description: Η παρούσα διπλωματική εργασία εξετάζει την ελαστική ευστάθεια μεταλλικών προεντεταμένων δοκών. Ειδικότερα αναλύεται η εύρεση του κρίσιμου φορτίου λυγισμού για διατομές με ροπή αδρανείας επί του ισχυρού άξονα σημαντικά μεγαλύτερη από του ασθενούς. Για αυτές τις διατομές η κύρια μορφή λυγισμού είναι η στρέβλωση. Κατά την ανάλυση υπολογίζεται το παραγόμενο έργο λόγω παραμορφώσεων και εξωτερικών δυνάμεων μέσω της μεθόδου του δυναμικού, καθορίζονται οι διαφορικές εξισώσεις του προβλήματος μέσω του λογισμού των διαφορών και παράγονται αριθμητικά αποτελέσματα για δύο χαρακτηριστικές διατομές μεταβαλλόμενου μήκους. Παρατίθενται συμπεράσματα που αφορούν στην αποτίμηση των αριθμητικών αποτελεσμάτων.
description: In the present graduation thesis the elastic stability of prestressed steel beams is examined. More precise the calculation of the critical buckling load is presented for section where the main moment of inertia is significantly greater than this of the secondary one. For these sections the main buckling form is warping. During the analysis the produced work due to deformation and external forces is calculated through the principle of conservation of energy, the differential equations of the problem are defined through the method of differences and numerical results are produced for two individual sections. The results displayed are in consideration to the numerical results produced by the analysis.

 Distribution. – Dry Zone of Sri Lanka.
 Diagnosis. – Colour and pattern much as in M. indica, but upper row of spots does notextensively fuse into acontinuous stripe on the shoulder. Size small, hindlegs relatively long (this is not an artifact of differing measurement styles; it can be verified bylaying the hindlegs. Measurements mostly intermediate between the other two species; in that the observed ranges are completely separate (and the means are at least 1 s.d. apart, usually 2 s.d.), the following are diagnostic cf. M. indica (in mm): zygomaticbreadth <50, occipital height (from basion) <27.5, width across canine alveoli <15, braincase breadth <33; and the following is diagnostic cf. M. kathygre new species: hindfoot>120.

Aho-Corasick Trees for Efficient Data Storage and Machine Learning

Publisher: name: Zenodo
Year: 2024

description: In this work we present to reader the novel research on account for efficiency of compressionalgorithms like Lempel-Ziv Welch and Aho-Corasick trees. We use them to build the proper storage which iscalled file system in a separate or generalized stream of data. These streams weren’t adopted before for bigdata to be compressed and queried at a fast pace. We will show further that this is the most efficient modelfor storing arrays of data on a server end for a final file system. The efficient algorithm for MachineLearning on Aho-Corasick trees is also presented which performs the query in linear time without gettingmore time on the models like neural networks which are very hardware demanding nowadays. The datastructure like trie by Turing Award winner Alfred V. Aho and Margaret J. Corasick remain of big potentialin the present time and are subjected to extensive research in this work.
Nonsteady-state diffusion in two-dimensional periodic channels

description: The dynamics of a freely diffusing particle in a two-dimensional channel with cross sectional area $A(x)$, can be effectively described by a one-dimensional diffusion equation under the action of a potential of mean force $U(x)=-k_BT\ln [A(x)]$ (where $k_BT$ is the thermal energy) in a system with a spatially-dependent diffusion coefficient $D(x)$. Several attempts to derive expressions relating $D(x)$ to $A(x)$ and its derivatives have been made, which were based on considering stationary flows in periodic channels. Here, we take an alternative approach and consider non-steady state single particle diffusion in an open periodic channel. The approach allows us to express $D(x)$ as a series of terms of increasing powers of $ε$ - a parameter associated with the aspect ratio of the channel. When the expansion is truncated at the leading term, we recover the expression suggested by Zwanzig [J. Phys. Chem. {\bf 96}, 3926 (1992)] for $D(x)$. Furthermore, comparison of the first few terms in our expansion for $D(x)$ with the one proposed by Kalinay and Percus [Phys. Rev. E {\bf 74}, 041203 (2006)] shows that they are consistent with each other. In the limit of long wavelength channels ($ε\ll 1$), the expansion converges rapidly and the leading approximation provides a very accurate description of the two-dimensional dynamics. For short wavelength channels, the expansion does not converge and the validity of the effective one-dimensional description is questionable.

