Problem:

Residue Method's Code in C and MatLab | Congruential Method Code

Details:

We need the generate random numbers using Residue method. How do we generate that random number?

Solution:

Random Number generation code in C using Residue Method:

/**
    Code    : Residue/Congruential Method in C
    Author  : Maniruzzaman Akash<manirujjamanakash@gmail.com>
**/

#include<stdio.h>
int main(){
    //r(i) = (ar(i-1) + b ) modulo m
    int random[1000], maxLimit, i, n;
    printf("First Random Number or seed : ");
    scanf("%d", &random[0]);

    printf("What is the maximum limit : ");
    scanf("%d", &maxLimit);

    printf("How many eandom Number you want to generate : ");
    scanf("%d", &n);

    int a = 19, b = 1;

    printf("\nRandoms are : ");
    for(i = 1; i <= n; i++){
        //
        random[i] = ( a * random[i - 1] + b ) % maxLimit;
        printf("%d ", random[i]);
    }
    printf("\n");
}

Random Number generation code in Matlab using Residue Method:

a=input('Please Enter the value of a : ');
b=input('Please Enter the value of b : ');
m=input('Please Enter the value of m : ');
r=input('Please Enter the value of seed or r : ');


totalNumber = input('Number of Random Numbers want to generate : ');
R = zeros();

for i = 1:totalNumber
    r = mod(a*r +b, m);
    R(i) = r;
    fprintf('%4.0f ', R(i));
end
fprintf('\n');

Formula/Algorithm of residue

    //r(i) = (ar(i-1) + b ) modulo m

Simple One Line Instruction, nothing to say here.

What is Blue Whale Game ? Why people suicide?

noreply@blogger.com (Maniruzzaman Akash) — Tue, 10 Oct 2017 05:41:00 +0000

Todays most common question is Blue Whale:

What is Blue Whale Game ? Why people suicide by playing this Blue Whale Game?

What is Blue Whale and who invented the Blue Whale Game ?

Blue Whale Game is a Russian game called Blue Whale Chalanger. It is a social media hacking app and managed by administrators and who played that game they are forced to do some daily tasks 50 day period by black mailing their accounts and private things.

Blue Whale invented a Russian.
Philipp Budeikin, a 21-year-old former psychology student who was invented the game in 2013.

What is Exactly the Blue Whale Game?

The dangerous game named "Blue Whale" involves brainwashing in little teenagers for a period of 50 days, forcing them to complete tasks by watching/seeing some horror movies to waking at strange hours, and to do self harming.

How Blue Whale Administrator black mail the Blue Whale Users?

The administrator may has all the Facebook and other links of that user and then they black mail the user.

They first Black mail the user by their Facebook and other social account and they forced to install the Blue Whale game and to play. In todays, they make a facebook app called Popcorn Carnival and make trap by this app.
At first, they say to do some simple tasks. And the tasks are easy for first day to twenty or thirty day.
After thirty day, this Blue Whale games becomes very vulnerable situation. Like they take Nude photos of that user and blackmail him/her by that. Then they told to do some ridiculous things. Like, cutting hands, belly's and so on.
The user start to torture their body by forcing black mailing using Blue Whale.
Final attack is in 50 days, they commit the user to suicide by Blue Whale. Then if the user is a normal teenagers, then it is not possible to him/her to avoid that and they take suicide attempt.

What say Philipp Budeikin for the Blue Whale Game?

Philipp Budeikin is really a physio. Philipp Budeikin says- "he thinks of his victims as 'biological waste' and told police that they were really 'happy to die' and he was 'cleansing society'.
His main theme is cleaning the society.
Philipp Budeikin was arrested and sent to Kresty Prison in 2016 for killing some innocent teenage girls by playing this Blue Whale game.

Blue Whale Result effects in many countries:

The Blue Whale game is not a fake game at all. People of all over the world are killing themselves by playing this game. The most are the teenagers.

