Parameters of walkability: A meta-analysis
(2018)Walkability can be understood as the walk-friendliness of a built environment. A wide range of walkability attributes are reported and measured in existing literature. However, a consensus on the relative importance of each parameter does not exist. General models for the interactions between pedestrians and their environment have only been suggested in a rudimentary form. To address these issues, an in-depth research of the relevant ...Working Paper -
Propagation of moments in Hawkes networks
(2018)arXivThe present paper provides a mathematical description of high-order moments of spiking activity in a recurrently-connected network of Hawkes processes. It extends previous studies that have explored the case of a (linear) Hawkes network driven by deterministic rate functions to the case of a stimulation by external inputs (rate functions or spike trains) with arbitrary correlation structure. Our approach describes the spatio-temporal ...Working Paper -
Thermocapillary-driven fluid flow within microchannels
(2018)arXivSurface tension gradients induce Marangoni flow, which may be exploited for fluid transport. At the micrometer scale, these surface-driven flows can be more significant than those driven by pressure. By introducing fluid-fluid interfaces on the walls of microfluidic channels, we use surface tension gradients to drive bulk fluid flows. The gradients are specifically induced through thermal energy, exploiting the temperature dependence of ...Working Paper
