There are about 1000 species of Bats. Bat Algorithm is based on the echolocation behavior of Micro Bats with varying pulse rates of emission and loudness. All bats use echolocation to sense distance and background barriers.  Microbats are small to medium-sized flying mammals. Micro Bats used a Sonar that is known as Echolocation to detect their prey. Bats fly randomly with the velocity at the position with a fixed frequency and loudness for prey.  Q. Whats is Frequency? A. Frequency is the number of waves that pass a fixed point in unit time. Wavelength is the minimum distance between two nearest particles which are in the same phase. Here, Sound waves are used by microbats to detect prey.  Q. What is Position? A. A place where something or someone is located.  Q. What is Velocity? A. Speed of something in a given direction.  Q. What is loudness. A. Loudness refers to how soft or loud sound seems to listeners.  Q. What is pulse rate? A. Wave or vibration.  In th

Digital Image is Made up of Pixels. Pixel is the Smallest Element of an Image. A digital image is composed of a finite number of elements, each element has a particular location and value. The digital image is a 2-dimensional function. It is represented by f(x,y). Where x,y is the plane coordinates, and f is the amplitude that is the brightness of the image. The sensor is used to sense the object structure and a continuous voltage signal is generated. In order to create a digital image, we need to convert data into digital form. For this Sampling and Quantization is done. Sampling is digitizing the coordinate value. Quantization is analog to digital conversion of a sampled image to a finite number of gray level. The process of digital image formation is shown in this video. https://youtu.be/pNl-yhlp5bo

We humans, are created by God. God will smile and feel proud that my creation (God Creation -Human) creating Artificial Humans (that is Robots). we created machines first, and now we are working on its intelligence (using artificial intelligence). We are trying to create machines/robots as intelligent as humans. The only risk is that if we humans lose control over robots/machines situation will be out of control. 

If you are dealing with low-speed internet problems. Then follow these steps to increase the speed of your Airtel 4G. first, send SMS "MO" to 54321. 1.) Insert the Airtel sim in the first slot. 2.) When you will insert the sim in the first slot you will get a message. 3.) Install the Configurations setting. 4.) Install configurations. 5.) Save Settings. I tried this. And increased my speed up to 9mbps-10mbps.

In this video, we discuss how to change screen color on mouse click. We used two design elements that are screen and button. A button tag is used to create the button. Javascript is used to change the screen color on mouse click that is HTML onclick Event attribute. We accessed the design elements that are button and screen using their id. document.getElementByID. A function is created to change the screen color by accessing the screen element. How to change text color on click using JavaScript? four steps are followed for Changing text color onclick: 1.)Define your Purpose. 2.)Choose Design Elements. 3.)Coding 4.)Run the Code Save filename.html Click on Run than Launch on Chrome

There is not 100% accuracy on masked face recognition. Algorithms like the viola-jones face detection algorithm can detect masked human faces from the digital images. I applied the viola jones algorithm on MASKED human face images and it successfully detects human masked faces. Link:  https://youtu.be/bgnb8kLhoWs https://youtu.be/bgnb8kLhoWs Face Detection Systems are used for the identification of a person from digital images. The face detection system can extract the different facial features from a digital image. A set of facial features extracted from a digital image includes eyes, nose, mouth, and face region. Face recognition is a difficult task due to the different facial expressions. With the help of a face detection system presence of a human face can be detected easily. For the detection of different facial features, the Viola-Jones algorithm is used in the proposed work. To make the task more manageable, Viola-Jones requires full view frontal upright faces.

First, learn about FACE DETECTION.  Then face recognition would be an easy task for you. Because most of the computer algorithms work first on face detection after that they can recognize. First learn, how to detect humans or anything you want to detect (objects/ birds/other). When your software will be able to detect it. Then train it for recognition. I worked on Human face recognition. First, I created software for human face detection. Once your software can detect it. You can easily train it for recognition/identification.

There are already several efforts in place to leverage artificial intelligence in the fight against coronavirus. Some of these methods include automatically measuring people’s temperature in public places, diagnosing COVID-19 infections from chest x-ray scans, and using machine learning algorithms to predict the spread of the virus. 1.)

MATLAB Simulator Q . Why we are using simulation software? A. Simulation Software helps us to predict the behavior of a system (i.e., Dynamic System ).  Q. How we can use simulation software? A. We  can use simulation software to evaluate a new design, diagnose problems with an existing design, and test a system under conditions that are hard to reproduce, such as a satellite in outer space.   Q.  Who using Engineers simulation software and why?  A.  Engineers and scientists use simulation software for a variety of reasons.  Creating and simulating models is less expensive, t o  t est different designs  before building one in hardware and  to test the integration of the full design.  Q.  What is  Simulink?
