Ocean and Wave Energy or Ocean Power ConversionTechnologiesTesfaye Birara
Energy conversion is the process of changing one form of energy into another, a fundamental capability that enables modern civilization to function. It can occur in various ways, from converting the kinetic energy of wind into mechanical power through windmills to transforming solar energy into electrical energy in solar panels. This transformation is essential not just for daily usage but also for harnessing and utilizing natural resources more efficiently. In the context of rural electrification, this process plays a critical role. By converting available local energy resources into electricity, rural communities can access a stable and reliable power supply. This not only improves the quality of life but also supports economic development by powering homes, schools, businesses, and healthcare facilities. Consequently, energy conversion facilitates the broader goal of rural electrification, demonstrating the interconnection between technological innovation and societal advancement.

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.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

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.

energy
• Waves are
generated by the
winds as it blows
across the sea
surface.
• Wave energy is
sometimes
confused with tidal
energy, which is
quite different.
• Waves travel far
distances across
oceans at great
speed.
5. History
The first known patent to use energy from ocean waves dates back to 1799
and was filed in Paris by Girard and his son.
An early application of wave power was a device constructed around 1910 .
From 1855 to 1973 there were already 340 patents filed in the UK alone.
A renewed interest in wave energy was motivated by the oil crisis in 1973.
In the 1980s, a few first-generation prototypes were tested at sea.
In 2008, the first experimental wave farm was opened in Portugal, Its
capacity is 2.25 MW.

9. Attenuator
• Attenuator lies parallel to the sea level and
rides every wave.
• That device capture energy from the relative
motion of it’s arms.
• It’s basically floating device anchored to the
seabed.
• It’s also known as pelamis.
10. Point Absorber
• A point absorber is a floating structure which
absorbs energy from all motion direction.
• It converts the motion of the buoyant top
relative to the base to electrical power.
• It’s base is a dead weight positioned at the
seabed.
• Because of it’s small size , the wave
direction isn’t important .
11. Oscillating Water Column
• (OWC) is mainly a shoreline wave energy
device onto or near to rocks or cliffs.
• It consists of a partly submerged hollow
chamber fixed at the shoreline.
• The motion of the wave into the chamber is
converted to air pressure.
• This air is compressed and decompressed by
the motion of the wave every cycle.
12. Oscillating Wave Surge Conv.
• These devices typically have one end fixed
to the seabed and the other is free.
• Energy is collected from the relative motion
of the body compared to the fixed point.
• The arm oscillates as a pendulum and the
pistons compress sea water in flow line.
• The water passes the turbine then flow back
to the sea.
13. Overtopping Device
• Overtopping devices capture water as waves
break into a storage reservoir.
• Water is then returned to the sea passing
through low-head turbine generating power.
• An over topping device may use (collectors)
to concentrate the wave energy.
• it’s basically an electric turbine.

19. Egypt
Around 3000 kilometers of sea coasts may provide Egypt
with energy resource -Wave energy- that may be used for
electricity
The main electricity generation resources in Egypt are
thermal power plants operated with petroleum fuel
and/or natural gas, and hydro-power plants located at
the river Nile
86.8% of this amount have been generated from thermal
resources, while the remaining amount have been
produced from the hydro-power plants and the wind farm
in Zaafarana on the red sea coast
20. Challenges
• Some devices already been destroyed by the forces of tides and strong storms
• Accessibility, maintenance and repair can also be costly
• The typical efficiency of a wave energy device at the moment being only about 30 % .
• There is a potential impact on the marine environment.
• Noise pollution, for example, could have negative impact if not monitored, although the noise and visible
impact of each design varies greatly
• Wave farms can result in the displacement of commercial and recreational fishermen from productive
fishing grounds
