description: We present an algebraic classification, based on the null alignment properties of the Weyl tensor, of the general Kundt class of spacetimes in arbitrary dimension for which the non-expanding, non-twisting, shear-free null direction \boldk is a (multiple) Weyl aligned null direction (WAND). No field equations are used, so that the results apply not only to Einstein's gravity and its direct extension to higher dimensions, but also to any metric theory of gravity which admits the Kundt spacetimes. By an explicit evaluation of the Weyl tensor in a natural null frame we demonstrate that all Kundt geometries are of type I(b) or more special, and we derive simple necessary and sufficient conditions under which \boldk becomes a double, triple or quadruple WAND. All possible algebraically special types, including the refinement to subtypes, are identified, namely II(a), II(b), II(c), II(d), III(a), III(b), N, O, II_i, III_i, D(a), D(b), D(c) and D(d). The corresponding conditions are surprisingly clear and expressed in an invariant geometric form. Some of them are always satisfied in four dimensions. To illustrate our classification scheme, we apply it to the most important subfamilies of the Kundt class, namely the pp-waves, the VSI spacetimes, and generalization of the Bertotti-Robinson, Nariai, and Plebanski-Hacyan direct-product spacetimes of any dimension.

description: We study the depletion-induced self-assembly of indented colloids. Using state-of-the-art Monte Carlo simulation techniques that treat the depletant particles explicitly, we demonstrate that colloids assemble by a lock-and-key mechanism, leading to colloidal polymerization. The morphology of the chains that are formed depends sensitively on the size of the colloidal indentation, with smaller values additionally permitting chain branching. In contrast to the case of spheres with attractive patches, Wertheim's thermodynamic perturbation theory fails to provide a fully quantitative description of the polymerization transition. We trace this failure to a neglect of packing effects and we introduce a modified theory that accounts better for the shape of the colloids, yielding improved agreement with simulation.

description: Η ερευνητική εργασία εξετάζει τη θέση και την αναδυόμενη συνθήκη του αστέγου στη σύγχρονη πόλη.

Αρχικά εξετάζεται θεωρητικά η έννοια του ‘Τρίτου Όρου’ , ως ένας εναλλακτικός τρόπος προσέγγισης της «διαφοράς» στην σύγχρονη ρευστή πραγματικότητα, η οποία χαρακτηρίζεται από πολυπλοκότητα σε όλα τα επίπεδα(οικονομικό, πολιτικό, κοινωνικό κλπ) και σε όλες τις κλίμακες από τις μικροπρακτικές μέχρι τις μεγάλες αφηγήσεις. Η έννοια του Τρίτου Όρου, αφορά σε μία «άλλη» προσέγγιση της πραγματικότητας, η οποία προσπαθεί να υπερβεί την κυρίαρχη διπολική λογική και να απαντήσει στα ζητήματα κοινωνικών και χωρικών διαχωρισμών και διακρίσεων, τοποθετώντας το «περιθώριο» και την ετερότητα στο κέντρο του προβληματισμού της.

Ερευνάται η έννοια της ταυτότητας, που αντιμετωπίζεται ως ένας διπολικός μηχανισμός κατασκευής διαχωριστικών αποκλεισμών και των χωρικών τους εκφάνσεων στην σύγχρονη πόλη, με την δημιουργία ενός «μέσα-εμείς» και ενός «έξω- αυτοί». Αν και η πόλη αποτελεί ένα ελεγκτικό πεδίο με την τάση να ομογενοποιεί, να κατατάσσει και να αποκλείει, μπορεί δυνητικά, λόγω της ετερογένειας και την πολυμορφίας που την χαρακτηρίζουν, να μετατραπεί σε πεδίο έκφρασης της «διαφοράς».

Κατανοώντας το περιθώριο ως μία κατασκευή και παρατηρώντας τις εξελίξεις στην σημερινή περίοδο της κρίσης, όπου μεσαία και χαμηλά στρώματα συμπιέζονται οικονομικά και κοινωνικά και  όπου η κρίση κατοικίας εντείνεται ως εγγενές στοιχείο του καπιταλιστικού συστήματος, διαπιστώνεται, ότι οι ευάλωτες ομάδες συνεχώς διευρύνονται και οι πιθανότητες απώλειας στέγης διαρκώς αυξάνονται.

