Higgs mechanism and the added-mass effect. [PDF]

open access: yesProc Math Phys Eng Sci, 2015
In the Higgs mechanism, mediators of the weak force acquire masses by interacting with the Higgs condensate, leading to a vector boson mass matrix. On the other hand, a rigid body accelerated through an inviscid, incompressible and irrotational fluid feels an opposing force linearly related to its acceleration, via an added-mass tensor.

How Does Added Mass Affect the Gait of Middle-Aged Adults? An Assessment Using Statistical Parametric Mapping [PDF]

open access: yesSensors, 2022
To improve exoskeleton designs, it is crucial to understand the effects of the placement of such added mass on a broad spectrum of users. Most prior studies on the effects of added mass on gait have analyzed young adults using discrete point analysis ...

Ankle and midtarsal joint quasi-stiffness during walking with added mass [PDF]

open access: yesPeerJ, 2019
Examination of how the ankle and midtarsal joints modulate stiffness in response to increased force demand will aid understanding of overall limb function and inform the development of bio-inspired assistive and robotic devices. The purpose of this study

Numerical Simulation and Analysis of Added Mass for the Underwater Variable Speed Motion of Small Objects

open access: yesJournal of Marine Science and Engineering
Unlike uniform motion, when an object moves underwater with variable speed, it experiences additional resistance from the water, commonly referred to as added mass force.

Conformal mass in AdS gravity [PDF]

open access: yesPhysical Review D, 2014
We show that the Ashtekar-Magnon-Das (AMD) mass and other conserved quantities are equivalent to the Kounterterm charges in the asymptotically AdS spacetimes that satisfy the Einstein equations, if we assume the same asymptotic fall-off behavior of the Weyl tensor as considered by AMD.

The Radiation Problem of a Submerged Oblate Spheroid in Finite Water Depth Using the Method of the Image Singularities System

open access: yesFluids, 2022
This study examines the hydrodynamic parameters of a unique geometry that could be used effectively for wave energy extraction applications. In particular, we are concerned with the oblate spheroidal geometry that provides the advantage of a wider impact

A Modified Wake Oscillator Model for the Cross-Flow Vortex-Induced Vibration of Rigid Cylinders with Low Mass and Damping Ratios

open access: yesJournal of Marine Science and Engineering, 2023
The classical wake oscillator model is capable of predicting the vortex-induced vibration response of a cylinder at high mass-damping ratios, but it fails to perform satisfactorily at low mass-damping ratios. A modified wake oscillator model is presented

An Experimental Assessment of Unsteady Forces on a Plunging Airfoil Oscillating in Stationary Fluid at High Frequencies [PDF]

open access: yesJournal of Engineering Science and Military Technologies, 2017
Experiments were conducted to measure the unsteady plunging forces on a NACA- 0012 airfoil at zero undisturbed flow velocity. The aim is to investigate the vari- ation of the added forces associated with high oscillation frequencies at various angles of ...

Computation of the Added Masses of an Unconventional Airship [PDF]

open access: yesJournal of Applied Mathematics, 2012
This paper presents a modelling of an unmanned airship. We are studying a quadrotor flying wing. The modelling of this airship includes an aerodynamic study. A special focus is done on the computation of the added masses. Considering that the velocity potential of the air surrounding the airship obeys the Laplace′s equation, the added masses matrix ...
