A visual configuration, or pattern, has qualities over and above those which can be specified by designating the physical properties of each element of the pattern. The Gestalt psychologists have particularly emphasized the fact that a pattern also has organization, that it exists as an entity. This Gestalt property does not exist in the same amount for all patterns, so we speak of the "goodnes...

This paper aims to help the writers of pattern languages build better pattern languages. It focuses not on the esthetics of pattern languages, but on their structure: how patterns work together to build a system. The paper assumes that a pattern language is a designed system and, therefore, theory about system design and evolution underlies the language. In particular, the process of symmetry b...

Complimenting behavior, as a common speech act of human beings, has become an intriguing topic in linguistics and its sub-branches. Compliment responses can be seen as solutions for maintaining a balance between (1) a preference to avoid self-praise and (2) a preference to accept or agree with the compliment (Pomerantz 1978). In the present study, the definition of a compliment draws on the wor...

Background Ultrasound is the first line modality in evaluation of pelvic masses in female patients. It is helpful in detection of masses and also in determining origin of them. Tissue characterization is possible with gray scale but Doppler study is quite necessary and considers as complimentary method. Most of the time, it should be performed in vaginal US exam. Existence of vascularity and al...

We present our approach to support program understanding by a tool that generates static and dynamic analysis algorithms from design pattern specifications to detect design patterns in legacy code. We therefore specify the static and dynamic aspects of patterns as predicates, and represent legacy code by predicates that encode its attributed abstract syntax trees. Given these representations, t...

We studied the effect of nearest pattern interaction on a global pattern formation in a two-dimensional space, where patterns are to grow initially from a noise in the presence of a periodic supply of energy. Although our approach is general, we found that this study is relevant in particular to the pattern formation on a periodically vibrated granular layer, as it gives a unified perspective o...

Micro-arrays technology has marked a substantial improvement in making available a huge amount of data about gene expression in pathophysiological conditions; among the many papers and books recently devoted to the topic, see, for instance, Hardimann (2003) for a discussion on such a tool. The availability of so many data attracted the attention of the scientific community much on how to extrac...

Parametric methods first choose the form of the model or hypotheses and estimates the necessary parameters from the given dataset. The form, which is chosen, based on experience or domain knowledge, often, need not be the same thing as that which actually exists (Duda, Hart & Stork, 2000). Further, apart from being highly error-prone, this type of methods shows very poor adaptability for dynami...

Using the sampled data of a desired pattern is a common technique in pattern synthesizing of array factor (AF) of antenna arrays. Based on the obtained data matrix, Least Square Method (LSM) is used to calculate the exciting coefficient of array elements. The most important parameter, which involves the accuracy and complexity of calculation, is the sampling rate of the desired pattern. Classic...
