    Estimating Optimal Cost of Allocating Virtualized Resources With Dynamic Demand

    Data centers are designed to provision sufficient virtualized resources at all times to meet the demands of users. Now-a-days the users who have "Elastic demand" take advantage of the "Pay-as-you-go" model and only request needed demands which vary over time. Considering the dynamics of the demand on virtualized resources is...

    A Deformable Modeling Paradigm for 3D Shape Recovery From Visual Inputs

    In this paper, the authors propose a deformable modeling paradigm for 3D shape recovery from visual inputs such as volumetric data and 3D point clouds. The new model is capable of automatically evolving its shape to capture the geometric boundary of the data and simultaneously discover its underlying topological structure....

    Endogenous Credit Cycles

    The authors study models of credit with limited commitment, which implies endogenous borrowing constraints. They show that there are multiple stationary equilibria, as well as non-stationary equilibria, including some that display deterministic cyclic and chaotic dynamics. There are also stochastic (sunspot) equilibria, in which credit conditions change randomly over time,...
