title: Προσομοίωση διαδικασιών βασικής λειτουργίας αεροδορμίου

Creators: name: Κεκκης Βασιλειος
Publisher: name: Technical University of Crete
Year: 2019

description:    Η συγκεκριμένη εργασία εστιάζεται στην εφαρμογή της προσομοίωσης σε περιβάλλον αεροδρομίου και η καινοτομία της έγκειται στην παρακολούθηση ενός επιβάτη από τη στιγμή άφιξής του στο αεροδρόμιο μέχρι τη στιγμή αναχώρησής του με μια πτήση, παίρνοντας υπόψη όλα τα στάδια από τα οποία διέρχεται κατά την παραμονή του στο χώρο. Σημαντικό ρόλο στην όλη διαδικασία παίζουν οι παράπλευρες υποστηρικτικές λειτουργίες που είναι απαραίτητες για την ομαλή και έγκαιρη ολοκλήρωση της εξυπηρέτησης του επιβάτη, όπως π.χ. η διαδικασία του check-in επιβατών και αποσκευών, η διαχείριση των αποσκευών, η διαχείριση των εξόδων (gates), κλπ.  Η προσομοίωση θα υλοποιηθεί με το λογισμικό Extend Simulation και θα περιλαμβάνει τόσο γραφικά εργαλεία για την καλύτερη κατανόηση της λειτουργίας όσο και τη συλλογή στατιστικών δεδομένων για τη μελέτη της απόδοσης και τη σύγκριση εναλλακτικών στρατηγικών λειτουργίας.
   Στο μοντέλο προσομοίωσης που θα αναπτυχθεί ο αναλυτής θα εισάγει δεδομένα (εισροές) όπως:
•	Συγκεκριμένες διαδικασίες που προσομοιώνονται και πώς αυτές ιεραρχούνται και συνδέονται μεταξύ τους.
•	Τη διάρκεια κάθε στοιχειώδους διαδικασίας (μέσω κατάλληλης κατανομής πιθανότητας αν η διάρκεια είναι τυχαία).
•	Τους απαιτούμενους πόρους (μηχανήματα, ανθρώπινο δυναμικό, χώρους) για τη λειτουργία κάθε διαδικασίας.
•	Τη δυναμικότητα και ενδεχόμενους περιορισμούς διαθεσιμότητας των απαιτούμενων πόρων.
•	Τους χρονικούς περιορισμούς που προκύπτουν από τις προθεσμίες ολοκλήρωσης της διαδικασίας για κάθε επιβάτη (π.χ. ώρα αναχώρησης πτήσης).
Στη συνέχεια το πρόγραμμα θα εκτελεί την προσομοίωση, με δύο δυνατότητες. Η πρώτη δυνατότητα είναι η  παρακολούθηση μέσω φιλικής απεικόνισης. Ο αναλυτής παρακολουθεί μέσω της φιλικής απεικόνισης που προσφέρει το λογισμικό όλες τις κινήσεις που πραγματοποιούνται σε αυτό (π.χ. κινήσεις επιβατών μεταξύ ουρών αναμονής, κινήσεις υπαλλήλων μεταξύ διαφορετικών σταθμών εργασίας κλπ), ώστε να έχει πλήρη εποπτεία για το πώς λειτουργεί κάθε δραστηριότητα του μοντέλου. Η δεύτερη δυνατότητα παρακολούθησης αναφέρεται στη συλλογή στατιστικών στοιχείων σχετικά με τη λειτουργία του συστήματος. Αφού το μοντέλο εκτελεστεί με βάση τον δοσμένο χρόνο, προκύπτουν εκροές. Οι εκροές αυτές είναι στοιχεία όπως:
•	Η διάρκεια παραμονής σε ουρά αναμονής.
•	Μέσος χρόνος που διήρκησε η διαδικασία.
•	Αριθμός εκροών που προέκυψαν από το μοντέλου με την χρήση των δοσμένων εισροών.
   Οι πληροφορίες αυτές αποτελούν κλειδί για τον ενδιαφερόμενο γιατί βάση των αποτελεσμάτων μπορεί να τροποποιήσει τις εισροές και να επιφέρει σιγά σιγά το αποτέλεσμα που επιθυμεί. Βάσει του οποίου θα κατασκευάσει το σχέδιο δράσης για την πραγματικότητα

