Uncertainty management for geometric data is currently an important problem in spatial databases, image databases, and GIS. Spatial objects do not always have homogeneous interiors and sharply defined boundaries but frequently their interiors and boundaries are partially or totally indeterminate and vague. For an important kind of spatial vagueness called fuzziness this paper provides a concept...

We present preliminary work on automatic human-readable melody characterization. In order to obtain such a characterization, we (1) extract a set of statistical descriptors from the tracks in a dataset of MIDI files, (2) apply a rule induction algorithm to obtain a set of (crisp) classification rules for melody track identification, and (3) automatically transform the crisp rules into fuzzy rul...

The concept of a Petri net, a tool for the study of certain discrete dynamical systems, was invented in 1939 by Carl Adam Petri. In the attempt to characterize Boolean Petri nets, we discovered a subclass of Boolean Petri net called the crisp Boolean Petri net, viz. , the one that generates every binary vector as its marking vectors exactly once. In this paper, the construction of a crisp Boole...

Distributed proxy caches are in use throughout the world to reduce access latency and bandwidth demands for Internet object transfer. The CRISP project seeks to build more eeective distributed Web caches by exploring alternatives to the hierarchical structure and multicast handling of probes common to the most popular distributed Web cache systems. CRISP caches are structured as a collective of...

In this paper, a class of chance constrained multiobjective linear programming model with birandom coefficients is considered for vendor selection problem. Firstly we present a crisp equivalent model for a special case and give a traditional method for crisp model. Then, the technique of birandom simulation is applied to deal with general birandom objective functions and birandom constraints wh...

The juicy texture of ‘Honeycrisp’ has exploded in the Northeast apple market. Grower interest and consumer demand has made this cultivar more readily accepted than most and it continues to increase in popularity. ‘Honeycrisp’ is a bi-color apple and the flesh is cream colored with a juicy crisp texture. It has outstanding flavor characteristics and can remain crisp for several months during sto...

In this communication, we introduce an original algorithm for computing both dominant and absorbent kernels in a bipolar ordinal valued digraph. The approach relies on theoretical results recently obtained by Bisdorff, Pirlot and Roubens [8] which give a constructive – fixpoint equation based – proof of the bijection between bipolar ordinal valued kernels of such a valued digraph and the crisp ...
