The British Columbia Center for Disease Control laboratory performs approximately 95% of all hepatitis C virus (HCV) antibody tests for the province's 4 million inhabitants. In 2002, the laboratory tested 96,000 specimens for anti-HCV antibodies, of which 4,800 (5%) were seroreactive and required confirmation of active infection. Although HCV RNA assays with a sensitivity of 50 IU/ml or less ar...

Controlling a complex dynamic system such as a plane or a crane usually requires a skilled operator Such a control skill is typically hard to reconstruct through introspection There fore an attractive approach to the reconstruction of control skill involves machine learning from operators control traces also known as behavioural cloning In the most common approach to behavioural cloning a contr...

To the Editor: Human chorionic gonadotropin (CG) is a heterodimeric glycoprotein hormone composed of noncovalently associated and subunits that are synthesized by trophoblastic tissue in pregnancy. Systemic modification and degradation of the intact CG molecule and subunits leads to molecular heterogeneity in the serum and urine (1 ). The subunit is a component of nicked CG (CGn), CG -subunit (...

This paper presents a methodology for synthesizing, under uncertainty, a sequence of robust, discrete control actions to drive a continuous dynamical plant through admissible trajectories specified via temporal logic expressions . An action is defined as a modification to the value of a controllable exogenous variable . The TEQSIM algorithm combines qualitative simulation with temporal logic mo...

We present a qualitative approach to the dynamical control of bipedal walking that allows us to combine the benefits of passive dynamic walkers with the ability to walk on uneven terrain. We demonstrate an online control strategy, synthesizing a stable walking gait along a sequence of irregularly spaced stepping stones. The passive dynamic walking paradigm has begun to establish itself as a use...

This paper presents the qualitative heterogeneous control framework, a methodology for the design of a controlled hybrid system based on attractors and transitions between them. This framework designs a robust controller that can accommodate bounded amounts of parametric and structural uncertainty. This framework provides a number of advantages over other similar techniques. The local models us...

Controlling a complex dynamic system, such as a plane or a crane, usually requires a skilled operator . Such a control skill is typically hard to reconstruct through introspection . Therefore an attractive approach to the reconstruction of control skill involves machine learning from operators' control traces, also known as behavioural cloning . In the most common approach to behavioural clonin...

The test aids in the diagnosis of recent or active rubella infection and in the determination of immune status. These materials are intended to be ...

-Robust control has long been the purview of quantitative linear control techniques, while qualitative, symbolic control has been deemed more suitable to obtaining complex control objectives that require only low output precision. The intelligent techniques of Fuzzy control have, however, shown promise in obtaining results comparable to those obtained from H∞ and H2 robust control techniques. O...
