A coupled parametric and nonparametric approach for modal analysis of a satellite [PDF]

, 2013
This study takes place in the context of dynamical prediction for satellite structures. Aims of such studies are to survey the dynamical response of satellite equipment and components, to check that requirements are correct and to give prediction of ...

Improving a joint inversion of GRACE, GPS and modelled ocean bottom pressure by using in-situ data. [PDF]

, 2012
To investigate the changes in ocean bottom pressure (OBP) and ocean mass Rietbroek et al. (2009) performed a joint least square inversion of weekly GRACE solutions, patterns of large-scale deformation measured by a network of GPS stations and modelled ...

A study of O/X wave data assimilation and inversion for ionospheric vertical electron density profiles

Frontiers in Astronomy and Space Sciences
Vertical sounding of the ionosphere yields ionograms that reflects the relationship between virtual height and frequency, and electron density profiles can be obtained by inversion of the ionogram.

Recursive mass matrix factorization and inversion: An operator approach to open- and closed-chain multibody dynamics [PDF]

This report advances a linear operator approach for analyzing the dynamics of systems of joint-connected rigid bodies.It is established that the mass matrix M for such a system can be factored as M=(I+H phi L)D(I+H phi L) sup T.

The Efficacy of Anterior Cruciate Ligament Reconstruction with Peroneus Longus Tendon and its Impact on Ankle Joint Function

Orthopaedic Surgery
Objective Peroneus Longus Tendon (PLT), a viable anterior cruciate ligament (ACL) graft, shares similar biomechanics, making it suitable for reconstruction. Controversy exists over whether PLT transplants affects the donor ankle joint.

The 2023 Mw 6.8 Adassil Earthquake (Chichaoua, Morocco) on a steep reverse fault in the deep crust and its geodynamic implications

Earth and Planetary Physics
The Mw 6.8 Adassil earthquake that occurred in the High Atlas on September 8, 2023, was a catastrophic event that provided a rare opportunity to study the mechanics of deep crustal seismicity.

A "One-line" Simulator for Maxima or Minima on Drifting Brownian Paths [PDF]

A simple transform of a standard uniform variate is given for simulation of the maximum attained by a Wiener process with drift, conditioned upon the level attained by the process over an arbitrary time interval.
