Embedded atom method-based geometry optimization aspects of body-centered cubic metals
(2013)
We present embedded atom method-based geometry optimization calculations for Fe, Cr, Mo, Nb, Ta, V and W body-centered cubic metals with Finnis - Sinclair potentials. After the optimization, we determine their typical ...
Wet electrospun silk fibroin/gold nanoparticle 3D matrices for wound healing applications
(Royal Society of Chemistry, 2016)
This study aimed to fabricate 3D silk fibroin (SF) matrices for skin tissue engineering applications. SF/poly(ethylene oxide) solutions were wet electrospun to obtain a fibrous network (0.7–20 μm diameter), which were then ...
The thermodynamic stability of intermediate solid solutions in LiFePO4 nanoparticles
(Royal Society of Chemistry, 2016)
Theoretical predictions from first principles and recent advances in in situ electrochemical characterization techniques have confirmed the presence of solid-solution states during electrochemical (de)lithiation of LiFePO4 ...
Particle-size and morphology dependence of the preferred interface orientation in LiFePO4 nano-particles
(Royal Society of Chemistry, 2014)
We gain new insights into the equilibrium properties and potential two-phase lithiation mechanisms in LiFePO4 nano-particles by conducting a first-principles investigation of the anisotropic chemical interfacial energy ...
Modified ultrasound despeckling assessment index for the Field II simulated cyst image
(Institution of Engineering and Technology, 2017)
Various methods have been proposed to reduce speckle noise, which decreases image quality in ultrasound images. The Field II simulated cyst image consists of three classes and is used to compare a proposed despeckle filter ...
A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins
(Nature Publishing Groups, 2018)
Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ...
Diagnostic value of copeptin in acute myocardial infarction
(2017)
PATIENTS AND METHODS: A total of 160 cases were enrolled in the study. All were over 18 years of age, and consisted of 54 non-ST elevation MI (NSTEMI), 54 ST segment elevation MI (STEMI), and 52 healthy subjects (controls). ...
An ARMA type fuzzy time series forecasting method based on particle swarm optimization
(2013)
In the literature, fuzzy time series forecasting models generally include fuzzy lagged variables. Thus, these fuzzy time series models have only autoregressive structure. Using such fuzzy time series models can cause ...
A new high order fuzzy ARMA time series forecasting method by using neural networks to define fuzzy relations
(Hindawi Publishing Corporation, 2015)
Linear time series methods are researched under 3 topics, namely, AR (autoregressive), MA (moving averages), and ARMA (autoregressive moving averages) models. On the other hand, the univariate fuzzy time series forecasting ...
First-order ARMA type fuzzy time series method based on fuzzy logic relation tables
(2013)
Fuzzy time series approaches have an important deficiency according to classical time series approaches. This deficiency comes from the fact that all of the fuzzy time series models developed in the literature use ...
