description: This is the third paper in a series. In part I we developed a deformation theory of objects in homotopy and derived categories of DG categories. Here we show how this theory can be used to study deformations of objects in homotopy and derived categories of abelian categories. Then we consider examples from (noncommutative) algebraic geometry. In particular, we study noncommutative Grassmanians that are true noncommutative moduli spaces of structure sheaves of projective subspaces in projective spaces.

description: Το συνεχές παραγωγικό αστικό τοπίο αποτελεί μια περιβαλλοντική έννοια άμεσα συνδεδεμένη με το τοπίο που εισήχθη από τον αρχιτέκτονα Andre Vilijoen και τους συνεργάτες του το 2004. Ως εκ τούτου, ο στόχος της παρούσας εργασίας εντοπίζεται στην επανεξέταση της έννοιας του Συνεχούς Παραγωγικού Αστικού Τοπίου ως ένα νέο παράδειγμα το οποίο αναπτύσσεται εντός του πλαισίου του σχεδιασμού των Πράσινων Υποδομών, πάντοτε άμεσα συνδεδεμένο με το σύγχρονο αστικό τοπίο και την έννοια του Παραγωγικού Τοπίου. Μέσω της άνωθεν διαδικασίας εξήχθησαν βασικά συμπεράσματα που σχετίζονται με τις θεμελιώδεις έννοιες της αειφορίας και του τοπίου, και επιπλέον αναπτύχθηκε μια πρόταση για τις Πράσινες Υποδομές στο επίπεδο του αστικού περιβάλλοντος, η οποία αφορά το Αστικό Τοπίο στην πόλη Νις της Σερβίας. Στο πρώτο μέρος της διατριβής η έννοια του Συνεχούς Παραγωγικού Αστικού Τοπίου μελετάται σε συνάρτηση με την αειφορική ανάπτυξη: προσεγγίζεται από κοινωνικοοικονομική και από περιβαλλοντική άποψη, ενώ επιπλέον τοποθετείται εντός ενός αστικής κλίμακας τοπίου: Στο δεύτερο μέρος της διατριβής αναπτύσσεται μια πρόταση για την εφαρμογή των αρχών των Συνεχών Παραγωγικών Αστικών Τοπίων στην πόλη Νις. Στόχος της σχεδιαστικής πρότασης είναι η δημιουργία ενός παραδείγματος του Συνεχούς Παραγωγικού Αστικού Τοπίου στον πυρήνα της πόλης. Η νέα πράσινη υποδομή θα συνδέσει σημαντικά σημεία της πόλης καθώς διατρέχει τον αστικό ιστό: το Φρούριο της Νις, τον ποταμό Νισάβα και την εκκλησία Σαμπόρνα.
description: Continuous productive urban landscape is a landscape and environmental concept created by an architect Andre Viljoen and his colleagues in 2004. Therefore, the goal of this thesis is to reconsider the concept of Continuous Productive Urban Landscapes as an new paradigm developed within the planning to of Green Infrastructure, but in relation to the contemporary Urban Landscape and the concept of Productive Landscape. This made possible for giving basic conclusions concerned with the two basic concept sustainability and landscapes, but also for the proposal for the Green Infrastructure on an level of urban environment, implemented in the Urban Landscape of Nis, Serbia. In the first part of the thesis the concept of Continuous Productive Urban Landscapes has been placed in terms of sustainability: socio- economical and environmental terms, but also placed within an urban-scale landscape: In the second part of the mater thesis, proposal was made for the implementation of Continuous Productive Urban Landscapes in the city of Nis. The aim of the design proposal is to create an example of Continuous Productive urban Landscapes in the city core. The new green infrastructure will connect important places of the city: Fortress of Niš, Nišava river and Saborna church while passing through urban tissue.

Analysis of the eclipsing binaries in the LMC discovered by OGLE: Period distribution and frequency of the short-period binaries

description: We review the results of our analysis of the OGLE LMC eclipsing binaries (Mazeh, Tamuz & North 2006), using EBAS -- Eclipsing Binary Automated Solver, an automated algorithm to fit lightcurves of eclipsing binaries (Tamuz, Mazeh & North 2006). After being corrected for observational selection effects, the set of detected eclipsing binaries yielded the period distribution and the frequency of all LMC short-period binaries, and not just the eclipsing systems. Somewhat surprisingly, the period distribution is consistent with a flat distribution in log P between 2 and 10 days. The total number of binaries with periods shorter than 10 days in the LMC was estimated to be about 5000. This figure led us to suggest that (0.7 +- 0.4)% of the main-sequence A- and B-type stars are found in binaries with periods shorter than 10 days. This frequency is substantially smaller than the fraction of binaries found by small Galactic radial-velocity surveys of B stars.

