description: Η παρούσα διπλωματική εργασία στοχεύει στην ανάπτυξη ενός ψηφιακού συστήματος, σε περιβάλλον Python, που υλοποιεί μοντέλα μετάδοσης θερμότητας μόνιμης και μη-μόνιμης αγωγής σε μορφή υπολογιστικών ασκήσεων. Σκοπός του συστήματος αυτού είναι η δημιουργία ενός ψηφιακού εργαστηρίου (Virtual Lab) στα πλαίσια του μαθήματος “Μετάδοση Θερμότητας” το οποίο δίνει την ικανότητα στους φοιτητές να εμπεδώσουν το θεωρητικό υπόβαθρο του μαθήματος μέσα από μία σειρά πρακτικών εφαρμογών.
Ένα ψηφιακό εργαστήριο είναι στην ουσία ένα δυναμικό εργαλείο που μιμείται την πραγματικότητα και καθίσταται πιο ευέλικτο από ένα συμβατικό εργαστήριο, χάρη στην άμεση αλληλεπίδραση, την ασφάλεια των φοιτητών και στη χρήση οπτικών ή γραφικών μέσων για την περιγραφή περίπλοκων εννοιών, αποσκοπώντας στην ένταξη της διδακτικής διαδικασίας στην νοοτροπία της 4ης Βιομηχανικής “Επανάστασης”. Συνήθως, δημιουργούνται για να αντικαταστήσουν ακριβές μηχανές ή μηχανήματα που δεν είναι εφικτό είτε να κατασκευαστούν είτε να κατοχυρωθούν, όπως επίσης και τον περίπλοκο χειρισμό τους καθώς επίσης έχουν την ικανότητα προσομοίωσης σύνθετων επιστημονικών διεργασιών, όντας γνώσεις που δεν μπορεί να προσφέρει ένα συμβατικό εργαστήριο.
Η ανάπτυξη του παρόντος ψηφιακού συστήματος θα πραγματοποιηθεί με τη χρήση συγκεκριμένων εργαλείων:
Ø Αριθμητικές μεθόδους: για την διακριτοποίηση των μερικών διαφορικών εξισώσεων στα πλαίσια της μετά-δοσης θερμότητας.
Ø Αλγόριθμους μετάδοσης θερμότητας: για την παραμετροποίηση/μοντελοποίηση και την εφαρμογή τους στο σύστημα.
Ø Python 3.8 & Qt Designer: για την ανάπτυξη/δημιουργία γραφικού περιβάλλοντος διεπαφής χρήστη – συ-στήματος (Graphical User Interface – GUI).

description: The complex Langevin method in conjunction with the gauge cooling is applied to the two-dimensional lattice $SU(2)$ Yang-Mills theory that is analytically solvable. We obtain strong numerical evidence that at large Langevin time the expectation value of the plaquette variable converges, but to a wrong value when the complex phase of the gauge coupling is large.

A Comparison of the Ocean Microbarom Recorded on the Ground and in the Stratosphere
Creators: name: Bowman, D.C.
name: Lees, J.M.
Publisher: name: Blackwell Publishing Ltd
Year: 2017

description: The, ocean microbarom is an acoustic signal generated via nonlinear interaction of ocean surface waves. It can propagate for thousands of kilometers and represent a significant infrasonic noise source for ground infrasound stations across the globe. However, wind noise often compromises detections at ground stations. Furthermore, the microbarom may travel in elevated acoustic ducts that do not transmit enough energy for detections on ground stations. Here the presence of the ocean microbarom on two high-altitude balloon flights is investigated. A spectral peak consistent with the microbarom was observed on sensors in the stratosphere but not on those deployed on the ground near the flight path of the balloon. This is probably due to an elevated acoustic duct and/or a superior signal-to-noise ratio in the stratosphere. Thus, microbarom activity quantified solely with ground-based sensors may underestimate the occurrence of the phenomenon. However, high levels of interference from flight system electronics and/other other payloads may have obscured other microbarom episodes during the balloon deployments.
A coupled-trajectory quantum-classical approach to decoherence in non-adiabatic processes

