description: Based on cluster de-synchronization properties of phase oscillators, we introduce an efficient method for the detection and identification of modules in complex networks. The performance of the algorithm is tested on computer generated and real-world networks whose modular structure is already known or has been studied by means of other methods. The algorithm attains a high level of precision, especially when the modular units are very mixed and hardly detectable by the other methods, with a computational effort ${\cal O}(KN)$ on a generic graph with $N$ nodes and $K$ links.

description: The two-dimensional electron gas found at the surface of SrTiO$_3$ and related interfaces has attracted significant attention as a promising basis for oxide electronics. In order to utilize its full potential, the response of this 2DEG to structural changes and surface modification must be understood in detail. Here, we present a study of the detailed electronic structure evolution of the 2DEG as a function of sample temperature and surface step density. By comparing our experimental results with \textit{ab initio} calculations, we found that a SrO-rich surface layer is a prerequisite for electronic confinement. We also show that local structure relaxations cause a metal-insulator transition of the system around 135~K. Our study presents a new and simple way of tuning the 2DEG via surface vicinality and identifies how the operation of prospective devices will respond to changes in temperature.

description: Η διαχείριση των στερεών αποβλήτων είναι ιδιαίτερα δύσκολη στα ελληνικά νησιά και ακόμη περισσότερο στην Σαντορίνη, λόγω του μικρού μεγέθους της και της αύξησης του πληθυσμού (τουρίστες) κυρίως κατά τη διάρκεια μιας εκτεταμένης θερινής περιόδου που κάνουν τη διαχείριση των απορριμμάτων πιο προκλητική. Ο σκοπός της διπλωματικής εργασίας είναι να αναδείξει τον επείγοντα χαρακτήρα του θέματος και να προτείνει άμεσα εφαρμόσιμες λύσεις για να ενισχυθεί περαιτέρω η ανακύκλωση στο νησί. Η υφιστάμενη κατάσταση διαχείρισης των αποβλήτων παρουσιάζεται και οι ελλείψεις του συστήματος αναλύονται. Η διπλωματική εργασία επικεντρώνεται στην έρευνα που έχει γίνει σχετικά με τα μέτρα που θα παρακινήσουν αποτελεσματικά τις επιχειρήσεις να ανακυκλώνουν περισσότερο που, λόγω του τεράστιου αριθμού τους, διαδραματίζουν σημαντικό ρόλο στις οικονομικές δραστηριότητες του νησιού. Συγκεκριμένα έγινε παραγοντική ανάλυση με χρήση του προγράμματος IBM SPSS Statistics 24 των παραμέτρων που αφορούν την υφιστάμενη κατάσταση καθώς και τα κίνητρα ή αντικίνητρα για αύξηση του ποσοστού ανακυκλώσιμων υλικών στο νησί. Επίσης προτείνεται ένας οδηγός ο οποίος θα βοηθήσει τις επιχειρήσεις να αυξήσουν το ποσοστό των ανακυκλώσιμων υλικών που χρησιμοποιούν.
description: The management of solid waste is especially challenging on the Greek islands and even more on Santorini, due to its small size and the increased population (tourists) mostly during an extensive summer period that make the waste management more challenging. The objective of the paper is to highlight the urgency of the matter and to suggest immediately applicable solutions to further boost recycling on the island. The existing situation of waste management is presented and the deficiencies of the system are analyzed. The thesis focuses on the survey that has been done regarding the measures that will effectively motivate the businesses to recycle more who, due to its huge number, play an important role to the economic activities of the island. Specifically a factor analysis has been implemented using IBM SPSS Statistics 24 program with parameters relating to the current situation and the incentives or disincentives to increase the percentage of recyclable materials on the island. Furthermore a guide is proposed which will help the enterprises to increase the percentage of the recyclable materials they use.

