Canonical variate analysis in identification, filtering, and adaptive control
The canonical variate analysis (CVA) approach for system identification, filtering, and adaptive control is developed. The past/future Markov property provides a starting point for defining a reduced-order prediction problem. The solution is a canonical variate analysis that is characterized by a generalized singular value decomposition. State-spac....

Differences between building a traditional DSS and an ODSS: lessons from the Air Force's Enlisted Force Management System
It is shown that, although many aspects of a traditional decision support system (TDSS) and an organizational decision support system (ODSS) are similar, there are important differences that must be understood if the ODSS is to be successful. Differences in purposes lead to differences in design, differences in managing the development effort, diff....

Commutativity-based concurrency control for abstract data types
Two novel concurrency control algorithms for abstract data types are presented. The algorithms ensure serializability of transactions by using conflict relations based on the commutativity of operations. It is proved that both algorithms ensure a local atomicity property called dynamic atomicity. This means that the algorithms can be used in combin....

Nonparametric feature selection for multiple class processes
A method of feature selection is presented that has linear computational complexity, and ways are shown how to use it when the type of the probability density function is unknown. There is no claim that the procedures for nonparametric probability density function estimation are applicable to any thinkable distribution, but the lower bound for the ....

Disk array systems
A description is given of the Strategy 2 Architecture, which consists of a control processor, a large data buffer, direct memory access controllers, disk drive control interfaces, a high-speed FIFO (first-in first-out) interface, and a data-flow processor for data reconstruction and parity. Strategy 2 is an intelligent controller capable of storing....

Using transactions in distributed applications
An extended example is presented to illustrate the use of atomic transactions in implementing distributed programs. It is shown that transactions can be used to control concurrency and recover from failures, making it relatively easy to write programs that access and modify distributed and even replicated data. Type-specific concurrency control tec....

Apprenticeship instruction through adaptive human-computer interaction
Discusses an approach and issues regarding the use of intelligent adaptive user interfaces, coupled with hypermedia, to provide supportive learning situations for users within an instructional paradigm of cognitive apprenticeship. Existing models of user interaction are examined and extended with a supportive learning model of user interaction. The....