Three essays on North-South trade, growth, and development
Creators: name: Chayun, Tantivasadakarn
Publisher: name: University of British Columbia
Year: 2009

description: This thesis focuses on three issues pertaining to growth, development, and trade between developed and developing countries. The first essay develops an endogenous growth model that incorporates Engel’s law into the preferences. The model shows that the initial distribution of income is crucial to the outcome. A closed-economy country where most of its population is poor experiences a low rate of innovation. Income transfers from the rich to the poor can increase the effective labour supply, thereby enhancing the rate of innovation. Under free trade, only the rich benefit from trade. The poor are indifferent unless they already can afford to consume the minimum requirement of food before trade or the minimum requirement becomes affordable after trade by cheaper imported food. The initial distribution of income influences the trade patterns. Moreover, income redistribution in a free trade environment also increases the growth rate. The second essay extends the first one by assuming that the marginal product of labour of the food sector is decreasing. It shows that an increase in population may decrease the growth rate if the initial population is large relative to the productivity of the food sector. Moreover, an increase in one country’s population may reduce that country’s production share of the world’s innovation and increase its dependency on imported technology. The last essay analyzes the welfare impact of minimum-export requirements (MERs) imposed on foreign direct investments. This essay shows that MERs can be Pareto improving measures to both the source and the host countries. When offshore plants are used by parent firms to compete with domestic firms in the source country, MERs can improve the host country’s welfare by inducing the total sales in the source country to rise, thereby reducing the distortion generated by imperfect competition. The MERs can simultaneously improve the welfare of the host country by shifting profits of the foreign firms toward the local firms. If the local firms are absent, the host’s welfare may still be improved if sufficient profits from foreign operations are retained in the host country.

description: Tracing the history of chemical evolution of the Milky Way requires the determination of chemical abundances in a large assortment of stars with accurate stellar parameters. Nonetheless, the accuracy achieved in the derived astrophysical parameters is still insufficient, mainly because of the paucity of adequate calibrators, particularly in the metal-poor regime ([Fe/H] < -1.0). At present, the prime stellar calibration sample is that of the Gaia benchmark stars. Most of these stars have effective temperature constrained by measurements of their bolometric fluxes and angular diameters. However, only seven of them are metal-poor. To increase this number, we introduce the “Titans metal-poor reference stars”: stars with accurate model-dependent parameters that are "descendants" of the Gaia benchmarks.

The spin history of the neutron star in this system exhibits torque reversals lasting ~1 yr. The newly discovered super-orbital period has remained stable over the 9-yr span, making 2S 0114+650 the fourth known system to exhibit stable super-orbital modulation. We compare its super-orbital period evolution with those of the other three such systems.

description: We present a hybrid equation of state (EoS) for dense matter that satisfies phenomenological constraints from modern compact star (CS) observations which indicate high maximum masses (M = 2 M_sun) and large radii (R> 12 km). The corresponding isospin symmetric EoS is consistent with flow data analyses of heavy-ion collisions and a deconfinement transition at approx. 0.55 fm^{-3}. The quark matter phase is described by a 3-flavor Nambu--Jona-Lasinio model that accounts for scalar diquark condensation and vector meson interactions while the nuclear matter phase is obtained within the Dirac-Brueckner-Hartree-Fock (DBHF) approach using the Bonn-A potential. We demonstrate that both pure neutron stars and neutron stars with quark matter cores (QCSs) are consistent with modern CS observations. Hybrid star configurations with a CFL quark core are unstable.

