In spite of great advances in the automatic drawing of medium and large graphs, the tools available for drawing small graphs exquisitely (that is, with the aesthetics commonly found in professional publications and presentations) are still very primitive. Commercial tools, e.g., Claris Draw, provide minimal support for aesthetic graph layout. At the other extreme, research prototypes based on constraint methods are overly general for graph drawing. Our system improves on general constraint-based approaches to drawing and layout by supporting on...

The compact and harmonious layout of ads and text is a fundamental and costly step in the production of commercial telephone directories ( ?Yellow Pages?). We formulate a canonical version of Yellow-Pages pagination and layout (YPPL) as an optimization problem in which the task is to position ads and text-stream segments on sequential pages so as to minimize total page length and maximize certain layout aesthetics, subject to constraints derived from page-format requirements and positional relations between ads and text. We present a heuristic-...

We present a simple system for interactively specifying lighting parameters, including position, for high-quality image synthesis. Unlike inverse approaches to the lighting-design problem, we do not require the user to indicate a priori the desired illuminative characteristics of an image. In our approach the computer proposes, culls, and organizes a set of candidate lights automatically, using an elementary measure of image similarity as the basis for both culling and organization. The user then browses the set of candidate-light images, selec...

Full-body, unencumbered, gestural interfaces offer new possibilities for computer painting tools. However, traditional painting metaphors and current gestural input technology are not well suited to one another; the user cannot be tracked with sufficient accuracy to support brush-like or penlike painting. Our approach to this problem has been to interpose different layers of abstraction between input gestures and painting actions. We illustrate this approach with two sample applications implemented in the context of the MIT Media Lab?s Interact...

We consider Magnetoencephalographic (MEG) data in a signal detection framework. Our data set consists of responses evoked by the voiced syllables /b? / and /d? / and the corresponding voiceless syllables /p?/ and /t?/. The data yield well to principal component analysis (PCA), with a reasonable subspace in the order of three components out of 37 channels. To discriminate between responses to the voiced and voiceless versions of a consonant we form a feature vector by either matched ?ltering or wavelet packet decomposition and use a mixture-of-e...

We present the continuous-time particle filter (CTPF) ? an extension of the discrete-time particle filter for monitoring continuous-time dynamic systems. Our methods apply to hybrid systems containing both discrete and continuous variables. The dynamics of the discrete state system are governed by a Markov jump process. Observations of the discrete process are intermittent and irregular. Whenever the discrete process is observed, CTPF samples a trajectory of the underlying Markov jump process. This trajectory is then used to estimate the contin...

Abstract A 1-b digital cross correlator for use in radio astronomy was designed and built at Harvard. Although only 16 channels (lags) were built in hardware, a recycling scheme allows the incoming data to be processed through the correlator several times over to multiply the number of hardware channels by a factor that can be quite large at low sample rates. For example, for a spectral window of 400 kHz, 112 lags can be computed and for 125 kHz, 400 lags. To do this the correlator is connected to a minicomputer (Supernova) for both input and ...
