The article deals with the possibilities of mathematical simulation high-capacity pumping module used in emergencies, such as floods and fires. These situations can be broad varied. In order to respond these events effectively, formulation methodology followed various scenarios very helpful. Based on MČS-25-330-K produced by Sigma company, related certified for its application field, simulation...

Sucker-rod pumping system operating status fault diagnosis technology is closely related to the energy consumption, production per well and the cost of crude oil exploration. But the knowledge depiction of the expert diagnostic system is mainly based on the production rules, neural networks or object-oriented. As ontology has advantages in hierarchy and semantic relationships expressing, it is ...

This work aims to develop an accurate model of an existing Photovoltaic Pumping System (PvPS) which is composed of an Ebara Pra-0.50T Asynchronous Moto-Pump (AMP) fed by Kaneka GSA-60 photovoltaic panels via a Moeller DV-51 speed drive. The developed model is then used to compare the performance of the system with its original control strategy based on classical indirect vector control strategy...

[1] Permanent scatterer InSAR (PSInSARk) provides a new high-resolution methodology for detecting and precisely measuring long-term and seasonal aquifer-system response to pumping and recharge. In contrast to conventional InSAR, the permanent scatterer methodology utilizes coherent radar phase data from thousands of individual radar reflectors on the ground to develop displacement time series a...

In this study the network of ATP-consuming and -producing reactions, interacting via the cytosolic ATP/ADP+P(i) system, was studied for the first time in an intact organ, the isolated perfused rat liver, using top-down metabolic-control analysis. Flux control in the metabolically resting state (only oxidative phosphorylation and ion pumps active) was only in the ATP-consumers, whereas in the me...

[1] Groundwater pumping has caused excessive groundwater depletion around the world, yet regulating pumping remains a profound challenge. California uses more groundwater than any other U.S. state, and serves as a microcosm of the adverse effects of pumping felt worldwide—land subsidence, impaired water quality, and damaged ecosystems, all against the looming threat of climate change. The state...
