Electricity is generated by moving a magnet near a copper wire, inducing a current. Most power plants have large magnets spun by steam turbines, which are heated by burning fossil fuels, nuclear fission, or renewable sources like wind and falling water. The generated current is sent through power lines to homes and businesses. Common renewable sources used in power generation include hydroelectric, wind, geothermal, and solar power. Each source has advantages and disadvantages related to costs, environmental impacts, and reliability.

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.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
2. Electricity by definition is electric current that is used as a power source!
This electric current is generated in a power plant, and then sent out
over a power grid to your homes, and ultimately to your power outlets.
3. The movement of charges such
as electrons is called current, and
this electrical current is what
powers household appliances.
Electric Current =
Charge Passing
Through A Given Area
-------------------------------
Time
4. An easier way to think of electric current is to picture cars going
through a Turnpike or Parkway Toll.
The cars could represent
electrons or charge, and the
toll booth could represent the
cross sectional area of the
wire at a certain point.
If you counted the number of cars or electrons, that passed through
the toll booth or a certain cross sectional area of the wire, and divided
that number by the time it took for those cars or charges to pass,
you would get the current!
5. Electric current generation - whether
from fossil fuels, nuclear, renewable
fuels, or other sources is usually
based on the:
6. In September of 1831, Michael Faraday
made the discovery of Electromagnetic Induction.
Faraday attached two wires to a disc and
rotated the disc between the opposing
poles of a horseshoe magnet creating
an electric current.
7. An electric current is not generated unless the magnetic field is moving
relative to the copper wire, or the copper wire is moving relative to the
magnetic field.
If you place a magnet and a conductor (copper wire), in a room together
there will be no electric current generated.
This is because motion, from our equation for electricity, is missing!
8. So simple electric generators found in power plants contain, magnets
and copper wire that when put into motion relative to one another
create the electric current that is sent out to homes.
The major problem in
electricity generation
Is where does the
Motion come from
that keeps the
copper wire and
magnets moving
relative to one
another.
In this case, wind power applies a force to the blades that turns them.
The spinning blades, spin an armature that turns the copper wire
relative to the magnetic field. As long as the blades spin, electricity
will be generated!
9. - AC of 60 Hz produced by generator
- Resistance losses are smallest at high voltages and low currents
10. At home, electric current
that was generated by
generators in the power
plant is used to power
electric appliances.
The electric current,
running through the
copper wire causes
the armature to spin
which is how most
motors generate
motion.
11. Where does the motion needed to keep the copper wire moving relative
to the magnetic field come from?
Wind generated
Kilronan Wind Farm In Ireland
-attains between 50 – 70% efficiency
- one windmill’s average energy
output ranges from 11.4 W/m^2 –
57 W/m^2 depending on how windy
-wind farms tend to generate between
50 and 600 Kw
- California currently produces ¾
of all the wind generated electricity
in the world.
-North Dakota with 20 times the wind potential of California has not
erected a single wind turbine
12. Wind power classes 3 (300-400 W/m2) to 7 (800-2000 W/m2) are suitable
for wind power development
13. -Wind variability must be overcome by system design
- Basic energy Storage
- Differences in pressure gradients around wind turbines affect birds
-Noise from the turbines affects people and animals
-Eyesore, the appearance of mile after mile of wind machines with
transmission lines is of concern to the public
14. Water generated - Hydroelectric
Shasta Dam In California
-Conversion from potential energy of
water to electric energy is at 80 – 90%
efficiency
-Hydroelectric projects in the United
States have rated capacities from
950 – 6480 MW
-The use of Water Power is much
greater in some other countries.
Norway obtains 99% of its electricity
from water power. Nepal, Brazil, and
New Zealand are close seconds.
15.
16. - Hydroelectricity has dropped from producing 30 % to 10% of US electricity
- Large fluctuations in output are mainly due to variable rainfall totals
17. -About 50% of the United States potential for hydroelectric energy has been
tapped. However, further advances are unlikely.
-The Wild and Scenic River Act and the Endangered Species Act have
inhibited development of some sites
-Silt collection in hydroelectric Dam storage volumes over time causes
maintenance issues, as well as environmental concerns
-The loss of free flowing streams and land due to flooding behind the dam
disturbs the life of species: eg – Salmon
- Possibility of dam failure
18. Fossil Fuels – Oil Refinery
Pasadena - Texas
Standard Large Power Plants Provide 1 Giga-watt of electric power
and releases 2 Giga-watts of thermal power as waste heat. An
efficiency averaging around 30%.
-9000 tons of coal a day
-40,000 barrels a day or one tanker a week of oil
-generates about 5.3 x 10^9 kwh/year
-powers a city of a million people
19.
20. Oil Drilling Platform
Cook Inlet, Alaska
-total world production in 1996 of
petroleum is 62,239e3 barrels / day
-an average well in the US produces
only 11 barrels / day
-In Saudi Arabia an average well
produces 9600 barrels /day
21.
22.
23. Nuclear Power
Diablo Canyon - California
-Plant electrical output 1220 MW
-Plant efficiency 34%
-There are 109 power reactors in the United States
-Produce 22% of nation’s electricity
- In France 79% of electricity comes from nuclear reactors
24.
25. -In normal operations a nuclear reactor produces some environmental
emissions. E.g.: escape of radioactive fission products through cracks and
diffusion, radioactive H3 in small amounts in discharged water
-Core meltdown are possible, but unlikely due to negative feedback and
shutdown systems
-Even after shutdown there is 7% of normal power generation still in the
reactor fuel rods. This may be sufficient enough to melt core and destroy
the reactor, if cooling water is not supplied
-A study entitled “Severe Accident Risks: An Assessment for Five US
Nuclear Power Plants” conducted by NRC in 1990, shows that for all the
109 reactors now operating in the United States over a 30 year lifetime
there is about a 1% chance of a large release due to internal events.
26. -Solar Power – uses the sun energy to either boil water or directly converts
solar energy to electrical energy
-Ocean Thermal Energy Conversion – uses temperature differences
between different depths of ocean water to drive a heat engine. Working
fluid is ammonia which is gas at room temperature.
-Biomass Energy: Municipal Solid Waste – burning wastes to drive heat
engines
-Geothermal Energy – based on naturally occurring heat in the Earth in the
Earth due to radioactive decay
-Tidal Energy – uses the gravitational pull of the moon on our oceans to
drive turbines
