the first spoken dialogue system developed for the persian language is introduced. this is a ticket reservation system with persian asr and nlu modules. the focus of the paper is on learning the dialogue management module. in this work, real on-line training data are used during the learning process. for on-line learning, the effect of the variations of discount factor (g) on the learning speed...

Reasons behind the failure and success of large-scale information systems projects continue to intrigue researchers. In particular in the airline industry very successful (passenger reservation) systems have been built which have totally changed the competitive arena of the industry. On the cargo side however attempts to implement large-scale community systems have largely failed across the glo...

residue number system (rns) is a non-weighted number system for integer number arithmetic, which is based on the residues of a number to a certain set of numbers called module set. the main characteristics and advantage of residue number system is reducing carry propagation in calculations. the elimination of carry propagation leads to the possibility of maximizing parallel processing and reduc...

This paper proposes a virtual memory management system suitable for interactive continuous media applications. Our virtual memory management system enables continuous media applications to reserve physical memory for allocating pages as soon as possible when the applications require the pages. The system implicitly and incrementally allocates and wires pages used for processing timing critical ...

We wish to provide quality of service (QoS) to scientists who are remotely controlling experiments on singular instruments such as the LBL Advanced Light Source (ALS) or who need to harness heterogeneous and distributed computing resources to perform large-scale computation. To ensure the timely availability of the computing, storage, and networking resources required for data collection and/or...

Distributed continuous media applications that incorporate digital audio and video require predictable response from the operating system and the network. Much recent research in communication networks focuses on providing predictable service at the network level, but current operating systems do not typically provide end-to-end predictability. Our aim is to offer operating system support for p...

Resource reservation needs to accommodate the rapidly growing size and increasing service diversity of the Internet. Recently, hierarchical architectures have been proposed that provide domain-level reservation. However, it is not clear that these proposals can set up and maintain reservations in an efficient and scalable fashion. In this paper, we describe a distributed architecture for inter-...
