description: We discuss unbiased estimation equations in a class of objective function using a monotonically increasing function $f$ and Bregman divergence. The choice of the function $f$ gives desirable properties such as robustness against outliers. In order to obtain unbiased estimation equations, analytically intractable integrals are generally required as bias correction terms. In this study, we clarify the combination of Bregman divergence, statistical model, and function $f$ in which the bias correction term vanishes. Focusing on Mahalanobis and Itakura-Saito distances, we provide a generalization of fundamental existing results and characterize a class of distributions of positive reals with a scale parameter, which includes the gamma distribution as a special case. We discuss the possibility of latent bias minimization when the proportion of outliers is large, which is induced by the extinction of the bias correction term.

description: Οι μέρες που διανύουμε χαρακτηρίζονται από αυξημένη οικολογική συνείδηση και η ανάγκη για εύρεση εναλλακτικών μεθόδων και υλικών που μπορούν να χρησιμοποιηθούν στην παραγωγή νέων δομικών υλικών κρίνεται απαραίτητη. Βασικός στόχος αυτής της έρευνας ήταν η παρασκευή δομικών υλικών με την χρήση βιομηχανικών παραπροϊόντων. Πιο συγκεκριμένα χρησιμοποιήθηκε ιπτάμενη τέφρα πλούσια σε ασβέστιο (τύπου C) που προμηθεύτηκε από το θερμικό σταθμό παραγωγής ηλεκτρικής ενέργειας της ΔΕΗ στη Πτολεμαΐδα και σκωρίας κάδου προερχόμενης από μεταλλουργική βιομηχανία scrap. Μελετήθηκαν δείγματα διαφόρων συστάσεων ιπτάμενης τέφρας / μεταλλουργικής σκωρίας κάδου καθώς επίσης ιπτάμενης τέφρας / Ca(OH)2. Οι θερμοκρασίες που επιλέχτηκαν για την υδροθερμική κατεργασία τους ήταν 95 και 60°C. Ερευνήθηκαν οι μηχανικές ιδιότητες των δειγμάτων (δυναμικό μέτρο ελαστικότητας Young, μέτρο διάτμησης, πυκνότητα, λόγος Poisson) και η μικροδομή τους ( ηλεκτρονικό σαρωτικό μικροσκόπιο, περιθλασίμετρο ακτίνων Χ). Τέλος τα αποτελέσματα που προέκυψαν αναλύθηκαν και συζητήθηκαν.
description: In our days the increased ecological conscience and the need to find alternative methods and materials than can be used in the production of new construction materials is crucial. The main aim of this research was the production of construction materials with use of industrial byproducts. More specifically the products used were fly ash rich in calcium (type C) that were supplied from the thermal power plant of the national electric company in Ptolemaida and the Ladle Furnace Slag that came from scrap metal industries. Samples with different compositions of fly ash / Ladle Furnace Slag and also fly ash / Ca(OH)2 were studied. The temperatures used for their hydrothermal treatment was 95 and 60°C. The mechanical properties of the samples were researched (Young Modulus, Shear modulus, density, Poisson ratio) and their microstructure (scanning electron microscope, X-ray Diffraction).Lastly the results were analyzed and discussed.

description: By combining analytic and numerical methods, edge states on a finite width graphene ribbon in a magnetic field are studied in the framework of low-energy effective theory that takes into account the possibility of quantum Hall ferromagnetism (QHF) gaps and dynamically generated Dirac-like masses. The analysis is done for graphene ribbons with both zigzag and armchair edges. The characteristic features of the spectrum of the edge states in both these cases are described. In particular, the conditions for the existence of the gapless edge states are established. Implications of these results for the interpretation of recent experiments are discussed.

