On Hereditary Coreflective Subcategories of Top
Let A be a topological space which is not finitely generated and CH(A) denote the coreflective hull of A in Top. We construct a generator of the coreflective subcategory SCH(A) consisting of all subspaces of spaces from CH(A) which is a prime space and has the same cardinality as A. We also show that if A and B are coreflective subcategories of Top such that the hereditary coreflective kernel o...

متن کاملthe impact of explicit instruction of top-down reading strategies on reading comprehension of intermediate efl learners
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
Subcategories of topological algebras
In addition to exploring constructions and properties of limits and colimits in categories of topological algebras, we study special subcategories of topological algebras and their properties. In particular, under certain conditions, reflective subcategories when paired with topological structures give rise to reflective subcategories and epireflective subcategories give rise to epireflective s...
متن کاملVisual Subcategories
This thesis introduces the concept of visual subcategories. Many image understanding tasks such as object detection and image classification are formulated as binary classification problems, where the positive examples are instances (bounding boxes or images) of a specific object or scene category, and negative examples are background patches or images. Due to large intra-class variation in the...