description: Glycolipids mediate stable membrane adhesion of potential biological relevance. In this article, we investigate the trans- and cis-interactions of glycolipids in molecular dynamics simulations and relate these interactions to the glycolipid-induced average separations of membranes obtained from neutron scattering experiments. We find that the cis-interactions between glycolipids in the same membrane leaflet tend to strengthen the trans-interactions between glycolipids in apposing leaflets. The trans-interactions of the glycolipids in our simulations require local membrane separations that are significantly smaller than the average membrane separations in the neutron scattering experiments, which indicates an important role of membrane shape fluctuations in glycolipid trans-binding. Simulations at the experimentally measured average membrane separations provide a molecular picture of the interplay between glycolipid attraction and steric repulsion of the fluctuating membranes probed in the experiments.

description: An accelerated cellular ageing has been observed in bipolar disorder (BD) using biomarkers such as telomere length (TL) and mitochondrial DNA copy number (mtDNAcn). Several risk factors might drive premature ageing in individuals with BD, including a familial predisposition. This study compared TL and mtDNAcn between individuals with BD and their (un)-affected siblings, and explored factors that may explain proband-sibling differences. Sixty individuals with BD and seventy-four siblings (34 affected with BD or mood disorders and 40 unaffected) were included. Quantitative polymerase chain reaction (qPCR) was used to measure TL and mtDNAcn from peripheral blood genomic DNA. TL and mtDNAcn did not significantly differ between probands and their siblings, whatever these latter were affected or not with mood disorders. However, the correlation plots of TL or mtDNAcn in proband-sibling pairs suggested that some pairs were discordant. The within proband-sibling pairs differences for TL and mtDNAcn were not explained by differences in all tested factors. This study shows that probands with BD and their siblings are concordant for TL and mtDNAcn suggesting that they may share some environmental or genetic determinants of these two biomarkers of cellular ageing.

Turbulent magnetic field amplification from the smallest to the largest magnetic Prandtl numbers

description: The small-scale dynamo provides a highly efficient mechanism for the conversion of turbulent into magnetic energy. In astrophysical environments, such turbulence often occurs at high Mach numbers, implying steep slopes in the turbulent spectra. It is thus a central question whether the small-scale dynamo can amplify magnetic fields in the interstellar or intergalactic media, where such Mach numbers occur. To address this long-standing issue, we employ the Kazantsev model for turbulent magnetic field amplification, systematically exploring the effect of different turbulent slopes, as expected for Kolmogorov, Burgers, the Larson laws and results derived from numerical simulations. With the framework employed here, we give the first solution encompassing the complete range of magnetic Prandtl numbers, including Pm << 1, Pm ~ 1 and Pm >> 1. We derive scaling laws of the growth rate as a function of hydrodynamic and magnetic Reynolds number for Pm << 1 and Pm >> 1 for all types of turbulence. A central result concerns the regime of Pm ~ 1, where the magnetic field amplification rate increases rapidly as a function of Pm. This phenomenon occurs for all types of turbulence we explored. We further find that the dynamo growth rate can be decreased by a few orders of magnitude for turbulence spectra steeper than Kolmogorov. We calculate the critical magnetic Reynolds number Rm_c for magnetic field amplification, which is highest for the Burgers case. As expected, our calculation shows a linear behaviour of the amplification rate close to the threshold proportional to Rm-Rm_c. Based on the Kazantsev model, we therefore expect the existence of the small-scale dynamo for any given value of Pm, as long as the magnetic Reynolds number is above the critical threshold.

description: Over the last few years, the chemistry of molecules other than CO in the planet-forming zones of disks is starting to be explored with Spitzer and high-resolution ground-based data. However, these studies have focused only on a few simple molecules. The aim of this study is to put observational constraints on the presence of more complex organic and sulfur-bearing molecules predicted to be abundant in chemical models of disks and to simulate high resolution spectra in view of future missions. High S/N Spitzer spectra at 10-30 micron of the near edge-on disks IRS46 and GVTau are used to search for mid-infrared absorption bands of various molecules. These disks are good laboratories because absorption studies do not suffer from low line/continuum ratios that plague emission data. Simple LTE slab models are used to infer column densities (or upper limits) and excitation temperatures. Bands of HCN, C2H2 and CO2 are clearly detected toward both sources. The HCN and C2H2 absorption arises in warm gas with Tex of 400-700 K, whereas the CO2 absorption originates in cooler gas of app. 250 K (as in Lahuis 2006). No other absorption features are detected. Limits of those molecules are determined and compared with disk models. The inferred ratios wrt. C2H2 and HCN are roughly consistent with models of the chemistry in high-T gas. Models of UV irradiated disk surfaces generally agree better than pure X-ray models. The limit on NH3/HCN implies that evaporation of NH3 containing ices is only a minor contributor. The inferred ratios also compare well with those found in comets, suggesting that part of the cometary material may derive from warm inner disk gas. High resolution simulations show that future instruments on JWST, ELTs, SOFIA and SPICA can probe up to an order of magnitude lower ratios and put important new constraints on the models, especially if pushed to high S/N ratios.

