Los restos momificados y sus artefactos asociados son frágiles y vulnerables a varios tipos de deterioro, incluyendo los factores que resultan de las condiciones ambientales, el daño físico y el daño causado por intentos anteriores o inapropiados de conservación. Este informe considerará los beneficios y desventajas de los métodos de conservación mediante los cuales la mayor parte del deterioro...

ResumenLa sincronización multimedia ha sido un área de investigación clave desde los inicios de los sistemas multimedia. En este artículo se ofrecen una visión general y un análisis sobre el impacto de varios parámetros de QoS en diferentes aspectos de la QoE, desde el punto de vista de la sincronización multimedia. En primer lugar, se presentan los diferentes tipos de sincronización multimedia...

In the past, large external filters and shielded cables were the accepted ways to address EMI/EMC (electromagnetic interference or electromagnetic compatibility) in audio/video products. These methods added cost, adversely affected performance, and increased the size of the end product. As these products have decreased in size and evolved into the modern audio/video players, the solutions have ...

We present a preliminary study examining non-visual menu navigation in terms of task completion times and cognitive workload. We asked 12 participants to locate items on menus presented using visual, audio-only and audio-tactile displays on a touch screen mobile device and found that users were significantly slower in locating an item on a menu when using an audio-tactile menu display. This dif...

Microfluidic paper-based analytical devices (microPADs) are a new class of point-of-care diagnostic devices that are inexpensive, easy to use, and designed specifically for use in developing countries. (To listen to a podcast about this feature, please go to the Analytical Chemistry multimedia page at pubs.acs.org/page/ancham/audio/index.html.).

Although Cloud Computing remains de-facto solution for IoT data processing, Edge Computing (EC) has started to gain its ground. EC systems are closer to devices generating various data types (audio, video, text etc.) and have capabilities to provide quick data validation and analysis. This paper explores one such application of EC for audio analysis in road side assistance services. A noise can...

Portable multimedia player (PMP) devices have been gaining in its popularity with the emerging digital convergence of data, video, audio, etc. Since the PMP devices are typically equipped with DSP, bigger display, and a hard disk, efficient power management has become more crucial than the other portable devices. This paper establishes a hardware/softwarebased power measurement system based on ...

Present day personal and home hi-fi products are designed to work independently. In the near future these devices will have increased networking capabilities. This connectivity will enable a large number of audio/video (A/V) sources such as CD’s, DVD’s, digital libraries and internet broadcasts to be linked with A/V sinks such as active loudspeakers, recorders and home internet gateways. This p...

In this paper we propose a generic framework for efficient retrieval of audiovisual media based on its audio content. This framework is implemented in a client-server architecture where the client application is developed in Java to be platform independent whereas the server application is implemented for the PC platform. The client application adapts to the characteristics of the mobile device...

This article presents a novel closed loop control architecture based on audio channels of several types of computing devices, such as mobile phones and tablet computers, but not restricted to them. The communication is based on an audio interface that relies on the exchange of audio tones, allowing sensors to be read and actuators to be controlled. As an application example, the presented techn...
