Process mining
Event log files

description: Η εξόρυξη διαδικασιών (process mining), είναι ένας σχετικά νέος ερευνητικός τομέας που περιλαμβάνει την ανακάλυψη, εποπτεία και στον εμπλουτισμό των διαδικασιών μέσω της εξαγωγής γνώσης από το ιστορικό των γεγονότων (event logs), το οποίο υπάρχει συνήθως διαθέσιμο στα Πληροφοριακά Συστήματα. Τα περισσότερα Πληροφοριακά Συστήματα όμως δεν παράγουν event log αρχεία, κατάλληλα για ανάλυση μέσω της εξόρυξης των διαδικασιών. Ωστόσο, είναι δυνατή η κατασκευή ενός event log αρχείου με την εξαγωγή της κατάλληλης πληροφορίας από μία βάση δεδομένων με τη βοήθεια του εργαλείου XESame. Στη παρούσα εργασία έγινε προσπάθεια εύρεσης διαδικασιών από αρχεία που δόθηκαν από την Περιφέρεια Κεντρικής Μακεδονίας και είναι βάσεις που αφορούν στο Πρωτόκολλο Εμπορικών και Βιομηχανικών εταιρειών για τις χρονιές 2002-2003. Αρχικά έγινε μετατροπή των βάσεων με το εργαλείο XESame σε μορφή κατάλληλη για επεξεργασία και στη συνέχεια χρησιμοποιήθηκε το εργαλείο ProM για την εξόρυξη των διαδικασιών. Η διαδικασία που εξήχθηκε αφορά στην ανάκληση άδειας λειτουργίας, παράλληλα, εξήχθηκε και ένα κοινωνικό δίκτυο που μας δείχνει τις ομάδες ατόμων που συνεργάζονται.
description: Process mining is a relatively new research area which include discover, monitor and enrichment of real processes by extracting knowledge from event logs commonly available in today's information systems. Most of the common Information Systems produce event log files suitable for process mining. It is possible to produce an event log file by extracting information from databases with the XESame tool. In this paper we attempted to find processes from databases of Region of Central Macedonia. Firstly databases were converted with XESame tool in a format suitable for editing and then the ProM tool has been used for process mining. The process which was derived was “the withdrawal of authorization”, also a social network that shows the groups of people working together, was exported.

description: Using neutron stars (NS) as a dark matter (DM) probe has gained broad attention recently, either from heating due to DM annihilation or its stability under the presence of DM. In this work, we investigate spin-$1/2$ fermionic DM $χ$ charged under the $U(1)_{X}$ in the dark sector. The massive gauge boson $V$ of $U(1)_{X}$ gauge group can be produced in NS via DM annihilation. The produced gauge boson can decay into Standard Model (SM) particles before it exits the NS, despite its tiny couplings to SM particles. Thus, we perform a systematic study on $χ\barχ\to2V\to4{\rm SM}$ as a new heating mechanism for NS in addition to $χ\barχ\to2{\rm SM}$ and kinetic heating from DM-baryon scattering. The self-trapping due to $χV$ scattering is also considered. We assume the general framework that both kinetic and mass mixing terms between $V$ and SM gauge bosons are present. This allows both vector and axial-vector couplings between $V$ and SM fermions even for $m_V\ll m_Z$. Notably, the contribution from axial-vector coupling is not negligible when particles scatter relativistically. We point out that the above approaches to DM-induced NS heating are not yet adopted in recent analyses. Detectabilities of the aforementioned effects to the NS surface temperature by the future telescopes are discussed as well.

description: We show that the cosmological constant at late time places a bound on the entropy of microwave background radiation deposited in the future event horizon of a given observer, $S\leq S_{Λ_0}^{3/4}$. This bound is independent of the energy scale of reheating and the FRW evolution after reheating. We also discuss why the entropy of microwave background in our observable universe has its present value.