Power Allocation in Two-Hop Amplify-and-Forward MIMO Relay Systems with QoS requirements

description: The problem of minimizing the total power consumption while satisfying different quality-of-service (QoS) requirements in a two-hop multiple-input multiple-output network with a single non-regenerative relay is considered. As shown by Y. Rong in [1], the optimal processing matrices for both linear and non-linear transceiver architectures lead to the diagonalization of the source-relay-destination channel so that the power minimization problem reduces to properly allocating the available power over the established links. Unfortunately, finding the solution of this problem is numerically difficult as it is not in a convex form. To overcome this difficulty, existing solutions rely on the computation of upper- and lower-bounds that are hard to obtain or require the relaxation of the QoS constraints. In this work, a novel approach is devised for both linear and non-linear transceiver architectures, which allows to closely approximate the solutions of the non-convex power allocation problems with those of convex ones easy to compute in closed-form by means of multi-step procedures of reduced complexity. Computer simulations are used to assess the performance of the proposed approach and to make comparisons with alternatives.

description: We study the dynamic structure factor of a one-dimensional Bose gas confined in an optical lattice and modeled by the Bose-Hubbard Hamiltonian, using a variety of numerical and analytical approaches. The dynamic structure factor, experimentally measurable by Bragg spectroscopy, is studied in three relevant cases: in the clean regime, featuring either a superfluid or a Mott phase; and in the presence of two types of (quasi-)disordered external potentials: a quasi-periodic potential obtained from a bichromatic superlattice and a random-box disorder - both featuring a Bose glass phase. In the clean case, we show the emergence of a gapped doublon mode (corresponding to a repulsively bound state) for incommensurate filling, well separated from the low-energy acoustic mode. In the disordered case, we show that the dynamic structure factor provides a direct insight into the spatial structure of the excitations, unveiling their localized nature, which represents a fundamental signature of the Bose glass phase. Furthermore, it provides a clear fingerprint of the very nature of the localization mechanism which differs for the two kinds of disorder potentials we consider. In special cases, the dynamic structure factor may provide an estimate of the position of the localization transition from superfluid to Bose glass, in a complementary manner to the information deduced from the momentum distribution.

description: The main objective of this project deliverable is the preparation of data harmonisation guidelines for education research. The document is divided into two sections, the first section overviews the national and international data available in each partner country (Finland, Germany, Hungary, Ireland, Lithuania, Luxembourg, Norway, Spain and Switzerland). The goal being to provide an as comprehensive as possible list of the data sources that address education-related themes throughout the life course and provide relevant information concerning the focus of each study, it’s accessibility and it’s main target group(-s). The second section provides proposed harmonisations for the key variables across the surveys retained for empirical analysis (PIRLS, TIMSS, PISA, EUROSTUDENT VII, PIAAC, LIS, Growing up in Ireland, NEPS SC4, and TREE2). The variables include those pertinent to the main axes of educational inequalities (such as gender, socio-economic status, migration background) and variables that measure either directly or indirectly educational outcomes. Each variable is harmonised by conceptual content (based on the variable definitions that are as similar as possible) and by coding structure (using the same units of measurement and coding values).

