In this paper we study applicative theories of operations and numbers with (and without) the non-constructive minimum operator in the context of a total application operation. We determine the proof-theoretic strength of such theories by relating them to well-known systems like Peano Arithmetic PA and the system ( 0 1 -CA) <" 0 of second order arithmetic. Essential use will be made of so-called...
Unities in the processes involved in solving arithmetic problems of varying operations have been suggested by studies that have used both factor-analytic and information-processing methods. We designed the present study to investigate the convergence of mental processes assessed by paper-and-pencil measures defining the Numerical Facility factor and component processes for cognitive arithmetic ...
In this paper we compare the performance of several range arithmetic methods in evaluating problems in symbolicnumeric circuit analysis. Symbolic-numeric circuit analysis involves solving systems of linear equations in order to obtain the values of currents and voltages in a given circuit. Symbolic circuit expressions contain a large number of product terms and long chains of arithmetic operati...
While the influence of spatial-numerical associations in number categorization tasks has been well established, their role in mental arithmetic is less clear. It has been hypothesized that mental addition leads to rightward and upward shifts of spatial attention (along the "mental number line"), whereas subtraction leads to leftward and downward shifts. We addressed this hypothesis by analyzing...
High precision arithmetic can improve the convergence of Krylov subspace methods; however, it is very costly. One system of high precision arithmetic is double-double (DD) arithmetic, which uses more than 20 double precision operations for one DD operation. We accelerated DD arithmetic using AVX SIMD instructions. The performances of vector operations in 4 threads are 51-59% of peak performance...
This paper presents a new genetic approach based on arithmetic crossover for solving the economic dispatch and environmentally constrained economic dispatch problems. Elitism, arithmetic crossover and mutation are used in the genetic algorithm to generate successive sets of possible operating policies. The proposed technique improves the quality of the solution. The employed arithmetic crossove...
This paper is devoted for the design and implementation of a 32bit Arithmetic module it is used for vedic Mathematics algorithms. We have various arithmetic multiplication techniques like Urdhva, Tiryakbhyam, Nikhilam, and Anurupye has been thoroughly analyzed. A 32 x 32 bit multiplier using Urdhava Tiryakbhyam, it has been designed and using this multiplier, a MAC unit has been designed. An Ar...
[email protected] 1 , [email protected] 2 , Abstract—the most timing critical part of logic design usually contains one or more arithmetic operations, in which addition is commonly involved. Addition is a fundamental arithmetic operation and it is the base for arithmetic operations such as multiplication and the basic adder cell can be modified to function as subtractor by adding ano...
Visual Learning of Arithmetic Operations Yedid Hoshen and Shmuel Peleg HUJI A simple Neural Network model is presented for endtoend visual learning of arithmetic operations from pictures of numbers. The input consists of two pictures, each showing a 7digit number. The output, also a picture, displays the number showing the result of an arithmetic operation (e.g., addition or subtracti...
