There are four main types of polarization that can occur in dielectric materials when an electric field is applied: 1) Electronic polarization, which is caused by the shifting of electron clouds relative to atomic nuclei. 2) Ionic polarization, which is the shifting of ionic charges in ionic compounds. 3) Orientational polarization, which is the alignment of permanent molecular dipoles along the field. 4) Space charge polarization, which is the separation of electric charges in the material. The total polarization of a dielectric is the sum of these individual polarization contributions.
Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance. This capacity produces interesting and potentially useful effects. For a material to behave as a superconductor, low temperatures are required.

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.

2. WHAT IS DIELECTRIC POLARIZATION
When an electric field is applied across a dielectric material then
the dielectric material becomes polarized . This mechanism is
called dielectric polarization.
3. TYPES OF POLARIZATION
There are four types of polarization
1. Electronic polarization
2. Ionic polarization
3. Orientational polarization
4. Space charge polarization
16. Orientational Polarization
When an electric field is applied on an dielectric material with
permanent dipole moment (μ), the applied field tries to orient the
dipole along its direction . The orientational polarization is given by
αo is orientation polarizability
17. • Thus the orientational polarizability is a temperature dependent term
and is inversely proportional to the absolute temperature of the
dielectric material.
• It is slow process compare to ionic and electronic polarization.
• All the molecular dipoles are oriented randomly when there is no
Electric field.
• In the presence of the electric field these dipoles orient themselves in
the direction of field as a result the net dipole moment becomes
enormous.
18. Space charge polarization
• When an electric field is applied to a bulk dielectric material the
charges in the material diffuse to a considerable distance with
response to the applied field .
• This is very slow process and contribution to the total polarization
from space charge polarization is neglizible .
19. Total Polarization
• Total Polarization is the sum of polarizations due to electronic ,ionic,
orientational and space charge polarizabilities.
