We present a scheme for generating new valid inequalities for mixed integer programs by taking pairwise combinations of existing valid inequalities. Our scheme is related to mixed integer rounding and mixing. The scheme is in general sequence-dependent and therefore leads to an exponential number of inequalities. For some important cases, we identify combination sequences that lead to a managea...

background: ocsillator system is recognized by many water plant treatment designers for having many advantages, such as combination of mixing processes, flocculation and sedimentation processes in the same unit, the possibility of softening and lucidity simultaneously, and relatively acceptable efficiency. despite using this process in number of the regions in the country, enough researches hav...

[1] Different turbulent entrainment‐mixing processes (e.g., homogeneous and inhomogeneous) occur in clouds; accurate representation of these processes is critical for improving cloud‐related parameterizations in large‐scale models, but poorly understood and quantified. Using in situ aircraft observations over the U. S. Department of Energy's Atmospheric Radiation Measurement Southern Great Plai...

Mixing time of a Markov chain depends on the eigenvalues of its transition matrix. We give some examples and bounds on the mixing time in terms of the eigenvalue having second largest absolute value. This paper is based on Chapters 1, 4, and 12 of [1].

to assess the effect of time and temperature (in the pumice mixing phase of olive oil extraction) on the quantity and quality features of the extracted oil, a series of experiments comprised of three levels of mixing time (10, 20, and 30 min), and three levels of mixing temperature (30, 45, and 60°c) were carried out. the recorded data were analyzed in the framework of a randomized complete blo...
