This paper presents an event-based monitor that ensures timely and accurate detection and recovery of system task faults. The monitor model is based on first order hybrid Petri nets, i.e., Petri nets that make use of first order fluid approximation. The proposed fault detection technique relies on a modular framework, so that elementary monitors can be connected with other monitors to check more complex systems while avoiding the state space explosion problem. Moreover, a fault detection and recovery monitor is specified for a system devoted to the automated preparation of pharmaceutical drugs. © 2015

Appropriate LES guidelines for the pedestrian wind environment in urban areas are being established by a working group from the Architectural Institute of Japan. In this study, large-eddy simulations were conducted for the flow field around an isolated building and within a cubic building array to clarify the influence of various computational conditions on turbulent statistics. First, a cross comparison study was performed by examining both experimental and large-eddy simulation (LES) results for various computational grid arrangements, sub-grid scale turbulence models, spatial derivation schemes (for the convection term), and convergence criterion for a coupling algorithm relating the flow and pressure fields in the flow field around an isolated building. Next, the appropriate computational conditions, obtained from the LES for flow around an isolated building, were applied to the LES for flow within a building array. © 9th Asia Pacific Conference on Wind engineering, APCWE 2017.

The production cross section of prompt Λc+ charm baryons was measured with the ALICE detector at the LHC at midrapidity in proton-proton (pp) and proton-lead (p–Pb) collisions at a center-of-mass energy per nucleon pair of sNN=5.02TeV. The Λc+ and Λ¯c− baryons were reconstructed in the hadronic decay channels Λc+→pK−π+ and Λc+→pKS0 and respective charge conjugates. The measured differential cross sections as a function of transverse momentum (pT) and the pT-integrated Λc+ production cross section in pp and in p–Pb collisions are presented. The Λc+ nuclear modification factor (RpPb), calculated from the cross sections in pp and in p–Pb collisions, is presented and compared with the RpPb of D mesons. The Λc+/D0 ratio is also presented and compared with the light-flavor baryon-to-meson ratios p/π and Λ/KS0, and measurements from other LHC experiments. The results are compared to predictions from model calculations and Monte Carlo event generators.

The influences of mooring lines and risers on the first order responses of a floating system moored with catenary cables have not yet been systematically studied;likewise, it’s not well understood when these influences may be seen primarily as a kind of added stiffness, added damping or added inertia, if not always a complex superposition of influences. The following paper presents several analyses and comparisons between methods in order to assess the actual influences of a bow turret in the pitch RAO of an FPSO system. Both frequency and time domain simulations were performed;and the results were compared with outputs from simplified algebraic formulations. Different sea depths and lines’ parameters/ configurations were considered in order to provide consistent comparisons and a coherent separation of influences into geometric stiffness, elastic stiffness, damping and inertia. The separation of influences gives important insights for further considerations of the turret influences on floating systems. © 2018 Taylor & Francis Group, London.

Poplar has become one of the major fast-growing trees in China. But it is difficult to use because of its small diameter and poor mechanical properties. Natural wood has fine porous structure and other characteristics. At the same time it has a low density, high elasticity, excellent mechanical properties and other characteristics. Especially for its anisotropy, the mechanical performance along the longitudinal direction is the best. Inspired by this phenomenon, based on bionics, this paper studied and analyzed the feasibility of using poplar LVL for manufacturing solid wood doors. Using modified phenolic resin, veneers were impregnated by vacuum and high pressure and dried at low temperature. Then the veneer mats was hot-pressed under a special high temperature pressure machine. By means of these methods, the compression ratio of poplar LVL went up to 15%-40%. And its mechanical properties including hardness, dimensional stability and bending strength were all better than common LVL, which showed a good bionic effect. Taking it as a new wooden door frame material, we improved the structure design of new type of wooden door. Instead of the usual impregnated paper veneer as the surface of the door, engineered veneer make the door surface looks like natural wood with fine figures. Based on bionic-character of poplar LVL and bioniccharacter of engineered wood veneer, we managed to use inferior material to replace high-grade hard solid wood in making wooden doors. It had a great significance for new technology for poplar.

The production of K*(892)0and ϕ(1020)resonances has been measured in p-Pb collisions at sNN = 8.16 TeV using the ALICE detector. Resonances are reconstructed via their hadronic decay channels in the rapidity interval −0.5 < y < 0 and the transverse momentum spectra are measured for various multiplicity classes up to pT = 20 GeV/c for K*(892)0and pT = 16 GeV/c for ϕ(1020). The pT-integrated yields and mean transverse momenta are reported and compared with previous results in pp, p-Pb and Pb-Pb collisions. The xT scaling for K*(892)0and ϕ(1020)resonance production is newly tested in p-Pb collisions and found to hold in the high-pT region at Large Hadron Collider energies. The nuclear modification factors (RpPb) as a function of pT for K*0 and ϕ at sNN = 8.16 TeV are presented along with the new RpPb measurements of K*0, ϕ, Ξ, and Ω at sNN = 5.02 TeV. At intermediate pT (2–8 GeV/c), RpPb of Ξ, Ω show a Cronin-like enhancement, while K*0 and ϕ show no or little nuclear modification. At high pT (>8 GeV/c), the RpPb values of all hadrons are consistent with unity within uncertainties. The RpPb of K*(892)0and ϕ(1020)at sNN = 8.16 and 5.02 TeV show no significant energy dependence.

The purpose of this paper is to develop models to predict the quality (bearing capacity of foundation and pile completeness) of the Cement Fly-ash Gravel (CFG) composite foundation. To ensure the models are useful to both designer and construction of composite foundation, the study employs a broad range of bearing capacity of foundation and pile completeness variables through investigating the load transfer mechanism and reinforcement mechanism of mattress layer mechanism, the pile, layer, replacement ratio, construction machinery and other aspects of CFG pile composite foundation systematic and comprehensively. In addition, the research develops a model integrating of support vector machine with particle swarm optimization (PSOSVM) for predicting the bearing capacity and pile completeness of the Cement Fly-ash Gravel foundation. This paper contributes to the scarce literature on design and construction of CFG pile composite foundation. The models developed in this paper are useful to give those design and construction of CFG pile composite foundation an early warning. And through specific examples of analysis, the model practical application effect was test. It was concluded that using the established model for CFG pile composite foundation quality verification, is of feasibility and validity. © 2016 CAFET-INNOVA TECHNICAL SOCIETY. All rights reserved.

Analytical Control of Homoclinic Bifurcation of the Hilltop Saddle in a Noncontact Atomic Force Microcantilever

引用

Procedia IUTAM 2016年 19卷 19-26页

作者： Valeria Settimi Giuseppe Rega Stefano Lenci Department of Structural and Geotechincal Engineering Sapienza University of Rome Via A. Gramsci 53 00197 Rome Italy Department of Civil and Building Engineering and Architecture Polytechnic University of Marche Via Brecce Bianche 60131 Ancona Italy

A control procedure of global dynamics is applied to a reduced order model of noncontact AFM with the aim to shift the homoclinic bifurcation involving the system hilltop saddle. The method consists of adding to the system harmonic excitation controlling superharmonics to be properly identified by solving an optimization problem. The analytical bifurcation threshold is determined through the asymptotic Melnikov method, for the reference system and for the controlled system. The practical effect of the control as regards possibly increasing the system overall robustness by shifting the start of the erosion of the safe basin is then numerically investigated by means of a dynamical integrity analysis based on the evolution of basins of attraction.