description: We present a novel quantum-classical approach to non-adiabatic dynamics, deduced from the coupled electronic and nuclear equations in the framework of the exact factorization of the electron-nuclear wave function. The method is based on the quasi-classical interpretation of the nuclear wave function, whose phase is related to the classical momentum and whose density is represented in terms of classical trajectories. In this approximation, electronic decoherence is naturally induced as effect of the coupling to the nuclei and correctly reproduces the expected quantum behaviour. Moreover, the splitting of the nuclear wave packet is captured as consequence of the correct approximation of the time-dependent potential of the theory. This new approach offers a clear improvement over Ehrenfest-like dynamics. The theoretical derivation presented in the Letter is supported by numerical results that are compared to quantum mechanical calculations.

description: Der demografische Wandel, das schnelle Wachstum von Unternehmen und der informationstechnologische Fortschritt beeinflussen den Arbeitsalltag im Rechnungswesen in einem Ausmaß und einer Geschwindigkeit, welche die Führungskräfte und MitarbeiterInnen der Buchhaltungsabteilungen vor große Herausforderungen stellt. Betrachtet man die drei eben genannten Faktoren kontextuell, liegt die Schlussfolgerung nahe, neue Technologien künftig auch verstärkt in der Finanzbuchhaltung für sich arbeiten zu lassen, um die Humanressourcen einerseits zu schonen und andererseits für das Unternehmen gewinnbringender einzusetzen. Es ist erforderlich, Fachkräfte des Rechnungswesens von repetitiven Routineaufgaben zu befreien und sie mit fachlich anspruchsvolleren Aufgaben zu betrauen. Im Rahmen dieser Master Thesis wurden jene für die Debitoren- und Kreditorenbuchhaltung in Frage kommenden Automatisierungstechnologien erläutert und mit den konkreten buchhalterischen Prozessen verknüpft. Es galt die Einsatzmöglichkeiten der Automatisierungstools, deren Voraussetzungen, Erfolgsfaktoren und Hürden im Rahmen der Implementierung sowie die dadurch bedingten Vor- und Nachteile in der Anwendung zu erörtern. Gemäß eines qualitativen Forschungszuganges wurden im Anschluss an den theoretischen Teil zehn ExpertInnen der Bereiche Finanzbuchhaltung, Digitalisierung, Finanzprozessoptimierung, Produktentwicklung und Consulting im ERP-Bereich interviewt. Die Auswertung aller theoretisch und empirisch gewonnenen Informationen ergab, dass die Prozessautomatisierung in der Finanzbuchhaltung einen logischen und notwendigen Schritt für Unternehmen darstellt. Die Chancen überwiegen jene Risiken, die nicht mittels penibler Vorbereitung vermieden werden können, deutlich. Insbesondere der Effizienzgewinn und die damit einhergehende Arbeitszeitersparnis überzeugen in ökonomischer Hinsicht von Automatisierungstechnologien innerhalb von ERP-Systemen, API, RPA, OCR und der Rechnungs- und Datenübertragung in standardisierter Form auf XML-Basis. Dementsprechend wird sich das Berufsbild des Buchhalters/der Buchhalterin in den nächsten Jahren merklich verändern. Aufgrund der aktuell stattfindenden Entwicklungen im KI-Bereich wird sich der Kreis der technologischen Möglichkeiten zur Prozessautomatisierung aller Wahrscheinlichkeit nach erweitern.

