Snapping and Fluttering of Elastic Rods
Creators: name: Cazzolli, Alessandro
Publisher: name: Universit� degli studi di Trento
Year: 2020

description: The exact solutions for planar rods undergoing large rotations and subject to kinematically controlled ends are presented in the first part of the thesis. In particular, the equilibrium equations for a rod subject to Dirichlet boundary conditions and to isoperimetric constraints are derived through variational principles for both the Euler's elastica and the Reissner beam, while the related closed-form solutions are obtained in terms of the Jacobi elliptic functions. The study of stability of the Euler's elastica is addressed in the second part of the thesis through a modified version of the conjugate points method, thus disclosing the existence of a universal snap surface that represents the whole set of "saddle points" of the total potential energy, and therefore corresponding to snapping configurations. These theoretical findings allow for the prediction of snapping instabilities along any equilibrium path involving variations in the boundary conditions and are confirmed by numerical and experimental data. The universal snap surface is also exploited towards the realization of the elastica catastrophe machine, as the first extension of the classical Zeeman's machine to continuous elastic elements. Two families of the elastica catastrophe machine are presented and the theoretical model is fully validated through a prototype designed and tested at the Instability Lab of the University of Trento. Finally, the equations of motion of a pre-stressed planar rod and of its discretized counterpart subject to non-holonomic constraints are obtained in the last part. The analysis of the linearized stability surprisingly proves the existence of flutter instabilities despite the conservative nature of the considered systems. Moreover, Hopf bifurcations and destabilization paradoxes in the presence of dissipative forces are found. The non-linear equations of the proposed discretized model are also numerically solved, thus confirming the predicted stability properties and revealing the birth of periodic stable solutions.

description: We mainly study the block-coherence measures based on resource theory of block-coherence and the coherence measures based on positive-operator-valued measures (POVM). Several block-coherence measures including a block-coherence measure based on maximum relative entropy, the one-shot block coherence cost under the maximally block-incoherent operations, and a coherence measure based on coherent rank have been introduced and the relationships between these block-coherence measures have been obtained. We also give the definition of the maximally block-coherent state and describe the deterministic coherence dilution process by constructing block-incoherent operations. Based on the POVM coherence resource theory, we propose a POVM-based coherence measure by using the known scheme of building POVM-based coherence measures from block-coherence measures, and the one-shot block coherence cost under the maximally POVM-incoherent operations. The relationship between the POVM-based coherence measure and the one-shot block coherence cost under the maximally POVM-incoherent operations is analysed.

description: We investigate the outflux of ions through the channels in a cell membrane. The channels undergo an open/close cycle according to a periodic schedule. Our study is based both on theoretical considerations relying on homogenization theory, and on Monte Carlo numerical simulations. We examine the onset of a limiting boundary behavior characterized by a constant ratio between the outflux and the local density, in the thermodynamics limit. The focus here is on the issue of selectivity, that is on the different behavior of the ion currents through the channel in the cases of the selected and non-selected species.

A digital method to calculate the true areas of sunspot groups
Creators: name: Cakmak, H.
Publisher: name: arXiv
Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The areas of sunspots are the most prominent feature of the development of sunspot groups. Since the size of sunspot areas depend on the strength of the magnetic field, accurate measurements of these areas are important. In this study, a method which allows to measure true areas of the sunspots is introduced. A Stonyhurst disk is created by using a computer program and is coincided with solar images. By doing this, an accurate heliographic coordinate system is formed. Then, the true area of the whole sunspot group is calculated in square degrees with the aid of the heliographic coordinates of each picture element forming the image of the sunspot group. This technique's use is not limited with sunspot areas only. The areas of the flare and filaments observed on the chromospheric disk can also be calculated with the same method. In addition to this, it is possible to calculate the area of any occurrence on the solar disk, whether it is related to an activity or not.

description: Electronic structures of single crystalline black phosphorus were studied by state-of-art angleresolved photoemission spectroscopy. Through high resolution photon energy dependence measurements, the band dispersions along out-of-plane and in-plane directions are experimentally determined. The electrons were found to be more localized in the ab-plane than that is predicted in calculations. Beside the kz-dispersive bulk bands, resonant surface state is also observed in the momentum space. Our finds strongly suggest that more details need to be considered to fully understand the electronic properties of black phosphorus theoretically.

