Generalized Characteristic Function Loss for Crowd Analysis in the Frequency Domain

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2023
Typical approaches that learn crowd density maps are limited to extracting the supervisory information from the loosely organized spatial information in the crowd dot/density maps.

Numerical Approximation of Probability Mass Functions via the Inverse Discrete Fourier Transform

, 2012
First passage distributions of semi-Markov processes are of interest in fields such as reliability, survival analysis, and many others. Finding or computing first passage distributions is, in general, quite challenging.

A general framework for the calculation of the average outage duration of diversity systems over generalized fading channels

IEEE Transactions on Vehicular Technology, 2002
This paper presents two approaches for the calculation of the average outage duration (AOD) of diversity systems over generalized fading channels. First, a "classical" probability density function (pdf)-based approach is used to obtain exact closed-form ...

Secondary metabolites, their structural diversity, bioactivity, and ecological functions: An overview

Physical Sciences Reviews, 2019
Natural products are also called secondary metabolites to distinguish them from the primary metabolites, i.e. those natural compounds like glucose, amino acids, etc.
