    The body's immune system is impressively good at coping with external and internal errors, usually known as bacteria and viruses. The body is able to distinguish the haemoglobin found in blood from the insulin secreted by the pancreas from the vitreous humor contained in the eye from everything else. It must manage to repel innumerable different kinds of invading organisms and yet not attack the b... View full abstract»

    The Komodo project concerns the handling of multiple real-time events by Java threads that are supported by a multithreaded Java microcontroller. The architecture of the processor core and resulting implications are considered. The use of thread-based event handling is introduced and explained in combination with an Automatic Guided Vehicle (AGV) application. The advantages of thread-based event h... View full abstract»

    Fault tolerance in embedded distributed systems requires flexibility. Solutions should be based on pre-built and reusable elements, customisable for different applications and portable to different platforms. To this end, a framework is presented, consisting of a user library, a control backbone and a high-level description language (RL). The user library contains basic functions for fault toleran...

    Digital waveguide models have been used successfully as a partial alternative to time domain models based on the wave equation in the fields of musical acoustics and sound synthesis. 2D and 3D rectilinear topologies of unit delay waveguides have been used to model plates, membranes and acoustic spaces. This paper introduces a more accurate model of wave propagation using a mesh based on a triangul... View full abstract»

    Network-centric computing aims to solve the problems associated with traditional client/server systems, namely the high performance requirements, and costly maintenance of, the computing resources. With the network-centric model, applications are stored on servers and downloaded to clients as required, where they are then executed locally. User data is saved back to the remote server-local user da... View full abstract»

  • Distance learning support for teaching musical temperament

    Publication Year: 1999, Page(s):42 - 45 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (36 KB)

    When teaching aspects of music technology to students with mixed musical backgrounds, some issues are harder to back up with listening examples than others to reinforce lecture material. A particular topic that is important for a strong basic understanding of both music history and potential for electronic instruments is that of tuning systems. Whilst it is easy to point out that modern keyboard i... View full abstract»

  • The chorus effect revisited-experiments in frequency-domain analysis and simulation of ensemble sounds

    The so-called `chorus' or `ensemble' effect is interesting both musically and perceptually. It is usually imitated in effect devices using slowly varying time shifts, giving the impression of rotating speakers rather than of an ensemble. M. Dolson (1983) found that the quasi-random amplitude modulation of beating partials alone can cue the perception of ensemble. The small changes in frequency, he... View full abstract»

    General purpose motion estimation algorithms do not exploit the information available about the fixed characteristics of the video sequences in specific application domains. In this paper we propose to take advantage of such information to develop efficient video compression algorithms and we apply the proposed approach to the highway monitoring application domain. The proposed approach allows als... View full abstract»

    This paper presents experimental results of an investigation to efficiently exploit PVM communication on Network of Workstations (NoW) over ATM networks. Test results show that a better exploitation of ATM LAN bandwidth can be gained by tuning few parameters, both at PVM application program interface and PVM implementation level, such as PVM packet fragment size and TCP socket buffer size.

  • A parallel processing system for polyphonic singing synthesis

    Publication Year: 1999, Page(s):70 - 74 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (80 KB)

    A synthesiser has been designed for polyphonic (multi-voice) singing synthesis. Singing synthesis requires frequent updating of parameters to achieve a natural output sound. These parameters include fundamental frequency, formant frequencies, formant bandwidths, and voice source parameters (such as Open Quotient). The synthesis engine is controlled using a script and a graphical user interface. Th... View full abstract»

    In this paper we present an improved hard acknowledgement deadline protocol in real-time remote procedure call (RT-RPC). Current RT-RPC protocol asks services and waits until the deadline of result. M. Dao and Kwei-Jay Lin (1991) extended RT-RPC by adding hard acknowledgement deadline and got considerable result, to give more time to client recovering error etc. We improved that hard acknowledgeme...

    We propose a mobile-agent parallel processing framework that uses multiple Java mobile agents, each one of which utilizes multithreading. A mobile agent can travel at any Web site to perform its tasks. We also introduce the concept of task handlers, which are Java objects capable of implementing a particular task of the target application. TaskHandlers are dynamically assigned to mobile agents. We... View full abstract»

    Existing audio tools handle the increasing amount of computer audio data inadequately. The typical tape-recorder paradigm for audio interfaces is inflexible and time consuming, especially for large data sets. On the other hand, completely automatic audio analysis and annotation is impossible using current techniques. Alternative solutions are semi-automatic user interfaces that let users interact ...

    Sequential network simulation is a high time-consuming application, and with the emergence of global multihop networks and gigabit-per-second links is becoming a non-affordable problem with traditional simulations. New techniques for the acceleration of these simulations based on other hardware architectures are required. Previous approaches to simulation acceleration are based on parallel computi...
