description: Η παρούσα διατριβή επιχειρεί να συμβάλει στη μελέτη του πολύπλευρου συγγραφικού έργου του Ιωάννη Ζωναρά, ιστορικού, νομικού και θεολόγου της εποχής των Κομνηνών, μέσα από την εξέταση των τεσσάρων αγιολογικών κειμένων που μας έχουν παραδοθεί με το όνομά του. Στα επιμέρους κεφάλαια εξετάζονται τα προβλήματα γνησιότητας των κειμένων αυτών, η χειρόγραφη παράδοσή τους, οι πηγές και τα πρότυπά τους, οι σχέσεις τους με άλλα έργα του συγγραφέα και κυρίως με την "Επιτομή ιστοριών", τα γλωσσικά και υφολογικά χαρακτηριστικά τους καθώς και η θέση τους στο ευρύτερο πλαίσιο της αγιολογικής παραγωγής του 12ου αιώνα. Περιορισμένα σε αριθμό και σε έκταση, τα αγιολογικά έργα του Ιωάννη Ζωναρά βοηθούν αφενός ελάχιστα στο να αποκαταστήσουμε μια πληρέστερη εικόνα για τη ζωή του συγγραφέα, επιτρέπουν όμως από την άλλη πλευρά, να αντιληφθούμε το έργο του Ζωναρά ως ένα ενιαίο σύνολο, ενώ ταυτόχρονα η μελέτη τους αναδεικνύει διαφορετικές πτυχές της αγιολογικής γραμματείας της εποχής των Κομνηνών, οι οποίες δεν είχαν επισημανθεί από την μέχρι τώρα έρευνα.
description: The aim of the present thesis is to contribute to the study of the versatile literary work of John Zonaraw, the famous historian, jurist and theologian of the Comnenian era, through the examination of the four hagiographical texts that have come down to us with his name. In the various chapters are being treated subjects such as the authenticity of the texts, their manuscript tradition, their models and sources, their relationship to other works of the same author and especially to the "Epitome Historiarum", their language and style as well as their place in the context of the hagiographical production of the twelfth century. Small in number and size, the hagiographical works of John Zonaras offer on the one hand very little to our knowledge of the details of the author's life, but they help us on the other hand to understand Zonaras' work as an entity, while their study reveals different aspects of the Comnenian hagiography that had not been pointed outby the research so far.
Properties of an algebraic spin liquid on the kagome lattice

description: In recent work, we argued that a particular algebraic spin liquid (ASL) may be the ground state of the S = 1/2 kagome lattice Heisenberg antiferromagnet. This state, which lacks a spin gap, is appealing in light of recent experiments on herbertsmithite (ZnCu3(OH)6Cl2). Here, we study the properties of this ASL in more detail, using both the low-energy effective field theory and Gutzwiller-projected wavefunctions. We identify the competing orders of the ASL -- among them we find a set of magnetic orders lying at the M-points of the Brillouin zone, the q = 0 magnetic ordered state, the "Hastings" valence-bond solid (VBS) state, and a pattern of vector spin chirality ordering corresponding to one of the Dzyaloshinskii-Moriya (DM) interaction terms present in herbertsmithite. We discuss the detection of the magnetic and VBS competing orders in experiments. While we focus on a clean system without DM interaction, we consider the effects of small DM interaction and argue that, surprisingly, it leads to spontaneously broken time reversal symmetry (for DM interaction that preserves XY spin rotation symmetry, there is also XY magnetic order). Our analysis of the projected wavefunction provides an estimate of the "Fermi velocity" that characterizes all low-energy excitations of the ASL -- this allows us to estimate the specific heat, which compares favorably with experiments. We also study the spin and bond correlations of the projected wavefunction and compare these results with those of the effective field theory. While the spin correlations in the effective field theory and wavefunction seem to match rather well (although not completely), the bond correlations are more puzzling. We conclude with a discussion of experiments in herbertsmithite and make several predictions.

