In this paper, a new hierarchical approach for part-based object recognition is proposed. Object detection methods based on Implicit Shape Model (ISM) efficiently handle deformable objects, occlusions and clutters. The structure of each object in ISM is defined by a spring like graph, hence parts independently vote to object properties. We introduce hierarchical ISM in which structure of each o...

The interstellar medium seems to have an underlying fractal structure which can be characterized through its fractal dimension. However, interstellar clouds are observed as projected two-dimensional images, and the projection of a tridimensional fractal distorts its measured properties. Here we use simulated fractal clouds to study the relationship between the tri-dimensional fractal dimension ...

An accurate knowledge of the mineralogy (chemical composition and crystal structure) of the silicate dust in the interstellar medium (ISM) is crucial for understanding its origin in evolved stars, the physical and chemical processing in the ISM, and its subsequent incorporation into protostellar nebulae, protoplanetary disks and cometary nuclei where it is subjected to further processing. While...

Chandra observation of the central region of the A1060 cluster of galaxies resolved X-ray emission from two giant elliptical galaxies, NGC 3311 and NGC 3309. The emission from these galaxies consists of two components, namely the hot interstellar medium (ISM) and the low-mass X-ray binaries (LMXBs). We found the spatial extent of the ISM component was much smaller than that of stars for both ga...

The Southern Galactic Plane Survey (SGPS) is a radio survey in the 21 cm H I line and in 1.4 GHz full-polarization continuum, observed with the Australia Telescope Compact Array and the Parkes 64m single dish telescope. The survey spans a Galactic longitude of 253 < l < 358 and a latitude of |b| < 1 at a resolution of 100 arcsec and a sensitivity below 1 mJy/beam. This paper presents interferom...

We review what is currently known about the structure of interstellar material in the solar neighborhood, emphasizing how observations from the Hubble Space Telescope (HST) have improved our understanding of how interstellar gas is distributed near the Sun. The nearby ISM is not uniform but shows variations in both temperature and metal abundances on distance scales of just a few parsecs. The o...

Distortion prediction of a welded structure is an important way to improve work efficiency and ensure product quality during the fabrication process. Recently, widely used approaches for evaluating residual deformation include thermo-elastic-plastic finite element method (TEP-FEM) inherent strain (ISM). The former can accurately simulate entire welding process with excessive computational time,...

We have investigated the physical and chemical status of the pre-protostellar core B68. A previous extinction study suggested that the density profile of B68 is remarkably consistent with a Bonnor-Ebert sphere with 2.1 M at 16 K. We mapped B68 in C3H2, CCS, and NH3 with the Deep Space Network (DSN) 70m telescope at Goldstone. Our results show that the NH3 peak coincides with the dust continuum ...

Abstract A major question in the field of star formation is how molecular clouds form out diffuse interstellar medium (ISM). Recent advances 3D dust mapping are revolutionizing our view structure ISM. Using highest-resolution map to date, we explore a nearby star-forming region, which includes well-known Perseus and Taurus clouds. We reveal an extended near-spherical shell, 156 pc diameter (her...

We mapped a 13×22 pc region in emission from 492 GHz [C I] and, for the first time, 551 GHz 13CO(5→4) in the giant molecular cloud M17SW. The morphologies of the [C I] and 13CO emission are strikingly similar. The extent and intensity of the [C I] and 13CO(5→4) emission is explained as arising from photodissociation regions on the surfaces of embedded molecular clumps. Modeling of the 13CO(5→4)...
