Stellar Streams as Probes of Dark Halo Mass and Morphology: A Bayesian Reconstruction

open access: yes, 2011
Tidal streams provide a powerful tool by means of which the matter distribution of the dark matter halos of their host galaxies can be studied. However, the analysis is not straightforward because streams do not delineate orbits, and for most streams ...

Intrinsic Axis Ratio Distribution of Early-type Galaxies From Sloan Digital Sky Survey [PDF]

open access: yes, 2007
Using Sloan Digital Sky Survey Data Release 5, we have investigated the intrinsic axis ratio distribution (ARD) for early-type galaxies. We have constructed a volume-limited sample of 3,922 visually-inspected early-type galaxies at $0.05 \leq z \leq 0.06$

A new smooth failure criterion for concrete inspired by Lubliner's condition

open access: yesStructural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

On the behaviour of streams in angle and frequency spaces in different potentials [PDF]

open access: yes, 2016
We have studied the behaviour of stellar streams in the Aquarius fully cosmological N-body simulations of the formation of Milky Way halos. In particular, we have characterised the streams in angle/frequency spaces derived using an approximate but ...

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1247-1269, May 2026.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

Development of a Computer Vision-Based Three-Dimensional Reconstruction Method for Volume-Change Measurement of Unsaturated Soils during Triaxial Testing [PDF]

open access: yes, 2019
Problems associated with unsaturated soils are ubiquitous in the U.S., where expansive and collapsible soils are some of the most widely distributed and costly geologic hazards.

The orientation of elliptical galaxies

open access: yes, 2010
We determine the orientations of the light distribution of individual elliptical galaxies by combining the profiles of photometric data from the literature with triaxial models. The orientation is given by a Bayesian probability distribution.

Vertical‐Component Seismic Response and System Identification of a 52‐Story High‐Rise Building Using Earthquake Data

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

True triaxial modeling test of high-sidewall underground caverns subjected to dynamic disturbances

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Seismicity resulting from the near- or in-field fault activation significantly affects the stability of large-scale underground caverns that are operating under high-stress conditions.

Development of experimental concepts for investigating the strength behavior of fine-grained cohesive soil in the Spacelab/space shuttle zero-g environment [PDF]

open access: yes
Three different sets of tests are proposed for the NASA Spacelab experimental program. The first of tests, designed to measure the true cohesion of several different soils, would be carried out in space through use of a specially prepared direct shear ...