description: We have studied the plasmonic properties of aperiodic arrays of identical nanoparticles (NPs) formed by two opposite and equal graded-chains (a chain where interactions change gradually). We found that these arrays concentrate the external electromagnetic fields even in the long wavelength limit. The phenomenon was understood by identifying the system with an effective cavity where plasmonics excitations are trapped between effective band edges, resulting from the change of passband with NP's position. Dependence of excitation concentration on several system's parameter was also assessed. This includes, different gradings as well as NP's couplings, damping, and resonant frequencies. In the spirit of the scaling laws in condensed matter physics, we developed a theory that allows us to rationalize all these system's parameters into universal curves. The theory is quite general and can also be used on many other situations (different arrays for example). Additionally, we also provided an analytical solution, in the tight-binding limit, for the plasmonic response of homogeneous linear chains of NPs illuminated by a plane wave. Our results can find applications on sensing, near field imaging, plasmon-enhanced photodetectors, as well as to increase solar cell efficiency.

description: The concept of an acoustical analog of the optical laser has been developed recently both in theoretical as well as experimental works. We discuss here a model of a coherent phonon generator with a direct signature of quantum properties of the sound vibrations. The considered setup is made of a laser driven quantum dot (QD) embedded in an acoustical nanocavity. The system's dynamics is solved for a single phonon mode in the steady-state and in the strong QD-phonon coupling regime beyond the secular approximation. We demonstrate that the phonon statistics exhibits quantum features, i.e. sub-Poissonian phonon statistics.

description: Mechanisms that produce seismic and acoustic wavefields near rivers are poorly understood because of a lack of observations relating temporally dependent river conditions to the near-river seismoacoustic fields. This controlled study at the Harry W. Morrison Dam (HWMD) on the Boise River, Idaho, explores how temporal variation in fluvial systems affects surrounding acoustic and seismic fields. Adjusting the configuration of the HWMD changed the river bathymetry and therefore the form of the standing wave below the dam. The HWMD was adjusted to generate four distinct wave regimes that were parameterized through their dimensionless Froude numbers (Fr) and observations of the ambient seismic and acoustic wavefields at the study site. To generate detectable and coherent signals, a standing wave must exceed a threshold Fr value of 1.7, where a nonbreaking undular jump turns into a breaking weak hydraulic jump. Hydrodynamic processes may partially control the spectral content of the seismic and acoustic energies. Furthermore, spectra related to reproducible wave conditions can be used to calibrate and verify fluvial seismic and acoustic models.

description: Recent decades have witnessed a sharp biodiversity decline in freshwaters due to multiple stressors. The presence of multiple stressors is expected to affect community structure and interactions in freshwater ecosystems, with subsequent functional consequences. We synthesized the state of experimental, manipulative multiple-stressor studies that focused on multispecies assemblages in freshwaters. Compared to rivers and lakes, wetland and groundwater ecosystems have received much less attention in identified multiple-stressor research. Most of the identified studies investigated combinations of abiotic stressors (e.g., nutrients, pesticides, heavy metals, warming, altered flow and sedimentation) on microbes and invertebrates while biotic stressors and vertebrates have been largely overlooked. The responses of community structure (e.g., alpha diversity, biomass, and abundance), some community/ecosystem functions (e.g., photosynthesis and autotrophic activity, leaf litter degradation), and morphological traits like body size and growth forms were frequently investigated. We observed a clear gap in biotic interactions under multiple-stressor conditions, which, although difficult to study, could impede a deeper mechanistic understanding of how multiple stressors affect freshwater assemblages and associated ecological processes. Although information on ecosystem recovery pathways following restoration is critical for freshwater management, few studies were designed to provide such information, signifying the disconnections between multiple-stressor research and environmental practice. To bridge these gaps, researchers and environmental practitioners need to work together to identify key stressors and interactions at different spatial and temporal scales and prioritize stressor management. Such collaborations will enhance the translation of multiple-stressor research into efficient management strategies to protect and restore freshwater ecosystems.

description: A recently published correlated electron pseudopotentials (CEPPs) method has been adapted for application to the 3d-transition metals, and to include relativistic effects. New CEPPs are reported for the atoms Sc$-$Fe, constructed from atomic quantum chemical calculations that include an accurate description of correlated electrons. Dissociation energies, molecular geometries, and zero-point vibrational energies of small molecules are compared with all electron results, with all quantities evaluated using coupled cluster singles doubles and triples (CCSD(T)) calculations. The CEPPs give better results in the correlated-electron calculations than Hartree-Fock-based pseudopotentials available in the literature.

