Objective.This article aims at identifying the genesis of the studies the conceptual model Functional Requirements for Bibliographic Records (FRBR), published in 1998 by the International Federation of Library Associations and Institutions (IFLA) with the proposal to develop new approach to the bibliographic record.Method.For this appealed to bibli
The symmetrical bipolar configuration shows a great advantage in modular multilevel converter (MMC) based high-voltage dc-current (HVDC) transmission.In a bipolar MMC-HVDC system, station internal ac grounding faults cause sub-module (SM) capacitors to discharge violently.These faults do great harm to MMCs and require special protection schemes.In
Background: The healthcare sector faces increasing pressure to improve environmental sustainability whilst continuing to meet the needs of patients.One strategy is to lower the avoidable demand on healthcare services, by reducing the number of surgical complications, such as anastomotic leak (AL).The aim of this study was to assess the environmenta
This article presents a modular substrate-integrated waveguide (SIW) antenna array based on H-plane aperture structures for Ka-band.The unitary antenna is based on a SIW aperture antenna with an improved H-plane radiation pattern by means of the implementation of metallic vias in the wave propagation along the H-plane antenna.The inner metallic via
The increasing penetration of cushcraft ar-10 solar energy into the grid has led to management difficulties that require high accuracy forecasting systems.New techniques and approaches are emerging worldwide every year to improve the accuracy of solar power forecasting models and reduce uncertainty in predictions.This article aims to evaluate and c
