, 2008 The inherent stochastic character of most of the physical quantities involved in engineering models has led to an always increasing interest for probabilistic analysis. Many approaches to stochastic analysis have been proposed. However, it is widely acknowledged that the only universal method available to solve accurately any kind of stochastic ...

Journal of Applied Polymer Science, Volume 140, Issue 2, January 10, 2023., 2023 For graphene/PP nanocomposites that contain graphene agglomeration, we construct a two‐scale geometrical model including graphene‐rich and graphene‐poor regions. The volume fraction of graphene agglomerates is assessed by the shear yield strength. To take into account the influence from interface between graphene and PP, we build a “coated filler ...

Journal of Applied Polymer Science, Volume 140, Issue 5, February 5, 2023., 2023 The COVID‐19 pandemic led to a backlog of filtration material for N95 Filtering Facepiece Respirators (FFRs). An alternative face mask filter material is presented, consisting of an unsupported, nonwoven layer of uncharged polystyrene microfibers. This microfiber material meets NIOSH N95 FFR filtration and breathability requirements, demonstrates ...

Few-shot crack image classification using clip based on bayesian optimization [PDF]
arXivThis study proposes a novel few-shot crack image classification model based on CLIP and Bayesian optimization. By combining multimodal information and Bayesian approach, the model achieves efficient classification of crack images in a small number of training samples.

Popular political attitudes in Samoa: Findings of the Pacific Attitudes Survey
Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 408-429, September 2022., 2022 Abstract Popular political attitudes surveys have been conducted globally for several decades, but the Pacific region remains an exception. This paper presents the findings of the first Pacific Attitudes Survey (PAS), conducted in Samoa from December 2020‐January 2021.

Prescribed performance control approaches, applications and challenges: A comprehensive survey
Asian Journal of Control, Volume 25, Issue 1, Page 241-261, January 2023., 2023 Abstract As to control systems, transient performance is as important as steady‐state performance. For some special dynamic systems, transient performance is a more prior index in comparison with the steady‐state one. Prescribed performance control (PPC) has been proved to be a powerful tool that guarantees control system outputs/errors with desired ...

AIChE Journal, EarlyView.Abstract Integrated dynamic scheduling (IDS) and economic nonlinear model predictive control (eNMPC) enable economic operation of chemical plants subject to volatile energy prices. Herein, we combine the two concepts into an integrated two‐layer scheme. Therein, IDS performs “long‐horizon” scheduling on a day‐ahead (DA) market and eNMPC “short‐horizon”

Generalized optimization framework for synthesis of thermally coupled distillation columns
AIChE Journal, EarlyView.Abstract In this article, a generalized optimization framework is proposed for the synthesis of thermally coupled distillation systems within an equation‐oriented environment. The proposed framework consists of three components: an efficient superstructure representation, a novel mathematical formulation, and the associated solution algorithm ...