Gap ratio in anharmonic charge-density-wave systems

description: Many experimental systems exist that possess charge-density-wave order in their ground state. While this order should be able to be described with models similar to those used for superconductivity, nearly all systems have a ratio of the charge-density-wave order parameter to the transition temperature that is too high for conventional theories. Recent work explained how this can happen in harmonic systems, but when the lattice distortion gets large, anharmonic effects must play an increasingly important role. Here we study the gap ratio for anharmonic charge-density wave systems to see whether the low-temperature properties possess universality as was seen previously in the transition temperature and to see whether the explanation for the large gap ratios survives for anharmonic systems as well.

Short range order in a steady state of irradiated Cu-Pd alloys: Comparison with fluctuations at thermal equilibrium

description: The equilibrium short-range order (SRO) in Cu-Pd alloys is studied theoretically. The evolution of the Fermi surface-related splitting of the (110) diffuse intensity peak with changing temperature is examined. The results are compared with experimental observations for electron-irradiated samples in a steady state, for which the temperature dependence of the splitting was previously found in the composition range from 20 to 28 at.% Pd. The equilibrium state is studied by analysing available experimental and theoretical results and using a recently proposed alpha-expansion theory of SRO which is able to describe the temperature-dependent splitting. It is found that the electronic-structure calculations in the framework of the Korringa-Kohn-Rostoker coherent potential approximation overestimate the experimental peak splitting. This discrepancy is attributed to the shift of the intensity peaks with respect to the positions of the corresponding reciprocal-space minima of the effective interatomic interaction towards the (110) and equivalent positions. Combined with an assumption about monotonicity of the temperature behaviour of the splitting, such shift implies an increase of the splitting with increasing temperature for all compositions considered in this study. The alpha-expansion calculations seem to confirm this conclusion.

The goal is to describe the magnetic properties of the compound (NBu_{4})_{2}Mn_{2}[Cu(opba)]_{3}\cdot 6DMSO\cdot H_{2}O which exhibits a ferromagnetic transition at $T_{c}=15K$. Extrapolating our analysis on the basis of renormalisation group arguments, we find that this transition may result from a very weak anisotropy effect.

Local gauge invariance and formation of topological defects

Publisher: name: arXiv
Year: 2001
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: In superconductors, and in other systems with a local U(1) gauge invariance, there are two mechanisms that form topological defects in phase transitions. In addition to the standard Kibble mechanism, thermal fluctuations of the magnetic field also lead to defect formation. This mechanism is specific to local gauge theories, predicts a qualitatively different spatial defect distribution and is the dominant source for topological defects in slow transitions. I review the arguments that lead to these conclusions and discuss possibilities of testing the scenario in superconductor experiments.

The weak decay form factors are calculated with the comprehensive account of all relativistic effects without employing nonrelativistic and heavy quark expansions. On this basis differential and total decay rates as well as different asymmetry parameters are calculated for the heavy-to-heavy $Ξ_b\to Ξ_c\ellν_\ell$ and heavy-to-light $Ξ_b\to Λ\ellν_\ell$ semileptonic decays. Predictions for the ratios of such decays involving $τ$ lepton and muon are presented.

An alternative approach is developed which maps the initial magneto-elastic problem to an effective magnetic problem only. Thus the equivalence of magneto-elastic solitons and magnetic spinons is shown. No soft phonon is required for the transition.

We use the coupled-cluster method (CCM) to calculate the ground-state energy, the T=0 sublattice magnetisation and the excited state energies, all as functions of the anisotropy parameter $γ$. We consider $S=1/2$ in detail and give some results for higher $S$. In 1D these results are compared with the exact $S=1/2$ results and in 2D with Monte-Carlo and series expansions. We obtain critical points close to the expected value $γ=0$ and our extrapolated LSUBn results for the ground-state energy are well converged for all $γ$ except very close to the critical point.

description: We study whether specific combinations of technological advancements can signal the presence of local capabilities allowing for a given industrial production. To this end, we generate a multi-layer network using country-level patent and trade data, and perform a motif-based analysis on this network using a statistical validation approach derived from maximum entropy arguments. We show that in many cases the signal far exceeds the noise, providing robust evidence of synergies between different technologies that can lead to a competitive advantage in specific markets. Our results can be highly useful for policy makers to inform industrial and innovation policies.

