Computing the Rank Profile Matrix [PDF]

, 2015
The row (resp. column) rank profile of a matrix describes the staircase shape of its row (resp. column) echelon form. In an ISSAC'13 paper, we proposed a recursive Gaussian elimination that can compute simultaneously the row and column rank profiles of a

Seismic Assessment Procedure for Exterior Reinforced Concrete Beam–Column Joints With Slab and Transverse Beams

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Pilot Experimental Tests on Punching Shear Strength of Flat Plates Reinforced with Stirrups Punching Shear Reinforcement [PDF]

, 2017
Flat plates are favor structure systems usually used in parking garages and high-rise buildings due to its simplicity for construction. However, flat plates have some inherent structural problems, due to high shear stress surrounding the supporting ...

A General Framework for Knowledge Integration in Machine Learning for Electromagnetic Scattering Using Quasinormal Modes

Laser &Photonics Reviews, EarlyView.
Neural networks can accelerate modeling and inverse design of electromagnetic devices by several orders of magnitude, but usually require large amounts of data to train. This work demonstrates that integrating knowledge about quasinormal modes into the network architecture reduces the required amount of training data significantly, while simultaneously

Punching resistance of internal slab-column connections with double-headed shear studs

Revista IBRACON de Estruturas e Materiais
Punching shear is a brittle failure mode that may occur in slab-column connections, which may be prevented by using shear reinforcement in the slab-column connection.

MHD Accretion-Disk Winds as X-ray Absorbers in AGNs [PDF]

, 2010
We present the 2D ionization structure of self-similar MHD winds off accretion disks around irradiated by a central X-ray source. Based on earlier observational clues and theoretical arguments, we focus our attention on a subset of these winds, namely ...

Autonomy for MRI Field Cameras: Synchronization, Self‐Calibration, and Sequence Detection

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work aims to provide a workflow for operating NMR field probes in MR scanners independently of pulse programming, scanner TTL trigger pulses and dedicated calibration sequences. Methods An independent timing system and limited prior knowledge about relative probe positions enable synchronous field measurement, probe position ...