description: One of the fundamental characteristics of a nonlinear system is how it transfers correlations in its inputs to correlations in its outputs. This is particularly important in the nervous system, where correlations between spiking neurons are prominent. Using linear response and asymptotic methods for pairs of unconnected integrate-and-fire (IF) neurons receiving white noise inputs, we show that this correlation transfer depends on the output spike firing rate in a strong, stereotyped manner, and is, surprisingly, almost independent of the interspike variance. For cells receiving heterogeneous inputs, we further show that correlation increases with the geometric mean spiking rate in the same stereotyped manner, greatly extending the generality of this relationship. We present an immediate consequence of this relationship for population coding via tuning curves.
Multimodal Meaning Representation for Generic Dialogue Systems Architectures

description: An unified language for the communicative acts between agents is essential for the design of multi-agents architectures. Whatever the type of interaction (linguistic, multimodal, including particular aspects such as force feedback), whatever the type of application (command dialogue, request dialogue, database querying), the concepts are common and we need a generic meta-model. In order to tend towards task-independent systems, we need to clarify the modules parameterization procedures. In this paper, we focus on the characteristics of a meta-model designed to represent meaning in linguistic and multimodal applications. This meta-model is called MMIL for MultiModal Interface Language, and has first been specified in the framework of the IST MIAMM European project. What we want to test here is how relevant is MMIL for a completely different context (a different task, a different interaction type, a different linguistic domain). We detail the exploitation of MMIL in the framework of the IST OZONE European project, and we draw the conclusions on the role of MMIL in the parameterization of task-independent dialogue managers.
Dynamic properties of sands under cyclic torsional shear
Creators: name: Uthayakumar, Muthukumarasamy
Publisher: name: University of British Columbia
Year: 2008

description: Dynamic properties of soils have to be well understood in order to assure stability and acceptable performance of soil structures under seismic and wave loadings. It has been found the two important dynamic properties - shear modulus and damping factor are complex functions of many variables. In order to study the influence of various factors on shear modulus and damping factor, drained cyclic torsion shear tests were carried out in the hollow cylinder torsion device using medium Ottawa A S T M C-109 sand. Effects of shear strain amplitude, stress history, effective mean normal stress (σ'm = l/3(σ-'1 +σ'2 + σ'3)), principal effective stress ratio (R = σ1/σ3), intermediate principal stress parameter (b = σ2 —σ3)/(σ1 — σ-3)), void ratio, number of cycles of loading are some of the factors studied in this thesis. During the application of cyclic shear stress σ'm ,R and b were kept constant at pre-selected values for each test. This technique allows to study the effect cr'm, R and b independently. For example, the effect of R on dynamic properties can be isolated by a series of tests on specimens that have identical σ'm and b but different levels of R and all parameters σ'm, R and b are held constant during cyclic shear application. It is shown that shear modulus increases with number of cycles of a constant amplitude cyclic shear stress when the induced shear strain is higher than a certain threshold value. The damping, however, decreases with number of cycles even at strain amplitudes less than this threshold value. There is also a threshold value of shear strain below which zero volumetric strain occurs due to cyclic shear loading, and hence no pore pressure would develop if cyclic loading was undrained. Effects of stage testing and small strain history on dynamic properties is shown to be insignificant. With decrease of void ratio, shear modulus increases and damping factor decreases. It is shown that for a given b, the void ratio factor F(e) = (2.17 —e)² ( l + e), collapses the modulus degradation curves obtained at different void ratios in to a single curve. For a given initial stress state and shear strain amplitude, shear modulus obtained at different R levels do not show any significant difference when R < 3. Damping factors, however, seems to be unaffected by the change in R at all R levels. When R < 3, shear moduli in triaxial extension condition (b = 1) are found to be less than those in triaxial compression condition (b = 0) and damping factors for b = 1 are higher than those for b = 0. Both triaxial compression and extension state of loadings yielded same values shear modulus and damping factors at large amplitude of shear strain at R = 3. Test results indicate that when b < 1, the dynamic properties are independent of intermediate principal stress. Effects of stress history due to decrease in R from 3 to 2, is significant only in the small strain range, and as the strain level increase, the effects of stress history diminishes.
A Flow-Based Neural Network for Time Domain Speech Enhancement

description: Speech enhancement involves the distinction of a target speech signal from an intrusive background. Although generative approaches using Variational Autoencoders or Generative Adversarial Networks (GANs) have increasingly been used in recent years, normalizing flow (NF) based systems are still scarse, despite their success in related fields. Thus, in this paper we propose a NF framework to directly model the enhancement process by density estimation of clean speech utterances conditioned on their noisy counterpart. The WaveGlow model from speech synthesis is adapted to enable direct enhancement of noisy utterances in time domain. In addition, we demonstrate that nonlinear input companding benefits the model performance by equalizing the distribution of input samples. Experimental evaluation on a publicly available dataset shows comparable results to current state-of-the-art GAN-based approaches, while surpassing the chosen baselines using objective evaluation metrics.

