The dusty heart of nearby active galaxies. II. From clumpy ...
With the possibilities of high spatial resolution imaging and spectroscopy as well as infrared (IR) interferometry, the dusty environments (= "dusty torus") of active galactic nuclei (AGN) are now in reach of observations. Following our Paper I on ground-based mid-IR spectro-photometry, we present an upgrade to our radiative transfer model of three-dimensional clumpy dust tori.

Dust Collection System: What Is It? How Does It Work, Types
A dust collection system is a system that removes particulate contaminants from the air in production facilities, workshops, and industrial complexes. The system cleans air by forcing it through a series of airtight filters. Once the air is cleaned, it is expelled outside or recirculated, after it has achieved the proper emission's standards.

Abstract: This paper proposes and compares three iterative approaches for handling discrete variables in optimal power flow (OPF) computations. The first two approaches rely on the sensitivities of the objective and inequality constraints with respect to discrete variables. They set the discrete variables values either by solving a mixed-integer linear programming (MILP) problem or by using a ...
