Box 211, Amsterdam, 1000 AE, Netherlands Abstract:We investigated the properties of the spin-1/2 ferromagneticantiferromagneticantiferromagnetic alternating Heisenberg chain using the spin-wave theory. The spin-wave excitation spectra, the sublattice magnetizations and the local bond energies of the model are calculated to be compared with the corresponding properties of the mixed spin (1, 1/2) chain for a range of α. The results demonstrate that all the properties show similar behaviours in the small α limit, so the properties of the mixed spin (1, 1/2) chain can be described using the spin-1/2 ferromagneticantiferromagneticantiferromagnetic alternating Heisenberg chain. © 2010 Elsevier B.V.

The obtained CS/PCL vascular scaffolds were characterized by SEM and electronic universal testing machine. The endothelial progenitor cells(EPCs) were implanted in the scaffolds with various mass ratios of CS to PCL. The vascular scaffolds were examined by adhesion rate in different culturing times and the cells breeding was observed. The obtained CS/PCL vascular scaffolds show porous, nano-structured surfaces, similar to the natural extracellular matrix. When the mass ratio of CS to PCL is 0.5, the breaking elongation of CS/PCL vascular scaffolds reaches 31.64%, and the curves of stress-strain indicate that the obtained vascular scaffolds possess good elastic deformation. The adhesion rate of EPCs on CS/PCL vascular scaffolds is 95.1%, the observation of EPCs labeled with CM-DiI(chlormethylbenzamido-1, 1 dioctadecy l-3, 3, 3′, 3′-tetramethylindocarbocyamine)after culturing 72 h by fluorescence microscopy also illustrates that CS/PCL vascular scaffolds are beneficial to cell growth and cell adhesion.

Cyclic voltammograms demonstrate that the oxidation peak of aniline on the first cycle shifts from 1.13 V on the bare GC electrode to 0.76 V on the graphene/GC electrode. In addition, both amperometric and potentiometric methods also demonstrate that graphene can effectively catalyze the electrochemical oxidative polymerization of aniline. Cyclic voltammetry confirmed that graphene can pronouncedly catalyze the electrochemical oxidative polymerizations of o-aminophenol and m-aminophenol, but graphene oxide hardly catalyzes the electrochemical oxidative polymerizations of aniline and its derivatives. The ESR spectrum of graphene is quite different from that of graphene oxide. © 2010 Elsevier Ltd.

The results showed the rate determining factors to be the extremely slow absorption of compounds into the solid acid layer and of water into the surfactant inverse micellar solution. The former factor was referred to the protracted process of modifying the crystalline structure and the latter to the minute diffusion coefficient of the inverse micelles. In the same manner the contact between the lamellar phase liquid crystalline phase and a solid solution of the surfactant in the acid led to the formation of two inverse micellar solutions of different composition separated by a liquid crystalline layer instead of the expected aqueous liquid and one inverse micellar solution, which appeared first after significantly extended times. The equilibration was significantly retarded by the slow diffusion of acid molecules through one of the liquid layers. © Taylor & Francis Group, LLC.

Issue date:February 2011 Publication year:2011 Pages:263-270 Language:Chinese ISSN:10010920 CODEN:KYJUEF Document type:Journal article (JA) Publisher:Northeast University, P.O. Box 125, Shenyang, 110005, China Abstract:Based on backstepping, an adaptive neural network control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown time-varying delays and virtual control coefficients. By choosing appropriate Lyapunov-Krasovskii functionals, the unknown time-varying delay uncertainties can be compensated for. The continuous approximation functions are constructed to solve the singularity problem which occurs when neural networks are used to approximate the unknown nonlinear functions. By introducing a new intermediate variable, the derivative of virtual control is guaranteed to be right. Simulation results show that the proposed controller can guarantee that all the signals in the closed-loop system are semi-global uniformly ultimately bounded, and the tracking error converges to a neighborhood of zero.

Because the short circuit current of solar cell is alternated with cell's rotation, a method with minor components and large range measurement is put forward, and the angles are obtained by calculating the phase of short circuit current with DFT. The difference between components is avoided because an angle is gotten by once cell rotation. Short circuit current characteristic with rotation angle and test results are presented. The test results show its effectiveness.

Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:In order to overcome the shortcomings of traditional algorithms, the algorithm MSPM was proposed. It used longer patterns for mining, which avoided producing lots of patterns with short length. Meanwhile by the use of prefix tree of primary frequent patterns, we extended the primary patterns which avoided plenty of irrelevant patterns. The experimental results show that MSPM not only improves the performance but also achieves effective mining results. © (2011) Trans Tech Publications.

Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:Higher pair contacting components is worn more severely than lower pair contacting components due to the larger contact stress on the contact line. To improve antifriction of higher pair contacting components, the paper proposes a new method by which a large number of micro-deep holes are fabricated on the surface of the contacting component. When higher pair operates, contact stress near the contact line will cause obvious elastic deformation and the volume of the micro-deep holes near the contact line will change, resulting in absorbing oil and squeezing oil. Then an oil film with certain pressure is generated around the micro-deep holes, which will improve the lubrication of components greatly. In addition, a test is carried out and its result shows that the cylindrical roller with micro-deep holes performed better in terms of antifriction than the smooth cylindrical roller. © (2011) Trans Tech Publications.
