Engineers built E-BAR, a mobile robot designed to physically support the elderly and prevent them from falling as they move around their homes. E-BAR acts as a set of robotic handlebars that follows a ...

Abstract: This paper presents an optimization approach for static antenna array thinning using a genetic algorithm (GA). The goal is to reduce hardware complexity while maintaining a radiation pattern ...

Abstract: For synthesizing ultrawideband (UWB) beam-scanning aperiodic antenna arrays under mutual coupling (MC) effects, the novel constraint-reduced iterative convex optimization (CRICO) method with ...

Israel’s recognition of Somaliland landed like a dropped plate in a room full of diplomats pretending not to hear the crash. Somalia protested. The Arab League scolded. Qatar, Turkey and Egypt warned ...
