Computational Auditory Scene Analysis (CASA) has been the focus in recent literature for speech separation from monaural mixtures. The performance of current CASA systems on voiced speech separation strictly depends on the robustness of the algorithm used for pitch frequency estimation. We propose a new system that estimates pitch (frequency) range of a target utterance and separates voiced por...

En una casa de subastas, compradores y vendedores se coordinan para intercambiar bienes siguiendo un procedimiento sumamente estructurado y aparentemente sencillo. Esas convenciones de coordinaci on han evolucionado a lo largo de siglos y actualmente se utilizan dentro de instituciones comerciales para intercambiar bienes y servicios de una gran diversidad. En este trabajo tomamos una casa de s...

A lot of effort has been made in Computational Auditory Scene Analysis (CASA) to segregate target speech from monaural mixtures. Based on the principle of CASA, this article proposes an improved algorithm for monaural speech segregation. To extract the energy feature more accurately, the proposed algorithm improves the threshold selection for response energy in initial segmentation stage. Since...

An Hochschulen ist heute eine hochgradig heterogene IT-Landschaft mit Diensten und Web-Anwendungen etabliert. Durch die gewachsenen Strukturen an vielen Fakultäten und die häufig dezentral verwalteten Anwendungen ergibt sich für die Studierenden die Notwendigkeit, eine Vielzahl von Diensten zu kennen und regelmäßig aufzusuchen. Das in diesem Beitrag vorgestellte CASA-Konzept (Context-Aware Serv...

Motile porcine sperms adhere to hydrophilic materials such as glass and plastics. The adsorption of sperms to a hydrophobic poly(dimethylsiloxane) (PDMS) membrane is less compared with that to glass. We investigated the linear velocity (LV) and amplitude of lateral head displacement (ALHD) of motile porcine sperm on glass and PDMS preparations using computer-assisted sperm analysis (CASA). Sign...

This paper presents the latest developments of the Public Sound Objects (PSOs) system, an experimental framework to implement and test new concepts for Networked Music. The project of a Public interactive installation using the PSOs system was commissioned in 2007 by Casa da Musica, the main concert hall space in Porto. It resulted in a distributed musical structure with up to ten interactive p...

In boreal conifers, maximum latewood density (MXD) of annual rings varies in response to warm-season temperatures. Vegetation productivity can be estimated using the Normalized-DiŒerence Vegetation Index (NDVI) calculated from satellite sensor data. Ground measurements related to productivity are required in order to evaluate these estimates. MXD from three boreal sites was compared with estima...

One of the broad goals of research in computational auditory scene analysis (CASA) is to create computer systems that can learn to recognize sound sources in a complex auditory environment. In this paper, a set of acoustic features is proposed that relate to the physical properties of sound-producing objects. In particular, a set of orchestral musical instrument sounds is presented as represent...
