The Past

Aiming to explore the diverse nature of sound and image, thereby establishing a bridge with the symbiotic creation of sensations and emotions, this chapter intends to present the development and the construction of a proposal for the confluence between materiality and immateriality in site-specific sound and visual performances. Using as a focal point sound and visual narratives, the author tries to look beyond space and time and create a representative atmosphere of sense of place, attempting to understand the past and sketching new configurations for the (re)presentation of identity, guiding the audience through a journey of perceptual experiences, using field recordings, ambient electronic music, and videos. This chapter also presents the development of an experimental approach, based on a real-time sound and visual performance, and some critical forms of expression and communication that relate or incorporate sound and image, articulating concerns about their aesthetic experience and communicative functionality.

Musique Concrete

With the end of World War II came the rebirth of European radio. Government stations in both France and Germany established experimental studios for research, from which arose a new kind of music, “electronic music.” The station in France, Office de Radiodiffusion Télevision Française (ORTF), was directed by the engineer/composer Pierre Schaeffer and his partner, Pierre Henry, who called their musical creations musique concrète. In Germany the Westdeutscher Rundfunk (WDR) studio produced music through the process of “synthesis.” This chapter will explain the difference between the two approaches used to create electronic music with examples from the percussion solo and ensemble repertoire. Early experiments using wire recorders, test records, and tape recorders by composers Halim El-Dabh, John Cage, and Edgard Varèse precede the major electronic works of Karlheinz Stockhausen, Mario Davidovsky, and the American composer Stephen Everett, whose use of computers in “real time” brings the reader into the next century.

A challenge is always presented when attempting to measure the pain an individual patient experiences. Unfortunately, present technologies rely nearly exclusively on subjective techniques. Using these current techniques, a physician may use a manually operated algometer and a series of questionnaires to gauge an individual patient’s pain scale. Unfortunately these devices and test methods have been suggested to introduce error due to variability and inconsistent testing methods. Some studies have shown large variability, while others have shown minimal variability, both between patients and within the same patient during multiple testing sessions. Recent studies have also shown a lack of correlation between pain threshold and pain tolerance in pain sensitivity tests. Hand-held algometer devices can be difficult to maintain consistent application rates over multiple test periods, possibly adding to widespread variability. Furthermore, there are limited test results that correlate pain ratings with biological measures in real time. The computer-controlled pressure algometer described is not hand-held or dependent on significant examiner input. This new device is capable of recording electrocardiograph (ECG), blood pressure (BP), pressure pain threshold (PPT), and pressure pain tolerance (PPTol) in real time. One major goal is the capability of correlating pain stimuli with algometer pressure, heart rate, and blood pressure. If a predictable correlation between vital signs and pain could be established, significant gains in the understanding of pain could result. Better understanding of pain will ultimately lead to improvements in treatment and diagnosis of pain conditions, helping patients and physicians alike.

The analysis of the ship layout from the point of view of safe and orderly evacuation represents an important step in ship design, which can be carried out through agent-based evacuation simulation tools, typically run in batch mode. Introducing the possibility for humans to interactively participate in a simulated evacuation process together with computer-controlled agents can open a series of interesting possibilities for design, research and development. To this aim, this article presents the development of a validated agent-based evacuation simulation tool which allows real-time human participation through immersive virtual reality. The main characteristics of the underlying social-force-based modelling technique are described. The tool is verified and validated by making reference to International Maritime Organization test cases, experimental data and FDS + Evac simulations. The first approach for supporting real-time human participation is then presented. An initial experiment embedding immersive virtual reality human participation is described, together with outcomes regarding comparisons between human-controlled avatars and computer-controlled agents. Results from this initial testing are encouraging in pursuing the use of virtual reality as a tool to obtain information on human behaviour during evacuation.

In this article, an analysis of the piece Desdobramentos do contínuo for violoncello and live-electronics is addressed concerning instrumental extended techniques, electroacoustic tape sounds, real-time processing, and their interaction. This is part of a broad research about the computer-aided musical analysis of electroacoustic mu- sic. The objective of the analysis of this piece is to understand the spectral activity of the emergent sound structures, in terms of which events produce huge timbre variations, and to identify timbre subtle nuances that are not percep- tible on a first listen of the work. We conclude comparing the analyses results to the compositional hypotheses pre- sented in the initial sections.

Traditional optical music recognition (OMR) is an important technology that automatically recognizes scanned paper music sheets. In this study, traditional OMR is combined with robotics, and a real-time OMR system for a dulcimer musical robot is proposed. This system gives the musical robot a stronger ability to perceive and understand music. The proposed OMR system can read music scores, and the recognized information is converted into a standard electronic music file for the dulcimer musical robot, thus achieving real-time performance. During the recognition steps, we treat note groups and isolated notes separately. Specially structured note groups are identified by primitive decomposition and structural analysis. The note groups are decomposed into three fundamental elements: note stem, note head, and note beams. Isolated music symbols are recognized based on shape model descriptors. We conduct tests on real pictures taken live by a camera. The tests show that the proposed method has a higher recognition rate.

For time deterministic control, manufacturers and system designers of computer controlled machinery use real-time based systems to satisfy stringent requirements. Standard real-time systems contain built in kernel modules and often some type of user interface written in C. With a large multidimensional system spanning many smaller objective systems, it is hard for specialists to access real-time controlled objects on the spot. Making modifications to the user interface may require a slew of compilation and linking. This article presents an Interpretive Real-Time Linux Interface, which seamlessly integrates C/C++ applications using a C/C++ interpreter. Running the application interpretively makes the interface insensitive to user customization and product upgrading. An example of an insensitive interface is given in which a CGI web based user interface written in C has been implemented allowing users to control the frequency output of a speaker through a real-time Linux system from the web.
