Abstraction and Existence

Existence, Negation, and Abstraction in the Neoplatonic Hierarchy 1

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

the plotinus’ abstraction theology

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...

Observable Sequentiality and Full Abstraction 1 Full Abstraction and Sequentiality

One of the major challenges in denotational semantics is the construction of fully abstract models for sequential programming languages. For the past fteen years, research on this problem has focused on developing models for PCF, an idealized functional programming language based on the typed lambda calculus. Unlike most practical languages, PCF has no facilities for observing and exploiting th...

Unsupervised Event Abstraction using Pattern Abstraction and Local Process Models

Process mining analyzes business processes based on events stored in event logs. However, some recorded events may correspond to activities on a very low level of abstraction. When events are recorded on a too low level of granularity, process discovery methods tend to generate overgeneralizing process models. Grouping low-level events to higher level activities, i.e., event abstraction, can be...