Εξετάσαμε την νομοθεσία που διέπει το συγκεκριμένο ζήτημα. Στη συνέχεια παρουσιάσαμε αναλυτικά τα χαρακτηριστικά του χώρου της φυλακής και κατά πόσο επηρεάζουν την ψυχολογία των κρατουμένων. Επιπλέον, εξετάσαμε παράγοντες που εμφανίζονται μέσα στη φυλακή, όπως ο ιδρυματισμός, καθώς και παράγοντες που εμφανίζονται μετά την αποφυλάκιση, όπως η ανεργία, που εμποδίζουν την ομαλή επανένταξη. Ακόμη εκθέσαμε τα χαρακτηριστικά ορισμένων κατηγοριών κρατουμένων και τη διαδικασία επανένταξής τους. Ένας ακόμη σκοπός της μελέτης αυτής ήταν η εξέταση θεσμών όπως η χορήγηση αδειών, η εκπαίδευση των κρατουμένων, η εργασία των κρατουμένων κατά τη διάρκεια της κράτησης και η συμβολή της συμβουλευτικής ψυχολογίας και της θρησκείας, που βοηθούν στην επανένταξη.
description: The aim of the thesis was the study of the main parameters governing the issue of reintegration of prisoners into society. We analyzed the concept "social reintegration ". We examined the legislation governing this issue. Furthermore, we analyzed the features of the prison and how they affect the psychology of prisoners. We also examined factors occurring within the prison , such as institutionalization , and factors that appear after the release , such as unemployment , that prevent the smooth reintegration. Furthermore we presented the features of some categories of prisoners and the process of their reintegration . Another aim of this study was to examine institutions such as licensing , educational training of prisoners, the work of prisoners during detention and the contribution of counseling psychology and religion , that help the reintegration .

description: The H2020 project FarFish aims to provide knowledge, tools and methods to support responsible, sustainable and profitable EU fisheries outside European waters. To achieve this, one of the implementation tools is the Stakeholder Hub, a multi-level and multi-stakeholder network integrated by scientists, policymakers, resource users, NGOs and other stakeholders aimed to improve fisheries management competences throughout their participation. The Stakeholder Hub is a responsive and flexible platform that adopts the form of a regional working group for the six case studies involved into the project, but adopting the form of a high-level European platform, or even an international forum for cross-cutting issues. This Intermediate report provides a summary on the Stakeholder Hub implementation in the first half of the project. It highlights lessons learnt and improvement areas for the second part of the project.

description: The performance of a two-phase Ar avalanche detector with CsI photocathode was studied, with regard to potential application in coherent neutrino-nucleus scattering and dark matter search experiments. The detector comprised a 1 cm thick liquid Ar layer and a triple-GEM multiplier operated in the saturated vapor above the liquid phase; the CsI photocathode was deposited on the first GEM. Successful detection of both primary scintillation and ionization signals, produced by beta-particles in liquid Ar, has for the first time been demonstrated in the two-phase avalanche mode.

description: Στην παρούσα διπλωματική εργασία προτείνονται μέθοδοι για αναγνώριση κίνησης και ταυτότητας ανθρώπου, οι οποίες εφαρμόζονται σε δεδομένα που προέρχονται από καταγραφή κίνησης. Η προσέγγιση που ακολουθείται στην πρώτη μέθοδο, απορρέει από την υπόθεση ότι, αν δύο ακολουθίες κίνησης περιγράφουν όμοιες δραστηριότητες, τότε, διαδοχικά πλαίσια της μιας ακολουθίας αναμένεται να εμφανίζουν ομοιότητα με διαδοχικά πλαίσια της άλλης. Η προτεινόμενη μέθοδος κατασκευάζει σε πρώτο στάδιο έναν πίνακα αντιστοιχίσεων, ο οποίος αναπαριστά την ομοιότητα μεταξύ των πλαισίων δύο ακολουθιών, ενώ στη συνέχεια, και με βάση τη δομή του πίνακα αυτού, υπολογίζεται ένας βαθμός ομοιότητας μεταξύ των ακολουθιών. Η δεύτερη μέθοδος που αναπτύχθηκε αποτελεί μια προσέγγιση bag of words, στην οποία κάθε ακολουθία κίνησης αναπαριστάται από ένα ιστόγραμμα. Τα ιστογράμματα υπολογίζονται από τις ακολουθίες με βάση τη συχνότητα εμφάνισης ενός συνόλου από χαρακτηριστικές πόζες. Η μέθοδος αυτή συνδυάζεται με την εφαρμογή μείωσης διάστασης στα δεδομένα κίνησης, μέσω της τεχνικής Locality Preserving Projections (LPP), ως στάδιο προ-επεξεργασίας.
description: In this thesis, we propose methods for activity and person recognition, applied on motion capture data. The approach of the first method is driven from the assumption that, if two motion sequences correspond to similar activities, then, consecutive frames (poses) of one sequence are expected to be similar to consecutive frames of the other. The proposed method constructs a pose correspondence matrix to represent the similarity between poses and subsequently applies an intuitive method for estimating a similarity score between two motion capture sequences, based on the structure of the correspondence matrix. The second method is based on a bag of words model, where histograms are extracted from motion sequences, according to the frequency of occurrences of characteristic poses. This method is combined with the application of a dimensionality reduction method on the motion data, namely Locality Preserving Projections (LPP), as a pre-processing step.

