The composition of software units has been one of the main research topics in computer science. This paper addresses the composition validation problem evolving in this context. It focuses on the composition for a certain kind of units called aspects. Aspects are a new concept which is introduced by aspect-oriented programming aiming at a better separation of concerns. Cross-cutting code is cap...

A major challenge facing cloud migration is the need to change a legacy (on-premise) application’s source code so that it can better benefit from the inherit cloud computing characteristics, such as resource elasticity and high scalability. When performed manually, those changes are error-prone and may require a great effort from application developers. This paper presents a novel approach to s...

Aspect-oriented programming introduces new composition operators that offer enhanced capabilities for constructing well-modularized programs. One of its cornerstones is the introduction of 'reverse' dependency relations; instead of explicitly 'importing' composed behavior (as is e.g. the case with inheritance), the composed behavior is 'exported'. These reverse composition relations are more er...

This paper illustrates how aspect-oriented programming techniques support some tasks whose implementation using conventional object-oriented programming would be extremely time-consuming and error-prone. In particular, we have successfully employed aspects to evaluate and monitor the I/O performance of alternative data mining techniques. Without having to modify the source code of the system un...

Introduction: Cognitive linguists believe that metaphor is a cognitive phenomenon, and that what appears in language is just the aspect of cognitive phenomenon Metaphor is one of the basic interdisciplinary concepts that has been paid more attention to its fundamental role in various aspects of psychology, medicine, including cancer in recent years. Methods:. From the point of view of cognitiv...

In this paper, we examine teleoperation as a critical aspect of using mobile robotic telepresence systems. Particularly, we propose and advocate using cognitive architectures as means to ease teleoperation for novice users and to enhance social interactions.

In this paper I discuss Mark Steiner’s view of the contribution mathematics to physics and take up some questions it raises. particular, question discovery explore two aspects – a metaphysical aspect related epistemic aspect. The concerns formal structure physical world. Does world have mathematical or features constituents, what is nature these constituents? humans’ cognitive ability reach Amo...

emphasis on sustainable agriculture in iran like the other developing countries, is responsedto the adverse environmental and economic impacts of conventional agriculture. thisproblem, particularly about “greenhouse production” is considerable. the perceptions ofgreenhouse owners about the environmental, economical and social aspects of sustainableagriculture was discussed in this article. the ...

A particularly important aspect of executive functioning involves the ability to coordinate two simultaneous activities. The role of this aspect of executive functioning in adult-age differences in cognitive performance was examined in a study involving 150 adults between 20 and 91 years of age who performed the same visual-motor tracking task with three different primary tasks. The participant...

Because intelligent agents employ physically embodied cognitive systems to reason about the world, their cognitive abilities are constrained by the laws of physics. Scientists have used digital computers to develop and validate theories of physically embodied cognition. Computational theories of intelligence have advanced our understanding of the nature of intelligence and have yielded practica...