The mosaic structure of the PZT leads to a coupling of the excited out-of-plane expansion to in-plane lattice dynamics on a picosecond timescale, which is not observed for out-of-plane compression.

description: We have studied Very Long Baseline Array (VLBA) polarimetric observations of 8 sources including quasars and BL Lacs at 12, 15, 22, 24 and 43 GHz and high frequency rotation measure ($RM$) maps are presented. We find typical values for the $RM$ in the VLBI core of several thousand rad/m$^2$, which are higher than values in the literature at lower frequencies. Assuming a dependence of the form $RM\propto ν^a$, we obtain an average value of $a=3.6\pm1.3$, which is larger than that expected by theoretical considerations. Rotation measures are detected in the jet of only two sources and we find that only 0906+430 (and possibly 1633+382) show indications of a robust gradient. We discuss the Faraday--corrected polarization properties of the sources. Our interpretation supports the presence of helical magnetic fields with new, unresolved, components affecting the intrinsic direction of polarization close to the base of the jet of some objects.

description: In a cloud computing environment, access control policy is an effective means of fortification cloud users and cloud resources services against security infringements. Based on analysis of current cloud computing security characteristics, the preamble of the concept of trust, role-based access control policy, combined with the characteristics of the cloud computing environment, there are multiple security management domains, so a new cross domain framework is for access control is proposed which is based on trust. It will establish and calculate the degree of trust in the single as well as multiple domains. Role Based Access Control is used for the implementation of the access control policies in a single domain environment with the introduction of the trust concept. In multiple domains the access control will be based on the conversion of roles. On the basis of trust, and role based access control model, a new novel framework of flexible cross domain access control framework is presented. The role assignment and conversion will take place dynamically.

description: We describe laser systems for photoionization, Doppler cooling and quantum state manipulation of beryllium ions. For photoionization of neutral beryllium, we have developed a continuous-wave 235 nm source obtained by two stages of frequency doubling from a diode laser at 940 nm. The system delivers up to 400 mW at 470 nm and 28 mW at 235 nm. For control of the beryllium ion, three laser wavelengths at 313 nm are produced by sum-frequency generation and second-harmonic generation from four infrared fiber lasers. Up to 7.2 W at 626 nm and 1.9 W at 313 nm are obtained using two pump beams at 1051 and 1551 nm. Intensity fluctuations below 0.5 % per hour (during 8 hours of operation) have been measured at a 313 nm power of 1 W. These systems are used to load beryllium ions into a segmented ion trap.

description: Non-linear dynamical systems involving small populations of individuals may sustain oscillations in the population densities arising from the discrete changes in population numbers due to random events. By applying these ideas to nanolasers operating with small numbers of emitting dipoles and photons at threshold, we show that such lasers should display photon and dipole population cycles above threshold, which should be observable as a periodic modulation in the second-order correlation function of the nanolaser output. Such a modulation was recently reported in a single-mode vertical-cavity surface-emitting semiconductor laser.

Gray-Tone Lithography Implementation of Drexhage's Method for Calibrating Radiative and Nonradiative Decay Constants of Fluorophores

description: We present a straightforward method to realize non-planar dielectric structures with a controlled height profile for use in calibration of fluorophores. Calibration of fluorescence quantum efficiency and intrinsic radiative and nonradiative decay rates of emitters is possible by using changes in the local density of optical states, provided one can control the emitter-surface distance with nanometer accuracy. We realize a method that is accurate yet fast to implement. We fabricate PMMA wedges (4 mm x 4 mm x 2 μm) by gray-tone UV-lithography of Shipley S1813G2. Its applicability as dielectric spacer is demonstrated in Drexhage experiments for three different emitters in the visible and near-infrared wavelength regime. The decay-rate dependence of the fluorescent state of emitters on the distance to a silver mirror is observed and compared to calculations based on the local density of states. Quantitative values for (non)radiative decay rates and quantum efficiencies are extracted. Furthermore, we discuss how Drexhage experiments can help to scrutinize the validity of effective material parameters of metamaterials in the near field regime.

description: In order to analyze data from cancer genome sequencing projects, we need to be able to distinguish causative, or "driver," mutations from "passenger" mutations that have no selective effect. Toward this end, we prove results concerning the frequency of neutural mutations in exponentially growing multitype branching processes that have been widely used in cancer modeling. Our results yield a simple new population genetics result for the site frequency spectrum of a sample from an exponentially growing population.

description: We examine the entropy of non-equilibrium stationary states of boundary driven totally asymmetric simple exclusion processes. As a consequence, we obtain that the Gibbs-Shannon entropy of the non equilibrium stationary state converges to the Gibbs-Shannon entropy of the local equilibrium state. Moreover, we prove that its fluctuations are Gaussian, except when the mean displacement of particles produced by the bulk dynamics agrees with the particle flux induced by the density reservoirs in the maximal phase regime.

