Case-Based Reasoning (CBR) is one of most successful applied AI technologies of recent years. Although many CBR systems reason locally on a previous experience base to solve new problems, in this paper we focus on distributed retrieval processes working on a network of collaborating CBR systems. In such systems, each node in a network of CBR agents collaborates, arguments and counterarguments i...

This work presents the evaluation of two mission specification and task allocation architectures. These architectures, described in part 1 of this paper, present novel means with which to integrate a case-based reasoning (CBR) mission planner with contract net protocol (CNP) based task allocation. In the first design, the CBR and runtime-CNP architecture, the case-based mission planner generate...

The United Kingdom (UK) Ministry of Defence’s (MOD) Defence Science and Technology Laboratory (Dstl) have sponsored two key development activities relating to the OneSAF Computer Generated Forces (CGF) system and development of a Common Chemical, Biological and Radiological (CBR) modelling capability. The first is an interface to enable OneSAF to operate in a High Level Architecture (HLA) 1516-...

Development and usage of Case Based Reasoning (CBR) driven medical diagnostic system requires a large volume of clinical cases that depict the problem-solving methodology of medical experts. Successful usage of CBR based systems in healthcare is constrained by the need for a continuous supply of current and correct clinical cases (in an electronic medium) from medical experts. To address this c...

Case-based reasoning (CBR) often shows significant promise for improving effectiveness of complex and unstructured decision making. Consequently, it has been applied to various problem-solving areas including manufacturing, finance and marketing. However, the design of appropriate case retrieval mechanisms to improve the performance of CBR is still a challenging issue. Most of previous studies ...

Physical activity is one of the key components for elderly in order to be actively ageing. Pulse rate is a convenient physiological parameter to identify elderly’s physical activity since it increases with activity and decreases with rest. However, analysis and classification of pulse rate is often difficult due to personal variation during activity. This paper proposed a CaseBased Reasoning (C...

Abstracf-In this paper, a new traffic source, Priority Data, is considered to access the channel with the highest priority among conventional CBR, VBR and ABR sources. In order to achieve and maintain QoS guarantee for admitted CBR and VBR sources, a QoS guaranteed wireless access protocol, the Priori@ Polling with Reservafion (PPR) protocol that consists of Priori@ Polling Scheme (PPS) and Ran...

We sought to test the hypothesis that the carotid baroreflex (CBR) alters mean leg blood flow (LBF) and leg vascular conductance (LVC) at rest and during exercise. In seven men and one woman, 25 +/- 2 (SE) yr of age, CBR control of LBF and LVC was determined at rest and during steady-state one-legged knee extension exercise at approximately 65% peak O(2) uptake. The application of 5-s pulses of...

We studied the effect of chronically denervating aortic baroreceptors (ABR; n = 6) or carotid baroreceptors (CBR; n = 7) on mean arterial pressure (MAP) and heart rate (HR) responses to hemorrhage in the dog. Neither denervation had a significant effect on basal MAP, the variability (standard deviation) of MAP, or resting HR. However, the breakpoint of MAP (defined as the volume of blood remove...
