Considering the current state of the art in cloud computing and virtualization, we are at a point in time in which one can develop complex elastic cloud systems. Such systems can have components/units hosted in virtual containers, inside virtual machines, using different cloud offerings (from IaaS to SaaS), potentially from multiple cloud providers. However, to build such systems, and manage th...

Firms with private information about the outcomes of production under uncertainty may face capital (liquidity) constraints that prevent them from attaining efficient levels of investment in a world with costly and/or imperfect monitoring. As an alternative, we examine the efficiency of a simple pooling scheme designed to provide a public (cooperative) supply of liquidity that results in the fir...

Traditional hardware-based firewall appliances are placed at fixed locations with fixed capacity. Such nature makes them difficult to protect today’s prevailing virtualized environments. Two emerging networking paradigms, Network Function Virtualization (NFV) and Software-Defined Networking (SDN), offer the potential to address these limitations. NFV envisions to implement firewall function as ...

As multiple types of distributed, heterogeneous cloud computing environments have proliferated, cloud software can leverage diverse types of infrastructural, platform and data resources with different cost and quality models. This introduces a multidimensional elasticity perspective for cloud software that would greatly meet changing demands from the user. However, we argue that current techniq...

Providers are incorporating novel techniques to cope with prospective aspects of trading like resource allocation over future demands and its pricing elasticity that was not foreseen before. To leverage the pricing elasticity of upcoming demand and supply, we employ financial option theory (future contracts) as a mechanism to alleviate the risk in resource allocation over future demands. This s...

This paper seeks further evidence on the elasticity of calorie demand with respect to household resources. The case presented is for urban areas of Papua New Guinea, where just over one-half of the population appear to obtain less than the recommended amount of dietary energy. The relationship between per capita calorie consumption and per capita expenditure in urban areas of Papua New Guinea i...

Since the pioneering work by Treloar, many models based on polymer chain statistics have been proposed to describe rubber elasticity. Recently, Alicandro, Cicalese, and the first author rigorously derived a continuum theory of rubber elasticity from a discrete model by variational convergence. The aim of this paper is twofold. First we further physically motivate this model, and complete the an...
