Autism is thought to be associated with abnormal hemispheric specialization and left-hemispheric dysfunction. Brain functional imaging using 133Xe-SPECT (single photon emission computed tomography) was used to measure left/right asymmetry and absolute values of regional cerebral blood flow (rCBF) in 18 children with autism aged from four to 17 years and 10… (More)
Developmental dysphasia, a severe childhood learning disorder, is thought to result from problems in hemispheric specialization involving both left and right cerebral hemispheres. Regional cerebral blood flow (rCBF) was measured at rest and during stimulation of both hemispheres independently: dichotic listening for the left, dichaptic palpation for the… (More)
An important issue in many multiagent systems is the way in which agents can be coordinated in order to perform different roles. This paper proposes a method by which the agents can self-organize based on the changes of their individual utilities. We assume that the tasks given to the agents have a number of attributes and complexity levels, and that the… (More)
—Data Mining is the process of extraction of interesting (non-trivial, implicit, previously unknown and potentially useful) information or patterns from data in large databases. Agents are defined as software or hardware entities that perform some set of tasks on behalf of users with some degree of autonomy. In order to work for somebody as an assistant, an… (More)
Acknowledgments I thank Professor John Bartholdi for his guidance and financial support. Without him the accomplishment of this thesis would have been impossible. Special thanks must go to Professor Donald Eisenstein, who always inspires me on my work, for co-advising me.
This paper aims at designing some data mining methods of evaluating the seismic vulnerability of regions in the built infrastructure. A supervised clustering methodology is employed, based on k-nearest neighbor graphs. Unlike other classification algorithms, the method has the advantage of taking into account any distribution of training instances and also… (More)
