What is Cathode Ray Tube ?

-

 Display Devices: 

Display devices are also known as Output devices. A commonly used output device in a graphics system is Video Monitor. The operations of most video monitors is based on the Cathode Ray Tube Design. 

Cathode Ray Tube [CRT]

CRT: Simplest version of CRT consists of a gas-filled glass tube in which two metal plates that is Cathode and Anode have placed. When a large voltage is placed across the electrodes, the Neutral Gas inside the Gas Tube Ionize into conducting plasma, and the current will flow as electrons travel from Cathode to the other side.

CRT is a type of Display Device. CRT are special electronic vacuum tubes that use a focused electron beam to Display Images. 
Where Cathode Ray Tubes are Used?
Television.
Computers.
Oscilloscopes.
Radar Display.
In video games Equipment.
What is inside Cathode Ray Tubes?
A CRT has a negatively charged terminal (i.e., Heated Filament). The filament is contained inside a vacuum with a glass tube. Filament: Coil of wire inside the cylindrical cathode structure. Inside CRT a beam of electrons is allowed to flow from filament into the vacuum. Accelerating Anode is then used to speed up the movement of the electrons.  The fast-moving electrons fly through the tubes vacuums, hitting the phosphors coated screen and making it glow.
How heat is supplied to CRT?
By directing the current through a coil of wire called filament i.e., inside the cylindrical structure.
Role of Focusing System in CRT
It is needed to force the electron beam to converge into a small spot as it strikes the phosphor.  Otherwise, electrons would repel each other and the beam would spread out as it approaches the screen.
What is inside Cathode Ray Tubes?
How Cathode Ray Tubes display output on the screen?
Whatever you see on the screen is the combined effect of all the electron light emission. A spot of light is produced on the screen by transfer of the CRT beam energy to the phosphor.  When the electrons beam collides with the phosphor coating, they are stopped and their K.E. is absorbed by the phosphor. Part of the energy is converted by friction into heat energy. After a short time, the excited phosphor electrons begin dropping back to their normal ground state giving up extra energy as a small quantum of light energy.

 Cuckoo Search Algorithm - Metaheuristic Optimization Algorithm What is Cuckoo Search Algorithm? Cuckoo Search Algorithm is a Meta-Heuristic Algorithm. Cuckoo Search Algorithm is inspired by some Cuckoo species laying their eggs in the nest of other species of birds. In this algorithm, we have 2 bird Species.  1.) Cuckoo birds   2.) Host Birds (Other Species) What if Host Bird discovered cuckoo eggs? Cuckoo eggs can be found by Host Bird.  Host bird discovers cuckoos egg with Probability of discovery of alien eggs.  If Host Bird Discovered Cuckoo Bird Eggs. The host bird can throw the egg away. Abandon the nest and build a completely new nest. Mathematically, Each egg represent a solution and it is stored in the host bird nest. In this algorithm Artificial Cuckoo Birds are used. Artificial Cuckoo can lay one egg at a time. We will replace New and better solutions with less fit solutions. It means eggs that are more similar to host bird has opportunity to de...

 Local Binary Pattern Introduction to Local Binary Pattern (LBP) Q. What is Digital Image? A. Digital images are collections of pixels or numbers ( range from 0 to 255).  Q. What is Pixel? A. Pixel is the smallest element of any digital image. Pixel can be categorized as Dark Pixel and Bright Pixel. Dark pixels contain low pixel values and bright pixels contain high pixel values. Q. Explain Local Binary Pattern (LBP)? A. Local binary pattern is a popular technique used for image processing. We can use the local binary pattern for face detection and face recognition. Q. What is LBP Operator? A. LBP operator is an image operator. We can transform images into arrays using the LBP operator. Q. How LBP values are computed? A. LBP works in 3x3 (it contain a 9-pixel value ). Local binary pattern looks at nine pixels at a time. Using each 3x3 window in the digital image, we can extract an LBP code. Q.

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.
