A s we all know, the RF spectrum is a finite and exceedingly valuable resource. The practical limits of the existing spectrum, together with the exponential need for new communications, has created an increasing demand for what little free or under-utilized space remains. In general, the policy for traditional commercial services has been to place limits on… (More)
The Essentials Series was created for busy business advisory and corporate professionals. The books in this series were designed so that these busy professionals can quickly acquire knowledge and skills in core business areas. Each book provides need-to-have fundamentals for those professionals who must: • Get up to speed quickly, because they have been… (More)
Conventional intelligent or adaptive tutoring online systems rely on domain-specific models of learner behavior based on rules, deep domain knowledge, and other resource-intensive methods. We have developed and studied a domain-independent methodology of adaptive tutoring based on domain-independent signal-processing approaches that obviate the need for the… (More)
In the context of cognitive competencies, we are defined by our memories. As such, experiential data in various forms of Electronic Competency Records (ECRs), including the Learning Record Store (LRS), can be used as the basis for an Intelligent Tutoring System (ITS), scheduling medical recertification preparation and other forms of educational… (More)
The introduction of information technologies to health care organizations is believed to improve the delivery of health care process and bring a great deal of benefit to the society. However, due to the lack of understanding in the nature of such organizations, many system providers have failed to implement their technologies to their fullest potential. The… (More)
Embedded microcontroller hardware has matured to the point that organ- and system-specific modules that can be assembled in various configurations are practical. Our work developing and interconnecting organ and system modules in the cardiovascular and pulmonary systems illustrates the signaling requirements necessary to fully leverage the technology. It… (More)
We have developed a distributed, standards-based architecture that enables simulation and simulator designers to leverage adaptive learning systems. Our approach, which incorporates an electronic competency record, open source LMS, and open source microcontroller hardware, is a low-cost, pragmatic option to integrating simulators with traditional courseware.
