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 ... -
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 ... -

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