Scalability Evaluation of Iterative Algorithms Used for Supercomputer Simulation of Physical processes

Publisher: name: arXiv

Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)
subject: FOS: Computer and information sciences

description: The paper is devoted to the development of a methodology for evaluating the scalability of compute-intensive iterative algorithms used in simulating complex physical processes on supercomputer systems. The proposed methodology is based on the BSF (Bulk Synchronous Farm) parallel computation model, which makes it possible to predict the upper scalability bound of an iterative algorithm in early phases of its design. The BSF model assumes the representation of the algorithm in the form of operations on lists using high-order functions. Two classes of representations are considered: BSF-M (Map BSF) and BSF-MR (Map-Reduce BSF). The proposed methodology is described by the example of the solution of the system of linear equations by the Jacobi method. For the Jacobi method, two iterative algorithms are constructed: Jacobi-M based on the BSF-M representation and Jacobi-MR based on the BSF-MR representation. Analytical estimations of the speedup, parallel efficiency and upper scalability bound are constructed for these algorithms using the BSF cost metrics on multiprocessor computing systems with distributed memory. An information about the implementation of these algorithms in C++ language using the BSF program skeleton and MPI parallel programming library are given. The results of large-scale computational experiments performed on a cluster computing system are demonstrated. Based on the experimental results, an analysis of the adequacy of estimations obtained analytically by using the cost metrics of the BSF model is made.

On Series Expansions of Capparelli's Infinite Product
Creators: name: Sills, Andrew V.
Publisher: name: arXiv
Year: 2018
Subjects: subject: Classical Analysis and ODEs (math.CA)
subject: FOS: Mathematics

description: Using Lie theory, Stefano Capparelli conjectured an interesting Rogers-Ramanujan type partition identity in his 1988 Rutgers Ph.D. thesis. The first proof was given by George Andrews, using combinatorial methods. Later, Capparelli was able to provide a Lie theoretic proof. Most combinatorial Rogers-Ramanujan type identities (e.g. the Göllnitz-Gordon identities, Gordon's combinatorial generalization of the Rogers-Ramanujan identities, etc.) have an analytic counterpart. The main purpose of this paper is to provide two new series representations for the infinite product associated with Capparelli's conjecture. Some additional related identities, including new infinite families are also presented.

description: This work presents a novel diagnostic tool for studying the thermodynamics of the climate systems with a wide range of applications, from sensitivity studies to model tuning. It includes a number of modules for assessing the internal energy budget, the hydrological cycle, the Lorenz Energy Cycle and the material entropy production, respectively. The routine receives as inputs energy fluxes at surface and at the Top-of-Atmosphere (TOA), for the computation of energy budgets at Top-of-Atmosphere (TOA), at the surface, and in the atmosphere as a residual. Meridional enthalpy transports are also computed from the divergence of the zonal mean energy budget fluxes; location and intensity of peaks in the two hemispheres are then provided as outputs. Rainfall, snowfall and latent heat fluxes are received as inputs for computing the water mass and latent energy budgets. If a land-sea mask is provided, the required quantities are separately computed over continents and oceans. The diagnostic tool also computes the Lorenz Energy Cycle (LEC) and its storage/conversion terms as annual mean global and hemispheric values. In order to achieve this, one needs to provide as input three-dimensional daily fields of horizontal wind velocity and temperature in the troposphere. Two methods have been implemented for the computation of the material entropy production, one relying on the convergence of radiative heat fluxes in the atmosphere (indirect method), one combining the irreversible processes occurring in the climate system, particularly heat fluxes in the boundary layer, the hydrological cycle and the kinetic energy dissipation as retrieved from the residuals of the LEC. A version of the diagnostic tool is included in the Earth System Model eValuation Tool (ESMValTool) community diagnostics, in order to assess the performances of soon available CMIP6 model simulations.

cab light

description: The cab signaling is inevitable for fast trains. And search towards cab signaling is about for more than a century. This chapter is about wireless cab signaling which is economic and reliable. The current method of signalling in Indian railways is through traditional land post light signals controlled from the station, and the light signals regulate train operation. It is often difficult to drive the train at a steady pace due to poor visibility caused by climatic conditions [mist and heavy rain], fast blind turns, up and downs, and blinding sunshine, and it is necessary to apply brakes, which causes pain and wastes energy and time. We can provide cab signals to the loco pilot instantly to improve the output of the train service without any interruption due to the above cause. With the aid of traditional land post light signal control, I present a method for providing cab light signal by electromagnetic waves (EMW). To improve the efficiency of the Indian railway signalling system, the proposed system is a preliminary implementation of cab signalling that is linked and combined with the existing automatic block signalling system.

