Robust three-dimensional best-path phase-unwrapping algorithm that avoids singularity loops [PDF]

, 2009
In this paper we propose a novel hybrid three-dimensional phase-unwrapping algorithm, which we refer to here as the three-dimensional best-path avoiding singularity loops (3DBPASL) algorithm.

The effect of the accuracy of determining the angular ratios of the vectors of a three-phase system on the error of estimating symmetric components

Вестник Северо-Кавказского федерального университета
Introduction. Analysis of the quality of electricity based on indicators characterizing voltage asymmetry using the classical method of symmetrical components involves measuring not only an assessment of the voltage modules of a three-phase system, but ...

Experimental study of the asymmetry of a three-phase stress system [PDF]

Научно-технический вестник Брянского государственного университета, 2018
“Arduino” allows the computer to simulate the electrical load. Devices using “Arduino” receive sensor information and control the actuators. The platform, with software code, is built on a simple board with a modern environment for writing software. This

Electronic Load System With Interleaved Structure Applicable to DC, Single-Phase AC, and Three-Phase AC

IEEE Access, 2022
We propose an electronic load system with an interleaved structure applicable to DC, single-phase AC, and three-phase AC. Applying the interleaved method makes it possible to reduce voltage and current ripple, thereby reducing voltage and current stress ...

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Reduced Reference Frame Transformation Assessment in Unbalanced Three-Phase Four-Wire Systems

IEEE Access, 2023
Three-phase four-wire systems require a reference frame similar to that used in 3-phase 3-wire system configurations that allow them to be easily analysed, modelled and controlled.

Provider and Parent Perspectives on Prioritizing the “Asking and Monitoring” Pediatric Cancer Psychosocial Standards of Care

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The Standards for Psychosocial Care for Children with Cancer and Their Families (“Standards”) are evidence‐based guidelines for psychosocial care in pediatric oncology. Care related to the three “Asking and Monitoring” Standards—Assessment of Psychosocial Needs, Assessment of Financial Needs, and Monitoring Neurocognitive Problems ...

Topology Optimization Analysis of Leakage Current Suppression in Three-Level Four-Leg Photovoltaic Grid-Connected Inverter

IEEE Access, 2023
The grid-connected non-isolated photovoltaic inverter system suffers from the leakage current, which increases the loss of the system, and the grid-connected current harmonics impact the normal operation of the equipment.

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distributed a 121‐question survey to radiation oncologists, medical physicists and ...
