A boosting extreme learning machine for nearinfrared spectral quantitative analysis of diesel fuel and edible blend oil samples
Extreme learning machine (ELM) has drawn
increasing attention due to its characteristics of simple structure, high
learning speed and excellent performance. However, a single ELM tends to low
predictive accuracy and instability in dealing with quantitative analysis of
complex samples. To further improve the predictive accuracy and stability of
ELM, a new quantitative model, called boosting ELM is ...

(Analytical and Bioanalytical Chemistry) Identification of Weak Transitions using Moving-Window Two-Dimensional Correlation Analysis: Treatment with Scaling Techniques
In the present study, the theory of the data treatment with scaling techniques for moving-window two-dimensional (scaling-MW2D) correlation analysis was first proposed. This new analytical method of spectroscopy can significantly enhance the resolving capacity of the moving-window two-dimensional (MW2D) correlation infrared spectroscopy in the direction of the perturbation variable. So it streng...

Analysis of petroleum aromatics by laser-induced acoustic desorption/tunable synchrotron vacuum ultraviolet photoionization mass spectrometry.
Laser-induced acoustic desorption coupled with tunable synchrotron vacuum ultraviolet photoionization mass spectrometry (LIAD/SVUVPI-MS) is employed to analyze aromatics prepared under different conditions from Lungu atmospheric residue (LGAR), i.e., the primary aromatics separated directly from LGAR, and the secondary aromatics after hydrogenation of LGAR and its resins. The mass spectra of the...

Methanol oxidation on Ru(0001) for direct methanol fuel cell: Analysis of competitive reaction mechanism
The competitive oxidation reaction mechanism of methanol on the Ru(0001) surface has been investigated by periodic density functional theory (DFT). Stable adsorption configurations, elementary reaction energies and barriers, the potential energy surface (PES), and the electrochemical potential analysis were elucidated. The results showed that O–H bond activation was more competitive than C–H a...

Subagging for the improvement of predictive stability of extreme learning machine for spectral quantitative analysis of complex samples
Extreme learning machine (ELM) has been attracted increasing attentions for its fast
learning speed and excellent generalization performance. However, the prediction
result of a single ELM regression model is usually unstable due to the randomly
generating of the input weights and hidden layer bias. To overcome this drawback,
an ensemble form of ELM, termed as subagging ELM,...

Langmuir, 30, 13615-13621: Why a Lotus-like Superhydrophobic Surface Is Self-Cleaning? An Explanation from Surface Force Measurements and Analysis
The unique self-cleaning
feature of lotus-like superhydrophobic
(SH) surface attracted world-wide interests in recent years. However, the
mechanism of the self-cleaning phenomena remains unclear. Here, we attempt to provide
a comprehensive understanding of why self-cleaning of the particles with a
broad range of size can be realized on the lotus-like SH surfaces. After
measurements and analysis of...

The study of fibre/matrix bond strength in short hemp polypropylene composites from dynamic mechanical analysis
This paper presents results from an experimental study on the static and dynamic mechanical and viscoelastic properties of short hemp fibre polypropylene composites. Composites containing 10 to 60 wt.% short noil hemp fibre were injection moulded. The maleic anhydride grafted polypropylene (MAPP) and maleic anhydride grafted Poly(ethylene octane) (MAPOE) were used as coupling agents for modifying ...

A cocrystal strategy for the precipitation of liquid 2,3-dimethyl pyrazine with hydroxyl substituted benzoic acid and a Hirshfeld surfaces analysis of them
We here report the cocrystal strategy for the precipitation of liquid 2,3-dimethyl pyrazine (2,3-DMP) with the hydroxyl substituted benzoic acids: salicylic acid (SA), m-hydroxybenzoic acid (MHBA) and p-hydroxybenzoic acid (PHBA) under identical conditions, and obtained three cocrystals (cocrystal 1–3), respectively. Their crystal structures were characterized by single-crystal X-ray diffraction,...
