An accurate system matrix is required for quantitative proton CT (pCT) image reconstruction with iterative projection algorithms. The system matrix is composed of chord lengths of individual proton path intersections with reconstruction pixels. In previous work, reconstructions were performed assuming constant intersection chord lengths, which led to systematic errors of the reconstructed proto...

A number of studies have indicated that relaxing and pleasant melodies are useful for the treatment of patients with psychiatric disorders, including schizophrenia, depression, and dementia. However, few studies have investigated what constitutive elements of the music had an effect on brain activity. As Canon chord progression is one of critical elements for pleasant melodies, we sought to exa...

Distributed Hash Tables (DHT) are mechanisms used to locate data in P2P and Grid computing. Early DHT schemes, while providing lookups with optimal or near optimal efficiency at the overlay level, tend to neglect efficiency at the physical level. Although one may extend a DHT scheme by simply adding additional nodes in routing tables to provide extra locality choices, we note that there are int...

The present study investigates the effect of a change in syntactic-like musical function on event-related brain potentials (ERPs). Eight-chord piano sequences were presented to musically expert and novice listeners. Instructed to watch a movie and to ignore the musical sequences, the participants had to react when a chord was played with a different instrument than the piano. Participants were ...

Peer-to-peer (P2P) is a class of network applications in which each workstation has equivalent capabilities and responsibilities and communications are potentially symmetric. P2P computing takes advantage of existing computing power, computer storage, and networking connectivity, available at the edges of the Internet, by allowing users to leverage their collective power to the benefit of all. ...

This document describes a submission to the Music Information Retrieval Evaluation eXchange in the Audio Chord Recognition task. A set of chroma vectors representing the pitch content of the audio file over time is extracted. From these observations the chord progression is then estimated using hidden Markov models. The system takes into account the presence of higher harmonics of pitch notes a...

The processing of a target chord depends on the previous musical context in which it has appeared. This harmonic priming effect occurs for ®ne syntactic-like changes in context and is observed irrespective of the extent of participants' musical expertise (Bigand & Pineau, Perception and Psychophysics, 59 (1997) 1098). The present study investigates how the harmonic context in ̄uences the process...

Chord is one of the simplest peer-to-peer systems that addresses the issue of eecient data location. Despite its simplicity, one of its main limitations remains the asymmetric organization of its routing. This leads to problems like inability to make in-place notiications of routing entry changes, and incapacity to support symmetric applications and to eeciently exploit network proximity. As a ...

Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

This paper presents a multi-modal approach to automatically identifying guitar chords using audio and video of the performer. Chord identification is typically performed by analyzing the audio, using a chroma based feature to extract pitch class information, then identifying the chord with the appropriate label. Even if this method proves perfectly accurate, stringed instruments add extra ambig...
