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.
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.

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.

Type of analog transmission:
1. Digital to analog conversion
2. Analog to analog conversion
7. What is digital to analog conversion?
Type of digital to analog conversion:
1.Amplitude shift keying
2.Frequency shift keying
3.Phase shift keying
8. Amplitude shift keying (ASK) : Amplitude-shift
keying (ASK) is a form of amplitude modulation that
represents digital data as variations in the amplitude
of a carrier wave.
9. Frequency shift keying : Frequency shift keying
(FSK) is a frequency modulation scheme in which digital
information is transmitted through discrete frequency
changes of a carrier signal.
10. Phase shift keying : Phase shift keying (PSK) is a
digital modulation scheme that conveys data by
changing (modulating) the phase of a reference signal.
11. ANALOG ANALOG CONVERSION
• Analog signals are modified to represent analog data.
• Also known as Analog Modulation.
• Required when BANDPASS is used.
13. Amplitude Modulation
• In AM transmission, the carrier signal is modulated so that its amplitude
varies with the changing amplitudes of the modulating signal. The
frequency and phase of the carrier remain the same. Only the amplitude
changes to follow variations in the information. The following figure
shows how this concept works. The modulating signal is the envelope of
the carrier.
14. Frequency Modulation
• In FM transmission, the frequency of the carrier signal is
modulated to follow the changing voltage level (amplitude)
of the modulating signal. The peak amplitude and phase of
the carrier signal remain constant, but as the amplitude of
the information signal changes, the frequency of the carrier
changes correspondingly.
• The following figure shows the relationships of the
modulating signal, the carrier signal, and the resultant FM
signal. FM is normally implemented by using a voltage-
controlled oscillator as with FSK. The frequency of the
oscillator changes according to the input voltage which is the
amplitude of the modulating signal.
16. Phase Modulation
• In PM transmission, the phase of the carrier signal is modulated to
follow the changing voltage level (amplitude) of the modulating
signal. The peak amplitude and frequency of the carrier signal remain
constant, but as the amplitude of the information signal changes, the
phase of the carrier changes correspondingly. It is proved
mathematically that PM is the same as FM with one difference.
• In FM, the instantaneous change in the carrier frequency is
proportional to the amplitude of the modulating signal; in PM the
instantaneous change in the carrier frequency is proportional to the
derivative of the amplitude of the modulating signal. The following
figure shows the relationships of the modulating signal, the carrier
signal, and the resultant PM signal.
18. Errors
A bit error occurs when a source sends a bit, b, and the destination
receives NOT b.
The error can take place on the link , in a switch or router along the path,
or in the source or destination (e.g. failed hardware, or bit errors in
memories).

Detecting and Correcting Errors
• When we transmit a message, we typically append a checksum to the
message.
• The checksum is calculated by performing a function over all the bits
in the message.
23. A checksum is a simple type of redundancy check that is
used to detect errors in data.
24. Sender site:
1. The message is divided into 16-bit words.
2. The value of the checksum word is set to 0.
3. All words including the checksum are
added using one’s complement addition.
4. The sum is complemented and becomes the
checksum.
5. The checksum is sent with the data.
25.
26. Receiver site
1. The message (including checksum) is
divided into 16-bit words.
2. All words are added using one’s complement addition.
3. The sum is complemented and becomes the
new checksum.
4. If the value of checksum is 0, the message
is accepted; otherwise, it is rejected.
