The document discusses fuzzy logic and its applications in machine learning. It explains that fuzzy logic can handle imprecise or uncertain data using intermediate truth values between 0 and 1, rather than binary true/false values. It describes the key components of a fuzzy logic system: the rule base, fuzzification, inference engine, and defuzzification. The advantages are its ability to handle noisy or distorted data, its simple construction, and its resemblance to human reasoning. Applications include altitude control of spacecraft, automotive speed control, and traffic control.
In order to check performance of Fuzzy APC vs. WA APC simulation of the system performed (Labview).
Dose values were taken as input variables, also Focus values are present, but not used in simulation.
Membership function were created as well as for Dose and Focus variables.
Rules includes Dose and Focus impact, but feedback loop updates just Dose performance (close simulation for FAB Litho tool activity).
Actual simulation not included any translation of Dose values to CD values for given Focus, it assumes that any inconsistencies are added as WN or trend in the final measurement.
WA APC simulated as 5 tag window with 0.35/0.25/0.2/0.14/0.06 weights accordingly which is effectively matched NSO exponential weights average approach.

Soft Computing is the fusion of methodologies that were designed to model and enable
solutions to real world problems, which are not modeled or too difficult to model, mathematically. Soft
computing is a consortium of methodologies that works synergistically and provides, in one form or
another, flexible information processing capability for handling real-life ambiguous situations. Its aim is to
exploit the tolerance for imprecision, uncertainty, approximate reasoning and partial truth in order to
achieve tractability, robustness and low-cost solutions. The guiding principle is to devise methods of
computation that lead to an acceptable solution at low cost, by seeking for an approximate solution to an
imprecisely or precisely formulated problem.Soft Computing (SC) represents a significant paradigm shift
in the aims of computing, which reflects the fact that the human mind, unlike present day computers,
possesses a remarkable ability to store and process information which is pervasively imprecise, uncertain
and lacking in categoricity. At this juncture, the principal constituents of Soft Computing (SC) are: Fuzzy
Systems (FS), including Fuzzy Logic (FL); Evolutionary Computation (EC), including Genetic
Algorithms (GA); Neural Networks (NN), including Neural Computing (NC); Machine Learning (ML);
and Probabilistic Reasoning (PR). In this paper we focus on fuzzy methodologies and fuzzy systems, as
they bring basic ideas to other SC methodologies
Logika Fuzzy merupakan suatu logika yang memiliki nilai kekaburan atau kesamaran (fuzzyness) antara benar atau salah. Dalam logika klasik dinyatakan bahwa segala hal dapat
diekspresikan dalam istilah binary (0 atau 1, hitam atau putih, ya atau tidak), sedangkan logika fuzzy memungkinkan nilai keanggotaan antara 0 dan 1, tingkat keabuan dan juga hitam dan putih, dan dalam bentuk linguistik, konsep tidak pasti seperti "sedikit", "lumayan" dan "sangat". Logika ini berhubungan dengan himpunan fuzzy dan teori kemungkinan. Logika fuzzy ini diperkenalkan oleh Dr. Lotfi Zadeh dari Universitas California, Berkeley pada 1965. Logika fuzzy dapat digunakan dalam bidang teori kontrol, teori keputusan, dan beberapa bagian dalam managemen sains. Selain itu, kelebihan dari logika fuzzy adalah kemampuan dalam proses penalaran secara bahasa (linguistic reasoning), sehingga dalam perancangannya tidak memerlukan persamaan matematik dari objek yang dikendalikan.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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

Aim: Machine Learning with Fuzzy Logic(features selection)
Theory:
❖ The term fuzzy refers to things that are not clear or are vague.
❖ In the real world many times we encounter a situation when we can’t determine whether the state
is true or false, their fuzzy logic provides very valuable flexibility for reasoning. In this way, we can
consider the inaccuracies and uncertainties of any situation.
❖ In the boolean system truth value, 1.0 represents the absolute truth value and 0.0 represents the
absolute false value. But in the fuzzy system, there is no logic for the absolute truth and absolute
false value. But in fuzzy logic, there is an intermediate value too present which is partially true and
partially false.
2. Its Architecture contains four parts :
RULE BASE: It contains the set of rules and the IF-THEN conditions provided by the experts to govern the
decision-making system, on the basis of linguistic information
FUZZIFICATION: It is used to convert inputs i.e. crisp numbers into fuzzy sets. Crisp inputs are basically the exact
inputs measured by sensors and passed into the control system for processing, such as temperature, pressure,
rpm’s, etc.
INFERENCE ENGINE: It determines the matching degree of the current fuzzy input with respect to each rule and
decides which rules are to be fired according to the input field. Next, the fired rules are combined to form the
control actions.
DEFUZZIFICATION: It is used to convert the fuzzy sets obtained by the inference engine into a crisp value. There
are several defuzzification methods available and the best-suited one is used with a specific expert system to
reduce the error.
3. Advantages of Fuzzy Logic System :
• This system can work with any type of inputs whether it is imprecise, distorted or noisy input
information.
• The construction of Fuzzy Logic Systems is easy and understandable.
• Fuzzy logic comes with mathematical concepts of set theory and the reasoning of that is quite simple.
• It provides a very efficient solution to complex problems in all fields of life as it resembles human
reasoning and decision-making.
• The algorithms can be described with little data, so little memory is required.
Disadvantages of Fuzzy Logic Systems
• Many researchers proposed different ways to solve a given problem through fuzzy logic which leads to
ambiguity. There is no systematic approach to solve a given problem through fuzzy logic.
• Proof of its characteristics is difficult or impossible in most cases because every time we do not get a
mathematical description of our approach.
• As fuzzy logic works on precise as well as imprecise data so most of the time accuracy is compromised.
Application
• It is used in the aerospace field for altitude control of spacecraft and satellites.
• It has been used in the automotive system for speed control, traffic control.