description: How and to what extent will new activities spread through social ties? Here, we develop a more sophisticated framework than the standard mean-field approach to describe the diffusion dynamics of multiple activities on complex networks. We show that the diffusion of multiple activities follows a saddle path and can be highly unstable. In particular, when the two activities are sufficiently substitutable, either of them would dominate the other by chance even if they are equally attractive ex ante. When such symmetry-breaking occurs, any average-based approach cannot correctly calculate the Nash equilibrium - the steady state of an actual diffusion process.

description: Resonance chains have been observed in many different physical and mathematical scattering problems. Recently numerical studies linked the phenomenon of resonances chains to an approximate clustering of the length spectrum on integer multiples of a base length. A canonical example of such a scattering system is provided by 3-funneled hyperbolic surfaces where the lengths of the three geodesics around the funnels have rational ratios. In this article we present a mathematical rigorous study of the resonance chains for these systems. We prove the analyticity of the generalized zeta function which provide the central mathematical tool for understanding the resonance chains. Furthermore we prove for a fixed ratio between the fun- nel lengths and in the limit of large lengths that after a suitable rescaling, the resonances in a bounded domain align equidistantly along certain lines. The position of these lines is given by the zeros of an explicit polynomial which only depends on the ratio of the funnel lengths.

description: The chondrocranium is the cartilage component of the vertebrate braincase. Among jawed vertebrates it varies greatly in structure, mineralisation, and in the extent to which it is replaced by bone during development. In mammals, birds, and some bony fish, most of the chondrocranium is replaced by bone whereas in lizards, amphibians, and chondrichthyan fish it may remain a significant part of the braincase complex in adulthood. To what extent this variation relates to differences in skull biomechanics is poorly understood. However, there have been examinations of chondrocranium histology, in vivo strain, and impact on rostrum growth following partial removal of the chondrocranium. These studies have led to suggestions that the chondrocranium may provide structural support or serve to dampen external loads. Advances in computing-power have also facilitated an increase in the number of three-dimensional computer-based models. These models can be analysed (in silico) to test specific biomechanical hypotheses under specified loading conditions. However, representing the material properties of cartilage is still problematic because these properties differ according to the speed and direction of loading. The relationship between stress and strain is also non-linear. Nevertheless, analyses to date suggest that the chondrocranium does not provide a vertical support in lizards but it may serve to absorb some loads in humans. We anticipate that future models will include ever more detailed representations of the loading, anatomy, and material properties, in tandem with rigorous forms of model validation. However, comparison among a wider range of vertebrate subjects should also be pursued, in particular larvae, juveniles, and very small adult animals.

description: When adhesive elastomeric materials slide over hard rough surfaces at low velocities, there are two primary dissipative mechanisms that control how friction changes with sliding velocity: viscoelastic dissipation and adhesive dissipation. To distinguish the contribution of these dissipative mechanisms we have measured frictional shear stresses for crosslinked polydimethylsiloxane (PDMS) on three different rough surfaces of similar surface chemistry across nearly six decades of sliding velocity. The results show that the observed friction is dominated by adhesive dissipation, rather than viscoelastic dissipation. Prior models for elastomer friction assume that roughness only influences adhesive dissipation via the amount of contact area; by contrast, we find that the roughness-induced oscillations occurring across all length scales from macroscopic to atomic influence the molecular processes governing the adhesive dissipation. While it was previously known that roughness-induced oscillations affected the viscoelastic dissipation; this is the first demonstration that these oscillations also control the behavior of the adhesive component of friction. Finally, while theory predicts that rough friction should be independent of elastic modulus ($E'$), we show that a strong dependence on modulus, with the frictional shear stress scaling as $E'^{1/2}$. When analyzed in this way, data from four different moduli and three different roughnesses collapse onto a universal curve to describe the velocity-dependent friction of soft materials. Taken together, this investigation sheds new light on the adhesive component of friction, and how it depends on the roughness and stiffness of the materials.

