This paper proposes a fast and accurate calibration method to calibrate multiple multimodal sensors using a novel photogrammetry system for fast localization of EEG sensors. The EEG sensors are placed on human head and multimodal sensors are installed around the head to simultaneously obtain all EEG sensor positions. A multiple views' calibration process is implemented to obtain the transformat...

STUDY OBJECTIVE To validate the APACHE (acute physiology and chronic health evaluation) III unadjusted and similar hospital mortality estimate models on 30-day mortality, and to propose a simple approach to modeling local 30-day in-hospital mortality of critically ill hospitalized adults for quality management and risk-adjusted monitoring. DESIGN Noninterventional, observational study. PATI...

LiDAR and cameras have been broadly utilized in computer vision and autonomous vehicle applications. However, in order to convert data between the local coordinate systems, we must estimate the rigid body transformation between the sensors. In this paper, we propose a robust extrinsic calibration algorithm that can be implemented easily and has small calibration error. The extrinsic calibration...

The Delaunay tessellation and topological regression is a local simplex method for multivariate calibration. The method, developed within computational geometry, has potential for applications in online analytical chemistry and process monitoring. This study proposes a novel approach to perform prediction and extrapolation using Delaunay calibration method. The main property of the proposed ext...

In this paper we propose an extension of the Libor market model with a high-dimensional specially structured system of square root volatility processes, and give a road map for its calibration. As such the model is well suited for Monte Carlo simulation of derivative interest rate instruments. As a key issue, we require that the local covariance structure of the market model is preserved in the...

Reliable international normalized ratio (INR) determination depends on accurate values for international sensitivity index (ISI) and mean normal prothrombin time (MNPT). Local ISI calibration can be performed to obtain reliable INR. Alternatively, the laboratory may determine INR directly from a line relating local log(prothrombin time [PT]) to log(INR). This can be done by means of lyophilized...

This paper addresses two aspects of triangulation-based range sensors using structured laser light: calibration and measurements consistency. We present a direct calibration technique which does not require modelling any speciic sensor component or phenomena , therefore is not limited in accuracy by the inability to model error sources. We also introduce some consistency tests based on two-came...

1 There exists an extensive academic literature on software cost estimation that explores techniques such as boot strapping, assorted analogy methods such as nearest neighbor, and even highly non-linear ‘models’ such as decision trees. However, industry “best practice” virtually ignores the academic literature and continues to rely upon standard regression-based algorithms and most often local ...
