this is a case presentation of a 26-year-old woman with a moderate-sized atrial septal secundum defect (17mm) who underwent catheterism, during which an amplatzer septal occluder number 26 was inserted successfully. on the second postoperative day, she deteriorated and a clinical examination showed a typical tamponade. after a percutaneous aspiration of the pericardial cavity and transient impr...

Bow shape has been recognized as an important factor influencing the seakeeping performance and added resistance of ships. This paper presents a numerical comparative study on model ships with ‘X-bow’ wave-piercing monohull in regular head waves using computational fluid dynamics (CFD) software. Different wave heights, wavelengths forward speeds are considered systematic investigation order to ...

In this paper we discuss the real-time simulation of a physical model of a bowed string instrument by means of alternative gestural controllers. We focus on the model's behaviour when submitted to di erent bow strokes performed on a graphical tablet using di erent types transducers. The tablet was chosen because it allows a performer to reproduce most of the basic physical gestures of bow strok...

This latest version of the vBow adds three degrees of freedom to the previous design, allowing for rotational motion across, vertical motion above, and longitudinal motion along the virtual strings, in addition to the original lateral motion of the bow stroke. Like the previous design, this version of the vBow uses servomotors with encoders and cable systems, to sense bow position and provide h...

This paper introduces and evaluates a novel methodology for the estimation of bow pressing force in violin performance, aiming at a reduced intrusiveness while maintaining high accuracy. The technique is based on using a simplified physical model of the hair ribbon deflection, and feeding this model solely with position and orientation measurements of the bow and violin spatial coordinates. The...

The performance of a plug-flow automated aerobic digester used with the compost of the Biodegradable Organic Waste (BOW) from a typical family at its generation rhythm was evaluated. During a 13 month assessment, 179.7 kg of BOW were treated and 106.7 kg of compost were obtained with a C:N ratio of 12 and an average concentration of N of about 2.72%. Additional tests enabled to assess the gener...

Recently, convergence of techniques used in image analysis and video processing has occurred. Many computation and memory intensive image analysis methods have become available for per frame processing of videos due to increased computing power of desktop computers and efficient implementations on multiple cores and graphical processing units (GPUs). As our main contribution in this work, we so...
