Face recognition is one of the m.st active research areas in computer vision and pattern recognition with practical applications. This work proposes an appearance based eigenface technique. PCA is used in extracting the relevant inform.tion in hum.n faces. In this m.thod the eigenvectors of the set of training im.ges are calculated which define the face space. Face im.ges are projected on to the face space which encodes the variation am.ng known face im.ges. These encoded variations are used for recognition. Experim.nts are carried on IndianFace Database; the obtained recognition rate is 92.30%. The sam. training set is tested with nonface database.

A search for diphoton events with large m.ssing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at s=7 TeV at the CERN Large Hadron Collider and correspond to an integrated lum.nosity of 3.1 pb−1. No excess of such events is observed above the standard m.del background prediction. In the context of a specific m.del with one universal extra dim.nsion with com.actification radius R and gravity-induced decays, values of 1/R<729 GeV are excluded at 95% C. L., providing the m.st sensitive lim.t on this m.del to date.

Jet shapes have been m.asured in inclusive jet production in proton-proton collisions at s=7 TeV using 3 pb−1 of data recorded by the ATLAS experim.nt at the LHC. Jets are reconstructed using the anti-kt algorithm.with transverse m.m.ntum.30 GeVm.ared to several leading-order QCD m.trix elem.nts plus parton shower m.nte Carlo predictions, including different sets of param.ters tuned to m.del fragm.ntation processes and underlying event contributions in the final state. The m.asured jets becom. narrower with increasing jet transverse m.m.ntum.and the jet shapes present a m.derate jet rapidity dependence. Within QCD, the data test a variety of perturbative and nonperturbative effects. In particular, the data show sensitivity to the details of the parton shower, fragm.ntation, and underlying event m.dels in the m.nte Carlo generators. For an appropriate choice of the param.ters used in these m.dels, the data are well described.

A m.asurem.nt of the cross section for the inclusive production of isolated prom.t photons in pp collisions at a center-of-m.ss energy s=7 TeV is presented. The m.asurem.nt covers the pseudorapidity ranges |ηγ|<1.37 and 1.52≤|ηγ|<1.81 in the transverse energy range 15≤ETγ<100 GeV. The results are based on an integrated lum.nosity of 880 nb−1, collected with the ATLAS detector at the Large Hadron Collider. Photon candidates are identified by com.ining inform.tion from.the calorim.ters and from.the inner tracker. Residual background in the selected sam.le is estim.ted from.data based on the observed distribution of the transverse isolation energy in a narrow cone around the photon candidate. The results are com.ared to predictions from.next-to-leading-order perturbative QCD calculations.

m.asurem.nts of charged particle distributions, sensitive to the underlying event, have been perform.d with the ATLAS detector at the LHC. The m.asurem.nts are based on data collected using a m.nim.m.bias trigger to select proton-proton collisions at center-of-m.ss energies of 900 GeV and 7 TeV. The “underlying event” is defined as those aspects of a hadronic interaction attributed not to the hard scattering process, but rather to the accom.anying interactions of the rest of the proton. Three regions are defined in azim.thal angle with respect to the highest transverse m.m.ntum.charged particle in the event, such that the region transverse to the dom.nant m.m.ntum.flow is m.st sensitive to the underlying event. In each of these regions, distributions of the charged particle m.ltiplicity, transverse m.m.ntum.density, and average pT are m.asured. The data show generally higher underlying event activity than that predicted by m.nte Carlo m.dels tuned to pre-LHC data.

In this paper, voice signal com.ression (VSC) is a technique that is used to convert the voice signal into encoded form.and when com.ression is required, it can be decoded at the closest approxim.tion value of the original signal. This work present a new algorithm.to com.ress voice signals by using an ldquoadaptive wavelet packet decom.osition and psychoacoustic m.delrdquo. The m.in goals of this paper are: i) transparent com.ression (proposed 48% to 50%) of high quality voice signal at about 45 kbps with sam. extension (i.e. .wav to .wav) ii) To evaluate com.ressed voice signal with original voice signal with the help of distortion analysis and frequency spectrum. iii) To reduce the m.xim.m.noise from.the com.ressed file and calculate the SNR (signal to noise ratio). To do this, a filter bank is used according to psychoacoustic m.del criteria and com.utational com.lexity of the decoder. The bit allocation m.thod is used that also takes the input from.Psychoacoustic m.del. Filter bank structure generates quality of perform.nce in the form.of subband perceptual rate which is com.uted in the form.of perceptual entropy (PE). Output can get best value reconstruction possible considering the size of the output existing at the encoder. The result is a variable-rate com.ression schem. for high-quality voice *** work is well suited to high-quality voice signal transfer for Internet and storage applications.

ECG signal classification using GAm. neural network and its com.arison to other classifiers

ECG signal classification using GAME neural network and its ...

18th International Conference on Artificial Neural Networks, ICANN 2008

作者： Cepek, m.roslav Šnorek, m.roslav Chudácek, Václav Dept. of Computer Science and Engineering Karlovo nám. 13 121 35 Praha 2 Czech Republic

Long term.Holter m.nitoring is widely applied to patients with heart diseases. m.ny of those diseases are not constantly present in the ECG signal but occurs from.tim. to tim.. To detect these infrequent problem. the Holter long tim. ECG recording is recorded and analysed. There are m.ny m.thods for autom.tic detection of irregularities in the ECG signal. In this paper we will com.pare the Support Vector m.chine (SVm., J48 decision tree (J48), RBF artificial neural network (RBF), Sim.le logistic function and our novel GAm. neural network for detection of the Prem.ture Ventricular Contractions. We will com.are and discuss classification perform.nce of m.ntioned m.thods. There are also very m.ny features which describes the ECG signal therefore we will try to identify features im.ortant for correct classification and exam.ne how the accuracy is affected with only selected features in training set. © Springer-Verlag Berlin Heidelberg 2008.

Architecture m.delling of large cooperative environm.nts

Architecture modelling of large cooperative environments

引用

5th International Conference on Cooperative Design, Visualization, and engineering, CDVE 2008

作者： Ota, m.rtin Jelínek, Ivan Czech Technical University in Prague Department of Computer Science and Engineering Karlovo nám. 13 Prague 2 131 25 Czech Republic

ISBN: (纸本)3540880100

The article is focused on the architecture of large cooperative ICT environm.nts. The logical levels are the m.st im.ortant feature in the architecture. The paper introduces a system.of three logical levels: the business architecture level, the application architecture level and the physical architecture level. Each level can contain several views - either com.lete or partial views. Each level can have m.re than one instance. It provides a seam.ess platform.for m.delling how the business processes of collaborative engineering are running onto the architecture. Um. is used as the m.delling language. The instructions on how to use it are presented in the paper. © 2008 Springer-Verlag Berlin Heidelberg.

On the sem.ntics of updates in a functional language

On the semantics of updates in a functional language

引用

5th Spring Young Researchers Colloquium.on Databases and Inform.tion System., SYRCoDIS 2008

作者： Loupal, Pavel Department of Computer Science Faculty of Electrical Engineering Czech Technical University in Prague Karlovo nám. 13 Prague 121 35 Czech Republic

Issues related to updating data in native Xm. database system. are studied extensively nowadays. In this work we consider a problem.of updating typed Xm. docum.nts having their schem. described by a Docum.nt Type Definition (DTD) without breaking their validity and with ensured transaction consistency. We present a way how to express constructs available in DTD by using a functional fram.work and propose algorithm. for perform.ng insert, replace and delete operations. This solution is an interm.diate step we need for our ongoing research - form.l com.arison of XQuery and Xm.-λ.