Three-dimensional attenuation model of Sierra Negra Volcano, Galápagos Archipelago

Publisher: name: Blackwell Publishing Ltd
Year: 2016

description: The shallow magma system beneath Sierra Negra was imaged using attenuation tomographic methods. The t∗ spectral decay method for P wave phases was used to highlight regions of high Q-1 p which suggest the presence of magma melt. High-Q-1 p anomalies ranging from 0.005 to 0.04 are concentrated below the caldera from 0.5 to 10.5 km depths. Attenuation is sensitive to temperature and fluid presence; thus, this high attenuation is interpreted as possible zones of magma accumulation. An imaged shallow body is consistent with geodetic studies on caldera deformation that modeled a magma sill or flattopped diapir of unknown thickness at ∼1 km depth below sea level.
Imaging volcanic infrasound sources using time reversal mirror algorithm
Creators: name: Kim, K.
name: Lees, J.M.
Publisher: name: Oxford University Press
Year: 2015

description: We investigate the capability of Time Reversal Mirror (TRM) algorithm to image local acoustic sources (<3.5 km) associated with complex, sustained volcanic eruptions. Accurate source localization for volcano infrasound (low-frequency acoustic waves) is often challenging due to pronounced volcanic topography and emergent arrivals of infrasound signals. While the accuracy of the conventional approaches (e.g. triangulation and semblance method) can be severely compromised by the complex volcanic settings, a TRM-based method may have the potential to properly image acoustic sources by the use of full waveform information and numerical modelling of the time-reversed wavefield. We apply the TRM algorithm to a pyroclastic-laden eruption (sustained for ~60 s) at Santiaguito Volcano, Guatemala, and show that an ordinary TRM operation can undergo significant reduction of its focusing power due to strong topographic propagation effects (e.g. reflection and diffraction). We propose a weighted imaging condition to compensate for complicated transmission loss of the time-reversed wavefield and demonstrate that the presented condition significantly improves the focusing quality of TRM in the presence of complex topography. The consequent TRM source images exhibit remarkable agreement with the visual observation of the eruption implying that the TRM method with a proper imaging condition can be used to localize and track acoustic sources associated with complex volcanic eruptions.

Infrasound in the middle stratosphere measured with a free-flying acoustic array
Creators: name: Lees, J.M.
name: Bowman, D.C.
Publisher: name: Blackwell Publishing Ltd
Year: 2015

description: Infrasound recorded in the middle stratosphere suggests that the acoustic wavefield above the Earth's surface differs dramatically from the wavefield near the ground. In contrast to nearby surface stations, the balloon-borne infrasound array detected signals from turbulence, nonlinear ocean wave interactions, building ventilation systems, and other sources that have not been identified yet. Infrasound power spectra also bore little resemblance to spectra recorded on the ground at the same time. Thus, sensors on the Earth's surface likely capture a fraction of the true diversity of acoustic waves in the atmosphere. Future studies building upon this experiment may quantify the acoustic energy flux from the surface to the upper atmosphere, extend the capability of the International Monitoring System to detect nuclear explosions, and lay the observational groundwork for a recently proposed mission to detect earthquakes on Venus using free-flying microphones. Key Points Stratospheric infrasound is very different from infrasound recorded on ground stations Numerous broadband and narrowband signals exist in the stratosphere, some of unknown origin Acoustic networks on free floating balloons have unique advantages and disadvantages.