Υπό αυτό το πρίσμα, εξετάζεται από την έρευνα το φαινόμενο του αστέγου, το οποίο αποτελεί ένα δυναμικό φαινόμενο που βασίζεται σε ένα φαύλο κύκλο αποκλεισμού και περιθωριοποίησης και αφορά πολύ περισσότερο κόσμο από την ορατή εκδοχή του.

Μελετώνται τα μέσα με τα οποία η πόλη και οι δημόσιοι χώροι της μετατρέπονται σε ένα ελεγκτικό περιβάλλον με  χώρους αποκλεισμού καθώς και οι τρόποι με τους οποίους οι άστεγοι προσαρμόζονται, χρησιμοποιούν και επανανοηματοδοτούν τους χώρους της πόλης, κάνοντας εμφανή τον ενεργό τους ρόλο στην διαμόρφωση της. Τέλος, διερευνάται το ζήτημα της ορατότητας στον δημόσιο χώρο, ως το μέσο για την ανάδειξη και την αποδοχή μειονοτικών ομάδων, όπως οι άστεγοι.

description: A scattering transform defines a locally translation invariant representation which is stable to time-warping deformations. It extends MFCC representations by computing modulation spectrum coefficients of multiple orders, through cascades of wavelet convolutions and modulus operators. Second-order scattering coefficients characterize transient phenomena such as attacks and amplitude modulation. A frequency transposition invariant representation is obtained by applying a scattering transform along log-frequency. State-the-of-art classification results are obtained for musical genre and phone classification on GTZAN and TIMIT databases, respectively.

description: Nanotechnology has revolutionized drug delivery in cancer treatment. In this study, novel efficient pH-responsive boron phenylalanine (BPA) targeted nanoparticles (NPs) based on ionic liquid modified chitosan have been introduced for selective mitoxantrone (MTO) delivery to the U87MG glioma cells. Urocanic acid (UA) and imidazolium (Im) based ionic liquids were used for structural modification simultaneously. The NPs were prepared by ionic gelation and fully characterized; the pH-responding and swelling index of NPs were studied carefully. The drug release was studied at a pH of 5.5 in comparison to the neutral state. Also, the cytotoxicity of loaded NPs was evaluated on U87MG glial cells, and cellular uptake was studied. The NPs were smaller than 250 nm, with a spherical pattern and acceptable uniformity with a zeta potential around +20 mV. The loading efficacy was about 85%, and most of the loaded MTO released at a pH of 5.5 after 48 h with a swelling-controlled mechanism. The NPs showed a relatively lower IC50 than the free MTO, and the BPA-targeted NPs have lower IC50 and better cellular uptake than non-targeted NPs in U87MG cells. More studies on this promising formula are on the way, and the results will be published soon.

description: Discrete particle simulation, a combined approach of computational fluid dynamics and discrete methods such as DEM (Discrete Element Method), DSMC (Direct Simulation Monte Carlo), SPH (Smoothed Particle Hydrodynamics), PIC (Particle-In-Cell), etc., is becoming a practical tool for exploring lab-scale gas-solid systems owing to the fast development of parallel computation. However, gas-solid coupling and the corresponding fluid flow solver remain immature. In this work, we propose a modified lattice Boltzmann approach to consider the effect of both the local solid volume fraction and the local relative velocity between particles and fluid, which is different from the traditional volume-averaged Navier-Stokes equations. A time-driven hard sphere algorithm is combined to simulate the motion of individual particles, in which particles interact with each other via hard-sphere collisions, the collision detection and motion of particles are performed at constant time intervals. The EMMS (energy minimization multi-scale) drag is coupled with the lattice Boltzmann based discrete particle simulation to improve the accuracy. Two typical fluidization processes, namely, a single bubble injection at incipient fluidization and particle clustering in a fast fluidized bed riser, are simulated with this approach, with the results showing a good agreement with published correlations and experimental data. The capability of the approach to capture more detailed and intrinsic characteristics of particle-fluid systems is demonstrated. The method can also be used straightforward with other solid phase solvers.

