In an Infrastructure as a Service (IaaS), the amount of resources allocated to a virtual machine (VM) at creation time may be expressed with relative values (relative to the hardware, i.e., a fraction of the capacity of a device) or absolute values (i.e., a performancemetric which is independent from the capacity of the hardware). Surprisingly, disk or network resource allocations are expressed...

background: chemical exposure is a major health problem globally. poison control centers (pccs) play a leading role both in developed and developing countries in the prevention and control of poisonous chemical exposures. in this study, we aimed to assess the current state of pccs in pakistan and highlight capacity building needs in these centers. methods: a cross-sectional survey of the two re...

The biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. Efficient utilization of existing infrastructures has a prominent role in response to the challenges. Energy hub approach embraces performance of different energy networks. Energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...

The increasing demand for multimodal freight transportation makes the expansion of new secondary hubs necessary. carbon tax has also received attention from various sectors due to development requirements green transportation. Therefore, this study proposed a transport hub location problem, where emissions are specifically considered achieve strategic planning. A mixed integer non-linear progra...

Abstract We study a variation of the duopoly model by Kreps and Scheinkman (1983). Firms limited their capacity production engage in two stage game. In first they commit to levels not exceeding capacities which are then made common knowledge. second after has taken place firms simultaneously compete prices. Solution this sequential game shows that unique Cournot equilibrium outcome as is always...
