Magnetic Fields for Electropolishing Improvement: Materials and Systems

Response of Materials Subjected to Magnetic Fields

This research program examined the interaction of conducting materials with magnetic fields through a series of experiments, the development of analytical models and the development and testing of numerical models. The experiments were a series of drop tests of conducting spheres through strong magnetic field gradients and were used for the development and validation of the analytical and numer...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Hyperbolic Dynamical Systems Andgeneration of Magnetic Fields

GENERATION OF MAGNETIC FIELDS BY PERFECTLY CONDUCTING FLUIDS. (1) Rafael de la Llave 2 3 Mathematics Department The University of Texas at Austin Austin TX 78712 Abstract. We study the spectrum of the operator describing the growth of magnetic elds in an in nitely conducting, incompressible uid. We show that, in many circumstances, it consists of an anulus and also give characterization of this...

Magnetic Fields Ignorable Magnetic Fields Non Ignorable Magnetic Fields Important Magnetic Fields Dominant

Magnetic fields are considered to be dominant when εB ≥ εK , being εB = B /8π the magnetic energy density and εK = 1/2ρθ 2 the rotation energy density, for a conventional moderate B= 1 μG. They are considered to be negligible when εB < εK for B ∼ 10μG. With no assumption and no theoretical calculation, we show that magnetic fields cannot be ignored in the outer parts of a galaxy like the Milky ...
