The Output Effect of Stopping Inflation when Velocity is Time Varying [PDF]
SSRN Electronic Journal, 2007 This paper explores the effect of time varying velocity in a transition to price stability. Nonstationary velocity, expressed as function of consumption, is made endogenous in Ireland’s (1997) model. We find that the ‘disinflationary booms’ found by Ball (1994) may or may not disappear; and also that temporary output losses may be much larger than

Impact-Time-Control Guidance Law for Missile with Time-Varying Velocity [PDF]
Mathematical Problems in Engineering, 2016 The problem of impact-time-control guidance (ITCG) for the homing missile with time-varying velocity is addressed. First, a novel ITCG law is proposed based on the integral sliding mode control (ISMC) method. Then, a salvo attack algorithm is designed based on the proposed guidance law.

Precise impact time and angle guidance strategy under time-varying velocity
Nonlinear Dynamics, 2023 Abstract In this paper, a new guidance strategy is proposed for achieving precise control of time-varying velocity aircraft with impact time and angle constraints. Traditional guidance laws assume a constant velocity of the aircraft, but the velocity varies with time in practical scenarios, which affects the guidance accuracy under impact time ...

Numerical integration of the contravariant integral form of the Navier–Stokes equations in time-dependent curvilinear coordinate systems for three-dimensional free surface flows [PDF]
, 2019 We propose a three-dimensional non-hydrostatic shock-capturing numerical model for the simulation of wave propagation, transformation and breaking, which is based on an original integral formulation of the contravariant Navier–Stokes equations, devoid of

Spacecraft formation-containment flying control with time-varying translational velocity
Chinese Journal of Aeronautics, 2020 Abstract This paper investigates the problem of Spacecraft Formation-Containment Flying Control (SFCFC) when the desired translational velocity is time-varying. In SFCFC problem, there are multiple leader spacecraft and multiple follower spacecraft and SFCFC can be divided into leader spacecraft’s formation control and follower spacecraft’s ...

Velocity profile method for time varying resistance in minimal cardiovascular system models [PDF]
Physics in Medicine and Biology, 2003 This paper investigates the fluid dynamics governing arterial flow used in lumped parameter cardiovascular system (CVS) models, particularly near the heart where arteries are large. Assumptions made in applying equations conventionally used in lumped parameter models are investigated, specifically that of constant resistance to flow.

Local stable and unstable manifolds and their control in nonautonomous finite-time flows [PDF]
, 2016 It is well-known that stable and unstable manifolds strongly influence fluid motion in unsteady flows. These emanate from hyperbolic trajectories, with the structures moving nonautonomously in time.

Method for estimating pulsatile wall shear stress from one‐dimensional velocity waveforms
Physiological Reports, 2023 Wall shear stress (WSS)—a key regulator of endothelial function—is commonly estimated in vivo using simplified mathematical models based on Poiseuille's flow, assuming a quasi‐steady parabolic velocity distribution, despite evidence that more rapidly ...
