Jitter is a very important topic in signal integrity for high speed serial data links. The jitter performance of clock signals used in generating the serial data signal is critical to the overall performance of these signals.
Phase noise is the most sensitive and accurate measurement of the performance of precision clocks.
This presentation covers the theory and practice for making phase noise measurements on clock signals as well as the relationship between phase noise and total jitter, random jitter and deterministic jitter. Measurements on a typical clock signal is also included.

Low-cost microcontrollers are being used more and more often in embedded applications that previously may have used a microprocessor. Microcontrollers often run a real-time operating system (RTOS) rather than a full operating system like Linux. In this webinar we introduce FreeRTOS, a popular RTOS for microcontrollers that has been ported to 35 microcontroller platforms.
Human–robot interaction is the study of interactions between humans and robots. It is often referred as HRI by researchers. Human–robot interaction is a multidisciplinary field with contributions from human–computer interaction, artificial intelligence, robotics, natural language understanding, design, and social sciences.
This presentation gives an overview of the PIC micro-controllers. Additionally, it describes the advantages, disadvantages and applications of these micro-controllers. It also explains real-world projects that are possible using the PIC micro-controllers.

Creating the Competitive Edge: Successfully establish, lead and mentor a stud...Conny Liegl
As a student supervisor of a team of six at Kennedy Library, I am challenged not just with providing services to clients and stakeholders, but also carry a moral responsibility for my employed students. Students are essential to my daily work, and indispensable for many large-scale, high-visibility projects. It is important to identify individual students’ needs and goals, as well to recognize current stressors and worries. It is essential to me to provide student assistants with valuable experiences that directly apply to their interests and their future job tasks. To mentor effectively also means to collaborate broadly with colleagues from different disciplines and colleges in hands-on partnerships. Class assignments, senior projects and staff collaborations provide opportunities for students to experiment, explore and broaden students’ skillsets.
With a team of web developers, graphic designers and user experience student assistants, we managed to convince stakeholders of a mobile-first approach for our website, and encourage students to combine senior projects with their assistantship.
My ten rules for an effective student-supervisor relationship, which I will elaborate in my presentation, are: 1. Give pointers and directions, not orders. 2. Teach only what you’re good at. 3. Take students seriously. 4. Talk and sketch together. 5. Listen. 6. Watch. 7. Learn. 8. Experiment. 9. Keep problems away. 10. Have fun! To prove the effectiveness of these simple rules, I will highlight library projects, faculty collaborations and successful partnerships with examples from Outstanding Student Employees of the Year, Hackathon competitors and successful graduates.
This presentation material is my review about SOTA model related paper entitled with "Code Translation with Compiler Representations". It is a paper from Meta AI, and was accepted for an ICLR 2023.
Close encounters in MDD: when Models meet Codelbergmans
Model-Driven Development (MDD) promises a number of advantages, which include the ability to work at higher abstraction levels, static reasoning about models, and generation of platform-specific code. To achieve this, generally a transformation-based approach is adopted, which generates code from models. In this presentation we discuss –in addition to the potential advantages– a number of possible misunderstandings and risks of MDD.
In particular, we address the risks of transformation-based software development, such as:
• It is rarely possible to generate the full functionality of a (sub-)system from models; as a result, it is necessary to either do additional ‘manual coding’ –a challenge to integrate with the generated code– or annotate the model with small or larger fragments of executable code, which has several restrictions and practical consequences: for instance it mingles abstraction levels, and reduces maintainability of code and models.
• MDD is particularly effective when various different models can be used, each optimized for a specific domain. However, when using transformation techniques, de combination of multiple models in an integrated application is far from trivial.
In this talk we propose –as a low-threshold approach–, ‘bottom-up’ model-driven development. This means that the focus on domain-specific abstractions remains, as well as the separation of platform-specific and platform-independent software. This approach, which is related to Domain-Driven Design and domain-specific languages (DSLs), aims to exploit the advantages of modeling in terms of abstractions, while at the same time reducing the gap between models and code. This can be achieved by specifying the models in code, while separating platform-specific code from the model code. An important issue is the capability to combine several different models, without getting into technical difficulties: we discuss existing as well as a novel approach, entitled Co-op, which aim to address this problem.

Helidon Nima - Loom based microserfice framework.pptxDmitry Kornilov
For quite a long time we were forced to make a choice - performance vs. simplicity. Either use a complicated and performant reactive code, or use simple, yet limited blocking approach.Thanks to project Loom in JDK, the paradigm can shift once more even for applications that require high concurrency. I will introduce Helidon Nima - new microservices framework which is built on top of a server designed for Loom with fully synchronous routing that can block as needed, yet still provide high performance under heavy concurrent load. I'll also talk about challenges, benefits and impact on application development in such an environment.
El paradigma Cloud Computing se centra en solucionar uno de los problemas fundamentales e históricos
que en la actualidad que se enfrentan las ITs cuando tienen que hacer uso de servicios o aplicaciones en
Internet: La necesidad de incrementar la capacidad de usuarios manteniendo la calidad en el servicio,
mejorar la disponibilidad o añadir funcionalidades al vuelo en sus servicios en Internet sin tener que realizar
una inversión y planificación en una nueva infraestructura, entrenar a nuevo personal o cambiar el software
existente en toda la infraestructura.
El presente trabajo pretende abordar la explicación de los conceptos básicos de lo que se conoce como
Cloud Computing, pero sobre todo pretende analizar y detallar como está siendo abordado dicho paradigma
por Amazon centrándose en el servicio conocido como Amazon Elastic Cloud Computing (Amazon EC2).
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
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.
