Huygen's principle describes how each point on a wavefront acts as a secondary source of waves, and that the new wavefront is the envelope of these secondary waves. It provides a method for determining the propagation and behavior of light waves. The principle is based on assuming each point on the initial wavefront emits spherical wavelets, and the new wavefront is the envelope of these secondary waves. It can be used to understand phenomena like interference and diffraction of light.
Light waves superimpose each other and the redistribution of energy due to this can be observed in terms of well defined patterns of maxima and minima. Wherein, maxima refers to more energy and minima refers to less energy. Diffraction can also be called as interference in secondary wavelets.

POLARIZATION
Polarization is a property of waves that can oscillate with more than one orientation.
Electromagnetic waves such as light exhibit polarization, as do some other types of wave, such as gravitational waves.
Sound waves in a gas or liquid do not exhibit polarization, since the oscillation is always in the direction the wave travels.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
2. WAVEFRONT
The locus of all the particles of the medium, which at
any instant are vibrating in the same phase, is called
the wavefront.
Depending upon the shape of the source of light,
wavefront can be of the following types:
Spherical wavefront.
Cylindrical wavefront.
Plane wavefront.
3. Ray of light:
An arrow drawn normal to the wavefront and
pointing in the direction of propagation of
disturbance represents a ray of light.
4. HUYGENS’ PRINCIPLE
Huygens’ principle is a geometrical construction, which is
used to determine the new position of a wavefront at a later
time from its given position at any instant. In other words,
the principle gives a method to know as to how light spreads
out in the medium.
Huygens’ principle is based on the following assumptions:
Each point on the given or primary wavefront acts as a source
of secondary wavelets, sending out disturbance in all directions
in a similar manner as the original source of light does.
The new position of the wavefront at any instant (called
secondary wavefront) is the envelope of the secondary wavelets
at that instant.
The above two assumptions are known as Huygens’
principle or Huygens’ construction.
5. INTERFERENCE OF LIGHT
The phenomenon of non-uniform distribution of energy
in the medium due to superposition of two light waves is
called interference of light.
COHERENT SOURCES
Two independent sources of light cannot emit waves
continuously.
The waves emitted by two independent sources of light
do not have same phase or a constant phase difference.

12. TRANSVERSE NATURE OF LIGHT
Longitudinal waves: The waves, in which the particles oscillate
along the direction of propagation of the waves, are called
longitudinal waves.
Transverse waves: The waves, in which the direction of oscillation
of particles is perpendicular to the direction of propagation of the
waves, are called transverse waves.

14. LAW OF MALUS
It states that when a completely plane polarized light
beam is incident on an analyser, the intensity of the
emergent light varies as the square of the cosine of the
angle between the planes of transmission of the analyser
and the polarizer.
15. TRANSVERSE NATURE OF LIGHT
Longitudinal waves: The waves, in which the particles
oscillate along the direction of propagation of the waves,
are called longitudinal waves.
Transverse waves: The waves, in which the direction of
oscillation of particles is perpendicular to the direction of
propagation of the waves, are called transverse waves.
