1 Abstract This paper aims to codify the vocabulary used for discussing the marketing and distribution channels used by software companies. Many of these patterns will exist inside companies but are not explicitly recognised, they exist only as tacit knowledge or embedded in practice. The vocabulary presented here is part of a larger pattern language by the same author. The patterns presented h...

Distributed systems are being constructed by composing a number of discrete components. This practice is particularly prevalent within the Web service domain in the form of service process orchestration and choreography. Often, enterprise systems are built from many existing discrete applications such as legacy applications exposed using Web service interfaces. There are a number of architectur...

This paper presents a pattern that provides a structure for implementing distribution using AOP — aspect-oriented programming. The main goal is to achieve better separation of concerns avoiding tangled code (code with different concerns interlacing to each other) and spread code (code regarding one concern scattered in several units of the system). Therefore, system modularity, and hence, maint...

well-known seismic design codes have offered an alternative equivalent static procedure for practical purposes instead of verifying design trials with complicated step-y-step dynamic analyses. such a pattern of base-shear distribution over the building height will enforce its special stiffness and strength distribution which is not necessarily best suited for seismic design. the present study, ...

population density and spatial distribution of thrips tabaci lindeman on seven soybean varieties (williams, tellar, sahar, dpx, l17, sari and zane) and one genotype (ks3494) were studied in tehran region, during 2007. the highest population density of the thrips per leaf was recorded on dpx and on ks3494 (0.810.05 and 0.800.05, respectively). the lowest population density was observed on l17 ...

In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...

epidemiology is the study of disease distribution and factors determining or affecting it. likewise, endodontic epidemiology can be defined as the science of studying the distribution pattern and determinants of pulp and periapical diseases; specially apical periodontitis. although different study designs have been used in endodontics, researchers must pay more attention to study designs with h...
