High-frequency current transformers are popular noninvasive inductive wideband sensors. Despite the simplicity in design and operational principle, implementation of such sensors for partial discharge (PD) applications requires careful consideration, particularly higher frequency range where traveling wave attenuation distortion relevant. First, role variables, including core materials, winding...

1 Abstract A method is presented to extract space curves, deened by diierential invariants, at increasing scales. The curves are considered as the intersection of two iso-surfaces in 3D, so their moving paths or orbits can be explicitly obtained in scale space as the intersection of two iso-surfaces in 4D. This method is based on a novel algorithm to search for iso-surfaces and their intersecti...

The polyphase filter approach to quadrature demodulation is presented. It is shown to be well suited for the implementation of purpose-designed high performance, wide bandwidth quadrature demodulators in low-cost Field-Programmable Gate Array (FPGA) technology. The duplicated polyphase filter approach is introduced, as a way to increase the maximum allowable input signal bandwidth while maintai...

The implementation of a robotic workstation in the clinical laboratory involves considerations and compromises common to any instrument design and development activity. The trade-off between speed and flexibility not only affects the way the instrument interacts with human operators and other devices (the 'real-world interface'), but also places limitations on the adaptation of chemistries to t...

This chapter provides an overview of the evidence-based treatment (EBT) paradigm, beginning with definitional issues, followed by a discussion on use of the iterative process and the importance of strong academic-practice partnerships to inform the development, selection, and implementation of EBTs.The discussion then turns to the importance of attaining, measuring, and sustaining fidelity to t...

I N T R O D U C T I O N The SAFE project [Balzer 77] at ISI is constructing a computer model which exhibits certain aspects of process understanding. SAFE accepts a written, pseudo-English process descript ion and produces a formal specification of the described process. The resulting specification is encoded in a language wi th formal syntax and semantics. The process is specified in operation...
