Neighborhoods and neighborhood sequences play important roles in several branches of pattern analysis. In earlier papers in Z only certain special (e.g. periodic or octagonal) sequences were investigated. In this paper we study neighborhood sequences which are either ultimately periodic or allow at every neighborhood to do nothing at no cost. We give finite procedures and descriptive theoretica...

Soft clays are problematic soils as they present high compressibility and low shear strength. There several methods for improving in situ conditions of soft clays. Based on the geotechnical problem's geometry characteristics, may require reinforcement to restrain instability construction settlements. Granular columns reinforced by geosynthetic material widely used reduce settlements embankments...

Random tilings are interesting as idealizations of atomistic models of quasicrystals and for their connection to problems in combinatorics and algorithms. Of particular interest is the tiling entropy density, which measures the relation of the number of distinct tilings to the number of constituent tiles. Tilings by squares and 45 rhombi receive special attention as presumably the simplest mode...

Negative staining of isolated nuclear envelopes by phosphotungstate shows that the nuclear pores are octagonal rather than circular. Pores of the same shape and approximately the same width, 663 +/- 5 A, were demonstrated in the newt, Triturus, the frog, Rana, and the starfish, Henricia. The outer and inner diameters of the annulus associated with each pore are respectively greater and less tha...

Fractal array antennas are multiband arrays having ultra wide band and space filling facility. But Side lobe levels and large number of antenna elements are the major designing challenges of these arrays. In this paper, design and analysis of octagonal fractal array antenna is investigated with Morse-Thue fractal density tapering technique (MTFDT). Due to the proposed technique, a remarkable im...

Clobber is a new two-player board game. In this paper, we introduce the oneplayer variant Solitaire Clobber where the goal is to remove as many stones as possible from the board by alternating white and black moves. We show that a checkerboard configuration on a single row (or single column) can be reduced to about n/4 stones. For boards with at least two rows and two columns, we show that a ch...

“broussonetia papyrifera” (chinese mulberry) pollen is an important source of allergens in regions surrounding shanghai, china. to identify and purify major allergens from “b. papyrifera” pollen that reacted with serum antibodies from sensitized patients, “b. papyrifera” pollen was defatted, dried, and extracted proteins were separated using sp cationic exchange or q anionic exchange columns. s...

The cyclic loading performance of bamboo double-jointed components different column base connection types was investigated through reversed tests and finite element analysis. Test results indicated that the connections played an important role in failure modes engineered columns: for encased steel plate connection, main mode tensile fracture scrimber section at bottom cladding plate; a slotted-...