description: Από το 2001 και μετέπειτα, η Ελλάδα, για άλλη μια φορά έρχεται αντιμέτωπη με αυξημένα ελλείμματα, που την οδήγησαν υπό καθεστώς επιτήρησης από την Ευρωπαϊκή Επιτροπή της Ευρωπαϊκής Οικονομικής και Νομισματικής Ένωσης. Η αντιμετώπιση της κατάστασης αυτής από την κυβέρνηση προφανώς απαιτεί πολύ καλή γνώση των δυναμικών χαρακτηριστικών των δύο βασικών ελληνικών ελλειμμάτων, του ελλείμματος του κρατικού προϋπολογισμού και του εμπορικού ελλείμματος. Ειδικότερα, απαιτείται η διερεύνηση του τρόπου σύνδεσης των δύο ελλε!ιμμάτων, δηλαδή ο προσδιορισμός της ύπαρξης αιτιωδών σχέσεων ανάμεσα τους, όπως και η κατεύθυνση των αιτιωδών επιδράσεων. Περαιτέρω, ιδιαίτερη σημασία έχει και η διερεύνηση της δυνατότητας της διαχρονικής διατήρησης τους σε ελεγχόμενα επίπεδα.Στην διεθνή βιβλιογραφία, τα παραπάνω, είναι γνωστά ως η υπόθεση των διδύμων ελλειμμάτων (twin deficits hypothesis) και η μελέτη της διατηρησιμότητας (sustainability) των ελλειμμάτων αυτών. Επιπλέον, και ενώ το 2002 η Ελλάδα αντιμετώπισε μία σημαντική θεσμική και διαρθρωτική αλλαγή, την είσοδο στην Ευρωπαϊκή Οικονομική και Νομισματική Ένωση, εντούτοις οι μελέτες στα ζητήματα που τέθηκαν ανωτέρω σταματούν στο 2000. Κατά συνέπεια, ο σκοπός της παρούσας μελέτης εστιάζει στην διερεύνηση των παραπάνω ζητημάτων για την Ελληνική οικονομία με νεότερα οικονομικά στοιχεία και στην κατάθεση συμπερασμάτων που θα μπορούσαν να χρησιμοποιηθούν από τους ασκούντες την οικονομική πολιτική.Στην παρούσα μελέτη χρησιμοποιήσαμε ετήσια στοιχεία για την ελληνική οικονομία της περιόδου 1960-2007 και εφαρμόζοντας την μέθοδο συνολοκλήρωσης της μέγιστης πιθανοφάνειας του Johansen (1988), καθώς και τους ελέγχους αιτιότητας του Granger (1969), προσπαθήσαμε να διερευνήσουμε και να δώσουμε απαντήσεις στα ανωτέρω ερωτήματα.Τα εμπειρικά μας ευρήματα δείχνουν την ύπαρξη «ασθενούς» διατηρησιμότητας και για τα δύο υπό εξέταση ελλείμματα και ακόμα επιβεβαιώνουν την παραδοσιακή προσέγγιση για τα δίδυμα ελλείμματα, με την ύπαρξη μακροχρόνιας αιτιώδους σχέσης μεταξύ τους και κατεύθυνση από το έλλειμμα του κρατικού προϋπολογισμού προς το εμπορικό έλλειμμα.
description: One of the most important open macroeconomics issues, during the current global economic turmoil and expanding recession, concerns the sustainability of persistent budget and trade deficits as well as possible interactions between them. These deficits are most crucial due to severe debt servicing costs, faced by today’s economies despite their development level. This paper presents time series evidence over the period 1960 up to 2007 using Greek data. Our results confirm “weak” sustainability of both deficits and evidence in favor of the Keynesian rationale regarding the “twin deficits hypothesis”.