description: In this article we give a short introduction to the online method of event-related (brain) potentials (ERPs) and their importance for our understanding of language structure and grammar. This methodology places high demands on (technical) requirements for laboratory equipment as well as on the skills of the investigator. However, the high costs are relatively balanced compared to the advantages of this experimental method. By using ERPs, it becomes possible to monitor the electrophysiological brain activity associated with speech processing in real time (millisecond by millisecond) and to draw conclusions on human language processing and the human parser. First, we present briefly how this method works and how ERPs can be classified (Section 1 and 2). In the following, we show that the ERP method can be used to study the processing of e. g. semantic, pragmatic and syntactic information (Section 3). Crucial for our discussion will be the interpretation of the so-called ERP components and their connection and importance for psycholinguistics and theoretical linguistics. In our presentation, we emphasize, that the electrophysiological brain activity in relation to specific (e. g. linguistic) stimuli can be used to identify distinct processes, which give a deeper insight into the different processing steps of language. At the end of this article (Section 4), we present some results from ERP studies of German negative-polar elements. Additionally, we highlight the advantage and benefits of an alternative method to analyze ERP data compared to the more ‘classical’ average technique.
Marker analysis for the detection of metastatic breast cancer
Creators: name: Hornby, Ann Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: The main objective of this thesis was to examine the possibility of transferring the current immunologic methods of detecting metastatic breast cancer to a more specific, more sensitive, and less subjective nucleic acid-based technology. The rational was two-fold: (1) early detection of metastatic disease may be useful in determining treatment protocols for breast cancer patients; and (2) the ability to detect small numbers of tumor cells in blood or bone marrow may help in monitoring the effectiveness of treatment. Chronic myelogenous leukemia (CML) was successfully used as a model system for the development of PCR for the detection of rare mRNAs expressed in blood or bone marrow. The level of sensitivity achieved was 1/10⁶ cells. Once the PCR technology was established CML bone marrow was then used to study the effect of Benzoporphyrin derivative mono acid-A (BPD-MA) on the enzymatic activity of Taq polymerase. BPD-MA is a photoactive drug being developed by Quadra Logic Technologies Ltd., with potential use as a bone marrow purging agent for patients with metastatic breast cancer undergoing autologous bone marrow transplantation. BPD-MA did not interfere with the ability of Taq polymerase to detect rare mRNA expression in bone marrow, therefore PCR technology could be used to monitor the effectiveness of treatment after bone marrow purging and autologous bone marrow transplantation. Using RNA PCR technology the expression of three genes currently used for the detection of metastatic breast cancer by immunological methods was studied. Polymorphic epithelial mucin gene expression was analyzed in breast cancer cell lines, and normal blood and bone marrow. No expression was detected in bone marrow; however, expression was detected in peripheral blood. This may account for reports of cross-reactivity of mAbs directed against epithelial mucins detected in peripheral blood. Keratin 18 and 8 expression was analyzed in a similar manner. Keratin 18 expression was detected in both blood and bone marrow, whereas, keratin 8 expression was detected in blood only. The expression of both keratins appeared to be the result of transcriptionally active processed pseudogenes. Keratin 8 pseudogene expression also appeared to be differentially regulated in breast versus peripheral blood cells.

description: We report the discovery of a cluster-scale lensed quasar, SDSS J1029+2623, selected from the Sloan Digital Sky Survey. The lens system exhibits two lensed images of a quasar at z_s=2.197. The image separation of 22.5" makes it the largest separation lensed quasar discovered to date. The similarity of the optical spectra and the radio loudnesses of the two components support the lensing hypothesis. Images of the field show a cluster of galaxies at z_l~0.55 that is responsible for the large image separation. The lensed images and the cluster light center are not collinear, which implies that the lensing cluster has a complex structure.

