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 hydratecarrying ... 
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 bosonfermion mixture at low dimensions
(Elsevier Science Bv, 2009)We examine theoretically the dynamical response of a homogeneous mixture of condensed bosons and spinpolarized fermions confined inside a quasitwodimensional or a quasionedimensional geometry, considering quasithre ... 
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 ... 
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 ... 
Localizationdelocalization transition in the random dimer model
(Amer Physical Soc, 2010)The randomdimer model is probably the most popular model for a onedimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the ... 
Threedimensional effects and arm effects on modeling a vertical axis tidal current turbine
(PergamonElsevier Science Ltd, 2010)Threedimensional 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 twinturbine systems with vertical axis tidal current turbines: Part IPower output
(PergamonElsevier Science Ltd, 2010)Recent interest in the tidal current industry has driven development of the prototype from the standalone turbine to the twinturbine system. In this paper, we develop a numerical model to systematically analyze the ... 
Estimating Power Output from a Tidal Current Turbine Farm with Firstorder 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 firstorder approximation of hydrodynamic interactions between multiple turbines. An example study is conducted by ... 
A low cost alternative for satellitestethered ultrahigh 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 AcceptorDonor 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 ... 
Secondorder wave diffraction by horizontal rectangular barriers
