Wireless Sensor Networks for Condition Based Maintenance: Security and Reliability
2009
Masteroppgave i informasjons- og kommunikasjonsteknologi 2009 – Universitetet i Agder, Grimstad In this thesis we present the requirements needed for a Condition Based Main- tenance (CBM) solution by using Wireless Sensor Networks(WSN). The sensor network needs to be secure and reliable to be implemented in a CBM solution, hence we have chosen the popular ZigBee protocol to see how it fulfill the reliability requirements of transmission delay, lost packets and battery consumption. The security requirements is based on the CIA(confidentiality, integrity, availability) triad for security objectives, and in this thesis we will give a general overview of the security mechanisms used in ZigBee t…

Entanglement interferometry for precision measurement of atomic scattering properties.
2003
We report on a two-particle matter wave interferometer realized with pairs of trapped 87Rb atoms. Each pair of atoms is confined at a single site of an optical lattice potential. The interferometer is realized by first creating a coherent spin-mixture of the two atoms and then tuning the inter-state scattering length via a Feshbach resonance. The selective change of the inter-state scattering length leads to an entanglement dynamics of the two-particle state that can be detected in a Ramsey interference experiment. This entanglement dynamics is employed for a precision measurement of atomic interaction parameters. Furthermore, the interferometer allows to separate lattice sites with one or …
Generation of Pair Coherent States in Two-dimensional Trapped Ion
2001
We consider a two-dimensional (2D) trapped ion model in which two laser beams drive the corresponding vibrational motions and are carrier resonant with the two-level of the ion. Due to the coherent superposition of two sub-Rabi oscillations involved in the bimodal vibrations, the Rabi frequency degeneration and offset may occur in this model. This provides the possibility of generating the pair coherent state in the 2D trapped ion.
Three-mode two-boson Jaynes–Cummings model in trapped ions
2006
In this paper, we analyse a two-boson three-mode Jaynes–Cummings model which can be implemented in the context of trapped ions. The symmetries of the Hamiltonian are brought to light and analysed in detail in order to solve the eigenvalue problem. The calculation of the time evolution operator shows the possibility of realizing interesting applications, such as the generation of nonclassical states.
Nature of the non-exponential primary relaxation in structural glass-formers probed by dynamically selective experiments
1998
Several experimental methods feature the potential to distinguish between slow and fast contributions to the non-exponential, ensemble averaged primary response in glass-forming materials. Some of these techniques are based on the selection of subensembles using multi-dimensional nuclear magnetic resonance, optical bleaching, and non-resonant spectral hole burning. Others, such as the time-dependent solvation spectroscopy, measure microscopic responses induced by local perturbations. Using several of these methods it could be demonstrated for various glass-forming materials that the non-exponential relaxation results from a superposition of dynamically distinguishable entities. The experime…
Exact Mechanical Hierarchy of Non-Linear Fractional-Order Hereditariness
2020
Non-local time evolution of material stress/strain is often referred to as material hereditariness. In this paper, the widely used non-linear approach to single integral time non-local mechanics named quasi-linear approach is proposed in the context of fractional differential calculus. The non-linear model of the springpot is defined in terms of a single integral with separable kernel endowed with a non-linear transform of the state variable that allows for the use of Boltzmann superposition. The model represents a self-similar hierarchy that allows for a time-invariance as the result of the application of the conservation laws at any resolution scale. It is shown that the non-linear spring…
La Carta sociale europea come parametro interposto nella recente giurisprudenza costituzionale: novità e questioni aperte
2019
In two judgments delivered in 2018 (No. 120 and No. 194), the Constitutional Court for the first time referred to provisions of the European Social Charter as an interposed norm in the constitutional review of primary laws. The two judgments, however, leave two questions open. First, in judgment No. 120, the Court recognizes taht the European Social Charter may complement Article 117, paragraph 1, of the Constitution, as it constitutes a natural integration of the European Conventionof Human Rights on the social level, which in fact distinguishes it from "ordinary" international agreements. In its subsequent judgment No. 194, on the other hand, the Court speaks of treaties with constitution…
How domain-sensitive are existential constructions? Evidence from Swedish and Dutch weather reports
2020
International audience; [Introduction] Over the last two decades, linguists have shown considerable interest in the advantages of CxG-theories for various linguistic sub-disciplines. A particular question that has arisen within more “applied” frameworks, is whether or not constructions can have domain-specific manifestations regarding meaning and/or form (Fischer/Nikiforidou 2015; Bücker/Günther/Imo 2015; Gautier/Bach 2019). However, sufficient empirical analyses are currently missing, and this research question needs to be more systematically tested for constructions in various languages and different LSP-oriented domains. Beside the mere “applied” focus, such work can lead to interestin…
Affordances of telecollaboration tools for English for Specific Purposes online learning
2016
This paper explores students' perceptions of the affordances of different telecollaboration tools used in an innovation project for English for Specific Purposes online learning carried out between the University of Valencia (Spain) and Wofford College (South Carolina, United States) during the school year 2015-2016. Different tools for synchronous and asynchronous communication were used. The asynchronous tools included a discussion forum, a wiki, social networking websites and Google forms; while the tools used for synchronous communication were text, voice and video chat, videoconferencing tools and Google Drive. All the tools were accessible through the online platform used in the proje…
