A numerical study on squat of a wigley hull
(2011)A numerical study is conducted to calculate the squat for a wigley hull. An approach based on slender body theory is used to convert the three dimensional ship problem into a series of two dimensional problems in cross ... -
An integrated model for estimating energy cost of a tidal current turbine farm
(Pergamon-Elsevier Science Ltd, 2011)A tidal current turbine is a device for harnessing energy from tidal currents and functions in a manner similar to a wind turbine. A tidal current turbine farm consists of a group of tidal current turbines distributed in ... -
Investigation of thermal effects and physical parameters on crosslinking by different riboflavin solutions and UV-A
(2012)Riboflavin-Dextran and Riboflavin-Dextrin solutions have the ability to create crosslinks between fibrilles in the biological tissues. These solutions cause the generation of free oxygen radicals by the excitement of UV ... -
Thermal effects on cornea during keratoconus treatment
(2012)Keratoconus is characterized by stromal thinning that leads to corneal surface distortion. It causes nanofibrils become weaker and change in cornea's shape. Cornea leans out. Symptoms such as astigmatism appeared as a ... -
Comparison of two base-potentials for a slender-body method
(2012)The effects of two base-potentials on the accuracy of a slender-body method are studied in this paper. In the formulation for this method which is developed for the slender ships, the velocity potential is decomposed into ... -
Environmental fatigue behavior of non-crimp, E-glass fiber reinforced polyester composites for marine applications
(Wiley-V C H Verlag Gmbh, 2012)This study is aimed to find the fatigue behavior of Glass Reinforced Plastics, a material which is a widely preferred material for small marine crafts, as well as several other applications. The type of composite tested ... -
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 ... -
Monitoring the gelation of polyacrylamide-sodium alginate composite by fluorescence technique
(Taylor & Francis Ltd, 2012)Polyacrylamide (PAAm)-sodium alginate (SA) composite was prepared with different amounts of SA varying in the range between 0.06% and 2% (w/v). The PAAm-SA composite was characterized by the steady-state fluorescence ... -
Elastic percolation of swollen polyacrylamide (PAAm)-multiwall carbon nanotubes composite
(Taylor & Francis Ltd, 2012)Polyacrylamide (PAAm)-multiwalled carbon nanotube (MWNT) composites were prepared via free radical cross-linking copolymerization with different amounts of MWNTs varying in the range between 0.1 and 50 wt%. The mechanical ... -
PAAm-Kappa Carrageenan Composites: Drying and Swelling with Various Kappa Carrageenan Contents
(Polish Acad Sciences Inst Physics, 2012)The purpose of this study is to discuss the role of kappa-carrageenan (kappa-car) in the drying and swelling of polyacrylamide (PAAm)-kappa-car composite. The fluorescence intensity of pyranine increased and decreased as ... -
Monitoring of dynamical processes in PAAm-MWNTs composites by fluorescence method
(Taylor & Francis Ltd, 2012)Polyacrylamide (PAAm)-multi walled carbon nanotube (MWNT) composites were prepared by free radical cross-linking copolymerization in water. Ammonium persulfate and N,N'-methylenebis (acrylamide) (BIS) were used as a free ... -
Adaptive Multichannel Sequential Lattice Prediction Filtering Method For Cognitive Radio Spectrum Sensing in Subbands
(IEEE, 2012)A multichannel characterization for autoregressive moving average(ARMA) spectrum estimation in subbands with applications to cognitive radio spectrum sensing is considered in this presentation. The fullband ARMA spectrum ... -
Piecemeal approach to development of STCW and the consequences - A case for comprehensive review of the current maritime education and training standards
(2012)A review of a recent research has shown that 25% of the world fleet are responsible for more than 50% of shipping accidents, while the top 25% of the safest ships caused just 7% of all accidents. Another study has reported ... -
