A molecule adsorbed on a metal surface carries an electric dipole moment, and diffuses on the surface. When a collection of identical molecules partially covers the surface, the dipole–dipole interactions, along with other thermodynamic forces, drive the molecules to aggregate into monolayer islands, in the shape of dots or stripes. The dipole– dipole interactions mediate through the electrosta...

In this paper, we present a transient modeling of electromigration (EM) in TSV and TSV-to-wire interfaces in the power delivery network (PDN) of 3D ICs. In particular, we model atomic depletion and accumulation, effective resistance degradation, and full chip-scale PDN lifetime degradation due to EM. Our major focuses are on: (1) timedependent multi-physics EM modeling approach to model TSVs an...

Manipulation of a magnetic state by a spin-polarized current is one of the exciting topics in solid state physics. We succeeded in driving a magnetic domain wall (DW) in magnetic nanowire by an electric current flowing through the wire. Figure 1 (a) shows a schematic illustration of a top view of a sample. One end of the L-shaped wire is connected to a diamond shaped pad which acts as a DW inje...

The detection of magnetic activity enables noncontact and noninvasive evaluation of electrical activity in humans. We review the detection of biomagnetic fields using amorphous metal wire-based magnetic sensors with the sensitivity of a pico-Tesla (pT) level. We measured magnetic fields close to the thoracic wall in a healthy subject sitting on a chair. The magnetic sensor head was mounted perp...

What is a landmine? The purpose of a landmine is to disable, immobilize or kill. It is an explosive device activated either by a person or vehicle, or command detonated by electric wire or radio signal. Most landmines are laid on or just below the surface of the ground and are activated by pressure or trip-wire. Normally manufactured from very durable materials such as plastic, bakelite, concre...

In this paper, we introduce a methodology for the dependability analysis of new automotive safety-relevant systems. With the introduction of safety-relevant electronic systems in cars, it is necessary to carry out a thorough dependability analysis of those systems to fully understand and quantify the failure mechanisms in order to improve the design. Several system level FMEAs are used to ident...

Motivated by a need within the aerospace industry to detect and characterize degradation in the insulation of onboard wires, this thesis reports testing of several extant methods and development of novel capacitive sensors. The work focuses on measuring the electrical parameters resistance and capacitance that are directly related to the material parameters conductivity and permittivity, respec...

A laboratory-scale single-stage electrostatic precipitator (ESP) was designed, built and operated in a wind tunnel. As a "rst step, a series of experiments were conducted to seek the operating conditions for increasing the particle collection e$ciency by varying basic operating parameters including the wire-to-plate spacing, the wire radius, the air velocity, the turbulence intensity and the ap...

Cross-wire welding is a type of electric resistance called projection that used in the production variety products. This paper deals with case where steel wires equal radii are joined together to form reinforced mesh. The objective study determine correlation between parameters and breaking force weld. Each weld cut out from given wire mesh tested separately by destructive testing on universal ...

We investigate the FIR-absorption of short period parallel quantum wires in a perpendicular quantizing magnetic field. The external time-dependent electric field is linearly polarized along the wire modulation. The mutual Coulomb interaction of the electrons is treated self-consistently in the ground state and in the absorption calculation within the Hartree approximation. We consider the effec...