Russia :
In recent, their are almost 50 teenage girls suicided in Russia by playing this Blue Whale game.

India:
In recent, their are almost 20 teenage girls/boys suicided in India by playing this Blue Whale game.

Brazil:
Almost 10 are suicided in Brazil by playing this game.

Bangladesh:
Yesterday(9 October) a girl in Bangladesh suicides for the Blue Whale game and took suicide. It is not so much sure that she was a Blue whale gamer. But peoples now think that.

Other Countries:
In other countries there are also many teenagers are taking suicide attempt for this Blue Whale game.

Advice for teenagers for Blue Whale Game:

Don't join this trap anyway. Don't open any unseen link in the facebook or others. Don't join it never. They will black mail you, then you can't do anything. If it happens to you, just tell your parents or police and they'll take that, don't be afraid this crazy Social App.

See the physio at a glance of this Blue Whale game's inventor:

Philipp Budeikin

Starting Conversation Of Blue Whale Game Before Starting with Admin:

You: I want to play the game.
Admin: Are you sure? There is no way back
You: Yes. What does that mean ? There is no way back?
Admin: You can’t leave the game once you begin
You: I’m ready
Admin: Carry out each task diligently and no one must know about it. When you finish the task, you have to send me a photo of that as proof.
You: And if I wanna get out from this game ?
Admin: I have all your information, they will come after you (that’s mean if you left this game in middle they will kill your family, that’s why most of players under pressure commits suicide)

I don't why people need to do that. It's a totally stupid work. Emotionally they are black mailed by the admin. by this Blue Whale.

First 30 days task of Blue Whale Game:

Tasks of Blue Whale Game

The Last 20 days tasks of Blue whale game are more dangerous. They are-

Last 20 days tasks of Blue Whale Game

The peoples who committed to suicide for Blue Whale(just few):

Peoples who have committed suicide for Blue Whale Game

So, final alert is please stay away from this Blue Whale Stupid game.

Which Free blog is better- Wordpress or Blogger

noreply@blogger.com (Maniruzzaman Akash) — Sat, 07 Oct 2017 02:58:00 +0000

From few a days, I've got some question about Wordpress and Blogger. User's has asked me -

Which free blog site is better? Wordpress or Blogger?

Now, it's time to give a clear and concise answer in my sense- what is better wordpress or blogger.

Answer is definitely Blogger.

Why Blogger site is better than WordPress:

Tell me, why you want to create a site in blogger or in WordPress?

Share your ideas..
Make a picture of yours to internet and
Wanna earn some money for your hard work for a blog.

Number Three is may be a so much important term to all. We'll work in anything, we must expect something in return. We must expect some money for our hard work in a blog at all.

So, why wordpress.com free site is not better from blogger?

First of all, in wordpress.com there is no Adsense approve of them. Adsense doesn't work with WordPress. Adsense is a big ad publisher hosted by google. Every blogger's aim is to approved by Adsense and Adsense must return you a big money. You can't imagine that I've a free blog and after 7 try's I've got Adsense approve and now earn monthly 150$. There's only 30 posts and daily visitor is 1000.
Second, In some countries adsense is not approved so easily. Or your site needs high quality content to approve by adsense. You must try some other ad sites who can give you a promised money like A-ads, Pop Ads, Pop Cash, Propeller Ads, Revenue Hits, Ad-Maven and so many others Ad publisher's site. And most of the other ad publishing site needs to allow a script tag or iframe tag in the theme or widget. Wordpress doesn't allow these type of codes. Wordpress doesn't allow iframe, script tags. Without these tags, you can't earn money from any Blogging site. And hopefully blogger gives you the power of embedding anything from internet.
Third, If you learn some HTML code, you can modify your site's theme easily. But in Wordpress.com that can't be possible so easily.
Fourth, you may think wordpress theme is looking nice and blogger's theme isn't. Ok friends, then try to Gooyaabi Templates. There are huge templates in that site for blogger and you can add that template in your site.

