Half & Full Adder Adder Logic Circuit.pptxReduan Ahmad
The half adder circuit performs binary addition on two single-bit binary numbers. The SUM output is the least significant bit (LSB) of the result, while the CARRY output is the most significant bit (MSB) of the result, indicating whether there was a carry-over from the addition of the two inputs.
A full adder is a fundamental digital circuit used in the field of electronics and computer science. It is an essential component in building more complex arithmetic and logical operations.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. Who is the father of MRI ?
Raymond Vahan Damadian
(March 16, 1936 – August 3, 2022) was
an American physician, and inventor of
the first nuclear magnetic resonance
(NMR) scanning machine.
4. MRI :
● Big magnet and radio waves
take picture inside our body , no
radiation involved.
● Super clear body pictures, helps
doctors see problems with out
hunting us .
● Secret sauce of MRI , makes
detailed pictures possible .
Introduction
01
6. A superconducting magnet is the
heart and most expensive part
of an MRI scanner.
Gradient coils are used to
produce deliberate variations in
the main magnetic field
Components of MRI
Superconducting
Gradient coils
7. Components of MRI
Gradiant coils
• Red coil – Create a varying
magnetic field from left to right .
• Yellow coil – Create a varying
magnetic field from top to bottom.
• Blue coil – Create a varying Magnetic
field from head to toe.
8. Components of MRI
RF Coils
• RF coils are the “antenna” of the
MRI system
• They are simply a loop of wire
either circular or rectangular .
[Radiofrequency]
9. Start RF pulses ( Excitation – Protons jump to
higher energy state by absorbing radiation ).
Each proton is rotating
around its axis 63,000,000
rotation per second . The 63
MHz rotation is in the
frequency range called Radio
frequency.
10. Stop RF pulses (Relaxation – Protons return to their
original state emitting radiation)
11. Equation
The Larmor equation is given by:
Here,
• ω is how fast spins move (in radians
per second),
• γ is a constant for each atom type
(gyromagnetic ratio),
• B is the magnetic field strength.
ω =γB
13. Open MRI Closed MRI
Open MRI :
• High field typically 1.5 T – 3
T(Tesla)
• High Image quality
• Fast imaging
• Advance application
Closed MRI :
• Low field typically 0.2 T – 0.4 T (Tesla)
• Low image quality
• Slow imaging
• Limited application
