Integrity is a critical requirement for aerospace navigation systems. In this paper integrity issues are coped with a new FDI technique implemented by a snapshot RAIM algorithm based on position domain tests. The approach consists of the joint exploitation of all the possible Least Squares (LS) solutions of the GPS linear estimation problem under a single fault on a pseudorange measurement. The...

Abstract Computer holography is a growing research field that must pay attention to two main issues concerning computing effort: the visualization of 3D virtual scene with photo-realistic quality and bottleneck related hologram digitizalition limits. This work shows computational approach based on Monte Carlo path-tracing algorithm, which accounts for both geometrical physical phenomena involve...

The DENIS and 2MASS near infrared surveys are presented. Their applications in extragalactic astronomy and cosmology are listed. The prospects for a rapid spectroscopic followup survey of a near infrared selected sample of nearly 10 galaxies are illustrated with MonteCarlo simulations.

This note reports about the way it is possible to reweight four-fermion (4-f) events in order to account for the O(α) radiative corrections implemented in double pole approximation (DPA). The recommended choice for the DELPHI users is described and commented. This work is based on the new codes implementing DPA developed in the frame of the 2000 LEP2 Montecarlo workshop.

Determine a non-myopic solution to the sequential decision making problem of monitoring and optimising a space and time dependent function using a moving sensor. Contributions: Sequential Bayesian Optimisation (SBO) Formulate SBO as a Partially Observed Markov Decision Process (POMDP). Find non-mypic solution for the POMDP analog of SBO using MonteCarlo Tree Search (MCTS) and Upper Confidence B...

Power estimation is an important issue in digital VLSI circuit design. The estimation of average power dissipation of a circuit through exhaustive simulation is impractical due to the large number of primary inputs and their combinations. In this paper, two algorithms based on least square estimation are proposed for determining the average power dissipation in CMOS circuits. Least square estim...

In this work, a new analysis approach is used to analyze the performance of orthogonal frequency division multiplexing-noncoherent amplitude shift keying systems for frequency hopping multiple access networks with additive white Gaussian noise. A simple, yet accurate, expression was derived to describe the system bit error rate (BER). Montecarlo simulations were used to verify the accuracy of t...
