Gradient boosting for Parkinson's disease diagnosis from voice recordings
(Bmc, 2020)
Background Parkinson's Disease (PD) is a clinically diagnosed neurodegenerative disorder that affects both motor and non-motor neural circuits. Speech deterioration (hypokinetic dysarthria) is a common symptom, which often ...
Some integral inequalities of Hermite-Hadamard type for multiplicatively preinvex functions
(Amer Inst Mathematical Sciences-Aims, 2020)
In this paper, some integral inequalities of Hermite-Hadamard type for multiplicatively preinvex functions are established. Also, new inequalities involving multiplicative integrals are obtained for product and quotient ...
The effects of STEM activities on the problem-solving skills of 6-year-old preschool children
(Routledge Journals, Taylor & Francis Ltd, 2021)
In this study, the effects of STEM activities on the problem-solving skills of preschool children were investigated. A two-group (study: n = 18 and control: n = 18) pre-test/post-test/retention test experimental design was ...
Synthesis and characterization of metallo phthalocyanines bearing 7-oxy-3-(4-pyridyl)coumarin substituents and their supramolecular structures with vanadyl bis(acetylacetonate)
(Pergamon-Elsevier Science Ltd, 2012)
The synthesis of novel zinc and cobalt metallo phthalocyanines with four 7-oxy-3-(4-pyridyl)coumarin dye groups on the periphery/non-periphery were prepared by cyclotetramerization of 7-(3,4-dicyanophenoxy)-3-(4-pyridyl)coumarin ...
Examination of the temperature related structural defects of InGaN/GaN solar cells
(Academic Press Ltd- Elsevier Science Ltd, 2015)
In this study the effects of the annealing temperature on the InGaN/GaN solar cells with different In-contents grown on sapphire substrate by the Metal Organic Chemical Vapor Deposition (MOCVD) are analyzed by High Resolution ...
The Effects of Different Grain Brans Used as Substrates on Resistance to Catabolite Repression in Solid-State Fermentation Process
(Chem Soc Pakistan, 2014)
Production of alpha-amylase from Penicillium brevicompactum was investigated in solid-state fermentation (SSF) using as substrate wheat bran (WB), rye bran (RB) and barley bran (BB) enriched with different amount of glucose ...
FFANN Optimization by ABC for Controlling a 2nd Order SISO System's Output with a Desired Settling Time
(Mdpi, 2019)
In this study, a control strategy is aimed to ensure the settling time of a 2nd order system's output value while its input reference value is changed. Here, Feed Forward Artificial Neural Network (FFANN) nonlinear structure ...
Heat transfer of brake pad used in the autos after friction and examination of thermal tension analysis
(2014)
As a result of the friction of brake pads which is one of the factors affecting automobile performances with brake disc, heat energy comes into being. This heat energy causes brake pads to expose to excessive temperature. ...
How liquid hydrogen production methods affect emissions in liquid hydrogen powered vehicles?
(Pergamon-Elsevier Science Ltd, 2020)
Emissions variations of liquid hydrogen (LH2) production methods in liquid hydrogen powered vehicles are investigated in this study. Volatile organic compounds (VOC), carbon monoxide (CO), nitrogen oxides (NOx), particulate ...
