Data management

description: During the SEADDA COST action, it was identified that many countries lack the capacity and expertise to create, manage, and share data according to the FAIR principles. SND (https://snd.gu.se/en), member of that action, had the same experience when looking at the Swedish universities. In 2018, SND’s mission was broadened to be a national research infrastructure for all research areas, resulting in the initiation of the SND network (https://snd.gu.se/en/ about-us/snd-network). This happened due to the realization that without a massive increase of SND staff, the universities would have to do most of the data management/curation themselves, so research data could be shared in accordance with the FAIR principles (e.g., via SND’s research data catalogue: https://snd.gu.se/en/catalogue/search), but also to make sure that each university had the capacity to archive and manage the data. As a result, and initiated by SND, each university started a Data Access Unit (DAU), often consisting of librarians, archivists, legal advisors, and IT staff. The DAU was offered training by SND and gained access to SND’s network, where exchange of knowledge, policies, guides on good practice, workflows etc. was done. Interest groups were started, seminars, workshops and thematic network meetings were planned and offered. A few years on, the activity in the network is steadily increasing, as is the number of published research (meta)data. This presentation will demonstrate and highlight one possible way of building capacity for FAIR data sharing and reuse.

On this side of the compositing hut. Narrativity and compositional process in the fifth movement of Mahler’s Tenth Symphony
Creators: name: Pinto, Angelo
Publisher: name: De Musica
Year: 2019

description: In what way Mahler’s music, in its compositional process, can be regarded as a novel, both from a structural and hermeneutic point of view? Ever since Theodor W. Adorno published Mahler. Eine Musikalische Physiognomik (‘Mahler. A Musical Physiognomy’ 1960), it has been commonplace to discuss the music of Gustav Mahler in narratological terms: that is, to search his music for structural analogies with narrative using the approaches of ‘musical narratology’. However, writings of this field do not give enough attention on the authorial dimension of how composer constructs his musical ‘novel’ through the compositional process given that they are focused only on the work’s final version. In the analytic pathway displayed in this article, I suggest that in the extant sketches and draft of the fifth movement of the unfinished Mahler’s Tenth Symphony are detectable markers of a narrative strategy I call ‘narrativisation’ and that they become essential attributes of the hermeneutics of the movement. As a result, my analytic pathway suggests that the composer by his narrativising compositional process wanted to represent in the movement a process of writing, in a meta-referential play between an ‘inside’ and an ‘outside’ of what I define ‘his mental composing hut’.

Franz Schubert - una lettura della sonata D 959
Creators: name: Russo, Roberto
Publisher: name: De Musica
Year: 2019

description: Un uomo, un artista eccelso, una vita particolarmente travagliata; e una sonata per pianoforte che sembra essere lo spaccato della sua parabola artistica ed esistenziale. Il 1828 - anno di composizione della D. 959 - è uno dei periodi più prolifici di Franz Schubert, e anche l’anno della sua morte. Con questo capolavoro il musicista disegna un profondo percorso introspettivo fatto di reminiscenze ed intuizioni, lucide indagini e inedite architetture, desolante disperazione ma consapevole accettazione della condizione umana.

Στην Ελλάδα, παρά τις αρχικές αμφιβολίες ως προς την αναγκαιότητα ύπαρξης του εν λόγω θεσμού, τελικά επικράτησε η άποψη περί εισαγωγής της ρύθμισης στον Ποινικό Κώδικα. Στο πρώτο μέρος προσπαθήσαμε να προσδιορίσουμε τόσο τη νομική φύση όσο και την έννοια του εγκλήματος, ενώ παραθέσαμε και τα επιχειρήματα περί δικαιολογητικού λόγου ύπαρξής του. Στο δεύτερο μέρος αναλύσαμε διεξοδικά τις προϋποθέσεις που απαιτούνται ώστε μια εγκληματική συμπεριφορά να χαρακτηριστεί ως κατ’ εξακολούθηση έγκλημα. Τέλος, στο τρίτο μέρος προσεγγίσαμε τις ορθότερες δογματικά λύσεις σε διάφορα ζητήματα που προέκυψαν μετά την εισαγωγή δεύτερης παραγράφου στο άρθρο 98 του Ποινικού Κώδικα με το νόμο 2721/1999, όπως είναι αυτά της απόπειρας, της συμμετοχής και της παραγραφής του εγκλήματος.
description: In the present thesis we examined the institution of consecutive crime. In Greece, despite the initial doubts concerning the necessity of the above institution, the opinion in favor of its incorporation to the Criminal Code has prevailed. In the first part we attempted to demarcate the legal nature and the precise concept of the consecutive crime. Also, we touched upon the various arguments which have been proposed regarding its justifiable grounds. In the second part we elaborated on the sine qua non terms in order for a criminal behavior to be characterized as consecutive crime. Finally, in the third part, we discussed the most dogmatically correct solutions concerning the various issues which emerged due to the insertion of the second paragraph in the article 98 by the law 2721/1999. We especially focused on the issues of attempt, participation and crime's prescription.

