Spreading of Localized Information across an Entire 3D Electrical Resistivity Volume via Constrained EMI Inversion Based on a Realistic Prior Distribution.
Publication Type: Academic Journal
Source(s): Remote Sensing. Aug2023, Vol. 15 Issue 16, p3993. 25p.
Abstract: Frequency-domain electromagnetic induction (EMI) methods are commonly used to map vast areas quickly and with minimum logistical efforts. Unfortunately, they are often characterized by a very limited number of frequencies and severe ill-posedness. On t...
Effect of induced defects on conduction mechanisms of noble-gas-implanted ScN thin films.
Publication Type: Academic Journal
Source(s): Journal of Applied Physics. 8/7/2023, Vol. 134 Issue 5, p1-8. 8p.
Abstract: Noble-gas implantation was used to introduce defects in n-type degenerate ScN thin films to tailor their transport properties. The electrical resistivity increased significantly with the damage levels created, while the electron mobility decreased rega...
Microstructures and Electrical Resistivity of Aluminum–Copper Joints.
Publication Type: Academic Journal
Source(s): Metals (2075-4701). Aug2023, Vol. 13 Issue 8, p1474. 12p.
Abstract: Using pulsed double electrode-gas metal arc welding, aluminum wires are joined to copper plates with fillers of different fractions of silicon. Two layers of different microstructures are formed near the Al-Cu interface: one consists of a hypoeutectic ...
Assessment of AC Corrosion Probability in Buried Pipelines with a FEM-Assisted Stochastic Approach.
Publication Type: Academic Journal
