Tachogenerators and optical encoders are used to measure rotational movement. Tachogenerators use the principle that a voltage is induced when there is relative motion between a magnetic field and conductor. Optical encoders have a light source and sensor that detect patterns on a rotating disk to provide a digital output proportional to angular position. There are two main types: absolute encoders uniquely represent a given position, while incremental encoders count lines to determine position but not uniquely.

They always sound so high tech that we hardly notice that our day-to-day lives always involve the use of sensors. From IR sensors in TV remotes to passive infrared sensors on automatic doors or LDRs for outdoor and street lightings, sensors are everywhere.
Sensors detect changes, acknowledge those changes, and produce outputs from those changes. They detect and measure qualities such as light, temperature, sound, and other types of output from the environment.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

2. Tachogenerator
• An electromechanical generator is a device capable of producing electrical power from
mechanical energy, usually the turning of a shaft.
• They are the measurement devices for measuring the shaft speed in mechanical equipment.
• One of the more common voltage signal ranges used with tachogenerators is 0 to 10 volts.
• Tachogenerators are frequently used to measure the speeds of electric motors, engines, and
the equipment they power: conveyor belts, machine tools, mixers, fans, etc.
3. Principle of Operation
The major principle for tachogenerator is that the relative motion between a magnetic field
and a conductor results the voltage in that conductor.
There are mainly two types of tachogenerator:
• A.C. Tachogenerator
• D.C. Tachogenerator
5. Construction
• An Armature is rotating type & this magnet is fixed type.
• Armature is coupled to a machine whose velocity is to be measured.
• It consists of commutator and brushes is connected to armature.
• Output is connected to Moving Coil (MC) type Voltmeter.
Operation
• When the armature is stationary there is no relative motion between the magnetic field and
the armature winding.
• Hence the output voltage is Zero
• As the armature speed increases the relative motion also increases.
• The output voltage is induced in the armature winding.
• The magnitude of this voltage is proportional to the speed of armature.
• A commutator and brush are connected in the armature to give the DC output voltage.
• This output voltage is measured with the help of moving coil voltmeter calibrated in terms of
speed.
6. Optical Encoders
• An optical encoder is an electromechanical device which has an electrical output in digital
form proportional to the angular position of the input shaft.
• It is used to measure rotational movement precisely.
• Information obtainable from an optical encoder includes direction, distance, velocity and
position.
There are two types of encoders:
1. Absolute Encoders
2. Incremental Encoders
7. Absolute Encoder
• It provides a unique binary word coded to represent a given position of the object.
• It has a light source that emits a beam of light onto photoelectric sensor called photo
detector.
• The photo detector converts the receiving light into an electric signal.
• A coded wheel is placed between the light source and photo detector.
• The coded wheel has alternating opaque and transparent sections.
8. • As the disk rotates, these patterns interrupt the light emitted onto the photo detector,
generating a digital or pulse signal output.
• The result obtained is a series of signals corresponding to the rotation of coded wheel.
• A counter is used to count these signals to determine how far the wheel is rotated.
12. Incremental Encoder
• Incremental encoders are commonly used than absolute encoders because of their simplicity
and lower cost.
• It consists of three parts:
Rotary disc ( with alternate opaque and transparent slots)
A light source
A photo detector
• Incremental encoders are used for both velocity and position measurement and is most
reliable and inexpensive.
13. • For angular measurement, it consists of a sensing shaft attached to a disk that is divided
into equal number of sectors on circumference.
• In linear type, there are equal segments along the length of travel.
• The readings are sensed by direct electrical contact with a brush or wiper or optically slit
gratings.
• It counts the lines on disk. More lines, higher resolution.
• This is expressed as pulses per revolution.
14. • There are two types of incremental encoders: i. Tachometer Type ii. Quadrature Type
• Tachometer type has one output channel and is used for velocity measurement. This is done
by looking at the pulses during a certain interval of time.
• However, the output of the single-channel encoder does not indicate direction.
• To determine direction, a two-channel, or quadrature, encoder uses two detectors and two
code tracks.
• Quadrature type have dual channels A and B; they are arranged in such a way that they are
90 degrees out of phase with each other.
• If A leads B, for example, the disk is rotating in a clockwise direction. If B leads A, then the
disk is rotating in a counter-clockwise direction.
• Therefore, by monitoring both the number of pulses and the relative phase of signals A and
B, you can track both the position and direction of rotation.