description: The generation of high-quality assemblies, even for large eukaryotic genomes, has become a routine task for many biologists thanks to recent advances in sequencing technologies. However, the annotation of these assemblies - a crucial step towards unlocking the biology of the organism of interest - has remained a complex challenge that often requires advanced bioinformatics expertise. Here we present MOSGA, a genome annotation framework for eukaryotic genomes with a user-friendly web-interface that generates and integrates annotations from various tools. The aggregated results can be analyzed with a fully integrated genome browser and are provided in a format ready for submission to NCBI. MOSGA is built on a portable, customizable, and easily extendible Snakemake backend, and thus, can be tailored to a wide range of users and projects. We provide MOSGA as a publicly free available web service at https://mosga.mathematik.uni-marburg.de and as a docker container at registry.gitlab.com/mosga/mosga:latest.

description: We explore a model of interacting dark energy where the dark energy density is related by the holographic principle to the Hubble parameter, and the decay of the dark energy into matter occurs at a rate comparable to the current value of the Hubble parameter. We find this gives a good fit to the observational data supporting an accelerating Universe, and the model represents a possible alternative interpretation of the expansion history of the Universe.

A comparative analysis of the development of immersion programs in British Columbia and Quebec : two divergent sociopolitical contexts
Creators: name: Lamarre, Patricia B. Grace
Publisher: name: University of British Columbia
Year: 2009

description: Current explanations for the development of immersion programs in relation to language reform in Canada were found to be inadequate and superficial. The lack of attention to the existence of different sociopolitical contexts has, furthermore, flawed the sociological interpretation of programs. A comparative case study and multi-method approach was therefore proposed to examine the historical development of programs in two provinces with very different sociolinguistic and sociopolitical contexts, Quebec and British Columbia. Comparative analysis revealed that both commonalities and differences could be identified in the development of immersion programs in these two provinces and that these have implications for the political and sociological analysis of programs. In both contexts, it was seen that the implementation and expansion of programs has required similar organizational adjustments. The relationship of programs to language reform is, however, very different In Quebec, programs represent a community response to the changing status of French and are only indirectly related to federal efforts to implement a national policy of official bilingualism. In British Columbia, programs were initiated by parents, but eventually became directly related to federal involvement in language education and to Ottawa's efforts to implement a national language policy. By providing support to the parent association "Canadian Parents for French", Ottawa found a constituency in English Canada willing to promote official bilingualism. "Canadian Parents for French" and federal funding have played a critical role in the development of immersion programs in British Columbia; whereas in Quebec, neither of these elements has been an important factor in the expansion of programs. Although the development of immersion programs in Quebec and British Columbia has been framed by divergent language policies, in both provinces, the development of immersion programs reflects the adjustment of the English speaking community to the enhanced status of French. Similar sociological patterns were found in how the Anglophone community has made this adjustment and in how schools have been called upon to respond to societal change.

description: In this study, we use the concept of Bohmian trajectories to present a dynamical and deterministic interpretation for the gravity induced wave function reduction. We shall classify all possible regimes for the motion of a particle, based on the behavior of trajectories in the ensemble and under the influence of quantum and gravitational forces. In the usual approaches all information are obtained from the wave function evolution. But, on the basis of Bohm's deterministic quantum theory, we can investigate the motion of particle during the reduction processes. This leads to analytical and numerical results for the reduction time and equation of motion of the particle. In this regard, a new meaning will be provided for the reduction time.

