Abstract
We present late-time radio observations of GW170817, the first binary neutron-star (NS) merger discovered through gravitational waves (GWs) by the advanced Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo detectors. Our observations, carried out with the Karl G. Jansky Very Large Array (VLA), were optimized to detect polarized radio emission, and thus to constrain the linear polarization fraction of GW170817. At an epoch of ≈244 days after the merger, we rule out linearly polarized emission above a fraction of ≈12% at a frequency of 2.8 GHz (99% confidence). Within the structured jet scenario (a.k.a. successful jet plus cocoon system) for GW170817, the derived upper limit on the radio continuum linear polarization fraction strongly constrains the magnetic field configuration in the shocked ejecta. We show that our results for GW170817 are compatible with the low level of linear polarization found in afterglows of cosmological long γ-ray bursts (GRBs). Finally, we discuss our findings in the context of future expectations for the study of radio counterparts of binary NS mergers identified by ground-based GW detectors.
Dessiner d’après le modèle à l’Académie de Marseille
Authors: Vi-Tong Nelly 
Published: July 2018

L’exposition qui s’est tenue en 2016 à Marseille a mis en relief les particularismes de l’une des plus importantes académies méridionales du xviiie siècle. Affiliée à l’Académie royale de peinture et de sculpture, l’institution phocéenne se doit, scrupuleusement, de rendre des comptes à son directeur Michel François Dandré-Bardon (1700-1785). Ce dernier noue une longue et riche relation épistolaire avec les professeurs marseillais. En 1754, Dandré-Bardon adresse à ces derniers un précieux lot d’académies dessinées. Il y joint une conférence intitulée Sur la manière de poser le modèle et de le dessiner. Cet article interroge la pratique du dessin d’après nature et le statut du modèle à Marseille, et se propose d’en souligner les spécificités par comparaison avec d’autres établissements contemporains.
Medieval Porticoes of Rome: New Methods and Technologies for Revealing Rome’s Architectural and Urban Heritage
Authors: Anders Selena Kathleen 
Published: July 2018

At the moment there are few comprehensive texts or instruments that allow architects, designers, historians, planners or even students the ability to understand the complex layers of a city’s urban fabric. As a result, this paper was prepared in order to be uploaded to a digital tool that allows for such exploration of the built environment. The transformation of the city of Rome is documented in a number of sources and as a result makes it the ideal city for study of architectural and urban evolution. As a case study in digital documentation this paper examines the medieval façade porticoes of Rome at three scales: urban, architectural, and detail. The identification and mapping of these structures, are shown together allowing one to examine them in relation to historic and present day city maps. In addition, their location is analyzed in relation to ancient Roman streets and historic processional routes, to observe the connection amongst their location and that of major thoroughfares of antiquity, the Middle Ages, and the Renaissance. At the architectural scale, the detailed documentation in plan and elevation reveal four distinct variations that existed in the use of the residential façade portico. At the scale of architectural detail, an inventory of reused architectural elements or spolia that make up the residential porticoes reveal the reuse of ancient Roman column shafts, bases and capitals as well as the medieval masons’ preference for the use of the Ionic capital in particular. This paper prepares a methodology for digital deployment of traditional scholarship focused on architecture and the built environment.
Contribution of planned built environments to city transformation: urban design practice in Montreal from 1956 to 2016.
Authors: Racine Francois 
Published: July 2018

Contributions to the literature on Canadian urbanism and, in particular, Canadian urban design, despite some notable exceptions, are relatively limited. The presentation explains from an urban form perspective the practice of urban design in Montreal from the mid-twentieth century onwards. The research seeks to interpret the development of urban design practice in Montreal by reviewing a representative sample of urban projects built over the past six decades. The urban projects are used to illustrate the different renewal strategies adopted, to understand how urban design ideology/ideas have changed over time in Montreal and how they have influenced the spatial organization, form, and aesthetic of the city. The principal theoretical and methodological contribution of the research is to develop a morphological framework to study and understand the physical-spatial mode of organization of planned built environments and to study their relationship to urban form (Racine 2016). The author uses this chronological investigation of the cases to reveal how each school of thoughts that has emerged in the discipline of urban design since its foundation in 1956 (Krieger, Saunders, 2009), has addressed the problems of modernist urban planning and to move the field of urban design thinking forward. The first results of our analysis show the importance of morphological and spatial relations between vernacular and planned built environments. The morphological issue of continuity of urban space is crucial to assure a certain level of urban equity between citizens and to assure the sustainability of the development of the city as a whole.
The Cyclicality of the Anthropic Space in Urban Morphology: an architectural perspective.
Authors: Marzot Nicola 
Published: July 2018

