The Added Resistance of Ships in Regular Oblique Waves
Journal of the Society of Naval Architects of Japan, 1973 A method for calculating the added resistance of ships in regular oblique waves was developed, based upon Maruo's theory. It is assumed that the velocity potential of fluid motions around the ship's hull is obtained from the conception of strip method.

Influence of Bow Flare Shapes on Added Resistance in Waves
Journal of the Japan Society of Naval Architects and Ocean Engineers, 2010 Added resistance in waves is a predominant component for the estimation of ship speed in actual seas, so that it is necessary to be calculated accurately. The added resistance in waves is influenced by the hull form above water line. However it is difficult to take into consideration the form to the calculation theoretically.

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework
Advanced Functional Materials, EarlyView.The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Influence of the approximated mass characteristics of a ship on the added resistance in waves
, 2017 Dodatni otpor na valovima važno je predvidjeti već u ranoj fazi projektiranja broda. Povećanje otpora uzrokovano valovima utječe na brzinu broda i potrošnju goriva te može predstavljati značajan problem s aspekta očuvanja okoliša.

Advanced Functional Materials, EarlyView.Moiré band engineering in graphene/hexagonal boron nitride–based superlattices unlocks van Hove singularities (VHSs) for terahertz (THz) optoelectronics. Tuning the Fermi level near these singularities, associated with secondary neutrality points (SNPs), enhances the photothermoelectric response.

A Novel Measure to Reduce Ship Resistance in Waves
, 2017 Ships travel in waves most of the time. The horsepower increase or speed loss in waves can become large in adverse sea. Speed loss needs to be compensated for by increasing the power.
