2 QuantumConnect: Particle Collision Challenge

Step into the world of quantum coding with QuantumConnect, where you will craft your own Java programs to compete in a Connect 4-style game tournament. Like quantum particles racing through a collider, your program will need to react swiftly and precisely to outmaneuver opponents. Participants will have 45 minutes to create and submit their solutions, which will then go head-to-head in strategic battles, testing their adaptability and strategy.

In this fast-paced, quantum-inspired competition, outcomes will be as unpredictable as particle behavior at the quantum level. Competitors must rely on logic, quick thinking, and efficient coding to claim the title of QuantumConnect Champion. Join us for a session of intense collisions and high-energy gameplay, where coding and quantum mechanics collide in the ultimate challenge!

Speakers: Dr Cristian Schuszter (CERN), Victor Uria Valle

3 AlphaZero, Rust, and the Art of Chess Programming: Part 1

How can artificial intelligence master chess, and what can we learn from it as engineers? In this two-part presentation series, we dive into the inner workings of Google DeepMind’s AlphaZero algorithm and its groundbreaking approach to playing chess through self-learning and deep reinforcement learning. Along the way, we shift our focus from theory to practice by demonstrating how to implement a high-performance chess move generator in the Rust programming language.

This hands-on journey is more than just about chess. It’s a call to appreciate the power of systems-level thinking — bitwise operations, data efficiency, and smart tooling — core concepts often underemphasized in today’s Python-dominated programming education. Rust serves not only as a vehicle for safe and performant systems programming but also as a compelling alternative in contexts where control, concurrency, and correctness truly matter.

Whether you’re passionate about AI — not only in the context of large language models or generative pre-trained transformers — intrigued by how chess engines work, or curious about using the right tool for the job, this talk aims to inspire you to explore the full spectrum of computer engineering possibilities.

4 Complex Event Processing vs. Stream Processing

Event Pattern Matching (EPM) in real-time complex data processing refers to the technique of identifying and reacting to specific sequences of events within a continuous stream of data. It is commonly used in Complex Event Processing (CEP) systems to detect meaningful patterns or anomalies that occur across different data sources and over time.

This capability is essential in scenarios where large amounts of data are being generated continuously and require immediate or near-real-time analysis to extract actionable insights. Examples include financial markets, IoT sensors, network monitoring, and fraud detection.

In this lecture will provide an introduction to technologies behind Stream Processing (SP), Batch Processing (BP) and Complex Event Processing (CEP).

6 Enhancing Performance with Parallel Computing

In today’s world of Big Data, artificial intelligence, and real-time applications, performance is more critical than ever.

This presentation delves into the fundamentals of parallel programming, focusing on optimizing performance using shared memory with multi-core CPUs and distributed memory across networked systems.
Through practical examples, we’ll demonstrate how parallelism can significantly reduce computation times and enhance overall efficiency.
We’ll explore profiling and performance analysis techniques to help you identify bottlenecks and opportunities for parallelization, leading to the introduction of tools like OpenMP and MPI to address these challenges.

A simulation, similar to Conway’s Game of Life, will highlight the real-world advantages of parallel computing, showcasing the kinds of performance gains essential in fields like machine learning, data processing, and scientific simulations.
This simulation will also set the stage for our next topic on GPU parallelism.

9 Introduction to Alarming in Industrial Controls sector

Alarming in the industrial controls sector plays a critical role in ensuring the safety, efficiency, and reliability of automated systems. This process involves monitoring key parameters of industrial equipment and processes, generating alerts when predefined thresholds are breached, and enabling timely intervention to prevent malfunctions or safety incidents. Alarming systems are designed to provide real-time notifications to operators, facilitating quick decision-making and mitigating risks. An effective alarming strategy reduces downtime, enhances process control, and maintains compliance with safety regulations, making it a cornerstone of modern industrial automation and process control systems.

This lecture will provide you a good overview about Industrial Controls strategies for alarming, based on real examples from CERN's Technical Infrastructure Operators in the CERN Controls Centre (CCC).

17 Importance of Data Collected from the Earth's Ionosphere - Part 1

This discussion aims to highlight the importance of gathering data from the ionosphere, which can provide valuable information for satellite communication and understanding the impact of solar activity on earth.

An increase in solar activity has recently resulted in some beautiful northern and southern lights! However, they can also interfere with radio transmission and navigation systems, affecting aeroplanes and satellite internet such as Starlink. Solar flares can also influence the climate and to understand that, we need to collect further information from the ionosphere. Studying this data has gotten easier and more accessible nowadays with the help of cube satellites, as they are relatively faster to develop and maintain. These cube satellites are equipped with microcontrollers on board that can filter and analyse the data received from the plasma wave receivers attached to the satellite. We will delve deeper into the design and processes involved during the seminar.

This lecture will be divided into two parts. The first session will introduce the topic, setting the foundation for understanding the key concepts. The second session will explore the practical aspects, examining real-world applications where these technologies have been implemented, along with their advantages and limitations. The seminar will conclude with an interactive discussion, providing the audience an opportunity to share insights and ask questions.

The key takeaway is highlighting the increasing benefits of cube satellites in studying not only outer space but also terrestrial problems. It provides further insight into the various uses of microcontrollers in data collection and processing, which can make studying the impacts of outer space activity on Earth more efficient and interesting.
