Function-described graphs (FDGs) have been introduced very recently as a representation of an ensemble of attributed relational graphs (ARGs) for structural pattern recognition 1, 2]. In this paper, the relationship between FDGs and Random Graphs 3] is analysed and the synthesis process of FDGs is studied, whereas the matching process between FDGs and ARGs is discussed elsewhere 4]. Two procedu...

DEFINITION Definitions are given in an attempt to identify phenomena and to delineate examples from non-examples. Expertise is consensually defined as elite, peak, or exceptionally high levels of performance on a particular task or within a given domain. One who achieves this status is called an expert or some related term, such as virtuoso, master, maven, prodigy, or genius. These terms are me...

Follicular unit extraction (FUE) is one of the widely practiced minimally invasive follicular harvesting techniques employed during hair transplantation. FUE technique has an advantage of utilising lower occipital area and supra-auricular region as a safe donor area described by Unger, in addition to the standard occipital donor area used in strip method (follicular unit transplant). Despite it...

in wireless channel the noise has a zero mean. this channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. the averaging process will reduce the effect of the noise in the decision variable that will approa...

A new variable-width window is presented and compared with several other windows, both of variable and fixed widths. The comparison focuses on sensitivity and dynamic range. The equivalent noise bandwidth or ENBW (or rather, its reciprocal) is used as a proxy for the first; maximum sidelobe level and high-frequency roll-off in the Fourier transform, for the second. The new window can access any...

Introduction Diabetes mellitus till recently has beeen divided into two main types-the 'juvenile' and 'maturity onset'-on the basis of the age at onset, bodyweight, susceptibility to ketosis and response to insulin and oral therapy. Lawrence (1951) described a rare variety of lipo-atrophic diabetes characterized by earlier age of onset, loss of subcutaneous fat, rarity of ketosis and high insul...

Growth data and longitudinal data in general are often of an ordinal nature. For example, developmental stages may be classified into ordinal categories and behavioral variables repeatedly measured by discrete ordinal scales. Consider the data set presented in Table 15.1. This table contains information on marijuana use taken from five annual waves (1976–80) of the National Youth Survey (Elliot...

15q11-13 chromosome region contains five breakpoints (BP1-BP5). Chromosomal rearrangements are common in this region. The microdeletion of BP1-BP2 region represents the 15q11.2 microdeletion syndrome associating with variable phenotype. We investigated a ten years old boy with hypotony. His motoric functions, speech and intellectual development were delayed. He suffered from epilepsy and showed...