description: Executing operational processes generates event data, which contain information on the executed process activities. Process mining techniques allow to systematically analyze event data to gain insights that are then used to optimize processes. Visual analytics for event data are essential for the application of process mining. Visualizing unique process executions -- also called trace variants, i.e., unique sequences of executed process activities -- is a common technique implemented in many scientific and industrial process mining applications. Most existing visualizations assume a total order on the executed process activities, i.e., these techniques assume that process activities are atomic and were executed at a specific point in time. In reality, however, the executions of activities are not atomic. Multiple timestamps are recorded for an executed process activity, e.g., a start-timestamp and a complete-timestamp. Therefore, the execution of process activities may overlap and, thus, cannot be represented as a total order if more than one timestamp is to be considered. In this paper, we present a visualization approach for trace variants that incorporates start- and complete-timestamps of activities.

description: Compartmental epidemic models have been widely used for predicting the course of epidemics, from estimating the basic reproduction number to guiding intervention policies. Studies commonly acknowledge these models' assumptions but less often justify their validity in the specific context in which they are being used. Our purpose is not to argue for specific alternatives or modifications to compartmental models, but rather to show how assumptions can constrain model outcomes to a narrow portion of the wide landscape of potential epidemic behaviors. This concrete examination of well-known models also serves to illustrate general principles of modeling that can be applied in other contexts.

description: Properties of the quartz crystal blank of a resonator is assumed homogeneous, uniform, and perfect in design, manufacturing, and applications. As end products, quartz crystal resonators are frequently exposed to gases and liquids which can cause surface damage and internal degradation of blanks under increasingly hostile conditions. The combination of service conditions and manufacturing process including chemical etching and polishing can inevitably modify the surface of quartz crystal blanks with changes of material properties, raising the question of what will happen to vibrations of quartz crystal resonators of thickness-shear type if such modifications to blanks are to be evaluated for sensitive applications. Such questions have been encountered in other materials and structures with property variations either on purpose or as the effect of environmental or natural processes commonly referred to as functionally graded materials, or FGMs. Analyses have been done in applications as part of studies on FGMs in structural as well as in acoustic wave device applications. A procedure based on series solutions has been developed in the evaluation of frequency changes and features in an infinite quartz crystal plate of AT-cut with the symmetric material variation pattern given in a cosine function with the findings that the vibration modes are now closely coupled. These results can be used in the evaluation of surface damage and corrosion of quartz crystal blanks of resonators in sensor applications or development of new structures of resonators.

description: This paper identifies and investigates nature of the transition between Gaussian and exponential forms of decoherence. We show that the decoherence factor (that controls the time dependence of the suppression of the off-diagonal terms when the density matrix is expressed in the pointer basis representation) can be described by the convolution of Gaussian and exponential functions, their contributions modulated by the strength of the system-environment interaction. In the strong and weak coupling limits, decoherence reduces to the familiar Gaussian and exponential forms, respectively. The mechanism is demonstrated with two paradigmatic examples of decoherence -- a spin-bath model and the quantum Brownian motion.

description: A double-edged sword in two-dimensional material science and technology is an optically forbidden dark exciton. On the one hand, it is fascinating for condensed matter physics, quantum information processing, and optoelectronics due to its long lifetime. On the other hand, it is notorious for being optically inaccessible from both excitation and detection standpoints. Here, we provide an efficient and low-loss solution to the dilemma by reintroducing photonics bound states in the continuum (BICs) to manipulate dark excitons in the momentum space. In a monolayer tungsten diselenide under normal incidence, we observed a giant enhancement with an enhancement factor of ~3,100 for dark excitons enabled by transverse magnetic BICs with intrinsic out-of-plane electric fields. By further employing widely tunable Friedrich-Wintgen BICs, we demonstrated highly directional emission from the dark excitons with a divergence angle of merely 7 degrees. We found that the directional emission is coherent at room temperature, unambiguously shown in polarization analyses and interference measurements. Therefore, the BICs reintroduced as a momentum-space photonic environment could be an intriguing platform to reshape and redefine light-matter interactions in nearby quantum materials, such as low-dimensional materials, otherwise challenging or even impossible to achieve.

