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.
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.

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. Introduction
BHEL is the largest engineering and manufacturing enterprise in
India in the energy related infrastructure sector today. BHEL was
established more than 40 years ago when its first plant was setup in
Bhopal ushering in the indigenous Heavy Electrical Equipment
Industry in India a dream which has been more than realized with a
well recognized track record of performance it has been earning
profits continuously since1971-72.BHEL caters to core sectors of
the Indian Economy viz., Power Generation's & Transmission,
Industry, Transportation, Telecommunication, Renewable Energy
Defence etc. The wide network of BHEL's 14 manufacturing
division, four power Heavy Electricals Limited (B.H.E.L.) is the
largest engineering and manufacturing enterprise in India.
4. Products
• Thermal power Plants
• Nuclear power Plants
• Gas based power Plants
• Hydro power Plants
• Boilers (steam generator)
• Boiler Auxiliaries
• Hydro generator
• Steam turbine
• Gas turbine
• Hydro turbine Solar Photo voltaics.
5. STEAM TURBINE
A steam turbine works on the principle
of conversion of High pressure & temperature
steam into high Kinetic energy , thereby giving
torque to a moving rotor.
7. High pressure turbine (H.P. Turbine)
High pressure and temperature fluid at the
inlet of the turbine exit as lower pressure and
temperature fluid. The difference is energy
converted by the turbine to mechanical
rotational energy, less any aerodynamic and
mechanical in efficiencies incurred in the
process. Since the fluid is at a lower pressure
at the exit of the turbine than at the inlet, it is
common to say the fluid has been “expanded”
across the turbine.
10. ADVANTAGES OF H.P TURBINE BLADE
• Ability to utilize high pressure and high
temperature steam.
• High efficiency.
• High rotational speed.
• High capacity/weight ratio.
• Smooth, nearly vibration-free operation.
• No internal lubrication.
• Oil free exhausts steam.
11. Low Pressure Turbine
• LP turbine is designed to be a dual flow
turbine. Steam enters the center of the
turbine from the crossover pipe and flows
across the reaction blading in two opposite
directions. This configuration reduces axial
thrust on the turbine and allows for a smaller
turbine installation. On ships where space is
not a concern, a single flow turbine is used.
13. Low Pressure Turbine blade
Titanium alloys offer high strength to
intermediate temperatures at a density almost
half that of steel and nickel-based superalloys.
As a result, they have been adopted widely in
the fan and compressor stages of the gas
turbine for both disc and blade applications..
• LP blade is larger than HP & IP.
14. INTERMEDIATE PRESSURE TURBINE
• Intermediate pressure turbine having more
pressure then L.P turbine and lass than the high
pressure turbine(H.P) . Its blade is larger than
high pressure turbine.
15. Blade of intermediate pressure turbine
• The size of blades of I.P steam turbine is larger
than H.P steam turbine , but smaller than L.P
steam turbine.
16. Control Valves
• Steam inlet valves perform one of two
functions, protection or control.
• Steam inlet control valves regulate the flow
and/or the pressure of steam through the
turbine. Their position, from closed to fully
open, is determined by the turbine electronic
controlled.
18. Cutting method
• Plasma cutting:- Inert gas is blown at high speed
out of a nozzle; at the same time an electrical arc
is formed through that gas from the nozzle to the
surface being cut, turning some of that gas
to plasma.
• CNC cutting machine:-Based on CNC programs.
19. • Flame cutting:-A common propane/air flame
burns at about 2,000 °C (3,630 °F), a
propane/oxygen flame burns at about
2,500 °C (4,530 °F), and an acetylene/oxygen
flame burns at about 3,500 °C (6,330 °F).
20. Conclusion
• Summer Training gives the idea of ‘general
awareness in steam turbine manufacturing’, &
its process. Its provides practical idea to
manufacturing several components of turbine.
