This document discusses computer architecture and organization. It defines architecture as the attributes visible to the programmer, like instruction set and data representation, while organization refers to the operational units and interconnections that implement the architecture. Examples of architectural design issues include whether there is a multiply instruction, while organizational issues could be whether multiplication is done in hardware or software. The architecture may not change often but the organization does as technology advances to improve performance and speed.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

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. • Architecture is those attributes visible to the programmer The attributes that have
direct impact on the logical execution of a program
• Examples of architectural attributes are
Instruction set, number of bits used for data representation, I/O mechanisms,
addressing techniques.
• Architectural design issue
e.g. Is there a multiply instruction?
• It focuses on what to do?
• It deals with high level issues
Computer Architecture
3. • Computer Organization refers to the operational units and their interconnections that
realize the architectural specifications
• Organizational attributes include - Control signals, interfaces, memory technology.
• Organizational issue - E.g. Is there a hardware multiply unit or is it done by repeated
addition? ( decision—speed, cost, physical size)
• It focuses on how to do?
• It deals with low level issues
• The architecture may not change for many years but the organization changes with the
change of technology. This means that the same software can be used on different
models of the computer, only the hardware changes to make the system improve in
performance and speed.
Computer Organization
4. • We can represent a number in the form
+- S X B+-E
This number can be stored in a binary word with three fields:
• Sign: plus or minus
• Significand S
• Exponent E
Floating point formats
5. • The leftmost bit stores the sign of the number (0 = positive, 1 = negative).
• The exponent value is stored in the next 8 bits.
• The representation used is known as a biased representation.
• A fixed value, called the bias, is subtracted from the field to get the true exponent
value. Typically, the bias equals (2k - 1 - 1), where k is the number of bits in the binary
exponent.
6. • To simplify operations on floating-point numbers, it is typically required that they be
normalized.
• A normal number is one in which the most significant digit of the significand is
nonzero.
• For base 2 representation, a normal number is therefore one in which the most
significant bit of the significand is one.
• Thus, a normal nonzero number is one in the form
1.bbb…b x 2+-E
• where b is either binary digit (0 or 1). Because the most significant bit is always one, it
is unnecessary to store this bit; rather, it is implicit.
7. • The biased exponent is used to store negative exponents.
• It has advantages over 2s compliment representation in performing bitwise
comparison of 2 floating point numbers for equality.
• E.g
(22.75)10
(10110.11)2
1.011011 x 24
E = e + 127 (28-1 - 1 = 127)
= (131)10
= (10000011)2
0 10000011 011011 00000000000000000
