A person's intelligence limits their computer proficiency more than previously thought, say researchers
2024-09-02 15:29:25
A new study has found that intelligence, in the form of general cognitive abilities such as perception, thinking and remembering, is more important than hitherto thought at predicting a person's ability to complete common tasks with a PC. The study was published in the International Journal of Human-Computer Studies in August 2024.

Pilot plant demonstrates iron-based hydrogen storage feasibility
2024-09-02 14:20:24
Photovoltaics are set to meet over 40% of Switzerland's electricity needs by 2050. But solar power isn't always available when it's needed: there's too much of it in summer and too little in winter, when the sun shines less often and heat pumps are running at full tilt. According to the Swiss federal government's Energy Strategy, Switzerland wants to close the winter electricity gap with a combination of imports, wind and hydropower as well as alpine solar plants and gas-fired power plants.
Exploring the fundamental reasoning abilities of LLMs
2024-09-02 14:20:24
Reasoning, the process through which human beings mentally process information to draw specific conclusions or solve problems, can be divided into two main categories. The first type of reasoning, known as deductive reasoning, entails starting from a general rule or premise and then using this rule to draw conclusions about specific cases.
A quantum neural network can see optical illusions like humans do. Could it be the future of AI?
2024-09-02 14:20:21
Optical illusions, quantum mechanics and neural networks might seem to be quite unrelated topics at first glance. However, in new research published in APL Machine Learning, I have used a phenomenon called "quantum tunneling" to design a neural network that can "see" optical illusions in much the same way humans do.

Giant batteries to store wind and solar power could speed up South Africa's energy transition
2024-08-28 17:34:56
South Africa is at a pivotal moment in its energy transition: trying to decarbonize its economy (move away from coal) and make sure that everyone has access to reliable and affordable energy. Storage of renewable energy is very important for this transition. Solar and wind power are not available all the time. To keep the national grid stable, renewable energy must be stored somewhere and supplied reliably.
