This paper deals with a new class of image models called mosaic models that view an image as a random pattern and model it by an appropriate planar process. There are several different kinds of image models in use. Mandelbrot, [l] models irregular and fragmentary natural patterns by Brownian surfaces (Fig. 1). Wong [2], H assner [3], and others model images by two-dimensional random fields. Mat...

Vertebrate Central Pattern Generators The central and peripheral nervous systems in vertebrates contain many types of central pattern generators (CPGs) that generate and control various rhythmic movements. These CPGs control many important functions, including different forms of locomotion, such as swimming, walking, running, and flying, and non-locomotor processes and behaviors, such as breath...

Fujifilm’s third generation full field digital mammography (FFDM) system, ASPIRE Cristalle, is based on Fujifilm’s unique and innovative technologies that achieve optimum image quality at very low patient dose. These outcomes are made possible by a new detector technology that uses a hexagonal close pattern (HCP) architecture, coupled with analytical and adaptive image processing that automatic...

We propose an indirect approach to the generation of a two-dimensional quasiperiodic (QP) pattern in convection and similar nonlinear dissipative systems where a direct generation of stable uniform QP planforms is not possible. An eightfold QP pattern can be created as a broad transient layer between two domains filled by square cells (SC) oriented under the angle of 45 degrees relative to each...

this study focuses on the effect of social and cultural determinants on generation gap in tehranian families in 2011. the purpose of this study is to determine effective factors on generation gap in tehranian families, analytical and empirical patterns and be surveyed by related theories and effective factors. the research was prepared by questions including whether there is a relationship betw...
