Development of Magnetostrictive Transducer Prototype for Blockage Detection on Molten Salt Pipes [PDF]

open access: yes, 2018
In solar thermal power plants molten salt is often used to store and transport the energy that is collected during the day. The external pipe temperature is measured to activate an electric heating system if the temperature approaches the melting point ...

Numerical investigation of added resistance of a container ship in short regular waves using unsteady RANS simulations

open access: yesBrodogradnja
Accurately predicting the added resistance coefficient in short waves remains a challenge. This study aims to investigate the added resistance of a container ship in regular short-head waves at moderate Froude numbers through unsteady RANS simulations. A

Bow hull-form optimization in waves of a 66,000 DWT bulk carrier

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
This paper uses optimization techniques to obtain bow hull form of a 66,000 DWT bulk carrier in calm water and in waves. Parametric modification functions of SAC and section shape of DLWL are used for hull form variation.

Synapse elimination and learning rules co-regulated by MHC class I H2-Db. [PDF]

open access: yes, 2014
The formation of precise connections between retina and lateral geniculate nucleus (LGN) involves the activity-dependent elimination of some synapses, with strengthening and retention of others. Here we show that the major histocompatibility complex (MHC)

Swimming Speeds of Waving Cylindrical Tails in Viscous Fluids with Resistance

open access: yes, 2015
Many microorganisms swim in a highly heterogeneous environment with obstacles such as fibers or polymers. To better understand how this environment affects microorganism swimming, we study propulsion of a cylinder or filament in a fluid with a sparse ...

THz in biology and medicine: toward quantifying and understanding the interaction of millimeter- and submillimeter-waves with cells and cell processes [PDF]

open access: yes, 2010
As the application and commercial use of millimeter- and submillimeter-wavelength radiation become more widespread, there is a growing need to understand and quantify both the coupling mechanisms and the impact of this long wavelength energy on ...

Perfect absorption of water waves by linear or nonlinear critical coupling

open access: yes, 2018
We report on experiments of perfect absorption for surface gravity waves impinging a wall structured by a subwavelength resonator. By tuning the geometry of the resonator, a balance is achieved between the radiation damping and the intrinsic viscous ...

Millimeter-wave diode-grid phase shifters [PDF]

open access: yes, 1988
Monolithic diode grids have been fabricated on 2-cm square gallium-arsenide wafers with 1600 Schottky-barrier varactor diodes. Shorted diodes are detected with a liquid-crystal technique, and the bad diodes are removed with an ultrasonic probe.

CFD computation of ship motions and added resistance for a high speed trimaran in regular head waves

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2011
Some research work on CFD computation of ship motions and added resistance in waves for a high speed trimaran is carried out in this paper. The governing equations, Reynolds Averaged Navier-Stokes and continuity equations are discretized by finite volume
