Novel robust-optimal controllers based on fuzzy descriptor system
The Takagi--Sugeno (T--S) fuzzy descriptor system offers a promising avenue for controlling non-linear systems but lacks optimal control strategies. Moreover, while robust control methods have been developed, they add additional complexity. To address these limitations, a team of researchers has...
The math problem that took nearly a century to solve: Secret to Ramsey numbers
Little progress had been made in solving Ramsey problems since the 1930s. Now, researchers have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed the math world for decades....
Powerful new AI can predict people's attitudes to vaccines
A powerful new tool in artificial intelligence is able to predict whether someone is willing to be vaccinated against COVID-19....
Researchers develop a new control method that optimizes autonomous ship navigation
Existing ship control systems using Model Predictive Control for Maritime Autonomous Surface Ships (MASS) do not consider the various forces acting on ships in real sea conditions. Addressing this gap, researchers developed a novel time-optimal control method, that accounts for the real wave loads...
Balancing training data and human knowledge makes AI act more like a scientist
When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training -- such as the laws of physics --could make them more efficient and more...
Method rapidly verifies that a robot will avoid collisions
A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human....
Drawings of mathematical problems predict their resolution
Solving arithmetic problems, even simple subtractions, involves mental representations whose influence remains to be clarified. Visualizing these representations would enable us to better understand our reasoning and adapt our teaching methods. A team has now analyzed drawings made by children and...
Running performance helped by mathematical research
A new mathematical model has shown, with great precision, the impact that physiological and psychological parameters have on running performance and provides tips for optimized training....
