Abstract: In multi-robot systems, accurate relative localization is indispensable for executing collaborative tasks in GPS-denied environments. This paper focuses on the relative localization problem ...

Abstract: In this letter, we present a method for minimizing the time required for a redundant dual-arm robot to follow a desired relative Cartesian path at constant path speed by optimizing its joint ...

Elderly Hongkongers and people with chronic illnesses should protect themselves from health problems arising from high humidity by using dehumidifiers and removing mould, a doctor and a community ...

So, you’re driving a car at half the speed of light. (Both hands on the wheel, please.) You turn on the headlights. How fast would you see this light traveling? What about a person standing by the ...

This paper explores the Relative Age Effect (RAE) after nearly 40 years since its initial examination in sports. Two original studies identified significant participation differences between ...

Taking regular walks may add years to your life. Studies have shown that walking improves muscular function and lowers the risk of type 2 diabetes, cancer, and cardiovascular disease. You don’t even ...

Widely accepted wisdom has it that electric vehicles are easier to maintain than those with internal combustion powertrains. It seems intuitive—EVs have many fewer moving parts than cars that have to ...

This work uncovers the mystery of ductile-to-brittle transition (DBT) in body-centered cubic (BCC) metals. Temperature-dependent dislocation mobility and dislocation nucleation have been proposed as ...

The speed of light in a vacuum is the ultimate cosmic speed limit. Just getting close to it causes problems: the weird distortions of Einstein’s relativity kick in, so time slows down, lengths go up, ...

Geoffrey A. Kerchner, assistant professor of neurology and neurological sciences at the Stanford University School of Medicine, responds: To a brain scientist, processing speed means just that: the ...