Fermi surface and pseudogap in electron-doped cuprates

description: Spectral functions are evaluated numerically within the t-t'-J model as relevant for electron-doped cuprates. The Fermi surface develops from a pocket-like into a large one with doping. The corresponding pseudogap in the nodal direction is well resolved at low doping and vanishes at intermediate doping. Its presence is strongly temperature dependent and thus connected to longer-range antiferromagnetic correlations. Features including double effective band and optical conductivity are consistent with experiments on electron-doped cuprates without invoking the closing of the Mott-Hubbard gap.

description: Context:Ages derived from the low mass stars still contracting onto the main sequence often differ from ages derived from the high mass ones that have already evolved away from it. Aims:We investigate the general claim of disagreement between these two independent age determinations by presenting UBVRI photometry of the young galactic open clusters NGC 2232, NGC 2516, NGC 2547 and NGC 4755, spanning the age range ~10-150 Myr Methods: We derive reddenings, distances and nuclear ages by fitting ZAMS and isochrones to color-magnitudes and color-color diagrams. To derive contraction ages, we use four different pre-main sequence models, with an empirically calibrated color-temperature relation to match the Pleiades cluster sequence. Results: When using exclusively the V vs. V-I color-magnitude diagram and empirically calibrated isochrones, there is consistency between nuclear and contraction ages for the studied clusters. Although the contraction ages seem systematically underestimated, in none of cases they deviate by more than one standard deviation from the nuclear ages.

description: The quantum corrections to the frequencies of the $Γ$ point longitudinal optical (LO) and transverse optical (TO) phonon modes in carbon nanotubes are investigated theoretically. The frequency shift and broadening of the TO phonon mode strongly depend on the curvature effect due to a special electron-phonon coupling in carbon nanotubes, which is shown by the Fermi energy dependence of the frequency shift for different nanotube chiralities. It is also shown that the TO mode near the $Γ$ point decouples from electrons due to local gauge symmetry and that a phonon mixing between LO and TO modes is absent due to time-reversal symmetry. Some comparison between theory and experiment is presented.

description: I propose a reinterpretation of cosmic dark matter in which a rigid network of cosmic strings formed at the end of inflation. The cosmic strings fulfill three functions: At recombination they provide an accretion mechanism for virializing baryonic and warm dark matter into disks. These cosmic strings survive as configurations which thread spiral and elliptical galaxies leading to the observed flatness of rotation curves and the Tully-Fisher relation. We find a relationship between the rotational velocity of the galaxy and the string tension and discuss the testability of this model.

description: We consider a family of Markov maps on the unit interval, interpolating between the tent map and the Farey map. The latter map is not uniformly expanding. Each map being composed of two fractional linear transformations, the family generalizes many particular properties which for the case of the Farey map have been successfully exploited in number theory. We analyze the dynamics through the spectral analysis of generalized transfer operators.

description: Τα αγροδασικά τοπία αντιπροσωπεύουν παραδοσιακούς τρόπους ζωής ενώ ταυτόχρονα διαποτίζονται με πολιτισμικές, συμβολικές ή ακόμη και θρησκευτικές αξίες. Γι΄ αυτό το λόγο η προστασία και η διατήρηση τους είναι αναγκαία. Το «Κουρί» Αλμυρού αποτελεί ένα τέτοιο τοπίο με υψηλή περιβαλλοντική αξία η οποία έγκειται κυρίως στο γεγονός ότι είναι το μοναδικό στην Ευρώπη σε πεδινή έκταση. Η πρόταση αξιοποίησης και ανάπτυξης του «Κουρί» βασίζεται στον αειφορικό σχεδιασμό και διαχείριση του τοπίου της πολιτισμικής μιας κληρονομιάς. Η ιδέα σχεδιασμού στηρίζεται στη δημιουργία ενός φυσικού πάρκου και πραγματοποιείται σε δύο άξονες. Ο πρώτος άξονας αφορά την ανάπτυξη και προώθηση εναλλακτικών μορφών τουρισμού, περιβαλλοντικής εκπαίδευσης και ερμηνείας του τοπίου ενώ ο δεύτερος άξονας αφορά το σχεδιασμό της διαχείρισης του τοπίου. Με τους τρόπους αυτούς επιτυγχάνεται η προστασία και η ανάδειξη του ως πολιτισμικό τοπίο χαρακτηριστικό της συγκεκριμένης περιοχής.
description: Αgroforestry landscapes represent traditional lifestyles and at the same time they are imbued with cultural, symbolic and even religious value. That is why their protection and conservation is necessary. “Κouri” of Almyros is such a landscape with a high environmental value, which lies mainly in the fact that it is the olny one in Europe existing in a lowland area. The proposal for the utilization and development of “Κouri” is based on sustainable planning and management of the landscape of our cultural heritage. The concept is based on the creation of a natural park delivered in two axes. The first axis has to do with the development and promotion of alternative forms of tourism, environmental education and interpretation of landscape while the second axis concerns the planning of landscape management. In such a way its protection and enhancement as a cultural landscape, characteristic of the specific area, is ensured.

