The Leeuwin Current (LC) is an eastern boundary current flowing strongly southwards along the Western Australian coastline. The current varies seasonally, with weaker southwards flow occurring during the austral summer (November to March), when southerly winds are strongest. Nearly 9.5 years of TOPEX/Poseidon-derived sea-surface heights, in conjunction with the AUSGeoid98 gravimetric geoid mode...

The results of low-frequency oscillations identification in the Republic Kazakhstan power grid by using a Wide Area Measurement System are presented and an algorithm for damping is proposed this paper. Analysis weakly damped inter-area revealed constant mode with frequency range 0.3‒0.4 Hz. It was determined that at these oscillations, amplitude active fluctuations along transmission line 150 M...

a portable and light pneumatic branch shake system was designed and manufactured in this research for harvesting fruits that can be harvested by shaking branch. required air flow and electric current are provided for operating system from category containing electrical generator and air compressor on wheelbarrows and portable chassis. vibration is equipped by programmable logic controller (plc)...

Considering the sequential clearing of energy and reserves in Europe, enabling inter-area reserve exchange requires optimally allocating transmission capacities between these two markets. To achieve this, we provide a market-based allocation framework derive payments with desirable properties. The proposed min-max least core selecting individual rationality, budget balance, approximate incentiv...

By use of the multi-Josephson junction model, we investigate voltage-biased I-V characteristics. Differently from the case of the single junction, I-V characteristics show a complicated behavior due to inter-layer couplings among superconducting phase differences mediated by the charging effect. We show that there exist three characteristic regions, which are identified by jumps and cusps in th...
