Found Objects: A View From a Room [Bits Versus Electrons]

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...

EMISSION-LINE OBJECTS FROM A PRELIMINARY UKST OBJECTIVE PRISM SURVEY

A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...

Recognising Polyhedral Objects from a Single Perspective View

This paper considers the problem of recognising 3D polyhedral objects from a single perspective image. A hypothesis-verification paradigm based on a local shape representation is presented. In the framework, 2D vertices interpreted as the projection of a trihedral vertex which is a 3D spatial vertex with three line emanating from the tip are employed as seed features for model invocation and hy...
