Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion
AIChE Journal, EarlyView.Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

A New Concept of a Drug Delivery System with Improved Precision and Patient Safety Features
Micromachines, 2014 This paper presents a novel dosing concept for drug delivery based on a peristaltic piezo-electrically actuated micro membrane pump. The design of the silicon micropump itself is straight-forward, using two piezoelectrically actuated membrane valves as ...

Bayesian model averaging in model-based clustering and density estimation [PDF]
arXiv, 2015 We propose Bayesian model averaging (BMA) as a method for postprocessing the results of model-based clustering. Given a number of competing models, appropriate model summaries are averaged, using the posterior model probabilities, instead of being taken from a single "best" model.

Bond graphs in model matching control [PDF]
, 2006 Bond graphs are primarily used in the network modeling of lumped parameter physical systems, but controller design with this graphical technique is relatively unexplored.

Cake formation in the filtration of associative microgel suspensions
AIChE Journal, EarlyView.Abstract In this work, we investigate the jamming behavior of associative microgel suspensions used as fluid loss additives in model porous media. We first construct a phase diagram using drying experiments, followed by characterization of the suspensions' rheology and the permeability of the filter cakes at maximum microgel concentration. Microfluidic

arXiv, 2016 We provide a survey on relational models. Relational models describe complete networked {domains by taking into account global dependencies in the data}. Relational models can lead to more accurate predictions if compared to non-relational machine learning approaches.

Towards Automatic Support of Software Model Evolution with Large Language~Models [PDF]
arXiv, 2023 Modeling structure and behavior of software systems plays a crucial role, in various areas of software engineering. As with other software engineering artifacts, software models are subject to evolution. Supporting modelers in evolving models by model completion facilities and providing high-level edit operations such as frequently occurring editing ...

Distributed and Lumped Parameter Models for Fuel Cells
, 2020 The chapter presents a review of modeling techniques for three types of fuel cells that are gaining industrial importance, namely, polymer electrolyte membrane (PEMFC), direct methanol (DMFC), and solid oxide (SOFC) fuel cells (FCs). The models presented are both multidimensional, suitable for investigating distributions, gradients, and inhomogeneities

Advanced Intelligent Systems, EarlyView.The study presents a method for detecting touch location and force magnitude on soft capacitive sensors without complex electrode patterning. Multifrequency impedance measurements are combined with machine learning to accurately classify five sensing zones and estimate applied force with low error.
