Our approach is a departure from the procedures usually employed in the following important respects: (1) We recognize the typ ica l ly overlooked d is t inc t ion between lines and edges; f inding l ines offers s igni f icant simpl i f icat ions not available when searching for edges. (2) The perceptual pr imit ive we extract from the image to Indicate the local presence of l inear structure i...

We present a. theory of a modeler’s problem decomposition skills in the context of opthal Teasowing the use of qualitative modeling to strategically guide numerical explorations of objective space. Our technique, called activity annlysl:s, applies to the pervasive family of linear and non-linear, constrained optimization problems, and easily integrates with any existing numerical approach. Acti...

In the current post-genomics world, a relevant question on the minds of many phycologists might be: do we really need more algal genomes or, should we stop and focus on the hard job of developing genetic tools and other resources for already sequenced taxa? This question has, in our opinion, a clear answer: we need to do both. Here, we focus on the genome sequencing side and discuss the followi...

What he is asked for by the question, is a description—a set of predicates, visual properties in this case, of a person he has observed. Both answers fulfill this task—they give a description which, though only a summary, is satisfactory for anybody who knows what Sidney Greenstreet looks like. More than this, the first utterance also repeats what the task is about—to describe the robber— altho...

In this paper, we design a continuous, t ime-varying tracking controller for an underactuated surface vessel in the presence of uncertainty associated with the hydrodynamic damping coefficients. A Lyapunov-based approach is used to ensure that the posi t ion/orientat ion tracking error is ultimately confined to a ball that can be made arbitrarily small. The result is achieved via the judicious ...
