The recent integration of sensor-based interactive systems into buildings presents a significant aesthetic opportunity for architectural design. Beyond static, permanent structures, architecture can utilize sensor technologies to develop dynamic responses to human needs, expanding the creative palette of the architect to incorporate computer-mediated information exchange between inhabitants and...

One of the great challenges in photonics has been to modify silicon to enhance light emission properties. In this review article we survey recent studies which have generated light from silicon in a variety of ways including introduction of emissive centers, anodization, fabrication of quantum-confined structures and by utilizing non-linear effects. Each method offers insight into silicon as an...

Crystal growth has been widely studied for many years, and, since the pioneering work of Burton, Cabrera and Frank, spirals and target patterns on the crystal surface have been understood as forms of tangential crystal growth mediated by defects and by two-dimensional nucleation. Similar spirals and target patterns are ubiquitous in physical systems describable as excitable media. Here, we demo...

My research is in “physics-based” vision (Wolff et al. 1992; Healey and Jain 1994). Physicsbased vision takes seriously radiometric, as well as geometric, constraints in image analysis. The approach has led to new computational methods to determine scene parameters from images including photometric stereo (Woodham 1980; Woodham 1981) and multiple light source optical flow (Woodham 1990). The id...

One of the current challenges in Biology is to understand how living systems self-organize to achieve emergent properties that improve fitness. In order to act coherently as a unit, each organism must display system-level dynamics that span it. As organisms evolve and become more sophisticated, they must be able to develop increasingly complex organism-wide behaviors that result from the local ...

Environmental psychology categorizes “physical environment” as “typically neutral,” only coming into selfconscious awareness when individuals form stable and enduring representations of it [1]. We see this manifest in the real world when the steeple of a church is able to communicate that it is a place for reflection and religious gathering; the bricks and ivy of Harvard Yard signifies years of...

In this paper we describe the translation facilities as a component of EDM-2 database. We introduce a new approach to translation that is different from the traditional translators in databases and the standard neutral file approach. First, we define design views, which are different from database views in that they allow manipulation of data, and they represent the same object or information i...
