1) The document discusses hysteresis and eddy current losses in magnetic circuits. Hysteresis loss is due to the lagging of magnetic flux behind the magnetic field strength, while eddy current loss is caused by induced currents within the magnetic material.
2) Total iron loss in a magnetic core is the sum of hysteresis and eddy current losses. Hysteresis loss depends on the area of the hysteresis loop, while eddy current loss depends on the rate of change of flux and resistance of the material.
3) To reduce eddy current loss, magnetic cores are made of thin laminated sheets with insulation between layers, as this decreases induced currents within the core from the changing magnetic flux.

Classification of magnetic materials on the basis of magnetic momentVikshit Ganjoo
I made this presentation for my own college assignment and i had referred contents from websites and other presentations and made it presentable and reasonable hope you will like it!!!
This Presentation can be used by the Students of Engineering who Deals with the Subject ELECTRICAL MACHINES and use it for Refrence (Anyways you Guys will Copy Paste or Download it) ;)
Before approaching any kind of toroidal chokes manufacturers in India, it is better to understand cores, chokes, and losses, so that you can make a better decision about the choice of chokes you want for your application.

Transformer is a static device, hence mechanical losses (like friction loss) are absent in it. A transformer only consists of electrical losses (iron losses and copper losses).
Core Loss Or Iron Loss Or Constant loss:
Core losses are due to the magnetic properties of the material used for the construction of core.
Core is made by iron like CRGO so called iron loss.
Core loss is treated as constant at rated voltage and frequency, so called constant loss.
Eddy current loss:
The Different Types of Inductors and Their Affecting Factorselprocus
An inductor is also named as a reactor, coil and choke. It is a two terminal electrical component used in various electrical and electronic circuits. An inductor is used to store energy in the form of a magnetic field. Learn the different types of inductors and their affecting factors and have a wide variety and important applications in electronics.
Iron losses in ferromagnetic enclosures of gas-insulated transmission lines u...Power System Operation
The enclosure of AC gas-insulated transmission lines
(AC-GIL) is ordinarily made of aluminium. In HVDC
systems, it can be economically and technically
reasonable to manufacture the enclosure of GIL from
steel. To check the feasibility to operate such DC-GIL
even under AC the relevant losses in the steel enclosure
must be known.
The present paper compares three different methods to
determine the specific iron losses of steel when exposed
to magnetic fields with power frequencies. The iron
losses as a function of the magnetic field strength are
measured with a pipe sample in a coaxial conductor
arrangement, a pipe sample in a toroidal core test and
with relevant strips in an Epstein frame. The results
from the three test methods are found to be in close
agreement. By calculating the iron losses in a GIL with
steel enclosure the reduction of the transmission capacity
is estimated when changing from DC to AC operation.
An induction is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor therefore does not require mechanical commutation, separate-excitation or self-excitation for all or part of the energy transferred from stator to rotor, as in universal, DC and large synchronous motors. An induction motor's rotor can be either wound type or squirrel-cage type.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

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.