description: Parton distributions can be defined in terms of the entropy of entanglement between the spatial region probed by deep inelastic scattering (DIS) and the rest of the proton. For very small $x$, the proton becomes a maximally entangled state. This approach leads to a simple relation $S = \ln N $ between the average number $N$ of color-singlet dipoles in the proton wave function and the entropy of the produced hadronic state $S$. At small $x$, the multiplicity of dipoles is given by the gluon structure function, $N = x G(x,Q^2)$. Recently, the H1 Collaboration analyzed the entropy of the produced hadronic state in DIS, and studied its relation to the gluon structure function; poor agreement with the predicted relation was found. In this letter we argue that a more accurate account of the number of color-singlet dipoles in the kinematics of H1 experiment (where hadrons are detected in the current fragmentation region) is given not by $xG(x,Q^2)$ but by the sea quark structure function $xΣ(x,Q^2)$. Sea quarks originate from the splitting of gluons, so at small $x$ $xΣ(x,Q^2)\,\sim\, xG(x,Q^2)$, but in the current fragmentation region this proportionality is distorted by the contribution of the quark-antiquark pair produced by the virtual photon splitting. In addition, the multiplicity of color-singlet dipoles in the current fragmentation region is quite small, and one needs to include $\sim 1/N$ corrections to $S= \ln N$ asymptotic formula. Taking both of these modifications into account, we find that the data from the H1 Collaboration in fact agree well with the prediction based on entanglement.

description: We resolve the local semistable reduction problem for overconvergent F-isocrystals at monomial valuations (Abhyankar valuations of height 1 and residue transcendence degree 0). We first introduce a higher-dimensional analogue of the generic radius of convergence for a p-adic differential module, which obeys a convexity property. We then combine this convexity property with a form of the p-adic local monodromy theorem for so-called fake annuli.

description: We report the results of a blind search for 22-GHz water masers in two regions, covering approximately half a square degree, within the giant molecular cloud associated with RCW 106. The complete search of the two regions was carried out with the 26-m Mount Pleasant radio telescope and resulted in the detection of nine water masers, five of which are new detections. Australia Telescope Compact Array (ATCA) observations of these detections have allowed us to obtain positions with arcsecond accuracy, allowing meaningful comparison with infrared and molecular data for the region. We find that for the regions surveyed there are more water masers than either 6.7-GHz methanol, or main-line OH masers. The water masers are concentrated towards the central axis of the star formation region, in contrast to the 6.7-GHz methanol masers which tend to be located near the periphery. The colours of the GLIMPSE point sources associated with the water masers are similar to those of 6.7-GHz methanol masers, but slightly less red. We have made a statistical investigation of the properties of the 13CO and 1.2-mm dust clumps with and without associated water masers. We find that the water masers are associated with the more massive, denser and brighter 13CO and 1.2-mm dust clumps. We present statistical models that are able to predict those 13CO and 1.2-mm dust clumps that are likely to have associated water masers, with a low misclassification rate.

description: We explicitly construct N=4 worldline supersymmetric minimal off-shell actions for five options of 1/2 partial spontaneous breaking of $N=8, d=1$ Poincaré supersymmetry. We demonstrate that the action for the N=4 Goldstone supermultiplet with four fermions and four auxiliary components is a universal one. The remaining actions for the Goldstone supermultiplets with physical bosons are obtained from the universal one by off-shell duality transformations.

description: В статье рассматривается авторская методика оценки эффективности отрасли мясного скотоводства с учетом имеющихся материальных и трудовых ресурсов и определенных организационно-технологических условий сельскохозяйственного предприятия, специализирующегося на производстве говядины. Коэффициент эффективности развития отрасли мясного скотоводства рассчитывается путем деления прибыли от реализации говядины на затраты, связанные с ее производством, а затем умножается на уровень обеспеченности бизнес-процесса мраморного мяса. Методика расчета показателя «уровень обеспеченности бизнес-процесса мраморного мяса» предусматривает бальную оценку факторов внутренней и внешней среды, оказывающих воздействие на производство говядины.The article deals with the author's method of assessing the effectiveness of the meat cattle industry, taking into account the available material and labor resources and certain organizational and technological conditions of the agricultural enterprise specializing in the production of beef. The coefficient of efficiency of development of the meat cattle industry is calculated by dividing the profit from the sale of beef by the costs associated with its production, and then multiplied by the level of security of the business process of marbled meat. The method of calculating the indicator "the level of security of the business process of marbled meat" provides a point assessment of the factors of internal and external environment affecting the production of beef.
Toward a unified framework of decision-making: the case of environmentally protective behaviour
Creators: name: Axelrod, Lawrence J.
Publisher: name: University of British Columbia
Year: 2009