description: Repositories of images with semantic and emotion content descriptions are valuable tools in many areas such as Affective Computing and Human-Computer Interaction, but they are also important in the development of multimodal searchable online databases. Ever growing number of image documents available on the Internet continuously motivates research of better annotation models and more efficient retrieval methods which use mash-up of available data on semantics, scenes, objects, events, context and emotion. Formal knowledge representation of such high-level semantics requires rich, explicit, human but also machine-processable information. To achieve these goals we present an online ontology-based image annotation tool WNtags and demonstrate its usefulness in knowledge representation and image retrieval using the International Affective Picture System database. The WNtags uses WordNet as image tagging glossary but considers Suggested Upper Merged Ontology as the preferred upper labeling formalism. The retrieval is performed using node distance metrics to establish semantic relatedness between a query and the collaboratively weighted tags describing high-level image semantics, after which the result is ranked according to the derived importance. We also elaborate plans to improve the WNtags to create a collaborative Web-based multimedia repository for research in human emotion and attention.

description: Indigenous and Tribal peoples’ right to free, prior and informed consent (FPIC) has transformative potential. Yet, there is a considerable gap between the theory and what happens in practice. Global actors supporting recognition of FPIC and effective prior consultation processes usually focus on normative standards and best practices. They concentrate much less on addressing the political challenges and opportunities that shape how these processes unfold. With funding from the Ford Foundation, we looked at the politics of FPIC in Latin America, analyzing how the power and interests of the key players–across governments, companies and indigenous peoples–can determine the fate of FPIC and consultation processes in practice. This research focused on Brazil, Colombia, and Peru, and provides practical options to address key political challenges in hopes of improving outcomes for indigenous and tribal peoples. In addition, we are partnering with Dejusticia and the multi-stakeholder Dialogue Group for Mining in Colombia (GDIAM) to explore further the political impediments to meaningful mining consultation processes in that country, and to field ideas for navigating these more effectively in the future.
Discrete Painleve equations and discrete KdV equation over finite fields

description: We investigate some of the discrete Painleve equations (dPII, qPI and qPII) and the discrete KdV equation over finite fields. The first part concerns the discrete Painleve equations. We review some of the ideas introduced in our previous papers and give some detailed discussions. We first show that they are well defined by extending the domain according to the theory of the space of initial conditions. We then extend them to the field of p-adic numbers and observe that they have a property that is called an `almost good reduction' of dynamical systems over finite fields. We can use this property, which can be interpreted as an arithmetic analogue of singularity confinement, to avoid the indeterminacy of the equations over finite fields and to obtain special solutions from those defined originally over fields of characteristic zero. In the second part we study the discrete KdV equation. We review the previous discussions and present a way to resolve the indeterminacy of the equation by treating it over a field of rational functions instead of the finite field itself. Explicit forms of soliton solutions and their periods over finite fields are obtained. Note: This is a review article on the recent developments in the theory of discrete integrable equations over finite fields based on arXiv:1201.5429, arXiv:1206.4456, arXiv:1209.0223. This article is published as the proceedings of the domestic conference "The breadth and depth of nonlinear discrete integrable systems" in RIMS, Kyoto University, Japan, on August 2012.

description: The relevance of the standing accretion shock instability (SASI) compared to neutrino-driven convection in three-dimensional (3D) supernova-core environments is still highly controversial. Studying a 27 Msun progenitor, we demonstrate, for the first time, that violent SASI activity can develop in 3D simulations with detailed neutrino transport despite the presence of convection. This result was obtained with the Prometheus-Vertex code with the same sophisticated neutrino treatment so far used only in 1D and 2D models. While buoyant plumes initially determine the nonradial mass motions in the postshock layer, bipolar shock sloshing with growing amplitude sets in during a phase of shock retraction and turns into a violent spiral mode whose growth is only quenched when the infall of the Si/SiO interface leads to strong shock expansion in response to a dramatic decrease of the mass accretion rate. In the phase of large-amplitude SASI sloshing and spiral motions, the postshock layer exhibits nonradial deformation dominated by the lowest-order spherical harmonics (l=1, m=0,-1,+1) in distinct contrast to the higher multipole structures associated with neutrino-driven convection. We find that the SASI amplitudes, shock asymmetry, and nonradial kinetic energy in 3D can exceed those of the corresponding 2D case during extended periods of the evolution. We also perform parametrized 3D simulations of a 25 Msun progenitor, using a simplified, gray neutrino transport scheme, an axis-free Yin-Yang grid, and different amplitudes of random seed perturbations. They confirm the importance of the SASI for another progenitor, its independence of the choice of spherical grid, and its preferred growth for fast accretion flows connected to small shock radii and compact proto-neutron stars as previously found in 2D setups.

