Speed Control of Induction Motor using Variable Frequency DriveSandeep Kaushal
Induction motor is constant speed motor at a particular frequency and consumes almost same power irrespective of load demand. Let's talk about two different load one is high load and other low load. AT low load motor is delivering the load with some current and thereby torque is maintained. If load goes high, to maintain the same speed and developed torqued, motor will draw extra current and will corresponds to more losses. If speed of motor is reduced corresponding too low load and is increased corresponding to high load, then substantial amount of power can be saved. And speed can be changed by changing the frequency of input supply.

Speed of synchronous motors can be controlled using two methods called open loop and close loop control.
Open loop contol is the simplest scalar control method where motor speed is controlled by independent frequency control of the converter.
In case of close loop self control mode, instead of controlling the inverter frequency independentaly, the frequency and the phase of the output waveform are controlled by an absolute position encoder mounted on the machine shaft giving an account of position of the rotor.

A Human Exoskeleton also known as Powered Armour, Exoframe, Hardsuit, or Exosuit, is a wearable mobile machine that can be powered by a system of motors, pneumatic, levers, or hydraulics that amplifies the force of the operator and enables them to possess superhuman strength, This project aims to design and implement an exoskeleton arm for use in the fields of rehabilitation and therapeutic application, as well as occupations requiring augmented strength. Though systems exist, past exoskeleton endeavors have led to bulky, expensive, invasive, and tethered solutions. The challenge is to build an exoskeleton system that is inexpensive, streamlined, and wireless. Our solution is unique in that it will be a low-cost, ergonomic device actuated through sensors measuring the user’s motion. Through onboard sensing, the skeleton can provide rich data, such as range of motion for use in physical therapy. This data can be used by doctors and patients to more accurately track improvement over time. With its low cost, hospitals could employ multiple devices and aid a larger audience of patients; the devices could even be used at home for physical therapy, which would dramatically increase quality of life for patients. Outside of physical therapy, this project can also extend its applications where augmented strength is applicable to physically intensive occupations, as well as search and rescue operations.
A VFD can be used to control both the speed and torque of a standard induction AC electric motor.
It varies both the frequency and voltage of the AC waveform being delivered to the motor saving money in electricity.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator.
In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor. In certain applications, such as in the transportation industry with traction motors, electric motors can operate in both motoring and generating or braking modes to also produce electrical energy from mechanical energy.

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.