description: Persistence modules are algebraic constructs  that can be used to describe the shape of an object starting from a geometric representation of it. As shape descriptors, persistence modules are not complete, that is they may not distinguish non-equivalent shapes.
In this paper we show that one reason for this is that homomorphisms between persistence modules forget the geometric nature of the problem. Therefore we introduce geometric homomorphisms between persistence modules, and show that in some cases they perform better. A combinatorial structure, the $H_0$-tree, is shown to be an invariant for geometric isomorphism classes in the case of persistence modules obtained through the 0th persistent homology functor.

description: We present an analytic computation of the two-loop QCD corrections to $u\bar{d}\to W^+b\bar{b}$ for an on-shell $W$-boson using the leading colour and massless bottom quark approximations. We perform an integration-by-parts reduction of the unpolarised squared matrix element using finite field reconstruction techniques and identify an independent basis of special functions that allows an analytic subtraction of the infrared and ultraviolet poles. This basis is valid for all planar topologies for five-particle scattering with an off-shell leg.

description: The electromagnetic form factors of hadrons as measured both in the space like and time like domains provide fundamental information on the nucleon structure and internal dynamics. General expressions, including the lepton mass, for the spin averaged differential cross section for the annihilation reaction lepton antilepton to proton antiproton are given, as well as general formulae for the single and double spin asymmetries. The time reversed reaction would involve a kinematic factor. We also present general expressions for the helicity amplitudes for this reaction.

Subjects: ING-IND/15 Disegno e metodi dell'ingegneria industriale

description: The research activity focused on the study, design and evaluation of innovative human-machine interfaces based on virtual three-dimensional environments. 
It is based on the brain electrical activities recorded in real time through the electrical impulses emitted by the brain waves of the user. The achieved target is to identify and sort in real time the different brain states and adapt the interface and/or stimuli to the corresponding emotional state of the user. 
The setup of an experimental facility based on an innovative experimental methodology for “man in the loop" simulation was established. It allowed involving during pilot training in virtually simulated flights, both pilot and flight examiner, in order to compare the subjective evaluations of this latter to the objective measurements of the brain activity of the pilot. This was done recording all the relevant information versus a time-line. 
Different combinations of emotional intensities obtained, led to an evaluation of the current situational awareness of the user. These results have a great implication in the current training methodology of the pilots, and its use could be extended as a tool that can improve the evaluation of a pilot/crew performance in interacting with the aircraft when performing tasks and procedures, especially in critical situations.
This research also resulted in the design of an interface that adapts the control of the machine to the situation awareness of the user. The new concept worked on, aimed at improving the efficiency between a user and the interface, and gaining capacity by reducing the user’s workload and hence improving the system overall safety.
This innovative research combining emotions measured through electroencephalography resulted in a human-machine interface that would have three aeronautical related applications:
•	An evaluation tool during the pilot training;
•	An input for cockpit environment;
•	An adaptation tool of the cockpit automation.

description: The topic of this thesis fo cus on the preliminary design and the p erformance analysis of a multirotor platform. A multirotor is an electrically p owered Vertical Take Off (VTOL) machine with more than two rotors that lift and control the platform. Multirotor are agile, compact and robust, making them ideally suited for b oth indo or and outdo or application especially to carry-on several sensors like electro optical multisp ectral sensor or gas sensor. The main disadvantage is the limited endurance due to heavy Li-Po batteries and high disk loading through the use of different small prop ellers. At the same time, the design of the multirotor do es not follow any engineering principle but it follow the ideas of amateurs’ builder. An adaptation of the classic airplane design theory for the preliminary design is implemented to fill the gap and detailed study of the endurance is p erformed to define the right way to make this kind of VTOL platforms.

