We propose a qubit-qubit coupling scheme for superconducting flux quantum bits (qubits), where a quantized Josephson junction resonator and microwave irradiation are utilized. The junction is used as a tunable inductance controlled by changing the bias current flowing through the junction, and thus the circuit works as a tunable resonator. This enables us to make any qubits interact with the re...

Thermal pretreatments of rock, such as conventional heating and microwave irradiation, have received considerable attention recently a viable method improving the energy efficiency mining processes that involve rock fracturing. This study presents numerical analysis effects thermal shock on mechanical properties hard, granite-like rock. More specifically, aim is to numerically assess reduction ...

Climate model experiments are analyzed to elucidate if and how the changes in mean climate in response to doubling of atmospheric CO2 (2xCO2) influence ENSO. The processes involved the development, transition, and decay of simulated ENSO events are quantified through a multimodel heat budget analysis. The simulated changes in ENSO amplitude in response to 2xCO2 are directly related to changes i...

Moisture flux and rainfall anomalies over southern Africa that have occurred during strong warm SST events off the coast of Angola since 1950 are considered. These events typically occur during February-April (FMA), the main rainy season for Angola/northern Namibia. Eleven of these events have occurred in this 60 year period and each experiences increased rainfall somewhere in coastal Angola, a...

An interior permanent magnet synchronous motor (IPMSM) drive system with machine learning-based maximum torque per ampere (MTPA) as well flux-weakening (FW) control was developed and is presented in this study. Since the performance of IPMSM varies significantly due to temperature variation magnetic saturation, a MTPA using Petri probabilistic fuzzy neural network an asymmetric membership funct...

Dual permanent magnet (PM) machines have attracted numerous interests due to the high torque density and compact volume . This article investigates a synergistic PM with synergies of flux switching reversal effects. The flux-reversal flux-switching (FSPM) paths circulate from two sides split te...

This paper presents a strategy for permanent magnet synchronous motor sensorless vector control based on rotor flux estimation considering saliency. The integration problem in the stator was solved by replacing integrator with low-pass filter. filter parametric adaptation algorithm phase delay compensation, Bode diagrams designed angular position accuracy improving. proposed adaption allowed to...
