This document presents elements of publicity for a specific category of goods, namely, ships.It also analyzes the recording and registration of Romanian flag ships.Each of these items requires special procedures, depending on the operation recorded where the ship is registered.The registration of ships under construction and especially of Romanian

This paper deals with a novel natural sampled pulse width modulation (PWM) switching strategy for voltage source inverter through copyright modification.The proposed inverted sine copyright PWM (ISCPWM) method, which uses the conventional sinusoidal reference signal and an inverted sine copyright, has a better spectral quality and a higher fundamen

We present a proof-of-principle study about the use of a sensor for the nondestructive monitoring of strength development in hydrating concrete.The nondestructive evaluation technique is based on the propagation of highly nonlinear solitary waves (HNSWs), which are non-dispersive mechanical waves that can form and travel in highly nonlinear systems

Traditional sensor nodes are usually battery powered, and the limited battery power constrains the overall lifespan of the sensors.Recently, wireless power transmission technology has been applied in wireless sensor networks (WSNs) to transmit wireless power from the chargers to the sensor nodes and solve the limited battery power problem.The combi
