What is fluid power ?
• Fluid power is the technology that deals with the
generation , control ,and transmission of power using
pressurized fluids. It can be said that fluid power is the
muscle that moves industry. This is because fluid power
is used to push , pull ,regulate or drive virtually all the
machines of modern industry.
• Fluid power is subdivided into hydraulics using a liquid
such as mineral oil or water, and pneumatics using a gas
such as air or other gases

Advantages of fluid power
• 1-Ease and accuracy of control
• By the use of simple levers and push buttons, the operator of
a fluid power system can readily start , stop speed up or slow
down and position forces that provides any desired
horsepower with tolerance as precise as one ten- thousand of
an inch
10
Ref: fluid power with applications 4th edition,
Anthony esposito
• 2-Multiplication of force
• A fluid power system (without using cumbersome gears,
pulleys , and levers) can multiply forces simply and efficiently
from a fraction of an ounce to several to several hundreds
tons of output.
11
• 3-Constant force or torque
• Only fluid power systems are capable of providing constant
force or torque regardless of peed change. This is
accomplished whether the work output moves a few inches
per hours.
12
• 4-Simplicity ,safety, economy
• In general , fluid power systems use fewer moving parts than
comparable mechanical or electrical systems. Thus , they are
simpler to maintain and operate . This ,in turn, maximize
safety ,compactness, and reliability.
13
The available Power Source for the
mechanical machines (Actuators)
• 1- Diesel engines
• 2-Electical Drive
• 3-Pnumatic actuators
• 4-Hydrulic actuators
14
• The choice of using electric, hydraulic, or
pneumatic motion systems is a
fundamental decision that affects
performance, costs, maintainability,
safety, ease of use, flexibility, and
reliability the needs of the application
and the capabilities of the technology
must be carefully evaluated—and then
balanced with a cost-benefit analysis.
15
Small note before the comparison
• As systems, neither one is better than the other.
There is no "Better", only "More suitable for a
specific purpose." Car tyres are Pneumatic...
they're full of air. Air is compre.

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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
