Adaptive Huffman coding is an improvement over standard Huffman coding that allows the Huffman tree to be adapted as additional symbols are encoded. It determines codeword mappings using a running estimate of symbol probabilities. This allows it to better exploit locality in the data. The algorithm works in two phases: first, it transforms the existing Huffman tree to maintain optimality when a symbol's weight is incremented; second, it increments the weight. This process is repeated as each new symbol is encoded.

Using Transcendental Number to Encrypt BlackBerry VideoJun Steed Huang
The basic concept of motion image based wireless monitoring and control system, the main requirements from the M2M communities and related encryption method of the wireless system are described. There are four different ways to explain what is M2M video streaming solutions: Machine2Man (for security applications), Man2Man (for commercial fast delivery services), Man2Machine (for mining and oil industries) and Machine2Machine (for environmental protections). The scrambling of motion image based video signals is done by using transcendental number that is iterated over Fibonacci prime number sequence, with video time stamp and user pass phrase, the simulation and experiment are reported. The major challenge in this area is providing low computation algorithm that runs easily on embedded Java application, without compromising a hack-proof security feature.

FPGA Implementation of LDPC Encoder for Terrestrial TelevisionAI Publications
The increasing data rates in digital television networks increase the demands on data capacity of the current transmission channels. Through new standards, the capacity of existing channels is increased with new methods of error correction coding and modulation. In this work, Low Density Parity Check (LDPC) codes are implemented for their error correcting capability. LDPC is a linear error correcting code. These linear error correcting codes are used for transmitting a message over a noisy transmission channel. LDPC codes are finding increasing use in applications requiring reliable and highly efficient information transfer over noisy channels. These codes are capable of performing near to Shannon limit performance and have low decoding complexity. LDPC uses parity check matrix for its encoding and decoding purpose. The main advantage of the parity check matrix is that it helps in detecting and correcting errors which is a very important advantage against noisy channels. This work presents the design and implementation of a LDPC encoder for transmission of digital terrestrial television according to the Chinese DTMB standard. The system is written in Verilog and is implemented on FPGA. The whole work is then verified with the help of Matlab modelling.

Multiple Valued Logic for Synthesis and Simulation of Digital CircuitsIJERA Editor
The Multiple valued logic(MVL) has increased attention in the last decades because of the possibility to represent the information with more than two discrete levels.Advancing from two-valued to four-valued logic provides a progressive approach. In new technologies, the most delay and power occurs in the connections between gates. When designing a function using MVL, we need fewer gates,which implies less number of connections, then less delay. In the existing system, the 4:1 multiplexer is designed using the MVL logic and various paramaters are analysed. In the proposed system, the idea of designing a Barrel shifter using the multiple valued logic and the parameters are all analyzed. All these designs are verified using Modelsim simulator.
What are the most promising projects and how good are they?
In recent years different groups have used the transformer architecture (a deep learning model) to train neural networks using large quantities of text. With the increase in compute power these models have grown to billions or even hundred of billions of parameters. As the model size grew, noteworthy abilities emerged. Such as the ability to generate text showing surprising reasoning skills to the point that the leading models can now successfully take college-level exams.
Currently some of the best and most famous models are proprietary and released to the public as a service. However a large Open Source community has emerged that tries to train and fine tune free models that can be used self-hosted. This is a challenging task due to problems with potential copyright issues with the training text, the large computational cost of the training itself and the supervised fine tuning step to adapt the model to its final use case.
In this talk I will give an overview on what the most promising projects in this space are and how they compare to the proprietary state-of-the-art models of the large players.

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.

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
Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
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.

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.
