 What are the benefits of Process Control? The benefits of controlling or automating process are in a number of distinct area in the operation of a unit or chemical plant. Safety of workers and the community around a plant is probably concern number one or should be for most engineers as they begin to design their processes. Chemical plants have a great potential to do severe damage if something goes wrong and it is inherent the setup of process control to set boundaries on specific unit so that they don’t injure or kill workers or individuals in the community.

 

    Difference between Circuit Switching and Packet Switching     Circuit Switching Packet Switching Circuit switching is more reliable. Packet switching is less reliable. circuit switching there are 3 phases:- i) Connection Establishment.  ii) Data Transfer.  iii) Connection Released. In Packet switching directly data transfer takes place. Circuit switching is not convenient for handling bilateral traffic. Packet switching is suitable for handling bilateral traffic. In circuit switching, each data unit know the entire path address which is provided by the source. In Packet switching, each data unit just know the final destination address intermediate path is decided by the routers. Circuit Switching does not support store and forward transmission Packet Switching supports store and forward transmission In Circuit switching, data is processed at source system only I

    Difference between Lossy Compression and Lossless Compression     Lossy Compression Lossless Compression Lossy compression has more data-holding capacity. Lossless Compression has less data-holding capacity than Lossy compression technique. Lossy compression is the method which eliminate the data which is not noticeable. While Lossless Compression does not eliminate the data which is not noticeable. In Lossy compression, Data’s quality is compromised. But Lossless Compression does not compromise the data’s quality. In Lossy compression, A file does not restore or rebuilt in its original form. While in Lossless Compression, A file can be restored in its original form. Lossy compression reduces the size of data. But Lossless Compression does not reduce the size of data. Lossy compression is used in Images, audio, video. Lossless Compression is used in Text, images

    Data Parallelisms And Temporal Parallelisms     Data Parallelisms Temporal Parallelisms Same task are performed on different subsets of same data. Different task are performed on the same data. Synchronous computation is performed. Parallel computation is performed. Is a parallelization across multiple computing environment As three people Work in the common time it is called temporal Parallelisms Amount of parallelization is proportional to the input size. Amount of parallelization is proportional to the number of independent tasks is performed. As there is only one execution thread operating on all sets of data, so the speedup is more. As each processor will execute a different thread or process on the same or different set of data, so speedup is less. It is designed for optimum load balance on multiprocessor system. Here, load balancing depends upon on the e

  PLC based Multi-channel Fire Alarm System Nowadays, securing one’s property and business against fire is becoming more and more important. Monitoring commercial and residential areas all-round is an effective method to reduce personal and property losses due to fire disasters. Automatic fire alarm system is widely deployed in those sites recent years. Large numbers of small fire detectors should report their information to the control center of a building or a block. This project is design and implementation of a fire alarm system using the PLC which operates the entire system. Any signal from each detector at any level is detected and monitored using monitoring system. The appliance system has components like buzzer for alarming and motor pump to stop the fire. Relay driver to make switch on/off relay according to PLC output. The entire system is controlled by PLC. The PLC is programmed in such way by using ladder diagrams. From the project done, the system can detects smoke, heat e

  Input Variable And Output variable Input Variable This variable shows the effect of the surroundings on the process. It normally refers to those factors that influence the process. An example of this would be the flow rate of the steam through a heat exchanger that would change the amount of energy put into the process. There are effects of the surrounding that are controllable and some that are not. These are broken down into two types of inputs. Manipulated inputs Disturbances Manipulated inputs:- variable in the surroundings can be control by an operator or the control system in place.  Disturbances:- inputs that can not be controlled by an operator or control system. There exist both measurable and immeasurable disturbances. Output variable SISO MIMO Single input-Single Output (SISO):- for one control(output) variable there exist one manipulate (input) variable that is used to affect the process  Multiple input-multiple output(MIMO):- There are several control (output) variable

  Time Programmed Sun Tracking Solar Panel Time Programmed Sun Tracking Solar Panel project uses an 8051 family microcontroller and the motor is motivated by an interfacing an integrated circuit as the microcontroller is not capable of controlling the requirements of the power of the motor. Furthermore, this project can be developed by using a real-time clock to track the sun. This helps in keeping the necessary position of the solar panel even if the power is disturbed for some time Time Programmed Sun Tracking Solar Panel project uses a solar panel which is fixed to a stepper motor to track the sun so that full sunlight is made incident upon the solar panel at any time of the day. This is best compared to the light detecting method that may not always be correct. The solar panel is used to convert solar energy to electrical energy is very famous, but due to the moving of the sun from east to west, the solar panel may not be able to produce ideal energy. To overcome this problem, this

  Raspberry Pi 3.0 hardware interface Raspberry Pi 3 have a 40-pin header connector that provides access to the GPIO pins and some other signals. The header provides access to 26 GPIO pins as well as 5V, 3.3V, ground, and some specialized pins for an ID EEPROM function. The 26 GPIO pins can be individually configured as inputs or outputs, and use 3.3V logic levels where a HIGH logic level is represented as nominally 3.3 volts and a LOW by zero volts. They cannot tolerate higher voltages (like 5 volts) without being damaged. Unconnected inputs typically have an undefined logic level. Pullup or pulldown resistors can be used to force unconnected pins to a high or low level, respectively. This is often done in hardware using external resistors, but can also be done in software. Pins GPIO2 and GPIO3 have fixed pullup resistors on the board, while the other GPIO pins can be configured in software whether to provide a pullup or pulldown resistor (or none). Functions beyond basic digital I/O

  Dusk to Dawn Lighting Switch or   Lighting Switch from Sunset to Sunrise This sunset to sunrise lighting switch or Dusk to Dawn Lighting Switch is designed to control the light illuminated on the LDR sensor. The resistance of the LDR sensor changes with the change in intensity of light falling on LDR. This sensor output is given to IC 555 timer connected in bistable mode. The output of the IC 555 timer is used to control the prompting of load through a TRIAC. Hence, this circuit switches on the load in the sunset and switches off the load in the sun rise automatically. The sunset to sunrise lighting switch or Dusk to Dawn Lighting Switch project is used where the light will continue on only from sunrise to sunset (dusk to dawn). Nowadays, the electricity cost is very high and it is advisable to use electricity carefully. The applications of this project mainly include where more electricity is required in the night time like highways, complexes, colleges, parks, and industries. The p
