Last year saw the 10th anniversary of the Workflow Reference Model. This short paper reassesses the relevance of the Model in the current context of Business Process Management. It discusses the principles behind the Model, its strengths and weakness and examines how it remains relevant to the industry today. It concludes by introducing a number of considerations required to establish a “BPM Re...

This report presents the requirements for the MAIS (Multichannel Adaptive Information Systems) reference model. In particular, it is composed by the following models: the architectural model, to describe device components used to access services, the behavior of each component and how they interact with each other; the functional model, to describe the services and related contents, according t...

A Protocol Reference Model is an abstraction of the communication subsystem of a system. Thus, it is appropriate to focus on the protocol reference model when examining the issue of secure communications. In this paper, we discuss some issues in incorporating security services into a protocol reference model. The security services considered are authentication, con dentiality, integrity and acc...

This article presents the elements of model reference adaptive control, which refers to a particular control procedure for uncertain dynamic systems. The control problem as well as the adaptive control problem are described. The use of various models for control, including identification model and reference model is presented. The model-following in the presence of various inputs is discussed. ...

We consider policies that manage fixed-size dynamic linear lists, when the references follow the independent reference model. We define the counter scheme, a policy that keeps the records sorted by their access frequencies, and prove that among all deterministic policies it produces the least expected cost of access, at any time.

The primary goal of NEESgrid data/metadata effort is to work collaboratively with NEESgrid System Integrator team and the NEES community and to help define data requirements and needs for the George Brown Jr. Network for Earthquake Engineering Simulation instigated by the National Science Foundation. The NEESgrid promotes NEES as a distributed virtual laboratory for earthquake engineering resea...
