Assessment of thermodynamics performance with sustainable propulsion indicators of a seaplane engine for different temperatures in the same altitude
(Taylor & Francis Inc, 2017)
Seaplanes have become an important tool along with rapidly developing technology in modern transportation for many countries related to sea. Considering the environmental evaluation for these aircraft, decreasing fossil ...
Detection of Nitroaromatic Explosives Based on Fluorescence Quenching of Silafluorene- and Silole-Containing Polymers: A Time-Dependent Density Functional Theory Study
(Amer Chemical Soc, 2014)
Poly(silafluorene-phenylenedivinylene)s and poly((tetraphenyl)-silole- phenylenedivinylene)s are promising materials to be used as chemical sensors for explosives detection. The optoelectronic properties of these polymers ...
The effect of pattern sizes on oleophobicity and superhydrophobicity of micropatterned surfaces
(Elsevier Science Sa, 2016)
In this study, cylindrical pillars with varying diameters between 10 mu m to 100 mu m, seperation distances between 5 mu m to 10 mu m, constant heights of 40 mu m +/- 2 and solid area fractions [f(s)(CB) (geo)] between ...
The effect of perfluoroalkyl and hydrocarbon liquid chain lengths on oleophobic behaviors of copolymer surfaces
(Elsevier Science Bv, 2014)
In this work, the effect of wt.% of perfluoroalkyl content and also hydrocarbon chain length on oleophobic properties of perfluoroethyl alkyl methacrylate-methyl methacrylate (Zonyl-TM-MMA) copolymers was investigated. The ...

In sea transport having dynamic conditions, for all energy consuming equipment's of ships, effective and efficient use of energy is important to ensure. In this study, the thermodynamics performance effect related to cooling ...
Static and dynamic structure of monomers, dimers and trimers of HgCl2 from density-functional calculations
(Springer, 2012)
We report relativistic density-functional calculations for the equilibrium structures and the vibrational frequencies of the (HgCl2)(n) molecules with n = 1 to 3, as part of a broad exploration of the potential energy ...
Application of Fuzzy Fault Tree Analysis (FFTA) to maritime industry: A risk analysing of ship mooring operation
(Pergamon-Elsevier Science Ltd, 2019)
Risk assessment has always been a serious concern in maritime transportation since shipping activities can pose potential harm to human life, commodity and maritime environment. Maritime safety researchers, in this context, ...
Chemical Reactivity Perspective into the Group 2B Metals Halides
(Amer Chemical Soc, 2016)
Chemical reactivity descriptors within the conceptual density functional theory can be used to understand the nature of the interactions between two monomers of the Group 2B metal halides. This information might be valuable ...
Application of human reliability analysis to repair & maintenance operations on-board ships: the case of HFO purifier overhauling
(Elsevier Sci Ltd, 2019)
Maintenance and repair at the operational level is a critical function to comply with the standard of competence for officers in charge of an engineering watch in a manned/unmanned ship engine room. The human factor in ...
