator and a ring slot resonator (RSR). The SCRLH resonator creates two different notch-bands. And the RSR unit suppresses the higher-order harmonics at the upper stop-band. The UWB BPF demonstrated good insertion/return losses and out-of-band rejections in simulation.

Published: February 2012

A tracking controller based on RBF (Radial Basis Function) neural networks compensating in vision based autonomous vehicles is designed in this paper. One input of the RBF compensating model are the lateral offset which measured by the vision system as the distance between the road centerline and the center of the vehicle a certain distance before. Another input is the steering angle which was collected when the vehicle was driving by a human testing driver. The controller is finally made by linearly fitting the parameter of the RBF neural networks. The stability is proven by composite Lyapunov functions. The robustness of the controlled system is theoretically investigated with respect to speed variations and uncertain vehicle physical parameters. Several simulations are made on a sedan vehicle to prove the effectiveness of this controller when perform path tracking on roads with an uncertain curvature.

Published: February 2012

Peer-to-peer (P2P) architectures have been proposed as an efficient and truly scalable solution for distributed virtual environments (DVEs). However, heavy and unbalanced network load has restricted the development of large scale DVEs. To solve this problem, this paper attempts to apply the mobile agent technology in DVEs. First, the virtual environment space was divided into a number of adjacent sub-spaces. Then, using the agent mobility, entities models moved themselves to the adjacent sub-space, and completed interactions with other entities in the sub-space. As a result, a significant part network load is transformed into local calculation load. The theoretical analysis results show that it is feasible and effective to ease the network communications bottleneck in the expansion of the DVEs.
