Playback

"I Don't Get Music Technology" is the second in the "Whaaaaaaaaat" series, and is a handbook for educators, musicians, or general readers wishing to make sense out of technology, every aspect of which addresses three ideas — physics, transformation, and aesthetics. In following this book, take, read, and understand each topic. This is not a recipe book or a buying guide for microphones or camcorders. It’s principles, background, history, and commonalities. (Book is also available in print form from online booksellers.)

Using a basic model, this paper explains how to make a wooden device for the reproduction of pottery vessels in plaster, using
metallic templates in which its profiles have been cut (modelling board). It gives the measurements of each of the device's components
and the materials to be used. It describes the different steps in the reproduction process. Its real use is not reproduction, however, but as
an aid for the restoration of archaeological pottery. Finally the paper comments on the few different models that have been published.

Recent progress of Visual Sensor Networks (VSNs) has been resulted from great development in cameras techniques that has been enabled the development of single chip camera modules that could easily be embedded into inexpensive transceivers. The interconnection of multimedia sources with inexpensive communication devices has enhanced research in the networking of visual sensors. Due to the large size of the multimedia that captures by visual sensor node, video streams require high bandwidth for a multi-hop wireless environment. So the main two factors influencing in design of transport protocol for visual sensor network are reliability and real time.
This paper proposes Reliable Real Time Video Transport
Protocol (RRVTP) that attempts to solve the reliability and
real-time problems by sending captured video in real-time and
guarantees the delivery of all corrupted/dropped frames for
reliable storage (playback).

This study examines how friends in their mid-twenties appropriate texts from online memes to serve particular functions in their everyday face-to-face conversations. Speakers use references to the "Strong independent black woman" and "Skipping leg day" online memes, both of which
mock certain cultural stereotypes, to shift the epistemic territories of conversations when they encounter interactional dilemmas due to topic attrition and/or epistemic imbalances. These epistemic shifts simultaneously shift the frame of the talk to humorous play frames that allow for different structures of participation and conversational involvement. This study contributes to understanding how epistemic frame shifts relying on intertextual ties to new media can resolve interactional dilemmas in everyday conversation, which is ultimately conducive to managing group epistemics and identity.

contributed by JACQUES M.E. VIELLIARD* Playback of bird songs is a useful technique for species detection; however, this method is usually not stan-dardized. We tested playback efficiency for five Atlantic Forest birds (White-browed Warbler Basileuterus leucoblepharus, Giant Antshrike Batara cinerea, Swallow-tailed Manakin Chiroxiphia caudata, White-shouldered Fire-eye Pyriglena leucoptera and Surucua Trogon Trogon surrucura) for different time of the day, season of the year and species abundance at the Morro Grande Forest Reserve (South-eastern Brazil) and at thirteen forest fragments in a nearby landscape. Vocalizations were broadcasted monthly at sunrise, noon and sunset, during one year. For B. leucoblepharus, C. caudata and T. surrucura, sunrise and noon were more efficient than sunset. Batara cinerea presented higher efficiency from July to October. Playback expanded the favourable period for avifaunal surveys in tropical forest, usually restricted to early morning in the bree...

TCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Biológicas. Biologia.Os peixes podem ser solitários ou viver em cardumes mais ou menos hierarquizados. Neste ultimo caso, existe uma necessidade maior de comunicação entre os indivíduos e esta comunicação pode se dar através de diversos canais, entre eles o canal acústico. Os ciclídeos, como Metriaclima zebra, produzem sons no contexto da reprodução e de interações agonísticas, porém a variação diária dessa produção sonora é ainda pouco estudada. O objetivo desse estudo foi, num primeiro momento, descrever, em laboratório, as atividades comportamentais e a produção sonora ao longo de um nictêmero para Metriaclima zebra. Filmagens de longa duração (3-4 dias) de dois grupos (primeiro grupo: 22 jovens e adultos; segundo grupo: 12 adultos machos), foram realizadas sob um regime luminoso artificial de 8h de dia (165lx) e 12h de noite (0lx), intercalados com 2h e 2h de crepúsculo (3,2lx). Foram analisadas 72 horas...

El live coding, live cinema o distintos tipos de performance audiovisual desarrollados con sistemas digitales se proponen como nuevas formas de creación basada en la improvisación libre. Esto implica el uso de herramientas digitales que permiten la práctica performativa ante la audiencia, software y sistemas de programación audiovisual que se han desarrollado  recientemente para este propósito. Estas prácticas tratan de mostrar al público los mecanismos de construcción de contenidos que subyacen en los sistemas digitales, sin ocultar los procesos técnicos que suelen quedar reservados al taller del creador. El deseo de lanzarse a una creación desde cero mostrando a la audiencia todo el desarrollo del proceso se contradice
con la necesidad de establecer mecanismos seguros que resuelvan las dificultades tecnológicas. Utilizaremos la imagen del lienzo en blanco, con su problemática sobre el bloqueo creativo, para analizar estas prácticas artísticas en los nuevos medios y evidenciar las contradicciones y ficciones que implica este modelo de creación basado en la improvisación libre desde la nada a vista del público.
