(2011)This paper describes a novel RSS rank based fingerprinting algorithm for indoor positioning. Because RSS rank is invariant to bias and scaling, the algorithm provides the same accuracy for any receiver device, without the ...

(2012)This paper describes rapid, simple, and costeffective treatments for producing biocompatible and longterm hydrophilic polydimethylsiloxane (PDMS) surfaces identified in an experimental study investigating 39 treatments ...

(2006)We demonstrate a simple method for monitoring alloptical poling in real time. The poling pattern created by the writing beam at the fundamental frequency and the seed beam at the secondharmonic frequency is reconstructed ...

(2011)This paper proposes a timedomain digital signal processing method for estimating and mitigating transmitter and receiver oscillator phasenoise effects in OFDM radio systems on the receiver side of the link. The idea is ...

(2013)In this paper, the operating states of a wheel loader were studied for diagnostics purposes using a real time simulation model of an articulatedframesteered wheel loader. Test drives were carried out to obtain measurement ...

(2012)Nonlinear Kalman filter and Rauch–Tung–Striebel smoother type recursive estimators for nonlinear discretetime state space models with multivariate Student’s tdistributed measurement noise are presented. The methods ...

(2013)In this paper we consider robust output regulation and the internal model principle for infinitedimensional linear systems. We concentrate on a problem where the control law is required to be robust with respect to a ...

(2009)Multithreading is an important software modularization technique. However, it can incur substantial overheads, especially in processors where the amount of architecturally visible state is large. We propose an implementation ...

(2008)Access requests to keys stored into a data structure often exhibit locality of reference in practice. Such a regularity can be modeled, e.g., by working sets. In this paper we study to what extent can the existence of ...

(2008)Hardware accelerators are used to speed up execution of specific tasks such as video coding. Often the purpose of hardware acceleration is to be able to use a cheaper or, for example, more energy economical processor for ...

(2004)We present a new technique, based on regression analysis, to determine the secondorder nonlinear optical susceptibility tensor of thin films. The technique does not require the absolute levels or phases of measured signals ...

(2005)In an array of lowsymmetry, Lshaped gold nanoparticles, slight distortions of particle shape and arm lengths eliminate the array’s mirror plane. Such asymmetries induce large angular shifts ( ∼ 10°) of the resonant ...

(2010)This paper discusses the use of high altitude platforms, HAPs, to provide mobile communication services to onground customers. The paper explains the behavior of UMTS radio network in a situation, where the service is ...

(2007)Understanding the fundamental properties of polymeric liquids remains a challenge in materials science and soft matter physics. Here, we present a simple and computationally efficient criterion for topological constraints, ...

(2008)Processor simulators are important parts of processor design toolsets in which they are used to verify and evaluate the properties of the designed processors. While simulating architectures with independent function unit ...

(20120104)In this paper the robust regulation problem for infinitedimensional systems \begin{equation*} \dot x = Ax + Bu + F_s v, \qquad y = Cx + Du + F_m v, \end{equation*} with infinitedimensional exosystems ...

(2011)A method for fitting an ellipseshaped reception region to a set of locationstamped radio signal reception reports, or location fingerprints, is presented. Reports are modelled as having a multivariate Student distribution. ...

(2012)A robust Kalman filter method for positioning using a database of wireless base station coverage areas is presented. In tests with simulated and real data, the proposed filter is found to be more accurate than static ...

(2013)In this paper we present conditions for the preservation of strong and polynomial stability of a strongly continuous semigroup under unbounded finite rank perturbations of its infinitesimal generator. In addition, we also ...
