In 1957, the Navy’s Special Projects Office approached APL for assistance in developing the Polaris Fleet Ballistic Missile (FBM) Strategic Weapon System. The primary task was to define and execute a comprehensive FBM test and evaluation program to validate the integrated weapon system design. The launch of Sputnik created a widespread view that a “missile gap” existed with the Soviet Union. In...

This paper presents a four-faceted framework for distributed applications that use worldwide networks connecting large numbers of people, software tools, monitoring instruments, and control devices. We describe a class of applications, identify requirements for a framework that supports these applications, and propose a design fulfilling those requirements. We discuss some initial experiences u...

We give a new randomized algorithm for achieving consensus among asynchronous processes that communicate by reading and writing shared registers. The fastest previously known algorithm, due to Abrahamson, has expected running time 2°^\ Our algorithm is polynomial, requiring an expected 0 ( n 4 ) operations. Applications of this algorithm include the elimination of critical sections from concurr...

Wildlife Service to supply scientific information and methodologies on key environmental issues that impact fish and wildlife resources and their supporting ecosystems. Projects have been initiated in the following areas: coal extraction and conversion; power plants; mineral development; water resource analysts, including stream alterations and western water allocation; coastal ecosystems and O...

Population supports the need for switching to green power, which is most often understood mean use of solar and wind energy. It would be however a mistake think that power plants will solve in full problem uninterrupted supply all sectors economy due instability generation modes scale such energy production. Experts suggest only possible way address global environmental issues further evolution...

We introduce our extensive projects on spontaneous speech processing and current trials of lecture speech recognition. A large corpus of lecture presentations and talks is being collected in the project. We have trained initial baseline models and confirmed significant difference of real lectures and written notes. In spontaneous lecture speech, the speaking rate is generally faster and changes...