Planet formation around low mass stars: the moving snow line and super-Earths

description: We develop a semi-analytic model for planet formation during the pre-main sequence contraction phase of a low mass star. During this evolution, the stellar magnetosphere maintains a fixed ratio between the inner disk radius and the stellar radius. As the star contracts at constant effective temperature, the `snow line', which separates regions of rocky planet formation from regions of icy planet formation, moves inward. This process enables rapid formation of icy protoplanets that collide and merge into super-Earths before the star reaches the main sequence. The masses and orbits of these super-Earths are consistent with super-Earths detected in recent microlensing experiments.

description: Recent advances in 3D imaging technologies provide novel insights to researchers and reveal finer and more detail of examined specimen, especially in the biomedical domain, but also impose huge challenges regarding scalability for automated analysis algorithms due to rapidly increasing dataset sizes. In particular, existing research towards automated vessel network analysis does not consider memory requirements of proposed algorithms and often generates a large number of spurious branches for structures consisting of many voxels. Additionally, very often these algorithms have further restrictions such as the limitation to tree topologies or relying on the properties of specific image modalities. We present a scalable pipeline (in terms of computational cost, required main memory and robustness) that extracts an annotated abstract graph representation from the foreground segmentation of vessel networks of arbitrary topology and vessel shape. Only a single, dimensionless, a-priori determinable parameter is required. By careful engineering of individual pipeline stages and a novel iterative refinement scheme we are, for the first time, able to analyze the topology of volumes of roughly 1TB on commodity hardware. An implementation of the presented pipeline is publicly available in version 5.1 of the volume rendering and processing engine Voreen (https://www.uni-muenster.de/Voreen/).
A Mobile Framework for Real-Time EV Charging Management and Optimization
Creators: name: University of Mumbai
Publisher: name: Zenodo
Year: 2025

description: The rapid adoption of electric vehicles (EVs) has created significant challenges related to charging infrastructure accessibility, utilization efficiency, and user experience. This paper presents a comprehensive mobile application framework, "Smart EV Connect," designed to address these challenges through intelligent location services, energy consumption prediction, real-time availability tracking, and reservation capabilities. The application employs a combination of geospatial algorithms, machine learning-based energy prediction models, and distributed database architecture to deliver a seamless user experience. Validation tests conducted with 150 EV users across urban and suburban environments demonstrate a 37% reduction in charging anxiety and a 42% improvement in charging station utilization rates. The system architecture provides extensibility for integration with smart grid infrastructure and vehicle-to-grid (V2G) technologies, positioning it as a valuable component in the evolving EV ecosystem.
Pauli graph and finite projective lines/geometries

description: The commutation relations between the generalized Pauli operators of N-qudits (i. e., N p-level quantum systems), and the structure of their maximal sets of commuting bases, follow a nice graph theoretical/geometrical pattern. One may identify vertices/points with the operators so that edges/lines join commuting pairs of them to form the so-called Pauli graph P_{p^N} . As per two-qubits (p = 2, N = 2) all basic properties and partitionings of this graph are embodied in the geometry of the symplectic generalized quadrangle of order two, W(2). The structure of the two-qutrit (p = 3, N = 2) graph is more involved; here it turns out more convenient to deal with its dual in order to see all the parallels with the two-qubit case and its surmised relation with the geometry of generalized quadrangle Q(4, 3), the dual of W(3). Finally, the generalized adjacency graph for multiple (N > 3) qubits/qutrits is shown to follow from symplectic polar spaces of order two/three. The relevance of these mathematical concepts to mutually unbiased bases and to quantum entanglement is also highlighted in some detail.

Simulations of starspot anomalies within TESS exoplanetary transit light curves -- II