description: We present an optical study of the strong lensing galaxy cluster MS 0440.5$+$0204 at $z=0.19593$, based on CFHT/MegaCam g', r'-photometry and GMOS/Gemini and CFHT/MOS/SIS spectroscopy in a broader area compared to previous works. We have determined new spectroscopic redshifts for the most prominent gravitational arcs surrounding the central galaxy in the cluster. The new redshifts and the information provided by the photometric catalog yield us to perform a detailed weak and strong lensing mass reconstruction of the cluster. The large number of member galaxies and the area covered by our observations allow to estimate more accurately the velocity dispersion and mass of cluster and examine in detail the nature of the cluster and surroundings structures. The dynamical mass is in good agreement with the mass inferred from the lensing analysis and X-ray estimates. About $\sim$68\% of the galaxies are located in the inner $\lesssim$0.86 h$^{-1}_{70}$ Mpc region of the cluster. The galaxy redshift distribution in the inner region of the cluster shows a complex structure with at least three sub-structures along the line-of-sight. Other sub-structures are also identified in the galaxy density map and in the weak lensing mass map. The member galaxies in the North-East overdensity are distributed in a filament between MS 0440.5$+$0204 and ZwCL 0441.1$+$0211 clusters, suggesting that these two structures might be connected. MS 0440$+$0204 appears to be dynamically active, with a cluster core that is likely experiencing a merging process and with other nearby groups at projected distances of $\lesssim$1 h$^{-1}_{70}$ Mpc that could be being accreted by the cluster.

description: With high efficiency and good scalability, Robotic Mobile Fulfilment Systems (RMFS) are increasingly applied in various warehouses, especially the e-commerce warehouses with rigid order completion time. RMFS requires less workers and provide more punctual service for customers. The existing literature on RMFS is based on single-deep non-compact layout. As land supply is limited and expensive in urban area, it’s essential to consider compact storage in RMFS. This paper is the first to model and evaluate the multi-deep compact RMFS. We develop a semi-open queueing network (SOQN) model to characterise the multi-deep compact RMFS and solve it by Approximate Mean Value Analysis (AMVA). The obtained approximate analytic solutions of system throughput, robot utilisation, and queue length were verified and assessed through simulations. The numerical experiments investigated the effects of different configuration of the lane depth, number of picking aisles, arrangement of picking stations and the number of robots on performance. Our research can provide useful guidelines for warehouse planners and managers for designing and operating multi-deep compact RMFS.

description: We present in closed form some special travelling-wave solutions (on the real line or on the circle) of a perturbed sine-Gordon equation. The perturbation of the equation consists of a constant forcing term $γ$ and a linear dissipative term, and the equation is used to describe the Josephson effect in the theory of superconductors and other remarkable physical phenomena. We determine all travelling-wave solutions with unit velocity (in dimensionless units). For $|γ|$ not larger than 1 we find families of solutions that are all (except the obvious constant one) manifestly unstable, whereas for $|γ|>1$ we find families of stable solutions describing each an array of evenly spaced kinks.

description: Particle-in-cell codes are the most widely used simulation tools for kinetic studies of ultra-intense laser-plasma interactions. Using the motion of a single electron in a plane electromagnetic wave as a benchmark problem, we show surprising deterioration of the numerical accuracy of the PIC algorithm with increasing normalized wave amplitude for typical time-step and grid sizes. Two significant sources of errors are identified: strong acceleration near stopping points and the temporal field interpolation. We propose adaptive electron sub-cycling coupled with a third order temporal interpolation of the magnetic field and electric field as an efficient remedy that dramatically improves the accuracy of the particle integrator.

