Discovering the unexpected.
Visualization has been the cornerstone of scientific progress throughout history. Much of modern physics is a result of the superior abstract visualization abilities of a few brilliant men. New-ton visualized the effect of gravitational force fields in three dimensional space acting on the center of mass. And Einstein visualized the geometric effects of objects in relative and uniform accelerat...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
The Virtual Astronomical Observatory: Re-engineering access to astronomical data
TheUSVirtual Astronomical Observatorywas a software infrastructure anddevelopment project designed both to begin the establishment of an operational Virtual Observatory (VO) and to provide the US coordination with the international VO effort. The concept of the VO is to provide the means by which an astronomer is able to discover, access, and process data seamlessly, regardless of its physical ...
متن کاملDiscovering Fuzzy Unexpected Sequences with Concept Hierarchies
Sequential pattern mining is the method that has received much attention in sequence data mining research and applications, however, a drawback is that it does not profit from prior knowledge of domains. In our previous work, we proposed a belief-driven method with fuzzy set theory for discovering the unexpected sequences that contradict existing knowledge of data, including occurrence constrai...
متن کاملDiscovering Fuzzy Unexpected Sequences with Beliefs
In this paper we present a novel approach for discovering fuzzy unexpected sequences, such as certainly unexpected, almost unexpected and a little unexpected, from databases with respect to user defined beliefs. We first formalize the belief on sequences and the different types of unexpectedness, then we detail the algorithm Taufu that finds fuzzy unexpected sequences with beliefs. Our approach...