description: We determine the starspot detection rate in exoplanetary transit light curves for M and K dwarf stars observed by the Transiting Exoplanet Survey Satellite (TESS) using various starspot filling factors and starspot distributions. We used $3.6\times10^9$ simulations of planetary transits around spotted stars using the transit-starspot model \prism. The simulations cover a range of starspot filling factors using one of three distributions: uniform, polar-biased, and mid-latitude. After construction of the stellar disc and starspots, we checked the transit cord for starspots and examined the change in flux of each starspot to determine whether or not a starspot anomaly would be detected. The results were then compared to predicted planetary detections for TESS. The results show that for the case of a uniform starspot distribution, $64\pm9$ M dwarf and $23\pm4$ K dwarf transit light curves observed by TESS will contain a starspot anomaly. This reduces to $37\pm6$ M dwarf and $12\pm2$ K dwarf light curves for a polar-biased distribution and $47\pm7$ M dwarf and $21\pm4$ K dwarf light curves for a mid-latitude distribution. Currently there are only 17 M dwarf and 10 K dwarf confirmed planetary systems from TESS, none of which are confirmed as showing starspot anomalies. All three starspot distributions can explain the current trend. However, with such a small sample, a firm conclusion can not be made at present. In the coming years when more TESS M and K dwarf exoplanetary systems have been detected and characterised, it will be possible to determine the dominant starspot distribution.

Construction of chaotic regions for Duffing’s equation with a quadric term
Creators: name: Chen, Xiong
Publisher: name: University of British Columbia
Year: 2008

description: Non-linear oscillators can exhibit non-periodic responses under periodic excitation. A point in the parametric space is said to be within a chaotic region if the response under periodic excitation is chaotic. The Lyapunov exponent analysis is developed herein to construct chaotic regions for Duffing's equation. Structural background of Duffing's equation is given. Phase plane and Poincare plots are made to check some questionable chaotic points in the parametric space. In order to help understand chaotic behaviour, bifurcation and stability analyses are presented. Theoretical and heuristic criteria are also discussed for specific cases, and plotted to compare with numerical results. Numerical results are obtained for Duffing's equation with two kinds of quadratic terms, (1) X|X| term, (2) X2 term. Some other cases are also included in order to compare with previous work. In general, good agreement is obtained.

The classification of traveling wave solutions and superposition of multi-solutions to Camassa-Holm equation with dispersion

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)

description: Under the traveling wave transformation, Camassa-Holm equation with dispersion is reduced to an integrable ODE whose general solution can be obtained using the trick of one-parameter group. Furthermore combining complete discrimination system for polynomial, the classifications of all single traveling wave solutions to the Camassa-Holm equation with dispersion is obtained. In particular, an affine subspace structure in the set of the solutions of the reduced ODE is obtained. More general, an implicit linear structure in Camassa-Holm equation with dispersion is found. According to the linear structure, we obtain the superposition of multi-solutions to Camassa-Holm equation with dispersion.
Far-UV Fe Emission as Proxy of Eddington Ratios
Creators: name: Zheng, Wei
Publisher: name: arXiv
Year: 2021
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: The Eddington ratio is a key parameter that governs the diversity of quasar properties. It can be scaled with a strong anti-correlation between optical Fe II and [O III] emission. In search of such indicators in the far-UV band, the HST far-UV spectra of 150 low-redshift quasars are analyzed in combination with their optical SDSS counterparts. The strength of Fe II+Fe III 1123 emission is significantly correlated with that of optical Fe II. A moderate correlation may also exist between Fe II 1071 and optical Fe II. The finding opens the possibility that far-UV Fe II emission may serve as a new gauge of the Eddington ratios. The high- and low-ionization lines in the far-UV band display different patterns: for the quasars with higher Eddington ratios, the low-ionization UV lines are stronger, and the high-ionization lines are broader and weaker.

We calculate atomic spin flip lifetimes and compare the strength of the Casimir-Polder potential with the magnetic trapping potential. Our analysis indicates that the Casimir-Polder force is the dominant loss mechanism and we compute the minimum distance to the carbon nanotube at which an atom can be trapped.

description: The estimation of the polarization $P$ of extragalactic compact sources in Cosmic Microwave Background images is a very important task in order to clean these images for cosmological purposes -- as, for example, to constrain the tensor-to-scalar ratio of primordial fluctuations during inflation -- and also to obtain relevant astrophysical information about the compact sources themselves in a frequency range, $ν\sim 10$--$200$ GHz, where observations have only very recently started to be available. In this paper we propose a Bayesian maximum a posteriori (MAP) approach estimation scheme which incorporates prior information about the distribution of the polarization fraction of extragalactic compact sources between 1 and 100 GHz. We apply this Bayesian scheme to white noise simulations and to more realistic simulations that include CMB intensity, Galactic foregrounds and instrumental noise with the characteristics of the QUIJOTE experiment Wide Survey at 11 GHz. Using these simulations, we also compare our Bayesian method with the frequentist Filtered Fusion method that has been already used in WMAP data and in the \emph{Planck} mission. We find that the Bayesian method allows us to decrease the threshold for a feasible estimation of $P$ to levels below $\sim 100$ mJy (as compared to $\sim 500$ mJy that was the equivalent threshold for the frequentist Filtered Fusion). We compare the bias introduced by the Bayesian method and find it to be small in absolute terms. Finally, we test the robustness of the Bayesian estimator against uncertainties in the prior and in the flux density of the sources. We find that the Bayesian estimator is robust against moderate changes in the parameters of the prior and almost insensitive to realistic errors in the estimated photometry of the sources.

