Mismatch capacity per unit cost
The mismatch channel capacity per unit cost represents the maximum number of bits per unit cost that can be transmitted reliably across a channel under receiver mismatch conditions. It's reciprocal is the minimal cost of transmitting a bit reliably under these conditions. We derive lower bounds for …

Development of unit cost database to estimate costs for utility relocation projects
… timely delivery of infrastructure projects, and cost overruns. Despite being recognized as an impeding factor to project delivery, there is no ready-to-use cost database or software platform available for estimating the relocation costs of different utilities. This thesis aims to collect, analyze …

Production and cost analysis of two harvesting systems in central Appalachia
Cost and productivity are major factors when considering which type of harvesting system to operate. Observations were conducted on manual and mechanized harvesting operations in central Appalachian hardwood forest sites in order to obtain time study data. Production and cost analysis were …

Parametric cost estimation utilizing development-to-production cost relationship applied to the advanced amphibious assault vehicle
… examines the relationship between development unit cost and production unit cost. Historical data from seven armored tracked vehicle programs is used to test the relationship. A study of this relationship is useful when production has not begun and the estimator wants a means to estimate …

The evolution of U.S. airlines' productivity and cost performance from 2004-2012
… carriers implemented drastic measures to reduce cost and increase productivity. Some filed bankruptcy protection to restructure, and others pursued mergers for consolidation and cost savings through operational synergies. Low cost carriers have been profitable but are now faced with higher costs …