Acoustic source inversion to estimate volume flux from volcanic explosions

name: Lees, J.M.
name: Kim, K.
Publisher: name: Blackwell Publishing Ltd
Year: 2015

description: We present an acoustic waveform inversion technique for infrasound data to estimate volume fluxes from volcanic eruptions. Previous inversion techniques have been limited by the use of a 1-D Green's function in a free space or half space, which depends only on the source-receiver distance and neglects volcanic topography. Our method exploits full 3-D Green's functions computed by a numerical method that takes into account realistic topographic scattering. We apply this method to vulcanian eruptions at Sakurajima Volcano, Japan. Our inversion results produce excellent waveform fits to field observations and demonstrate that full 3-D Green's functions are necessary for accurate volume flux inversion. Conventional inversions without consideration of topographic propagation effects may lead to large errors in the source parameter estimate. The presented inversion technique will substantially improve the accuracy of eruption source parameter estimation (cf. mass eruption rate) during volcanic eruptions and provide critical constraints for volcanic eruption dynamics and ash dispersal forecasting for aviation safety. Application of this approach to chemical and nuclear explosions will also provide valuable source information (e.g., the amount of energy released) previously unavailable. Key Points First waveform inversion of volcano infrasound using a 3-D Green's function Strong topographic scattering must be considered for source inversion The method substantially improves the accuracy of eruption source parameter estimation.

description: Bis vor einigen Jahren noch nachrangig behandelt, ist das Thema Nachhaltigkeit auch in der Wirtschaft angekommen. Ausgehend vom Pariser Klimaabkommen im Jahr 2016 setzte die Europäische Union zahlreiche Maßnahmen, die zu einer Reduktion von Treibhausgasen beitragen sowie den Klimawandel positiv beeinflussen sollen. Mit der Einführung der EU-Taxonomie-Verordnung und der Anpassung der Richtlinie zur Nachhaltigkeitsberichterstattung kommt es zu einer signifikanten Steigerung der Relevanz von Nachhaltigkeit in der Wirtschaft. Die Unternehmungen stehen in der Umsetzung vor zahlreiche Herausforderungen. Das wissenschaftliche Ziel dieser Masterthesis ist es, die Einflüsse betrieblicher Managementsysteme sowohl auf die Erstellung der externen Finanzbericht- als auch auf die Nachhaltigkeitsberichterstattung hin zu untersuchen. Darüber hinaus werden die Auswirkungen von Managementsystemen auf die EU-Taxonomie-Verordnung betrachtet. Der spezielle Blickwinkel dieser Masterthesis bezieht sich auf die Branche der Abfallwirtschaft. Für die Erstellung des Theorieteils wurde eine umfassende Literaturrecherche durchgeführt. Hier zeigte sich sowohl die Komplexität des Themengebiets als auch der zeitlich eng bemessene Rahmen hin zum Erstanwendungszeitpunkt. Im Zuge der empirischen Forschung wurden Expertisen von Personen aus dem Fachbereich zur Thematik eingeholt. Hinterfragt wurden die Anforderungen und Herausforderungen im Zusammenhang mit der Nachhaltigkeitsberichterstellung speziell für Unternehmen der Abfallwirtschaft. Ebenfalls wurden die Wirkungsweisen aus den in der Praxis angewandten betrieblichen Managementsystemen, hinsichtlich der Erstellung des Nachhaltigkeitsberichtes hinterfragt. Die Forschungsergebnisse zeigen, dass sich die Unternehmen von der Komplexität des Berichtsumfanges durchaus besorgt äußern. Es zeigte sich darüber hinaus, dass für die Erstellung eines Nachhaltigkeitsberichtes das Mitwirken von diversen Abteilungen gefordert ist. Eine Herausforderung stellt die Datenbereitstellung dar. Eine Koordination der Daten im Rahmen eines IMS wird als vorteilhaft erachtet. Angewandte Managementsysteme liefern nach den Erkenntnissen dieser Masterthesis eine gute Datenbasis für die einzelnen Bereiche der Berichterstellung. Für die Abfallwirtschaft ergaben sich einige Themen im Hinblick auf die Berichterstellung als bedeutsam. Als ein noch ungewisser Faktor erwies sich der Umgang mit dem CO2 intensiven Fuhrpark. Positiv zeigten sich hingegen die Möglichkeiten zu neuen Geschäftsmodellen in der für die Kreislaufwirtschaft relevanten Branche.

