Pore structure characterization of porous building material by X-ray computed tomography (XCT) and X-ray microscopy (XRM) by Chengnan Shi, Jeroen Soete, Hans Janssen

“…Additionally, scanning the same sample with a finer voxel size naturally captures more details, and allows the pore network extraction algorithm to better preserve pore structure. On the other hand, the impact of sample size on pore network characterization for ceramic brick is negligible if the oversized sample allows sufficient X-ray transmission.  …”

A Two-Stage Method for Structural Damage Prognosis in Shear Frames Based on Story Displacement Index and Modal Residual Force by Asghar Rasouli, Seyed Sina Kourehli, Gholamreza Ghodrati Amiri, Ali Kheyroddin

“…In the second stage, by defining a new objective function, the extent of the actual damage is determined via an imperialist competitive algorithm. The performance of the proposed method is demonstrated by implementing the technique to three examples containing five-, ten-, and twenty-five-story shear frames with noises and without them in modal data. …”

Delay-constrained and jitter-optimized traffic allocation for multipath routing in wireless mesh networks by CHEN Zhi-gang1, ZENG Feng1, LI Qing-hua1

“…In order to improve the QoS for multimedia application,which focused on the delay-constrained and jit-ter-optimized traffic allocation problem in multipath routing.First of all,based on the network calculus theory,a deep analysis on the upper bound of delay in the single route transmission was dore,and deduce the upper bound formulation of delay and jitter in multiple route transmission,and find out the maximum income rate satisfying the delay constraint for a route.Then,based on the upper bound of delay and jitter,a delay-constrained and jitter-optimized traffic allocation algorithm DCJOTA was proposed,which distributes the traffic to a route in proportion to its maximum income rate,and does some adjustment to optimize the jitter.At last,the implement methods of DCJOTA were given to run in NS2,and simulation is done.Experimental results show that the DCJOTA embedded multipath routing protocol DCJO-AOMDV outperforms AOMDV at the term of end-to-end delay and jitter.Compared with AOMDV,DCJO-AOMDV has made the end-to-end delay and jitter decreased by 3.9% and 24.5% respectively.But,DCJOTA puts a litter complexity on the rout-ing protocol,which leads to the network throughput decreased by 1.7% in DCJO-AOMDV.…”

Spatial spectrum based blind spectrum sensing for multi-antenna cognitive radio system by Chang LIU, SajjadAli Syed, Rui ZHANG, Si-ying LI, Jie WANG, Ming-lu JIN

“…State-of-the-art sensing methods only exploit three dimensions of the spectrum space:frequency，time and space whereas the angle dimension has not been exploited well enough for opportunistic spectrum access.Motivated by this，the authors apply angle of arrival (AOA) estimation algorithm to spectrum sensing and propose two blind spectrum sensing methods based on spatial spectrum.First is based on the ratio of maximum to minimum delay-sum spatial spectrum; the other is based on the ratio of average to minimum delay-sum spatial spectrum.Taking the advantage of spatial matched filtering，the proposed methods can achieve high probability of detection as well as offer the AOA information for spectrum access，which improve the spectrum efficiency.In addition，utilizing latest random matrix theories (RMT)，this work quantifies the detection threshold and derives the probabilities of detection for the proposed methods in theory.Extensive simulations carried out in Nakagami-m fading channel indicate that the proposed methods outperform the existing blind spectrum sensing methods.…”