description: We surveyed the Aquila Rift complex including the Serpens South and W40 region in the NH$_3$(1,1) and (2,2) transitions making use of the Nanshan 26-m telescope. The kinetic temperatures of the dense gas in the Aquila Rift complex range from 8.9 to 35.0K with an average of 15.3$\pm$6.1K. Low gas temperatures associate with Serpens South ranging from 8.9 to 16.8K with an average 12.3$\pm$1.7K, while dense gas in the W40 region shows higher temperatures ranging from 17.7 to 35.0K with an average of 25.1$\pm$4.9 K. A comparison of kinetic temperatures against HiGal dust temperatures indicates that the gas and dust temperatures are in agreement in the low mass star formation region of Serpens South. In the high mass star formation region W40, the measured gas kinetic temperatures are higher than those of the dust. The turbulent component of the velocity dispersion of NH$_3$(1,1) is found to be positively correlated with the gas kinetic temperature, which indicates that the dense gas may be heated by dissipation of turbulent energy. For the fractional total-NH3 abundance obtained by a comparison with Herschel infrared continuum data representing dust emission we find values from 0.1 to 21$\times 10^{-8}$ with an average of 6.9$(\pm 4.5)\times 10^{-8}$. Serpens South also shows a fractional total-NH3 abundance ranging from 0.2 to 21$\times 10^{-8}$ with an average of 8.6($\pm 3.8)\times 10^{-8}$. In W40, values are lower, between 0.1 and 4.3$\times 10^{-8}$ with an average of 1.6($\pm 1.4)\times 10^{-8}$. Weak velocity gradients demonstrate that the rotational energy is a negligible fraction of the gravitational energy. In W40, gas and dust temperatures are not strongly dependent on the projected distance to the recently formed massive stars. Overall, the morphology of the mapped region is ring-like, with strong emission at lower and weak emission at higher Galactic longitudes.

description: We present two different methods for modelling non-Markovian quantum light-matter interactions in waveguide QED systems, using matrix product states (MPSs) and a space-discretized waveguide (SDW) model. After describing the general theory and implementation of both approaches, we compare and contrast these methods directly on three topical problems of interest in waveguide-QED, including (i) a two-level system (TLS) coupled to an infinite (one-dimensional) waveguide, (ii) a TLS coupled to a terminated waveguide with a time-delayed coherent feedback, and (iii) two spatially separated TLSs coupled within an infinite waveguide. Both approaches are shown to efficiently model multi-photon nonlinear dynamics in highly non-Markovian regimes, and we highlight the advantages and disadvantages of these methods for modelling waveguide QED interactions, including their implementation in Python, computational run times, and ease of conceptual understanding. We explore both vacuum dynamics as well as regimes of strong optical pumping, where a weak excitation approximation cannot be applied. The MPS approach scales better when modelling multi-photon dynamics and long delay times, and explicitly includes non-Markovian memory effects. In contrast, the SDW model accounts for non-Markovian effects through space discretization, and solves Markovian equations of motion, yet rigorously includes the effects of retardation. The SDW model, based on an extension of recent collisional pictures in quantum optics, is solved through quantum trajectory techniques, and can more easily add in additional dissipation processes, including off-chip decay and TLS pure dephasing. The impact of these processes is shown directly on feedback-induced population trapping and TLS entanglement between spatially separated TLSs.

description: The correlated electronic structure of iron, cobalt and nickel is investigated within the dynamical mean-field theory formalism, using the newly developed full-potential LMTO-based LDA+DMFT code. Detailed analysis of the calculated electron self-energy, density of states and the spectral density are presented for these metals. It has been found that all these elements show strong correlation effects for majority spin electrons, such as strong damping of quasiparticles and formation of a density of states satellite at about -7 eV below the Fermi level. The LDA+DMFT data for fcc nickel and cobalt (111) surfaces and bcc iron (001) surface is also presented. The electron self energy is found to depend strongly on the number of nearest neighbors, and it practically reaches the bulk value already in the second layer from the surface. The dependence of correlation effects on the dimensionality of the problem is also discussed.