Creators: name: Τσουκο Ρικελντα

description: Η διαφάνεια ως η ικανότητα του να βλέπεις αποτελεί μια έννοια που εξαρχής συνδέθηκε με το όραμα του μοντερνισμού για μια νέα, ανοιχτή κοινωνία. Η γυάλινη επιφάνεια έγινε το σύμβολο μιας αρχιτεκτονικής για περισσότερο φως, απεριόριστη θέα και απρόσκοπτη συνέχεια του εσωτερικού με τον εξωτερικό χώρο. Το 1955 o Colin Rowe και ο Robert Slutzky στο δοκίμιό τους “Transparency” εμπλουτίζουν αυτήν την έννοια με νέα νοήματα, όπως αλληλοδιείσδυση,  συγχρονικότητα, αμφιλεγόμενο, χωροχρόνος κ.ά, τα οποία στη σύγχρονη αρχιτεκτονική ορολογία εμφανίζονται σαν συνώνυμα. Σήμερα ο εμπλουτισμός της έννοιας συνεχίζεται. Βασισμένη στις απόψεις των Rowe και Slutzky, η Eve Blau προσθέτει ότι η διαφάνεια είναι μια έννοια που μπορεί να κατέχει μια σειρά αντιφάσεων οι οποίες ανοίγουν το έργο σε μια αόριστη αισθητική εμπειρία και ενισχύουν την χωρική εμπειρία.
Η παρούσα ερευνητική εργασία εστιάζει στη διερεύνηση της έννοιας της διαφάνειας σήμερα μέσα από το έργο των SANAA. Η εργασία δομείται σε δύο κεφάλαια. Στο πρώτο κεφάλαιο αναλύουμε την διάκριση της διαφάνειας σε Κυριολεκτική και Φαινομενική- μέσα από αναφορές σε  επιλεγμένα καλλιτεχνικά και αρχιτεκτονικά παραδείγματα. Στο δεύτερο κεφάλαιο εξετάζουμε τις «εκδοχές» της διαφάνειας στην αρχιτεκτονική των SANAA και εντοπίζουμε συσχετισμούς με το Μοντέρνο Κίνημα. Πιο εκτεταμένα επικεντρωνόμαστε στο Μουσείο Σύγχρονης Τέχνης για τον 21ο αιώνα στο οποίο αυτές οι «εκδοχές» συνωθούνται. Τελικά αναλύουμε το πως η έννοια της διαφάνειας συνδέεται με την παραγωγή της «ατμόσφαιρας», όπως οι αρχιτέκτονες την ορίζουν, και πώς ο τρόπος χρήσης του γυαλιού συμβάλλει, πέρα από τις αντιληπτικές συνδέσεις μεταξύ των χώρων, στην ενίσχυση αυτής.

description: We report some new applications of functional complex networks on acoustic emission waveforms from frictional interfaces. Our results show that laboratory faults undergo a sequence of generic phases as well as strengthening, weakening or fast-slip and slow-slip leading to healing. Also, using functional networks, we extend the dissipated energy due to acoustic emission signals in terms of short-term and long-term features of events. We show that the transition from regular to slow ruptures can have an additional production from the critical rupture class similar to the direct observations of this phenomenon in the transparent samples. Furthermore, we demonstrate detailed sub-micron evolution of the interface due to the short-term evolution of rupture tip, which is represented by phenomenological description of the modularity rates. In addition, we found nucleation phase of each single event for most amplified events follows a nearly constant time scale, corresponding to initial strengthening of interfaces.

