Journal of Applied Polymer Science, Volume 140, Issue 2, January 10, 2023., 2023 Abstract The characteristic time periodicity τ* and the spatial characteristic wavelength λ of extrusion flow instabilities of a linear and a branched commercial polyethylene (PE) are characterized via capillary rheology, optical analysis and modeled. The two investigated polyethylenes have the similar weight average molecular weight (Mw).

Women online: A study of Common Service Centres in India using a capability approach
Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 268-287, September 2022., 2022 Abstract Income‐generating activities by women are an effective means of reducing gender‐based deprivation and disparities. In the constrained familial and community settings of developing economies, online platforms can be an appropriate means for women to carry out economic activities. In this context, important initiatives taken by the Government of

Dynamic Online Ensembles of Basis Expansions [PDF]
Transactions on Machine Learning Research (TMLR), 2024Practical Bayesian learning often requires (1) online inference, (2) dynamic models, and (3) ensembling over multiple different models. Recent advances have shown how to use random feature approximations to achieve scalable, online ensembling of Gaussian processes with desirable theoretical properties and fruitful applications. One key to these methods'

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”

Willingness of women‐led businesses in Pakistan to join formal e‐commerce platforms
Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 246-267, September 2022., 2022 Abstract An equitable distribution of economic benefits from the recent growth of e‐commerce in Pakistan requires inclusive adoption of formal digital marketplaces. The available literature and focused discussions reveal that most women‐led businesses rely on informal e‐commerce managed through social media applications and have incomplete and often ...

Solution of boundary value problems for batteries: Operator‐theoretic methods
AIChE Journal, EarlyView.Abstract Batteries with porous electrodes of negligible ionic and electronic conduction resistance are modeled with reaction‐diffusion equations in multilayered media. The classical separation of variables becomes inapplicable to battery problems because of nonlinearities in reaction rates and constraints of imposed current. A linear operator‐theoretic
