Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

open access: yesAdvanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Hierarchical Reasoning Model

open access: yesCoRR
Reasoning, the process of devising and executing complex goal-oriented action sequences, remains a critical challenge in AI. Current large language models (LLMs) primarily employ Chain-of-Thought (CoT) techniques, which suffer from brittle task ...

Hierarchical Models

Bayesian Econometric Methods, 2019
Hierarchical models are central to many current analyses of functional imaging data including random effects analysis, models using fMRI as priors for EEG source localization and spatiotemporal Bayesian modelling of imaging data [3].

Introduction to Hierarchical Modeling

Journal of Palliative Medicine, 2009
Hierarchical modeling (HM) is a statistical technique that has gained in popularity in health care research. It has been used for analysis of secondary data, performance profiles or benchmarking studies, and in prospective trials. The technique is used in situations in which traditional regression analysis might lead to incorrect conclusions ...

Models of Hierarchal Replacement

IEEE Transactions on Reliability, 1979
Replacement problems can take a wide variety of forms. We discuss techniques which can be applied to a rather broad class of problems, including as special cases many practical situations. The models incorporate allowances for both-i) replacement from aging stocks, ii) hierarchal structures for replacement elements of different kinds. For the most part,

Hierarchical morphable models

Proceedings. 1998 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (Cat. No.98CB36231), 2002
This paper presents a new technique for modelling object classes (such as faces) and matching the model to novel images from the object class. The technique can be used for a variety of image analysis applications including face recognition, object verification and facial expression analysis.

Hierarchical System Modeling

IEEE Transactions on Fuzzy Systems, 2018
In this study, we present a methodology of building a hierarchical framework of system modeling by engaging concepts and design methodology of granular computing. We demonstrate that it arises as a result of designing and using locally constructed models to develop a model of a global nature.