description: We study the dynamics of electroweak bubbles in the scenario of a strong first order inverse electroweak phase transition at the TeV scale involving the global structure of the nonlinear sigma field in the littlest Higgs model with T parity. Employing the one-loop order finite temperature effective potential, we find that the pressure in the symmetric phase i.e., inside the bubble is always greater than that in the asymmetric phase i.e., outside the bubble, so that the bubbles are expanding. By calculating the fluid velocities in the two phases we arrive at the condition of a supersonic deflagrated motion of the bubble walls. We then discuss the generation of gravitational waves from the collisions of such bubbles as well as from the turbulence of the plasma.

description: The recent Planck results and future releases on the horizon present a key opportunity to address a fundamental question in inflationary cosmology of whether primordial density perturbations have a quantum or thermal origin, i.e. whether particle production may have significant effects during inflation. Warm inflation provides a natural arena to address this issue, with interactions between the scalar inflaton and other degrees of freedom leading to dissipative entropy production and associated thermal fluctuations. In this context, we present relations between CMB observables that can be directly tested against observational data. In particular, we show that the presence of a thermal bath warmer than the Hubble scale during inflation decreases the tensor-to-scalar ratio with respect to the conventional prediction in supercooled inflation, yielding $r< 8|n_t|$, where $n_t$ is the tensor spectral index. Focusing on supersymmetric models at low temperatures, we determine consistency relations between the observables characterizing the spectrum of adiabatic scalar and tensor modes, both for generic potentials and particular canonical examples, and which we compare with the WMAP and Planck results. Finally, we include the possibility of producing the observed baryon asymmetry during inflation through dissipative effects, thereby generating baryon isocurvature modes that can be easily accommodated by the Planck data.

description: AX J1754.2-2754, 1RXS J171824.2-402934 and 1RXH J173523.7-354013 are three persistent neutron star low-mass X-ray binaries that display a 2--10 keV accretion luminosity Lx of only (1-10)x1E34 erg s-1 (i.e., only ~0.005-0.05 % of the Eddington limit). The phenomenology of accreting neutron stars which accrete at such low accretion rates is not yet well known and the reason why they have such low accretion rates is also not clear. Therefore, we have obtained XMM-Newton data of these three sources and here we report our analysis of the high-quality X-ray spectra we have obtained for them. We find that AX J1754.2-2754 has Lx~1E35 erg s-1, while the other two have X-ray luminosities about an order of magnitude lower. However, all sources have a similar, relatively soft, spectrum with a photon index of 2.3-2.5, when the spectrum is fitted with an absorbed power-law model. This model fits the data of AX J1754.2-2754 adequately, but it cannot fit the data obtained for 1RXS J171824.2-402934 and 1RXH J173523.7-354013. For those sources a clear soft thermal component is needed to fit their spectra. This soft component contributes 40% - 50% to the 0.5-10 keV flux of the sources. When including this additional spectral component, the power-law photon indices are significantly lower. It can be excluded that a similar component with similar contributions to the 2-10 keV X-ray flux is present for AX J1754.2-2754, indicating that the soft spectrum of this source is mostly due to the fact that the power-law component itself is not hard. We note that we cannot excluded that weaker soft component is present in the spectrum of this source which only contributes up to ~25% to the 0.5-10 keV X-ray flux. We discuss our results in the context of what is known of accreting neutron stars at very low accretion rate.

description: The Nigerian National Petroleum Corporation’s (NNPC) persistent governance challenges have both hampered Nigeria’s oil sector development and deprived the country of public resources. The oil, climate, and COVID-19 crises and the ramp-up of the low-carbon transition exacerbate this reality, with the national oil company (NOC) delivering sub-optimal returns to its stakeholders. Other NOCs have taken meaningful steps to become players in the low-carbon energy transition domestically or in­ternationally—for example, Sau­di Arabia’s Saudi Aramco, Norway’s Equinor, Brazil’s Petrobras, Malaysia’s Petronas, and Algeria’s Sonatrach. These NOCs can serve as sources of inspiration for NNPC. These five NOCs have also undergone reforms of various aspects of their corporate governance. Even if not always sufficient, these reforms position them to be players of the energy transition. The current crisis provides a unique opportunity and political momentum for the Nigerian government and legislature to reconsider NNPC’s role in the context of the energy transition and implement profound reform of the company. While it is an incredible policy and political challenge, other NOCs are showing the way, and policy guidance is already out there to guide countries and companies.

