2 LightValue enum Write a simple Enum named LightValue whi.pdfadvalue015
2. LightValue enum
Write a simple Enum named LightValue, which lists the phases a particular stoplight lane may be
in. These states should include GREEN, RED, and LEFT_SIGNAL (we are considering yellow to
be part of green). Each TwoWayRoad instance (defined below) will have its own LightValue, which
should correspond to the following rules:
GREEN indicates that the right and middle lanes may proceed, but the left lane cannot (for both
directions).
RED indicates that no lane may proceed (for both directions).
LEFT_SIGNAL indicates that left can proceed, but the right and middle lanes cannot (for both
directions).
Cars in a particular lane may proceed (dequeue one car per time interval) when it is their turn to
go, according to the rules above. If you still need help with Java Enum types, you can read about
them in this Java tutorial.
3. Vehicle Class
Write a fully documented class named Vehicle. This class represents a car which passes through
the intersection. Each instance must contain the serialId (the first car to arrive at the intersection is
serialId 1, the second car to arrive is serialId 2, the n'th car to arrive will have serialId >n) and the
time it arrived (stored as an int). The car must be initialized with a serialId and the time it arrived.
The serial counter is static and stores the number of vehicles that have arrived at the intersection
so far. It is the only variable that is modifiable.
The Vehicle class itself is actually immutable. This means once it has been constructed, no data
within the instance can be changed (the static serialCounter can and should be incremented on
each constructor call). From the UML diagram, note that the public constructor takes all the
member variables as arguments. Data can still be read via the getter methods.
private static int serialCounter = 0
private int serialId
private int timeArrived
public Vehicle(int initTimeArrived)
Brief:
Default Constructor. You should automatically increment the serialCounter, and set the serialId to
its new value.
Parameters:
initTimeArrived
Time the vehicle arrived at the intersection.
Preconditions:
initTimeArrived > 0.
Throws:
IllegalArgumentException
If initTimeArrived 0.
4. VehicleQueue class
Lanes in our simulator will be modelled as a Queue of Vehicles. You may implement a Queue of
vehicles however you like, and are encouraged to use any Java API class you prefer. Remember
that the VehicleQueue class must implement the following methods in order to comply with the
Queue ADT:
void enqueue(Vehicle v)
Vehicle dequeue()
int size()
boolean isEmpty()
Note: If you decide to use a Java API class to implement VehicleQueue, you must use inheritance
(extend a Java API class) to simplify the class definition.
5. TwoWayRoad Class
Write a fully documented class called TwoWayRoad that represents one of the roads in our
intersection. Each road it bi-directional, with each direction having three lanes - a left turn lane, a
middle lane, and a right turn lane. Lanes, modelled.

them in this Java tutorial.
3. Vehicle Class
Write a fully documented class named Vehicle. This class represents a car which passes through
the intersection. Each instance must contain the serialId (the first car to arrive at the intersection is
serialId 1, the second car to arrive is serialId 2, the n'th car to arrive will have serialId >n) and the
time it arrived (stored as an int). The car must be initialized with a serialId and the time it arrived.
The serial counter is static and stores the number of vehicles that have arrived at the intersection
so far. It is the only variable that is modifiable.
The Vehicle class itself is actually immutable. This means once it has been constructed, no data
within the instance can be changed (the static serialCounter can and should be incremented on
each constructor call). From the UML diagram, note that the public constructor takes all the
member variables as arguments. Data can still be read via the getter methods.
private static int serialCounter = 0
private int serialId
private int timeArrived
public Vehicle(int initTimeArrived)
Brief:
Default Constructor. You should automatically increment the serialCounter, and set the serialId to
its new value.
Parameters:
initTimeArrived
Time the vehicle arrived at the intersection.
Preconditions:
initTimeArrived > 0.
Throws:
IllegalArgumentException
If initTimeArrived 0.
4. VehicleQueue class
Lanes in our simulator will be modelled as a Queue of Vehicles. You may implement a Queue of
vehicles however you like, and are encouraged to use any Java API class you prefer. Remember
that the VehicleQueue class must implement the following methods in order to comply with the
Queue ADT:
void enqueue(Vehicle v)
Vehicle dequeue()
int size()
boolean isEmpty()
Note: If you decide to use a Java API class to implement VehicleQueue, you must use inheritance
(extend a Java API class) to simplify the class definition.
5. TwoWayRoad Class
Write a fully documented class called TwoWayRoad that represents one of the roads in our
intersection. Each road it bi-directional, with each direction having three lanes - a left turn lane, a
middle lane, and a right turn lane. Lanes, modelled.

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
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
