Shape Optimization of a Two-Fluid Mixing Device Using Continuous Adjoint
, 2020 In this paper, the continuous adjoint method is used for the optimization of a static mixing device. The CFD model used is suitable for the flow simulation of the two miscible fluids that enter the device.

Review of continuous adjoint method for inverse design of indoor thermal environment
, 2022 The continuous adjoint method has been used in the indoor environment for more than ten years, but it has not been widely used up to now. This paper describes the current state of the continuous adjoint method and presents an overview of the continuous ...

A data assimilation model for turbulent flows using continuous adjoint formulation
The Physics of Fluids, 2018 A generalized data assimilation model for turbulent flows using the continuous adjoint formulation is proposed. Within this formulation, the Spalart–Allmaras turbulence model is modified by adding a correction function β as a spatially varying ...

Topology optimization for magnetic circuits with continuous adjoint method in 3D
CompelPurpose The purpose of this paper is to present a new approach to optimizing the design of 3D magnetic circuits. This approach is based on topology optimization, where derivative calculations are performed using the continuous adjoint method.

Continuation Semantics and Self-adjointness
Electronic Notes in Theoretical Computer Science, 1997 AbstractWe give an abstract categorical presentation of continuation semantics by taking the continuation type constructor ¬ (or cont in Standard ML of New Jersey) as primitive. This constructor on types extends to a contravariant functor on terms which is adjoint to itself on the left; restricted to the subcategory of those programs that do not ...

Adjoint bi-continuous semigroups and semigroups on the space of measures [PDF]
Czechoslovak Mathematical Journal, 2011 For a given bi-continuous semigroup T on a Banach space X we define its adjoint on an appropriate closed subspace X^o of the norm dual X'. Under some abstract conditions this adjoint semigroup is again bi-continuous with respect to the weak topology (X^o,X).

Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI
Advanced Science, EarlyView.ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

Advanced Intelligent Discovery, EarlyView.This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

Continuous Adjoint Shape Optimization of Internally Cooled Turbine Blade
, 2021 This paper presents an adjoint-based shape optimization framework and its demonstration in a Conjugate Heat Transfer problem in a turbine blading. The gradient of the objective function is computed based on the continuous adjoint method which also ...
