Farklı bor kimyasalları ile borlanmış Inconel 625 alaşımının karakterizasyonu
(Pamukkale Üniversitesi Mühendislik Bilimleri Dergisi, 2017)
Bu çalışmada, nikel bazlı süper alaşımlar içerisinde endüstride yaygın olarak kullanılan Inconel 625 alaşımı 3 farklı borlama tozu ile borlanmıştır. Kullanılan borlama tozları, %90 elementel nano bor tozu + %10 NaBF4 (NB), ...
Experimental investigation on cyclic variability, engine performance, and exhaust emissions in a diesel engine using alcohol-diesel fuel blends
(Serbian Society of Heat Transfer Engineers, 2017)
This paper investigates the impacts of using n-butanol-diesel fuel and ethanol-diesel fuel blends on engine performance, exhaust emission, and cycle-by-cycle variation in a Diesel engine. The engine was operated at two ...
A new method for calculating fuel consumption and displacement of a ship in maritime transport
(Taylor & Francis AS, 2017)
Fuel consumption is the most important parameter which is effected by the petrol prices. Optimization of the sailing speed decreases the fuel cost because it is proportional to the sailing speed. In this study, the present ...
A novel fuzzy logic based safe operation oriented control technique for driving HHO dry cell systems based on PWM duty cycle
(Elsevier, 2019)
The presented study provides details on Fuzzy Logic based control of HHO generators aims at protecting the HHO generator from extreme temperature effects while maximizing the hydrogen production. The Fuzzy Logic Controller ...
Changes in digestive enzyme activities during different developmental stages of the crayfish Astacus leptodactylus Eschscholtz, 1823
(Indian Council of Agricultural Research, 2018)
The present study determined changes in protease, alpha-amylase and lipase activities during embryonic and post-embryonic developmental stages of the freshwater crayfish Astacus leptodactylus Eschscholtz, 1823. The embryonic ...
Review of heavy metal accumulation on aquatic environment in Northern East Mediterrenean Sea part I: some essential metals
(Walter de Gruyter GmbH, 2017)
All pollutants can reach the aquatic environments and the levels of heavy metals in upper members of the food web like fish can reach values many times higher than those found in aquatic environment or in sediments. Although ...
Deep learning with 3D-second order difference plot on respiratory sounds
(Elsevier, 2018)
The second order difference plot (SODP) is a nonlinear signal analysis method that visualizes two consecutive data points for many types of biomedical signals. The proposed method is based on analysing quantization of ...
Comparison of stable isotope values of Quaternary calcretes from Adana and Mersin provinces: implications on controlling factors
(Scientific Technical Research Council Turkey-Tubitak, 2019)
Calcretes are widespread in Adana and Mersin provinces and form under different morphologies. Most calcrete profiles comprise a hard laminated crust/hardpan at the top, gradually intergrading into the nodular and/or ...
Solar energy harvesting with ultra-broadband metamaterial absorber
(World Scientific Publishing Co. Pte Ltd, 2019)
In this study, a novel metamaterial absorber (MA) is designed and numerically demonstrated for solar energy harvesting. The structure is composed of three layers with different thicknesses. The interactions of three layers ...
