The present study comprises steady state, two-dimensional computational investigations performed on NACA 0012 airfoil to analyze the effect of Gurney flap (GF) on airfoil aerodynamics using k-ε RNG turbulence model of FLUENT. Airfoil with GF is analyzed for six different heights from 0.5% to 4% of the chord length, seven positions from 0% to 20% of the chord length from the trailing edge, and s...

The Chord distributed hash table (DHT) is well-known and frequently used to implement peer-to-peer systems. Chord peers find other peers, and access their data, through a ring-shaped pointer structure in a large identifier space. Despite claims of proven correctness, i.e., eventual reachability, formal modeling has shown that the Chord ring-maintenance protocol is not correct under its original...

Efficiently determining the node that stores a data item in a distributed network is an important and challenging problem. This paper describes the motivation and design of the Chord system, a decentralized lookup service that stores key/value pairs for such networks. The Chord protocol takes as input anm-bit identifier (derived by hashing a higher-level applicationspecific key), and returns th...

Syntactic operations in language and music are well established and known to be linked in cognitive and neuroanatomical terms. What remains a matter of debate is whether the notion of syntax also applies to human actions and how those may be linked to syntax in language and music. The present electroencephalography (EEG) study explored syntactic processes during the observation, motor programmi...

OBJECTIVES The objective of this study was to compare electroanatomic mapping for the assessment of myocardial viability with nuclear metabolic imaging using positron emission computed tomography (PET) and with data on functional recovery after successful myocardial revascularization. BACKGROUND Animal experiments and first clinical studies suggested that electroanatomic endocardial mapping i...

In this article, we prove that there exists at least one chord orbit of Hamilton vector field connecting the Legendre submanifold on a given energy stable hypersurface in some symplectic manifolds. Démonstration de existence de chord orbital de hamiltonien en une stable hypersurface dans une variété symplectique. Résumé. Soit Σ une hypersurface close en variété symplectique, Il est de montrer q...

Chord progressions are the building blocks from which tonal music is constructed. The choice of a particular representation for chords has a strong impact on statistical modeling of the dependence between chord symbols and the actual sequences of notes in polyphonic music. Melodic prediction is used in this paper as a benchmark task to evaluate the quality of four chord representations using tw...

This thesis describes research in the computational analysis of harmony in western art music, focussing particularly on improving the accuracy and information-richness of key and chord extraction from digital score data. It is argued that a greater sophistication in automatic harmony analysis is an important contribution to the field of computational musicology. Initial experiments use hidden M...

A 49 year old female presented with severe dyspnoea due to mitral regurgitation. Echocardiography revealed an aberrant mitral valve chord causing severe mitral regurgitation. The aberrant chord extended between the anterior mitral valve leaflet (AMVL) and the atrial septum causing AMVL prolapse. Resection of the aberrant chord and correction of the AMVL using synthetic Gore-Tex sutures was perf...

Harmony is an important component in music. Chord progressions, which represent harmonic changes of music with understandable notations, have been used in popular music and Jazz. This article explores the question of whether a chord progression can be summarized for music retrieval. Various possibilities for chord progression simplification schemes, N-gram construction schemes, and distance fun...