description: Theoretical determinants of decisions regarding one’s behaviour are integrated into a comprehensive and inclusive framework. This framework is then employed to determine the factors responsible for guiding decisions regarding the protection of the natural environment. Included in the framework are constructs from four conceptual domains: (a) attitudinal phenomena, (b) efficacy beliefs, ( c) functional motivators of behaviour (i.e., outcome beliefs) and (d) personal values. In addition, the role of psychological motivators in the decision process is reviewed. Several advances in theory are suggested. First, attitudes towards objects (e.g., the natural environment) are differentiated from attitudes towards specific behaviours (e.g., recycling), and both concepts are incorporated into the framework. Second, it is recommended that different functional motives be defined and independently assessed. In the present research, three domains of outcomes (i.e., economic, social, and environmental) are specified and their motivational influence explored. Third, it is suggested that personal value orientations be included in a comprehensive study of behavioural decisions. A taxonomy of values specifying three domains (i.e., economic, social, and universal) is proposed and the influence of personal value orientations toward each domain on behavioural decisions is examined. Findings from three experiments suggest that constructs from all four conceptual domains are involved in guiding decisions to perform environmentally protective behaviours. Specifically, beliefs regarding behavioural outcomes and efficacy were the most directly associated with these behavioural decisions. More positive outcome expectations and stronger beliefs of self-efficacy and behavioural accessibility were associated with decisions to perform environmentally protective behaviours. Personal values also accounted for a significant amount of variance in behavioural decisions. In general, economically-oriented subjects were least likely to choose an environmentally protective course of action, whereas universally-oriented subjects were most likely to pursue environmental protection and preservation. As expected, a personal value x outcome belief interaction was found that showed that the decisions of economically-oriented subjects were consistently influenced by economic considerations, whereas the decisions of subjects in the other two value groups were not. Finally, attitudinal phenomena appear to be least important in guiding behavioural decisions. Theoretical considerations and implications regarding the promotion of environmentally protective behaviour are discussed.

description: Swarm intelligence systems typically consist of a population of single agents that interact locally with each other and with their environment. These agents follow very simple rules. Examples of swarm intelligence systems in nature include ant colonies, behaviors influx of birds, bacterial growth and education of fish. These properties, inspired by these natural systems, are used in the design of many algorithms. Ant colony optimization is a population based meta-heuristic method that can be used to find approximate solutions to difficult optimization problems. It is inspired by the foraging behavior of ants and their colonies and belongs to the family of swarm intelligence methods. In the present work the main principles of heuristic methods and Intelligence swarm are reported, while special attention is given to the ant colony optimization algorithm, which is described in detail. We present a literature review on the use of the algorithm in a variety of disciplines and finally a brief description of three software applications based on the above algorithm is made.

description: We derive a covariant expression for the renormalized holographic entanglement entropy for Conformal Field Theories (CFTs) dual to Quadratic Curvature Gravity in arbitrary dimensions. This expression is written as the sum of the bare entanglement entropy functional obtained using standard conical defect techniques, and a counterterm defined at the boundary of the extremal surface of the functional. The latter corresponds to the cod-2 self-replicating part of the extrinsic counterterms when evaluated on the replica orbifold. This renormalization method isolates the universal terms of the holographic entanglement entropy functional. We use it to compute the standard C-function candidate for CFTs of arbitrary dimension, and the type-B anomaly coefficient c for 4-dimensional CFTs.

Χρησιμοποιήθηκαν θεωρητικές δομές για ενώσεις με υποκαταστάτες δότες και δέκτες ηλεκτρονίων στο βόριο με σκοπό να μελετηθεί πώς επιδρά και επηρεάζει ο κάθε υποκαταστάτης το μαγνητικό πεδίο και να βγουν συμπεράσματα αν αυτές οι ενώσεις είναι αρωματικές, μη αρωματικές ή αντί-αρωματικές. Η θεωρητική τεχνική που χρησιμοποιήθηκε είναι η DFT/GIAO και τα κριτήρια για την αποτίμηση ήταν δυο: οι τιμές NICS-SCAN, ο διαχωρισμός και η συνεισφορά του κάθε ενός μοριακού τροχιακού στο επαγόμενο μαγνητικό πεδίο και οπτικοποίηση των αποτελεσμάτων. Συνολικά στόχος της εργασίας ήταν: 1. Να δωθεί μια εξήγηση της επίδρασης που έχει ο κάθε υποκαταστάτης στην συμπεριφορά της βοραζίνης ως προς την διατροπική ή παρατροπική συμπεριφορά της. 2. Να δωθεί μια ερμηνεία των NICS-SCAN και κατά πόσο μπορούν οι τιμές NICS να αποτελέσουν ένα πραγματικό κριτήριο αξιολόγησης της αρωματικότητας. 3.

