Our data indicate that the three-ring bent-core LC 1,3-phenylene-bis(4-butoxybenzylideneamine) exhibits mesogenic properties between 55-60°C.
The reduction of the nucleating sites should result in a larger single crystal.

Self-Pierce Riveting is a key technique applied to automotive aluminum alloy body in weight reduction and energy conservation.
With the powerful data processing and numerical calculation function of Matlab, programs of kinematics functions can be written and solved to get the position, velocity and acceleration in the end center of the riveting manipulator, as shown in Fig. 3: Fig. 3: (a) X, Y, Z position curves (b) X, Y, Z velocity curves (c) X, Y, Z acceleration curves Analysis of kinematics simulation based on ADAMS The virtual prototype model of the riveting manipulator can be built by ADAMS, as shown in Fig.4: Fig.4 Virtual prototype model of riveting manipulator The virtual movement analysis can be made through the manipulator’s virtual prototype model built by ADAMS [8] .The position, velocity and acceleration in the end center of the riveting manipulator can be dynamically observed through the measure window in the simulation process.

Reductions of deformation characteristics of material lead up to a drop in stress, that allow to decrease reinforced shell thickness, more usefullyspread reinforcement in section, increase peak load.
Experimental data () of the Young's modulus depending on the temperature of concrete and the graph of the approximating function.

Reliability of Pile foundation of Offshore Jacket Platforms Subjected to Seismic Action ZHAO-WEI SHEN1, XIAO-HONG WANG2, WEI-LIANG JIN3 1Zhejiang Key Laboratory of Water Conservancy Disaster Prevention and Reduction, Zhejiang Institute of Hydraulics & Estuary, Hangzhou, 310020, China 2Zhejiang Guangchuan Engineering Consulting Co., Ltd, Hangzhou, 310020, China 3Institute of Structural Engineering, Zhejiang University, Hangzhou 310058, China Keywords: Pile foundation, offshore jacket platform, Reliability, Seismic Action Abstract.
Researchers have proposed on the basis of the theory of random field model, static sounding (CPT) according to the data calculated soil related distance, and then calculate the pile resistance statistical characteristic, finally calculate reliability index.

While indirect property indexes indicated eight indexes (heat loss reduction, heat transfer coefficient, clo, air-permeability, moisture regain, water-vapour permeance, equivalent water-vapour permeance and water-vapour permeance resistance) which came from four facets (warm, moisture-penetrability, air-permeability and moisture absorption).
To reduce the impact induced by standard deviation on principal component analysis, all the data were normalized by the following equation: (1) Where x' = correction value, x = original value, xmax = original maximum value, xmin = original minimum value.

Time-HistoryVertical Acceleration data of rail sampled are plot bellow.
Attenuation effect of damping fastener is great contrast to fastener with no damping, acceleration amplitude reduction archives 50%.

By comparing computational results with experiment data (Fig. 2b), the result shows that STRUCT2D can be used by airfoil optimization.
The optimization result shows a great drag reduction by numerical optimization.

Introduction In advanced ultra large scale integration (ULSI) technology, reduction of line size and spicing width increases the metallic line resistance as well as parasitic capacitance, resulting in signal propagation delay and cross talk [1].
FTIR analysis data shows that Si-F and SiـO bonds can be created during the deposition process because F and O radicals easily react with Si.

Mode predictions shown in both figures are quite consistent with experimental data in terms of dominant dynamic characteristic and the direction of steady state change.
The next step is model reduction and control method design.

This system centered on the network intelligent control data terminal products of a plan, because the product focused security, disaster prevention, for help, three table control functions such as copy, information release and home appliance, so the system has high integration, design is simplified, the cost is greatly reduced, with high cost performance.