description: Early analyses of exoplanet statistics from the Kepler Mission revealed that a model population of multiple-planet systems with low mutual inclinations (${\sim1^{\circ}-2^{\circ}}$) adequately describes the multiple-transiting systems but underpredicts the number of single-transiting systems. This so-called "Kepler dichotomy" signals the existence of a sub-population of multi-planet systems possessing larger mutual inclinations. However, the details of these inclinations remain uncertain. In this work, we derive constraints on the intrinsic mutual inclination distribution by statistically exploiting Transit Duration Variations (TDVs) of the Kepler planet population. When planetary orbits are mutually inclined, planet-planet interactions cause orbital precession, which can lead to detectable long-term changes in transit durations. These TDV signals are inclination-sensitive and have been detected for roughly two dozen Kepler planets. We compare the properties of the Kepler observed TDV detections to TDV detections of simulated planetary systems constructed from two population models with differing assumptions about the mutual inclination distribution. We find strong evidence for a continuous distribution of relatively low mutual inclinations that is well-characterized by a power law relationship between the median mutual inclination ($\tildeμ_{i,n}$) and the intrinsic multiplicity ($n$): $\tildeμ_{i,n} = \tildeμ_{i,5}(n/5)^α$, where $\tildeμ_{i,5} = 1.10^{+0.15}_{-0.11}$ and $α= -1.73^{+0.09}_{-0.08}$. These results suggest that late-stage planet assembly and possibly stellar oblateness are the dominant physical origins for the excitation of Kepler planet mutual inclinations.

description: This study examines the phaenomenon of antimicrobial resistance. Resistance to antibiotics has rendered traditional therapeutic approaches to certain bacterial infections inadequate and led to increased morbidity and mortality worldwide. The first part of the study discusses the evolution of antibiotics, the current state of medical research for new antibiotic substances and the development of antimicrobial resistance. The role of the clinical microbiology laboratory in the selection of suitable substances, in order to control antimicrobial resistance is, also, approached. The main part of the study analyses the acceleration mechanisms of antimicrobial resistance, which mainly concern the use and administration of antimicrobial drugs. Furthermore, it comments on the current form of the global and European microbial resistance maps and presents their evolution during the period of the phaenomenon’s official monitoring. The last part of the study outlines the Greek legal framework covering the use of antibiotics and infection control and concludes by presenting bioethical concerns in conjunction with antimicrobial resistance as well as the prevention and management policies adopted by international monitoring organisations.
Flux-transport dynamos with Lorentz force feedback on differential rotation and meridional flow: Saturation mechanism and torsional oscillations
Creators: name: Rempel, Matthias
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we discuss a dynamic flux-transport dynamo model that includes the feedback of the induced magnetic field on differential rotation and meridional flow. We consider two different approaches for the feedback: meanfield Lorentz force and quenching of transport coefficients such as turbulent viscosity and heat conductivity. We find that even strong feedback on the meridional flow does not change the character of the flux-transport dynamo significantly; however it leads to a significant reduction of differential rotation. To a large degree independent from the dynamo parameters, the saturation takes place when the toroidal field at the base of the convection zone reaches between 1.2 an 1.5 T, the energy converted intomagnetic energy corresponds to about 0.1 to 0.2% of the solar luminosity. The torsional oscillations produced through Lorentz force feedback on differential rotation show a dominant poleward propagating branch with the correct phase relation to the magnetic cycle. We show that incorporating enhanced surface cooling of the active region belt (as proposed by Spruit) leads to an equatorward propagating branch in good agreement with observations.

Single-Scan Min-Sum Algorithms for Fast Decoding of LDPC Codes
Creators: name: Huang, Xiaofei
Publisher: name: arXiv
Year: 2006
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Many implementations for decoding LDPC codes are based on the (normalized/offset) min-sum algorithm due to its satisfactory performance and simplicity in operations. Usually, each iteration of the min-sum algorithm contains two scans, the horizontal scan and the vertical scan. This paper presents a single-scan version of the min-sum algorithm to speed up the decoding process. It can also reduce memory usage or wiring because it only needs the addressing from check nodes to variable nodes while the original min-sum algorithm requires that addressing plus the addressing from variable nodes to check nodes. To cut down memory usage or wiring further, another version of the single-scan min-sum algorithm is presented where the messages of the algorithm are represented by single bit values instead of using fixed point ones. The software implementation has shown that the single-scan min-sum algorithm is more than twice as fast as the original min-sum algorithm.

