Marine Engineering Education For the 21St Century- Addressing the Oncoming Innovations in Ship Technology
(Lucian Blaga Univ Sibiu, Romania, 2009)A marine engineer, educated to work mainly on seagoing ships, has an expected professional life of about 40 years, both at sea and on shore facilities Therefore, the education he/she should have should address the expected ... -
Conceptual Study for a "Gas Hydrate Carrier Ship"
(World Scientific Publ Co Pte Ltd, 2009)The concept of transporting natural gas to distant overseas locations in the form of gas hydrates is discussed and a concept for ships for the carriage of unitized gas hydrate bulk cargo is introduced. The gas hydrate-carrying ... -
Modeling of Methane Distribution in a Landfill Using Genetic Algorithms
(Mary Ann Liebert, Inc, 2009)Landfill gas (LFG) results from the biologic decomposition of municipal waste and consists of mostly methane (CH4) and carbon dioxide (CO2), as well as trace amounts of a variety of other compounds. In this study, the major ... -
Dynamical instability of a boson-fermion mixture at low dimensions
(Elsevier Science Bv, 2009)We examine theoretically the dynamical response of a homogeneous mixture of condensed bosons and spin-polarized fermions confined inside a quasi-two-dimensional or a quasi-one-dimensional geometry, considering quasi-thre ... -
Development of standards for maritime english - the EU Leonardo martel project
(Dalian Maritime University Press, 2009)This paper reports on the progress of the EU funded Leonardo project MarTEL which concems the development of a set of standards for Maritime English for application in Merchant Navy education and training programmes for ... -
Does writing skills help students to overcome their shyness in oral performance?
(İstanbul Aydın Üniversitesi, 2009)This study prepared to see whether writing skills can help speaking or not. Many things interrupt people’s abilities in a negative way. These things can be named as internal and external factors such as; illnesses, atmosphere, ... -

Powering and seakeeping characteristics of a displacement hullform with waterline parabolization
(2010)Waterline parabolization is a design procedure used for displacement vessels to decrease the wave resistance of the hullform through the addition of amidships bulbs. The bow and shoulder wave system of a parent hullform ... -
Localization-delocalization transition in the random dimer model
(Amer Physical Soc, 2010)The random-dimer model is probably the most popular model for a one-dimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the ... -
Three-dimensional effects and arm effects on modeling a vertical axis tidal current turbine
(Pergamon-Elsevier Science Ltd, 2010)Three-dimensional effects in studying a vertical axis tidal current turbine are modeled using a newly developed vortex method. The effects on predicting power output and wake trajectory are analyzed in particular. The ... -
Modeling of twin-turbine systems with vertical axis tidal current turbines: Part I-Power output
(Pergamon-Elsevier Science Ltd, 2010)Recent interest in the tidal current industry has driven development of the prototype from the stand-alone turbine to the twin-turbine system. In this paper, we develop a numerical model to systematically analyze the ... -
Estimating Power Output from a Tidal Current Turbine Farm with First-order Approximation of Hydrodynamic Interaction between Turbines
(Taylor & Francis Inc, 2010)This article presents a numerical approach to estimate power output from a tidal current turbine farm with first-order approximation of hydrodynamic interactions between multiple turbines. An example study is conducted by ... -
A low cost alternative for satellites-tethered ultra-high altitude balloons
(2011)Geostationary and geosynchronous satellites have a wide area of application in present day technology. The main drawback for the wider usage of such satellites is their high cost of launching into their orbit. As alternatives ... -
Peripheral and Structural Effects on the Band Gap of Acceptor-Donor Type Conducting Polymers Containing Pendant Bisfulleroid Groups
(Amer Chemical Soc, 2011)In this computational study, the band gap energy of an acceptor donor type conducting polymer consisting of terthiophene repeating units with a fused bisfulleroid group was estimated by extrapolating excitation energies ... -
Second-order wave diffraction by horizontal rectangular barriers
(2011)A complete second-order analytical solution for the nonlinear diffraction of waves by 2-D rectangular cylinders fixed at the free surface of finite-depth waters is presented. As a sequel to a previous linear treatment of ... -
Condensation of two-dimensional harmonically confined bosons with Bessel-type interactions
(Amer Physical Soc, 2011)We study the ground-state configurations of few interacting bosons confined in two dimensions by anisotropic harmonic potentials. By means of variational calculations, including correlation effects, we show that the ... -
Anderson localization in optical lattices with speckle disorder
(Amer Physical Soc, 2011)We study the localization properties of noninteracting waves propagating in a speckle-like potential superposed on a one-dimensional lattice. Using a combined decimation-renormalization procedure, we estimate the localization ... -
