Computation of aircraft component flow fields at transonic Mach numbers using a three-dimensional Navier-Stokes algorithm [PDF]
A computer analysis was developed for calculating steady (or unsteady) three-dimensional aircraft component flow fields. This algorithm, called ENS3D, can compute the flow field for the following configurations: diffuser duct/thrust nozzle, isolated wing,

Public Administration and Development, EarlyView.ABSTRACT Although some studies focus on how bureaucrats' interactions with one another affect performance, they rarely focus on why these public servants collaborate. Bureaucrats' collaboration matters because it can significantly contribute to achieving policy goals.

Embodied urban design: Fostering nature connectedness for pro‐conservation behaviour
People and Nature, EarlyView.Abstract Those who feel more connected with nature are more likely to act in ways that support biodiversity. How connected people feel with nature depends in part on how meaningfully it figures into their experience of the built environment. Despite an increase in urban greening measures, these approaches often overlook how people perceive, interact ...

Extension of a three-dimensional viscous wing flow analysis user's manual: VISTA 3-D code [PDF]
Three-dimensional unsteady viscous effects can significantly influence the performance of fixed and rotary wing aircraft. These effects are important in both flows about helicopter rotors in forward flight and flows about three-dimensional (swept and ...

A structurally localized ensemble Kalman filtering approach
Quarterly Journal of the Royal Meteorological Society, EarlyView.We derive an inherently localized ensemble Kalman filtering (EnKF) approach, avoiding the need for any auxiliary localization technique. The idea is to first use the variational Bayesian optimization to approximate the (continuous) state analysis probability density function (pdf) by a product of independent marginal pdfs corresponding to small ...

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT In this paper, we consider the optimal control problem for an unknown continuous‐time nonlinear system, and present a framework that integrates model‐based and model‐free methods to solve it. Each approach offers distinct advantages: model‐based techniques provide offline synthesis and data efficiency, while model‐free procedures excel at ...

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning
Journal of Field Robotics, EarlyView.ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.

Time-asymptotic solutions of the Navier-Stokes equation for free shear flows using an alternating-direction implicit method [PDF]
An uncoupled time asymptotic alternating direction implicit method for solving the Navier-Stokes equations was tested on two laminar parallel mixing flows.

Documentation of nearshore interactive wave - current - topography change models [PDF]
, 1992 This report is to document the programs my colleague and I developed for computing time-dependent nearshore hydrographic changes including beach profile responses. The time scale of the model is suitable for storm events to seasonal changes, currently
