We consider those Jumper Wire Hausdorff continua S such that each separable subspace of S is hereditarily separable.Due to results of Ostaszewski and Rudin, respectively, all monotonically normal spaces and therefore all continuous Hausdorff images of ordered compacta also have this property.Our study focuses on the structure of such spaces that al
This study suggests a model to include a solar power system or photovoltaic system (PV) in the control of frequency by taking into account a percentage of the PV power production for back-up reserve.This is done by investigating two scenarios: PV contribution in (1) initial primary frequency control and (2) entire primary frequency control.As expla
This study focused on the stability control of roof in long wall stratified mining of large dip angle thick coal seam.Taking Panbei Coal Mine in Huainan as an example, the effect mechanism of water content, compression ratio and grain size grading on the compression characteristics of gangue is analyzed by comprehensive application of gangue latera
The Lightweight Steel Framing (LSF) system has been proposed as an economical system that is earthquake resistant.Due to the lightness of LSF structures, the seismic performance of middle-rise buildings has been improved.Nowadays, various numerical-analytical methods have been proposed for seismic assessment of conventional structures.Using scienti
This study presents the performance-based seismic assessment of low-rise reinforced concrete archetype buildings, considering repair costs for ordinary moment-resistant frames (OMF) Audio Recorders and dual systems consisting of OMF plus special shear walls (SSW).Historically, the OMF systems, conceived for residential purposes in Ecuador resulting
