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.

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.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Statics is the part of mechanics which deals with forces acting on
bodies at rest.
The weight of the body, the tension of a string, the load and the
reaction are the different names of forces that are used in statics.
Any force can be represented in magnitude and direction by aAny force can be represented in magnitude and direction by a
straight line with an arrow head. The beginning of the line represents
the point of application of the force. The arrow head represents the
direction of the force. The magnitude of the force is given by the
length of the line drawn to scale.
14. Scalar and Vector quantitiesScalar and Vector quantitiesScalar and Vector quantitiesScalar and Vector quantities
Physical quantities which have magnitude only are called
scalar quantities. (e.g) Mass,Volume, Speed
Physical quantities which have both magnitude and direction
are called vector quantities. (e.g)Velocity, Momentum, Force

If two forces acting at a point are represented in magnitude
and direction by the two adjacent sides of a parallelogram
drawn from that point, their resultant is given in magnitude
and direction by the diagonal of the parallelogram drawn
through that point.through that point.
19. Cont….
Consider two forces P and Q acting at a point O with an
angle θ between them as shown in the figure.The forces P
and Q are represented in magnitude and direction by the
sides OA and OB of a parallelogram OACB.The diagonal OC
gives the resultant of two forces P and Q in magnitude andgives the resultant of two forces P and Q in magnitude and
direction. From C draw a perpendicular to meet OA
extended at D.
21. Lami’s theorem
Let P, Q and R be three forces acting at a point O. Under the
action of three forces, the point is at rest. Let α, β and γ be the
angles opposite to the forces P, Q and R respectively.
By Lami's theorem

23. Moment of a forceMoment of a forceMoment of a forceMoment of a force
The turning effect of the force acting on a body about an axis or point
is called moment of force.
It is common experience that in opening or closing a door, the force
we apply rotates the door about its hinges.This rotating effect is
known as the moment of force.known as the moment of force.
Moment of force is also equal to the product of the magnitude of the
force and the perpendicular distance of the line of action of the
force from the axis of rotation.
27. Couple:Couple:Couple:Couple:
Two equal and opposite parallel forces acting at different
points in a body constitute a couple.
A body acted upon by the couple will rotate the body in
clockwise direction or anti-clockwise direction.
Steering wheel and pedals of bicycles are the examples forSteering wheel and pedals of bicycles are the examples for
couple, where the two forces are equal but acting in opposite
direction.

Consider two equal forces Fand F acting on the arm AB. Let
O be the mid point of the arm .
The forces F and Fare acting in opposite direction as shown in
the figure, they constitute a couple.
Then Moment of couple or torque = F xAB.Then Moment of couple or torque = F xAB.
If the forces acting on the body have the same line of action
then the moment becomes zero.
The torque is maximum when the forces are at right angles
to the arm i.e.) θ=90º.
Note:Torque is a force that tends to cause rotation