description: During each ovarian cycle, only a definite number of follicles ovulate, while the others undergo a degeneration process called atresia. We have designed a multi-scale mathematical model where ovulation and atresia result from a hormonal controlled selection process. A 2D-conservation law describes the age and maturity structuration of the follicular cell population. In this paper, we focus on the operating mode of the control, through the study of the characteristics of the conservation law. We describe in particular the set of microscopic initial conditions leading to the macroscopic phenomenon of either ovulation or atresia, in the framework of backwards reachable sets theory.

description: The measurement of the angle between the interferometer front mirror and the diffracting planes is a critical aspect of the Si lattice-parameter measurement by combined x-ray and optical interferometry. In addition to being measured off-line by x-ray diffraction, it was checked on-line by transversely moving the analyser crystal and observing the phase shift of the interference fringe. We describe the measurement procedure and give the miscut angle of the $^{28}$Si crystal whose lattice parameter was an essential input-datum for, yesterday, the determination of the Avogadro constant and, today, the kilogram realisation by counting atoms. These data are a kindness to others that might wish to repeat the measurement of the lattice-parameter of this unique crystal.

description: I show that the so-called causality paradox of time-dependent density functional theory arises from an incorrect formulation of the variational principle for the time evolution of the density. The correct formulation not only resolves the paradox in real time, but also leads to a new expression for the causal exchange-correlation kernel in terms of Berry curvature. Furthermore, I show that all the results that were previously derived from symmetries of the action functional remain valid in the present formulation. Finally, I develop a model functional theory which explicitly demonstrates the workings of the new formulation.

description: Σκοπός της εργασίας ήταν η μελέτη των παραστάσεων του Κάρλο Γκολντόνι στη σκηνή του Κρατικού Θεάτρου Βορείου Ελλάδος. Πιο συγκεκριμένα, επιθυμία μας ήταν να εντοπίσουμε και να κατανοήσουμε τη διάδοση και την πρόσληψη του Ιταλού συγγραφέα, τόσο από μέρους του κοινού, όσο και από τους παράγοντες της θεατρικής δραστηριότητας, στο Κρατικό Θέατρο Βορείου Ελλάδος. Επιχειρήθηκε μια οριοθέτηση του ιστορικού πλαισίου, μέσα στο οποίο εντάσσεται η διάδοση του έργου του Ιταλού συγγραφέα και μελετήθηκαν οι πρώτες μεταφράσεις στα Ελληνικά, των έργων του. Επιχειρήθηκε μια περιοδολόγηση των παραστάσεων του Γκολντόνι, στο Κ.Θ.Β.Ε, και η ανάλυσή τους, όσον αφορά, στη μετάφραση, στη σκηνοθεσία, στα δημοσιεύματα του Τύπου (με ιδιαίτερη προσοχή στα κοστούμια, στα σκηνικά, στη μουσική και στους ηθοποιούς).
description: The aim of the present thesis was the study of stage performances of Carlo Goldoni at the National Theater of Nothern Greece. More specifically, our goal was to identify and understand the diffusion and the comprehension of the Italian writer, both by the public and by the experts of the theatrical activity, at the National Theater of Northern Greece. We have attempted to define, the historical context in which the work of the Italian writer is placed and we have studied the first translations of his works, in Greek. We have also tried to achieve a periodization of Goldoni’s plays at the N.T.N.G., and to analyze, the translations used on stage, the stage directions of the performances, and some important articles of the Press (with particular attention to the costumes, the scenery, the music and the actors).