description: By using a massless scalar field we examine the effect of an extra dimension on black hole radiation. Because the equations are coupled, we find that the structure of the fifth dimension (as for membrane and induced-matter theory) affects the nature of the radiation observed in four-dimensional spacetime. In the case of the Schwarzschild-de Sitter solution embedded in a Randall-Sundrum brane model, the extension of the black hole along the fifth dimension looks like a black string. Then it is shown that, on the brane, the potential barrier surrounding the black hole has a quantized as well as a continuous spectrum. In principle, Hawking radiation may thus provide a probe for higher dimensions.

description: The hidden Markov model (HMM) is a fundamental tool for sequence modeling that cleanly separates the hidden state from the emission structure. However, this separation makes it difficult to fit HMMs to large datasets in modern NLP, and they have fallen out of use due to very poor performance compared to fully observed models. This work revisits the challenge of scaling HMMs to language modeling datasets, taking ideas from recent approaches to neural modeling. We propose methods for scaling HMMs to massive state spaces while maintaining efficient exact inference, a compact parameterization, and effective regularization. Experiments show that this approach leads to models that are more accurate than previous HMM and n-gram-based methods, making progress towards the performance of state-of-the-art neural models.

This work demonstrates the unique potential of IR spectroscopy for the investigation of physical phenomena at the nanoscale occurring at the semiconductor-insulator interface in FET devices.

Images of the Native Canadian in National Film Board documentary film, 1944-1994
Creators: name: Wilkie, Tanis Eleanor
Publisher: name: University of British Columbia
Year: 2009

description: For fifty-seven years the National Film Board of Canada (NFB) has been interpreting Canada to Canadians through documentary films which have simultaneously reflected and shaped the identity of this country and its peoples. This study is concerned with the NFB's documentary film portrayal of Native Canadians. Over the half century that the NFB has been making films about Canada's indigenous peoples their portrayal has undergone much change. Comparisons are made in this study between three of the earliest examples and three of the most recent examples of such films, with regard to attitude, voice, and technique. The effect these choices have upon representation is also discussed. Changes in technical, artistic, and philosophical aspects of the documentary film genre have also had a significant effect upon representation of Native peoples over the past fifty years, and are considered as well. Educationally, the study considers issues of manipulation of knowledge and hidden curricula. Playing an increasingly important role in education today, the media is a powerful tool both for teaching and for the inculcation of social norms. Suggestions are made as to ways in which this medium can best be used in the classroom.
Improving Investment Suggestions for Peer-to-Peer (P2P) Lending via Integrating Credit Scoring into Profit Scoring

Subjects: subject: Risk Management (q-fin.RM)

description: In the peer-to-peer (P2P) lending market, lenders lend the money to the borrowers through a virtual platform and earn the possible profit generated by the interest rate. From the perspective of lenders, they want to maximize the profit while minimizing the risk. Therefore, many studies have used machine learning algorithms to help the lenders identify the "best" loans for making investments. The studies have mainly focused on two categories to guide the lenders' investments: one aims at minimizing the risk of investment (i.e., the credit scoring perspective) while the other aims at maximizing the profit (i.e., the profit scoring perspective). However, they have all focused on one category only and there is seldom research trying to integrate the two categories together. Motivated by this, we propose a two-stage framework that incorporates the credit information into a profit scoring modeling. We conducted the empirical experiment on a real-world P2P lending data from the US P2P market and used the Light Gradient Boosting Machine (lightGBM) algorithm in the two-stage framework. Results show that the proposed two-stage method could identify more profitable loans and thereby provide better investment guidance to the investors compared to the existing one-stage profit scoring alone approach. Therefore, the proposed framework serves as an innovative perspective for making investment decisions in P2P lending.

description: New results are reported of the computer simulations on the magnetic behaviour of magnetic arrays of nanoscopic dots, placed in cells of the square lattice. We show that the remanence magnetization $M_r$ decreases with the array size. For arrays 50x50, we investigate also the stability of the magnetic structure of an array in an oscillating magnetic field. The damage spreading technique reveals that this stability increases with the standard deviation $σ$ of the switching field of individual elements of the array. On the other hand, $M_r$ decreases with $σ$. An optimalization of the system (large $M_r$ and large stability) can then be reached at some intermediate value of $σ$.

