Sustainable artificial intelligence: from ChatGPT to green AI

A decade ago, Luís Cruz worked on developing software tools to bring artificial intelligence (AI) to smartphones. It quickly triggered the question of energy efficiency. Not with the noble goal of making them more sustainable but to prevent them from draining the battery too quickly. Cruz went searching for tools and knowledge, but encountered an empty field. “It made me realize there was a need for research,” he says. Soon thereafter he started his PhD research project on ‘green software’, starting simple by studying the energy efficiency of basic mobile apps. As an assistant professor at TU Delft, Cruz remains passionate about sustainable software, specifically AI.

'Elderly' first Dutch nanosatellite celebrates fifteenth birthday

She is affectionately referred to as "the old lady". After 15 years in space, she can safely be called very elderly. Few of her peers are still operational at her age. But the old lady is also hard of hearing and barely understandable. This month, the self-proclaimed adventurers who built her, celebrate her birthday but fear it will be her last. Proud father of the very first hour Chris Verhoeven (Faculty of EEMCS) and current caretaker Stefano Speretta (Faculty of AE) describe the Delft nanosatellite Delfi-C3 that exceeded all expectations.

Supercomputing power for racing cars and quantum states

A remarkable service on the TU Delft campus: a supercomputer for anyone in need supercomputing power. DelftBlue, as the new supercomputer is called, has now been in use for over a year. Researchers and students make full use of the 1.05 petaflops, 10,000 CPU cores and more than 200 computing nodes – a doubling in size is already planned. From fundamental quantum research to designing electric racing cars, what are their experiences like?al and the human factor. The goal: simply better software.

A bit of math to constrain epidemics

Most people like to keep both mathematics and epidemics at a distance. But a little bit of the former can do wonders in limiting the latter. Supervised by professor Kees Vuik, two high school students modelled a recent outbreak of cholera in Ghana. He also has a bachelor student investigating the new corona virus.

A safe and just algorithm? Start with a systems perspective

Whereas algorithms are good at keeping planes airborne and forthcoming self-driving cars on the road, algorithmic decision-making by the government puts civilians at ever-increasing risk. Unless we apply lessons from systems and control engineering to the design processes and governance of public algorithmic systems, like Roel Dobbe does.

Discoveries and research in the treasuries of architecture

You might not even notice when visiting the Nieuwe Instituut in Rotterdam, but the north side of this museum is completely enclosed by a curved structure on stilts. This so-called 'banana' contains our national architectural collection: a compilation of archives, some dating back to the 19th century, which together form one of the largest architectural archives in the world.
