Some Topics in Convolution-Based Spatial Modeling

Over the last decade, convolution-based models for spatial data have increased in popularity as a result of their flexibility in modeling spatial dependence and their ability to accommodate large datasets. The modeling flexibility is due to the framework’s moving-average construction that guarantees a valid (i.e., non-negative definite) spatial covariance function. This constructive approach to...

Some Problems in the Formal Representation of Hierarchical Knowledge

Much work has recently been devoted to the subject of ontological engineering. Although various methodologies have been developed to assist in this difficult task, these have necessarily focussed initial attempts on the overall process. Consequently, there is a need to provide advice to the ontological engineer on the details of developing ontologies. In this paper, we specifically address hier...

Effects of Representation on Solving Complex Spatial-Temporal Problems

Human data are used to study how people solve complex problems that have spatial and temporal components. Major findings include the use of task-focused representations, unexpectedly tight coupling of representation and search, time and space conflation, and use of multiple concurrent representations. The major contributions of this work include a set of abstract representations that strongly s...

Hybrid Spatial Representation Models for Strip Packing Problems

We propose two mixed-integer linear programming based approaches for the 2-D orthogonal strip packing problem. Using the knowledge of the alternative forms of time representation in scheduling formulations, we show how to efficiently combine three different concepts into the xand ydimensions. One model features a discrete representation of the x-axis (strip width) and a continuous representatio...

Some Problems in Pulmonary Disease, with Special Reference to Radiography

The extent of information which may be derived from pulmonary radiography, also the limitations of this method, are worthy of consideration. Assuming that the technique for the production of satisfactory radiographs leaves nothing to be desired, difficulties of correct interpretation are responsible for a certain sense of disappointment, and tend to diminish the usefulness of pulmonary radiogra...