Subjects: Archaeology

description: More than other disciplines, archaeology relies on the proper collection, documentation and publication of data because of excavations being an inherently destructive methodology. Moreover, research progress relies strongly on sharing this data to allow for comparison and contextualisation of findings and processes.

In the last decade, data sharing was boosted by the development of research infrastructures such as ARIADNE RI (Research Infrastructure), which now also provides the archaeological expertise in the EU-funded ATRIUM project. ATRIUM aims to consolidate and expand such services across the Arts and Humanities.

Despite all these activities, the SEADDA COST Action identified a fragmented landscape. Many countries lack the capacity and expertise to create and manage data according to the FAIR principles (Finable, Accessible, Interoperable, Reusable), or to ensure their long-term preservation. Moreover, researchers may have already heard about such research infrastructures but often are held back in sharing data through them. A major obstacle seems to be the lack of standards and guidance but also intuitive tools to feed one’s own data into a research infrastructure. Consequently, data are still not as widely available and cannot flow as easily as would be desirable to boost archaeology. Our session brings together researchers and infrastructure providers, archaeologists and archaeological scientists. We invite contributions spanning users and providers which identify and discuss the issues and challenges we face when using datasets, sharing data and keeping them available in the long-term, from the peculiarities of single data sets over the huge diversity of data archaeologists handle, to the current volatility of funding for research infrastructures. In the discussion, we will aim to define some guidelines on how data sharing can be facilitated on the different levels and what actions are needed by individuals and institutions to let data flow with research infrastructures as their safe and permanent havens.

description: The out-of-time-ordered correlators (OTOC) and the Loschmidt echo are two measures that are now widely being explored to characterize sensitivity to perturbations and information scrambling in complex quantum systems. Studying few qubits systems collectively modelled as a kicked top, we solve exactly the three- and four- qubit cases, giving analytical results for the OTOC and the Loschmidt echo. While we may not expect such few-body systems to display semiclassical features, we find that there are clear signatures of the exponential growth of OTOC even in systems with as low as 4 qubits in appropriate regimes, paving way for possible experimental measurements. We explain qualitatively how classical phase space structures like fixed points and periodic orbits have an influence on these quantities and how our results compare to the large-spin kicked top model. Finally we point to a peculiar case at the border of quantum-classical correspondence which is solvable for any number of qubits and yet has signatures of exponential sensitivity in a rudimentary form.

description: We propose a Point-Voxel DeConvolution (PVDeConv) module for 3D data autoencoder. To demonstrate its efficiency we learn to synthesize high-resolution point clouds of 10k points that densely describe the underlying geometry of Computer Aided Design (CAD) models. Scanning artifacts, such as protrusions, missing parts, smoothed edges and holes, inevitably appear in real 3D scans of fabricated CAD objects. Learning the original CAD model construction from a 3D scan requires a ground truth to be available together with the corresponding 3D scan of an object. To solve the gap, we introduce a new dedicated dataset, the CC3D, containing 50k+ pairs of CAD models and their corresponding 3D meshes. This dataset is used to learn a convolutional autoencoder for point clouds sampled from the pairs of 3D scans - CAD models. The challenges of this new dataset are demonstrated in comparison with other generative point cloud sampling models trained on ShapeNet. The CC3D autoencoder is efficient with respect to memory consumption and training time as compared to stateof-the-art models for 3D data generation.

description: The property of the ``perfect liquid'' created at RHIC is probed with anisotropic flow measurements. Different initial conditions and their consequences on flow measurements are discussed. The collectivity is shown to be achieved fast and early. The thermalization is investigated with the ratio of $v_4/v_2^2$. Measurements from three sectors of soft physics (HBT, flow and strangeness) are shown to have a simple, linear, length scaling. Directed flow is found to be independent of system size.

