flexibility as an ability to respond to changing circumstances is one of the vital characteristics of the natural and built environment. during the contemporary era, diversity of methods relating the architectural flexibility execution are suggested. but along with contemporary conceptual approaches toward pluralism and uncertainty, it seems that the multiplicity of approaches toward flexibilit...

Dynamism was originally defined as the proportion of online versus offline orders in the literature on dynamic logistics. Such a definition however, loses meaning when considering purely dynamic problems where all customer requests arrive dynamically. Existing measures of dynamism are limited to either (1) measuring the proportion of online versus offline orders or (2) measuring urgency, a conc...

In the areas of application integration, mobility, and agent technology, dynamism is an increasingly desirable quality. However, deploying dynamism is problematic due to constraints on and limitations of the applications and middleware used in such distributed systems. In order to realize dynamism in t...

The traditional view that proteins possess absolute functional specificity and a single, fixed structure conflicts with their marked ability to adapt and evolve new functions and structures. We consider an alternative, "avant-garde view" in which proteins are conformationally dynamic and exhibit functional promiscuity. We surmise that these properties are the foundation stones of protein evolva...
