CALCULATION OF OIL CONTAINMENT BOOM SCREEN AGAINST WAVE IMPACT

Rural North Dakota's oil boom and its impact on social services.

Over the last five years, North Dakota has experienced an oil boom based on high oil prices and hydraulic fracturing technologies. This has brought economic expansion and population growth to rural communities that had previously experienced decades of depopulation and economic struggle. Although the state has enjoyed many benefits--especially in juxtaposition to a sluggish national economy--th...

Screen-Parallel Calculation of Surface Intersections

When surfaces intersect, one may desire to highlight the intersection curve in order to make the shape of the penetrating surfaces more visible. Highlighting the intersection is especially helpful when the surfaces become transparent, because transparency makes the intersections less evident. This paper discusses a technique for locating intersections in screen space using only the information ...

Investor Flows and the 2008 Boom/Bust in Oil Prices

This paper explores the impact of investor flows and financial market conditions on returns in crude-oil futures markets. I argue that informational frictions and the associated speculative activity may induce prices to drift away from “fundamental” values, and may result in booms and busts in prices. Particular attention is given to the interplay between imperfect information about real econom...

Propellant Containment Utilizing Screen Mesh and Perforated Plate Surfaces

The Impact of Virtual Views on Containment

Virtual views are a mechanism that facilitates re-use and makes queries easier to express. However the use of iterative view definitions makes very simple query evaluation and analysis problems more complex. In this paper we study classical containment and equivalence problems for queries built up through simple unions of conjunctive queries and view definitions. More precisely, we determine th...