Perspectives on teaching and learning in career exploration programs for women:
Creators: name: Mullins, Kathleen Ann
Publisher: name: University of British Columbia
Year: 2009

description: This study provides detailed accounts of the perspectives on teaching and learning experienced by the instructors and participants in three career exploration programs for women. One of the programs was located at a community college, one at a private college, and one was offered through a non-profit agency. The perspectives of the women are represented by each individual's expressed attitudes, feelings, and ideas about how they experienced teaching and learning. I also examine and relate the accounts of the women to the ways in which teaching processes and learning objectives were created, influenced, and/or constrained by the broader social and administrative context in which the programs take place. Therefore, the study addressed the following broad questions: (1) What values and attitudes toward teaching and learning are expressed by instructors and how do they shape the pedagogical interactions that take place in these career education programs? (2) What has been the participants' experience of learning in these programs? And, (3) In what ways does the social, institutional, and political context in which the programs take place affect the teaching/ learning environment? This study originates from my interest as a feminist educator to gain a greater understanding of how critical and feminist pedagogical approaches are manifested in actual practice, in this case, three particular career exploration programs. Information for the study was gathered from program instructors through semi-structured interviews; through an informal focus group in each program with volunteer students; and by reviewing relevant program related materials. After providing detailed accounts of the perspectives of the instructors, participants, and descriptions of each program, the external factors which create, influence, and constrain the nature of the programs, and the voices of the instructors and participants are explored in relation to the literature reviewed for the study. This analysis revealed that the instructors employed teaching approaches which are consistent with the values and aims of critical feminist pedagogy. However, teaching approaches were also applied which appear to reside within traditional educational approaches. Thus, in these particular contexts, the instructors created and acted within a teaching-learning environment which both reproduced and challenged the status quo. The methodological approach utilized in this study illustrated how adult educators concerned with the liberatory possibilities of adult education must invariably operationalize these ideas in complex, constrained, and often contradictory social sites which act to shape the possibilities of instruction. It did so by directing attention to both the social actors and the social and political processes that act to create and organize specific adult education activities.

description: Spin-to-charge conversion (SCC) involving topological surface states (TSS) is one of the most promising routes for highly efficient spintronic devices for terahertz (THz) emission. Here, the THz generation generally occurs mainly via SCC consisting in efficient dynamical spin injection into spin-locked TSS. In this work, we demonstrate sizable THz emission from a nanometric thick topological insultator (TI)/ferromagnetic junction - SnBi$_2$Te$_4$/Co - specifically designed to avoid bulk band crossing with the TSS at the Fermi level, unlike its parent material Bi$_2$Te$_3$. THz emission time domain spectroscopy (TDS) is used to indicate the TSS contribution to the SCC by investigating the TI thickness and angular dependence of the THz emission. This work illustrates THz emission TDS as a powerful tool alongside angular resolved photoemission spectroscopy (ARPES) methods to investigate the interfacial spintronic properties of TI/ferromagnet bilayers.

description: For some physics students, the concept of a particle travelling faster than the speed of light holds endless fascination, and Cherenkov radiation is a visible consequence of a charged particle travelling through a medium at locally superluminal velocities. The Heaviside--Feynman equations for calculating the magnetic and electric fields of a moving charge have been known for many decades, but it is only recently that the computing power to plot the fields of such a particle has become readily available for student use. This article investigates and illustrates the calculation of Maxwell's D field in homogeneous isotropic media for arbitrary, including superluminal, constant velocity, and uses the results as a basis for discussing energy transfer in the electromagnetic field.

description: We have carried out extensive comparative studies of the structural and transport properties of CaRuO$_3$ thin films grown under various oxygen pressure. We find that the preferred orientation and surface roughness of the films are strongly affected by the oxygen partial pressure during growth. This in turn affects the electrical and magnetic properties of the films. Films grown under high oxygen pressure have the least surface roughness and show transport characteristics of a good metal down to the lowest temperature measured. On the other hand, films grown under low oxygen pressures have high degree of surface roughness and show signatures of ferromagnetism. We could verify that the low frequency resistance fluctuations (noise) in these films arise due to thermally activated fluctuations of local defects and that the defect density matches with the level of disorder seen in the films through structural characterizations.

description: We discuss several possible experimental signatures of the Bose-Einstein condensation (BEC) transition for an ultracold Bose gas in an inhomogeneous optical lattice. Based on the commonly used time-of-flight imaging technique, we show that the momentum-space density profile in the first Brillouin zone, supplemented by the visibility of interference patterns, provides valuable information about the system. In particular, by crossing the BEC transition temperature, the appearance of a clear bimodal structure sets a qualitative and universal signature of this phase transition. Furthermore, the momentum distribution can also be applied to extract the condensate fraction, which may serve as a promising thermometer in such a system.

