A microprocessor is an electronic component that is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together.
A microprocessor is an electronic component that is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together. Some microprocessors in the 20th century required several chips. Microprocessors help to do everything from controlling elevators to searching the Web. Everything a computer does is described by instructions of computer programs, and microprocessors carry out these instructions many millions of times a second. [1]
Microprocessors were invented in the 1970s for use in embedded systems. The majority are still used that way, in such things as mobile phones, cars, military weapons, and home appliances. Some microprocessors are microcontrollers, so small and inexpensive that they are used to control very simple products like flashlights and greeting cards that play music when you open them. A few especially powerful microprocessors are used in personal computers.

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.

2. Decoder
The decoder is a logic circuit that indentifies each
combination of the signals present at its input.
If the input to the decoder had ‘n’ lines, the decoder
will have 2n output lines.
Eg, if n = 2, the no. of output lines = 2n = 22 = 4.
The two lines can assume four combinations of input
signals – 00, 01, 10, 11; with each combination
identified by the output lines 0 to 3. If the input is 11,
the output line 3 will be at logic 1 and other will
remain at logic 0. This is called decoding.
Er. Sulav Paudel | MSc
3. Decoder
Various types of decoders are available, eg., 3 to 8, 4
to 16, etc.
In general decoders have enable lines too. The
decoder will not function unless enable lines are
activated.
A 2-to-4 Binary Decoders
Er. Sulav Paudel | MSc
4. 74LS138 Binary Decoder
If the input has three binary lines, then the output
lines would be 8.
74LS138 Binary Decoder
Er. Sulav Paudel | MSc
5. 74LS138 Binary Decoder (cont.)
Er. Sulav Paudel | MSc
74LS138 can be used to decode 3 address lines to enable
up to 8 memory chips (each of its output can be used to
enable a different chip).
All 8 outputs are not asserted when the enable input is
not asserted.
Only one output is asserted when enable input is
asserted, and the output asserted depends on the A, B, C
selection inputs (one output for each possible
combination).
Sometimes an external logic gate may be used in
conjunction with the 74LS138 to perform decoding using
more than 3 address lines.
8. Memory Address Decoding
The binary decoder requires only 3 address lines, (A0 to
A2) to select each one of the 8 chips (the lower part of the
address), while the remaining 8 address lines (A3 to A10)
select the correct memory location on that chip (the
upper part of the address).
Having selected a memory location using the address
bus, the information at the particular internal memory
location is sent to a common “Data Bus” for use by the
microprocessor.
This is of course a simple example but the principals
remain the same the same for all types of memory chips
or modules.

9. Encoder
The encoder is a logic circuit that provides the
appropriate code (binary, BCD, etc.) as output for
each input signals.
The process is reverse of decoding.

10. Address Decoding using 3 * 8 Decoder in 8085
Microprocessor
Interface 2K bytes of memory to 8085 with memory
address 8000H. (Using logic gates and decoder)
Solution:
2K = 2048 = 211
The total address lines required will be A10 to A0.
Write the 8000H, starting addressing in the table
below. The ending address can be found as follows:
A15 A14 A13 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0
1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
1 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1
Er. Sulav Paudel | MSc
11. In this state, 11 bits are used for 2K bytes of memory.
It will be minimum value when A10 to A0 lines are
zero and when A10 to A0 lines all are high, it will be
maximum value. So maximum value in HEX is
87FFH which is the ending address.
Er. Sulav Paudel | MSc
12. Address decoding using simple NAND gate
decoder
Thus A15 to A11 = ‘1 0 0 0 0’, these lines are used to
select the memory chip.

14. Address Decoding using 74LS138 Decoder
Er. Sulav Paudel | MSc
Interface 64K (eight 8K * 8 bits) byte block of
memory with the physical address in the range
F0000H to FFFFFH
Solution:
8K = 213 bytes in each EPROM
16. Address Decoding using 74LS138 Decoder
Er. Sulav Paudel | MSc
The most significant hexadecimal digit must be F to
address the 8 EPROMS.
Hence, address lines A16 – A19 may be used to
enable the 138 decoder (so that CE signals are only
generated if A16 – A19 are all asserted)
18. Address Decoding using 74LS138 Decoder
Er. Sulav Paudel | MSc
The address pins of each EPROM (Memory) must be
connected to the 13 least significant address lines in
order to address the 213 (=8K) bytes in each EPROM.