Dynamical flows through Dark Matter Haloes II: one and two points statistics at the virial radius

Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: In a serie of three papers, the dynamical interplay between environments and dark matter haloes is investigated, while focussing on the dynamical flows through their virial sphere. Our method relies on both cosmological simulations, to constrain the environments, and an extension to the classical matrix method to derive the response of the halo (see Pichon & Aubert (2006), paper I). The current paper focuses on the statistical characterisation of the environments surrounding haloes, using a set of large scale simulations. Our description relies on a `fluid' halocentric representation where the interactions between the halo and its environment are investigated in terms of a time dependent external tidal field and a source term characterizing the infall. The method is applied to 15000 haloes, with masses between 5 x 10^12 Ms and 10^14 Ms evolving between z = 1 and z = 0. The net accretion at the virial radius is found to decrease with time, resulting from both an absolute decrease of infall and from a growing contribution of outflows. Infall is found to be mainly radial and occurring at velocities ~ 0.75 V200. Outflows are also detected through the virial sphere and occur at lower velocities ~ 0.6 V200 on more circular orbits. The external tidal field is found to be strongly quadrupolar and mostly stationnary, possibly reflecting the distribution of matter in the halo's near environment. The coherence time of the small scale fluctuations of the potential hints a possible anisotropic distribution of accreted satellites. The flux density of mass on the virial sphere appears to be more clustered than the potential while the shape of its angular power spectrum seems stationnary.

description: Detrimental beam dynamics effects limit performance of high intensity rapid cycling synchrotrons (RCS) such as the 8 GeV proton Fermilab Booster. Here we report the results of comprehensive experimental studies of various beam intensity dependent effects in the Booster. In the first part, we report the dependencies of the Booster beam intensity losses on the total number of protons per pulse and on key operational parameters such as the machine tunes and chromaticities. Then we cross-check two methods of the beam emittance measurements (the multi-wires proportional chambers and the ionization profile monitors). Finally we used the intensity dependent emittance growth effects to analyze the ultimate performance of the machine in present configuration, with the maximum space-charge tuneshift parameter Qsc of 0.6, and after its injection energy is upgraded from 0.4 GeV to 0.8 GeV.

description: Following an eruptive accretion event in NGC6334I-MM1, flares in the various maser species, including water masers, were triggered. We report the observed relative proper motion of the highly variable water masers associated with the massive star-forming region, NGC6334I. High velocity H$_2$O maser proper motions were detected in 5 maser clusters, CM2-W2 (bow-shock structure), MM1-W1, MM1-W3, UCHII-W1 and UCHII-W3. The overall average of the derived relative proper motion is 85 km s$^{-1}$. This mean proper motion is in agreement with the previous results from VLA multi-epoch observations. Our position and velocity variance and co-variance matrix analyses of the maser proper motions show its major axis to have a position angle of $-$79.4$^\circ$, cutting through the dust cavity around MM1B and aligned in the northwest-southeast direction. We interpret this as the axis of the jet driving the CM2 shock and the maser motion. The complicated proper motions in MM1-W1 can be explained by the combined influence of the MM1 northeast-southwest bipolar outflow, CS(6-5) north-south collimated bipolar outflow, and the radio jet. The relative proper motions of the H$_2$O masers in UCHII-W1 are likely not driven by the jets of MM1B protostar but by MM3-UCHII. Overall, the post-accretion burst relative proper motions of the H$_2$O masers trace shocks of jet motion.

NFB kids: portrayals of children by the National Film Board of Canada, 1939-1989
Creators: name: Low, Brian John
Publisher: name: University of British Columbia
Year: 2009

description: Social historians have been understandably wary of the contents of motion pictures. Their reticence to use film as a socio-historical document stems from a valid assumption that, since almost every film is to some degree a fictional construction, no film or group of films may be said to accurately reflect a society. In this study, however, a society is presented that a historian may credibly claim to be accurately represented by film since it exists wholly in film. It is the cinematic society created by the film archives of the National Film Board of Canada (NFB). 'NFB society' is set in the 8,000 films produced since 1939 under the NFB mandate: "to interpret Canada to Canadians." Anchored physically, socially, and intellectually to the course of Canadian society and the state, this cinematic micro-society possesses a coherent Social history, which can be re-created by juxtaposing, synchronically and diachronically, films with like social scenarios. In so doing, patterns of social life, especially social relations in the micro-society may be observed in transience. NFB children play a significant role in this transience of NFB society, particularly in regard to dramatic changes in family, school, and community life which take place after the 1960s. Key to an explanation of the historical movement that develops within NFB families, schools, and communities are the 'progressive' socializing structures that replace traditional ones in the society in celluloid. Of particular interest are the social outcomes of the mental hygiene movement following its introduction into Film Board families in 1946 and schools in 1953. Over the decades of this study, the authority of NFB parents, teachers, and community leaders over the socialization of children is diminished by their adoption of the principles of mental hygiene, their influence over their children gradually supplanted by the influence of the cinematic state.