description: This paper investigates the effect of interest rate on private investment and determine the threshold level beyond which interest rate becomes detrimental to private investment in Ghana. The paper employed annual time series data from 1986-2016. To investigate the effect of interest rate on private investment, the paper employed the autoregressive distributed lag (ARDL) model, while the quadratic function and conditional least square procedures were employed to estimate the interest rate threshold. Results from the ARDL model revealed positive long and short run effect of interest rate on private investment, thus confirming the McKinnon-Shaw hypothesis in Ghana. However, results from the quadratic function and conditional least square model found the threshold of 23.59% and 24% respectively, beyond which interest rate impacts negatively on private investment in Ghana. Thus, the paper recommends the deepening of the financial sector reforms, improving competition in the financial sector as well as maintaining macroeconomic stability.
Finite N Index and Angular Momentum Bound from Gravity

description: We exactly compute the finite N index and BPS partition functions for N=4 SYM theory in a newly proposed maximal angular momentum limit. The new limit is not predicted from the superconformal algebra, but naturally arises from the supergravity dual. We show that the index does not receive any finite N corrections while the free BPS partition function does.

description: The “ROCEEH Out of Africa Database” (ROAD) is the largest compilation of archaeological datasets covering Africa and Eurasia from 3,000,000 to 20,000 years ago. When the project began in 2008 (https://www.hadw-bw.de/en/research/research-center/roceeh/home), one goal was to create an open-access, online, research database to answer large-scale questions about early humans expansions. ROAD gathers data from fields of archaeology, paleoanthropology, paleontology and paleobotany in a geographic framework.

Here, we present recent advances in querying ROAD. We discuss how ROCEEH provides its users with data andfocus on a new, user-friendly feature that facilitates data retrieval. The new interface, called “Ask ROAD,” embodies our philosophy of making the data we collect as FAIR as possible.

Queries in ROADWeb are performed in various ways: simple filters on one table provide basic results; an SQL query tool allows the joining of several tables; a SPARQL endpoint is also available; finally, we collaborate with partners to tailor complex queries. Results can be viewed in ROADWeb or accessed through a URL, and exported in several interoperable formats.

Experience with users motivated us to create “Ask ROAD”. This intuitive interface works in a scaffolded way with five sequential steps: 1) select geographic region and/or site type; 2) choose types of assemblages and/or define timeframe; 3) specify details about assemblages; 4) perform unions of datasets; and 5) conduct detailed searches. After each step, a table pops up, which users can download in their preferred format. References are generated after the first step and attributes displayed at any time.

We plan to add more features in the future, for example a routine to extract data from ROAD and process it using statistical packages such as R. We encourage you to visit ROAD (https://www.roceeh.uni-tuebingen.de/roadweb/) and provide expanded access to anyone interested. Discover for yourself what ROAD can do!

description: The aim of this paper is to provide complementary quantitative extensions of two results of H.S. Shapiro on the time-frequency concentration of orthonormal sequences in $L^2 (\R)$. More precisely, Shapiro proved that if the elements of an orthonormal sequence and their Fourier transforms are all pointwise bounded by a fixed function in $L^2(\R)$ then the sequence is finite. In a related result, Shapiro also proved that if the elements of an orthonormal sequence and their Fourier transforms have uniformly bounded means and dispersions then the sequence is finite. This paper gives quantitative bounds on the size of the finite orthonormal sequences in Shapiro's uncertainty principles. The bounds are obtained by using prolate spheroïdal wave functions and combinatorial estimates on the number of elements in a spherical code. Extensions for Riesz bases and different measures of time-frequency concentration are also given.

description: We discuss results and future plans for low-energy reactions that play an important role in current nuclear astrophysics research and that happen to concentrate around the region of A=7. The 7Be(p,gamma)8B and the 3He(4He,gamma)7Be reactions are crucial for understanding the solar-neutrino oscillations phenomenon and the latter one plays a central role in the issue of cosmic 7Li abundance and Big-Bang Nucleosynthesis. We also present results regarding the host dependence of the half life of the electron-capture 7Be radio-nuclide.

