Impact of Wall Impedance Phase Angle on Indoor Sound Field and Reverberation Parameters Derived from Room Impulse Response [PDF]
Archives of Acoustics, 2022 Accurate definition of boundary conditions is of crucial importance for room acoustic predictions because the wall impedance phase angle can affect the sound field in rooms and acoustic parameters applied to assess a room reverberation.

Insights on Oscillations and Impulses in Variable Impedance Control
, 2022 Operational-space impedance control allows to assign a mass-damper-spring (MDS) behavior to the end effector of a robotic manipulator. This aids resilience when interactions with the environment or humans are expected. While changing the virtual mass is not always practicable since it requires using precise force/torque sensors, varying the stiffness ...

A Study on Frequency Response Functions in Pavement Engineering
The Baltic Journal of Road and Bridge Engineering, 2023 Mechanical impedance (MI) defines the ability of a system to vibrate as a consequence of force application. In the recent years, the correlation of this parameter with tire-road noise and other characteristics has gained certain attention.

Stability, Causality, and Passivity in Electrical Interconnect Models [PDF]
, 2007 Modern packaging design requires extensive signal integrity simulations in order to assess the electrical performance of the system. The feasibility of such simulations is granted only when accurate and efficient models are available for all system parts

Parameter Estimation of a Grid-Tied Inverter Using In Situ Pseudo-Random Perturbation Sources
Energies, 2023 Inverters are playing an increasingly important role in the electrical utility grid due to the proliferation of renewable energy sources. Obtaining inverter models with accurate parameters is, therefore, essential for grid studies and design.

Time-Response Functions of Mechanical Networks with Inerters and Causality
, 2017 This paper derives the causal time-response functions of three-parameter mechanical networks that have been reported in the literature and involve the inerter-a two-node element in which the force-output is proportional to the relative acceleration of ...

Hypervelocity Richtmyer–Meshkov instability [PDF]
, 1997 The Richtmyer-Meshkov instability is numerically investigated for strong shocks, i.e., for hypervelocity cases. To model the interaction of the flow with non-equilibrium chemical effects typical of high-enthalpy flows, the Lighthill-Freeman ideal ...
