A practical approach to switching-loss reduction in a large-capacity static VAr compensator based on voltage-source inverters [PDF]
, 2000 This paper presents a simple method for reduction of switching and snubbing losses in a large-capacity static VAr compensator (SVC) consisting of multiple three-phase voltage-source square-wave inverters.

Differences between downhole and surface micro-seismic monitoring [PDF]
, 2015 The article presents usage of microseismic monitoring for location of microseismic events in polish geological conditions. For location of one synthetic microseismic event, two methods of acquisition were applied: surface and downhole monitoring array ...

Energy Science &Engineering, EarlyView.Formed ~1.4 Ga, the carbonate reservoir of the Jixian System is a key geothermal reservoir in northern China. Differential basin–mountain evolution since the Cenozoic led to distinct reservoir‐forming histories; consequently, this same reservoir shows marked productivity contrasts between intramontane basins and the large rift Bohai Bay Basin ...

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Integrating distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) data with numerical simulations to analyze inter‐well interference and production responses remains challenging. This study employs a coupled thermal–hydraulic–mechanical simulation framework to model heat transfer, fluid flow, and geomechanical responses ...

Magnetic Resonance in Chemistry, Volume 64, Issue 11, Page 917-929, November 2026.Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract The nature of mantle sections exhumed at magma‐poor rifted margins remains poorly constrained, largely because direct sampling of mantle in modern passive margins is exceptionally rare. The Iberia–Newfoundland system is unique in providing drilled mantle rocks on both conjugate margins, offering an unprecedented glimpse into mantle ...
