This paper implements a field programmable gate array(FPGA-) based face detector using a neural network (NN) and the bitwidth reduced floating-point arithmetic unit (FPU). The analytical error model, using the maximum relative representation error (MRRE) and the average relative representation error (ARRE), is developed to obtain the maximum and average output errors for the bit-width reduced F...

This paper examines efficient methods for the calculation of open circuit voltage distortion in salient pole synchronous generators with damper windings. It then proceeds to examine the role of damper bars in the level of distortion. The simplified finite element method employed is inclusive of eddy current effects, dynamic field current and full interaction of all MMF sources. It allows accura...

We evaluated the analytical performance of 10 representative channels on the new microprocessor-controlled DuPont aca Ill according to the guidelines (draft documents PSEP-2, 3, and 4) proposed by the Instrument Evaluation Subcommittee of the National Committee for Clinical Laboratory Standards. These guidelines were used for the experimental design and data analysis for the precision and accur...

BACKGROUND Reference procedures are required for evaluating the accuracy of routine analytical systems for uric acid (UA). External quality assessment (EQA) for UA has only been conducted with quality controls in China, and the results have not been published. This study was designed to investigate both the trueness and inter-laboratory precision of UA measurements among routine analytical syst...

Survey error is known to be pervasive and bias even simple, but important, estimates of means, rates, totals, such as the poverty unemployment rate. In order summarize analyze extent, sources, consequences survey error, we define empirical counterparts key components Total Error Framework that can estimated using data combination. Specifically, estimate total decompose it into three high level ...

Errors made during the sample preparative process contribute significantly to the total analytical error of immunoassays. Reduction in the magnitude of these errors have been made by improvements in the manualfluid handling systems and mechanization of the individual steps in the process. The mechanization has been stimulated by developments in both computing hardware and software. A laboratory...

Expansion of human activities causes dispersion of pollutants in the subsurface environment. The fate and movement of dissolved substances in soils and groundwater has generated considerable interest out of concern for the quality of the subsurface environment. Many analytical solutions for partial differential equations exist in soil science. Numerical solutions are more general, and often mor...
