Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

Advanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Computational optimization, modelling and simulation–a paradigm shift

Procedia Computer Science, 2010
AbstractComputational optimization forms an integrated part of modern computational science. Any good design should intend to achieve certain optimality, though optimal solutions are often difficult to find in practice since uncertainty and nonlinearity always present in almost all real-world problems.

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Experiments in concurrent stochastic simulation: The EcliPSe paradigm

Journal of Parallel and Distributed Computing, 1992
Abstract This paper presents results on the performance of a novel and flexible concurrent simulation environment known as EcliPSe . The paradigm we advocate is based on the premise that replication based simulations, either nondistributed or minimally distributed, yield excellent speedups.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Analysis of provably secure on-demand source routing in MANET

Tongxin xuebao, 2009
A formal model tailored to the security analysis of on-demand source routing protocols in MANET was analyzed, and the improper manipulations such as mergence of the adjacent adversarial nodes in the model and the flaw in the proof for endairA were ...

Simulating paradigm shifts using a lock-in model [PDF]

, 1998
In this paper, we extend Brian Arthur's original lock-in model of increasing returns to adoption with a changing rate of technical change within competing technologies. This is done by including an S-curve in the pay-off function of alternatives reflecting the stage of the life-cycle of each "paradigm" in terms of its problem-solving capacity ...
