Methods AND MY ACHIVEMENT

What is Numerical Method ?

A numerical method is a complete and definite set of procedures for the solution of a problem, together with computable error estimates. The study and implementation of such methods is the province of numerical analysis. "numerical methods."

Types of Numerical Methods 1 .Bisection method 2. Newton Rapshon method (Newton’s Iteration

method) 3. Iteration method 4. Newton’s forward interpolation formula 5. Newton’s backward interpolation formula 6. Gauss Seidel Method 7. CURVE FITTING

ApplicationsUsually used in computer science for root algorithm. It is used to determine profit and loss in the

company. Used for Multidimensional root finding.Solving practical technical problems using scientific

and mathematical toolsNetwork SimulationTrain and Traffic signalWeather predictionBuild up a algorithm

Numerical Method in CRIME DETECTION :

Maths and crime: Deblurring a number plate

A short crime story• Rana robs a bank

• Escapes in a getaway car

• Pursued by police

SOLUTION Find a model of the blurring process Blurring function gOriginal image f

• Blurring formula• Inverting the formula we can get rid the

blur• BUT need to know the blurring function g

An example of Image Processing

Scientific computing

Design and analysis of algorithms for numerically solving mathematical problems in science and engineering

Considers the effect of approximations and performs error analysis

modern simulations of engineering applications

What computers can’t do

Solve (by reasoning) general mathematical problems they can only repetitively apply arithmetic primitives to input.

Solve problems exactly. Represent all numbers. Only a finite subset of

the numbers between 0 and 1 can be represented.

MY ACHIVEMENT

Championships TROPHY 2011

Badminton 

When I was in class 10, My journey was started.There are different types of game like Cricket, Football, Badminton, Basketball, Tenish etc.But I like Badminton .Mainly I love it coz it can play at night and early morning,It has a good side if anyone want to play this game in morning.He or She should get up early.it’s like phusical execise.

So for those reson I love this game

SOME PICTURES OF THIS GAME

I was attend a competition of Badminton in 2011.After my SSC exam. I got 2 month holiday.In that time Ihave no work and Read.So I Attend many badminton Tunament. Iremember a sorey ,it was the 7 tunament of badminton, and we win the chaimpian Champagne Trophy and we all join a picnic party where me and partner beer no money

2011

It’s me

THANK YOU
