Design and Manufacturing of Press Tools for Compressor ShellINFOGAIN PUBLICATION
The role of Sheet Metal has become very prominent with the use of Press Tools. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.The project deals with Compressor Shell Lower Housing. The Compressor Shell holds all the parts of the compressor in pre-defined location for the compressor to fool proof. The component should be freed from burrs and also to dimensional accurate. The outcome component is been inspected in the Quality department so as to check the Dimensional accuracy is been achieved.

The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users.

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.

3. Rolling
The main purpose of this rolling process is to reduce the thickness of the metal
plates. In the forming processes, metal is not removed.
Production of flat plate, sheet, and foil in long length at high speeds and
with good surface finish
11. Q 1 A Copper strip of 200 mm width and 30 mm thickness is
to be rolled to a thickness of 25 mm. The roll of radius 300
mm rotates at 100 rpm. The average shear strength of the
work 180 Mpa. The roll strip contact length and roll forces
are
Solution :- width 200 mm H1 = 30 mm H2 = 25 mm
R = 300 mm N = 100 rpm Shear Stress = 180 Mpa
we know L = (R*h)1/2 = (5*300)1/2 = 38.73 mm
shear stress = Force / area
Force = shear stress * Area
F= 180*200*38.73 = 1.39 MN
12. Q 2 An annealing copper strip 228 mm wide and 25 mm
thick is rolled to a thickness of 20 mm in one pass. The roll
radius is 300 mm and the roll rotate at 100 rpm. Calculate
the Roll force and Power required in the operation? Take
shear stress 26000N/mm2.
Answer:- W = 228 mm h1 = 25 mm h2 = 20mm
R= 300 mm N = 100 rpm
F= L*W*Shear stress
L = (R*h)1/2 = (300*5)1/2 = 38.72 mm
True strain of strip = ln(h1/h2)= ln(25/20)=0.223
F = 38.72*228*26000=229.53 MN
Power = 2*3.14 *N*T/60 = 2*3.14*100*229.53*38.72/60
Power= 46.53kw
13. Q 3 Rolling very thin strips of mild steel requires
a) Large diameter Rolls
b) Small diameter rolls
c) High speed rolling
d) Rolling without a lubricant
(b)
Q 4 In Rolling process separating force can be decreased by
a) Reducing roll diameter
b) Increasing roll diameter
c) Providing back up Roll
d) Increasing the friction between roll and metals
(a)
14. Q 5 The thickness of a plate is reduced from 30
mm to 10 mm by successive cold rolling passes
using identical rolls of diameter 600 mm. Assume
that there is no changes in width. If the coefficient
of friction between the rolls and the work piece is
0.1, the minimum number of passes required is
Sol:- h1=30 mm h2 = 10 mm h= h2-h1 = 20 mm
D = 600 mm R = 300 mm coefficient of
friction(µ) = 0.1
hmax = µ2 R = 0.1*0.1*300 = 3 mm
Number of Passes = htotal / hmax = 20/3 = 7 pass
15. Q 6 which of the following assumption are
correct for Rolling
1. The material is plastic
2. The arc of contact is circular with radius
greater than radius of roll
3. Coefficient of friction is constant over
the arc of contact and act in one
direction through out the arc of contact.
Select the correct answer
a) 1 and 2 b) 1 and 3
c) 2 and 3 d) 1,2 and 3 (a)
16. Q 7 In one setting of rolls in a 3 high rolling mill
one gets
a) One reduction in thickness
b) Two reduction in thickness
c) There reduction in thickness
d) Two or three reaction in thickness depending
upon setting (b)
