An Interchange Standard and System for Browsing Digital Documents
(1995-05)
With the advent of fast global digital communication networks, information will increasingly be delivered in electronic form. In addition, as libraries become increasingly more computerized, not just card catalogs but ...
Connecting Homes to the Internet: An Engineering Cost Model of Cable vs. ISDN
(1995-06)
Using the World Wide Web at 28.8 Kbps (or less) can be a frustrating experience: a multimedia page that takes a fraction of a second to download at Ethernet speeds takes many seconds at modem rates. Two enhancements to ...
Increasing Cross-Domain Call Batching Using Promises and Batched Control Structures
(1995-06)
In a client-server system, it may be possible for the client to corrupt server data through unsafe access methods or programming error. A common method for protecting the server data is to separate the client and server ...
Piecemeal Graph Exploration by a Mobile Robot*
(1995-01)
We study how a mobile robot can piecemeal learn an unknown environment. The robot's goal is to learn a complete map of its environment, while satisfying the constraint that it must return every so often to its starting ...
Enhanced Reality Visualization in a Surgical Environment
(1995-01-01)
Enhanced reality visualization is the process of enhancing an image by adding to it information which is not present in the original image. A wide variety of information can be added to an image ranging from hidden ...
Virtual Model Control of a Biped Walking Robot
(1995-12-01)
The transformation from high level task specification to low level motion control is a fundamental issue in sensorimotor control in animals and robots. This thesis develops a control scheme called virtual model control ...
On Convergence Properties of the EM Algorithm for Gaussian Mixtures
(1995-04-21)
"Expectation-Maximization'' (EM) algorithm and gradient-based approaches for maximum likelihood learning of finite Gaussian mixtures. We show that the EM step in parameter space is obtained from the gradient via a ...
A Dynamical Systems Model for Language Change
(1995-12-01)
Formalizing linguists' intuitions of language change as a dynamical system, we quantify the time course of language change including sudden vs. gradual changes in languages. We apply the computer model to the historical ...
