Background
We have designed a patient‐based real‐time quality control (PBRTQC) procedure to detect analytical shifts and review analytical trends of measurement procedures.
Methods
All the nine months' patient results of total thyroxine (TT4), total triiodothyronine (TT3), free thyroxine (FT4), free triiodothyronine (FT3), and thyrotropin (TSH) measured by three identical analyzers were divided...
This paper aims at reliability assessment of power semiconductor in hybrid DC switch. Design considerations of reliability issues are explained. Specific focus is given to a temperature-based condition monitoring technique via thermo-sensitive electrical parameters. VCE, td(off), and dVCE/dt of IGBT are presented as the indicator of junction temperature and calibrated. Comparative experiments with...
This paper describes a closed-form algorithm of recovering the projected centers of a parallel circle-pair from one image. By using the common tangents of a circle-pair as the key helper for solving the problem, we have developed an algorithm that only uses real, visible and concrete geometrical features for describing itself and for representing the intermediate results. This makes the jobs of checking...
This paper describes a method that detects two co-planar circular shaped objects having the same radius from an image with clutter background. We propose an unique RANSAC based method for detecting the candidates of ellipses that divides the circular region centered at the assumed ellipse center into N equal sectors, then fits the edge points selected randomly from each sector. We propose three geometrical...
A fuzzy decoupling technique is proposed for model validation of large-scale power systems. To solve the problem of incredibility lying in power system dynamic simulations, a wide area pattern (WAP) is defined which reflects the parameter effects of certain component to the space-time trajectories, especially with consideration of the characteristics of huge amount of measurements and model parameters...
The spatial fixed-pattern noise (FPN) compromises severely the quality of the acquired imagery, even makes such images inappropriate for some applications. In order to lower the FPN, some critical nonuniformity correction (NUC) algorithms such as NUC based on linear model, scene-based NUC and so on have been developed. But each algorithm has some drawbacks: restricted application in small dynamic...
This paper presents a novel camera calibration method for a system consists of a sensor-less mobile robot and an external camera. This method can estimate the focal length and the viewing direction of the camera relative to a plane where the sensor-less mobile robot moves from a single image of an arbitrary circle on that plane. Since it is easy to let a four-wheel mobile car to move along a circular...
