Factorial design to obtain magnetized poly(ethyl acrylate-co-divinylbenzene)

Polímeros
Magnetized polymers are produced by incorporating magnetic particles in a polymeric matrix. This article describes the use of the suspension polymerization technique using ethyl acrylate and divinylbenzene as monomers, in the presence of heptane and/or ...

Balanced Factorial Designs

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1966
Summary Kurkjian and Zelen (1963) have proved that factorial designs possessing a particular structure for their C matrix (they call this property A) are factorially balanced. This paper proves the converse of this result, viz. factorially balanced designs are (a) EGD/(2n - 1)-PBIB designs as defined by Hinkelmann (1964), and (b) possess

The design and analysis of factorial experiments [PDF]

, 1937
Factorial experiments are experiments which include all combinations of several different sets of treatments or "factors." Information is thus simultaneously obtained on the responses to the different factors, and also on the effects of changes in the ...

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

Optimization of MCM-48 synthesis using factorial design

Cerâmica
MCM-48 mesoporous materials were hydrothermally synthesized according to the 22 factorial design by varying the crystallization time and temperature of the synthesis gel, and characterized by means of X-ray diffraction analysis and adsorption of N2.

Requests from Companies and Requirements for Design Education in Brazil: where do they meet? [PDF]

, 2018
In this paper, we study what companies request from applicants for graphic design positions in Brazil. Based on a document analysis of 371 job advertisements, we uncover 35 different types of requests which we structure in terms of (1) Design ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Generation of Factorial Designs

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1976
Summary This paper describes a method for generating asymmetrical factorial designs given specified relationships between the levels of treatment and plot factors. Comparisons are made with a generalized cyclic method (John and Dean, 1975) for single replicate designs.
