Robust and fast similarity search for moving object trajectories
- In Proc. ACM SIGMOD Int. Conf. on Management of Data
, 2005
"... An important consideration in similarity-based retrieval of moving object trajectories is the definition of a distance function. The ex-isting distance functions are usually sensitive to noise, shifts and scaling of data that commonly occur due to sensor failures, errors in detection techniques, dis ..."

, disturbance signals, and different sampling rates. Cleaning data to eliminate these is not always possible. In this paper, we introduce a novel distance function, Edit Distance on Real sequence (EDR) which is robust against these data imper-fections. Analysis and comparison of EDR with other popular dis
A Cross-Country Comparison of Labor Market Frictions
, 2000
"... In this paper we dene and estimate measures of labor market imper-fection in the context of an equilibrium search and matching framework. The method uses readily available data on distributions of unemployment and job durations and wages. We estimate an index of search frictions, the magnitude of st ..."

DESIGN STUDY OF A NEW BEAM SEPARATOR FOR PEEM3∗
"... Aberration correction of photoemission electron micro-scopes (PEEM) requires use of a magnetic beam separator. This device is a complex integrated magnetic system and is essentially fixed in its optical properties hence very suscep-tible to problems caused by mechanical or magnetic imper-fections. H ..."

Coherence properties of cycling chaos
"... Cycling chaos is a heteroclinic connection between several chaotic attractors, at which switching between the chaotic sets occur at growing time intervals. Here we characterize the coherence properties of these switchings, considering nearly periodic regimes that appear close to the cycling chaos du ..."

due to imper-fections or to instability. Using numerical simulations of coupled Lorenz, Roessler, and logistic map models, we show that the coherence is high in the case of imperfection (so that asymptotically the cycling chaos is very regular), while it is low close to instability of the cycling
Project Co-ordination:
, 2008

Applications of quantum chaos to realistic quantum computations and sound treatment on quantum computers
"... We discuss the quantum algorithms simulating complex dynamics on quantum computers in presence of imper-fections. The e®ects of random errors and static imperfections for quantum gates are analyzed. We also study numerically how a sound signal stored in a quantum computer can be recognized and resto ..."

LHC APERTURE MEASUREMENTS
"... The mechanical aperture of the Large Hadron Collider (LHC) is a critical parameter for the operation of the ma-chine due to the high stored beam intensities in the super-conducting environment. Betatron and momentum aper-tures must be therefore precisely measured and optimised. In this paper, we pre ..."

The experimental results are compared with the expectations from the as-built model of the LHC aperture, taking into account the optics imper-fections of the superconducting magnets. The impact of these measurements on various aspects
Distributed Diagnosis of Permanent and Intermittent Faults in Wireless Sensor Networks
"... Abstract. Faults are inevitable in Wireless Sensors Networks (WSNs) because of physical defects caused due to environmental hazards, imper-fection or hardware and/or software related glitches. If faults are not detected and handled properly the consequences may be inexorable in case of safety critic ..."

New measurements of technical efficiency, allocative efficiency, and price efficiency are proposed. They have three desirable properties. First, they measure efficiency loss in mone ..."
