* This work is supported by EU-IST-2001-34401 VAMPIRE. Abstract – Within a hybrid vision / inertial tracking system proper calibration of the sensors and their relative pose is essential. We present a new method for 3-axis inertial sensor calibration based on model fitting and a method to find the rotation between vision and inertial system based on rotation differences. We achieve a coordinate...

Many computer models contain unknown parameters which need to be estimated using physical observations. Tuo and Wu (2014) shows that the calibration method based on Gaussian process models proposed by Kennedy and O’Hagan (2001) may lead to unreasonable estimate for imperfect computer models. In this work, we extend their study to calibration problems with stochastic physical data. We propose a ...

Modern robotic spectral solar instruments designed for retrievals of aerosol optical depth (AOD), such as the Multi-Filter Rotating Shadowband Radiometer (MFRSR) (Harrison et al. 1994), usually operate in an unattended mode. Thus their raw data sets sample a wide range of atmospheric conditions, most of which are undesirable for aerosol optical depth analysis. In addition, these instruments are...

Due to the limitation of water renewable resources on one hand and increasing growth in consuming different parts such as agriculture, industry, urban, environment other hand, face management these valuable many challenges. Present study attempts clarify recent condition problem introduce effective tools supply sector. In order achieve this purpose, simulating model HEC-Res Sim was used for Dok...

INTRODUCTION Continuous glucose monitoring system is a valuable instrument to measure glycemic control, which uses a retrospective calibration based upon 3 to 4 capillary glucose meter values inserted by the patient each day. OBJECTIVE We evaluated the interference of calibration during the dawn period in the system accuracy. METHODS The monitoring data were retrospectively divided into two...

This article compares the results of two surveys in Salvador, Bahia State, Brazil, on prevalence and severity of dental fluorosis in 12 and 15-year-olds. The article discusses the survey methodologies in relation to their sampling process, calibration of examiners, and data collection procedures, comparing the resulting differences using chi-square and 95% confidence intervals obtained with the...
