Zhou, Shuyi. M.S.M.E., Purdue University, December 2017. Experimental and Numerical Study on Microbubble Coalescence Dynamics. Major Professor: Likun Zhu. This thesis work aims to make a better knowledge on the insights of physics on microbubble coalescence process, using experimental and numerical approaches. The neck growth and bubble surface wave propagation at the early stage of coalescence...

We study a process where balls are repeatedly thrown into n boxes independently according to some probability distribution p. We start with n balls, and at each step all balls landing in the same box are fused into a single ball; the process terminates when there is only one ball left (coalescence). Let c := P j p 2 j , the collision probability of two fixed balls. We show that the expected coa...

The coalescent properties of ZnO clusters were studied through experiment and molecular dynamics simulation in combination with the tightbinding potential and ZnO potential. The results from the simulation show that the linearly relationship between the melting temperature and the function of atom numbers of N was obtainable. Extrapolating the result yield at a melting point of 2130 K for N/N (...

The following distributed coalescence protocol was introduced by Dahlia Malkhi in 2006 motivated by applications in social networking. Initially there are n agents wishing to coalesce into one cluster via a decentralized stochastic process, where each round is as follows: every cluster flips a fair coin to dictate whether it is to issue or accept requests in this round. Issuing a request amount...

Gene tree reconciliation problems invoke the minimum number of evolutionary events that reconcile gene evolution within the context of a species tree. Here we focus on the deep coalescence (DC) problem, that is, given an unrooted gene tree and a rooted species tree, find a rooting of the gene tree that minimizes the number of DC events, or DC cost, when reconciling the gene tree with the specie...

An experiment is presented which succeeds for the first time in stimulating the formation of coarse plates of bainite by the coalescence of identically oriented individual platelets. Transformation under the influence of a tensile stress dramatically promotes the formation of the coalesced bainite by increasing the probability of growing parallel platelets in close proximity. Whereas the coarse...

We show that hadronization via quark coalescence enhances hadron elliptic flow at large p(perpendicular) relative to that of partons at the same transverse momentum. Therefore, compared to earlier results based on covariant parton transport theory, more moderate initial parton densities dN/deta(b=0) approximately 1500-3000 can explain the differential elliptic flow v(2)(p(perpendicular)) data f...
