Making WiFi work in multi-hop topologies: Automatic negotiation and allocation of airtime
2015
We propose a solution for mitigating the performance impairments of CSMA/CA protocols in multi-hop topologies based on the dynamic adaptation of the contention process experienced by nodes in a wireless network. A distributed protocol is used to negotiate the channel airtime for a node as a function of the traffic requirements of its neighbourhood, taking into account bandwidth reserved for the control operations. A mechanism is provided for a node to tune its contention window depending on its allocated airtime. Different from previous schemes, a node's contention window is fixed in size unless the traffic requirements of its neighbourhood change. The scheme is implemented on legacy commer…
Multicultural and Multifaceted Canada
2018
Describing the system of education in Canada is akin to trying to describe the nation itself—complex. It is perhaps difficult to pinpoint defining features, the country being viewed by many on the world stage as strong and stable; yet on home soil, many Canadians struggle to articulate where the essence of their country lies. [I am one of those Canadians. That being said, I feel very fortunate to live, work and raise my children in Canada. I look out my window and see the Rocky Mountains; I breathe clean air and have clean water to drink any time I turn my faucets on; my children walk to school in what I feel is as safe a neighbourhood as you will find in a large Canadian city; and, I am fo…
Adopt a Neighborhood: When Planners Meet Schoolchildren
2015
Throughout this paper we will present a project that revolves around the idea of the neighbourhood as an ‘identity container’ and aims at bridging the gap between traditional planning programmes and the new challenges linked both to the crisis of public spaces and to participatory planning. During the last two years, our University has been working in cooperation with the Municipality of Palermo and many primary and secondary schools of the city on a project called ‘La scuola adotta il quartiere’ (‘Schools Adopt Neighbourhoods’). Within the project, planning students from the University guided the schoolchildren (8- to 13-years old) to the discovery of their neighbourhood and its community.…
Relating RSS News/Items
2009
Merging related RSS news (coming from one or different sources) is beneficial for end-users with different backgrounds (journalists, economists, etc.), particularly those accessing similar information. In this paper, we provide a practical approach to both: measure the relatedness, and identify relationships between RSS elements. Our approach is based on the concepts of semantic neighborhood and vector space model, and considers the content and structure of RSS news items. © 2009 Springer Berlin Heidelberg.
Assessing environmental noise exposure: does the size of the neighbourhood matter?
2013
International audience; In environmental epidemiology, studies rely on the quantification of subject'sexposures in a surface defined as the subject exposure area. For outdoor exposure, this area is often considered as the subject's neighbourhood. But, depending on the authors, the size and the nature of this neighbourhood differs, making difficult to compare results. In order to study the impact of the sampling surface on the noise exposure values affected to a subject, a high definition environmental noise model has been builton a middle-sized French city. Outdoor neighbourhood noise indices were computed at 10,394 residential buildings, using eight different sizes of buffers defined by di…
How green neighbourhoods make cities more compact?t? A 2D microeconomic perspective
2014
National audience; We analyse the emergence of scattered residential development, a key characteristic of sprawl. We analyse a 2D urban economic model with neighbourhood interactions among households (social contacts) and with farmers (who produce green amenities). Starting from a cross-shaped road network and CBD, we analytically establish the existence and characteristics of residential leapfrogging that breaks up the compact development of the city. We extend our analysis by numerical experiments based on observed or econometrically estimated parameters. We nd that the shape of built up areas in uences the decision or not to jump over undeveoped land or to stick to the contiguous urban f…
Challenges of the Covid-19 pandemic and design responses in public space: Towards strategies for resilient post-Covid cities
2022
The Covid-19 pandemic triggered governments and designers to revalue and redesign public spaces. This paper focuses on the various design responses to Covid-19 proposed and implemented in public spaces. In particular, we identify the kinds of challenges that such design responses address and the strategies that they use. We selected 56 design examples, largely collected from internet sources. By analyzing the design examples we identified five Covid-related challenges that were addressed in public space: sustaining amenities, keeping a distance, feeling connected, staying mentally healthy, and expanding health infrastructures. For each challenge, we articulated 2 to 6 design strategies. The…
Analysis of needs from the Human Scale Development Theory: the case of two vulnerable neighbourhoods of Valencian Region (Spain)
2019
Este artículo deriva del trabajo que, en el marco del Máster de Cooperación Internacional al Desarrollo de la Universitat de València (España), fue realizado en el año 2018 por Glòria Maria Caravantes López de Lerma y dirigido por el Dr. Albert Mora Castro, del Departamento de Sociología y Antropología de la citada Universidad.
“Serpentone Reload” an Experience of Citizens Involvement in Regeneration of Peripheral Urban Spaces
2015
Suburbs are often very contradictory places. Despite great part of urban population live there, these parts of cities are mostly considered as degradation places. The topic of suburbs regeneration is relevant today. Nevertheless, often expensive interventions implemented by local authorities fail to regenerate their public spaces. This paper presents the experience of “Serpentone reload”, a workshop based on participatory reactivation of abandoned or underused spaces and buildings in “Cocuzzo/Serpentone” neighbourhood in Potenza (Basilicata, Italy). The workshop particularly focused on the reuse of the “Ship”, an underground building, completed in 2010, never used, because it has been perce…
An Analysis of the Residential Segregation of Foreigners in the Municipality of Palermo
2021
Ethnic residential segregation in Italy is emerging as a key question, which will be crucial in the definition and implementation of both urban and social policies. This chapter focuses on this phenomenon in the Italian Metropolitan Area of Palermo. We use individual data for all the population residing in the city on 31 December 2011, organised by ethnicity and neighbourhood to describe the spatial distribution and the residential segregation of foreigners in the city, applying many different segregation measures. Results show that the top ten nationalities in Palermo are not uniformly spread across the different parts of the city but tend to cluster in specific areas. The most segregated …
