The space charge smoothing factor
Journal of the Institution of Electrical Engineers, 1951The author has recently expressed the properties of a planar diode in terms of a set of differential coefficients, many of which can be experimentally determined. In the present paper these differential coefficients are used to derive a relation between the anode-current fluctuations and the fluctuation in the total emission.The fluctuation in the ...

“Smooth Space” for Avatars [PDF]
, 2015 During the years of Suprematism, between 1919 and 1923 in Russia, one of the movement's most significant contributors, architect, artist and designer El Lissitzky developed a series of works which he entitled “Prouns,” a name the exact meaning of which El Lissitzky never fully revealed, although he later described the purpose of his creations as ...

The Tangent Space and Smoothness
2000In this chapter we introduce the tangent space at a point and review several criteria for smoothness for arbitrary varieties. It is well known that the tangent space at a point of an irreducible variety always has dimension at least as large as the dimension of the variety. Furthermore, a variety is smooth at a point if the dimensions are equal. If one

The basic definition of a smooth point of an algebraic variety is analogous to the corresponding one from differential geometry. We start with the affine case; suppose X ⊂A n is an affine variety of pure dimension k, with ideal I(X) =(f 1 ,..., f i ). Let M be the l × n matrix with entries ∂f i /∂x j . Then it’s not hard to see that the rank of M is at

Smoothness and Function Spaces
2008We embark on the study of smoothness with a quick examination of differentiability properties of functions. There are several ways to measure differentiability and numerous ways to quantify smoothness. In this chapter we measure smoothness using the Laplacian, which is easily related to the Fourier transform.
