Fundamentals of Gauss' Law
This document discusses Gauss's law and related electromagnetic theory concepts taught in a course. It provides:
1) An overview of Gauss's law, which states that the total outward electric flux through a closed surface is equal to the total charge enclosed divided by the permittivity of the medium.
2) Derivations and proofs of Gauss's law using calculus theorems like divergence theorem.
3) Applications of Gauss's law to problems involving charge distributions and electric field calculations.
4) Discussions of related concepts like Gauss's law in polarized media, current continuity equation, relaxation time, and Poisson's equation.
5) Example problems demonstrating the application of these electromagnetic theory principles.
Fundamentals of Coulomb's Law
This document discusses Coulomb's law and some key concepts in electrostatics, including:
- Coulomb's law describes the electrostatic force between two point charges, being directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
- The electric field intensity and electric flux density are introduced.
- Properties of the electric field such as it being irrotational are examined.
- The electrostatic potential is defined and its relationship to the electric field is explored.
Vector Integration
This document discusses vector calculus theorems including Stokes' theorem and the divergence theorem. Stokes' theorem relates the line integral of a vector field around a closed curve to the surface integral of the curl of the vector field over any surface bounded by the curve. The divergence theorem relates the volume integral of the divergence of a vector field over a volume to the surface integral of the vector field over the boundary surface of that volume. The document provides proofs of these theorems and examples of their applications to problems involving conservative vector fields and evaluating integrals.
Scalar and vector differentiation
This document discusses a course on electromagnetic theory taught by Arpan Deyasi. It covers topics related to vector differentiation, including the vector differential operator in Cartesian, cylindrical and spherical coordinates. It also covers differentiation of scalar functions, including calculating gradients, directional derivatives and finding normals to surfaces. Finally, it discusses differentiation of vector functions, specifically divergence, which represents the volume density of the net outward flux from a vector field.
Coordinate transformation
The document discusses various coordinate transformations between Cartesian, cylindrical, and spherical coordinate systems. It provides the transformation equations for scalar and vector variables between these coordinate systems. Examples are included to demonstrate transforming between Cartesian and cylindrical coordinates for points in both scalar and vector form. The key topics covered are the four types of coordinate transformations, the transformation equations, and examples to illustrate the transformations.
Moletronics
Molecular electronics aims to use electronic molecules as passive or active electronic components. It has advantages over silicon technology such as smaller size (1-3 nm vs 14 nm), faster time cycles (1 fs vs 1 ns), and ability to integrate more gates per square centimeter (1013 vs 108). Major challenges include difficulty experimentally verifying and directly characterizing molecular devices and fully integrating them with silicon technology. Potential applications include sensors, display devices, energy transaction devices, smart materials, and molecular-scale logic and memory devices.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdf
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

- Objective: Demonstrate how a PassRole misconfiguration can grant unauthorized access.
- Steps:
- Allow user to pass IAM role to EC2.
- Exploit misconfiguration for unauthorized access.
- Access sensitive resources.
- Exploiting IAM AssumeRole Misconfiguration with Overly Permissive Role
- An overly permissive IAM role configuration can lead to privilege escalation by creating a role with administrative privileges and allow a user to assume this role.
- Objective: Show how overly permissive IAM roles can lead to privilege escalation.
- Steps:
- Create role with administrative privileges.
- Allow user to assume the role.
- Perform administrative actions.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Blood Finder is an emergency time app where a user can search for the blood banks as
well as the registered blood donors around Mumbai. This application also provide an
opportunity for the user of this application to become a registered donor for this user have
to enroll for the donor request from the application itself. If the admin wish to make user
a registered donor, with some of the formalities with the organization it can be done.
Specialization of this application is that the user will not have to register on sign-in for
searching the blood banks and blood donors it can be just done by installing the
application to the mobile.
The purpose of making this application is to save the user’s time for searching blood of
needed blood group during the time of the emergency.
This is an android application developed in Java and XML with the connectivity of
SQLite database. This application will provide most of basic functionality required for an
emergency time application. All the details of Blood banks and Blood donors are stored
in the database i.e. SQLite.
This application allowed the user to get all the information regarding blood banks and
blood donors such as Name, Number, Address, Blood Group, rather than searching it on
the different websites and wasting the precious time. This application is effective and
user friendly.
