Un enfoque bayesiano para la ubicación de la fuente de emisión acústica modal
Ecomatemático, 2019 Modal Acoustic Emission (MAE) is a branch of Acoustic Emission (AE) with proven capabilities for Structural Health Monitoring (SHM) of plate-like structures. MAE differences from AE in that MAE uses the understanding of the wave propagation to

Mixing and combining with AOA and TOA for the enhanced accuracy of mobile location [PDF]
[[abstract]]Position location has become a hot issue over the past few years in wireless communication. Providing the accurate location information of the mobile station (MS) is necessitated by the Emergent 911 call in United States. The angle of arrival

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Maximum likelihood time-of-arrival estimation using antenna arrays: Application to global navigation satellite systems [PDF]
, 1998 The problem of estimating the time-of-arrival (TOA) of a known signal in the presence of interferences and multipath propagation is addressed. This problem, is essential in high precision receivers of the Global Navigation Satellite Systems.

Multiple Parameter Estimation With Quantized Channel Output
, 2010 We present a general problem formulation for optimal parameter estimation based on quantized observations, with application to antenna array communication and processing (channel estimation, time-of-arrival (TOA) and direction-of-arrival (DOA) estimation)

Bayesian CRLB for hybrid ToA and DoA based wireless localization with anchor uncertainty [PDF]
, 2015 In this paper, we derive the Bayesian Cramér-Rao lower bound for three dimensional hybrid localization using time-of-arrival (ToA) and direction-of-arrival (DoA) types of measurements.

Ultra Wideband Channel Characterization and Ranging in Data Centers [PDF]
, 2007 This paper presents a detailed measurement based characterization of the Ultra Wideband (UWB) channels in a data center environment and examines the accuracy of direct ranging using Time of Arrival (ToA) measurements. Modern data centers present a unique

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.
