Transport measurements through crossed metallic single-wall nanotubes are presented. We observe a zero-bias anomaly in one tube which is suppressed by a current flowing through the other nanotube. These results are compared with a Luttinger-liquid model which takes into account electrostatic tube-tube coupling together with crossing-induced backscattering processes. Explicit solution of a simpl...

A generalized Wess-Zumino-Witten anomalous Lagrangian of psedoscalar, vector, and axial-vector fields has been used to study the γ → 3π anomaly. A correction of the low energy theorem of the γ → 3π is found. Both the amplitude A3π(0, 0, 0) and the cross section, σ z , of π+(Z,A) → ππ+(z,A) are calculated. Theoretical values agree well with the data. In this study there is no new adjustable para...

In this paper, a new two-parameter window function - Raised semi-ellipse (RSE) is proposed. The obtained from fixed elliptical known as Semi-ellipse by raising the radius of minor axis parameter (β), and applied for design finite impulse response (FIR) digital filters. spectral parameters proposed are determined first compared with Kaiser – 2-parameter adjustable window. Subsequently, in its ap...

Modern wind turbines are designed in order to work in variable speed operations. To perform this task, wind turbines are provided with adjustable speed generators, like the double feed induction generator. One of the main advantage of adjustable speed generators is improving the system efficiency compared to fixed speed generators, because turbine speed can be adjusted as a function of wind spe...

While the lattice Boltzmann method (LBM) has become a powerful numerical approach for solving complex flows, the standard LBM typically uses a square lattice grid in two spatial dimensions and cubic lattice grid in three dimensions. For inhomogeous and anisotropic flows, it is desirable to have a LBM model that utilizes a rectangular grid. There were two previous attempts to extend the multiple...

This paper investigates the construction of a wide class of singlehidden layer neural networks (SLNNs) with or without tunable parameters in the hidden nodes. It is a challenging problem if both the parameter training and determination of network size are considered simultaneously. Two alternative network construction methods are considered in this paper. Firstly, the discrete construction of S...

In rapid alloy solidification the dendrite-growth velocity depends sensitively on the deviations from local interfacial equilibrium manifested by kinetic effects such as solute trapping. The dendrite tip velocityundercooling function was measured in dilute Ni~Zr! over the range 1–25 m/s and 50–255 K using electromagnetic levitation techniques and compared to theoretical predictions of the model...
