Augmented Transition Networks As Semantic Models For Multibaedia Presentations, Multimedia Database Sear.Ching, And Multimedia Browsing, Shu-Ching Chen, R. L. Kashyap

Department of Electrical and Computer Engineering Technical Reports

As more information sources become available in multimedia systems, the development of abstract semantic models for video, audio, text, and image data becomes very important. An abstract semantic model has two requirements. First, it should be rich enolugh to provide a friendly interface of multimedia presentation synchronization schedules to tlie users. Second, it should be a good programming data structure for implementation to control multimedia playback. An abstract semantic model based on an augmented transition network (ATN) is presented. Tlle inputs for ATNs are modeled by multimedia input strings. Multimedia input strings provide an efficient means for iconic indexing of …

Sample-Adaptive Coding Scheme (Sacs): A Structurally Constrained Vector Quantizer, Dong Sik Kim, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

In this paper, we propose a novel feed-forward adaptive coding scheme called SACS (sample adaptive coding scheme) for the lossy compression of a discrete-time memoryless stationary source. SACS is based on a concept of adaptive quantization to the varying samples of the source and is very different from traditional adaptation techniques for non-stationary sources. SACS quantizes each solirce sample using a sequence of quantizers. Even when using scalar quantization in SACS, we can ach.ieve performance comparablse to vector quantization (with the complexity still of the order of scalar quantization). We also show tihat important lattice based vector quantizers can be …

Disaggregating Labor Payments By Skill Level In Gtap, Jing Liu, Nico Van Leeuwen, Tri Thanh Vo, Rod Tyers, Thomas Hertel

GTAP Technical Papers Archive

This paper outlines an approach to disaggregating labor payments in the GTAP, global economic data base. The split between low- and high-skilled labor is based on occupational data. High-skilled labor is assumed to consist of managers, administrators, professionals, and para-professionals.

Data are gathered on this occupational split, by sector, in fifteen different economies, and these are mapped to GTAP sectors. Regression analysis shows a systematic relationship between GDP per capita and the national stock of tertiary and secondary educated labor on the one hand, and the sectoral labor payments split on the other.

This model is used to predict labor …

Jitter Control And Dynamic Resource Management For Multimedia Communication Over Broadband Network, Ahmed Bashandy, Edwin Chong, Arif Ghafoor

Department of Electrical and Computer Engineering Technical Reports

Due to the isochronous nature of multimedia streams, jitter management; represents a major challenge to synchronized and timely presentation of multimedia documents. For controlling jitter, we propose the Initial Delay Regulator (IDR). This regulator is based on a network model which abstracts jitter parameters inside a data network. As a result of employing such a regulator, jitter at the destination node can be reduced. and possibly eliminated. depending on resource availability. The IDR is simple enough to be implemented wing specialized hardware. Since IDR is memory intensive, two dynamic resource allocation schemes are presented for hard and soft QoS requirements. …

Resource-Usage Prediction For Demand-Based Network-Computing, Nirav H. Kapadia, Carla E. Brodley, José A. B. Fortes, Mark S. Lundstrom

Department of Electrical and Computer Engineering Technical Reports

This document reports on an application of artificial intelligence to achieve demand-based scheduling within the context of a network-computing infrastructure. The described A1 sub-system uses tool-specific, run-time input to predict the resoura:-usage characteristics of runs. Instance-based learning with locally weighted polynornial regression is employed because of the need to simultaneoi~sly learn multiplr: polynomial concepts and the fact that knowledge is acquired increnlentally in this dornain. An innovative combination of a two-level knowledge base, and age and usage s~.atisticsa re used to: a) detect inadequate and noisy feature-vectors, 13) account for short-term variations in compute-server and network performance, and c) exploit …
