ACCES: Offline accuracy estimation for fingerprintbased localization
(Institute of Electrical and Electronics Engineers Inc., 2017)In this demonstration we present ACCES, a novel framework that enables quality assessment of arbitrary fingerprint maps and offline accuracy estimation for the task of fingerprintbased indoor localization. Our framework ...

Action functional stochastic H∞ estimation for nonlinear discrete time systems
(2002)This paper presents an action functional, sample path optimization technique, for formulating and solving nonlinear discretetime stochastic H∞ estimation problems. These H∞ problems are formulated as minimax dynamic games ...

Article
Adaptive mixing control with multiple estimators
(2012)A recently proposed adaptive control scheme with mixing involves the use of precalculated candidate controllers whose output is weighted on the basis of the parameter estimates generated by an online parameter estimator. ...

Article
Aggregation of spectral density estimators
(2014)Given stationary time series data, we study the problem of finding the best linear combination of a set of lag window spectral density estimators with respect to the mean squared risk. We present an aggregation procedure ...

An AMFM model for motion estimation in atherosclerotic plaque videos
(2007)We present new multidimensional AmplitudeModulation FrequencyModulation (AMFM) methods for motion estimation. For a single AMFM component we show that the optical flow constraint leads to separate equations for amplitude ...

An analytical framework for estimating TCO and exploring data center design space
(2013)In this paper, we present EETCO: an estimation and exploration tool that provides qualitative assessment of data center design decisions on TotalCostofOwnership (TCO) and environmental impact. It can capture the ...

Atherosclerotic plaque motion analysis from ultrasound videos
(2006)In this paper, we describe a collection of algorithms that are used to provide motion trajectory estimates from atherosclerotic plaque ultrasound videos. Our approach is based on the use of four different optical flow ...

Article
Bounds on the number of markings consistent with label observations in petri nets
(2009)In this paper, we consider state estimation in discreteevent systems (DESs) modeled by labeled Petri nets and present upper bounds on the number of system states (or markings) that are consistent with an observed sequence ...

Article
Complexvalued tapers
(2005)The spectral estimation method based on the average of short, tapered periodograms is reexamined. The bias of such estimators is typically O(1/b2), where b is the length of the short blocks. Much of the current researeh ...

Convergence of belief propagation algorithms on binary pairwise Gibbs random fields
(2011)In this paper, we study the convergence of belief propagation algorithms (BPAs) on binary pairwise Gibbs random fields (BPGRFs). Exploiting the equivalence of BPA on the graph associated with BPGRF and the corresponding ...

Demo: Indoor geolocation on multisensor smartphones
(2013)In this demo, we present an efficient hybrid indoor positioning solution that uses multisensory locationoriented observations, including WiFi, accelerometer, gyroscope and digital compass data, that are widely available ...

Article
Discretetime risksensitive filters with onGaussian initial conditions and their ergodic properties
(2001)We study asymptotic stability properties of risksensitive filters with respect to their initial conditions. We consider a linear timeinvariant systems with initial conditions that are not necessarily Gaussian. We show ...

Conference Object
Distributed network size estimation and average degree estimation and control in networks isomorphic to directed graphs
(2012)Many properties of interest in graph structures are based on the nodes' average degree (i.e., the average number of edges incident to/from each node). In this work, we present asynchronous distributed algorithms, based on ...

Article
Dynamic misspecification in nonparametric cointegrating regression
(2012)Linear cointegration is known to have the important property of invariance under temporal translation. The same property is shown not to apply for nonlinear cointegration. The limit properties of the NadarayaWatson (NW) ...

Estimation and identification of timevarying longterm fading channels via the particle filter and the em algorithm
(2011)In this paper, we are concerned with the estimation and identification of timevarying wireless longterm fading channels. The dynamics of the fading channels are captured using a meanreverting linear stochastic differential ...

Article
Estimation and inference in functional mixedeffects models
(2007)Functional mixedeffects models are very useful in analyzing functional data. A general functional mixedeffects model that inherits the flexibility of linear mixedeffects models in handling complex designs and correlation ...

Article
Estimation of rotational frequency responses
(2003)Rotational frequency response functions are potentially valuable for structural damage detection but are difficult to obtain because of the practical problems of applying a pure moment. In the literature various indirect ...

Feedback control over packet dropping network links
(2007)This paper studies stabilization schemes for a discretetime control systems in which the feedback loop includes a network link that may suffer packet drops. We model the packet dropping network link as an erasure channel ...

Identification and high bandwidth control of hard disk drive servo systems based on sampled data measurements
(2007)One of the key factors that determines the track density of a hard disk drive (HDD) is the performance characteristics of the HDD servo system, the control system that positions the READ/WRITE magnetic head close to the ...
