A queue is a first-in, first-out (FIFO) data structure where elements are inserted at the rear and deleted from the front. There are two common implementations - a linear array implementation where the front and rear indices are incremented as elements are added/removed, and a circular array implementation where the indices wrap around to avoid unused space. Queues have applications in printing, scheduling, and call centers where requests are handled in the order received.
Queue is an abstract data structure, somewhat similar to Stacks. Unlike stacks, a queue is open at both its ends. One end is always used to insert data (enqueue) and the other is used to remove data (dequeue). Queue follows First-In-First-Out methodology, i.e., the data item stored first will be accessed first.
An ordered collection of items from which items may be deleted from one end called the front and into which items may be inserted from other end called rear is known as Queue.
It is a linear data structure.
It is called the First In First Out (FIFO) list. Since in queue, the first element will be the first element out.
In computer science, a data structure is a data organization, management, and storage format that enables efficient access and modification. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data. https://apkleet.com

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

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
A Strategic Approach: GenAI in EducationPeter 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.

3. Intro
• Queue is a linear list of elements in which deletion of an element can
take place at one end, called the front and insertion can take place at
the other end, called the rear.
• The first element in a queue will be the first one to be removed from
the list.
• Queues are also called FIFO (First In First Out) i.e. the data
item stored first will be accessed first
3
5. Applications of queue
• Serving requests on a single shared resource, like a printer, CPU task
scheduling etc.
• In real life, Call Center phone systems will use Queues, to hold
people calling them in an order, until a service representative is free.
• Handling of interrupts in real-time systems. The interrupts are
handled in the same order as they arrive, First come first served.
5
6. The queue as an ADT
• A queue q of type T is a finite sequence of elements with the
operations
• MakeEmpty(q): To make q as an empty queue
• IsEmpty(q): To check whether the queue q is empty. Return true if q is
empty, return false otherwise.
• IsFull(q): To check whether the queue q is full. Return true in q is full,
return false otherwise.
• Enqueue(q, x): To insert an item x at the rear of the queue, if and only if
q is not full.
• Dequeue(q): To delete an item from the front of the queue q if and only if
q is not empty.
• Traverse (q): To read entire queue that is display the content of the queue.
6
7. Enqueue Operation
• Queue maintains two data pointers, front and rear
• The following steps should be taken to enqueue(insert) data into
queue –
• Step 1 – Check if queue is full
• Step 2 – if queue is full
produce overflow error and exit
else
increment rear pointer to point next empty space
and add data element to the queue location, where rear is
pointing
• Step 3 - return success
7
10. Dequeue Operation
• Accessing data from queue is a process of two steps
• Access the data from where front is pointing
• And remove the data after access
• The following steps are taken to perform dequeue operation
• Step 1 – Check if queue is empty
• Step 2 – if queue is empty
produce underflow error and exit
else
access data where front is pointing, increment front pointer
to point next available data element
• Step 3 – return success.
10
12. Implementation of dequeue()
int dequeue() {
if(isempty()) {
return 0;
}
int data = queue[front];
front = front + 1;
return data;
}
12
13. Implementation of queue
• There are two techniques for implementing the queue:
• Array implementation of queue (static memory allocation)
• Linear array implementation (Linear Queue)
• Circular array Implementation (Circular queue)
• Linked list implementation of queue (dynamic memory allocation)
13
14. Array implementation of queue
• The easies way of implementing a queue is by using an Array.
• Initially head(FRONT) and the tail(REAR) of the queue points at the
first index of the array.
• As we add elements to the queue, we can either move tail before
adding another item or we can move the tail after adding the item,
while the head remains at the first index.
14
16. Linear Queue
Insertion of an item in queue Deletion of an item from queue
1. Initialize front=0 and rear=-1
if rear>=MAXSIZE-1
print “queue overflow” and return
else
set rear=rear+1
queue[rear]=item
2. end
1. if rear<front
print “queue is empty” and return
else
item=queue[front++]
2. end
16
17. Problems with Linear queue implementation
• Both rear and front indices are increased but never decreased.
• As items are removed from the queue, the storage space at the
beginning of the array is discarded and never used again.
• Wastage of the space is the main problem with linear queue which is
illustrated by the following example.
17
18. Circular queue
• A queue where the start and end of the queue are joined together.
• A circular queue is one in which the insertion of a new element is
done at very first location of the queue if the last location of the queue
is full.
18
20. Circular queue
isFull() IsEmpty
- If HEAD == (Tail % MAX) + 1
Then Full <- True;
Else Full <- False;
- If they have caught up to each other, then it’s full
- If Head ==Tail
Then Full <- True;
Else Full <- False;