Актуализирован вопрос о необходимости развития действующих экономических механизмов охраны окружающей среды, которые, как показывает практика, мало эффективны. Проведен анализ практики экономического стимулирования субъектов хозяйственной деятельности по снижению техногенной нагрузки на окружающую природную среду в Российской Федерации. Обосновано, что одним из эффективных путей стимулирования является такой экономический инструмент как плата за негативное влияние на окружающую среду. Исследованы преимущества и недостатки практики предложенного вида стимулирования. Обозначены пути совершенствования данной практики с учетом адекватной оценки негативного влияния загрязняющих веществ на окружающую среду. Предложена усовершенствованная методика расчета платежей за загрязнения с ориентацией на реальные величины ущерба, которая позволит с наибольшей точностью оценить фактически нанесенный вред субъектом хозяйствования окружающей среде. В качестве перспектив дальнейших исследований предлагается апробация предложенной методики на предприятиях г. Севастополя.

description: The desire to attain long-term sustainability of water supply services calls for a better understanding of the relationship between improved operations and maintenance practices, and the effectiveness and sustainability of water supply services. Policies and strategy frameworks play a critical role in ensuring the long-term sustainability of water supply and management services. Indeed, to achieve the targets of the SDGs, more focus on the longer-term sustainable management of water service provision is recommended, which demands a shift towards enhanced water sector governance, strong political will, an enhanced enabling environment, and stronger institutions, among other shifts (World Bank, 2017). This research study, the Itang case study in Gambella, Ethiopia, therefore looks at what facilitative policies and frameworks are in place to support improved service delivery and ensure the sustainability of the Itang water supply system. In order to consider the various arguments about sustainable water supply delivery services, a review of the Itang water utility governance structure and the level of service provision was undertaken as part of this research. The study also reviewed the level of implementation of the various policies, strategies and frameworks for the Itang water supply model and identified further framework and policy areas that are required to improve the sustainability of the water supply systems and services. The information obtained from this study will help the actors of Itang and Gambella water sector to align the operation and maintenance (O&M) policies and frameworks and help prioritize improvements towards sustainable and reliable water service provision. Indeed, this report will therefore contribute significantly to the knowledge base on policies and strategy frameworks, not only supporting the sustainability of the Itang town water and sewerage utility service delivery model in Gambella, Ethiopia, but also similar integrated water service management models globally.

description: На территории РФ хозяйствующие субъекты по-разному относятся к вопросам накопления, хранения и утилизации, образующихся отходов. Для крупных промышленных предприятий данная проблема более прозрачна и отлажена, а вот для малых форм и частных предпринимателей это достаточно серьезная проблема. Исследования проведены на территории Упоровского района Тюменской области. Объектом исследований было выбрано предприятие ИП «Швиндт А.А.». В статье проанализирована деятельность предприятия малой формы собственности по обращению с отходами производства и потребления. Данные по накоплению, хранению и утилизации отходов на предприятии проанализированы в течение 1 года. Всего за период с августа 2017 г. по июль 2018 г. на предприятии образовалось 75021 кг отходов 4 и 5 классов опасности. В структуре предприятия выделяют 5 подразделений: магазины в с. Емуртла (2), с. Морево. д. Короткова и пекарня в с. Емуртла. В статье представлены данные по зависимости количества образовавшихся отходов от времени года и от вида производственной деятельности. На территории каждого объекта оборудована специальная площадка для хранения ТКО, а также специальная емкость для хранения пищевых и органических остатков. Накопление, хранение и утилизация отходов на предприятии происходит в соответствии с требованиями законодательства РФ на специально оборудованных площадках.

description: We consider the minimisation of power-law repulsive-attractive interaction energies which occur in many biological and physical situations. We show existence of global minimizers in the discrete setting and get bounds for their supports independently of the number of Dirac Deltas in certain range of exponents. These global discrete minimizers correspond to the stable spatial profiles of flock patterns in swarming models. Global minimizers of the continuum problem are obtained by compactness. We also illustrate our results through numerical simulations.

title: The impact of political institutions on the risk of foreign banks in Europe
Creators: name: Li, Hongyu
Publisher: name: University of Glasgow

description: This thesis uses data on 899 commercial banks and macroeconomic variables for a total of 28 countries in the EU for the period 2000-2017, prior to Brexit, in order to avoid Covid-19 effects on trade that would bias the results in this thesis. The Z-score is used as the main indicator of bank risk-taking, and Henisz's (2000) political constraint index is used as the main proxy for political institutions to examine how political institutions affect foreign bank risk-taking. In the literature review section, this thesis collates the current state of research and relevant literature in the field of finance in relation to political institutions, commercial banking risks and on EU finance. A brief analysis of the various areas that may be covered by finance in the future is provided. In addition to this, compared to previous studies, this thesis includes a correlation coefficient matrix, a multiple co-integration test, and the reasons for choosing a fixed effects model to further ensure the robustness of the thesis's findings. The main conclusion drawn from the study is that bank risk-taking is significantly higher in countries with well established political systems.

