Design and Performance Engineering

Profile article. Jean-Guy Lecat's guiding hand can be gleaned in the construction of Teatro Azul de Almada in Lisbon, the building of the New Young Vic in London, the major renovation of the historic Abbey Theatre in Dublin, the remaking of the Naves del Antiguo Matadero into a performing arts space in Madrid — and now the construction of Theatre for a New Audience's new home at the Polonsky Shakespeare Center in Brooklyn.

Prior to the Polonsky Shakespeare Center, Lecat was known in New York for transforming a literally crumbling 1904 space, two blocks from the Brooklyn Academy of Music into the BAM Harvey Theater. The Harvey was built specifically to house Peter Brook’s nine-hour production of "The Mahabharata" and his subsequent "The Cherry Orchard." Lecat's hand also hewed Lincoln Center's Vivian Beaumont Theatre and La MaMa's Ellen Stewart Theatre (formerly the Annex).

The functionality of the wireless application protocol (WAP) dependent nomadic devices can be enhanced using techniques for the reconfiguration of such devices in the mobile environment, either individually or en mass. For example, a system that enables the hand-held devices of selected personnel at a disaster site to be automatically adapted for specifically directed emergency WAP communications is highly beneficial. In this paper we present a method for the provision of configuration settings over the wireless application protocol using the GSM short messages system (SMS). Discussion of implementation of wireless datagram protocol, wireless session protocol and wireless application environment layers is included. Data for push operation via an SMS gateway is presented that demonstrates increasing popularity amongst users.

This short document explains the ethos, and current interests of the IFTR Theatre Architecture Working Group. Calls for papers appear via listservs in November/December each year. Please contact the convenors for further information: [email protected] and [email protected]

En la segunda mitad del siglo XX, la cibernética y el pensamiento sistémico, proporcionaron un nuevo marco teórico para el diseño; a partir de estos nuevos conocimientos, que se generaron después de la aparición del ordenador, se empezó a desarrollar un nuevo modo de pensar el diseño, definido como Performance-based design (PBD). Mediante la aplicación de métodos analíticos, y con el apoyo de la tecnología informática, el PBD tiene por objeto facilitar una metodología que simula los efectos de diferentes soluciones de diseño, con el fin de mejorar la eficacia del proceso de toma de decisiones, es decir el diseño .

Among the IPv6 tunneling techniques, this paper compares the tunneling overhead of two recent IPv6 tunneling techniques: Teredo, and ISATAP. These protocols were implemented on real test bed setup, on Microsoft Windows (MS Windows XP and MS Windows Server 2003) and Linux operating systems. Five to six devices were used to setup the whole test bed. Each protocol was then implemented on the setup using specific configuration commands. UDP audio streaming, video streaming and ICMP-ping traffic was run. Four different runs of traffic were routed over the setup for each protocol. The average of the data was taken to generate graphs and final results. The comparison of tunneled traffic of these techniques has been performed through certain parameters, namely: tunneling overhead, tunnel setup delay, query delay, and auxiliary devices required.

Coexistence of IPv4 and IPv6 bears problem of incompatibility, as IPv6 and IPv4 headers are different from each other. To counter this problem, three solutions are possible: a) making every device dual stack, b) translation, c) tunneling. Tunneling stands out as the best possible solution.

Optical burst switching (OBS) is a promising method for data transfer in photonic networks based on a Wavelength Division Multiplexing (WDM) technology. Transmission control protocol (TCP)-based applications generate the majority of data traffic in the Internet; thus, understanding and improving the performance of TCP over OBS networks is critical. In this paper, we develop a novel burstdropping strategy to improve the quality of service provided by TCP over OBS networks. Our approach relies on random-segment dropping according to the capacity of a special optical component, called the optical virtual memory, which is used for buffering purposes within the optical switches. The core node predicts incipient congestion by computing the average blocking duration in the optical virtual memories. When this size exceeds a threshold, segments are randomly dropped. Simulation results show that the proposed method performs better than common techniques in terms of burst loss probability and transmission delay.
