In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...

the article presents explanation and analysis of plotinus’ abstraction theology. in this theology he tries to get negative knowledge of the god. the meaning of the negation is neither of pure negation or privation but it is based on abstraction which purifies and abstracts one concept from else to attain the exact and true meaning of it. accordingly, this method of theology is the same as the r...

Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...

Representation and abstraction are two of the fundamental concepts computer science. Together they enable “high-level” programming: without programming would be tied to machine code; a representation, it pure mathematical exercise. begins with an abstract structure seeks find more concrete one. Abstraction does reverse: starts structures abstracts away. While formal accounts representation easy...
