Granular retrosplenial cortex layer 2/3 generates high frequency oscillation events coupled with hippocampal sharp wave-ripples and Str. LM high gamma
… increases are organized within the local theta oscillations and sequential activation of many place cells creates a map of the environment. Once the animal stops moving and begins consummatory behaviors, such as eating, drinking, or grooming, theta activity diminishes, and large irregular …

Balancing a two-wheeled Segway robot
… acceptable system responses but were subject to high-frequency oscillation. A SISO state feedback controller was also designed, and it was successful in creating stability in simulation and removing the high-frequency oscillation effects. The robot was rebuilt using new parts that better …

Interaction of Variable Axial Load and Shear Effects in RC Bridges
… of the amplitude of axial loading cycles, the frequency of axial loading cycles, and sequencing or phase of axial loading peaks relative to lateral loading. Generally, behavior of the specimens including aspects of strength, stiffness, energy absorption, and failure mode were found to be highly …

Hydrodynamic Impact Analysis and Testing of an Unmanned Aerial Vehicle
… spars. Upon impact, the airframe experienced high-frequency oscillation. Surprisingly, peak accelerations at the wingtips were observed at up to 15g greater than corresponding accelerations at the center of the fuselage.</p>

Observational and evolutionary studies of neutron star X-ray binaries
… lines are inconsistent with the detected high amplitude of the 552 Hz burst oscillations. In Chapter 4 we present our semi-numerical method of evaluating the significance of burst oscillations. With this method, we searched 1187 archived RXTE Type-I X-ray bursts for high frequency …

Investigation of High Frequency Oscillations in Epilepsy Using Computational Intelligence
… delineation of the seizure onset zone (SOZ). High frequency oscillations (HFOs, 80 - 500 Hz) are proposed as putative biomarkers in epilepsy with their potentials of identifying the SOZ, either by augmenting or replacing the current preoperative evaluation modality which requires detained …

Improved Forward Topologies for DC-DC applications with Built-in Input Filter
… including its low cost, circuit simplicity and high efficiency. However, several issues need to be addressed when using the forward converter such as the core reset, the voltage spikes caused by the transformer leakage inductance, and the pulsating input current waveform. The transformer is …
