The separation of concerns principle aims at decomposing a given design problem into concerns that are mapped to multiple independent software modules. The application of this principle eases the composition of the concerns and as such supports composability. Unfortunately, a clean separation (and composition of concerns) at the design level does not always imply the composability of the concer...

biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. the cultivation of genetically modified (gm) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. considering the fast pace of new advances in production of genetically modified crops,...

The separation of concerns is important to attain object oriented systems which can be easily evolved. This paper presents a reflective architecture which enforces the separation of concerns by allocating functional, interaction and synchronization code to different levels. A variant of collaborations (CO actions) is used to capture interactions between objects and avoids spreading the descript...

In order to improve requirements specifications, this paper presents an approach to support the separation of concerns in requirements artifacts. Our goal is to be able to represent non-functional concerns apart from the requirements they affect. We provide means to specify the composition among requirements in a noninvasive way. An Internet Banking System example is used to illustrate our prop...

Collective phenomena in strongly nonequilibrium systems interacting with electromagnetic field are considered. Such systems are described by complicated non-linear differential or integro–differential equations. The aim of this review is to show that many nonlinear collective phenomena can be successfully treated by a recently developed method called the Scale Separation Approach whose name is ...

Separation of concerns is a fundamental principle for managing conplex tasks. Previous tools for assisting in generating back-of-the-book indexes do not apply this principle as thoroughly as they might; in particular, most confuse two issues: recording where references occur in the main text, and deciding what terms should appear in the index. This paper describes a general facility for multi-l...

summed up a parallel that many health officials and journalists had noted: " Disturbing echoes of the great 1918 flu pandemic. " " The main danger of a new flu virus emerging from pigs is that it would not be recognised by the human immune system and so would result in severe infections that could quickly spread from one person to another, " The Independent noted. And there was no denying that ...

Walking has always been the most natural, the oldest, and the most essential form of transportation and is still major form of moving, hence, it plays a vital rule in urban transportation. In fact, walking is the most important tool for seeing, being seen, observing city wide daily and social activities, discovering the values and hidden attractions in urban environment, and therefore, feeling ...
