Iron Loss Analysis of PMSM in Different Driving Conditions

open access: yes机车电传动, 2012
The amount of PM iron loss varied according to different driving conditions. In this paper, the actual current of the prototype motor was used to perform 2D finite -element analysis and obtain the flux-density waveform in conditions of no-load, maximum ...

FPGA-based implementation of the back-EMF symmetric-threshold-tracking sensorless commutation method for brushless DC-machines [PDF]

open access: yes, 2013
The operation of brushless DC permanent-magnet machines requires information of the rotor position to steer the semiconductor switches of the power-supply module which is commonly referred to as Brushless Commutation. Different sensorless techniques have

Invertible definitions.

open access: yesNotre Dame Journal of Formal Logic, 1987
This paper has two parts: A brief philosophical motivation followed by a technically complex development of conditions for certain types of definability. From some suggestion of P. Geach about when having the concept of one relation is to have the concept of another relation, the author characterizes the notion of informationally equivalent relations ...

KLK7 overexpression promotes an aggressive phenotype and facilitates peritoneal dissemination in colorectal cancer cells

open access: yesFEBS Open Bio, EarlyView.
KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Invert to Learn to Invert

open access: yes, 2019
Iterative learning to infer approaches have become popular solvers for inverse problems. However, their memory requirements during training grow linearly with model depth, limiting in practice model expressiveness. In this work, we propose an iterative inverse model with constant memory that relies on invertible networks to avoid storing intermediate ...

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein

open access: yesFEBS Open Bio, EarlyView.
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Design and development of model inverter

open access: yesDianzi Jishu Yingyong, 2019
To meet the requirement of practical teaching of electromechanics course, a model inverter for the school laboratory is designed, which converts the power supply into another arbitrary frequency electric energy to drive the three-phase asynchronous motor
