Intelligent Control Of Vehicles: Preliminary Results On The Application Of Learning Automata Techniques To Automated Highway System, Cem Unsal, John S. Bay, Pushkin Kachroo Nov 1995

Intelligent Control Of Vehicles: Preliminary Results On The Application Of Learning Automata Techniques To Automated Highway System, Cem Unsal, John S. Bay, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

We suggest an intelligent controller for an automated vehicle to plan its own trajectory based on sensor and communication data received. Our intelligent controller is based on an artificial intelligence technique called learning stochastic automata. The automaton can learn the best possible action to avoid collisions using the data received from on-board sensors. The system has the advantage of being able to work in unmodeled stochastic environments. Simulations for the lateral control of a vehicle using this AI method provides encouraging results.


Resource Use Conflict In New York City's Catskill Watersheds: A Case For Expanding The Scope Of Water Resource Management, Krystyna Anne Stave Apr 1995

Resource Use Conflict In New York City's Catskill Watersheds: A Case For Expanding The Scope Of Water Resource Management, Krystyna Anne Stave

Public Policy and Leadership Faculty Publications

In New York City's water supply watersheds, controversy over water quality protection underscores both the need to expand the scope of water resource management and the challenges to doing so. This paper describes the response of watershed residents to !'Jew York City's efforts to avoid filtration mandated by the 1986 Safe Drinking Water Act Amendments and 1989 Surface Water Treatment Rule. The emergence of a spectrum of stakeholder groups representing land owners, sport fishermen, businesses, environmental groups and local communities has brought social and economic issues not previously part of the City's water management program to the center of the …


Limiting Growth In Las Vegas - A Necessary Growth Strategy For The Twenty-First Century, Cheryl Ann Frassa Apr 1995

Limiting Growth In Las Vegas - A Necessary Growth Strategy For The Twenty-First Century, Cheryl Ann Frassa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Land development in the Las Vegas Valley continues at an unprecedented rate and future growth will no doubt be strongly advocated. Yet, water resources in this desert area are finite, and in the near future, supply will fall short of demand. Plans are underway to supplement the existing supply, and proposals to secure additional sources are under investigation. But there are no guarantees these ambitious endeavors will materialize. In light of the pending water crisis, the pervasive "growth at all cost" policies now dominant in the valley must be abandoned and more realistic land-use policies developed; ones based on the …


Updating The Colorado River Compact, Jeffrey A. Freer Apr 1995

Updating The Colorado River Compact, Jeffrey A. Freer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Water is essential to life in the arid environment of the western United States. For centuries, humans have used the Colorado River to fulfill their needs and until the past 100 years, the use of the river was sustainable. Over the last 100 years, the Colorado River has been dammed and diverted to "reclaim" the arid west for man's use. In 1946, a Department of the Interior report stated that "Tomorrow the Colorado will be utilized to the very last drop. Its water will convert thousands of additional acres of sagebrush desert to flourishing farms and beautiful homes for servicemen, …


Using Gis To Identify Critical Areas For Water Quality Protection In New York City's Water Supply System, Paul K. Barten, Krystyna Anne Stave Apr 1995

Using Gis To Identify Critical Areas For Water Quality Protection In New York City's Water Supply System, Paul K. Barten, Krystyna Anne Stave

Public Policy and Leadership Faculty Publications

The protection of water quality at its source — the watershed — recognizes that minimizing land use impacts and allowing natural processes to provide in situ biological treatment can complement conventional engineering methods. In contrast to the enormous costs projected for drinking water filtration, the judicious application of watershed management principles and practices is a way to balance the needs of people with the capacity of the natural resource base over time. This paper describes the development and initial application of a geographic information system (GIS) to a ortion of New York City's 2,000 square mile water supply system, the …
