Abstract Today the so-called “smart city” is connoted by massive implementation of novel, digital technology, which is often considered as the best solution to global issues affecting contemporary cities. Sophisticated and low-cost technological solutions are developed also in the field of noise monitoring and they are expected to play an important role for acousticians, city planners and policy makers. However, the “smart city” paradigm is controversial: it relies on advanced technological solutions, yet it fails to consider the city as a social construct and it often overlooks the role of citizens, in the quest for technological advances and novel methods. This is especially true in the field of smart acoustic solutions addressing the issue of urban quiet areas: main methods and technologies developed so far barely involve citizens and consider their preferences. This contribution tackles this challenge, by illustrating a novel mixed methodology, which combines the soundscape approach, the citizen science paradigm and a novel mobile application - the Hush City app - with the ultimate goal of involving people in identifying, assessing and planning urban quiet areas. Firstly, the theoretical background and the methods applied are described; secondly initial findings are discussed; thirdly potential impact and future work are outlined.

Similar Claim

In his original 1965 article, Christopher Alexander argued that master planned cities ultimately failed because the designs elaborated followed a tree structure as opposed to a more desirable semilattice structure present in organic cities. In this article, I argue that a similar claim can be made with urban infrastructure systems planning. As cities expanded and became increasingly complex in the 20th century, the responsibility to plan and design urban infrastructure was distributed to separate agencies that seldom communicate and coordinate with one another. In the global context to make cities more sustainable and resilient, a better integration of infrastructure systems may hold much potential. After recalling Alexander’s main concepts, I examine how current infrastructure systems are naturally interdependent. I then discuss the role of integration, by notably proposing an integration-decentralization matrix, with four quadrants, illustrated by using practical examples. The quadrants are current paradigm, siloed distribution, localized integration, and integrated decentralization. Overall, a better integration of urban infrastructure can offer significant benefits to a city, and it may be time to seriously revisit our current urban infrastructure systems planning practice.

Entrainment Mixing

AbstractCloud models show that precipitation is more likely to occur in larger shallow clouds and/or in an environment with more moisture, in part as a result of decreasing the impacts of entrainment mixing on the updrafts. However, the role of cloud size in shallow cloud precipitation onset from global satellite observations has mostly been examined with precipitation proxies from imagers and has not been systematically examined in active sensors, primarily because of sensitivity limitations of previous spaceborne active instruments. Here we use the more sensitive CloudSat/CALIPSO observations to identify and characterize the properties of individual contiguous shallow cumulus cloud objects. The objects are conditionally sampled by cloud-top height to determine the changes in precipitation likelihood with increasing cloud size and column water vapor. On average, raining shallow cumulus clouds are typically taller by a factor of 2 and have a greater horizontal extent than their nonraining counterparts. Results show that for a fixed cloud-top height the likelihood of precipitation increases with increasing cloud size and generally follows a double power-law distribution. This suggests that the smallest cloud objects are able to grow freely within the boundary layer but the largest cloud objects are limited by environmental moisture. This is supported by our results showing that, for a fixed cloud-top height and cloud size, the precipitation likelihood also increases as environmental moisture increases. These results are consistent with the hypothesis that larger clouds occurring in a wetter environment may be better able to protect their updrafts from entrainment effects, increasing their chances of raining.

Compositional Process

Tree-structured neural networks have proven to be effective in learning semantic representations by exploitingsyntactic information. In spite of their success, most existing models suffer from the underfitting problem: they recursively use the same shared compositional function throughout the whole compositional process and lack expressive power due to inability to capture the richness of compositionality.In this paper, we address this issue by introducing the dynamic compositional neural networks over tree structure (DC-TreeNN), in which the compositional function is dynamically generated by a meta network.The role of meta-network is to capture the metaknowledge across the different compositional rules and formulate them. Experimental results on two typical tasks show the effectiveness of the proposed models.

Abstract:This innovative perspective on historical linguistics, linguistics, and applied linguistics examines these areas of study with the role of trees in mind. It covers the quest for the founding father of historical linguistics - from the German Schleicher through the Scots, Stewart and Hutton, to the Americans, Whitney and Peirce, and the Swiss, Saussure. A brief but sweeping review of early linguistics and language study before the advent of cognitivism reveals American structuralism and immediate constituent analysis in descriptive linguistics relying on the tree structure even prior to the time transformative generative grammar was institutionalized.Keywords: Historical Linguistics, Linguistics, Language Teaching, Trees.Título en español: La lingüística histórica, la lingüística, y la lingüística aplicada: Un estudio motivado por los árboles.Resumen:Esta perspectiva original sobre la linguística histórica, la linguística, y la linguística aplicada examina estas áreas de estudio desde un punto de vista arbóreo. Cubre la búsqueda de un padre fundador de la lingüística histórica - desde el alemán, Schleicher, y los escoceses, Stewart y Hutton, a los norte-americanos, Whitney y Pierce y el suizo, Saussure. Una breve pero vasta revista de la primitiva lingüística y el estudio de lenguas antes de la aparición del cognitivismo revela que el estructuralismo americano y el análisis de los constituyentes inmediatos en la lingüística descriptiva dependen de la estructura arbórea incluso antes que la gramática generativa transformativa fue institucionalizada.Palabras Claves: Lingüística Histórico, Lingüística, Enseñanza de Lenguas, Árboles

Due to the difficulty of obtaining information about the dough of Balinese traditional snack(jajanan tradisional Bali), causing Hindu community in Bali, do not know the importance of the role of traditional snack in Yadnya ceremony. Rapid technological developments that pushed for an alternative in order that information is easily obtained by making an application. Implementation of tree structure in the process of preparing an Android-based information allow users to know the material linkages with other materials. Other support such as recursive algorithm which is used to ease in calculation of the amount of materials displayed on the Application. therefore expected with this application, Hindu community in Bali will be easier to understand and find out information about the dough of Balinese traditional snack.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.
