Oscillator is a mechanical or electronic device works on the principle of oscillation i.e. a periodic fluctuation between two things based on changes in energy. It is of two types; linear oscillators and non linear oscillators. The wave shape and amplitude are determined by the design of the oscillator circuit and choice of component values.

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.

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. TUNED COLLECTOR OSCILLATOR
• Figure shows the circuit of tuned
collector oscillator . Tuned collector
oscillation is a type of transistor LC
oscillator where the tuned circuit (tank)
consists of a transformer and a
capacitor is connected in the collector
circuit of the transistor. Tuned collector
oscillator is of course the simplest and
the basic type of LC oscillators.
6. BACKGROUND
• An oscillator is a circuit that outputs a repetitive electronic signal i.e. a sine
wave.
• The Colpitts oscillator is known for using a capacitor voltage divider as its
feedback source
• Advantages include:
• Frequency stability.
• A simple and robust design.
7. BACKGROUND
• For oscillation to occur the Barkhausen criteria must be met.
• Loop Gain
• Phase Shift must equal zero
• Magnitude equal to unity
• Realistically the magnitude will be greater than 1
• Determine if criteria is satisfied by checking the loop gain at the frequency of
oscillation
8. • This is the output signal
By noting the # of squares
We found that the
Frequency is 9KHZ
and the output voltage
200 v
9. HARTLEY OSCILLATOR
•The Hartley oscillator is an
electronic oscillator circuit in
which the oscillation frequency is
determined by a tuned circuit
consisting of capacitors and
inductors, that is, an LC oscillator.
11. PHASE SHIFT OSCILLATOR
• The frequency of oscillations is given by f0=1/2piRCroot6
R1=R2=R3=R
C1=C2=C3=C
• Circuit Operation.
• Feedback fraction, m=Ei/Eo
• Advantage.
• Disadvantage.
13. WIEN BRIDGE OSCILLATOR
The wien bridge oscillator is the standard oscillator circuit for all frequencies in the range of
10Hz to about 1MHz. It is the most frequently used type of audio oscillator as the output is free
from circuit fluctuations and ambient temperature. The wien bridge circuit originally
developed by Max Wien in 1891 for the measurement of impedances.
15. Advantage:
1. It gives constant output.
2. The circuit works quit easily.
3. The overall gain is high because of two transistors.
4. The frequency of oscillations can be easily changed by using a
potentiometer.
Disadvantage:
1. The circuit requires two transistors and large number of components.
2. It cannot generate very high frequencies.
Belongs to resonant oscillator class because they use an LC resonant circuit to determine the frequency
Unlike the Hartley oscillator which uses an inductor voltage divider
