We're working with many partners in the #hySUCCESS consortium to look at the social and economic impact of green #hydrogen and the changes that need to be made to move towards a hydrogen-based economy. The consortium has been given 12 million euros from NWO (Nederlandse Organisatie voor Wetenschappelijk Onderzoek) to carry out this research 🎉. As one of the main participants CWI will look at markets and business models. "We want to develop new models for automated hydrogen-electricity markets”, senior researcher Valentin Robu explains. “For example, hydrogen can be an important source of flexibility and storage, and can relieve network #congestion, which is a major problem for the power grid in the Netherlands at the moment.” Other partners in this project are, among others: Rijksuniversiteit Groningen, Universiteit Utrecht (Utrecht University), HAN University of Applied Sciences, TU Delft, Hanzehogeschool Groningen, Universiteit Leiden and Tilburg University.   👉 https://bit.ly/3Sb9zNy

Whether they are retail chains, banks, web shops or hospitals, they all collect data and want to get as many insights from it as possible. After gathering the data, it is brought together, filtered, cleaned, aggregated and then analyzed using dashboards, statistical tools or machine learning. Databases are pivotal in this data pipeline. The latest CWI result in database architectures is the invention of so-called embedded analytics, designed to work within running processes, without the need of a separate server. A number of prior scientific inventions made at CWI have been crucial in this: 𝙘𝙤𝙡𝙪𝙢𝙣 𝙨𝙩𝙤𝙧𝙚𝙨, 𝙫𝙚𝙘𝙩𝙤𝙧𝙞𝙯𝙚𝙙 𝙦𝙪𝙚𝙧𝙮 𝙚𝙭𝙚𝙘𝙪𝙩𝙞𝙤𝙣 and 𝙛𝙖𝙨𝙩 𝙙𝙖𝙩𝙖 𝙘𝙤𝙢𝙥𝙧𝙚𝙨𝙨𝙞𝙤𝙣 𝙢𝙚𝙩𝙝𝙤𝙙𝙨.

Many AI applications can become much more 𝗲𝗻𝗲𝗿𝗴𝘆-𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 thanks to algorithmic breakthroughs in training 𝘀𝗽𝗶𝗸𝗶𝗻𝗴 𝗻𝗲𝘂𝗿𝗮𝗹 𝗻𝗲𝘁𝘄𝗼𝗿𝗸𝘀. An important development, because AI has a huge carbon footprint. Training a large AI model such as #ChatGPT has a CO2 emission equal to the emission of 60 people in the Western world! Over the past few years, senior researcher Sander Bohté and his CWI colleagues have contributed to the algorithmic breakthroughs that are finally making neuromorphic computing practical.

There is a vulnerability found in the RADIUS/UDP protocol, which is widely used for access control to networks (like Wi-Fi and VPN networks) and to network equipment (such as routers and switches).   An international team of researchers, including CWI cryptanalyst Marc Stevens, announced this today, on 9 July 2024. They named the vulnerability ‘Blast-RADIUS’.   RADIUS network traffic is typically transported unsecured via the so-called UDP network layer, protected only by cryptography based on the outdated MD5 standard.   Marc Stevens says: “We recommend the use of RADIUS/TLS, as TLS can provide strong privacy and security guarantees. Vendors and network administrators should change this.”   The researchers are, in alphabetical order: Sharon Goldberg (Cloudflare), Miro Haller (UC San Diego), Nadia Heninger (UC San Diego), Mike Milano (BastionZero (acquired by Cloudflare)), Dan Shumow (Microsoft Research), Marc Stevens (Cryptology group of Centrum Wiskunde & Informatica) and Adam Suhl (UC San Diego).   More information and links: https://lnkd.in/eW35fvQC

In emergencies, such as cardiac arrest 🚑 or a fire, volunteers sometimes arrive faster on scene than professional first responders. CWI researcher Rob van der Mei is investigating how to optimally deploy volunteers in emergency situations. How many volunteers do you need and where do you need them the most? Rob works with Caroline Jagtenberg from Vrije Universiteit Amsterdam and Pieter van den Berg from Erasmus Universiteit Rotterdam. They received a €500,000 grant from TKI DINALOG. In an earlier study that lead to this cooperation, Rob worked together with Brandweer Amsterdam-Amstelland, which has the ambitious plan to recruit 100,000 volunteers. This could cut the response time in an emergency 🚒 - eight minutes on average -🚒 by four minutes(!), Rob calculated. With half the number of volunteers the response time still drops with three minutes and 26 seconds ⏱. 𝗥𝗲𝗮𝗱 𝘁𝗵𝗲 𝗳𝘂𝗹𝗹 𝘀𝘁𝗼𝗿𝘆 𝗵𝗲𝗿𝗲 👉 https://bit.ly/4clL0FE

𝐔𝐧𝐥𝐨𝐜𝐤𝐢𝐧𝐠 𝐭𝐡𝐞 𝐦𝐲𝐬𝐭𝐞𝐫𝐢𝐞𝐬 𝐨𝐟 𝐭𝐡𝐞 𝐒𝐢𝐦𝐩𝐥𝐞𝐱-𝐚𝐥𝐠𝐨𝐫𝐢𝐭𝐡𝐦 The most popular optimization method is an #algorithm, developed in 1947. Why is it still so successful? CWI researchers were able to shed some light on the matter. Despite decades of explosive growth in computing power, it is still this 1947 Simplex-algorithm that is the most successful for optimizing logistical problems. It is widely applied in areas ranging from manufacturing and transport to telecommunication. And the mystery is that no one can put their finger on theoretical reasons why this algorithm is so successful in practice. But over the past few years, CWI researchers have been able to shed some light on the matter, building on earlier work of American mathematicians. CWI researcher Daniel Dadush, leader of the Networks & Optimization group at CWI and professor at Utrecht University, realized that trying to shed some light on the mysteries of the Simplex algorithm was high risk, high gain research. But together with Sophie Huiberts, who worked first as a master student and later as a PhD student, he decided to take the risk, in the spirit of CWI’s long term mission. 🔗 Read more about how they put the puzzle together in the story on our website: https://lnkd.in/eesCT3Q6