This paper intends to offer a systematic reflection on the significance of “cyclicality” in the processual development of the anthropic space, ranging from the territorial to the architectural scale. The reflection will essentially focus on those theoretical contributions emerging from the disciplinary field of architecture and urban design. Among them, three outstanding research positions can be clearly listed over the last century and will therefore be analyzed in-depth: Saverio Muratori’s definition of “Storia Operante”; John Habraken’s system of “Support and infill” and the Re_Cycle Italy research network program on “Recycle”. Beyond those stances, modern precedents can be traced back in some Neo avant-garde movements, especially Japanese Metabolism and Radical architecture. The topic rapidly assumes nowadays an increasing interest because of the financial crisis which is still affecting the world on a global scale and the subsequence necessity to critically reflect on the responsible reuse of heritage to face the challenging demand of a sustainable approach in the building market. The reflection is intentionally limited to the western country panorama, since there is an historical evidence of its long-lasting legacy in the transformation of the city form over the millennia. One of the expected results of the paper is to contribute to the definition of a new design strategy, in order to profit from the increasing presence of waiting lands and vacant buildings to drawn the society of the near future, offering room for experimentation to the emerging driving forces which claim a role in its deployment.
Preferred urban public spaces through social media: historic cities of the province of Alicante (Spain).
Authors: Martí Pablo , Serrano-Estrada Leticia , Nolasco-Cirugeda Almudena 
Published: July 2018

Understanding the role of urban public spaces in today’s historic Spanish Mediterranean cities is a key priority for researchers and urban professionals. Increasingly, social media showcases users’ preferences, a trend that can provide an indication as to why some urban public spaces are preferred over others. This research focuses on preferred urban public spaces in historic cities in the province of Alicante (Spain) and has two objectives: to identify their urban morphological features; and, to recognise similar traits in terms of their location within the urban structure. The method involved: first, analysing Foursquare social media data on user preferences about urban public spaces; second, studying spatial and functional urban attributes; and third, recognising their role within the city structure. The results demonstrate that the preferred urban spaces share morphological attributes; a central position in the urban structure; mixed-use ground floor activities; and the presence of relevant urban public facilities.

This negletc state produces a serious problem related to a wider phenomenon of abandonment of entire portions of italian territories. Realities that differ form the city because of their morphology: Does urban shape represent an urban limit? or is it an alternative testimony to the city? Research purpose is to understand how relationship, between these cases and the territory, works; in particular during the absence of the main component: the human one. The case study Santo Stefano di Sessanio, an ancient village in the center of Italy, inhabited until 90's, shows how the examination of urban shape represents the potentiality of his own revitalization. By relating his historical identity to the scattered hotel projectual approach, it contributes to combine conservation, valorization and sustainability of the existing building fabric, in order to claim the authenticity of these villages declaring their own autonomy and dimension to major urban centers polarization. In this example transformation is meant as conscious project that grow up from the built reality not from the project itself, transformation as knowledge of urban facts, tool to approach to the structure of this reality.

Urban form in the tourist cities of the coast of the Canary Islands. The morphologies of leisure
Authors: Temes Córdovez Rafael R. , Simancas Cruz Moisés , García Amaya Alicia , Peñarrubia Zaragoza María Pilar 
Published: July 2018

The tourist city has been a space with few and weak reflections from the urban discipline. The developed planning, at best, has been uncritically exported from the residential city. However, in these cities, almost 12% of Spanish GDP is generated. The vast majority of Spanish coasts, especially on the Mediterranean coast and in the archipelagos, are occupied by large areas of holiday cities. Many of them were born in the first boom of Spanish tourism in the 60's. The mass tourism model, predominant in our coast, also generates a mass city. The morphology of this city does not follow the common and more consolidated patterns of the residential city. Today many of these tourist destinations begin to show of obsolescence. For this reason, the analysis of its urban form is a valuable tool in the face of its renovation project. In this work, we propose the analysis of the tourist micro-destinations of the Canarian archipelago. In order to this we will identify the main morphological patterns and characterize them from the analysis of a set of descriptive indicators related to public and private space. References Gaja, F.

