Policy Synthesis for Collective Dynamics [chapter]

Paul Piho, Jane Hillston
2018 Lecture Notes in Computer Science  
To combat this we propose an approach exploiting the results on fluid approximations of continuous time Markov chains to obtain estimates of optimal policies.  ...  In this paper we consider the problem of policy synthesis for systems of large numbers of simple interacting agents where dynamics of the system change through information spread via broadcast communication  ...  of the fluid approximation.  ...

Broadcast Disks with Polynomial Cost Functions

Amotz Bar-Noy, Boaz Patt-Shamir, Igor Ziper
2004 Wireless networks  
Finally, we study the quality of approximating the greedy schedule by a finite schedule.  ...  The fundamental algorithmic problem for such systems is to determine the broadcast schedule based on the demand probability of items, and the cost incurred to the system by clients waiting.  ...  The motivation for considering the fluid model is twofold. First, it can serve as a faithful abstraction of certain physical systems.  ...

Furthermore, under mild assumptions, we find that the optimal policy for the stochas- tic model is closely approximated by an affine shift of the fluid optimal solution.  ...  If this condition does not hold, then the ‘gap’ between the fluid and stochastic optimal policies is exactly proportional to system variability.  ...

Shannon Meets Fick on the Microfluidic Channel: Diffusion Limit to Sum Broadcast Capacity for Molecular Communication

A. Ozan Bicen, Janne J. Lehtomaki, Ian F. Akyildiz
2018 IEEE Transactions on Nanobioscience  
The convergence of the sum capacity for microfluidic broadcast channel is analytically investigated based on the physical system parameters with respect to the increasing number of molecular receivers.  ...  Although the use of different types of molecules provides orthogonal signaling, the sum broadcast capacity may not scale with the number of the receivers due to physics of the propagation (interplay between  ...  The provided analysis of sum broadcast capacity may help to predict the performance of the multi-sample chemical analysis systems on a microfluidic chip.  ...

Streaming: A Media Hydrography of Televisual Flows

Ghislain Thibault, Mediarep.Org
2020 VIEW Journal of European Television History and Culture  
This paper situates the metaphor of 'streaming' in contrast to and connection with fluid analogies and metaphors that have been used to describe different models of media transmission.  ...  From the early use of aqueous vocabulary that shaped popular and scientific understandings of electricity transmission to the seminal studies of mass communication concerning the flows of information,  ...  Unlike broadcasting, however, where networks could only monitor individual consumption through statistical approximation, 29 streaming minutely tracks the volume of data consumed by the users.  ...
