Probabilistic Analysis of a Desalination Plant with Major and Minor Failures ...Waqas Tariq
In many desalination plants, multi stage flash desalination process is normally used for sea water purification. The probabilistic analysis and profitability of such a complex system with standby support mechanism is of great importance to avoid huge loses. Thus, the aim of this paper is to present a probabilistic analysis of evaporators of a desalination plant with major and minor failure categories and estimating various reliability indicators. The desalination plant operates round the clock and during the normal operation; six of the seven evaporators are in operation for water production while one evaporator is always under scheduled maintenance and used as standby. The complete plant is shut down for about one month during winter season for annual maintenance. The water supply during shutdown period is maintained through ground water and storage system. Any major failure or annual maintenance brings the evaporator/plant to a complete halt and appropriate repair or maintenance is undertaken. Measures of plant effectiveness such as mean time to system failure, availability, expected busy period for maintenance, expected busy period for repair, expected busy period during shutdown & expected number of repairs are obtained by using semi-Markov processes and regenerative point techniques. Profit incurred to the system is also evaluated. Seven years real data from a desalination plant are used in this analysis.

Revisiting Projection Methods over Automatic Oct-tree MeshesAbhishek Jain
Above Research Paper can be downloaded from www.zeusnumerix.com
This research aims to use projection methods over automatic oct-tree meshes. This algorithm uses a quick and automatic method to create solver and geometry adaptive oct-tree mesh on a basic Cartesian grid. The non-body fitted type of mesh is independent of geometry topology. The method takes multiple water tight triangulated surface(s) as an input. The software then automatically creates oct-tree based Cartesian grids both outside as well as inside the geometry. The intersection of the cells with the triangles of the geometry is done using a very robust and efficient polygon clipping algorithm allowing the capture of geometry with 100% accuracy. Simulation results show promise while solving simple cases. The mesher can be potentially used for shape optimization and aerodynamic sensitivity simulations.

Automatic Target Recognition Using Recurrent Neural NetworksAbhishek Jain
Above Research Paper can be downloaded from www.zeusnumerix.com
Automatic target recognition (ATR) using recurrent neural networks (RNN) is being proposed in this work. When electromagnetic waves from radar illuminate the targets, surface currents are produced which result in scattering of incident energy. The scattered signal in the direction of radar is received as the radar signature of the target. The radar cross-section (RCS) is an important feature extracted from the radar signature that is used for target identification. The RCS values for each set of azimuth and elevation angles for a mono-static configuration serves the purpose of the dataset for the recurrent neural network (RNN)/long short-term memory (LSTM) model. The classification accuracy of 93 per cent was achieved using the RNN/LSTM model. Authors - Sumit Jana (Zeus Numerix), Prof H Shekhawat and Bharat Sehgal (IITG)

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.

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
