A series of direction determination experiments has been performed to evaluate the extent to which automobile drivers can locate audible warning devices of emergency vehicles. Blindfolded subjects were required to indicate the perceived position of a siren, first in an open space and, secondly, while seated in an idling automobile with the windows both open and closed. For the open-air control case, the direction of the siren was correctly indicated to be in the appropriate 45° sector for 91% of the test presentations. With the subject seated in the automobiles, the identification of the correct location fell to 37.6% with the passenger window open and 26% with the windows closed. Based on an analysis of the results and the magnitude of the errors, it is concluded that aural localization for the directional identification of emergency vehicles is not practicable.

Early in 2005 General Electric Water & Process Technologies (GE) began supplyingCraftMaster Manufacturing, Inc. (CMi) with water treatment chemicals and expertise. A GE/CMi team, composed of operations, technical and management personnel, was established to uncover and address immediate and long term wastewater system problems and issues. The combination of experience and troubleshooting expertise allowed for collaborative work to continuously improve operations, increase reliability and reduce overall costs.
OVERVIEW OF WASTEWATER TREATMENT PROCESSThe main wastewater treatment plant consists of screening, primary and secondary treatment operations, and dewatering. CMi processes 1 -1.5 MGD (158 -237 m 3 /hr) of mill process wastewater and storm runoff water. Figure 1 shows a general schematic of the wastewater treatment system and recycle loop. CraftMaster operates a "zero wastewater discharge" system. Wastewater is treated, then stored in lagoons for recycle to the mill as makeup process water. Some water is purged to sprayers to irrigate fields.
Antitrust and the Future of the Connected World Under ObamaThis paper aims to serve as a preliminary background for computer lawyers considering some of the issues involved when networked communications, information and computer systems and related intellectual property are considered in an antitrust context. The box of antitrust, with its constrained view of the world and inability to understand the world as it has changed in a hundred years apart from time-tested and outdated thinking embedded in decades of US antitrust cases, is constrained by ossified competition law, intellectual property and economic thinking despite the vast changes in our world since the introduction of the Internet. During its thirty year dormancy (according to some), antitrust leaned away from enforcement and toward strong intellectual property rights, withstanding a variety of challenges as the world moved from the written to the digital word, from information limits to unlimited information, from old to new technologies, from delayed to immediate communications.We are now at a crossroads in antitrust and competition law enforcement. Apart from per se offenses like horizontal price fixing and bid rigging, for which damage is certain, industry-wide and economy-wide studies are essential if we are not to upset our currently efficient systems in favor of some new unknown. For many reasons, antitrust "change" under Obama provides an opportunity for a better and more comprehensive vision of the interfaces involved in the Internet, computer systems and competition. The systems and issues discussed above warrant consideration of new perspectives and renewed understanding of the ways in which antitrust laws affect innovation and markets.