description: The non-stationary dynamics of a bouncing ball, comprising of both periodic as well as chaotic behavior, is studied through wavelet transform. The multi-scale characterization of the time series displays clear signature of self-similarity, complex scaling behavior and periodicity. Self-similar behavior is quantified by the generalized Hurst exponent, obtained through both wavelet based multi-fractal detrended fluctuation analysis and Fourier methods. The scale dependent variable window size of the wavelets aptly captures both the transients and non-stationary periodic behavior, including the phase synchronization of different modes. The optimal time-frequency localization of the continuous Morlet wavelet is found to delineate the scales corresponding to neutral turbulence, viscous dissipation regions and different time varying periodic modulations.

description: Motivated by experiments on splitting one-dimensional quasi-condensates, we study the statistics of the work done by a quantum quench in a bosonic system. We discuss the general features of the probability distribution of the work and focus on its behaviour at the lowest energy threshold, which develops an edge singularity. A formal connection between this probability distribution and the critical Casimir effect in thin classical films shows that certain features of the edge singularity are universal as the post-quench gap tends to zero. Our results are quantitatively illustrated by an exact calculation for non-interacting bosonic systems. The effects of finite system size, dimensionality, and non-zero initial temperature are discussed in detail.

description: Hadronic matrix elements of proton decay are essential ingredients to bridge the grand unification theory to low energy observables like proton lifetime. In this paper we non-perturbatively calculate the matrix elements, relevant for the process of a nucleon decaying into a pseudoscalar meson and an anti-lepton through generic baryon number violating four-fermi operators. Lattice QCD with 2+1 flavor dynamical domain-wall fermions with the {\it direct} method, which is direct measurement of matrix element from three-point function without chiral perturbation theory, are used for this study to have good control over the lattice discretization error, operator renormalization, and chiral extrapolation. The relevant form factors for possible transition process from an initial proton or neutron to a final pion or kaon induced by all types of three quark operators are obtained through three-point functions of (nucleon)-(three-quark operator)-(meson) with physical kinematics. In this study all the relevant systematic uncertainties of the form factors are taken into account for the first time, and the total error is found to be the range 30%-40% for $π$ and 20%-40% for $K$ final states.

description:       Η παρούσα εργασία ασχολείται με την μελέτη του σταδίου της εγκατάλειψης των κτηρίων, που μετεωρίζεται μεταξύ «έμβιου» κτηρίου (κτήριο με χρήση) και ερειπίου. Πιο συγκεκριμένα, αντικείμενο της εργασίας είναι η αυτονόμηση της εγκατάλειψης, ως περιόδου ύπαρξης των κτηρίων με συγκεκριμένα χαρακτηριστικά, όπου ως πρωταρχική τους αρετή οφείλει να συνεχίσει και να τροφοδοτείται.
      Σκοπός της είναι η ταύτιση του σταδίου της εγκατάλειψης ενός κτίσματος με τον μεταφορικό θάνατο του ή έστω με την αρχή του, καθώς και η ερμηνεία των επιπτώσεων, που φέρει στον άνθρωπο η επίσκεψη σε αυτόν, έτσι ώστε να διερευνηθεί κατά πόσον μπορεί να αποτελέσει αξία αυτόνομη στην συνείδησή μας. Η εγκατάλειψη εμφανίζεται ως ένας ανεστραμμένος κόσμος, στον οποίο λαμβάνει χώρα η απουσία, η οποία μεταμορφώνεται στην μοναδική πραγματική παρουσία για τον επισκέπτη του και μέσα σε αυτόν διερευνάται το Είναι του ανθρώπου. Στο εγκαταλελειμμένο κτίσμα γεννάται μία ιδιαίτερη ατμόσφαιρα, η οποία περιβάλλει τις αισθήσεις, τη σκέψη και τη φαντασία του ανθρώπου κατά την επαφή του με αυτό. Εντός του έρχεται αντιμέτωπος με τη διάσταση του άχρονου, όχι μιας εκτός χρόνου διάστασης, αλλά μια συγχρονικότητα, δηλαδή μία ιδιαίτερη έκφραση της ίδιας της χρονικότητας. Μέσα από αυτό το προσωπικό του βίωμα, ψηλαφεί το Είναι του σε σχέση με τον περιβάλλοντα κόσμο, μέσω του φαινομένου της συνεχούς επαγρύπνησης, που αναδύεται από την αποκάλυψη του είναι – προς – το – θάνατο.