A study on the history of urban morphology in China based on discourse analysis Limeng Zhang¹, Andong Lu¹ ¹School of Architecture and Urban Planning, Nanjing University.

Since its first introduction to the Chinese context about 20 years ago, the key ideas and concepts of urban morphology underwent a significant phenomenon of ‘lost in translation’. Different origins of morphological thoughts, different versions of translation, as well as different disciplinary context, have all together led to a chaotic discourse. This paper reviews the key Chinese articles in the field of urban morphology since 1982 and draws out a group of persistent keywords, such as evolution, axis, urban fringe belt, plan unit and plot, that characterize the morphological approach to urban issues. By reviewing the transformation of the definition of these keywords, this paper aims to generate an evolutionary map of landmark ideas and concepts, based on which, four stages in the development of urban morphology in China can be identified: emergence, growth, maturity, practice. The mapping methodology could be extrapolated to other words, and the obtained evolutionary map could be a basic tool for further study. References Conzen M. R.

The land acquisition and real estate development have caused rapid disappearance and decline of a large number of traditional villages, resulting in "urban villages" in China. They seem chaotic, but contain rich and colorful social life. The living environment is really harsh, but people always maintain close relationship with each other. They are different from neither the modern urban nor traditional villages, but they have their own unique vitality. Such heterogeneous space is always a symbol of historical change and cultural collision which, according to the French philosopher Michel Foucault, can be called Heterotopias. In order to study this heterotopic phenomenon, the triangular area of Guandongdian district in Beijing has been chosen as the object of this case study. With the in-depth investigation of interviews, observation, statistics and sketches, this paper is trying to interpret the characteristics of the heterotopic state of the urban village from three aspects of social form, urban morphology and architectural feature. Eventually, in order to keep the complexity and diversification of urban village, several strategies are put forward for reference to future transforming practice. References Foucault, M.

Linear parks understood as vertebration instruments of the city
Authors: Bosch Reig Ignacio , Bosch Roig Luis , Marcenac Valeria , Salvador Luján Nuria 
Published: July 2018

This research raises as thesis the idea that Linear Park is an urban instrument capable of vertebrate the city and, consequently, of regenerate it. To this end, ten parks strategically located in big cities such as Rio de Janeiro, London, Paris, Madrid, Barcelona, ​​or in medium or small cities such as Valencia, Castellón or Figueres, have been analyzed. Of this analysis we have deduced some characteristics that are considered key in the linear and transversal vertebration of the city, such as: - Green axis-corridor approach - Sequence of events with integration of public buildings - Continuity derived from the union of different areas - Promotion of active leisure activities, individual or collective: sports, cultural, .... - Capability of relation and regeneration of ecosystems: forest, meadow, orchard, nurseries, water, city, .... - Capability to restore environment, with reduction in CO2, in noise pollution, ... - Establish relations between the city and the territory with definition of natural parks - Contribute to prevent thermal inversion in the city - Establish a beginning and an end as recognizable elements in city. - Confrontation of opposites: static or dynamic; soft (green) or hard (pavement); unitary or fragmentary, cartesian or organic, ... The parks thus understood can be organized in diverse typologies, such us: classic order; in net; upholstery-continuos map; linear order with grooves, tapes or bands; landscaper and naturalist; ... .. The work delves into these themes by recognizing tools of interest such as: harmonic relationship; human scale; non-guided tours; sensory experimentation: spaces, sights, aromas, sounds, colorful, ...; unexpected and random; pragmatic and passionate; order within disorder; activation of spaces without hierarchies or apriorisms; flee from monotony; evocations; ...

Shape of cadastral plot and band of pertinence. Meaning for Architectural Design
Authors: Carlotti Paolo 
Published: July 2018

Some our studies of urban morphology, implemented on historical and contemporary urban fabric maps, allow us to believe that the shape of the lot and of band of pertinence of a pathway are essential to reading the formative urban process. Different phases of formative process of an urban center seems, in fact, to be recognizable in the of shape of lot and interaction between lots and path. These morphological shapes (lots) are the result of different centrality that are produced in the building fabric and, consequently, the restructuring pathways are important for understanding rules and causes of urban and architectural transformation of the city. This paper aims to offer a contribution to the definition of the elements of urban morphology. This research, part of a series of research, carried out in the Lab.
