Unsupervised Machine Learning Identifies Shared Biomechanical and Clinical Variation in Individuals with Knee Osteoarthritis and High Body Mass Index

Arthritis Care &Research, EarlyView.
Objective High body mass index (BMI ≥ 27 kg/m2) and aberrant gait biomechanics are primary risk factors for knee osteoarthritis (KOA), yet the specific loading patterns linked to clinical disease features remain unclear. Unsupervised machine learning (ML) was used to identify vertical ground reaction force (vGRF) waveform modes of variation and ...

NEW THIO S2- ADDUCTS WITH ANTIMONY (III AND V) HALIDE: SYNTHESIS AND INFRARED STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2013
Five new S2- adducts with SbIII and SbV halides have been synthesized and studied by infrared. Discrete structures have been suggested, the environment around the antimony being tetrahedral, trigonal bipyramidal or octahedral.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

NEW TIN (IV), MX2 AND M’Cl3 (M= Zn, Hg; M’= Pr, Er) ADDUCTS AND COMPLEXES OF BIS(AMINOMETHYLBENZENE): SYNTHESIS AND INFRARED STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2015
The new adducts and complexes obtained have discrete or dimeric structures; in these structures the diamine behaves as a monodentate and hydrogen bonds involved or bidentate ligand.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

SOME SULFATO ADDUCTS AND DERIVATIVE: SYNTHESIS AND SPECTROSCOPIC STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
Three new adducts and derivative have been synthesized and studied by infrared and NMR spectroscopies. The suggested structures are discrete with a sulfate behaving as a monochelating, bichelating or monodentate ligand, the environments around the tin ...

Discrete Sizing Optimization of Steel Structures Using Modified Fireworks Algorithm [PDF]

Journal of Soft Computing in Civil Engineering
Fireworks algorithm (FWA) is an artificial intelligence algorithm developed by emulating the burst process of fireworks. This paper applies a modified version of fireworks algorithm called MoFWA to design disparate steel trusses and planar frames.
