Time-frequency localization via the Weyl correspondence

Abstract: A technique for producing signals whose energy is concentrated in a given region of the time-frequency plane is examined. The degree to which a particular signal is concentrated is measured by integrating its time-frequency distribution over the given region. This technique, using the Wigner distribution, has recently been used as a framework for time-varying filtering. The associated subspace projection operator is studied. Estimates for the eigenvalue decay and the smoothness and decay of the eigenfunctions are presented. >

The role of software architecture in requirements engineering

Abstract: The role of software architecture (which reflects high-level implementation constraints) in requirements engineering is clarified by providing perspectives on relevant issues, including the following: is requirements engineering merely a front end to the software development process that is concerned only with problem definition? Is software architecture an application-specific, high-level design of a system (for example, "an object-oriented system with a specified object hierarchy")? What is the relationship between the problem definition and the solution structure? What is the relationship between the roles of requirements engineer, software architect, and application domain specialist?. >

Technology to advance infectious disease forecasting for outbreak management

Abstract: Forecasting is beginning to be integrated into decision-making processes for infectious disease outbreak response. We discuss how technologies could accelerate the adoption of forecasting among public health practitioners, improve epidemic management, save lives, and reduce the economic impact of outbreaks.

Fault tolerance in a systolic residue arithmetic processor array

Abstract: The regularity of systolic arrays and the potential for redundancy in residue number systems are used to provide fault tolerance in VLSI systems. The fault tolerance is concurrent with normal circuit operation and allows a continuous flow of correct data when a fault occurs. There is no interruption of valid data flow while the circuits are reconfigured. The technique also obviates the need for ultrahigh-reliability switches and switching control circuits. A fault-tolerant implementation of a finite-impulse-response filter with five residue channels, two of which are redundant, demonstrates the technique. As long as not more than one cell in each processing block is faulty, the filter outputs contain no errors. >

Method for conducting a moving vehicle along a trajectory of a coordinated maneuver based on state information broadcast by other vehicles participating in the coordinated maneuver

Abstract: A method for coordinating numerous vehicles within a common maneuver is characterized by receiving, at a moving vehicle, state and projected maneuver information of other vehicles participating in the maneuver via a broadcast link and utilizing the information to control the trajectory of the moving vehicle based on predicted paths of all participating vehicles for future times for which the maneuver is to be conducted. For simple maneuvers, such as flight-deck based self-spacing of aircraft in a runway approach, the method allows each participating vehicle to virtually perform the coordinated maneuver by predictive simulation using current state data to determine if corrective measures need be undertaken, or, if the predicted maneuver shows that it would complete as planned, maintaining its current trajectory. This affords vehicle operators the freedom to perform other duties, as the operators are alerted only when a change in state is necessitated. In the runway approach problem, the state changes are primarily in a change of speed and the choice of a simple, stepped speed profile reduces the amount of speed control that must be attended to by aircraft flight crews, allows for fuel efficient flight profiles within constraints of solving the spacing problem, and allows for higher runway throughput as compared with the prior art.
