Diagnostic feature extraction with consideration of interactions between variables is very important, but has been neglected in most diagnostic research. In this paper, a new feature extraction methodology is developed to consider variable interactions by using a fractional factorial design of experiments (DOE). In this methodology, features are extracted by using principal component analysis (...
A recurring obstacle for structural genomics is the expression of insoluble, aggregated proteins. In these cases, the use of alternative salvage strategies, like in vitro refolding, is hindered by the lack of a universal refolding method. To overcome this obstacle, fractional factorial screens have been introduced as a systematic and rapid method to identify refolding conditions. However, metho...
BACKGROUND AND THE PURPOSE OF THE STUDY Lamotrigine (LMG) undergoes extensive hepatic metabolism upon oral administration and its absorption is affected in the presence of food. This study was aimed to develop nanosuspension of LMG and investigate its formulation characteristics using L(9) orthogonal array. METHODS Nanosuspension was prepared using emulsification-solvent diffusion method. All...
The COVID-19 pandemic has created a worldwide healthcare crisis. Convolutional Neural Networks (CNNs) have recently been used with encouraging results to help detect from chest X-ray images. However, generalize well unseen data, CNNs require large labeled datasets. Due the lack of publicly available datasets, most apply various data augmentation techniques during training. there not thorough st...
Optimization of spin-coat parameters of a spin-ondielectric (SOD) onto a substrate is investigated using a two level fractional factorial design of experiment. Five parameters, spin rate, spin time, number of spin coats, volume of SOD, and the softbake temperature were varied to determine the main effect on the thickness of the deposited layers as a quality check. The layer thickness was measur...
This note builds on results from Wu, Mee and Tang‘s (2012) article (henceforth WMT) on admissible fractional factorial two-level designs, specifically concentrating on the “dominating designs” that have been introduced but not further pursued in WMT. WMT’s work has been used for increasing the efficiency of the author’s graph-based algorithm for creation of minimum aberration designs that keep ...
