MLPNN and Ensemble Learning Algorithm for Transmission Line Fault Classification

International Transactions on Electrical Energy Systems
Recently, Bangladesh experienced a system loss of 11.11%, leading to significant power cuts, largely due to faults in power transmission lines. This paper proposes the XGBoost machine learning method for classifying electric power transmission line ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Fault detection in transmission networks of power systems

International Journal of Electrical Power & Energy Systems, 2011
Abstract An online fault detection scheme for a sample power system is introduced in this paper. The detection approach is based on the use of a variable structure system called “sliding mode observer”, where information contained in the output measurements is utilized to detect the onset of faults in the transmission network of the sample power ...

Transmission line fault analysis using actuating relays and Atmega 328P controller [PDF]

, 2023
Since transmission lines account for 80–86% of power system problems, protecting transmission lines is a critical concern. This research proposes a method to identify and categorize various short circuit defects on transmission lines. Various operational

Memory Fault Simulator for Static-Linked Faults [PDF]

, 2006
Static linked faults are considered an interesting class of memory faults. Their capability of influencing the behavior of other faults causes the hiding of the fault effect and makes test algorithm design and validation a very complex task.

Superconducting power link for power transmission and fault current limitation

Physica C: Superconductivity, 2001
Superconducting power links (SUPERPOLI) will offer the opportunity for low-loss power transmission of high nominal currents and fault current limitation simultaneously in a single device. This paper presents the status of European SUPERPOLI project where the long term goal is to build a GVA class, 20 kV, three-phased, 200 m long superconducting power ...

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.
