The document discusses various components of computer arithmetic units including half adders, full adders, ripple carry adders, and carry look ahead adders. It also covers binary addition algorithms like Booth's algorithm. Memory types like RAM and ROM are compared, with RAM being volatile and allowing both read and write access while ROM is non-volatile and only allows read access. Truth tables and circuit diagrams are provided for half adders, full adders, and adders used in binary addition.
An adder is a digital logic circuit in electronics that implements addition of numbers. In many computers and other types of processors, adders are used to calculate addresses, similar operations and table indices in the ALU and also in other parts of the processors. These can be built for many numerical representations like excess-3 or binary coded decimal

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.

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.

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.

4. Half Adder
• A half adder is a type of adder, an electronic
circuit that performs the addition of numbers.
• The half adder is able to add two single binary
digits and provide the output plus a carry
value.
• It has two inputs, called A and B, and two
outputs S (sum) and C (carry).
5. Truth Table
A (input) B (input) C (output) S (output)
0 0 0 0
1 0 0 1
0 1 0 1
1 1 1 0
Half Adder truth table:
7. Full Adder
• Full Adder is the adder which adds three inputs
and produces two outputs.
• The first two inputs are A and B and the third
input is an input carry as C-IN.
• The output carry is designated as C-OUT and the
normal output is designated as S which is SUM.
• A full adder logic is designed in such a manner
that can take eight inputs together to create a
byte-wide adder and cascade the carry bit from
one adder to the another.
10. • Logical Expression for SUM:
= A’ B’ C-IN + A’ B C-IN’ + A B’ C-IN’ + A B C-IN
= C-IN (A’ B’ + A B) + C-IN’ (A’ B + A B’)
= C-IN XOR (A XOR B)
= (1,2,4,7)
• Logical Expression for C-OUT:
= A’ B C-IN + A B’ C-IN + A B C-IN’ + A B C-IN
= A B + B C-IN + A C-IN
= (3,5,6,7)
12. Ripple carry adder/ 4 Bit binary adder
• In Digital Circuits, A Binary Adder-
Subtractor is one which is capable of both
addition and subtraction of binary numbers in
one circuit itself.
• The operation being performed depends upon
the binary value the control signal holds. It is
one of the components of the ALU (Arithmetic
Logic Unit).