description: The population of elderly people has been increasing at a rapid rate over the last few decades and their population is expected to further increase in the upcoming future. Their increasing population is associated with their increasing needs due to problems like physical disabilities, cognitive issues, weakened memory and disorganized behavior, that elderly people face with increasing age. To reduce their financial burden on the world economy and to enhance their quality of life, it is essential to develop technology-based solutions that are adaptive, assistive and intelligent in nature. Intelligent Affect Aware Systems that can not only analyze but also predict the behavior of elderly people in the context of their day to day interactions with technology in an IoT-based environment, holds immense potential for serving as a long-term solution for improving the user experience of elderly in smart homes. This work therefore proposes the framework for an Intelligent Affect Aware environment for elderly people that can not only analyze the affective components of their interactions but also predict their likely user experience even before they start engaging in any activity in the given smart home environment. This forecasting of user experience would provide scope for enhancing the same, thereby increasing the assistive and adaptive nature of such intelligent systems. To uphold the efficacy of this proposed framework for improving the quality of life of elderly people in smart homes, it has been tested on three datasets and the results are presented and discussed.

description: A non-Abelian version of the Hirota-Miwa equation is considered. In an earlier paper [Nimmo (2006) J. Phys. A: Math. Gen. \textbf{39}, 5053-5065] it was shown how solutions expressed as quasideterminants could be constructed for this system by means of Darboux transformations. In this paper we discuss these solutions from a different perspective and show that the solutions are quasi-Plücker coordinates and that the non-Abelian Hirota-Miwa equation may be written as a quasi-Plücker relation. The special case of the matrix Hirota-Miwa equation is also considered using a more traditional, bilinear approach and the techniques are compared.

description: We perform ab initio density functional calculations to study the flow of water, methanol and dimethyl ether through nanotubes of carbon and boron nitride with different diameters and chiralities. The liquids we choose are important solvents, with water and methanol being polar and dimethyl ether being non-polar. In terms of activation barriers for liquid transport, we find the molecular-level drag to decrease with decreasing nanotube diameter, but to be rather independent of the chiral index. We also find molecules with higher polarity to experience higher drag during the flow. Counter-intuitively, we find the drag for water in boron nitride nanotubes not to exceed that in carbon nanotubes due to frustration in competing long-range Coulomb interactions.

description: Η παρούσα εισήγηση επιχειρεί μία διείσδυση στο ζήτημα της απονομής των αναπηρικών συντάξεων στην Ελλάδα. Το μεγαλύτερο μέρος της μελέτης αφιερώνεται στο νομοθετικό καθεστώς που διέπει το Ίδρυμα Κοινωνικών Ασφαλίσεων, ενώ δίνεται συνεχώς έμφαση στη συμβολή της νομολογίας του Συμβουλίου της Επικρατείας. Πιο συγκεκριμένα, εξετάζονται διεξοδικά οι έννοιες της ιατρικής και της ασφαλιστικής αναπηρίας, όπως αυτές αρχικά διαμορφώθηκαν και εξελίχθηκαν έως σήμερα, τα ειδικότερα χαρακτηριστικά τους, οι υποχρεώσεις των αιτούντων συνταξιοδότηση λόγω αναπηρίας και οι ειδικές προϋποθέσεις τις οποίες αυτοί πρέπει να πληρούν. Ακόμη, αναδεικνύονται φλέγοντα ζητήματα, όπως η δυνατότητα επαγγελματικής επανένταξης των ανάπηρων συνταξιούχων και η σημασία των αποφάσεων των διοικητικών οργάνων κατά την παροχή εννόμου προστασίας στους ενδιαφερόμενους, καθώς και οι ανακύπτουσες προβληματικές και τα μελανά σημεία της διαδικασίας απονομής των αναπηρικών συντάξεων, συλλήβδην. Τέλος, γίνεται μία αποτίμηση, από κοινωνικής άποψης, του συστήματος.
description: The present paper attempts a penetration into the issue of the award of disability pensions in Greece. The biggest part of the study is dedicated to the legislation regarding the Social Insurance Institution, while there is constantly an extra emphasis given on the State Council’s jurisprudence. In particular, we thoroughly examine the concepts of medical and insurance disability, as they were first formed and evolved, their special features, the applicants’ obligations and the special requirements that they have to satisfy. Furthermore, burning concerns, such as the possibility of disabled retirees’ professional rehabilitation and the importance of public institutions’ decisions in providing lawful protection to those in interest and also the problems of the procedure in general are highlighted. Finally, there is an assessment of the system from a social perspective.

