there exist a number of factors that affect the quality laser scanner. in other words, the accuracy of a terrestrial scanner is limited extensively by systematic errors and thus must be calibrated. indeed, calibration is a prerequisite for obtaining 3d precise and reliable data from point clouds. until now, several models have been proposed to improve the accuracy of laser scanner data, most of...

In this contribution, a design of a synthetic calibration genetic circuit to characterize the relative strength of different sensing promoters is proposed and its specifications and performance are analyzed via an effective mathematical model. Our calibrator device possesses certain novel and useful features like modularity (and thus the possibility of being used in many different biological co...

A Markov model is constructed for studying the counterparty risk in a CDS contract. The ‘wrong-way risk’ in this model is accounted for by the possibility of the common default of the reference name and of the counterparty. A dynamic copula property as well as affine model specifications make pricing and calibration very efficient. We also consider the issue of dynamically hedging the CVA with ...

This paper investigates the question of the sophistication level, in the mean of behavior and intelligence, one should endow artificial traders in order to obtain, with realistic market microstructure, not only both qualitative and quantitative stylized facts in an artificial market. For this purpose, we introduce an agent-based simulation environment with an architecture close to the Euronext-...

Quantitative structure-activity relationship (QSAR) analysis has been carried out with a series of 107 anti-HIV HEPT compounds with antiviral activity, which was performed by chemometrics methods. Bi-dimensional images were used to calculate some pixels and multivariate image analysis was applied to QSAR modelling of the anti-HIV potential of HEPT analogues by means of multivariate calibration,...

Published in: proceedings SPIE 4401 (2001) 'Recent Developments in Traceable Dimensional Measurements', Decker, Brown (ed) ABSTRACT For the calibration of length standards and instruments, various methods are available for which usually an uncertainty according to the GUM [1] can be set up. However, from calibration data of a measuring instrument it is not always evident what the uncertainty wi...
