Modular Curves, Modular Surfaces, and Modular Fourfolds

We begin with some general remarks. Let X be a smooth projective variety of dimension n over a field k. For any positive integer p < n, it is of interest to understand, modulo a natural equivalence, the algebraic cycles Y = ∑ j mjYj lying on X, with each Yj closed and irreducible of codimension p, together with codimension p + 1 algebraic cycles Zj = ∑ i rijZij lying on Yj , for all j. There is...

A Proposed Model for Evaluating Modular Education

Introduction: Educational evaluation is one of the main elements of educational systems. It also has a particular role in different educational standards such as ISO 10015. It seems that oral and written examinations are not enough for an effective evaluation of instructions. In order to accomplish an efficient educational evaluation, an evaluation model was designed for educational assessment ...

modular chromatic number of $c_m square p_n$

a modular $k$-coloring, $kge 2,$ of a graph $g$ without isolated vertices is a coloring of the vertices of $g$ with the elements in $mathbb{z}_k$ having the property that for every two adjacent vertices of $g,$ the sums of the colors of the neighbors are different in $mathbb{z}_k.$ the minimum $k$ for which $g$ has a modular $k-$coloring is the modular chromatic number of $g.$ except for some s...

A Generalized Modular Multilevel Current Source Inverter

This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...
