One of the essential factors influencing the prediction accuracy of multivariate calibration models is the quality of the calibration data. A local regression strategy, together with a wavelength selection approach, is proposed to build the multivariate calibration models based on partial least squares regression. The local algorithm is applied to create a calibration set of spectra similar to ...

A class of three-legged modular reconfigurable parallel robots is designed and constructed for precision assembly and light machining tasks by using standard active and passive joint modules in conjunction with custom designed links and mobile platforms. Since kinematic errors, especially the assembly errors, are likely to be introduced, kinematic calibration becomes particularly important to e...

Digital color copiers have the potential to generate high-quality color output when properly maintained and calibrated. Maintenance is typically provided by the local sales organization that is authorized to repair and service your specific copier brand and model. Calibration means tuning or tweaking the color output of the copier for consistent results. This technicall document describes the c...

In this paper we propose a Libor model with a high-dimensional specially structured system of driving CIR volatility processes. A stable calibration procedure which takes into account a given local correlation structure is presented. The calibration algorithm is FFT based, so fast and easy to implement.

The calibration of electromagnetic clusters is one of the key issues of ATLAS (and the LHC) in 2007. The cluster algorithm starting from electronically calibrated calorimeter cells will be described. Local position and local energy variations are corrected for. As a last step, longitudinal weights are applied to correct for energy loss upstream of the calorimeter. Strongly influenced by testbea...

Structure from Motion can be improved by using multicamera systems without overlapping views to provide a large combined field of view. The extrinsic calibration of such camera systems can be computed from local reconstructions using hand-eye calibration techniques. Nevertheless these approaches demand that motion constraints resulting from the rigid coupling of the cameras are satisfied which ...

Light eld rendering allows fast visualization of complex scenes by view interpolation from images of densely spaced camera viewpoints. The light eld data structure requires calibrated viewpoints, and rendering quality can be improved substantially when local scene depth is known for each viewpoint. In this contribution we propose to combine light eld rendering with a geometry-based structure-fr...

We introduce a local volatility model for the valuation of options on commodity futures by using European vanilla option prices. The corresponding calibration problem is addressed within an online framework, allowing the use of multiple price surfaces. Since uncertainty in the observation of the underlying future prices translates to uncertainty in data locations, we propose a model-based adjus...

BACKGROUND The need to perform local International Sensitivity Index (ISI) calibrations and in particular the requirement for a manual method for prothrombin time (PT) determination, have proved to be obstacles to application of the WHO scheme for PT standardization. METHODS We used international normalized ratio (INR) derived with a set of only 5 European Concerted Action on Anticoagulation ...
