We consider the continuity equation with a nonsmooth vector field and a damping term. In their fundamental paper, DiPerna and Lions (Invent Math 98:511-547, 1989) proved that, when the damping term is bounded in space and time, the equation is well posed i ...
The main topic of this presentation is the justification of the interview protocol developed in my doctoral research, a research that studies the collective representations of what a just space is, for the city-society of the Metropolitan Area of Porto. Th ...
The last quarter of a century has seen a dramatic rise of interest in the spatial constraints on multisensory integration. However, until recently, the majority of this research has investigated integration in the space directly in front of the observer. T ...
Although treatment for cholera is well-known and cheap, outbreaks in epidemic regions still exact high death tolls mostly due to the unpreparedness of health care infrastructures to face unforeseen emergencies. In this context, mathematical models for the ...
Explore how geography, cartography, urbanization and spatial justice play a role in shaping the notion of human space. An introduction to geographicity proposed by Chôros on edX platform ...
The accuracy of state estimators using the Kalman Filter (KF) is largely influenced by the measurement and the process noise covariance matrices. The former can be directly inferred from the available measurement devices whilst the latter needs to be asses ...
It is commonly accepted that mobility of people, especially of highly-skilled workers, has acquired a much more temporary character. Such fluid patterns of mobility call to attention the need to observe in what way highly-skilled migrants at present relate ...

The paper demonstrates a phase estimation method in fringe analysis. The proposed method relies on local polynomial phase approximation and subsequent state-space formulation. The polynomial approximation of phase transforms phase extraction into a paramet ...
The modern expressions for polarization P and orbital magnetization M are k-space integrals. But a genuine bulk property should also be expressible in r space, as an unambiguous function of the ground-state density matrix, "nearsighted'' in insulators, ind ...