description: Dynamical response of nanomechanical cantilever structures immersed in a viscous fluid is important to in vitro single-molecule force spectroscopy, biomolecular recognition of disease-specific proteins, and the detection of microscopic dynamics of proteins. Here we study the stochastic response of biofunctionalized nanomechanical cantilevers beam in a viscous fluid. Using the fluctuation-dissipation theorem we derive an exact expression for the spectral density of the displacement and a linear approximation for the resonance frequency shift. We find that in a viscous solution the frequency shift of the nanoscale cantilever is determined by surface stress generated by biomolecular interaction with negligible contributions from mass loading.

description: This thesis deals with the analytic study of dynamics of Multi--Rotor Unmanned Aerial Vehicles. It is conceived to give a set of mathematical instruments apt to the theoretical study and design of these flying machines. The entire work is organized in analogy with  classical academic texts about airplane flight dynamics.
First, the non--linear equations of motion are defined and all the external actions are modeled, with particular attention to rotors aerodynamics. All the equations are provided in a form, and with personal expedients, to be directly exploitable in a simulation environment. This has requited an answer to questions like the trim of such mathematical systems. All the treatment is developed aiming at the description of different multi--rotor configurations.
Then, the linearized equations of motion are derived. The computation of the stability and control derivatives of the linear model is carried out. The study of static and dynamic stability characteristics is, thus, addressed, showing the influence of the various geometric and aerodynamic parameters of the machine and in particular of the rotors.
All the theoretic results are finally utilized in two interesting cases. 
One concerns the design of control systems for attitude stabilization. The linear model permits the tuning of linear controllers gains and the non--linear model allows the numerical testing.
The other case is the study of the performances of an innovative configuration of quad--rotor aircraft. With the non--linear model the feasibility of maneuvers impossible for a traditional quad--rotor is assessed. The linear model is applied to the controllability analysis of such an aircraft in case of actuator block.

Με την έννοια γραμματική αναφέρονται τα ακόλουθα τέσσερα χαρακτηριστικά: Α) Οι ιεραρχικές αναλύσεις των σκηνών σε αντικείμενα, τμήματα και πίξελ με τελικούς και μη τελικούς κόμβους, όπως επίσης και η σύνδεση ανάμεσα στους κόμβους με χωρικές και συναρτησιακές σχέσεις. Β) Η γραφική αναπαράσταση σε ένα γράφημα Και-Ή (And-Or) στο οποίο κάθε κόμβος And μπορεί να διαχωριστεί σε διάφορα στοιχεία, ενώ κάθε κόμβος Or αναπαριστά διαφορετικά υποστοιχεία. Γ) Ο ορισμός ενός στοχαστικού μοντέλου στην αναπαράσταση γραφήματος And-Or που υπολογίζει τη συχνότητα των αντικειμένων και των τμημάτων και τη μεταξύ τους συσχέτιση. Δ) Η συμπλήρωση ανάμεσα σε σύμβολα και πρωτογενή σήματα με μια σειρά γραμματικών λεξικών, τα οποία οργανώνονται για το σχηματισμό γραφημάτων. Στο λεξικό υπάρχει ένα σύνολο αρχέτυπων εικόνων που συνδέονται με άλλες εικόνες. Ο συνδυασμός των αρχέτυπων εικόνων μπορεί να οδηγήσει στο σχηματισμό γραφικών τμημάτων και αντικειμένων.

description: In this work the stochastic framework of image grammar is presented. The main characteristics of image grammar are the decomposition of scenes in objects, pixels and primitives, the representation of And-Or graphs and its components and the definition of a probabilistic model on And-Or graphs. The gap between symbols and signals is covered with a number of visual dictionaries which are organized by a grammar to form graphs. The primitives are composed with open bonds with other primitives to generate graph structures for objects and parts. The objective is the primal sketch graph through top-down procedures which will produce the input image. The contents of an input image are interpreted through a parse graph which contains a tree and relations and contexts as horizontal links. The And-Οr graph encloses the whole image grammar and contains all the valid parse graphs which produce a combinational number of configurations.