description: The aim of the present thesis was the study of aromaticity with magnetic criteria in borazine. We have used theoretical structures with substituents electron donating and electron withdrawn groups in boron with purpose to explain how every substituent reacts on the magnetic field and to explain if those compounds can be considered as aromatic, anti-aromatic or non-aromatic. The theoretical technique is DFG/GIAO and the criteria of evaluation was: NICS-SCAN values, separation and contribution of each molecular orbital in induced magnetic field and visualization of the results. Generally we would like to: 1. Try to give an explanation of the effect of each substituent in the behavior of borazine to paratropic or diatropic character. 2.

description: We report the study of spontaneous magnetization (i.e., spin-polarization) for time-reversal symmetry (TRS)-breaking superconductors with unitary pairing potentials, in the absence of external magnetic fields or Zeeman fields. Spin-singlet ($Δ_s$) and spin-triplet ($Δ_t$) pairings can coexist in superconductors whose crystal structure lacks inversion symmetry. The TRS can be spontaneously broken once a relative phase of $\pmπ/2$ is developed, forming a TRS-breaking unitary pairing state ($Δ_s\pm iΔ_t$). We demonstrate that such unitary pairing could give rise to spontaneous spin-polarization with the help of spin-orbit coupling. Our result provides an alternative explanation to the TRS breaking, beyond the current understanding of such phenomena in the noncentrosymmetric superconductors. The experimental results of Zr$_3$Ir and CaPtAs are also discussed in the view of our theory.

description: A method is suggested allowing for the improvement of accuracy of self-similar factor and root approximants, constructed from asymptotic series. The method is based on performing a power transform of the given asymptotic series, with the power of this transformation being a control function. The latter is defined by a fixed-point condition, which improves the convergence of the sequence of the resulting approximants. The method makes it possible to extrapolate the behaviour of a function, given as an expansion over a small variable, to the region of the large values of this variable. Several examples illustrate the effectiveness of the method.

Δείγμα αποβλήτου από τον βιολογικό καθαρισμό Θεσσαλονίκης αναμίχθηκε με δείγμα αποβλήτου από μονάδα παραγωγής ζύμης αρτοποιίας και το μίγμα υπέστη κροκίδωση και οζονισμό σε διάφορες συνθήκες (δόση και είδος κροκιδωτικού, ρύθμιση pH, δόση όζοντος και χρόνος αντίδρασης). Η οξεία τοξικότητα των αρχικών αποβλήτων, των μιγμάτων τους αλλά και των επεξεργασμένων δειγμάτων αξιολογήθηκε με προσδιορισμό της αναστολής της φωταύγειας του βακτηρίου Vibrio fischeri. Επίσης προσδιορίστηκαν παράμετροι όπως οργανικό φορτίο, χρώμα, θολότητα, pH, αγωγιμότητα, ολικά στερεά και όγκος λάσπης. Κρίνεται αναγκαία η χρήση δοκιμών τοξικότητας σε συνδυασμό με τον προσδιορισμό φυσικοχημικών παραμέτρων για τον καλύτερο χαρακτηρισμό της ποιότητας των αποβλήτων και την εκτίμηση των αρνητικών επιπτώσεων στα οικοσυστήματα.
description: The aim of the present thesis was the study of the effect of coagulation and ozonation on the toxicity of molasses wastewater effluents. Samples collected from the effluent of the municipal wastewater treatment plant of Thessaloniki were mixed with molasses biologically treated effluents and were submitted to coagulation and ozonation under various conditions (coagulant dosage and type, pH, ozone reaction time and ozone dosage). The acute toxicity of the original, the mixed as well as the processed wastewater was evaluated by the bioluminescence inhibition of Vibrio fischeri. COD, color, turbidity, pH, conductivity, total solids and volume of sludge were parameters also evaluated. Toxicity bioassays should be used in conjunction to chemical analysis for the appropriate evaluation of the effluent properties and the assessment of their environmental impact.
Resource-conscious scheduling for energy efficiency on multicore processors