description: Memristors are promising next-generation memory candidates that are nonvolatile, possess low power requirements and are capable of nanoscale fabrication. In this article we physically realise and describe the use of organic memristors in designing statefull boolean logic gates for the AND OR and NOT operations. The output of these gates is analog and dependent on the length of time that suitable charge is applied to the inputs, displaying a learning property. Results may be also interpreted in a traditional binary manner through use of a suitable thresholding function at the output. The memristive property of the gate allows the for the production of analog outputs that vary based on the charge-dependent nonvolatile state of the memristor. We provide experimental results of physical fabrication of three types of logic gate. A simulation of a one-bit full adder comprised of memristive logic gates is also included, displaying varying response to two distinct input patterns.
title: Considerations on the late Merovingian spatha suspension – a verifiable and wearable reconstruction

description: Bereits mehrfach wurde versucht, den Aufbau der spätmerowingerzeitlichen Spathaaufhängung zu rekonstruieren; dies geschah überwiegend anhand des Befundes eines einzelnen Grabes, zusätzlich erschwert durch den meist sehr schlechten Erhaltungszustand der ledernen Anteile. Für meinen Rekonstruktionsvorschlag habe ich nun die aussagekräftigen Befunde vereint und in ein dreidimensionales Modell überführt. Alle archäologisch nachgewiesenen Bestandteile sind dabei funktionell sinnvoll arrangiert. Die Verknüpfung der Scheide mit ihrer Aufhängung weise ich belegbar nach: Auch die Pyramidenknöpfe sind erstmals konkret von entscheidender Bedeutung. Mein Vorschlag ist auf alle auftretenden Varianten der verschiedenen Beschläge anwendbar. Die im Umgang mit den dreidimensionalen Rekonstruktionen gewonnenen Erkenntnisse in Bezug auf Handhabung und Tragekomfort ergeben ein schlüssiges Gesamtbild. Sie ermöglichen auch einen Blick auf die Kombination mit dem Sax, welcher in Gräbern der späten Merowingerzeit sehr häufig mit der Spatha vergesellschaftet war und somit die Trageweise der Spatha beeinflusst. Ferner beantworte ich die grundsätzliche Frage nach Hüft- oder Schultergurt eindeutig.
description: Several attempts have been made to reconstruct the late Merovingian spatha suspension; this mainly happening on evidence of single graves additionally impeded by the mainly very badly preserved leather components. For my sug - gested reconstruction I combined all relevant evidence and transferred it into a three-dimensional model. In doing so all parts which can be identified archaeologically are arranged in a functionally sensible way. I was able to prove the link between sheath and suspension: for the first time the pyramidal studs are of vital importance. My suggestion can be used for all existing variants of different fittings. On usage and comfortable transport of the weapon the results from the three-dimensional reconstruction lead to a conclusive overall picture. They also enable a view on the combination with the sax which often accompanies the spatha in the late Merovingian period and therefore influences the way of carrying the spatha. Furthermore the basic question of the waist and shoulder strap is answered clearly.
title: The bread offering from the Ipweger Moor – or why the prehistoric wagons were not destroyed by fire

description: Im nordöstlich der Stadt Oldenburg gelegenen Ipweger Moor musste 1989 der Teilbereich eines von der Zerstörung bedrohten Bohlenweges untersucht werden, der in die Zeit um 713/712v. Chr. datiert. Dabei konnte direkt unter dessen Bohlen ein Fundobjekt geborgen werden, das wegen seiner Form und der sich in seiner Oberfläche abzeichnenden Getreidereste als Brot interpretiert worden ist. Bei weiteren Untersuchungen hat sich dessen Substanz dann als Bienenwachs erwiesen, worauf in diesem Fundstück ein Brotimitat als Opfer an die Götter gesehen wurde. Diese Interpretation ist in der vorliegenden Arbeit überprüft worden, wobei sich unter Abwägung aller Befunde eine gänzlich andere Deutung ergibt, die letztlich auf einem sehr realistischen Hintergrund beruht.
description: In the Ipweger Moor, northeast of the town Oldenburg, a part of a wooden walkway from around 713/712BC – on the verge to destruction – was examined in 1989. In due course immediately beneath the blanks an object was rescued which was interpreted as bread for its shape and the remains of cereal showing on its surface. Further analyses demonstrated that it was bees wax and prompted the reading of the object as bread imitation intended for sacrifices to the gods. In the presented study this interpretation has been reviewed. Upon the consideration of all findings a com pletely different reading has been found basing on a very realistic background.
