In order to eliminate the transient process of the hydrogen energy system of the hydrogen power locomotive upon switching between the grid-connected and standalone control modes, a seamless switching control approach for the hydrogen energy and pantograph-catenary parallel power supply system was proposed in this paper.With the control power target
Motivated by the importance and application of discrete dynamical Football - Protective - Helmets systems, this paper presents a new Lyapunov characterization which is an extension of conventional Lyapunov characterization for multistable discrete-time nonlinear systems.Based on a new type stability notion of W-stability introduced by D.Efimov, the
A specimen of Champsodon vorax Günther, 1867, of 113 mm SL, was caught on 6 September 2014 with a bottom trawl from the entrance of the Bay of Izmir, north-eastern Aegean Sea at a depth of 65 m.The presently reported study constitutes the first L-CARNITINE record for the Aegean Sea but also the fourth record for the Mediterranean Sea.The s
The effects of adhesive layer on the multi-hit ballistic performance of ceramic/metal composite armors are studied by the experimental and numerical methods.The types (epoxy and polyurethane), bonding performance (bonding strength and failure displacement) and thickness, ranging from 0.2 to 3.0 mm, of adhesive layer are systematically investigated
