A novel OTA-based circuit model corroborated by an experimental semiconductor memristor
(Elsevier Science Bv, 2018)
A semiconductor memristor device based on a 300-nm ZnO thin film was fabricated by direct-current reactive sputter. The memristive behavior of this device was confirmed by time dependent current-voltage (I-V-t) measurements, ...
Multiobjective optimization of laminated composite cylindrical shells for maximum frequency and buckling load
(Elsevier Sci Ltd, 2009)
This paper deals with multiobjective optimization of laminated cylindrical shells to maximize a weighted sum of the frequency and buckling load under external load. The layer fibre orientation is used as the design variable ...
A Data-Driven Approach to Control Fugitive Dust in Mine Operations
(Springer Heidelberg, 2021)
Particulate matter (PM) is one of the main actors related to air pollution caused by surface mining. Fugitive dust, considered as particulate matter that cannot be collected by conventional measures, is classified by the ...
Effects of laminate carbon/epoxy composite patches on the strength of double-strap adhesive joints: Experimental and numerical analysis
(Elsevier Sci Ltd, 2013)
In this study, mechanical properties of double-strap joints with aluminum or composite patches of different orientation angles at their overlap area were investigated under tensile loading. For this purpose, AA2024-T3 ...
The Effect of Laughter Therapy on Anxiety A Meta-analysis
(Lippincott Williams & Wilkins, 2020)
This meta-analysis was conducted to determine the effect of laughter therapy on anxiety. Randomized controlled clinical trials were reviewed on Google Scholar, PubMed, and ISI Web of Sciences databases. Four randomized ...
Evaluation of potentially toxic element contents and Pb isotopic compositions in Ankara Stream sediments within an urban catchment in central Turkey
(Springer, 2017)
This study aimed to interpret the spatial distribution, enrichment factor (EF), and geo-accumulation of potentially toxic elements in the bed sediments (ASBS) and Pleistocene-aged overbank sediments (ASOS) of the Ankara ...
eNOS and iNOS trigger apoptosis in the brains of sheep and goats naturally infected with the border disease virus
(F Hernandez, 2015)
In this study, apoptotic and anti-apoptotic mechanisms and if present, which pathway to trigger the apoptosis in the brains of Border Disease Virus (BDV) infected lambs (n=10) and goat kids (n=5) were investigated. Briefly, ...
An assessment of machine learning models for slump flow and examining redundant features
(Techno-Press, 2020)
Over the years, several machine learning approaches have been proposed and utilized to create a prediction model for the high-performance concrete (HPC) slump flow. Despite HPC is a highly complex material, predicting its ...
Assessment of strength properties of cemented paste backfill by ultrasonic pulse velocity test
(Elsevier, 2014)
Ultrasonic pulse velocity (UPV) test is one of the most popular non-destructive techniques used in the assessment of the mechanical properties of concrete or rock materials. In this study, the effects of binder type/dosage, ...
Assessment of the concentration and environmental impacts of potential hazardous elements in coalfields in Northeastern Turkey
(Springer, 2021)
To investigate the impact of potential hazardous element (PHE) contamination on environmental and human health, the coaly shale, coal and shale coal outcrops of four sites, namely Ozyurt, Tarhanas, Kayadibi (Gumuhane), and ...
