Structural Studies of Penetrated Ion Pairs Using Chiral Cyanine Borates
… structural evidence suggests that a nitrogen-forward mode for penetration by the cyanine dominates the solution behavior. A critical feature for the detection of the induced circular dichroism spectrum is that the dye is twisted in the ground state. The free energy difference between the …

Regulation des Na+/Ca2+-Austauschers in kultivierten Podozyten der Maus
… beteiligt. 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 …

On Model- and Data-based Approaches to Structural Health Monitoring
… difficulties associated with the numerical modelling of physical systems; and limited understanding of the physical effect of system inputs (including environmental and operational loads). This thesis focuses on the roles of law-based and data-based modelling in current applications of. …

Evaluation and Design of a SiC-Based Bidirectional Isolated DC/DC Converter
… were captured 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 …

Algorithmic differentiation of Java programs
… tool implements 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 …

Three-Phase and Unidirectional Heat Transfer
… the other is smooth and hydrophobic. In the forward mode of operation, water evaporates from the heated wicked plate and condenses on the opposing hydrophobic plate. The large contact angle of the dropwise condensate enables bridging across the gap to replenish the wicked evaporator, …

A Modular Framework for Generation and Maintenance of Adjoint Solvers Assisted by Algorithmic Differentiation - with Applications to an Incompressible Navier-Stokes Solver
… 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 SIMPLE …

Sensitivity analysis for nonsmooth dynamic systems
Nonsmoothness in dynamic process models can hinder conventional methods for simulation, sensitivity analysis, and optimization, and can be introduced, for example, by transitions in flow regime or thermodynamic phase, or through discrete changes in the operating mode of a process. While dedicated …

Exploring the emergence of pesticide degradation in the α/β hydrolase superfamily
… ground to observe protein evolution in fast-forward mode. In this global experiment, we can observe the emergence of new enzymatic activities and compare the adaptability of different catalytic motifs. Among the xenobiotic substances used, phosphotriester pesticides range among the most …

Flow phenomena in fixed-gap and gravure roll coating systems
… found to be true. The bead-break instability in forward meniscus coating is considered both experimentally and analytically. Agreement between predictions from a simple mathematical model of the stable bead and experimentally determined meniscus positions is seen to be excellent. A perturbation …

Automatisches Differenzieren für MATLAB
The interactive programming environment MATLAB is increasingly gaining popularity by enabling the user to tackle complicated mathematical problems easily. Implicit dynamic typing and a huge set of predefined functions allow rapid development of - not necessarily prototypical - programs. Under a …

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 …
