Wind-Turbine and Wind-Farm Flows: A Review [PDF]

Boundary-Layer Meteorology, 2019
AbstractWind energy, together with other renewable energy sources, are expected to grow substantially in the coming decades and play a key role in mitigating climate change and achieving energy sustainability. One of the main challenges in optimizing the design, operation, control, and grid integration of wind farms is the prediction of their ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Re‐Irradiation in Pediatric Diffuse Midline Glioma: A Multi‐Institutional Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with recurrent diffuse midline gliomas (DMGs) have limited therapeutic options at recurrence. Re‐irradiation (RT2) may be used at progression, but with uncertainty about the benefit. Methods We conducted a multi‐institutional retrospective study of children aged < 18 with DMG treated at three centers (Toronto, Canada ...

GENERAL CALCULATION OF WINDING FACTOR FOR MULTI-PHASE/-LAYER ELECTRICAL MACHINES IRRESPECTIVE OF POLES NUMBER

Acta Polytechnica, 2019
In this paper, a method to calculate the winding factor by only considering stator parameters without the rotor ones is developed. This is interesting because it allows the separation of the stator and rotor design, unlike the existing methods in the ...

Dynamic investigation of Georges phenomenon related to three-phase wound-rotor induction motor

Journal of Electrical Systems and Information Technology, 2020
The aim of this paper is to analyze the performance of a three-phase wound-rotor induction motor (WRIM) under rotor windings asymmetry. The dynamic performance of the WRIM under healthy and rotor windings asymmetry with one-open-phase fault conditions is

‘Wind, Wind, Wind, Always Winding Am I’: Dickens’s Metafictional Clockwork

The Review of English Studies, 2022
Abstract This article considers the importance of timepieces and clockwork to Dickens’s conception of composition. Whilst the many clocks and watches that saturate his writing have often been read as indicative of an interest in time, the present study considers what the materiality of timepieces—namely, their markets and mechanisms ...

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.

Wind Winding Down [PDF]

Science, 2011
Climate Science Increasing concentrations of greenhouse gases in the atmosphere, emitted by human activities, have caused Earth's climate to warm. Climate warming has been linked to a host of other environmental changes, one of the most evident being an increase in the amount of water present ...
