Radio observations of NGC 6388: an upper limit on the mass of its central black hole

, 2010
We present the results of deep radio observations with the Australia Telescope Compact Array (ATCA) of the globular cluster NGC 6388. We show that there is no radio source detected (with a r.m.s. noise level of 27 uJy) at the cluster centre of gravity or

X-ray Properties of Black-Hole Binaries [PDF]

, 2006
We review the properties and behavior X-ray binaries that contain an accreting black hole. The larger majority of such systems are X-ray transients, and many of them were observed in daily pointings with RXTE throughout the course of their outbursts. The

INTEGRAL/RossiXTE high-energy observation of a state transition of GX 339-4 [PDF]

, 2006
On 2004 August 15, we observed a fast (shorter than 10 hours) state transition in the bright black-hole transient GX 339-4 simultaneously with RossiXTE and INTEGRAL. This transition was evident both in timing and spectral properties.

Dynamic Test of Negative Stiffness Damped Outrigger With Damping Amplification

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 4, Page 1141-1155, 10 April 2025.
ABSTRACT This paper proposed a novel negative stiffness damped outrigger with damping amplification (NSDO‐DA) through a smart combination of an L‐shape lever, a precompressed disc spring brace (DSB), and a viscous damper. A theoretical model of the NSDO‐DA considering nonlinear adaptive negative stiffness, damping amplification of nonlinear viscous ...

Radio emission and jets from microquasars

, 2009
To some extent, all Galactic binary systems hosting a compact object are potential `microquasars', so much as all galactic nuclei may have been quasars, once upon a time.

Low/hard state of microquasars at low luminosities [PDF]

, 2008
Galactic black hole transients (GBHTs) spend most of their time in the low/hard spectral state during the outburst decay. This state exhibits a hard X-ray spectrum with X-ray flux correlating with both the radio and the infrared flux.

Strength evaluation of concrete corbels cast in a different stage from the column

Revista IBRACON de Estruturas e Materiais
The design of a precast structural system requires joints between the structural elements, and concrete corbels are commonly used in the connection between beams and columns.

Strut-tie method of design and possible serviceability problems: an exploration by NLFE [PDF]

, 2000
The strut and tie method presents a rational and consistent approach to the design of all parts in a reinforced concrete structure. With this approach, the load carrying mechanism of the structure is represented by approximating the compressive stress

Time-Dependent Synchrotron and Compton Spectra from Jets of Microquasars

, 2006
Jet models for the high-energy emission of Galactic X-ray binary sources have regained significant interest with detailed spectral and timing studies of the X-ray emission from microquasars, the recent detection by the HESS collaboration of very-high ...