description: Η παρούσα διπλωματική εργασία εξετάζει από τη σκοπιά του χωρικού μουσειολογικού σχεδιασμού τη μεγάλης κλίμακας έκθεση TRACK: A Contemporary City Conversation. Η έκθεση αυτή διοργανώθηκε από το δημοτικό μουσείο σύγχρονης τέχνης S.M.A.K. στο δημόσιο χώρο της Γάνδης, κατά την περίοδο Μάιος-Σεπτέμβριος 2012. Σκοπός της μελέτης είναι να ανιχνευτεί ο τρόπος και οι προϋποθέσεις που ορίζουν τον επιτυχημένο σχεδιασμό μιας έκθεσης στο δημόσιο αστικό χώρο. Αρχικά περιγράφονται το νοηματικό-μουσειολογικό πλαίσιο της έκθεσης καθώς και η ιδεολογία που τη διέπει. Στο σημείο αυτό ο αναγνώστης έχει στα χέρια του όλα τα στοιχεία που ορίζουν το υπόβαθρο πάνω στο οποίο θα εξελιχτεί ο χωρικός μουσειολογικός σχεδιασμός. Στη συνέχεια αναλύεται διεξοδικά ο χωρικός σχεδιασμός της έκθεσης δίνοντας ιδιαίτερο βάρος στις ευαίσθητες ισορροπίες που αναπτύσσονται μεταξύ του εκθεσιακού χώρου και του αρχιτεκτονικού χώρου στον οποίο εφαρμόζεται η έκθεση, το δημόσιο αστικό χώρο. Η εργασία ολοκληρώνεται με την κριτική αποτίμηση του εκθεσιακού σχεδιασμού. Αναλύεται η ταύτιση νοηματικού–φυσικού σχεδιασμού καθώς αυτή είναι που ορίζει το συνολικό βίωμα της έκθεσης και συνεπώς το βαθμό επιτυχίας της.
description: The present dissertation thesis examines the large scale exhibition TRACK: a Contemporary City Conversation from the perspective of the spatial exhibition design. The exhibition was held by the municipal museum of contemporary art S.M.A.K. in the public space of Ghent in Belgium. The purpose of the study is to detect the conditions and the manner that define the successful exhibition design in public urban space. The thesis starts by describing the museological concept of the exhibition and its ideology. At the end of this chapter the reader is aware of the matters that define the basis on which the spatial exhibition design will be evolved. Then the designing process of the exhibition it is analytically presented by focusing on the relation between the exhibition space and the public urban space. The problematic of the paper concludes with the critical assessment of TRACK’s exhibition design. At this part we are focusing on the relation between the conceptual and spatial design of the exhibition knowing that this subject defines the visitor’s overall experience and therefore the success of the exhibition.

description: Recent work shows that strong stability and dimensionality freedom are essential for robust numerical integration of thermostatted ring-polymer molecular dynamics (T-RPMD) and path-integral molecular dynamics (PIMD), without which standard integrators exhibit non-ergodicity and other pathologies [J. Chem. Phys. 151, 124103 (2019); J. Chem. Phys. 152, 104102 (2020)]. In particular, the BCOCB scheme, obtained via Cayley modification of the standard BAOAB scheme, features a simple reparametrization of the free ring-polymer sub-step that confers strong stability and dimensionality freedom and has been shown to yield excellent numerical accuracy in condensed-phase systems with large time-steps. Here, we introduce a broader class of T-RPMD numerical integrators that exhibit strong stability and dimensionality freedom, irrespective of the Ornstein-Uhlenbeck friction schedule. In addition to considering equilibrium accuracy and time-step stability as in previous work, we evaluate the integrators on the basis of their rates of convergence to equilibrium and their efficiency at evaluating equilibrium expectation values. Within the generalized class, we find BCOCB to be superior with respect to accuracy and efficiency for various configuration-dependent observables, although other integrators within the generalized class perform better for velocity-dependent quantities. Extensive numerical evidence indicates that the stated performance guarantees hold for the strongly anharmonic case of liquid water. Both analytical and numerical results indicate that BCOCB excels over other known integrators in terms of accuracy, efficiency, and stability with respect to time-step for practical applications.
