Unstable Actors, Alternating Currents: Reimagining Bureaucratic Knowledge Production in the Technopolitics of Development
Contemporary international development bureaucracies are constituted by and operate through diverse actors whose work requires sustained interaction with changing material landscapes and the changing subjectivities of partners, clients, and intended beneficiaries. Understanding the production of …

Sheath currents, sheath losses, induced sheath voltages and apparent conductor impedances of metal sheathed cables carrying alternating currents
… sheathed single conductor cables are used on alternating current circuits new problems are introduced such as induced sheath voltages and sheath losses. In this thesis it is proposed to consider sheath voltages, currents and losses and line constants for one or two circuits of single conductor …

Doubly-Salient Permanent Magnet Flux-Reversal-Free-Stator Switched Reluctance Machines
… proposed in this report is driven by unipolar currents and uses an asymmetric converter which is used to drive switched reluctance machines. The reason to have a new hybrid machine without the drawbacks of conventional flux-reversal-free-stator SRMs and conventional DSPMs is also described. …

Modeling of carbonization and stalling during radiofrequency ablation and electrosurgery
… and electrosurgery, function by delivering alternating currents in the 100 kHz-1 MHz range to biological tissues. These currents generate electric fields that drive ionic oscillations in intracellular and extracellular fluids, producing localized resistive heating. Depending on the applied …

Study of Second Generation High Temperature Superconductors: Electromagnetic Characteristics and AC Loss Analysis
… and homogeneity. Even if there are no actual alternating currents involved in the DC superconducting magnets mentioned above, they have power dissipation during normal operation (e.g. magnet ramping) and under different background fields. This problem generally goes under the category of “AC …
