Moving is a tricky business. UI seniors Dave Sherlock and Gregor Ernst were moving out of Ralston Creek apartments Monday afternoon, and Ernst said the move across town was a race with the clock. "I can't move into (my new apartment) until 12 p.m., but I have to be completely moved out of here by 2;20 p.m.," he said. "Some of my friends and I rented a truck for $90." Thousands of Iowa city resi...

This work presents several approaches for designing the memory management component of self-stabilizing operating systems. We state the requirements a memory manager should satisfy. One requirement is eventual memory hierarchy consistency among different copies of data residing in different (level of) memory devices e.g., RAM and Disk. Another requirement is stabilization preservation a conditi...

In Prince Edward Island (PEI), shellfish (bivalves comprised of mussel and oyster) aquaculture production occurs in sheltered, generally shallow bays. The productive capacity of a bay for shellfish aquaculture is determined by many factors including the hydrodynamics of the bay and input of nutrients. There is considered to be a limit to the production (biomass) that can be extracted from an ar...

Most oil and gas leases allow the operator to extend possession for an indefinite period by establishing production in paying quantities. We show how this option to “hold by production” (HBP) stimulates the drilling of many wells that would otherwise be uneconomic. Although such wells may superficially appear to be poor investments, in fact they contribute to shareholder value. We also show, ho...

This paper studies federal auctions for wildcat leases on the Outer Continental Shelf from 1959 to 1970. These are leases where bidders privately acquire (at some cost) noisy, but equally informative signals about the amount of oil and gas that may be present. We develop a test of equilibrium bidding in a common values model that is implemented using data on bids and ex post values. We compute ...

Clouds can be used to provide on-demand capacity as a utility. Although the realization of this idea can differ among various cloud providers (from Google App Engine to Amazon EC2), the most flexible approach is the provisioning of virtualized resources as a service. These virtualization-based clouds, like Amazon EC2 or the Science Clouds (which uses the Globus Virtual Workspace Service [4]), p...

The Witwatersrand Basin contains by far the most gold ever found, and has hosted mining from its discovery in 1886 to present. For many years, South Africa was world's largest producer of gold, nearly all which came Witwatersrand. Since 2000, fallen back several positions because declining output. There are complex varied reasons for this; however, resources not one them. As as author knows, th...
