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.

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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
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.

Electromagnetism
• Electricity and magnetism are different facets of
electromagnetism
– a moving electric charge produces magnetic fields
– changing magnetic fields move electric charges
• This connection first elucidated by Faraday, Maxwell
• Einstein saw electricity and magnetism as frame-
dependent facets of unified electromagnetic force
3. UCSD Physics 10
Spring 2008 3
Magnetic fields from electricity
• A static distribution of charges produces an electric
field
• Charges in motion (an electrical current) produce a
magnetic field
– electric current is an example of charges (electrons) in motion
4. UCSD Physics 10
Spring 2008 4
Electromagnets
• Arranging wire in a coil and running a current
through produces a magnetic field that looks a lot
like a bar magnet
– called an electromagnet
– putting a real magnet inside, can shove the magnet back
and forth depending on current direction: called a
solenoid
5. UCSD Physics 10
Spring 2008 5
Induced Current
• The next part of the story is that a changing
magnetic field produces an electric current in a
loop surrounding the field
– called electromagnetic induction, or Faraday’s Law
6. UCSD Physics 10
Spring 2008 6
The Electromagnetic Connection
• A changing magnetic field produces an electric field, and a
changing electric field produces a magnetic field.
• Electric and Magnetic fields can produce forces on charges
• An accelerating charge produces electromagnetic waves
(radiation)
• Both electric and magnetic fields can transport energy
– Electric field energy used in electrical circuits, e.g., released in
lightning
– Magnetic field carries energy through transformer, for example

Electromagnetic Radiation
• Interrelated electric and magnetic fields traveling through space
• All electromagnetic radiation travels at c = 3108 m/s in
vacuum – the cosmic speed limit!
– real number is 299792458.0 m/s exactly

What’s “Waving” in EM waves?
• What medium transports sound waves?
– Can there be sound waves in the vacuum of outer space?
• What medium transports water waves?
• What medium transports radio waves?
• A topic of considerable debate in the late 1800’s and early
1900’s
• Led to the concept of the “luminiferous ether” – an invisible
“jello” that was thought to vibrate electromagnetically
• Experiments that sought this ether didn’t find it!
• This was quite a surprise
Electromagnetic waves travel through empty space!

Uses of Electromagnetic Waves
• Communication systems
– One-way and two-way
• Radar
• Cooking (with microwaves)
• Medical Imaging (X rays)

electromagnetic radiation…

The Electromagnetic Spectrum
• Relationship between frequency, speed and
wavelength
f ·l = c
f is frequency, l is wavelength, c is speed of light
• Different frequencies of electromagnetic radiation
are better suited to different purposes
• The frequency of a radio wave determines its
propagation characteristics through various media
