Design of 200 W full digital switching power supply

Dianzi Jishu Yingyong, 2019
By using a bridgeless PFC and a half-bridge LLC resonant converter as the main conversion topology of the digital switching power supply, the all-digital control PFC and DC-DC converter based on the STM32 series of microcontrollers, firstly the digital ...

Remarks on fixed point assertions in digital topology, 9

Applied General Topology
We continue a discussion of published assertions that are incorrect, incorrectly proven, or trivial, in the theory of fixed points in digital topology.

Concepts of digital topology

Topology and its Applications, 1992
In computer graphics and image processing one sometimes wants to apply the concept of connectedness in binary images. Here a binary image can be viewed as a partition of a set of image points \(V\) into two subsets; points in one subset are called black points, and points in the other subset are called white points.

On Generalized Digital Topology and Root Images of Median Filters

Journal of New Theory, 2018
In this paper, we extend the concepts of semi-open sets and λ-open sets in the digital topology. In addition, we introduce the concepts of regular semi-open and regular λ-open sets.

Topology as a way of creativity and innovation in the design process

Journal of Architecture, Art & Humanistic Science, 2018
Due to scientific and technological progress, and after the digital revolution, new design trends have emerged, based on new foundations and ideas in terms of form and content cannot be reached by the designer under the tools of traditional design.

A New Class of Closed Set in Digital Topology

Journal of New Theory, 2020
The purpose of this paper is to introduce a new class of closed set calledg*w\alpha-closed sets in digital topology. We establish a relationship between closed andg*w\alpha-closed sets in digital topology.

Subdivision-based homotopy equivalence of digital circles

Applied General Topology
A direct translation of the notion of homotopy equivalence from algebraic topology to digital images leads to a much more rigid definition in the context of digital topology. This results in two digital circles of different radii being not homotopic.

Models of topological geometry as a trend for creativity and innovation in the design process [PDF]

Kafrelsheikh Journal of Information Sciences
With the growth of science and technology, along with the rise of the digital revolution andfuture sciences, new design trends have emerged based on fresh ideas about form and content. De-signers cannot achieve this with traditional methods.

Three-dimensional digital topology

Information and Control, 1981
Basic concepts of connectedness, cavities, and holes are defined for subsets of three-dimensional arrays. Three-dimensional arcs and curves are also defined and characterized.
