Solving Time-Alignment Challenges in Shipboard Non-Intrusive Load Monitoring
… for load identification, all sensors must be time-aligned. This thesis presents several options for time-alignment inherent to the power stream itself, forgoing use of external systems: tracking voltage zero-crossings, matching voltage frequency and amplitude patterns, individual power …

Neural Time Alignment for End-to-End Automatic Speech Recognition Systems
… is spoken in the speech audio, which requires a time alignment between the text and audio to be generated. Conventional ASR systems are based on Hidden Markov Models (HMMs), and use the Viterbi algorithm for generating time alignments for the ASR system output. These time alignments are …

Heavy-duty emissions inventory and prediction
… correlating it was necessary to perform optimal time alignment or shifting of the exhaust emissions data with respect to the instantaneous power produced by the vehicle. Residence time distributions associated with the emissions measurement were addressed by applying a dispersion function to the …

Teaching a robot manipulation skills through demonstration
… and end effector motions are measured through time, and an improved Mean Squared Velocity [MSV] analysis is performed to segment motions into possible goal-directed streams. Further combinatorial selection of subsets of markers allows final episodic boundary selection and time alignment of …

Enhancing spectrum utilization through cooperation and cognition in wireless systems
… novel primitives - adaptive spectrum sensing, time alignment, frequency synchronization, and distributed phase-coherent transmission, that can serve as fundamental building blocks for wireless cognition and cooperation. Finally, we have implemented all four systems described in this …

Evaluation and Standardizing of Phasor Data Concentrators
… the fault, measurements taken at different times throughout the blackout need to be collected and analyzed. With each measurement device having its own time source, time alignment can be a quite tedious and lengthy process. The need for a new time synchronized measurement device has arrived. …

Bayesian Alignment Model for Analysis of LC-MS-based Omic Data
… differences between biological groups. Retention time alignment is one of the most important yet challenging preprocessing steps, in order to ensure that ion intensity measurements among multiple LC-MS runs are comparable. In this dissertation, we propose a Bayesian alignment model (BAM) for …
