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.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
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.
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.

What is an Optimization
Introduction to Peephole Optimization
Working Flow of Peephole Optimization
Replacement Rules
Functioning of Peephole Optimization & Example
Conclusion

3. What is Optimization ??
Process of transforming a piece of code to make it more efficient (eitherin
terms of time or space) without changing its output or side-effects.
Tries to minimize or maximize some attributes of an executable computer
program.
4. Introduction to Peephole
Optimization ??
Optimization performed over a very small set of
instructions in a segment of generated code.
Works by recognizing sets of instructions that can be
replaced by shorter or faster sets of instructions.
Goals:
improve performance
reduce code size
reduce memory footprint
5. Why it’s needed ??
After compilation, the code still has some flaws
Scheduling & allocation really are NP-Complete
Optimizer may not implement every needed transformation
Curing the problem
More work on scheduling and allocation
Implement more optimizations
— or —
Optimize after compilation
Peephole optimization
Link-time optimization
7. Replacement Rules
Common techniques applied in peephole optimization:-
Constant folding
– Evaluate constant sub-expressions in advance.
Strength reduction
– Replace slow operations with faster equivalents.
Null sequences
– Delete useless operations.
Combine operations
– Replace several operations with one equivalent.
Algebraic laws
– Use algebraic laws to simplify or reorder instructions.
Special case instructions
– Use instructions designed for special operand cases.
Address mode operations
– Use address modes to simplify code.
9. Functioning (Contd…)
Replacing slow instructions with faster ones
The following Java byteCode
...
load 1
load 1
mul
...
Can be replaced by
...
load 1
dup
mul
...
10. Functioning (Contd…)
Removing redundant code
Another example is to eliminate redundant load stores.
a = b + c;
d = a + e;
is straightforwardly implemented as
MOV b,
ADD c,
MOV R0, a
MOV a,
ADD e,
MOV R0, d
R0 # Copy b to the register
R0 # Add c to the register, the register is now b+c
# Copy the register to a
R0 # Copy a to the register
R0 # Add e to the register, the register is now a+e [(b+c)+e]
# Copy the register to d
11. Functioning (Contd…)
Removing redundant code
but can be optimized to
MOV b,
ADD c,
MOV R0, a
ADD e, R0
MOV R0, d
R0 # Copy b to the register
R0 # Add c to the register, which is now b+c (a)
# Copy the register to a
# Add e to the register, which is now b+c+e [(a)+e]
# Copy the register to d
12. Functioning (Contd…)
Removing redundant stack instructions

PUSH BC PUSH BC
PUSH DE PUSH DE
PUSH HL PUSH HL
POP HL POP HL
POP DE POP DE
POP BC POP BC
POP AF POP AF
CALL _ADDR1 CALL _ADDR2
PUSH AF

PUSH DE
PUSH HL

CALL_ADDR2
POP HL

13. Functioning (Contd…)
Source Code:
If ( a<b ) {
a = a + b;
}
Peephole optimization ofjumps
Eliminate jumps to jumps
Eliminate jumps after conditional branches
“Adjacent” instructions = “Adjacent in control flow”
IL Code:
PUSH a
PUSH b
CMP a,b
JUMP L1
EXIT
L1:
ADD a,b
14. Other Considerations
Control-flow operations
Can clear simplifier’s window at branch or label
More aggressive approach: combine across branches
Same considerations arise with predication
Physical versus logical windows
Can run optimizer over a logical window
Logical windows (within block) improve effectiveness
15. Conclusion
So…
Peephole optimization remains viable
Post allocation improvements
Cleans up rough edges
Peephole technology works for selection
Description driven matchers
Used in several important systems
All of this will work equally well in binary-to-binary translation
