We present the architecture of UbiData an adaptable framework for mobile computing information dissemination systems. Applications built upon this framework communicate using dynamic channels, an information push model with extensions to capture mobilityspecific requirements. We also introduce the development process for UbiData’s applications.

We examine the effect of variability on the performance of an assembly system where two stations feed another station and a competing system where two independent stations are fed by a single station. We study the impact of variability in processing times, variability due to unreliable workstations, and variability due to imperfect yield. The above impact is examined for both PUSH and PULL manu...

Beneath the unconventional allure of hydroponic crops and a floating jungle, Cedric Price’s proposal for Glasgow’s River Clyde banks (1970) is founded on profound concept “design infrastructure”. This article unpacks concept, which intertwined theories ecological subjectivation, human behavior, sensory experience within urban planning discourses. In an era increasingly geared towards da...

In this rebuttal, I will provide an empirically supported deconstruction of Dan’s primary lines of reasoning, in order to assess the validity of his underlying assumptions. My goal in presenting this counter-perspective is not to push back against Dan (in fact, I appreciate the discussion he has stimulated as a “devil’s advocate”), but rather to give fellow advisors a framework for assessing th...

A two-parameter family discrete-time exactly-solvable reaction-diffusion processes on a one-dimensional lattice is introduced, which contains the asymmetric simple exclusion process and the drop-push model as particular cases. The reaction is rewritten in terms of boundary conditions, and the conditional probabilities are calculated using the Bethe-ansatz. This is the discrete-time version of t...

this paper addresses an experimental investigation in the hydrodynamic behavior of a modified slotted sieve tray. slotted sieve tray (push valve sieve tray) is a sieve tray that the push valves have been utilized on the tray deck to eliminate liquid gradients and non-uniformity of liquid distribution on the tray. the air-water system was used in an industrial scale experimental rig with an inte...
