Indoor localization accuracy estimation from fingerprint data
(Institute of Electrical and Electronics Engineers Inc., 2017)The demand for indoor localization services has led to the development of techniques that create a Fingerprint Map (FM) of sensor signals (e.g., magnetic, WiFi, bluetooth) at designated positions in an indoor space and ...

Leastcost firing sequence estimation in labeled Petri nets with unobservable transitions
(2007)This paper develops a recursive algorithm for estimating the leastcost transition firing sequences that match the observation of a sequence of labels produced by transition activity in a given labeled Petri net. The Petri ...

Minimum initial marking estimation in labeled petri nets
(2013)This technical note develops algorithms for estimating the minimum initial marking(s) following the observation of a sequence of labels produced by underlying transition activity in a known labeled Petri net (PN). Since ...

Article
A model for estimating pollution emissions for individual economic activities
(1998)To be effective, environmental policies must be informed by reliable assessments of the impact of economic activities. In turn, such impact assessments require comprehensive information on the pollution profiles of particular ...

Article
Modeling wireless fading channels via stochastic differential equations: Identification and estimation based on noisy measurements
(2008)This paper is concerned with modeling and identification of wireless channels using noisy measurements. The models employed are governed by Stochastic Differential Equations (SDEs) in state space form, while the identification ...

Article
A new estimation scheme for the effective number of users in internet congestion control
(2011)Many congestion control protocols have been recently proposed in order to alleviate the problems encountered by TCP in highspeed networks and wireless links. Protocols utilizing an architecture that is in the same spirit ...

Article
NonParametric Sequential Estimation of a Regression Function Based on Dependent Observations
(2013)This article presents a sequential estimation procedure for an unknown regression function. Observed regressors and noises of the model are supposed to be dependent and form sequences of dependent numbers. Two types of ...

Article
Nonlinear estimation for a class of systems
(2009)This paper considers nonlinear estimation problems for classes of models, and employs relative entropy to describe the uncertainty classes. Two optimization problems are formulated on general Banach spaces, and their ...

Article
On the posterior median estimators of possibly sparse sequences
(2005)We adopt the Bayesian paradigm and discuss certain properties of posterior median estimators of possibly sparse sequences. The prior distribution considered is a mixture of an atom of probability at zero and a symmetric ...

Article
Optimal filtering over uncertain wireless communication channels
(2011)In this letter, filtering over wireless communication channels subject to packet losses is considered. The packet losses are assumed to follow a Bernoulli distribution. The latter is interpreted as a special case of a ...

Article
Position error signal estimation at high sampling rates using data and servo sector measurements
(2003)The sampling rate in most hard disk drives (HDDs) is limited by the number of servo burst sectors that have prewritten position error signal (PES) data and by the spinning speed of the HDD. This paper presents an algorithm ...
