The Effects of Different Auditory Feedback Conditions on Speech Rate and Self-Perceptions of Speech
… read a standardized passage under six auditory feedback conditions: DAF; masking; 1, 3, and 5 millisecond delayed, amplified fundamental frequency; and normal auditory feedback. Dependent variabes were rate and self-perceptions of speech. Research hypotheses were: 1) any manipulation of auditory …

Design and analysis of an active power factor correction circuit
… results. Design guidelines for the low-frequency feedback network are presented. Small-signal closed-loop responses are measured with an experimental power factor circuit.

Introduction of a Variable Inductance Transformer for the Design of Resonant Power Converters
… by both the winding layout and the operating frequency. In this thesis, three new semi-analytical methods for calculating the frequency-independent leakage inductance, and a novel semi-analytical method for evaluating the frequency-dependent leakage inductance are proposed. These methods can …

Critical Evaluation of DC-Grid and Strong Grid-Forming Wind Generator Systems
… operation is achieved through proper grid frequency feedback in the MG control. The second part presents the design of a non-permanent magnet alternative through a triple-three-phase wound rotor synchronous generator (T-WRSG) optimized for DC grid applications. A multi-stage optimization …

Probing charge motion in next-generation semiconductors with scanned probe microscopy
… force microscopy measurement and the alternative feedback-free time-resolved electric force microscopy. We show that for sample time constants faster than the inverse cantilever angular frequency, feedback-free time-resolved electric force microscopy is sensitive mainly to the size of the abrupt …

Semiconductor-generated entangled photons for hybrid quantum networks
… allow for reversible fine-tuning of the emission frequency. In a next step, active feedback is employed to stabilize the frequency of single photons emitted by two separate quantum dots to an atomic rubidium standard. The transmission of a rubidium-based Faraday filter serves as the error signal …

Equivalent Circuit Model for Current Mode Controls and Its Extensions
… high order harmonics play important role in the feedback control. This is the reason for the difficulty in obtaining the small-signal model for current-mode control in the frequency domain. A continuous time domain model was recently proposed as a successful model for current-mode control …