description: In multicore systems, shared resources such as caches or the memory subsystem can lead to contention between applications running on different cores, entailing reduced performance and poor energy efficiency. The characteristics of individual applications, the assignment of applications to machines and execution contexts, and the selection of processor frequencies have a dramatic impact on resource contention, performance, and energy efficiency. We employ the concept of task activity vectors for characterizing applications by resource utilization. Based on this characterization, we apply migration and co-scheduling policies that improve performance and energy efficiency by combining applications that use complementary resources, and use frequency scaling when scheduling cannot avoid contention owing to inauspicious workloads. We integrate the policies into an operating system scheduler and into a virtualization system, allowing placement decisions to be made both within and across physical nodes, and reducing contention both for individual tasks and complete applications. Our evaluation based on the Linux operating system kernel and the KVM virtualization environment shows that resource-conscious scheduling reduces the energy delay product considerably.

description: Having established the fact that interacting classical kicked rotor systems exhibit long-lived prethermal phase with quasi-conserved average Hamiltonian before entering into chaotic heating regime, we use spatio-temporal fluctuation correlation of kinetic energy to probe the above dynamic phases. We remarkably find the diffusive transport of fluctuation in the prethermal regime reminding us the underlying hydrodynamic picture in a generalized Gibbs ensemble with a definite temperature that depends on the driving parameter and initial conditions. On the other hand, the heating regime, characterized by a diffusive growth of kinetic energy, can sharply localize the correlation at the fluctuation center for all time. Consequently, we attribute non-diffusive and non-localize structure of correlation to the crossover regime, connecting the prethermal phase to the heating phase, where the kinetic energy displays complicated growth structure. We understand these numerical findings using the notion of relative phase matching where prethermal phase (heating regime) refers to an effectively coupled (isolated) nature of the rotors. We exploit the statistical uncorrelated nature of the angles of the rotors in the heating regime to find the analytical form of the correlator that mimics our numerical results in a convincing way.

description: We propose a quantum computation architecture of double-dot molecules, where the qubit is encoded in the molecule two-electron spin states. By arranging the two dots inside each molecule perpendicular to the qubit scaling line, the interactions between neighboring qubits are largely simplified and the scaling to multi-qubit system becomes straightforward. As an Ising-model effective interaction can be expediently switched on and off between any two neighboring molecules by adjusting the potential offset between the two dots, universal two-qubit gates can be implemented without requiring time-dependent control of the tunnel coupling between the dots. A Bell-state measurement scheme for qubit encoded in double-dot singlet and triplet states is also proposed for quantum molecules arranged in this way.

description: We address the occurrence of narrow planetary rings and some of their structural properties, in particular when the rings are shepherded. We consider the problem as Hamiltonian {\it scattering} of a large number of non-interacting massless point particles in an effective potential. Using the existence of stable motion in scattering regions in this set up, we describe a mechanism in phase space for the occurrence of narrow rings and some consequences in their structure. We illustrate our approach with three examples. We find eccentric narrow rings displaying sharp edges, variable width and the appearance of distinct ring components (strands) which are spatially organized and entangled (braids). We discuss the relevance of our approach for narrow planetary rings.

Local Perturbations Do Not Affect Stability of Laboratory Fruitfly Metapopulations

description: A large number of theoretical studies predict that the dynamics of spatially structured populations (metapopulations) can be altered by constant perturbations to local population size. However, these studies presume large metapopulations inhabiting noise-free, zero-extinction environments, and their predictions have never been empirically verified. Here we report an empirical study on the effects of localized perturbations on global dynamics and stability, using fruitfly metapopulations in the laboratory. We find that constant addition of individuals to a particular subpopulation in every generation stabilizes that subpopulation locally, but does not have any detectable effect on the dynamics and stability of the metapopulation. Simulations of our experimental system using a simple but widely applicable model of population dynamics were able to recover the empirical findings, indicating the generality of our results. We then simulated the possible consequences of perturbing more subpopulations, increasing the strength of perturbations, and varying the rate of migration, but found that none of these conditions were expected to alter the outcomes of our experiments. Finally, we show that our main results are robust to the presence of local extinctions in the metapopulation. Our study shows that localized perturbations are unlikely to affect the dynamics of real metapopulations, a finding that has cautionary implications for ecologists and conservation biologists faced with the problem of stabilizing unstable metapopulations in nature.
