3D Cruise Trajectory Optimization Inspired by a Shortest Path Algorithm

Aerospace, 2020
Aircrafts require a large amount of fuel in order to generate enough power to perform a flight. That consumption causes the emission of polluting particles such as carbon dioxide, which is implicated in global warming.

Modeling of Pore Coarsening in the Rim Region of High Burn-up UO2 Fuel

Nuclear Engineering and Technology, 2016
An understanding of the coarsening process of the large fission gas pores in the high burn-up structure (HBS) of irradiated UO2 fuel is very necessary for analyzing the safety and reliability of fuel rods in a reactor.

Effect of nonuniform density structure on burn-up ratio of multi-shock-compressed DT fuel in fast ignition

Nuclear Fusion
The burn characteristics of multi-shock-compressed DT fuel under fast ignition conditions are investigated using two-dimensional burn simulations. In solid-sphere implosions, high fuel areal density can be achieved through multi-shock compression with ...

Methodology of Fuel Burn Up Fitting in VVER-1000 Reactor Core by Using New Ex-Vessel Neutron Dosimetry and In-Core Measurements and its Application for Routine Reactor Pressure Vessel Fluence Calculations

EPJ Web of Conferences, 2016
Paper describes the new approach of fitting axial fuel burn-up patterns in peripheral fuel assemblies of VVER-1000 type reactors, on the base of ex-core neutron leakage measurements, neutron-physical calculations and in-core SPND measured data.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Assessing Consistency in Fuel Consumed Between Activity‐Based Wildfire Emission Estimates

Geophysical Research Letters
Wildfire emission inventories exhibit large variability that complicates assessments of smoke impacts. Here we compare fuel consumed (in mass per burned area units) from multiple burn area‐based and energy‐based approaches for fires in the western US ...
