In n-tuple Zipf analysis, ‘‘words’’ are defined as strings of n digits, and their normalized frequency of occurrence v is measured for a given ‘‘text’’ ~sequence of digits!. In the case of various non-Markovian sequences, the probability density of the frequencies P(v) has a power-law tail. Here we argue that a broad class of unbiased binary texts exhibiting a nonexponential distribution of clu...

The drainage network must take the farming systems and the landscape structure into consideration to describe flow pathways in the agricultural catchment. A new approach is proposed to build the drainage network which is based on the identification of the inlets and outlets for surface water flow on each farmers' field (or plot), estimating the relative areas contributing to the surface yield. ...

Integrated color indices corrected for galactic absorption, internal absorption, and redshift have been given for a large number of galaxies by de Vaucouleurs and de Vaucouleurs (1964). These indices may be compared with the maximum rotational velocities of galaxies that are listed in compilations by Brosche (1967, 1971). Such a comparison shows that there is a strong correlation between the in...

The temperature variations of the 6 3 Cu, 6 5 Cu and 5 V N M R spectra and 5 V spin-lattice relaxation rate 1 / T have been measured in a thiospinel CuV 2 S 4 . Drastic changes in the spectra and relaxation rates were observed at the charge density wave (CDW) transition temperature. With decreasing temperature T, 1 /Ti decreases exponentially due to the C D W transition (75 K < T< 90 K). The en...

Current-voltage measurements of metal-molecule-metal junctions formed from pi-conjugated thiols exhibit an inflection point on a plot of ln(I/V(2)) vs 1/V, consistent with a change in transport mechanism from direct tunneling to field emission. The transition voltage was found to scale linearly with the offset in energy between the Au Fermi level and the highest occupied molecular orbital as de...

Fractional factorial split-plot designs are widely used when it is impractical to perform fractional experiments in a completely random order. When there too many subplots per whole plot, or few plots, with replicated settings of the plot factors preferred. However, such an important study undeveloped literature. This paper considers WP from viewpoint clear effects. We investigate sufficient an...

In some experiments, the levels of factors are difficult to change; then fractional factorial split-plot (FFSP) designs suitable for selection. an FFSP design, divided into two classes—the whole plot (WP) and subplot (SP) factors. selection WP can affect that SP factors, which attracts much attention Paying more a new optimality criterion selecting such is proposed. The robustness proposed meth...
