Issue date:May 2011 Publication year:2011 Pages:539-556 Language:English ISSN:10954244 E-ISSN:10991824 Document type:Journal article (JA) Publisher:John Wiley and Sons Ltd, Southern Gate, Chichester, West Sussex, PO19 8SQ, United Kingdom Abstract:A newly developed technique for determining the angle of attack (AOA) on a rotating blade is used to extract AOAs and airfoil data from measurements obtained during the MEXICO (Model rotor EXperiments in COntrolled conditions) rotor experiment. Detailed surface pressure and Particle Image Velocimetry (PIV) flow fields at different rotor azimuth positions are examined for determining sectional airfoil data. The AOA is derived locally by determining the local circulation on the blade from pressure data and subtracting the induction of the bound circulation from the local velocity. The derived airfoil data are compared to 2D data from wind tunnel experiments and XFOIL computations. The comparison suggests that the rotor is subject to severe 3D effects originating from the geometry of the rotor, and explains why the Blade Element Momentum technique with 2D airfoil data over-predicts the loading of the rotor. The extraction technique is verified by employing the derived airfoil characteristics as input to computations using the BEM technique and comparing the calculated axial and tangential forces to the measured data. The comparison also demonstrates that the used technique of determining the AOA is a reliable tool to extract airfoil data from experimental data. © 2010 John Wiley & Sons, Ltd.

Conflict point and conflict probability were selected as the two key factors, one of which was analyzed using the diagram method and photogrammetry principle, and the other determined by using statistical analysis and curve fitting. The complexity degree values of intersections of different spatial layout under various traffic demands were calculated. The results indicate that the complexity degree values of intersections of the same type increase with volume and those of intersections of different types increase with the number of lanes. Complexity degree is a comprehensive quantitative index showing the working condition of intersections, and can be applied to planning urban road networks and safety appraisal of intersections.

The transfer of compounds between the phases was followed by visual observation of new phases appearing and the movement of the interfaces with time. The results revealed that, conversely to the equilibrium processes in the corresponding salicylate emulsions, in the present system the dissolution of the acid was faster than the formation of birefringent structures and the variation of different colloidal structures could be followed in the experiment. A suitable choice of initial ratio between the three compounds enabled the transfer of compounds to result in an early depletion of the solid acid and subsequently information could be obtained about the relation between the transport of surfactant and water-acid solution into the birefringent layer. A significant dependence was found between the composition of the entrants into the layer and the amount of surfactant liquid remaining. © Taylor & Francis Group, LLC.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Avalanche or cascade failure is ubiquitous. We first classify the cascading phenomena into two categories: the cascading disasters which result in large-scale functional failures and the cascading events that do not lead to disasters. We elucidate that two important factors, the increasing amount of events and the acceleration of event frequency, can induce the crossover from the cascading phenomenon to the cascading disaster. Through a simplified sandpile model and a heuristic logistic map, we demonstrate that the dependence of the event number on the observation time behaves as a power-law and as an exponential for these two different cascading events, respectively. The analytic derivations are found to be consistent with several empirical observations. Our present findings contribute to the understanding of the transition between different cascading events, providing a basis for the further understanding of the transitions among more general critical events. © 2011 Elsevier B.V.

Firstly, chemical structures of PoPD sub-microspheres were performed by Fourier-transform infrared (FT-IR), UV-vis, 1H NMR spectra, X-ray diffraction (XRD) and GPC analysis. When used as adsorbents, both PoPD hollow and solid sub-microspheres showed high adsorptivity and adsorption capacity towards Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions in water, and mechanisms of adsorption behaviors were revealed by XRD and X-ray photoelectron spectra (XPS). It was found that the pH and concentration of Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ion solution, as well as contact time and adsorbent dosage affect the degree of adsorption. Adsorption isotherms and kinetics of Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions onto PoPD sub-microspheres were also investigated according to experimental data. Comparative investigations of adsorption behaviors revealed that hollow sub-microspheres showed enhanced adsorptivity adsorption capacity towards Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions as compared with solid sub-microspheres typical at low adsorbent dosage. PoPD hollow sub-microspheres also showed good adsorptivity for other heavy-metal ions, such as Hg(I{cyrillic, ukrainian}I{cyrillic, ukrainian}), Cd(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) and Cu(I{cyrillic, ukrainian}I{cyrillic, ukrainian}), which implied their potential applications as effective adsorbents for heavy-metal ions in water. © 2011 Elsevier Inc.

In order to overcome such shortcoming, a fast and efficient algorithm named FBPM for mining frequent patterns in biological sequence is proposed. We first present the concept of primary pattern, and then use prefix tree for mining frequent primary patterns. A pattern growth approach is also presented to mine all the frequent patterns without producing large amount of irrelevant patterns. Our experimental results show that FBPM not only improves the performance but also achieves effective mining results. © 2011 IEEE. Number of references:23 Yüklə 2,34 Mb. Dostları ilə paylaş:
