Due to the complexity and variability of capital construction sites, real-time monitoring remains an elusive goal. As unit price continues to fall, camera networks are becoming increasingly viable sensing modalities. The benefits of combining multiple, overlapping image sources include the ability to produce 3D scene reconstruction as well as localize and track objects. In the construction doma...

In recent years, aiming to reduce the Greenhouse Gas pollution and promote energy efficiency and conservation among consumers’ energy use, price policies and price changes derived from environmental regulations have played a more important role. In this paper, using the most recent annual state-level panel data for 48 states, I estimate a dynamic partial adjustment model for electricity demand ...

We study popular local search and greedy algorithms for standard machine scheduling problems. The performance guarantee of these algorithms is well understood, but the worst-case lower bounds seem somewhat contrived and it is questionable whether they arise in practical applications. To find out how robust these bounds are, we study the algorithms in the framework of smoothed analysis, in which...

In 1983 L. E. Jones exhibited a surprising example of a weakly Pareto optimal al­ location in a two consumer pure exchange economy that failed to be supported by prices. In this example the price space is not a vector lattice (Riesz space). Inspired by Jones' example, A. Mas-Colell and S. F. Richard proved that this pathological phenomenon cannot happen when the price space is a vector lattice....

This paper is a quantitatively-oriented theoretical study into the interaction between housing prices, aggregate production, and household behaviour over a lifetime. We develop an overlapping generations model of a production economy in which land and capital are combined into residential and commercial structures. We …nd that, in the economy where land is more important for structures, the hou...

In the literature, the study of price subsidies of new technologies has focused on the tactical problem of achieving maximum penetration under a budget constraint over a short horizon. In practice, such tactical, short-termpenetration objectives seemboth to adequately reflect the structure ofmany price subsidy programs (e.g., solar energy), and account for their high failure rate. The present p...

It is suggested that instead of attempting to adjust the consumer price index (CPI) after tax reform it is better to measure changes in after-tax income.
