Single-handed sailing circumnavigation, as it was contained within the southern hemisphere; however, he made the first single-handed passage of the three great capes, and indeed the first successful single-handed passage of Cape Horn. With only three landfalls, Vito Dumas described the legs of his trip as the longest that had been made by a single-hander, and in the most ferocious oceans on the Earth. Organised single-handed yacht racing was pioneered by Britons "Blondie" Hasler and Francis Chichester, who conceived the idea of a single-handed race across the Atlantic Ocean. This was a revolutionary concept at the time, as the idea was thought
Single-input single-output system controller design dominate SISO control system theory. Bode plot, Nyquist stability criterion, Nichols plot, and root locus are the usual tools for SISO system analysis. Controllers can be designed through the polynomial design, root locus design methods to name just two of the more popular. Often SISO controllers will be PI, PID, or lead-lag. Single-input single-output system In control engineering, a single-input and single-output (SISO) system is a simple single variable control system with one input and one output. In radio it is the use of only one antenna both in the transmitter and receiver. SISO systems are typically less
