Dynamics of a harmonic oscillator coupled with a Glauber amplifier
2020
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system may be exactly subdivided into invariant finite dimensional subspaces. Resorting to the Jordan-Schwinger map, the dynamical problem within each invariant subspace may be traced back to an effective SU(2) Hamiltonian model expressed in terms of spin variables only. This circumstance allows to analytically solve the dynamical problem and thus to study the exact dynamics of the oscillator-amplifier system under specific time-dependent scenarios. Peculiar physical effects are brought to light by comparing the dynamics…
On the ‘expanded local mode’ approach applied to the methane molecule: isotopic substitutions CH3D ←CH4 and CHD3 ←CH4
2014
Operator perturbation theory and the symmetry properties of the axially symmetric XYZ3 (C3v) type molecules are used for the determination of the spectroscopic parameters in the form of functions of structural parameters and parameters of the intramolecular potential function. Several relations between sets of spectroscopic parameters of these molecules are obtained. The ‘expanded local mode’ model and the general isotopic substitution theory are used to estimate the relations between spectroscopic parameters of CH3D and CHD3, on one hand, and with the Td symmetric isotopic species, CH4, on the other hand. Test calculations with the isotopic relations show that even without including prior …
On-Demand Security Framework for 5GB Vehicular Networks
2023
Building accurate Machine Learning (ML) at-tack detection models for 5G and Beyond (5GB) vehicular networks requires collaboration between Vehicle-to-Everything (V2X) nodes. However, while operating collaboratively, ensuring the ML model’s security and data privacy is challenging. To this end, this article proposes a secure and privacy-preservation on-demand framework for building attack-detection ML models for 5GB vehicular networks. The proposed framework emerged from combining 5GB technologies, namely, Federated Learning (FL), blockchain, and smart contracts to ensure fair and trustedinteractions between FL servers (edge nodes) with FL workers (vehicles). Moreover, it also provides an ef…
The Commented Walk Method as a Way of Highlighting Precise Daily Mobility Difficulties – A Case Study Focusing on Cognitive or Mental Diseases
2016
Abstract The French Act of 11 February 2005 on equal rights and opportunities, participation and citizenship of people with disabilities highlights the need “for people with disabilities or reduced mobility” to have access to the complete mobility chain of the transport system. This law was initially planned to apply from 2015. Many efforts have been made to improve life for those with physical, visual and, to a lesser extent, hearing impairments. But there is a lot of room for improvement in situations regarding psychological, cognitive and mental impairment. This is largely due to a lack of knowledge on the difficulties experienced by the above when they travel. The national quantitative …
Od konfliktu do komunii. W kontekście luterańsko-katolickich obchodów 500-lecia Reformacji
2017
17 czerwca 2013 r. w Genewie i w Watykanie ogłoszono wspólny dokument teologów rzymskokatolickich i luterańskich pt.: Od konfliktu do komunii. Luterańsko-katolickie wspólne upamiętnienie Reformacji w 2017 r. Jego celem było głębsze, bezpośrednie przygotowanie luteranów i katolików do wspólnego upamiętnienia 500. rocznicy Reformacji. Przesłanie deklaracji stało się inspiracją dla przygotowania niniejszego opracowania. Nie chodzi w nim o szczegółowe omawianie dokumentu, ale przede wszystkim o sformułowanie, w oparciu o jego przesłanie, istotnych paradygmatów określających cel, okoliczności, zadania i perspektywy związane ze wspólnym obchodzeniem przez luteranów i katolików 500-lecia Reformacj…
