In this paper we conduct two experiments within an agent-based double auction market. These two experiments allow us to see the effect of learning and smartness on price dynamics and allocative efficiency. Our results are largely consistent with the stylized facts observed in experimental economics with human subjects. From the amelioration of price deviation and allocative efficiency, the effe...

Component adaptation needs to be taken into account when developing trustworthy systems, where the properties of component assemblies have to be reliably obtained from the properties of its constituent components. Thus, a more systematic approach to component adaptation is required when building trustworthy systems. In this paper, we illustrate how (design and architectural) patterns can be use...

A situated approach to Markovian image segmentation is proposed based on a distributed, decentralized and cooperative strategy for model estimation. According to this approach, the EM-based model estimation is performed locally to cope with spatially varying intensity distributions, as well as non-homogeneities in the appearance of objects. This distributed segmentation is performed under a col...

We analyze an interdiction scenario where an interceptor attempts to catch an intruder as the intruder moves through the area of interest. A motivating example is the detection and interdiction of drug smuggling vessels in the Eastern Pacific and Caribbean. We study two models in this paper. The first considers a non-strategic target that moves through the area without taking evasive action to ...

Lace is liable to stretch as it is passed through the feed mechanism, in which a vision system is engaged to detect the changes of the motif and find the cutting path (river) across the lace pattern. The vision system has to work with many different lace patterns, sizes and tolerate misalignment, stretch and other distortions. A Fuuy Reasoning Rule-based technique is employed in order to overco...

Starink, J.P.P. and I.T. Young, Localization of circular objects, Pattern Recognition Letters 14 ( 1993 ) 895-905. Localization of circular objects is easy when all objects are isolated, but becomes more complicated when two or more objects are touching or overlapping. In this paper we discuss a method to accurately localize the centroids and obtain estimates on the sizes. The method consists o...

The advantages of the agent-based approach are still not widely recognized outside the agent research community. We believe that there is a need for guidelines that summarize the key benefits of the agent approach to non-agent experts. Agent patterns can provide that guidance. The agent community has already started to use patterns for describing best practices of agent design. However, these p...

One of the perceived benefits of Case-Based Reasoning (CBR) is the potential to use retrieved cases to explain predictions. Surprisingly, this aspect of CBR has not been much researched. There has been some early work on knowledge-intensive approaches to CBR where the cases contain explanation patterns (e.g. SWALE). However, a more knowledge-light approach where the case similarity is the basis...

researchers made significant progress toward developing naval-based theater missile defenses during the Clinton administration, the basic NMD architecture had no naval component because that administration sought actual deployments by 2005–2006. Once in office, the Bush administration was determined to accelerate progress on missile defenses, expand research and development efforts, accept a gr...

It has been hypothesized that to maximize learning, intelligent tutoring systems should detect and respond to both cognitive student states, and affective and metacognitive states such as uncertainty. In intelligent tutoring research so far, student state detection is primarily based on information available from a single student-system exchange unit, or turn. However, the features used in the ...
