This paper examines how speed shapes internet culture. To do so, it analyses ‘memetic moments’ on Twitter, short-lived and rapidly circulated memes that quickly reach saturation. The two Twitter in 2018 2019 to assess they develop over time. Each case study comprises a week’s worth of relevant tweets were analysed for temporal patterns. We analyse these through Lefebvre’s (2004) work rhythmanal...

Decaying two-dimensional turbulence is characterized by the emergence of coherent vortices, which’subsequently dominate the evolution. The temporal scaling behavior of the flow is analyzed using a scaling theory, a long-time integration of the fluid equations, and a dissipative, modified point-vortex model that represents the turbulence as a system of interacting coherent structures. Good agree...

Beginning with stochastic formulation [1] of transport phenomena in terms of a continuous-time random-walk (CTRW), the physical community showed a steady interest in the anomalous diffusion, i.e., a diffusion that appears in absence of the second/first moments of the spatio-temporal random-walk jump parameters and with scaling different than that of the classical Gaussian diffusion. Such an att...

This paper proposes a way of incorporating fuzzy temporal reasoning within diagnostic reasoning. Disorders are described as an evolving set of necessary and possible manifestations. Fuzzy intervals are used to model ill-known moments in time (e.g. the beginning and end of a manifestation) and intensity of manifestations (e.g. "high" fever). The paper discusses several measures of consistency be...

The multifractal structure of the temporal dependence of the Deutsche Aktienindex (DAX) is analyzed. The q-th order moments of the structure functions and the singular measures are calculated. The generalized Hurst exponent H(q) and the h(γ(q)) curve indicate a hierarchy of power law exponents. This approach leads to characterizing the nonstationarity and intermittency pertinent to such financi...

In this paper we present BTC, which is a logic for branching-time whose modal operator quantifies over histories and temporal operators involves a restricted quantification over histories in a given possible choice. This is a technical novelty, since the operators of the usual logics for branching-time such as CTL expresses an unrestricted quantification over histories and moments. The value of...
