The appearance of new forms of inhabiting the space has emerged to meet citizens' demands and new business paradigms. The contemporary city embraces a postmodern concept. The outcome is a new biopolitical project that affects citizens' living conditions th ...
La ville de Porto a subi une évolution radicale ces 10 dernières années. L’essor du tourisme ainsi que la spéculation immobilière ont fait que le prix d’un loyer ne correspond plus à la réalité économique portugaise. Entre l’éviction des classes sociales m ...
When a mixture of particles, which differ in both their size and their density, avalanches downslope, the grains can either segregate into layers or remain mixed, dependent on the balance between particle-size and particle-density segregation. In this pape ...
A general continuum theory for particle size segregation and diffusive remixing in polydisperse granular avalanches is formulated using mixture theory. Comparisons are drawn to existing segregation theories for bi-disperse mixtures and the case of a ternar ...
Security discourses taking place in contemporary cities – in both developing and developed countries – feed defiance and legitimize an “urbanism of fear” based on controls that increase social and spatial segregation. Inversely, a sustainable city is an in ...
An ordered segregation requires distinct processes of differentiation within the germ cell for recognition and segregation of homologous chromosomes/chromatids. These include synchronous maturation of the nucleus and cytoplasm, chromosome pairing and assem ...
We study a simple algorithm inspired by the Brazil nut effect for achieving segregation in a swarm of mobile robots. The algorithm lets each robot mimic a particle of a certain size and broadcast this information locally. The motion of each particle is con ...
