With the advancement of urban rail transit towards intelligence, demand for communication has increased significantly, but traditional vehicle–ground system been unable to meet future requirements. To improve performance communication, paper proposes a reliable low-latency multipath routing (RLLMR) algorithm ad hoc networks. First, RLLMR combines characteristics networks and uses node location information configure proactive reduce route discovery delay. Second, number transmission paths is...
Abstract Taking the longitudinal deformation into consideration, a two-dimensional beam theory is proposed, and new layered model established subsequently for composite laminates with multiple through-the-width delaminations. The undelaminated portion regarded as separate beams along layer interfaces, interface continuities are satisfied using generalized variational principle. Comparisons of present analytical solutions three-dimensional finite element results classical made to verify...
Based on the microstructure, a novel theoretical method was proposed to predict equivalent stiffness and failure strength for stitched foam-core sandwich composites. Experimental studies were also carried out. Considering different thickness increment of laminated face-panels stitching density influence angle width resin pocket zone, modified fiber distortion model developed evaluate by combined series-parallel model. As prediction strength, composite analyzed classical laminate theory local...
A mathematical model based on minimal thermal resistance and equal law of specific equivalent conductivity is developed to discuss the heat transfer characteristics ablative insulating material from mesoscopic scale. Based statistical results parameters, microstructure unit cell was established analyze influence rule parameterization which includes size, distribution, positional relation microsphere fiber. The show that decreases with density, distribution area, distance space volume...
The package size for Application-Specific Integrated Circuit (ASIC) becomes larger; the mainstream is above 50mm * current communication and networking ASICs with more than 2000 IOs. It will take time to assign logical connections from chip solder bump ball across substrate before layout design start, so an effective method of automatic assignment key turn-around (TAT) reduction. benefit TAT reduction drive fast market based upon chip-package co-design methodology. An example real ASIC in...
A two dimensional beam model is proposed for delamination analysis of composite laminates, where Timoshenko's plane cross-section assumption abandoned, and the longitudinal displacement as continuous functions transverse coordinates, to match shear deformations. Moreover, laminate modeled upper lower sub-beam through interface, corresponding conditions interface sliding are satisfied a generalized variational theory. The accuracy results this analytical verified by comparison with those from...
