Coalescence is the problem of isolated mobile robots independently searching for peers with the goal of forming a single connected network. This paper analyzes coalescence time for a worst-case scenario where the robots do not have any knowledge about the environment or positions of other robots and perform independent, memoryless search. Using the random direction mobility model, we show that ...

Coalescence is an essential phenomenon that governs the equilibrium behaviour in a variety of systems from intercellular transport to planetary formation. In this report, we study coalescence pathways of circularly shaped two-dimensional colloidal membranes, which are one rod-length-thick liquid-like monolayers of aligned rods. The chirality of the constituent rods leads to three atypical coale...

in this investigation, the mechanical properties of the blends of blown bitumen110/10, heavy vacuum slops (h.v.s), bitumen 60/70 penetration grade and isotactic polypropylene (ipp) were studied for the first time. our results showed that modulus varies non-linearly and at certain asphaltenes contents a peak appears. considering these phenomena it is revealed that in the absence of ipp, interact...

Coalescence frequency and lifetimes of thin aqueous films formed between nitrogen bubbles were measured in dilute solutions of sodium lauryl suitate, «-amyl alcohol, and 1-butanol. The bubble pairs were formed on two adjacent capillary tubes by use of a microprocessor-controlled stepping motor, and the coalescence time was determined by an optical sensing method. For low-molecular weight alcoho...

We present the results of a combined experimental and theoretical study of drop coalescence in the presence of an initial temperature difference 1T0 between a drop and a bath of the same liquid. We characterize experimentally the dependence of the residence time before coalescence on 1T0 for silicone oils with different viscosities. Delayed coalescence arises above a critical temperature differ...

Abstract—We report in this paper the evolution of a physically based drop size distribution coupling the Maximum Entropy Formalism and the Monte Carlo method to solve the coagulation equation. Using the discrete or continuous population balance equation, the Mass Flow Algorithm is formulated taking into account interactions between droplets via coalescence. After proposing a kernel for coalesce...
