The Max-Line-Formation Problem [PDF]
CoRR, 2021 We consider n robots with limited visibility: each robot can observe other robots only up to a constant distance denoted as the viewing range. The robots operate in discrete rounds that are either fully synchronous (FSync) or semi-synchronized (SSync).

Counting Critical Formations on a Line
SIAM Journal on Control and Optimization, 2014 Formation shape control for a collection of point agents is concerned with devising decentralized control laws which ensure that the formation will move so that certain interagent distances approximate prescribed values as closely as possible.

Animation of Flocks Flying in Line Formations [PDF]
Artificial Life, 2011 We provide a biologically motivated technique for modeling and animating bird flocks in flight, which produces plausible and realistic-looking flock animations. While most previous approaches have focused on animating cluster formations, this article introduces a technique for animating flocks that fly in certain patterns, so-called line formations. We

On the formation of lines in quantum phase space
Journal of Physics A: Mathematical and Theoretical, 2023 Abstract We theoretically study the formation of lines in phase space using Wigner’s distribution W . In trapped quantum systems such lines form generically, crisscrossing phase space

THE FORMATION OF THE Hα LINE IN THE SOLAR CHROMOSPHERE [PDF]
The Astrophysical Journal, 2012 We use state-of-the-art radiation-MHD simulations and 3D non-LTE radiative transfer computations to investigate \Halpha\ line formation in the solar chromosphere and apply the results of this investigation to develop the potential of \Halpha\ as diagnostic of the chromosphere.

Line formation in the wind of Alpha Cygni [PDF]
International Astronomical Union Colloquium, 1981 AbstractWe summarize the results of recent IUE observations of the spectra of α Cygni and discuss possible explanations for the Doppler-shifted pure absorption profiles in the resonance lines of the singly ionized metals. The results of detailed modeling for MgII λ 2795, 2802 are presented, and discussed in the context of observations of α Cyg in the ...

Cyclotron line formation in a relativistic outflow [PDF]
AIP Conference Proceedings, 1996 There is mounting evidence that, if gamma-ray bursters are Galactic in origin, they are located in a Galactic corona at distances greater than 100 kpc. This has created a need to explore new models of cyclotron line formation. In most previous calculations the line-forming region was modeled as a static slab of plasma, optically thin to continuum ...

A Note on the Formation of Stellar Absorption Lines [PDF]
The Astrophysical Journal, 1936 Microphotometer measures of the total absorptions of lines of O II within the wing of Hγ, and of CaH within the wing of HЄ, show departures from the normal absorptions predicted from the multiplet intensities of these lines. The departures increase with the wing absorption, but the effect is more pronounced for O II than for CaH.

Проект Байкал, 2022 The article is devoted to the features and origins of Nikolay Milyutin’s urban planning theory. Written long before the completion of his formal education, his book “Socialist city” became extremely popular among the planners and architects of the 20th century, but the real extent of his contribution to the practice of building new cities, as well as ...

Pattern formation in the lateral line of zebrafish
Mechanisms of Development, 2001 The lateral line of fish and amphibians is a sensory system that comprises a number of individual sense organs, the neuromasts, arranged in a defined pattern on the surface of the body. A conspicuous part of the system is a line of organs that extends along each flank (and which gave the system its name).