description: Ramsey's theorem asserts that every $k$-coloring of $[ω]^n$ admits an infinite monochromatic set. Whenever $n \geq 3$, there exists a computable $k$-coloring of $[ω]^n$ whose solutions compute the halting set. On the other hand, for every computable $k$-coloring of $[ω]^2$ and every non-computable set $C$, there is an infinite monochromatic set $H$ such that $C \not \leq_T H$. The latter property is known as cone avoidance. In this article, we design a natural class of Ramsey-like theorems encompassing many statements studied in reverse mathematics. We prove that this class admits a maximal statement satisfying cone avoidance and use it as a criterion to re-obtain many existing proofs of cone avoidance. This maximal statement asserts the existence, for every $k$-coloring of $[ω]^n$, of an infinite subdomain $H \subseteq ω$ over which the coloring depends only on the sparsity of its elements. This confirms the intuition that Ramsey-like theorems compute Turing degrees only through the sparsity of its solutions.

description: The duration of quasar accretion episodes is a key quantity for distinguishing between models for the formation and growth of supermassive black holes, the evolution of quasars, and their potential feedback effects on their host galaxies. However, this critical timescale, often referred to as the quasar lifetime, is still uncertain by orders of magnitude ($t_{\rm Q} \simeq 0.01\,{\rm Myr} - 1\,{\rm Gyr}$). Absorption spectra of quasars exhibiting transmission in the He II Ly$α$ forest provide a unique opportunity to make precise measurements of the quasar lifetime. Indeed, the size of a quasar's He II proximity zone, the region near the quasar itself where its own radiation dramatically alters the ionization state of the surrounding intergalactic medium (IGM), depends sensitively on its lifetime for $t_{\rm Q}\lesssim 30$ Myr, comparable to the expected $e$-folding time-scale for SMBH growth $t_{\rm S}=45$ Myr. In this study we compare the sizes of He II proximity zones in the Hubble Space Telescope (HST) spectra of 6 z~4 quasars to theoretical models generated by post-processing cosmological hydrodynamical simulations with $1$D radiative transfer algorithm. We introduce a Bayesian statistical method to infer the lifetimes of individual quasars which allows us to fully marginalize over the unknown ionization state of the surrounding IGM. We measure lifetimes $0.63^{+0.82}_{-0.40}$ Myr and $5.75^{+4.72}_{-2.74}$ Myr for two objects. For the other 4 quasars large redshift uncertainties undermine our sensitivity allowing us to only place upper or lower limits. However a joint analysis of these four systems yields a measurement of their average lifetime of $\langle t_{\rm Q}\rangle = 1.17^{+1.77}_{-0.84}$ Myr. We discuss our short ~1 Myr inferred lifetimes in the context of other quasar lifetime constraints and the growth of SMBHs.

description: Faro de Limanes, Principado de Asturias, Spain is one of the most important pottery centers in the northwest of the Iberian Peninsula for medieval and modern times, with activity from the 11th century to the present. In medieval times, only black wares were produced, which responded, above all, to forms related to the preparation and storage of food. In modern times, tin-lead glazed, white lead glazed wares and honey-glazed wares productions are added, dedicated to food consumption. His pieces appear in large quantities and in a multitude of archaeological contexts, reaching a notable dispersion.

Our work investigates how ceramic production from medieval and modern times has conditioned contemporary production. The archaeological investigations and excavations in the center have influenced contemporary production and have conditioned the work of the potters. The pieces are reinvented following old patterns and not based on the new needs of the population. The study of medieval and modern pieces allows us to compare the data with contemporary production and understand the evolution of pottery. It is evident how medieval and modern archeology has been the engine of change in a ceramic production with more than a thousand years of history.

description: We study the entanglement-breaking (EB) space, such that the entanglement of formation (EOF) of a bipartite quantum state is additive when its range is an EB subspace. We systematically construct the EB spaces in the Hilbert space $\bbC^m\otimes\bbC^3$, and the $2$-dimensional EB space in $\bbC^2\otimes\bbC^n$. We characterize the expression of two-qubit states of rank two with nonadditive EOF, if they exist. We further apply our results to construct EB spaces of an arbitrarily given dimensions. We show that the example in [PRL 89,027901(2002)] is a special case of our results. We further work out the entanglement cost of a qubit-qutrit state in terms of the two-atom system of the .