description: A dormant indigenous bundle is an integrable projective line bundle on a proper hyperbolic curve of positive characteristic satisfying certain conditions. Dormant indigenous bundles were introduced and studied in the $p$-adic Teichmuller theory developed by S. Mochizuki. Kirti Joshi proposed a conjecture concerning an explicit formula for the degree over the moduli stack of curves of the moduli stack classifying dormant indigenous bundles. In this paper, we give a proof for this conjecture of Joshi.

description: Origanum dubium Boiss. is one of the economically important wild oregano species and it is intensely collected from the natural flora of Antalya in Turkey. Carvacrol chemotype of Origanum dubium is used mainly for essential oil production due to its high essential oil content. In this study, chemical diversity of Origanum dubium was investigated in order to develop new cultivars with improved essential oil yield and carvacrol content using clone selection method under cultivated condition. Essential oils obtained by hydrodistillation of the aerial parts of Origanum dubium were analysed by GC-MS and 24 different components were identified. In these genotypes, carvacrol was the major component and followed by p-cymene, γ–terpinene, myrcene and α-thujene. Among the selected genotypes, essential oil yields were varied between 5.0% to 14.0%; carvacrol rates were varied between 73.76% to 88.21%; and p-cymene rates were varied between 3.16% to 9.10%.

description: Non-local pairing processes at the edge of a two-dimensional topological insulator in proximity to an $s$-wave superconductor are usually suppressed by helicity. However, additional proximity of a ferromagnetic insulator can substantially influence the helical constraint and therefore open a new conduction channel by allowing for crossed Andreev reflection (CAR) processes. We show a one-to-one correspondence between CAR and the emergence of odd-frequency triplet superconductivity. Hence, non-local transport experiments that identify CAR in helical liquids yield smoking-gun evidence for unconventional superconductivity. Interestingly, we identify a setup -- composed of a superconductor flanked by two ferromagnetic insulators -- that allows us to favor CAR over electron cotunneling which is known to be a difficult but essential task to be able to measure CAR.

description: Source mechanisms of explosive volcanic eruptions are critical for understanding magmatic plumbing systems and magma transport. Tungurahua is a large andesitic stratovolcano where seismoacoustic data has been recorded over several years. In May 2010, an energetic eruption cycle began with a midsize Vulcanian explosion followed by swarms of explosive eruptions. The five-station seismoacoustic network recorded significant seismic and infrasonic signals from the explosions. Source mechanisms of 50 explosion earthquakes associated with Vulcanian explosions during this eruptive period are investigated here. The source centroid locations and geometries of explosive signals in the 10-2 s band were determined by full-waveform moment tensor inversion. The observed waveforms are well explained by a combination of volumetric moment tensor components and a single, vertical, downward force component. The source centroids are positioned about 1.5 km below and about 320 m north of the active crater. Eigenvalue and eigenvector analysis indicates that the source geometries can be described by a subhorizontal, thin ellipsoid representing a sill-like magma accumulation. Resultant source time histories show a repetitive sequence of inflation and deflation from event to event, indicating identical source processes frequently occurred over the period. The inflation/deflation in the deep source region may be the result of crack opening. Volatile bubble growth at depth opens a pathway for gases to escape and triggers shallow explosions at the summit crater. The associated downward single force is interpreted as an exchange of linear momentum between the source and the surrounding region during the escaping gas flow.
Mass Sum Rule of the Effective Action on Vacua with Broken Rigid N=1 Supersymmetry