description: Many statistical models are algebraic in that they are defined by polynomial constraints or by parameterizations that are polynomial or rational maps. This opens the door for tools from computational algebraic geometry. These tools can be employed to solve equation systems arising in maximum likelihood estimation and parameter identification, but they also permit to study model singularities at which standard asymptotic approximations to the distribution of estimators and test statistics may no longer be valid. This paper demonstrates such applications of algebraic geometry in selected examples of Gaussian models, thereby complementing the existing literature on models for discrete variables.

description: Lakes are physical hollows , that include stable water and are supplied from rivers and torrents or springs. The most lakes of our country, were formed 20 million years ago. One of the biggest lakes of Greece, is lake Vegoritida. The present dissertation examines the torrential environment of lake Vegoritida and the human factors that led to the quantitative and qualitative degradation of this lake while it suggests solutions to confront effectively these problems. For this cause, the morphometric and hydrographical features of the Vegoritida’s watershed, which was separated into 26 individual watersheds, , the four basic torrential factors, the highest expected water flow and the highest expected sediment discharge, were determined. Then, the reasons that led to the fall of the lake’s level and its soiling, were mentioned. Finally, suggestions were made, to succeed the lake’s sanitation and recovery.

description: We investigate the subarea law scaling properties of the block entropy in bipartite fermionic systems which do not have a finite Fermi surface. It is found that in gapped regimes the leading subarea term is a negative constant, whereas in critical regimes with point nodes the leading subarea law is a logarithmic additive term. At the phase boundary that separates the critical and non-critical regimes, the subarea scaling shows power-law behavior.

Holographic Unification of Light and Gravity Through Quantum Information Holography
Creators: name: Padgett, Jason
Publisher: name: Zenodo
Year: 2024

description: The research intergrates Quantum Information Holography (QIH) with General Relativity (GR), offering a novel perspective on the unification of light and gravity. It specifically focuses on mapping Quantum state Vector (QSV) Tensor Fields from QIH onto Einstein's Vector Field in GR. This approach represents a signifigant stride in understanding how quantum mechanics and gravity might be interconnected.

In this framework, QSV's are conceptualized as the underlying structure of Hawking radiation- the theoretical radiation emitted by black holes. These QSVs are thought to carry angular frequency information, which is a quantum mechancial property, and are associated with Planck Qubits, the fundamental units in quantum information theory. The emitted Hawking radiation from entangled black holes, represented by these QSVs, is then translated into the language of GR through Einstein's Vector Field.

This translation is achieved by replacing the Einstein tensor, which describes the curvature of spacetime in GR, with an equivalent exspression derived from the QSV Tensor Field in QIH. This equivalent expression encompasses not just the curvature of spacetime but also integrates quantum concepts like velocity, acceleration and probability.