Benefits of Wordpress.com site:

Search Engine Friendly
A nice and easiest Admin Panel.

So, after this comparison race, what will you give them a score. Definitely give Blogger a 5 of 5 and WordPress.com can get 5 of 1. We can make our site also search Engine friendly by download a Search Engine Friendly Blogger theme.

Thanks for staying with me, and now if you want to learn how to make an awesome website in Blogger in 10 minutes with custom template, then Read the article -

What are the characteristics of Digital IC's?-Solution

noreply@blogger.com (Maniruzzaman Akash) — Sun, 17 Sep 2017 16:53:00 +0000

Question:

What are the characteristics of Digital IC's?

Answer: [Answer from RP Jain's book]

There are various characteristics of digital IC's to measure their performance. The issues are-

Speed of operation,
Power of dissipation,
Figure of merit,
Fan-out,
Current and voltage parameters,
Noise immunity / Noise Margins,
Operating temperature range,
Power Supply requirements,
Flexibility available.

Digital IC

The details of these criteria's are-

1) Speed of operation:
The speed of a digital circuit is specified in terms of the propagation delay time. If the propagation delay time is lower, the speed of the IC is higher.

2) Power of dissipation:
This is the amount of power dissipated in an IC. It is determined by the current, I_CC, that it draws from the V_CC supply, and is given by V_CC * I_CC.
I_CC is the average value of I_CC(0) and I_CC(1). This power is specified in milliwatts.

3) Figure of merit:
The figure of merit of a digital IC is defined as the product of speed and power. The speed is specified in terms of propagation delay time expressed in nanoseconds.

Figure of merit = propagation delay time (ns) * power (mW)

It is specified in pico joules (ns * mW = pJ).
A low value of speed-power product is desirable. In a digital circuit, if it is desired to have a high speed, low propagation delay time, then there is a corresponding increase in the power dissipation and vice versa.

4) Fan Out:
Fan out is the number if similar gates which can be driven by a gate. High fan-out is advantages because it reduces the need for additional drivers to drive more gates.

5) Current and voltage parameters:

High level input voltage(V_lH) : This is the minimum input voltage which is recognized by the gate as logic 1.
Low level input voltage(V_lL) : This is the maximum input voltage which is recognized by the gate as logic 0.

6) Noise immunity:
The input and output voltage levels are defined above are shown in figure. Stray electric and magnetic fields may induce unwanted voltages, known as noise, on the connecting wires between logic circuits. This may cause the voltage at the input to a logic circuit to drop below V_lH or rise above V_lL and may produce undesired operation.

Noise immunity

So, the circuit's ability to tolerate noise signals is referred to as the noise immunity, a quantitative measure of which is called Noise Margin.

7) Operating temperature range:
The temperature range by which a IC functions properly must be known. The accepted temperature ranges are: 0 to 70 degree Celsius for consumer and industrial applications and -55 degree Celsius to 125 degree Celsius.

8) Power supply requirements:
The supply voltage and the amount of power required by an IC are important characteristics required to choose the proper power supply.

9) Flexibility available:
Various flexibilities are available in different IC logic families and these must be considered while selecting a logic family for a particular job.Some of the flexibilities are:

The breadth of the series
Popularity of the series
Wired logic capability
Availability of complement outputs
Type of output.

How to redirect one page URL to another page URL by javascript

noreply@blogger.com (Maniruzzaman Akash) — Fri, 26 May 2017 19:46:00 +0000

Question:

How to redirect one page URL to another page URL by JavaScript?

Solution:

We can use PHP for redirecting one page to another. But it is simple to redirect multiple url redirection from one URL to other URL by JavaScript easily.