description: Context: We present the results of a set of observations of nine TeV detected BL Lac objects performed by the XRT and UVOT detectors on board the Swift satellite between March and December 2005. Aims: We are mainly interested in measuring the spectral parameters, and particularly the intrinsic curvature in the X-ray band. Methods: We perform X-ray spectral analysis of observed BL Lac TeV objects using either a log-parabolic or a simple power-law model . Results: We found that many of the objects in our sample do show significant spectral curvature, whereas those having the peak of the spectral energies distribution at energies lower than ~0.1 keV show power law spectra. In these cases, however, the statistics are generally low thus preventing a good estimate of the curvature. Simultaneous UVOT observations are important to verify how X-ray spectra can be extrapolated at lower frequencies and to search for multiple emission components. Conclusions: The results of our analysis are useful for the study of possible signatures of statistical acceleration processes predicting intrinsically curved spectra and for modelling the SED of BL Lacertae objects up to TeV energies where a corresponding curvature is likely to be present.

description: Τις τελευταίες δεκαετίες, η σταθερή ανάπτυξη του θαλάσσιου εμπορίου έχει ως αποτέλεσμα την ανάπτυξη των λιμένων και των τερματικών σταθμών τους. Η ναυτιλιακή αγορά συνεχώς εξελίσσεται. Από την πλευρά τους οι ναυτιλιακές εταιρίες σχηματίζουν κοινοπραξίες και συμμαχίες, ενώ οι λιμένες από τη δική τους, αναπτύσσουν τερματικούς σταθμούς παγκόσμιας εμβέλειας. Ένα αποτελεσματικό και βιώσιμο σύστημα λιμένων είναι ένας σημαντικός μεσολαβητής και ο οδηγός για την οικονομική ανάπτυξη. Ο σκοπός αυτής της εργασίας είναι η έρευνα και η ανάλυση της μεθοδολογίας αξιολόγησης της αποδοτικότητας των λιμένων και των τερματικών σταθμών και η μελέτη των παραγόντων που την επηρεάζουν. Επιδιώκεται η προσέγγιση του Οργανισμού Λιμένος Θεσσαλονίκης, η έρευνα των διαδικασιών και των δραστηριοτήτων που αναπτύσσονται ξεχωριστά για τον τερματικό σταθμό του συμβατικού φορτίου και για τον σταθμό εμπορευματοκιβωτίων και, τέλος, η δημιουργία ενός συστήματος δεικτών για την μέτρηση της αποδοτικότητας των δύο τερματικών σταθμών. Συμπερασματικά, από τα ευρήματα της ανάλυσης αυτής, προκύπτει ότι το σύστημα δεικτών αποδοτικότητας του λιμένα μπορεί να επηρεάσει αποφάσεις που λαμβάνονται από τους διαχειριστικούς φορείς του λιμένα και τους φορείς χάραξης πολιτικής, καθώς παρέχει μια επισκόπηση της αποτελεσματικότητας των τερματικών σταθμών και εξετάζει λεπτομερώς τις πηγές αναποτελεσματικότητας.
description: In recent decades, the steady growth of seaborne trade has resulted to the development of ports and their terminals. The shipping market is constantly evolving. Τhe shipping companies make joint ventures and alliances, while the ports develop global terminal stations. An efficient and sustainable port system is an important mediator and a factor for economic development. The aim of this work is the research and analysis of the performance evaluation methodology of ports and terminals, and the study of the factors affecting it. For the Thessaloniki Port Authority, the investigation of processes and activities carried out separately for the terminal of conventional cargo and the container terminal and, finally, the creation of a system of indicators to measure the two terminals efficiency. In conclusion, the findings of this analysis show that the port performance indicator system can influence decisions taken by the management of the port operators and policy makers, as it provides an overview of the effectiveness of the terminals and thoroughly examines the inefficiency sources .
