A Diamond Shaped Multilevel Inverter With Dual Mode of Operation [PDF]

open access: yesIEEE Access, 2021
This study presents a novel multilevel inverter structure that can operate in both switched capacitor and asymmetric DC source modes. In the first mode, it can produce seven-level output voltage employing two switched capacitors and one single DC supply. The five-level output voltage is produced while operating the second mode.

Gradient layers of boron doped diamond on titanium substrates

open access: yes, 2007
For the deposition of well-adhesive, low-doped diamond layers on titanium substrates a gradient layer is designed. At first a highly boron-doped diamond layer is deposited, which shows good adhesion to the titanium substrate, followed by a low-boron ...

A note on the diamond operator

open access: yesComputability, 2020
We show that if [Formula: see text] and [Formula: see text], then [Formula: see text], where ⋆ and ◇ are the following operations in the Weihrauch lattice: ⋆ is the compositional product, which allows the use of two principles in sequence, while the diamond operator ◇ allows an arbitrary but finite number of uses of the given principle in sequence ...

On the generalized Bessel heat equation related to the generalized Bessel diamond operator [PDF]

open access: yes, 2011
In this article, we study the equation with the initial condition u(x, 0) = f(x) for x ?. Here the operator is called the Generalized Bessel Diamond Operator, iterated k times, and is defined by where k and m are positive integers, p + q = n, Bxi = 2vi =

The Contingency of Possibility

open access: yesPrincipia: An International Journal of Epistemology, 2016
In this paper we criticize the way possibility is characterized in contemporary modal logic through the diamond operator. We explain that it does not match with the usual notion of possibility and that this notion is better described by the vertex Y of ...

Energy consumption and wear rate of diamond beads during operation of a diamond wire saw

open access: yesE-Zbornik, elektronički zbornik radova Građevinskog fakulteta, 2023
Diamond wire saws are indispensable machines for the extraction and processing of dimension stones. The cutting speed, energy consumption and wear rate of the diamond beads are the most important factors in assessing the efficiency of a diamond wire saw. The parameters that influence the efficiency of the diamond wire saw can be divided into controlled
