Forming Galaxies with MOND [PDF]
, 2008 Beginning with a simple model for the growth of structure, I consider the dissipationless evolution of a MOND-dominated region in an expanding Universe by means of a spherically symmetric N-body code.

Frequency Stability of Synchronous Machines and Grid-Forming Power Converters [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 An inevitable consequence of the global power system transition toward nearly 100% renewable-based generation is the loss of conventional bulk generation by synchronous machines (SMs), their inertia, and accompanying frequency- and voltage-control ...

The Global Schmidt law in star forming galaxies [PDF]
, 1997 Measurements of Hα, H I, and CO distributions in 61 normal spiral galaxies are combined with published far-infrared and CO observations of 36 infrared-selected starburst galaxies, in order to study the form of the global star formation law over the full ...

Simulation of forming of UFG Ti-6-4 alloy at low temperature of superplasticity [PDF]
Компьютерные исследования и моделирование, 2017 Superplastic forming of Ni and Ti based alloys is widely used in aerospace industry. The main advantage of using the effect of superplasticity in sheet metal forming processes is a feasibility of forming materials with a high amount of plastic strain in ...

The physical properties of star-forming galaxies in the low-redshift universe [PDF]
, 2003 We present a comprehensive study of the physical properties of ∼ 10 5 galaxies with measurable star formation in the Sloan Digital Sky Survey (SDSS). By comparing physical information extracted from the emission lines with continuum properties, we build ...

Formes mathématiques, formes physiques, formes vivantes [PDF]
Le Genre humain, 2019 Chaque forme est une interrogation. Les mathematiques y repondent en termes de structures et de symetries, et elles nous offrent un dictionnaire de formes ideales avec lequel decrire notre perception. La physique nous apprend qu'une forme naturelle revele tout autant les forces et processus qui l'ont engendree que les proprietes de la matiere dans ...

Goethe-Lexicon of Philosophical Concepts, 2021 The concept of form today remains as indispensable to philosophical reflection as it was for Plato and Aristotle. In view of its centrality to Goethe’s work, the concept may thus be considered one of the privileged themes for assessing Goethe’s position in the Western philosophical tradition. The following remarks must pursue a more modest aim.

Synthesis of Calcium-Dialkyldithiophosphate and Evaluation of Its Lubricating Properties
Tribology Online, 2009 Calcium-di-2-ethylhexyldithiophosphate (CaDTP) was synthesized and its lubricating properties were compared with those of zinc-di-2-ethylhexyldithiophosphate (ZnDTP) and chlorinated pentadecane (CP).
