This paper deals with small-signal analysis of dc–dc converters with sliding mode control. A suitable small-signal model is developed which allows selection of control coefficients, analysis of parameter variation effects, characterization of the closed-loop behavior in terms of audiosusceptibility, output and input impedances, and reference to output transfer function. Unlike previous analyses...

The purpose of this article is to investigate the uniqueness of meromorphic functions sharing five small functions on annuli.

let $r$ be an arbitrary ring and $t$ be a submodule of an $r$-module $m$. a submodule $n$ of $m$ is called $t$-small in $m$ provided for each submodule $x$ of $m$, $tsubseteq x+n$ implies that $tsubseteq x$. we study this mentioned notion which is a generalization of the small submodules and we obtain some related results.

introduction: reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. in large defects, there will be demand for regional pedicle flaps or free flaps. hard palate separates nasal and oral cavities. due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions a...

mirnas are endogenous small noncoding rnas that can regulate many cellular processes. different expression levels of several mirnas have been detected in glioblastomas. function of mirnas and targets have been well studied in recent years. according to these studies, the role of mirnas in glioblastoma pathogenesis have been defined. mirnas have affected many processes in gbm such as apoptosis, ...
