Arduino based heartbeat monitoring system.Arkadeep Dey
Technological innovations in the field of disease prevention and maintenance of patient health have enabled the evolution of fields such as monitoring systems. Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. Heart rate is the number of times the heart beats per minute, reflects different physiological conditions such as biological workload, stress at work and concentration on tasks, drowsiness and the active state of the autonomic nervous system. It can be measured either by the ECG waveform or by sensing the pulse - the rhythmic expansion and contraction of an artery as blood is forced through it by the regular contractions of the heart. The pulse can be felt from those areas where the artery is close to the skin. This paper describes a technique of measuring the heart rate through a fingertip and Arduino. It is based on the principal of photophelthysmography (PPG) which is non-invasive method of measuring the variation in blood volume in tissue using a light source and detector. While the heart is beating, it is actually pumping blood throughout the body, and that makes the blood volume inside the finger artery to change too. This fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can be amplified and is sent to Arduino with the help of serial port communication. With the help of processing software heart rate monitoring and counting is performed. The sensor unit consists of an infrared light-emitting-diode (IR LED) and a photo diode. The IR LED transmits an infrared light into the fingertip, a part of which is reflected back from the blood inside the finger arteries. The photo diode senses the portion of the light that is reflected back. The intensity of reflected light depends upon the blood volume inside the fingertip. So, every time the heart beats the amount of reflected infrared light changes, which can be detected by the photo diode. With a high gain amplifier, this little alteration in the amplitude of the reflected light can be converted into a pulse.

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.

Interface stepper motor through Arduino using LABVIEW.
1. EXPERIMENT – 2
OBJECTIVE: Interface stepper motor through Arduino using LABVIEW.
APPARATUS USED: Arduino board, stepper motor, LABVIEW setup.
THEORY:
Introduction to LABVIEW: LabVIEW is an integrated development environment designed
specifically for engineers and scientists. Native to LabVIEW is a graphical programming language
(G) that uses a dataflow model instead of sequential lines of text code, empowering you to write
functional code using a visual layout that resembles your thought process. This means you spend
less time worrying about semicolons and syntax and more time solving the problems that matter.
Introduction to Arduino: Arduino is an open-source electronics platform based on easy-to-use
hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button,
or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing
something online. You can tell your board what to do by sending a set of instructions to the
microcontroller on the board. To do so you use the Arduino programming language (based on Wiring),
and the Arduino Software (IDE), based on Processing.
Over the years Arduino has been the brain of thousands of projects, from everyday objects to
complex scientific instruments. A worldwide community of makers - students, hobbyists, artists,
2. programmers, and professionals - has gathered around this open-source platform, their
contributions have added up to an incredible amount of accessible knowledge that can be of great
help to novices and experts alike.
Stepper Motor: A stepper motor or step motor or stepping motor is a brushless DC electric motor
that divides a full rotation into a number of equal steps. The motor's position can then be
commanded to move and hold at one of these steps without any feedback sensor (an open-loop
controller), as long as the motor is carefully sized to the application in respect to torque and speed.
Relay Driver IC: A Relay driver IC is an electro-magnetic switch that will be used whenever we
want to use a low voltage circuit to switch a light bulb ON and OFF which is connected to 220V
mains supply. Bipolar NPN transistor driver.
3. Interfacing Relay Driver with Stepper Motor:
Interface Arduino through LabVIEW:
Step 1: In LabVIEW (any version) establish the following front panel
Step 2: Establish the following block diagram.
4. Step 3: This virtual instrument:
>> Starts communication with Arduino.
>> Detects if there is a change in control knob value.
>> If there is a change it sends the new value to Arduino.
>> Else, it clears serial port Input/output register to avoid data overflow and serial port
overloading.
>> When pressing STOP, it sends “0” (brake or hold order) to Arduino.
Step 4: Arduino Code
(Attachment available)
Checks if LabVIEW sent a new value. If there is a new value, it converts it into integer byte with
the same value. This integer byte represents the delay interval used in stepping sequence. That,
the greater the delay the lower the speed and vice versa. Else, Arduino continue running the
motor at current speed. This prevents the processor from overloading the serial port and pushes it
to avoid Arduino Serial port hanging.
Calculates motor speed from its resolution and delay intervals between steps as following:
Rpm = (60 x 1000 x step angle) / (360 x (delay msec))
Rpm = (1000 x step angle) / (6 x (delay in msec))
Rpm = 300 / (delay in msec). Sends the calculated motor speed to another Serial port of Arduino
Mega to show if our code works
RESULT: Successfully running the stepper motor by interfacing Arduino with LabVIEW.