In essence, this approach suggests that the dynamics of quantum particles, as represented by QSV's and their probabilistic behavior, can be directly linked to the macroscopic phenomena of spacetime curvature and gravity as understood in GR. This unification hints at a deeper, underlying connectioin between quantum mechanics and general relativity, potentially paving the way for a more comprehensive understanding of the universe's fundamental forces.

description: A total 19% of generation capacity in California is offered by PV units and over some months, more than 10% of this energy is curtailed. In this research, a novel approach to reduce renewable generation curtailments and increasing system flexibility by means of electric vehicles' charging coordination is represented. The presented problem is a sequential decision making process, and is solved by fitted Q-iteration algorithm which unlike other reinforcement learning methods, needs fewer episodes of learning. Three case studies are presented to validate the effectiveness of the proposed approach. These cases include aggregator load following, ramp service and utilization of non-deterministic PV generation. The results suggest that through this framework, EVs successfully learn how to adjust their charging schedule in stochastic scenarios where their trip times, as well as solar power generation are unknown beforehand.

A novel approach to light-front perturbation theory

description: We suggest a possible algorithm to calculate one-loop n-point functions within a variant of light-front perturbation theory. The key ingredients are the covariant Passarino-Veltman scheme and a surprising integration formula that localises Feynman integrals at vanishing longitudinal momentum. The resulting expressions are generalisations of Weinberg's infinite-momentum results and are manifestly Lorentz invariant. For n = 2 and 3 we explicitly show how to relate those to light-front integrals with standard energy denominators. All expressions are rendered finite by means of transverse dimensional regularisation.

description: Η καινοτομική δραστηριότητα μιας περιφέρειας είναι από τα βασικότερα στοιχειά που επηρεάζουν την ανάπτυξη της. Στην έρευνα μας προσπαθούμε να δούμε την συγκέντρωση αυτής της καινοτομικής δραστηριότητας σε 207 περιφέρειες της Ευρωπαϊκής Ένωσης των δεκαπέντε.Δεν έχει γίνει κάποια σχετική έρευνα σε αυτό το επίπεδο γι’ αυτό δεν έχουμε βασιστεί σε κάποιο συγκεκριμένο άρθρο.Γενικά, σε όλα τα άρθρα που μελετήσαμε, για την προσέγγιση του βαθμού συγκέντρωσης της βιομηχανικής οργάνωσης, διαπιστώσαμε ότι χρησιμοποιούνται οι δείκτες συγκέντρωσης.Εμείς χρησιμοποιούμε στην ανάλυση μας τον λόγο συγκέντρωσης (CR4) των τεσσάρων πιο καινοτομικών κλαδών, τον δείκτη συγκέντρωσης του Herfindahl που χρησιμοποιείται στις περισσότερες αναφορές και τον δείκτη Εντροπίας που δεν χρησιμοποιείται σε μεγάλο βαθμό. Τo χρονικό διάστημα που αναλύουμε είναι από το 1995-2005 και στην συνέχεια, για κάθε περιφέρεια βρίσκουμε τον μέσο όρο across time and classes των πατεντών και ομαδοποιούμε της περιφέρειες σε πέντε quintile συμφώνα με αυτό.Από την έρευνα διαπιστώνουμε ότι, όσο πιο καινοτομική είναι μια περιφέρεια, τόσο λιγότερο συγκεντρωμένη είναι. Επίσης οι περιφέρειες ταυτίζονται περισσότερο μεταξύ τους όταν είναι λιγότερο καινοτομικές.
description: The innovative activity is one of the key elements that affect its development. In our research we try to see the concentration of innovative activity in 207 regions of the European Union of fifteen. There has been some research in this area so we are not based on any particular article. Generally,in all the articles that we studied to approximate the degree of concentration of industrial organization we found that the most useful for this measure are the concetration index. We use in our analysis the concentration ratio (CR4) of the four most innovative industry, the Herfindahl index of concentration used in most reports and the entropy index that is not widely used .The period analyzed is from 1995-2005 and then for each region we find the average across time and classes of patents and we group regions into five quintile according to this. From the research we find that, the more innovative is a region, the less concentrated it is. Also, regions are more identical between them when they are less innovative.

