Title: Generalizing indexical-functional reference

Abstract

The goals of situated agents generally do not specify particular objects: they require only that some suitable object should be chosen and manipulated (e.g. any red block). Situated agents engaged in deictic reference grounding, however, may well track a chosen referent object with such fixity of purpose that an unchosen object may be regarded as an obstacle even though it satisfies the agent`s goals. In earlier work this problem was bridged by hand-coding. This paper lifts the problem to the symbol level, endowing agents with perceptual referent selection actions and performing those actions as required to allow or disallow opportunistic re-selection of referents. Our work preserves the ability of situated agents to find and track specific objects, adds an ability to automatically exploit the opportunities allowed by nonspecific references, and provides a starting point for studying how much opportunistic perception is appropriate.

  • Toxicity reference values (TRVs) are used in ecological risk assessment (ERA) to quantify the effect of a contaminant on ecological receptors. Extrapolation of toxicity data derived from surrogate species to receptors of concern at the site introduces uncertainty and conservatism into the risk assessment. Functional grouping was used at the INEL to group species based on similar taxonomic orders and tropic levels. Extrapolation of toxicity data to functional groups may introduce additional uncertainty and conservatism. Understanding of the uncertainty and conservatism inherent in a risk assessment is important when making risk management decisions and communicating the results to the public.more » This study examined the conservatism and uncertainty inherent in more traditional approaches to development of TRVs on selected species and functional groups. Several contaminants were selected based on availability of toxicity data. Contaminants with several high quality toxicity studies with chronic results on multiple species were selected. The known value was compared to the extrapolated values from each approach. This process was repeated for several species and contaminants as possible with the available data. This paper discusses and compares the uncertainty and conservatism of extrapolations from one species to the receptor of concern (or functional group).« less
  • Passive design potentials of the case study house, which was originally an 1860 Iowa farm house, were analyzed in respect to historical image, aesthetic qualities, structural characteristics, functional room layout, and site potentials and constraints. The south portion of the old house was rearranged to work in conjunction with a sun space addition to become open living space on the first floor and a sewing and craft area on a second floor balcony. Mass for heat storage was accomplished through the use of a one lane exercise pool, heat sink housed within the sun space. Performance data indicate that themore » thermal mass has proved to be more than adequate in storing heat and in minimizing diurnal temperature swings within the living space.« less
  • Recent research in airborne oil spill remote sensing [FBFG94] leads towards modular systems that consist of several distinct sensors to combine the capabilities of the different sensor classes. The Medusa project [GHW96] is an example of a distributed system. It exhibits a distributed architecture to provide a maximum of flexibility, concurrency and safety and must clearly be rated as a classical distributed application from a computer science point of view. This article describes the {open_quotes}sensor description system{close_quotes} (SDS). SDS allows the developer of sensing systems to minimize the effort of integrating his particular subsystem into an existing application. By applyingmore » formal methods to the integration process a developer is able to describe the abstract properties of his sensing system like parameter values, generated data format, applicable methods on the data etc. and can thus rely on the SDS tools to produce the required software backends automatically: A graphical user interface for parameter control, an online visualization, data transfer facilities to a database and finally the evaluation and interpretation facility. Ibis technique puts future sensing enterprises in a position where different classes of sensors can easily be combined almost off-the-shelf to build powerful systems in very short turnaround times. 10 refs., 7 figs.« less
  • We present a new construction approach for symmetric lifted B-spline wavelets on irregular polygonal control meshes defining two-manifold topologies. Polygonal control meshes are recursively refined by stationary subdivision rules and converge to piecewise polynomial limit surfaces. At every subdivision level, our wavelet transforms provide an efficient way to add geometric details that are expanded from wavelet coefficients. Both wavelet decomposition and reconstruction operations are based on local lifting steps and have linear-time complexity.