description: We present an extension of the mass sum rule that applies to renormalizable rigid supersymmetric field theories to the case of the N=1 supersymmetric effective action (the gauged non-linear sigma model) consisting of adjoint scalar superfields and vector superfields possessing a K"ahler potential, a set of gauge coupling functions (second prepotential derivatives) and a superpotential, which respectively set their energy scales. The mass sum rule derived is valid for any vacua, including the (metastable) one of broken supersymmetry with the condensates of D-term and/or F-term. We manage to extend these analyses to the cases where superfields in (anti-)fundamental representation are present. The supertrace is shown to vanish in those cases where underlying geometry is special K"ahler and theory under concern is anomaly free. Simple phenomenological application is given, providing an upper bound for gaugino masses. We discuss that the effects of the D and/or F condensates can be represented as a set of soft breaking terms with their strengths predicted by the scales.

description: Volcan Santiaguito (Guatemala) "breathes" with extraordinary regularity as the edifice's conduit system accumulates free gas, which periodically vents to the atmosphere. Periodic pressurization controls explosion timing, which nearly always occurs at peak inflation, as detected with tiltmeters. Tilt cycles in January 2012 reveal regular 26 ± 6 min inflation/deflation cycles corresponding to at least ~101 kg/s of gas fluxing the system. Very long period (VLP) earthquakes presage explosions and occur during cycles when inflation rates are most rapid. VLPs locate ~300 m below the vent and indicate mobilization of volatiles, which ascend at ~50 m/s. Rapid gas ascent feeds pyroclast-laden eruptions lasting several minutes and rising to ~1 km. VLPs are not observed during less rapid inflation episodes; instead, gas vents passively through the conduit producing no infrasound and no explosion. These observations intimate that steady gas exsolution and accumulation in shallow reservoirs may drive inflation cycles at open-vent silicic volcanoes. Key Points Regular 26 min inflation/deflation cycles are observed at silicic volcanoInflation rates control whether volcano explodes or passively degassesLocation of gas reservoir and flux of gas through the volcano are quantified

description: Infrasound and high-speed imaging during a series of field-scale buried explosions suggest new details about the generation and radiation patterns of acoustic waves from volcanic eruptions. We recorded infrasound and high-speed video from a series of subsurface explosions with differing burial depths and charge sizes. Joint observations and modeling allow the extraction of acoustic energy related to the magnitude of initial ground deformation, the contribution of gas breakout, and the timing of the fallback of displaced material. The existence and relative acoustic amplitudes of these three phases depended on the size and depth of the explosion. The results motivate a conceptual model that relates successive contributions from ground acceleration, gas breakout, and spall fallback to the acoustic amplitude and waveform characteristics of buried explosions. We place the literature on infrasound signals at Santiaguito Volcano, Guatemala, and Sakurajima and Suwonosejima Volcanoes, Japan, in the context of this model.

description: We report a combined experimental and simulation study of deformation-induced diffusion in compacted two-dimensional amorphous granular pillars, in which thermal fluctuations play negligible role. The pillars, consisting of bidisperse cylindrical acetal plastic particles standing upright on a substrate, are deformed uniaxially and quasistatically by a rigid bar moving at a constant speed. The plastic flow and particle rearrangements in the pillars are characterized by computing the best-fit affine transformation strain and non-affine displacement associated with each particle between two stages of deformation. The non-affine displacement exhibits exponential crossover from ballistic to diffusive behavior with respect to the cumulative deviatoric strain, indicating that in athermal granular packings, the cumulative deviatoric strain plays the role of time in thermal systems and drives effective particle diffusion. We further study the size-dependent deformation of the granular pillars by simulation, and find that different-sized pillars follow self-similar shape evolution during deformation. In addition, the yield stress of the pillars increases linearly with pillar size. Formation of transient shear lines in the pillars during deformation becomes more evident as pillar size increases. The width of these elementary shear bands is about twice the diameter of a particle, and does not vary with pillar size.
