Boundary box regression is a crucial step in object detection, directly influencing the model's ability to accurately locate objects. Traditional Intersection over Union (IoU) loss functions struggle to provide effective gradient information when ...

In this paper, we focus on the global regularity of smooth solutions for 2D incompressible generalized magnetohydrodynamics equations with a velocity damping term and the standard Laplacian magnetic diffusion. We show that this system has the ...

The field-oriented-control algorithm in 60° coordinate system for permanent magnet synchronous motor is described in this paper. Field-oriented-control algorithm consists of several parts and in 60° coordinate system the expression form of ...

With the continuous development of 5G (5th generation mobile networks) communication technology, increasing attention has been paid to the integration of 5G technology and vertical industry. Based on the consideration of power security, the large-scale ...

In this paper, a three-phase two-stage LC-type three-level electrolytic capacitor-less grid-connected inverter with multiple PV arrays input is proposed. The multiloop and the interleaved control method was adopted for the three-level boost DC/DC part, ...

This paper proposed a modified virtual synchronous generator (VSG) control strategy for single-phase inverter application. In order to achieve zero-error tracking for reactive power output, an improved reactive-voltage control approach for the outer layer ...

In this paper, we consider large time behaviour of solutions to the 3D Navier–Stokes equations with damping term ${|u|}^{\beta -1}u$($\beta \ge 1$). For $\beta >\frac{7}{3}$, we derive decay rates of the $L^2$-norm of the solutions. By using Fourier splitting method, we also prove that ...

In this paper, a full incompressible magneto-micropolar system is investigated. We prove the local well-posedness of strong solutions to the full system with vacuum. Moreover, previous compatibility conditions on the initial data are also moved.

A novel transformerless two-stage photovoltaic (PV) grid-connected inverter is introduced in this paper. The system is composed of three-level boost (TL-Boost) DC/DC circuit and three-phase T-type eight-switch DC/AC topology. By using the multiloop ...
