We present results of experiments testing the Fast Gauss Transform, Improved Fast Gauss Transform, and Dual-Tree methods (using kd-tree and Anchors Hierarchy data structures) for fast Kernel Density Estimation (KDE). We examine the performance of these methods with respect to data set size, dimension, allowable error, and data set structure (“clumpiness”), measured in terms of CPU time and memo...

The automated design scheme called exploratory modelling for controller optimization (EMCO) is re-examined to obtain simple robust controllers for complex plant dynamics. The allowable gain error (AGE) function is revised to quantify a frequency dependent bound of model gain errors which allow for both robust servo performance and the required stability robustness margin to be maintained. AGE l...

The ABL4 analyser is designed for stat determination of blood gas (pCO2, pO2), pH, potassium and haemoglobin (Hb), a panel particularly adapted to the follow-up of liver transplantation. The performance of the analyser in classical tests was evaluated; in addition, K+ measurements were performed in specific conditions (linearity in a non-physiological range, erythrocyte interference). The evalu...

Six sigma concepts provide a quality management system (QMS) with many useful tools for managing quality in medical laboratories. This Six Sigma QMS is driven by the quality required for the intended use of a test. The most useful form for this quality requirement is the allowable total error. Calculation of a sigma-metric provides the best predictor of risk for an analytical examination proces...

This paper proposes a novel monocular SLAM approach. For a triplet of successive keyframes, the approach inteleaves the registration of the three 3D maps associated to each image pair in the triplet and the refinement of the corresponding poses, by progressively limiting the allowable reprojection error according to a simulated annealing scheme. This approach computes only local overlapping map...

The Selective Catalytic Reduce (SCR) is studied. The unknown parameters of the SCR kinetic model equations are fitted based on the Genetic Algorithm (GA), which is in the range of the allowable error, compared to the experimental data. Then in AVL Boost software, the simulation results of SCR reaction are obtained. Compared to the test data, the simulation results prove that the parameter ident...

With the advancement of communications technology comes with the demand for higher data rate services such as multimedia, voice, and data over both wired and wireless links. New modulation schemes are required which must be able to adapt to different requirements of individual services in terms of their data rate, allowable Bit Error Rate (BER), and maximum delay. To improve the BER performance...

The problem of proficiency evaluation of clinical chemistry laboratories is considered in terms of the accuracy, precision, and allowable limits of error of 10 common analytical procedures, and in terms of the proficiency of individual analysts and the occurrence of gross laboratory mistakes. The concept of the operational chart is developed, and its use is illustrated. Operational charts summa...

Abstract In this article, the bond performance between recycled concrete and corroded steel bars is analyzed by nonlinear numerical simulation. The result shows that maximum strength bar decreases with increase in corrosion rate; when large, simulated good agreement experimental strength; small, relatively poor strength, but there still an error within allowable range; slip increases rate excee...

A modulation system is proposed that continuously adjusts its data rate in response to signal strength variations in a fading channel. The optimum variation of data rate with channel conditions is determined, and includes the effects of feedback channel time delay, the interval between rate changes, and restriction of the number of allowable rates. Application of these results to a full duplex ...
