Key size Diffusion and Confusion Conclusion References Hill Cipher Introduction Invented by Lester S. Hill in 1929‚ the Hill cipher is a polygraphic substitution cipher based on linear algebra. Hill used matrices and matrix multiplication to mix up the plaintext. To counter charges that his system was too complicated for day to day use‚ Hill constructed a cipher machine for his system using a series of geared wheels and chains. However‚ the machine never really sold. [1] Hill’s

PROPERTIES OF DISCRETE TIME FOURIER TRANSFORMS ABSTRACT In mathematics‚ the discrete Fourier transform (DFT) converts a finite list of equally-spaced samples of a function into the list of coefficients of a finite combination of complex sinusoids‚ ordered by their frequencies‚ that has those same sample values. It can be said to convert the sampled function from its original domain (often time or position along a line) to the frequency domain. INTRODUCTION The input samples are complex numbers

------------------------------------------------- Please read before you come for the next lesson Additional Notes on significant figures When we use an equipment to take measurement‚ it is important to be honest when reporting a measurement‚ so that it does not appear to be more accurate than the equipment used to make the measurement allows. To achieve this‚ we can control the number of significant figures used to report the measurement. When we look at a number‚ its first significant

Poor seed viability and germination (11.5℅) restricts the use of seeds in multiplication (Rekha et al.‚ 2005). Indiscriminate over exploitation from natural source to meet the growing

Mathematical Report: Knowledge and Understanding 2 This report aims to examine the historical and cultural development of mathematics and how it stands today with the current decimal system and modern curriculum. Exploring the differences between numeracy and mathematics and also the recent introduction of functional skills‚ I shall also discuss the significance of zero and place value and how links and generalisations can be made between mathematical concepts. Furthermore‚ this report shall

pairs(m‚n) where m and n are integers‚ n is not 0 (n ≠ 0)‚ and "~" is the equivalence relation defined by (m1‚n1) ~ (m2‚n2) if‚ and only if‚ m1n2 − m2n1 = 0. In abstract algebra‚ the rational numbers together with certain operations of addition and multiplication form a field. This is the archetypical field of characteristic zero‚ and is thefield of fractions for the ring of integers. Finite extensions of Q are called algebraic number fields‚ and the algebraic closure of Q is the field of algebraic numbers

I was able to play “multiplication war” with the students. We have also done task cards‚ where the students go around the room and write down multiplication

It was a bright sunny Wednesday afternoon and I was walking towards my car. I got out of class early and was heading home to get myself ready to spend time with my bright and intelligent students. Sometimes when I get out of class my body feels overwhelmed and tired. Perhaps it feels this way because of all the things that are going on in my life like family‚ friendship‚ relationship‚ community service‚ and homework assignments. I feel like I am very busy that I often do not have time for myself