description: The random beamforming (RBF) scheme, jointly applied with multi-user diversity based scheduling, is able to achieve virtually interference-free downlink transmissions with only partial channel state information (CSI) available at the transmitter. However, the impact of receive spatial diversity on the rate performance of RBF is not fully characterized yet even in a single-cell setup. In this paper, we study a multi-cell multiple-input multiple-output (MIMO) broadcast system with RBF applied at each base station (BS) and either the minimum-mean-square-error (MMSE), matched filter (MF), or antenna selection (AS) based spatial receiver employed at each mobile terminal. We investigate the effect of different spatial diversity receivers on the achievable sum-rate of multi-cell RBF systems subject to both the intra- and inter-cell interferences. We first derive closed-form expressions for the distributions of the receiver signal-to-interference-plus-noise ratio (SINR) with different spatial diversity techniques, based on which we compare their rate performances at finite signal-to-noise ratios (SNRs). We then investigate the asymptotically high-SNR regime and for a tractable analysis assume that the number of users in each cell scales in a certain order with the per-cell SNR as SNR goes to infinity. Under this setup, we characterize the degrees of freedom (DoF) region for multi-cell RBF systems with different types of spatial receivers, which consists of all the achievable DoF tuples for the individual sum-rate of all the cells. The DoF region analysis provides a succinct characterization of the interplays among the receive spatial diversity, multiuser diversity, spatial multiplexing gain, inter-/intra-cell interferences, and BSs' collaborative transmission.

description: Αντικείμενο της  παρούσας ερευνητικής εργασίας είναι η διερεύνηση των χαρακτηριστικών των  παραδοσιακών οικισμών των Δωδεκανήσων, στη δομή και τη μορφή των οποίων διατηρούνται τα πρωτότυπα και αυθεντικά στοιχεία της αρχιτεκτονικής παράδοσης που αναπτύχθηκε στον συγκεκριμένο τόπο. Αρχικά γίνεται αναφορά στον ορισμό και την προέλευση του όρου «παραδοσιακός οικισμός» και παρατίθενται τα εργαλεία και οι νομικές διατάξεις προστασίας των παραδοσιακών συνόλων.  Στην συνέχεια επιχειρείται η ταξινόμηση των τύπων των κατοικιών των Δωδεκανήσων σε κατηγορίες ανάλογα με τα κτιριακά τους χαρακτηριστικά και τις θέσεις στις οποίες έχουν καταγραφεί. Από τη μελέτη προκύπτουν έξι  τυπολογίες που έχουν αναπτυχθεί ανάλογα με τις ιστορικές συγκυρίες κάθε εποχής. Εξετάζεται η σχέση της κατοικίας με το δημόσιο χώρο μέσα από χώρους μετάβασης και οι διαφορές της σχέσης ιδιωτικού-δημόσιου όπως αυτές εμφανίζονται σε κάθε τυπολογία. Στην επόμενη ενότητα μελετάται ο τρόπος με τον οποίο συναντώνται  κάποιες από τις  τυπολογίες αυτές  στον οικισμό της Λίνδου και οι μεταλλαγές που έχουν υποστεί διαχρονικά. Για την πληρέστερη μελέτη του οικισμού, εξετάζεται η ένταξη των κατοικιών  ως κυττάρων στο σύνολο του χώρου, δηλαδή στον πολεοδομικό ιστό του οικισμού. Διερευνώνται στοιχεία όπως τα δίκτυα, οι χρήσεις κλπ. ώστε να εξετασθεί ο τρόπος διάρθρωσης των κατοικιών στο συνεκτικό πυρήνα του ιστορικού συνόλου. Τέλος μελετώνται τα προβλήματα καθώς και τα στοιχεία αλλοίωσης του μορφολογικού και αισθητικού χαρακτήρα του οικισμού εξ αιτίας κυρίως της έντονης τουριστικής δραστηριότητας του νησιού της Ρόδου.
