This paper proposes a unique computational approach to extraction of expressive elements of motion pictures for deriving high level semantics of stories portrayed, thus enabling better video annotation and interpretation systems. This approach, motivated and directed by the existing cinematic conventions known as film grammar, as a first step towards demonstrating its effectiveness, uses the at...

We present an approach to phrase segmentation that starts with an expressive music performance. Previous research has shown that phrases are delineated by tempo speedups and slowdowns. We propose a dynamic programming algorithm for extracting phrases from tempo information. We test two hypotheses for modeling phrase tempo shapes: a quadratic model, and a spline curve. We test the two models on ...

This paper describes a real-time system for rhythm manipulation of polyphonic audio signals. A rhythm analysis module extracts information of tempo and beat location. Based on this rhythm information, we apply different transformations: Tempo, Swing, Meter and Accent . This type of manipulation is generally referred as Content-based transformations. We address characteristics of the analysis an...

In this study, the change in the synchronization between heartbeat and music was investigated. The phenomena of the synchronization between human heartbeat and musical tempo has been reported in several previous studies, however, it has not yet been fully investigated including the effect of changing the tempo of musical piece on the synchronization. In the experiment, the subjects were exposed...

INTRODUCTION Culture methods used to determine Escherichia coli levels in food products are time consuming and labor intensive. The TEMPO system and reagents have been developed to replace plate and tube counting methods. In this study the TEMPO system has been used to compare the performance of the TEMPO EC test for the enumeration of E. coli in food products to the ISO 16649-2 plate count met...

In this paper, we present a novel set of tempo-related audio features for applications in audio retrieval. As opposed to existing feature sets commonly used in the retrieval domain which mainly focus on local spectral characteristics of the audio signal, our features capture its local temporal behaviour w.r.t. tempo, rhythm, and meter. As a key component to obtaining a high level of feature rob...

This paper addresses the question how music information retrieval techniques originally developed to process audio recordings can be adapted for the analysis of corresponding brain activity data. In particular, we conducted a case study applying beat tracking techniques to extract the tempo from electroencephalography (EEG) recordings obtained from people listening to music stimuli. We point ou...

Tempo, micro time and time signature are basic rhythmic features for a wide range of music. Their automated extraction from music is needed for a number of applications, e.g. automatic transcription and music information retrieval systems, authoring tools, entertainment applications, musicological analysis or educational purposes. The presented analysis procedure estimates tempo, micro time and...

A trombose de stent (TS) é uma grande preocupação na era dos stents farmacológicos (SF). Há vários relatos de trombose de stent até cinco anos após sua implantação. Relatamos o caso de uma paciente de 68 anos com TS tardia, que se apresentou como infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST) após interrupção da terapia antiplaquetária, oito anos depois da implantaç...

RESUMO: o presente trabalho examina a hipótese de eficiência de mercado estimando um modelo de series temporais com coeficientes que variam no tempo. A metodologia utilizada foi a do Filtro de Kalman para um modelo autoregressivo e de média móvel (ARMA) com erros modelados com heteroscedasticidade condicional autoregressiva generalizada (GARCH). O modelo foi estimado pelo método da máxima veros...