description: В статье исследован мировой опыт проектирования жилых зданий с применением технологий «зеленого» строительства. Сегодня имеет место рост негативных антропогенных воздействий на природу, что ставить перед мировой общественностью вопрос о том, каким образом необходимо решать проблемы, возникающие при взаимодействии природы и человека. Среди таких проблем особое место отводится программе энергосбережения и её цифровой безопасности [10-11]. Указанная проблема является новой, её поднимали специалисты ещё в конце XX века. В качестве актуальной также следует назвать проблему экологического кризиса. Значительно ухудшает экологическое состояние, наряду с другими факторами, и архитектура. К процессам возведения и эксплуатации зданий становится источником выбросов в окружающую среду значительного количества вредных веществ. Процесс воздействия человека на природу является неизбежным, однако к задаче прогрессивного человечества является сокращение такого воздействия путем проектирование энергоэффективных жилых домов. В странах Европы, США, Канады проводятся интенсивные разработки в этой сфере. Автор приходит к выводу, чтов России реализация архитектуры энергоэффективных зданий требует создания методологии их проектирования.За счет повышения энергоэффективности жители домов снижают свою зависимость от энергои теплоцентралей,поскольку за счет энергосберегающих систем обеспечивается автономность жилой застройки С учетом указанных технологий, становится возможным освоение для строительства домов ранее не задействованных по причине своей непригодности территорий, так как обеспечение таких зданий энергоресурсами производится автономно. Важной является такжеэкологичность строительства указанных выше домов, за счет чего возрастает качество жизненной среды и устойчивость среды обитания.

description: La criminalité financière, qui se manifeste notamment par le blanchiment des capitaux et le financement du terrorisme, est un sujet d'actualité qui interpelle tous les acteurs de l'activité économique et sociale : économistes, juristes et banquiers. Ces derniers doivent inscrire leur action dans le cadre réglementaire de la prévention et la lutte contre la criminalité financière. Cela conduit alors à s'interroger sur les pratiques de la gestion des risques dans l'application des dispositifs en la matière. La gestion des risques au sein d'une banque est le processus qui permet d'identifier et d'évaluer les risques afin d'élaborer des plans d'action visant à minimiser les risques et à maîtriser les impacts éventuels sur la banque. A cet effet, nous allons-nous intéresser à la problématique suivante : « Dans quelle mesure, la gestion des risques contribue-t-elle à la prévention et à la lutte contre la criminalité financière au sein du secteur bancaire ? ». Dans cette perspective, cet article examine le concept de risque, le concept de gestion des risques en général, et ensuite la gestion des risques dans la prévention et la lutte contre la délinquance financière dans le secteur bancaire, et ce à partir d'une revue de la littérature. Et, analyse le rôle de la gestion des risques dans la prévention et la lutte contre la criminalité financière dans le secteur bancaire à travers une enquête réalisée auprès d'un échantillon de professionnels de la banque.

The Effect of Conjunctions on the Transit Timing Variations of Exoplanets

description: We develop an analytic model for transit timing variations produced by orbital conjunctions between gravitationally interacting planets. If the planetary orbits have tight orbital spacing, which is a common case among the Kepler planets, the effect of a single conjunction can be best described as: (1) a step-like change of the transit timing ephemeris with subsequent transits of the inner planet being delayed and those of the outer planet being sped up, and (2) a discrete change in sampling of the underlying oscillations from eccentricity-related interaction terms. In the limit of small orbital eccentricities, our analytic model gives explicit equations for these effects as a function of the mass and orbital separation of planets. We point out that a detection of the conjunction effect in real data is of crucial importance for the physical characterization of planetary systems from transit timing variations.

description: Topology identification comprises reconstructing the interaction Hamiltonian of a quantum network by properly processing measurements of its density operator within a fixed time interval. It finds application in several quantum technology contexts, ranging from quantum communication to quantum computing or sensing. In this paper, we provide analytical conditions for the solvability of the topology identification problem for autonomous quantum dynamical networks. The solvability condition is then converted in an algorithm for quantum network reconstruction that is easily implementable on standard computer facilities. The obtained algorithm is tested for Hamiltonian reconstruction on numerical examples based on the quantum walks formalism.