description: A obra de Fernando Pessoa, atribuída a diversos heterónimos e deixada maioritariamente inédita à hora da sua morte, levanta frequentes questões de autoria. O termo “autor” é raramente utilizado de forma explícita por Pessoa, que prefere referir-se ao herói ou ao génio. Defenderei, neste artigo, que Pessoa concebe o Livro do Desassossego como teoria e prova daquilo que poderia ter definido como autor exemplar. Considerarei, com esse intuito, os aspectos que me parecem justificar a singularidade deste livro.

description: Digital technologies, from smartphones to the Internet of Things, have significantly changed lives, organisations, and societies. The UK, a leader in developing future technologies like artificial intelligence, aims to boost its technology ecosystem, which is central to its economic growth as highlighted in the HM Treasury Autumn Statement 2023.The UK's digital sector, with a gross value added growth of 19% since February 2020, outpaces the overall UK economy's 2.3% growth. By 2022, the sector contributed approximately £158 billion, accounting for 7% of the UK's gross value added as of September 2023. Digital technology has also notably impacted the charity sector, enhancing fundraising, marketing, service delivery, and operations, especially accelerated by COVID-19. Yet, over half of UK charities are still in the early stages of digital adoption, and 73% feel unprepared for AI, despite recognising its potential.This study explores the opportunities and challenges of digital adoption in the UK charity sector, aiming to understand the facilitators and barriers and offer recommendations for its future digital development.

description: We consider the Cauchy problem for semilinear parabolic equation in divergence form with obstacle. We show that under natural conditions on the right-hand side of the equation and mild conditions on the obstacle the problem has a unique solution and we provide its stochastic representation in terms of reflected backward stochastic differential equations. We prove also regularity properties and approximation results for solutions of the problem.

description: Ο σκοπός αυτής της διπλωματικής εργασίας ήταν η μελέτη των αντιδράσεων της τοπικής κοινωνίας (ΝΙΜΒΥ) σε διάφορα έργα ή δραστηριότητες, καθώς και ο τρόπος διαχείρισης των αντιδράσεων αυτών. Αρχικά έγινε μια εκτενής ανάλυση του φαινομένου ΝΙΜΒΥ, η οποία περιλαμβάνει την ερμηνεία του όρου, την ιστορική εξέλιξή του, τα αίτια που το δημιουργούν, τα χαρακτηριστικά των ατόμων που υιοθετούν αυτή τη στάση και τους τρόπους αντιμετώπισης του συνδρόμου, συνοδευόμενη από παραδείγματα αποδοχής ή απόρριψης έργων από την τοπική κοινωνία. Ακολούθως, επιλέχθηκε να μελετηθεί η περίπτωση των αντιδράσεων απέναντι στα αιολικά πάρκα και συγκεκριμένα στην πρόταση που έχει υποβάλλει γνωστή εταιρία για την κατασκευή θαλάσσιου αιολικού πάρκου στον όρμο των Πεταλιών, με τη διεξαγωγή απευθείας συνεντεύξεων. Σκοπός ήταν να αποτυπωθεί η άποψη της τοπικής κοινωνίας σε σχέση με το συγκεκριμένο έργο. Τέλος, με τη χρήση στατιστικού προγράμματος, αναλύθηκαν τα αποτελέσματα της κοινωνικής έρευνας και έγινε η οικονομική αποτίμηση της απομάκρυνσης του έργου από την περιοχή και της κατασκευής του σε κάποιον άλλο δήμο του Νομού Αττικής.
description: The aim of this postgraduate thesis was the examination of reactions of local society (NIMBY) in various work or activities, as well as the way of managing these reactions. Initially an extensive analysis of NIMBY phenomenon was made, which includes the interpretation of the term, its historical development, the reasons that create it, the characteristics of individuals that adopt this attitude and the ways of confrontation of this syndrome, accompanied with examples of acceptance or reject of a project from local society. Furthermore, it was selected to be studied the case of reactions toward the wind parks and specifically the proposal that well-known company has submitted for the manufacture of an offshore wind park in the gulf of Petalion, with the conduct of direct interviews. The aim was to write down the opinion of local society in regard to this particular project. Finally, by using a statistical program, the results of the social research were analyzed and an economic assessment was made for the removal of this project from the region and for manufacturing it in some other municipality of the Prefecture Attica.

description: We discuss the possible extensions of Bethe/gauge correspondence to quantum integrable systems based on the super-Lie algebras of A type. Along the way we propose the analogues of Nakajima quiver varieties whose cohomology and K-theory should carry the representations of the corresponding Yangian and the quantum affine algebras, respectively. We end up with comments on the N=4 planar super-Yang-Mills theory in four dimensions.
