Descriptional complexity of pushdown store languages [PDF]

open access: yes, 2012
It is well known that the pushdown store language P(M) of a pushdown automaton (PDA) M — i.e., the language consisting of words occurring on the pushdown along accepting computations of M — is a regular language. Here, we design succinct nondeterministic

Wind Tunnel Study on Migration Characteristics of the Aerosols Released from Point-source in Roughness Sub-layer

open access: yesTaiyuan Ligong Daxue xuebao, 2022
The transportation was simulated of aerosol particles released from point-source over the typical hilly terrain in a wind tunnel. The Particle Dynamic Analysis technique (PDA) was used to investigate the effects of wind speed (1 m/s, 2 m/s), particle ...

Color Engineering of Silicon Nitride Surfaces to Characterize the Polydopamine Refractive Index [PDF]

open access: yes, 2018
A simple methodology to generate polydopamine (PDA) surfaces featured with color due to thin-film interference phenomena is presented. It is based on depositing ultra-thin films of polydopamine on a Si/Si 3 N 4 wafer that exhibits an interferential ...

Efficient absolute aspect determination of a balloon borne far infrared telescope using a solid state optical photometer [PDF]

open access: yes, 1999
The observational and operational efficiency of the TIFR 1 meter balloon borne far infrared telescope has been improved by incorporating a multielement solid state optical photometer (SSOP) at the Cassegrain focus of the telescope. The SSOP is based on a

From nominal to true a posteriori probabilities: an exact Bayesian theorem based probabilistic data association approach for iterative MIMO detection and decoding

open access: yes, 2013
It was conventionally regarded that the existing probabilistic data association (PDA) algorithms output the estimated symbol-wise a posteriori probabilities (APPs) as soft information.
