Metric Operators, Generalized Hermiticity and Lattices of Hilbert Spaces
2015
Pseudo-Hermitian quantum mechanics (QM) is a recent, unconventional, approach to QM, based on the use of non-self-adjoint Hamiltonians, whose self-adjointness can be restored by changing the ambient Hilbert space, via a so-called metric operator. The PT-symmetric Hamiltonians are usually pseudo-Hermitian operators, a term introduced a long time ago by Dieudonné for characterizing those bounded operators A that satisfy a relation of the form GA = A G, where G is a metric operator, that is, a strictly positive self-adjoint operator. This chapter explores further the structure of unbounded metric operators, in particular, their incidence on similarity. It examines the notion of similarity betw…
WQ*-algebras of measurable operators
2012
Every C*-algebra \(\mathfrak{A}\) has a faithful *-representation π in a Hilbert space \(\mathcal{H}\). Consequently it is natural to pose the following question: under which conditions, the completion of a C*-algebra in a weaker than the given one topology, can be realized as a quasi *-algebra of operators? The present paper presents the possibility of extending the well known Gelfand — Naimark representation of C*-algebras to certain Banach C*-modules.

Automated detection and localization system of myocardial infarction in single-beat ECG using Dual-Q TQWT and wavelet packet tensor decomposition.
2019
Abstract Background and objective It is challenging to conduct real-time identification of myocardial infarction (MI) due to artifact corruption and high dimensionality of multi-lead electrocardiogram (ECG). In the present study, we proposed an automated single-beat MI detection and localization system using dual-Q tunable Q-factor wavelet transformation (Dual-Q TQWT) denoising algorithm. Methods After denoising and segmentation of ECG, a fourth-order wavelet tensor (leads × subbands × samples × beats) was constructed based on the discrete wavelet packet transform (DWPT), to represent the features considering the information of inter-beat, intra-beat, inter-frequency, and inter-lead. To red…
Real-Time Implementation of Signal Processing Techniques for Disturbances Detection
2019
The real-time analysis of power quality (PQ) disturbances and islanding detection for distributed generation (DG) system using signal processing algorithms are still at a premature stage. Quick and reliable detection of islanding and PQ disturbances needs renewed focus. This paper is concentrated on the implementation of advanced signal processing techniques in field-programmable gate array (FPGA) to identify PQ and islanding events in real time. The proposed scheme is based on orthogonal empirical mode decomposition (OEMD) implemented in FPGA. This technique does not suffer from the loss of signal characteristics with successive decomposition levels. The performance of said technique is de…
La confrontació per l'opinió pública: Els editorials dels diaris sobre la diada de catalunya de 2012
2014
Els articles editorials que publiquen els diaris continuen sent postulats ideològics de referència a l'hora d'identificar els mitjans i els seus lectors amb alguns dels actors que apareixen en qualsevol conflicte, com és el cas dels conflictes polítics. Aquest treba ll és un estudi qualitati u i quantitatiu que busca analitzar els editorials amb l'objectiu de caracteritzar els actors amb els quals la capçalera queda alineada i com persuadeixen els se us lectors i legitimen arguments al voltant del cas de la manifestació de la Diada de Cata lunya de 2012. El corpus de l'estudi se centra en 97 editorials de 10 diaris que responen a contextos territorials diferents: El País i El Mundo -context…

Dostojevska reliģiski filosofisko ideju recepcija latviešu filozofu un teologu darbos
2016
Bakalaura darbā “Dostojevska reliģiski filozofisko ideju recepcija latviešu filozofu un teologu darbos” tiek salīdzināti un analizēti Zentas Mauriņas un Alberta Freija pētījumi par izcilā krievu rakstnieka un psiholoģiskās prozas meistara Fjodora Dostojevska daiļradē sastopamajām reliģiski filozofiskajām idejām. Viņu pētījumu uzmanības centrā ir tādi F.Dostojevskim tuvi jēdzieni kā Dievs, nemirstība un cilvēks, kā arī paša F.Dostojevska pasaules redzējums. Pirmajā nodaļā tiek aplūkotas latviešu rakstnieces Z. Mauriņas domas par krievu lielmeistara reliģiskajām un filozofiskām idejām, kā arī kritika par F.Dostojevskim veltīto monogrāfiju. Otrajā nodaļā tiek skatīta un analizēta latviešu teol…