description: In natural auditory environments, acoustic signals originate from the temporal superimposition of different sound sources. The problem of inferring individual sources from ambiguous mixtures of sounds is known as blind source decomposition. Experiments on humans have demonstrated that the auditory system can identify sound sources as repeating patterns embedded in the acoustic input. Source repetition produces temporal regularities that can be detected and used for segregation. Specifically, listeners can identify sounds occurring more than once across different mixtures, but not sounds heard only in a single mixture. However, whether such a behaviour can be computationally modelled has not yet been explored. Here, we propose a biologically inspired computational model to perform blind source separation on sequences of mixtures of acoustic stimuli. Our method relies on a somatodendritic neuron model trained with a Hebbian-like learning rule which can detect spatio-temporal patterns recurring in synaptic inputs. We show that the segregation capabilities of our model are reminiscent of the features of human performance in a variety of experimental settings involving synthesized sounds with naturalistic properties. Furthermore, we extend the study to investigate the properties of segregation on task settings not yet explored with human subjects, namely natural sounds and images. Overall, our work suggests that somatodendritic neuron models offer a promising neuro-inspired learning strategy to account for the characteristics of the brain segregation capabilities as well as to make predictions on yet untested experimental settings.

description: Right-handed neutrinos offer an elegant solution to two well established phenomena beyond the Standard Model (SM) - masses and oscillations of neutrinos, as well as the baryon asymmetry of the Universe. It is also a minimalistic solution since it requires only singlet Majorana fermions to be added to the SM particle content. If these fermions are nearly degenerate, the mass scale of right-handed neutrinos can be very low and accessible by the present and planned experiments. There are at least two well studied mechanisms of the low-scale leptogenesis: baryogenesis via oscillations and resonant leptogenesis. These two mechanisms were often considered separate, but they can in fact be understood as two different regimes of one and the same mechanism, described by a unique set of quantum kinetic equations. In this work we show, using a unified description based on quantum kinetic equations, that the parameter space of these two regimes of low-scale leptogenesis significantly overlap. We present a comprehensive study of the parameter space of the low-scale leptogenesis with the mass scale ranging from $0.1$ GeV to $\sim 10^6$ GeV. The unified perspective of this work reveals the synergy between intensity and energy frontiers in the quest for heavy Majorana neutrinos.

description: Many novel quantum phenomena emerge in non-equilibrium relativistic quantum matter under extreme conditions such as strong magnetic fields and rotations. The quantum kinetic theory based on Wigner functions in quantum field theory provides a powerful and effective microscopic description of these quantum phenomena. In this article we review some of recent advances in the quantum kinetic theory and its applications in describing these quantum phenomena.

description: Η παρούσα διατριβή έχει ως γενικό σκοπό στο να δώσει απάντηση στα παρακάτω ερωτήματα : 1. κατά πόσο ο κάθε μαθητής γνωρίζει την αδυναμία που παρουσιάζει ο παγκόσμιος χάρτης στη σωστή απεικόνιση της γήινης επιφάνειας 2. αν μπορεί να εντοπίσει τις περιοχές του χάρτη που παρουσιάζουν έντονη παραμόρφωση στο σχήμα και τις εκτάσεις σε σχέση με το πραγματικό σχήμα της υδρογείου 3. ποια χαρτογραφική προβολή μπορεί κατά την γνώμη τους να δώσει τα καλύτερα διδακτικά αποτελέσματα. Στηρίχθηκε σε τρεις(3) κλιμακωτές έρευνες που έγιναν στα σχολεία(Γυμνάσια και Δημοτικά) του Νομού Φλώρινας εξετάζοντας και μελετώντας τη διεθνή βιβλιογραφία και τις προϋπάρχουσες ερευνητικές προσπάθειες. Τα αποτελέσματα των ερευνών στηρίχθηκαν με τη βοήθεια του S.P.S.S. και αναδεικνύουν τη χαμηλή επίδοση των μαθητών στην μαθηματική γεωγραφία και ότι αυτοί είναι περισσότερο εξοικειωμένοι με τις σύμμορφες χαρτ. προβολές παρά με αυτές της ίσης έκτασης.

