The research aim is to investigate the performance of novel enriched mineral fibres (Filava) in polysiloxane SLIRES H62 resin. Specimens were manufactured using a vacuum bagging process and oven cured at 250 °C. prepared for flexural testing according BS EN ISO 14125:1998 obtain strength, modulus, elongation. mechanical strength was compared similar composites, with determining composite index....

The relation of the Al-Alaoui pattern recognition algorithm to the boosting and bagging approaches to pattern recognition is delineated. It is shown that the Al-Alaoui algorithm shares with bagging and boosting the concepts of replicating and weighting instances of the training set. Additionally it is shown that the Al-Alaoui algorithm provides a Mean Square Error, MSE, asymptotic Bayesian appr...

Graphene aerogels (GAs) are prevailing to solve electromagnetic interference (EMI) issues in next-generation electronic devices. However, the practical EMI shielding application of lightweight GAs is still a great challenge because their structural instability when confronted with complex conditions. Here, we report class ultra-stable excellent and reliable performances. The GA (ρ = 3.7 mg cm−3...

Material experts are striving to use natural resources as skin and core in composite sandwiches achieve light weight, biodegradability, cost benefits. This paper reports one such newly developed green sandwich its biodegradable behavior. The of flax fiber agglomerated cork respectively. is manufactured by vacuum bagging technique order get higher volume fraction fiber. biodegradability testing ...

in the present work, deoxidation and refining of 316lvm steel (low carbon vacuum melted) during the vacuum induction melting process was studied. this grade of stainless steel is one of the most important materials in medical applications. vacuum deoxidation by carbon is the first stage of 316lvm stainless steel production process. in this stage, aluminum must be absent to avoid killing the c-o...

purpose: to evaluate the effect of vacuum and flow rate on endothelial cell loss after high versus low vacuum phacoemulsification. methods: this randomized clinical trial was performed on 60 eyes of 60 patients with moderate lens opacity (nuclear sclerosis 3+). all surgeries were performed by one experienced surgeon using stop and chop technique with sovereign white star machine (amo). patients...

Earthquakes will do great harms to the people, to estimate the future earthquake situation in Chinese mainland is still an open issue. There have been previous attempts to solve this problem by using artificial neural networks. In this paper, a novel algorithm named MIFEB is proposed to improve the estimation accuracy by combing bagging of neural networks with mutual information based feature s...

Stratified sampling is often used in opinion polls to reduce standard errors, and it is known as variance reduction technique in sampling theory. The most common approach of resampling method is based on bootstrapping the dataset with replacement. A main purpose of this work is to investigate extensions of the resampling methods in classification problems, specifically we use decision trees, fr...

We experimentally evaluate bagging and seven other randomization-based approaches to creating an ensemble of decision-tree classifiers. Unlike methods related to boosting, all of the eight approaches create each classifier in an ensemble independently of the other classifiers in the ensemble. Bagging uses randomization to create multiple training sets. Other approaches, such as those of Dietter...

Comparing different novel feature sets and classifiers for speech processing based fatigue detection is the primary aim of this study. Thus, we conducted a within-subject partial sleep deprivation design (20.00–04.00 h, N1⁄477 participants) and recorded 372 speech samples of sustained vowel phonation. The self-report on the Karolinska Sleepiness Scale (KSS) and an observer report on the KSS, th...
