The Role of III-V Substrate Roughness and Deoxidation Induced by Digital Etch in Achieving Low Resistance Metal Contacts

open access: yesCrystals, 2017
To achieve low contact resistance between metal and III-V material, transmission-line-model (TLM) structures of molybdenum (Mo) were fabricated on indium phosphide (InP) substrate on the top of an indium gallium arsenide (InGaAs) layer grown by molecular

Detecting serial arc in low-voltage electrical installations using modern protective components [PDF]

open access: yesTehnika, 2014
This paper presents an overview of the problem of detecting faults in low voltage electrical installations which are not normally detectable by the regulated electrical periodic verification inspections nor can be recognized by any classical protection ...

Electrical behaviour, characteristics and properties of anodic aluminium oxide films coloured by nickel electrodeposition [PDF]

open access: yes, 2010
Porous anodic films on 1050 aluminium substrate were coloured by AC electrodeposition of nickel. Several experiments were performed at different deposition voltages and nickel concentrations in the electrolyte in order to correlate the applied electrical

Electrical network and Lie theory [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Curtis-Ingerman-Morrow studied the space of circular planar electrical networks, and classified all possible response matrices for such networks. Lam and Pylyavskyy found a Lie group $EL_{2n}$ whose positive part $(EL_{2n})_{\geq 0}$ naturally acts on ...

Antarctic subglacial drilling rig: Part IV. Electrical and electronic control system

open access: yesAnnals of Glaciology, 2021
In many cases, the efficiency and safety of a drilling project depend on the reliability of the electrical and electronic control system, as the process progresses without visual access of the operator.

Low temperature thermal properties of mesoscopic normal-metal/superconductor heterostructures [PDF]

open access: yes, 2001
Although the electrical transport properties of mesoscopic metallic samples have been investigated extensively over the past two decades, the thermal properties have received far less attention.

Electrical Spare Parts Demand Forecasting

open access: yesElektronika ir Elektrotechnika, 2014
In this paper is presented a research of electrical spare parts demand forecasting through application of conventional (moving average, exponential smoothing and naive theory), more sophisticated forecasting techniques (support vector regression, feed-forward neural networks) and adaptive model selection methodologies.

Energy demand prediction for the implementation of an energy tariff emulator to trigger demand response in buildings [PDF]

open access: yes, 2019
Buildings are key actors of the electrical gird. As such they have an important role to play in grid stabilization, especially in a context where renewable energies are mandated to become an increasingly important part of the energy mix.

Scattering of ECRF waves by edge density fluctuations and blobs

open access: yesEPJ Web of Conferences, 2015
The scattering of electron cyclotron waves by density blobs embedded in the edge region of a fusion plasma is studied using a full-wave model. The full-wave theory is a generalization of the usual approach of geometric optics ray scattering by blobs ...
