In this study, a numerical method was proposed to evaluate the calligraphy work called calligraphy evaluation system. Four classical chirographies of “Kaisho”, “Gyosho”, “Sousho” and “Hiragana”, and 47 characters for each chirography, were selected and analyzed by this system. The “Sumi” distribution of character was clarified from 12 directions and summarized into four parts of horizontal part...

BACKGROUND Selective pressures that occur during long-distance migration can influence morphological traits across a range of taxa. In flying insects, selection should favour individuals that have wing morphologies that increase energy efficiency and survival. In monarch butterflies, differences in wing morphology between migratory and resident populations suggest that migratory populations hav...

Abstract The three-probe method for separating the spindle rotation error and specimen form is extensively described in literature. An attractive feature its application in-process measurement. However, resulting uncertainty studied far less extensively. In this paper, an evaluation propagation uncertainty, as well reduction, given based on system transfer function (S-function). First, utilizin...

Dust is one of the environmental problems in Kerman city. Due to the major aspect of mineralogy in environmental studies, mineralogy and chemical studies of dust in different regions of the city performed by microscopic thin sections, x ray diffraction (XRD) and ICP-MS. In all areas of the city, minerals such as calcite, quartz, feldspar, pyroxene, micas, Jaffeite, gismondine and clay mineral w...

Background. Much of the sedimentary transport and depositional history of Mars may be recorded in the morphologic characteristics of the individual rocks or particles that make up its sedimentary clast population (defined as a rock fragment or grain resulting from the breakdown of larger rocks or bedrock). Measuring morphology is crucial; it retains the best record of sorting and abrasive effec...
