The Winch-Bot : a cable-suspended, under-actuated robot utilizing parametric self-excitation
… the load dynamically based on parametric self-excitation. The generated trajectories can be used for a variety of tasks, from moving material to cyclic inspection of surfaces. The basic principle and design concept of the Winch-Bot are first described, followed by dynamic modeling and …

Dynamic-systems analysis of self-excitation associated with a capacitor-coupled substation (CCS) - induction machine system
The purpose of this thesis is therefore to establish the cause of SSR at the Meru-Petronet system, and other similar systems, and investigate various compensation techniques.

A New Digital Relay for Dispersed Storage and generation (DSG) Units
… bus or load bus during this condition (self-excitation). Self-excitation may lead to severe overvoltages, and may induce undesirable transients in neighoring circuits (low power and control circuits being particularly vulnerable) on the connected network. It can create harmonics that can …

Applied Probabilistic Inference: Model Estimation For Hvac Predictive Controls And All-Weather Perception For Autonomous Vehicles
… dynamics. A simulation study demonstrates self-excitation improves model estimation. Formalization of parameterization, disturbance estimation, and self-excitation routines is shown with an observability analysis. Comparing against a baseline thermostat controller, a Model Predictive …

A microfabricated ElectroQuasiStatic induction turbine-generator
… [mu]W at 235 krpm has been measured under driven excitation of the six phases. Self excited operation was also demonstrated. Under self-excitation, no external drive electronics are required and sufficient power was produced to dimly light four LED's on two of the six phases. This is believed to …

Fluid-structure interaction investigation of a medium-sized heliostat
… modal frequencies, the structure is safe from self-excitation.

Experimental study of a high efficiency step-tunable MW gyrotron oscillator
… in its most efficient regime known as the hard self-excitation regime. This gyrotron operates nominally in the TE22,6,1 mode near the 110 GHz cutoff frequency with an axial field profile that is approximately Gaussian at the steady-state peak voltage. In experiments performed in the smooth …

New Spatio-temporal Hawkes Process Models For Social Good
As more and more datasets with self-exciting properties become available, the demand for robust models that capture contagion across events is also getting stronger. Hawkes processes stand out given their ability to capture a wide range of contagion and self-excitation patterns, including the …
