Induction motors are widely used worldwide for domestic and industrial applications. Fault detection classification techniques based on signal analysis have increased in popularity due to the growing use of induction new technologies such as electric vehicles, automatic control, maintenance systems, inclusion renewable energy sources electrical among others. Hence, monitoring, fault detection, ...

We show how to apply the Leggett-Garg inequality to opto-electro-mechanical systems near their quantum ground state. We find that by using a dichotomic quantum nondemolition measurement (via, e.g., an additional circuit-QED measurement device), either on the cavity or on the nano-mechanical system itself, the Leggett-Garg inequality is violated. We argue that only measurements on the mechanical...

One of the most precise and reliable measurement methods for density measurement of liquids and gases depends on the principles of a mechanical oscillator. With this method the density is determined by measuring the natural frequency of the oscillator. Measurement devices using this method can be categorized in two groups. The first type incorporates the mechanical oscillator in the housing of ...

In many applications of regression discontinuity designs, the running variable used to assign treatment is only observed with error. We show that, provided (i) correctly classifies assignment and (ii) affects conditional means potential outcomes smoothly, ignoring measurement error nonetheless yields an estimate a causal interpretation: average effect for units whose equals cutoff. Possibly aft...

Continuous-variable measurement-device-independent quantum key distribution (CV-MDI-QKD) allows remote parties to share information-theoretical secure keys while defending all the side-channel attacks on measurement devices. However, transmission distance and secret rate are quite limited due high untrusted equivalent excess noise in Gaussian modulation. More particularly, extremely high-effici...
