Abstract:

Here, we present experimental and analytical results of a preventive approach applied to a fault-mode phenomenon caused by electrodes or power-source failure in a no-insulation (NI) high-temperature superconducting REBa2Cu3O7−x (REBCO, RE = rare earth) magnet. It is generally agreed that the NI magnets, at least those of laboratory scale, are self-protected from overheating and, therefore, from quenching, chiefly because of turn-to-turn current bypassing unique to NI. However, these NI magnets do experience unexpected quenches, e.g., when the current through the magnet suddenly drops due to th

Abstract:

Abstract In this paper the focus is on thermal and electrical design aspects of a NbTi-based demonstrator magnet for magnetic density separation (MDS) that is being constructed at the University of Twente. MDS is a recycling technology that allows the separation of non-magnetic particles based on their mass density, using a vertical magnetic field gradient and a ferrofluid. To minimize the distance between the planar array of racetrack coils and the ferrofluid bath, the system is conduction-cooled. First the thermal design is presented, which shows that the coils can operate below 4.5 K with s

A new programmable oscillator using two negative first-generation current-conveyors, three grounded capacitors, and two grounded resistors is presented. The proposed circuit enjoys independent oscillation control through a single grounded resistor and independent frequency control through a single grounded capacitor. Replacing one of the grounded resistors by a digitally programmable resistor results in a programmable oscillator.

Abstract:

Energy harvesting from structural vibrations using an array of multifunctional resonators based on the theory of locally resonant materials is demonstrated. Such locally resonant structures exhibit a stop band for elastic wave propagation. The band gap frequency range depends on the local resonance frequency of the microstructure. One method to realize this is through the use of an array of embedded resonators where the external work done is stored as kinetic energy of the internal mass when the forcing frequency is close to the local resonance frequency. This mechanism can be used to harvest

The paper aims to propose a more realistic low frequency noise and TCR mechanisms in polymer thick film resistors. The variation of low frequency noise (also called current noise) and TCR of polymer thick film resistor, namely, PVC-graphite thick film resistor, with parameters such as high volume fraction and grain size has been studied. A model is proposed to explain the observed variations, which assumes that the texture of the polymer thick film resistor consists of densely packed conducting particles with a cavity at the center of the structure.

As temperature rises, the resistance value increases, and the TCR becomes positive.On the contrary, if the thermal expansion coefficient of the resistor is larger than that of the substrate, the as-fired resistor is being st