A novel estimand to adjust for rescue treatment in clinical trials

description: The interpretation of randomised clinical trial results is often complicated by intercurrent events. For instance, rescue medication is sometimes given to patients in response to worsening of their disease, either in addition to the randomised treatment or in its place. The use of such medication complicates the interpretation of the intention-to-treat analysis. In view of this, we propose a novel estimand defined as the intention-to-treat effect that would have been observed, had patients on the active arm been switched to rescue medication if and only if they would have been switched when randomised to control. This enables us to disentangle the treatment effect from the effect of rescue medication on a patient's outcome, while avoiding the strong extrapolations that are typically needed when inferring what the intention-to-treat effect would have been in the absence of rescue medication. We develop an inverse probability weighting method to estimate this estimand under specific untestable assumptions, in view of which we propose a sensitivity analysis. We use the method for the analysis of a clinical trial conducted by Janssen Pharmaceuticals, in which chronically ill patients can switch to rescue medication for ethical reasons. Monte Carlo simulations confirm that the proposed estimator is unbiased in moderate sample sizes.

description: An asymptotic treatment of thin accretion disks, introduced by Kluźniak & Kita (2000) for a steady-state disk flow, is extended to a time-dependent problem. Transient growth of axisymmetric disturbances is analytically shown to occur on the global disk scale. The implications of this result on the theory of hydrodynamical thin accretion disks, as well as future prospects, are discussed.

description: Η παρούσα εργασία πραγματεύεται το θέμα της ανάπτυξης ενός Συστήματος Διαχείρησης Αποθεμάτων για τη συντήρηση βιομηχανιών. Ειδικότερα, αναπτύσσεται ένα Αυτοματοποιημένο Σύστημα Διαχείρισης Συντήρησης, η μελέτη του οποίου βασίστηκε πάνω στο τμήμα συντήρησης της εταιρίας ISOMAT ΑΒΕΕ και στις ανάγκες του. Καλύπτει τις ανάγκες της εταιρίας σε ότι αφορά στις καταχωρήσεις που πρέπει να έχει ένα σύστημα οργάνωσης αποθεμάτων, δίνοντας ιδιαίτερη βαρύτητα στις διαδικασίες που ακολουθούνται.Στόχος της ανάλυσης που έγινε ήταν να υλοποιηθεί ένα σύστημα με το ελάχιστο δυνατό κόστος και τη μέγιστη δυνατή λειτουργικότητα. Μετά τη σχετική μελέτη της βιβλιογραφίας και των συστημάτων που ήδη κυκλοφορούν στην αγορά, επιλέχθηκε το SugarCRM, ένα λογισμικό ανοιχτού κώδικα το οποίο παραμετροποιήθηκε και επεκτάθηκε αναλόγως. Πέρα από την παραμετροποιήση, αναπτύχθηκαν και νέα τμήματα λογισμικού ώστε να ικανοποιηθούν όλες απαιτήσεις του συστήματος. Η τελική “πινελιά” στο IMS (ISOMAT Maintenance System) δόθηκε με επέμβαση στον κώδικα του προγράμματος, έτσι ώστε να δοθεί η απαραίτητη έμφαση στις ανάγκες των τελικών χρηστών και στη λειτουργικότητα σε πραγματικές συνθήκες. Το πρόγραμμα αυτή τη στιγμή βρίσκεται σε πειραματική φάση εγκατάστασης και εκπαίδευσης του προσωπικού.
description: This thesis addresses the issue of developing an Enterprize Recource Planning System for maintenance industries. A Computerized Maintenance Management System was developed, based on the needs and requirements of the maintenance department of ISOMAT SA. It satisfies the company needs with respect to the entries that an ERP should have, giving particular emphasis on the procedures that are followed. The analysis performed aimed at creating a system with the lowest cost and the maximum functionality possible. Having performed a state-of-the-art review on the commercial and open-source systems available, SugarCRM was selected, an open-source ERP platform that was further parameterized and extended. Apart from the parameterization, new software modules were developed in order to fully satisfy system requirements. The final “touch” at IMS (ISOMAT Maintenance System) was given at raw code level, so as to best focus on the end-user needs and real case functionality. The program is currently deployment as a pilot and staff is being trained on it.
