Digital image processing of warm mix asphalt enriched with nanocolemanite and nanoulexite minerals
(Elsevier, 2023)Digital image processing (DIP) is a method used to view the internal structure of hot mix asphalt. However, in this study, the DIP of warm mix asphalt (WMA), which reduces environmental emissions and saves energy, was been ... -
Control of dynamic trim for planing vessels with interceptors in terms of comfort and minimum drag
(2023)Nowadays, interceptors are often used to decrease total resistance and enhance comfort by reducing dynamic trim for high-speed planing vessels. They can be controlled manually as well as automatically by using a suitable ... -
Population dynamics of deep-water pink shrimp (Parapenaeus longirostris Lucas, 1846) (Decapoda, Penaeidae) in the coastal waters of Tuzla (Eastern part of the Sea of Marmara)
(ScientificWebJournals (SWJ), 2022)In this study, the population parameters, recruitment period, exploitation rate, and stock status of deepwater pink shrimp (Parapenaeus longirostris Lucas, 1846) in the eastern Sea of Marmara were investigated. Growth ... -
Active control of vertical acceleration with T-Foil and trim tab systems in a fast ferry
(Dokuz Eylul University, 2022)his study is concerned with the active T-foil placed near the bow on the keel line of the fast ferry and two active trim tab controls placed at the stern to improve the maritime performance of a fast ferry, whilst improving ... -

(Gümüşhane Üniversitesi, 2021)Kolemanit minerali (C-3 mm) ve öğütülmüş kolemanit mineralleri (C-75 µm ile C-45 µm tozları) Eti Maden Bigadiç Bor İşletme Müdürlüğünden tedarik edildi. C-3 mm başlangıç malzemesi yüksek enerjili bilyalı değirmende öğütme ... -
An extended human reliability analysing under fuzzy logic environment for ship navigation
(Taylor & Francis Ltd., 2022)Preparation for a sea voyage is one of the fundamental aspects of navigation. Several complexities are involved during the preparation of the ship for navigation due to the nature of maritime work. At this point, analysing ... -
Prediction of human–machine interface (HMI) operational errors for maritime autonomous surface ships (MASS)
(Springer, 2022)The human factor is a hot topic for the maritime industry since more than 80 percent of maritime accidents are due to human error. Minimizing human error contributions in maritime transportation is vital to enhance safety ... -
Numerical risk analysis of gas freeing process in oil/chemical tanker ships
(Elsevier, 2022)Gas freeing is one of the most hazardous and critical operations on oil/chemical tankers. The process aims to remove toxic gases from tanks and bring oxygen to a healthy level (21%) in the tank atmosphere. Significant ... -
Assessment of human error contribution to maritime pilot transfer operation under HFACS-PV and SLIM approach
(Elsevier, 2022)Human factor plays an important role in sustainable maritime transportation. Human errors are the leading cause of death or injuries during maritime pilot transfer operations despite international regulations. This paper ... -
Numerical evaluation on the effects of interceptor layout and blade heights for a prismatic planing hull
(Elsevier, 2022)Planing hulls are exposed to effects such as trim and resistance that have a negative impact on their hydrodynamic performances. Interceptors are one of the systems to find solutions to reduce these negative effects. In ... -
