Adaptive forecasting of exchange rates with panel data [PDF]

open access: greenInternational Journal of Forecasting, 2010
This article investigates the statistical and economic implications of adaptive forecasting of exchange rates with panel data and alternative predictors. The candidate exchange rate predictors are drawn from (i) macroeconomic 'fundamentals', (ii) return/volatility of asset markets and (iii) cyclical and confidence indices.

Optimization Schemes for UAV Data Collection with LoRa 2.4 GHz Technology in Remote Areas without Infrastructure

open access: yesDrones, 2022
Recently, the use of unmanned aerial vehicles (UAVs) and LPWANs (low-power wide-area networks) has been a good solution to the problem of data collection for environmental monitoring in remote areas without infrastructure, and there are many valuable ...

Adaptive Estimation of Hazard Rate with Censored Data [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2008
In this article, we study hazard projection estimators under right-censoring of the observations. We consider projection spaces generated by trigonometric or piecewise polynomials. First, we derive bounds on the MISE of the estimators. These bounds imply that the estimator reaches the standard optimal rate associated with the regularity of the hazard ...

Adaptive MIMO-VLC System for High Data Rate Communications [PDF]

open access: yes2020 IEEE Globecom Workshops (GC Wkshps, 2020
In this paper, we describe a high-speed indoor MIMO-VLC system that adapts the number of MIMO channels and data rate according to channel conditions at user locations. A transmitter coordination algorithm and a data rate adaptive modulation technique have been investigated. At each user location across the room, the number of MIMO transmission channels

Observer‐based controllers with data dropout rate adaptation [PDF]

open access: yesInternational Journal of Robust and Nonlinear Control, 2017
SummaryIn this work, we address the observer‐based control problem for networked control systems with an unknown time‐varying packet arrival rate (PAR) and under root mean square‐norm bounded disturbances. We assume packetized transmissions of both measurement and control input through a communication network with successful delivery acknowledgement ...

HADR: A Hybrid Adaptive Data Rate in LoRaWAN for Internet of Things

open access: yesICT Express, 2022
Resource allocation (e.g., spreading factor and transmit power) to static and mobile Internet of Things (IoT) applications is significantly challenging. To meet the IoT application requirements, LoRaWAN assigns resources to static and mobile end devices (
