Robust Speaker Diarization for Single Channel Recorded Meetings
This thesis describes research into speaker diarization for recorded meetings. It explores the algorithms and the implementation of an off-line speaker segmentation and clustering system for meetings that have been recorded using one microphone. Speaker diarization is defined as a process of …

Understanding The Single Channel Behavior Of Glua3 Receptors
… as more information relating LBD closure to channel activation began to surface, it became clear the relationship was not as direct as previously thought. The studies in this dissertation look at the single channel behavior of GluA3 receptors and supply new evidence that both full and partial …

Development of a Single-Channel Direction Finding Algorithm
… on the development and implementation of a novel single-channel direction finding system based on the differential phase of the target signal received by a uniform circular antenna array with a commutative switch. The algorithm is called the PLL DF Method and differs from older single-channel DF …

SINGLE-CHANNEL REAL-TIME DROWSINESS DETECTION BASED ON ELECTROENCEPHALOGRAPHY
… real-time drowsiness detection system based on a single-channel electroencephalography (EEG). Towards that goal, we introduced three main contribution proposed in this thesis: (1) a real-time drowsiness detection algorithm based on EEG suitable for portable applications with low computational …

The Augmented Geometrically Spaced Transform : applications of the single channel frequency estimator
… matrix, a spectral envelope is computed using a Single Channel Frequency Estimator (SCFE). The core invention of the thesis is the algorithm for the SCFE, which computes spectral envelopes with maximally high definition in a computationally efficient manner. A bank of SCFEs is assembled into a …

An iterative, residual-based approach to unsupervised musical source separation in single-channel mixtures
… source signals from musical mixtures when only a single mixture channel is available. Source separation is the process by which signals that correspond to distinct sources are identified in a signal mixture and extracted from it. Producing multiple entities from a single one is an extremely …

Single channel characterisation of a calcium-selective channel from wheat roots / by Miguel Alfonso Pinenos.
Provides evidence for a specific, regulated, high affinity mechanism for entry of calcium and other divalent cations into the roots of wheat.

DM EMI Noise Analysis for Single Channel and Interleaved Boost PFC in Critical Conduction Mode
… the worst case analysis can be extended to 2-channel interleaved CRM PFC and some interesting characteristics can be observed. For example, the great EMI performance improvement through ripple current cancellation in traditional constant frequency PFC by using interleaving techniques will not …

Analysis and Implementation of a Novel Single Channel Direction Finding Algorithm on a Software Radio Platform
… multiple receivers are impractical. Thus, single channel techniques are of interest, particularly in mobile scenarios. Although the amount of existing research for single channel DF is considerably less than for multi-channel direction finding, single channel direction finding techniques …

Investigation of pressure-tube and calandria-tube deformation following a single channel blockage event in ACR-700
… is the complete coolant flow blockage of a single PT. The flow is not monitored within each individual PT, thus during the early stages of this accident the reactor remains at full power and full pressure, resulting in rapid coolant boil-off and fuel overheating. Melting of the Zircaloy …

Single-Channel Studies of Agonist Interactions With the Neurotransmitter-Binding and Pore Domains of the Muscle Nicotinic Acetylcholine Receptor
… acetylcholine receptor, a ligand-gated ion channel, is activated by a variety of naturally occurring and synthetic ligands. The overall 'response' elicited by any ligand of the nicotinic receptor is not only a consequence of its binding to the extracellular neurotransmitter-binding domain, …

Heat and Mass Transfer in Reactor Core During a Loca-Single Channel Analysis (Mixed Convection, Numerical, Flow, Thermal-Hydraulics)
Ability to predict the scenario following a loss-of-coolant accident (LOCA) is of central importance in the safety analysis of water reactors. During LOCA, the reactor core is uncovered and the residual water inventory is boiled off by fission products decay heating. For the Three Mile Island …

Poly(ethylene glycol)-based open-channel blockers for the acetylcholine receptor : mechanistic and structure-function studies at the single-channel level
Ion channels are essential mediators in nervous signaling pathways. Because hyperactivation of ion channels can lead to pathological disorders such as congenital myasthenic syndromes and neurodegeneration, channel inhibitors are potentially useful in the treatment of channel-associated diseases. …

Single channel studies on the modulation of connexin hemichannels by Cx43 targeting peptides and cytoplasmic Ca2+ in the context of heart disease
In vertebrates, connexin hemichannels in the plasma membrane dock head-to-head with their counterparts in adjacent cells to form gap junction channels, allowing direct cell-cell transfer of electric and chemical/metabolic signals. Each hemichannel comprises a hexamer of connexin proteins which …

Single-Microphone Speech Dereverberation: Modulation Domain Processing and Quality Assessment
… over the past few years. Although multiple channel dereverberation methods provide some improvements in speech quality/ intelligibility, single-channel dereverberation remains an open challenge. Two types of advanced single-channel dereverberation methods, namely acoustic domain spectral …

Multi-channel coded-aperture photography
This thesis describes the multi-channel coded-aperture photography, a modified camera system that can extract an all-focus image of the scene along with a depth estimate over the scene. The modification consists of inserting a set of patterned color filters into the aperture of the camera lens. …
