Evaluation and Design of a SiC-Based Bidirectional Isolated DC/DC Converter
… at different power levels. Under forward mode operation, a peak efficiency of 98.3% at 15 kW was recorded, along with a full load efficiency value of 98.1% at 25 kW. Under reverse mode operation, a peak efficiency of 98.8% was measured at 17.8 kW. The full load efficiency at 25 kW under …

Algorithmic differentiation of Java programs
… these AD transformations in the forward mode, for the scalar and vector modes alike, with support for the entire Java 2 Math library. Moreover, ADiJaC deals with the new issues appearing in the semantics of automatic differentiation transformations due to problems such as the need to …

Differentiable visual computing
… extend the image processing language Halide with reverse-mode automatic differentiation, and the ability to automatically optimize the gradient computations. This enables automatic generation of the gradients of arbitrary Halide programs, at high performance, with little programmer effort.

Computational design for electromagnetic simulations
… for computing sensitivity derivatives employs a reverse-mode time-accurate discrete adjoint methodology that is formulated to automatically maintain consistency with the electromagnetic field simulation software. Grid smoothing is achieved using a spatially higher-order accurate Galerkin …

Regulation des Na+/Ca2+-Austauschers in kultivierten Podozyten der Maus
… Er arbeitet in zweierlei Modi: dem Forward Mode und dem Reverse Mode. Letzterer dient dem Ca2+-Export nach einem transienten Anstieg der intrazellulären Ca2+-Konzentration, sei es im Rahmen physiologischer Vorgänge (Signaltransduktion), oder aber in der Folge einer zellulären Schädigung. …

Lead Activation of a Developmentally Regulated Calcium Channel in Rat Hippocampal Nerve Terminals
… exchange operating in the "reverse" mode. Low concentrations of Pb<sup>2+</sup> (0.1-0.5 μΜ ) blocked competitively both the rapidly and slowly inactivating channels. At higher concentrations (≥1μΜ) , Pb<sup>2+</sup> permeated the rapidly inactivating channels. …

Flow phenomena in fixed-gap and gravure roll coating systems
… problem, considered experimentally, is that of reverse roll coating with a liquid reservoir positioned directly above horizontally aligned rollers. Measurements of the film thickness as a function of the height of fluid in the reservoir and speed ratio are presented. When the wetting line is …

Development and applications of electrically driven separation methods.
… combines the simplest capillary electrophoresis mode where separations are based on the differences in the electrophoretic migration of charged analytes under the influence of a high electric field with separation based on analyte partitioning between the mobile phase and stationery phase from …

Alpha-T-T and T-T-alpha-T diagrams in intelligent processing of thermosetting composites
The majority of existing models for processing in thermoset matrix composites concentrate nearly exclusively on heat and mass transfer problems and account for material-related aspects in a very simplified manner The objective of this work is to provide that missing element by proposing a clearly …

A Modular Framework for Generation and Maintenance of Adjoint Solvers Assisted by Algorithmic Differentiation - with Applications to an Incompressible Navier-Stokes Solver
… is subsequently assembled utilizing a library of reverse mode differentiated routines generated by the algorithmic differentiation (AD) tool TAPENADE. The proposed technique is applied to an unstructured incompressible finite volume flow solver, which implements a segregated pressure correction …

Tri-helical direct gravure coating
Tri-helical, gravure roll coating, operated in reverse mode, is investigated via a combined experimental, theoretical and computational approach. New experiments were conducted on a pilot coating rig, designed to simulate the industrial process. Flow visualisations reveal the underlying flow …

Spatial organization of sodium calcium exchanger and caveolin-3 in developing mammalian ventricular cardiomyocytes
… suggests an additional CICR modality involving reverse mode Na+-Ca2+ exchanger (NCX) activity also exists in neonate cardiomyocytes. To further our understanding of how CICR changes occur during development, we investigated the spatial arrangement of caveolin-3 (cav-3), the principle structural …

Automatic differentiation of the CapeML high-level language for process engineering
To perform computer simulations of the modeled phenomena the mathematical description the model needs to be implemented as a computer program, and often the choice of implementation language depends on the simulation environment chosen. This dependency of the programming language and the simulation …