See the Simple pseudo code of javascript page redirection,

<script>
if(window.location.href == 'old_url')
{
    window.location.href="new_url";
}


//More url's redirect
if(window.location.href == 'old_url2')
{
    window.location.href="new_url2";
}
</script>

And real life example for that is:

<script>
if(window.location.href == 'https://test.com')
{
    window.location.href="https://another.com";}


//More url's redirect
if(window.location.href == 'https://test.com/new-post')
{
    window.location.href="https://another.com/duplicate-post";}
</script>

Find the integral for the above function get upper limit and lower limit from user--

f = @ (x) 0.2 + 25*x - 200*(x^2) + 675*(x^3) -900*(x^4) + 400*(x^5);

In this problem, you can take divide the polynomial in mutiple parts. In this solution, this upto in 10 parts in array. You can do it more as your need.

f = @ (x) 0.2 + 25*x - 200*(x^2) + 675*(x^3) -900*(x^4) + 400*(x^5);


n = input('Enter how many parts do you want? : ');
a = input('Enter lower limit : ');
b = input('Enter Upper Limit : ');

part = (b - a)/n;
array = [0,0,0,0,0,0,0,0,0,0,0];


if(n == 2)
    array(1) = a;
    array(2) = b;

Simpson's 1/3 Code in Matlab

Simpson's 1/3 rules Code implementation in MatLab

Simpson's 1/3 rule

From Book of Steven Chopra -

Aside from applying the trapezoidal rule with finer segmentation, another way to obtain a more accurate estimate of an integral is to use higher-order polynomials to connect the points.

For example,

If there is an extra point midway between f(a) and f(b), the three points can be connected with a parabola.

If there are two points equally spaced between f(a) and f(b), the four points can be connected with a third-order polynomial. The formulas that result from taking the integrals under these polynomials are called Simpson’s rules.

Simpson’s 1/3 Rule to find integral is :

Simpson's 1/3 rules Code implementation in MatLab

Question is:

f (x) = 0.2 + 25x - 200x2 + 675x3 - 900x4 + 400x5

from a 5 0 to b 5 0.8. Recall that the exact integral is 1.640533. Find the Integral and exact error

Solution in normal numerical mathematics of Simpson's 1/3 rules:

f(0) = 0.2

f(0.4) = 2.456

f(0.8) = 0.232

Therefore,above figure equation can be used to compute

I = (0.8 - 0) * (0.2 + 4*(2.456) + 0.232)/6

= 1.367467

which represents an exact error of

E = 1.640533 - 1.367467

= 0.2730667

Et = 16.6%

Solution in matlab coding of Simpson's 1/3 rules:

% Author : Maniruzzaman Akash
% Code   : Simpsons 1/3 Rules Code in Matlab Implementation

% Function 
f = @ (x)  .2+ 25*x - 200*x^2+675*x^3-900*x^4+400*x^5;

disp('Press 1 for set values ');
disp('Press 2 for see results ');
disp('Press 0 for exit the program ');
disp('---------------------------------');

isInputGiven = false;
while(1)
    choose = input('Give your choose option: ');
    if(choose == 1)
        a = input('Enter lower limit : ');

        b = input('Enter upper limit : ');
        
        exact_integral = input('Enter exact integral : ');

        x0 = a; 
        x1 = (b-a)/2; 
        x2 = b; 


        fx0 = feval(f,x0);
        fx1 = feval(f,x1);
        fx2 = feval(f,x2);

        integral = ((fx0 + (4*fx1) + fx2)/6 * (b-a));
        isInputGiven = true;
    end;
    
    if(choose == 2)
        if(isInputGiven == true)
            integral_output = sprintf('Integral is = %0.5f',integral);
            disp(integral_output);
            
            exact_error = ((exact_integral - integral)/exact_integral) * 100 ;
            exact_error_output = sprintf('Exact Error = %0.5f',exact_error);
            disp(exact_error_output);
        end;
    end;
    
    if(choose == 0)
        disp('Exiting the code..');
        exit(0);
    end;
end;

Output Of the above code will look like:

Simpson 3/8 is just as the problem. Just Equation is the different for that math and change in equation in code also.
Thanks.
