An emission analysis study of hydrogen powered vehicles
(Pergamon-Elsevier Science Ltd, 2020)
In this study, emissions of internal combustion engine, hybrid, and fuel cell vehicles have been investigated when they use hydrogen in gas or liquid form. Well to pump (WTP) and well to wheel (WTW) emissions of volatile ...
Effects of acupressure, gum chewing and coffee consumption on the gastrointestinal system after caesarean section under spinal anaesthesia
(Taylor & Francis Inc, 2021)
This study evaluated the efficacy and safety of postoperative acupressure in the recovery of the gastrointestinal system (GIS) after caesarean section. A total of 160 primipara pregnant women delivered by caesarean section ...
Process damping model approach in milling operations
(Springer Heidelberg, 2021)
The subject of this study is a new Process Damping Model approach for milling with flat end milling cutter. Dynamic model of the cutting system was modeled and applied for the milling operation. The machining process is ...
RESEARCH ON TRIBOLOGICAL BEHAVIOR OF Cr3C2-25NiCr-COATED BRAKE DISC
(World Scientific Publ Co Pte Ltd, 2021)
This research presents the results of a comparative study to determine the friction and wear behavior of the high-velocity oxygen fuel (HVOF)-sprayed Cr3C2-25NiCr-coated brake disc. The friction and wear behavior of ...

A Novel ARMA Type Possibilistic Fuzzy Forecasting Functions Based on Grey-Wolf Optimizer (ARMA-PFFs)
(Springer, 2021)
This study proposes a new time series forecasting method that employs possibilistic fuzzy c-means, an autoregressive moving average model (ARMA), and a grey wolf optimizer (GWO) in type-1 fuzzy functions. Type-1 fuzzy ...
Effects of infill pattern and density on wear performance of FDM-printed acrylonitrile- butadiene-styrene parts
(Walter De Gruyter Gmbh, 2021)
Acrylonitrile-butadiene-styrene test specimens were additively manufactured by fused deposition method to investigate the effects of infill pattern and density on wear rate, coefficient of friction, wear mechanisms, and ...
