Using heterogeneous satellites for passive detection of moving aerial target [PDF]

open access: yes, 2020
Passive detection of a moving aerial target is critical for intelligent surveillance. Its implementation can use signals transmitted from satellites. Nowadays, various types of satellites co-exist which can be used for passive detection.

Constraining the Collisional Nature of the Dark Matter Through Observations of Gravitational Wakes [PDF]

open access: yes, 2001
We propose to use gravitational wakes as a direct observational probe of the collisional nature of the dark matter. We calculate analytically the structure of a wake generated by the motion of a galaxy in the core of an X-ray cluster for dark matter in ...

Logical topology design for IP rerouting: ASONs versus static OTNs [PDF]

open access: yes, 2011
IP-based backbone networks are gradually moving to a network model consisting of high-speed routers that are flexibly interconnected by a mesh of light paths set up by an optical transport network that consists of wavelength division multiplexing (WDM ...

Rapid Prototyping Using FDM: A Fast, Precise, Safe Technology [PDF]

open access: yes, 1992
This paper outlines the use of FDM to speed product design and to streamline the manufacturing process. Time compression, the ability to quickly reduce the time it takes to get new products to market, has increased the pressure on all phases of ...

AX-GADGET: a new code for cosmological simulations of Fuzzy Dark Matter and Axion models [PDF]

open access: yes, 2018
We present a new module of the parallel N-Body code P-GADGET3 for cosmological simulations of light bosonic non-thermal dark matter, often referred as Fuzzy Dark Matter (FDM).

FDM lokal, gemeinsam und vernetzt gestaltet. Proaktiv zum nachhaltigen FDM

open access: yes, 2021
Die interdisziplinäre Initiative "Forschungsdatenmanagement" (FDM) hat das Ziel, alle an der Berlin-Brandenburgischen Akademie der Wissenschaften (BBAW) generierten Forschungsdaten zu ordnen, zu sichern und langfristig verfügbar zu halten. Über einen Stakeholder-orientierten Ansatz wird eine einheitliche FDM-Strategie entwickelt, welche die lückenlose ...

Pulp-Capping with Mineral Trioxide Aggregate

open access: yesActa Medica Bulgarica, 2015
There are two considerations for direct pulp capping - accidental mechanical pulp exposure and exposure caused by caries. Mineral trioxide aggregate (MTA) was used as pulp-capping material to preserve the vitality of the pulpal tissues.
