چکیده

Teacher: Can you solve this problem? (Gives student paper with 4 – 1 8 written at the top.) Student: (Writes 3 8 as answer). Three-eighths. I subtracted 1 from 4, and then kept the denominator, 8, the same. Teacher: Suppose you had four large brownies and you ate one eighth of one brownie. How many brownies would you have left? Student: (Pauses, then draws four rectangles, partitions one of the rectangles into eight pieces, and shades one of the pieces.) Three and seven eighths (writes 3 8).

Topographies of Hate: Islamophobia in Cyberia

Islamophobia’s occurrence in any particular country has little do with the presence of Muslim; it is possible to be Islamophobic when there are virtually no Muslim around. This because the lack of Muslims is filled by the surplus of Islamophobic representations. This surplus of representations is now increasingly reliant on the internet. There are many studies reporting on Islamophobia on the i...

Using both Binary and Residue Representations for Achieving Fast Converters in RNS

In this paper, a new method is introduced for improving the efficiency of the Residue Number System, which uses both binary and residue representations in order to represent a number. A residue number system uses the remainder of the division in several different modules. Conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

استفاده از تئوری مدارهای الکتریکی جهت شناسایی کریدورهای مهاجرتی بین پناهگاه‌های حیات وحش موته و قمشلو در استان اصفهان

Modeling of ecological connectivity across landscape is important for understanding a wide range of ecological processes. Modeling ecological connectivity between habitats and incorporating these models into conservation planning require quantifying the effect of spatial patterns of landscape on the degree of habitats connectivity. Recently, concepts from electrical circuit theory have been ad...

Investigating Different Graph Representations of Semantics

Combinatory Categorial Grammar is a generic approach to the mechanical understanding of language, where movement is minimised in favour of using combinators such as B (composition) and T (type lifting) to clearly define in which ways various constituents can refer to each other. Taking the tree languages induced by the syntactic derivations and connecting the various leaves linked through the s...
