Refinement

open access: yesALTEX, 2014
The ultimate goal of the Three Rs is the full replacement of animals used in biomedical research and testing. However, replacement is unlikely to occur in the near future; therefore the scientific community as a whole must continue to devote considerable effort to ensure optimal animal welfare for the benefit of the science and the animals, i.e., the R

Adaptive NMS: Refining Pedestrian Detection in a Crowd [PDF]

open access: yesComputer Vision and Pattern Recognition, 2019
Pedestrian detection in a crowd is a very challenging issue. This paper addresses this problem by a novel Non-Maximum Suppression (NMS) algorithm to better refine the bounding boxes given by detectors.

Optimization of the reaction parameters of heavy naphtha reforming process using Pt-Re/Al2O3 catalyst system

open access: yesEgyptian Journal of Petroleum, 2017
One of the most significant procedures in oil refineries is naphtha catalytic reforming unit in which high octane gasoline is gained. Normally, in oil refineries, flow instability in the composition of feedstock can affect the product quality. The aim of

Fit-for-Use Nanofibrillated Cellulose from Recovered Paper

open access: yesNanomaterials, 2023
The cost-effective implementation of nanofibrillated cellulose (CNF) at industrial scale requires optimizing the quality of the nanofibers according to their final application. Therefore, a portfolio of CNFs with different qualities is necessary, as well

Oxidative Stability of Virgin and Refined Argan [Argania spinosa L. (Skeels)] Oil under Accelerated Aging Conditions and Shelf-Life Prediction at Room Temperature: A Comparative Study

open access: yesAnalytica, 2023
Argan kernels, fruits regurgitated by goats, are 30% cheaper than the regular kernels used to prepare food argan oil. The use of such argan kernels as a cosmetic ingredient, after refining, is thus economically attractive.

Effects of Solvent Concentration on Refining (Degumming, Dewaxing, and Deacidification) of Canola Oil Using Membrane Filtration [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2023
Miscellas of canola were obtained by mixing its crude oil with hexane solvent at 80:20 and 70:30 ratios. Then, 16.1 M of phosphoric acid and 6.92 M of sodium hydroxide were mixed with the resulting micelles at 0.3% (w/w for degumming) and 13% (w/w for ...

Refinement of Intentions [PDF]

open access: yes, 2016
According to Bratman, future-directed intentions are high-level plans. We view such plans as high-level actions that can typically not be executed directly: they have to be progressively refined until executable basic actions are obtained. Higher- and lower-level actions are linked by the means-end relation, alias instrumentality relation.

Refining Action Segmentation with Hierarchical Video Representations

open access: yesIEEE International Conference on Computer Vision, 2021
In this paper, we propose Hierarchical Action Segmentation Refiner (HASR), which can refine temporal action segmentation results from various models by understanding the overall context of a given video in a hierarchical way.
