PLC(Programmable Logic Controller)
Programmable Logic Controller (PLC) is an industrial computer that monitors inputs, makes decisions based on its program and controls outputs to automate a process or machine.
The automation of many different processes , such as controlling machines or factory assembly lines, is done through the use of small computers called a programmable logic controllers(PLCs).

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.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
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.
4. Digital Input (DI) Circuit
The single-end input circuit can be set to SINK or
SOURCE type by varying the wiring of the common
terminals S/S inside PLC and external common wire of
input circuits.
24VDC Single-End Input Circuit
5. Digital Output (DO) Circuit
Single-End Output Circuit
There are three kinds of output device for the single-
end output, which are relays, TRIAC and transistors.
Since the relay and TRIAC are bilateral, even when
used in single-end output, they can serve as SINK or
SOURCE output.
The transistor its SINK and SOURCE polarities are
exactly the opposite (common point Cn of SINK
output must connect to negative end of DC power).
the product model of transistor output of FBS-PLC
for SINK and SOURCE is distinct.
6. (common point Cn of SINK output must connect to negative end of DC power)
7. (common point Cn of SOURCE output must connect to positive end of DC power)
9. Power Indicator "POW〞
After the PLC is power on, with correct power
source and wiring, the〝POW〞LED indicator in
the middle of the PLC nameplate will turn on,
indicating that power supply is normal.
Operation Indicator "RUN〞
As long as the CPU is working properly, in the
STOP state, this indicator will go on and off for 2
seconds, respectively.
When it’s in the RUN state, the indicator will go on
and off for 0.25 seconds, respectively.
10. Error Indicator "ERR〞
In normal PLC operation, either in RUN or STOP
state, this indicator will not show any signal (off).
If it is on, it means that the system has an error
(e.g., WDT time-out, program error,
communication error, etc.)
If it is constantly on, please reset the power.
When the ERR indicator flashes with a 0.5 sec
interval, it means that some anomaly occurs to
PLC. At the same time, status indicators Y0~Y3
switch to serve as indications of 15 error codes
(the corresponding outputs are disabled), which
are described in the following:
11.
12. Indicator on Transmit/Receive of Built-In
Communication Port (Port0) “TX”、“RX”
The RX indicator (green) is for indication when PLC
receives external signals, while the TX indicator
(red) is for indication when PLC transmits signals.
Indicator of Input Status〝Xn〞
When external input Xn is ON, the corresponding
LED indicator Xn will be on, otherwise it will be off.
Indicator of Output Status〝Yn〞
When the Yn output of PLC is ON, its corresponding
output indicator will also be on and its external load
will be ON.
