Located in Guangxi Province, China, the Liuzhou Iron and Steel Company is one of China’s leading suppliers of plate steel to its shipbuilding industry. Also exporting to countries such as Japan, Germany, Singapore and Thailand, the company is now capable of producing one million tons of steel per year, owing to a series of recent technical innovation projects. Foremost among these is an ongoing...

This paper describes the mitigation of shaped charge penetration of steel armour by the use of spaced metallic and composite plates. The target consisted of one or more steel plates of 10mm thickness some of which were backed by 25mm E-glass polyester composite panels at various additional spacings from the rearmost steel plate. A 32mm diameter shaped charge warhead was detonated at a standoff ...

How to update spatial information in real time or near real time has become a bottleneck in the construction of the Antarctica Spatial Data Infrastructure (AntSDI). An automatic sensor processing workflow (SPW) approach consisting of sensor discovery and retrieval service; snow, water, ice, land and cloud (SWILC) Web processing service (WPS); and an SPW engine under the Sensor Web environment i...

A new conceptual non-thermal anti-icing system for helicopter rotor blades is introduced. Theoretical calculations predict that certain ultrasonic modes generated by horizontal shear waves produce sufficient interface stresses between a host structure and ice to remove the accreted ice layer. Experimentally obtained ultrasonic shear dispersion curves are compared to theoretical predictions for ...

In this study, we developed an algorithm for detecting seam cracks in a steel plate. Seam cracks are generated in the edge region of a steel plate. We used the Gabor filter and an adaptive double threshold method to detect them. To reduce the number of pseudo defects, features based on the shape of seam cracks were used. To evaluate the performance of the proposed algorithm, we tested 989 image...

Oscillations in hippocampal local-field potentials (LFPs) reflect the crucial involvement of the hippocampus in memory trace formation: theta (4-8 Hz) oscillations and ripples (~200 Hz) occurring during sharp waves are thought to mediate encoding and consolidation, respectively. During sharp wave-ripple complexes (SPW-Rs), hippocampal cell firing closely follows the pattern that took place duri...

The corrugated steel plate shear wall (CoSPSW) is a new type of wall, in which plates instead flat are adopted. lateral stiffness and buckling capacity the system could be significantly enhanced, then, under gravity loads would mitigated. This paper presents study on probabilistic assessment seismic performance vulnerability CoSPSWs using fragility functions. damage states corresponding repair ...

Based on shear strength reduction finite element method, stability of retaining wall with relieving plate has been analyzed. Due to the structure character of retaining wall with relieving plate, it can be found that fracture surface could hardly cross the triangle area of between lower wall and soleplate, between upper wall and relieving plate, so the second fractured surface occurred at there...

existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

Transfer of neuronal patterns from the CA3 to CA1 region was studied by simultaneous recording of neuronal ensembles in the behaving rat. A nonlinear interaction among pyramidal neurons was observed during sharp wave (SPW)-related population bursts, with stronger synchrony associated with more widespread spatial coherence. SPW bursts emerged in the CA3a-b subregions and spread to CA3c before in...