description: The research part of this thesis presents the realizations, the results and the conclusions of the three(3) following searching efforts : 1. in the existing situation of the cartographic material that concerns the world mao in greek school for teaching geography 2. in the existing situation of the cognitive sufficiency of students with the object of mathematic cartography of primary school 3. in cognitive sufficiency of high school students to recognize the projecting inability of the spherical earth surface on eight(8) different portrayed flat globular maps and realize the existing distortions of them. It took place in the schools of the town of Florina. We conclude that most students have the illusion that the projections that present intense distortion have also disproportion in area and they are familiarized more with conformed map projections

description: D$_2$ molecules, excited by linearly cross-polarized femtosecond extreme ultraviolet (XUV) and near-infrared (NIR) light pulses, reveal highly structured D$^+$ ion fragment momenta and angular distributions that originate from two different 4-step dissociative ionization pathways after four photon absorption (1 XUV + 3 NIR). We show that, even for very low dissociation kinetic energy release $\le$~240~meV, specific electronic excitation pathways can be identified and isolated in the final ion momentum distributions. With the aid of {\it ab initio} electronic structure and time-dependent Schrödinger equation calculations, angular momentum, energy, and parity conservation are used to identify the excited neutral molecular states and molecular orientations relative to the polarization vectors in these different photoexcitation and dissociation sequences of the neutral D$_2$ molecule and its D$_2^+$ cation. In one sequential photodissociation pathway, molecules aligned along either of the two light polarization vectors are excluded, while another pathway selects molecules aligned parallel to the light propagation direction. The evolution of the nuclear wave packet on the intermediate \Bstate electronic state of the neutral D$_2$ molecule is also probed in real time.

description: In 2019, the Research and Education Collaborative Occultation Network (RECON) obtained multiple-chord occultation measurements of two centaur objects: 2014 YY$_{49}$ on 2019 January 28 and 2013 NL$_{24}$ on 2019 September 4. RECON is a citizen-science telescope network designed to observe high-uncertainty occultations by outer solar system objects. Adopting circular models for the object profiles, we derive a radius $r=16^{+2}_{-1}$km and a geometric albedo $p_V=0.13^{+0.015}_{-0.024}$ for 2014 YY$_{49}$, and a radius $r=66 ^{+5}_{-5}$km and geometric albedo $p_V = 0.045^{+0.006}_{-0.008}$ for 2013 NL$_{24}$. To the precision of these measurements, no atmosphere or rings are detected for either object. The two objects measured here are among the smallest distant objects measured with the stellar occultation technique. In addition to these geometric constraints, the occultation measurements provide astrometric constraints for these two centaurs at a higher precision than has been feasible by direct imaging. To supplement the occultation results, we also present an analysis of color photometry from the Pan-STARRS surveys to constrain the rotational light curve amplitudes and spectral colors of these two centaurs. We recommend that future work focus on photometry to more deliberately constrain the objects' colors and light curve amplitudes, and on follow-on occultation efforts informed by this astrometry.

description: The acoustic detection method is a promising option for future neutrino telescopes operating in the ultra-high energy regime. It utilises the effect that a cascade evolving from a neutrino interaction generates a sound wave, and is applicable in different target materials like water, ice and salt. Described here are the developments in and the plans for the research on acoustic particle detection in water performed by the ANTARES group at the University of Erlangen within the framework of the ANTARES experiment in the Mediterranean Sea. A set of acoustic sensors will be integrated into this optical neutrino telescope to test acoustic particle detection methods and perform background studies.

description: We describe how to construct the dynamics of relativistic particles following, either timelike or null curves, by means of an auxiliary variables method instead of the standard theory of deformations for curves. There are interesting physical particle models governed by actions that involve higher order derivatives of the embedding functions of the worldline. We point out that the mechanical content of such models can be extracted wisely from a lower order action, which can be performed by implementing in the action a finite number of constraints that involve the geometrical relationship structures inherent to a curve and by using a covariant formalism. We emphasize our approach for null curves. For such systems, the natural time parameter is a pseudo-arclength whose properties resemble those of the standard proper time. We illustrate the formalism by applying it to some models for relativistic particles.
