Planning Report 02-1: The Economic Impact of Role-Based Access Control
The National Institute of Standards and Technology (NIST) began working on RBAC in the early 1990s after a study of federal agency security needs identified the need to develop a better method for managing large networked systems and complex access issues
Knowledge-Based Automation of a Design Method for Concurrent Systems
This paper describes a knowledge-based approach to automate a software design method for concurrent and real-time systems. The approach uses multiple paradigms to represent knowledge embedded within the design method. Semantic data modeling provides the

Pilot-Assisted 16-Level QAM for Wireless Video
This paper presents a twin-class transmission system for narrowband radio access channels suitable for handheld video phone and multimedia portable PC applications. The transmission system is comprised of a hierarchical 16-QAM modulation technique and a
Foreword for Motohisa Kanda's Special Issue
This special issue of the IEEE EMC Transactions is in honor of Dr. Motohisa Kanda who passed away on June 12, 2000. Dr. Kanda, known to most of us simply as "Moto," was an important figure within the EMC community and served as Editor of the IEEE EMC
Video Transmission for Multi-Hop Networks Using IEEE 802.11 FHSS
In many applications such as construction, manufacturing, ground robotic vehicles, and rescue operations, there are many issues that necessitate the capability of transmitting digital video and that such transmissions should be performed wirelessly and in
Understanding Consistency Maintenance in Service Discovery Architectures in Response to Message Loss
Current trends suggest future software systems will comprise collections of components that combine and recombine dynamically in reaction to changing conditions. Service-discovery protocols, which enable software components to locate available software

Failure Modes in Medical Device Software: an Analysis of 15 Years of Recall Data
Most complex systems today contain software, and systems failures activated by software faults can provide lessons for software development practices and software quality assurance. This paper presents an analysis of software-related failures of medical
Failure Modes in Medical Device Software: an Analysis of 15 Years of Recall Data
Segmentation for Robust Tracking in the Presence of Severe Occlusion
Tracking an object in a sequence of images can fail due to partial occlusion or clutter. Robustness can be increased by tracking a set of parts, provided that a suitable set can be identified. In this paper we propose a novel segmentation, specifically
Video Transmission for Third Generation Mobile Communication Systems
This paper presents a method of transmitting video over the cdma2000 mobile systems. In this method, the video bit-stream, after splitting, is transmitted via the supplemental channels of the cdma2000 reverse link. The method takes advantage of the direct
Underlying Technical Models for Information Technology Security
Underlying Technical Models for Information Technology Security provides a description of the technical foundations, termed models, that underlie secure information technology (IT). The intent is to provide, in a concise form, the models that should be
Segmentation for Robust Tracking in the Presence of Severe Occlusion
Tracking an object in a sequence of images can fail due to partial occlusion or clutter. Robustness can be increased by tracking a set of ¿parts¿, provided that a suitable set can be identified. In this paper we propose a novel segmentation, specifically
Recommendation for Block Cipher Modes of Operation Methods and Techniques
This recommendation defines five confidentiality modes of operation for use with an underlying symmetric key block cipher algorithm: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR)
Predicting Resource Demand in Heterogeneous Active Networks
Recent research, such as the Active Virtual Network Management Prediction (AVNMP) system, aims to use simulation models running ahead of real time to predict resource demand among network nodes. If accurate, such predictions can be used to allocate network
Implementing Message Priority Policies Over an 802.11 Based Mobile Ad Hoc Network
In a mobile ad hoc network (MANET) for military or emergency applications, it is required to give priority to certain messages or message sources. In this paper, mechanisms are considered for implementing priority treatment of packets in a MANET using the
Hybrid Fractal Zerotree Wavelet Image Coding
In this paper, a hybrid fractal zerotree wavelet (FZW) image coding algorithm is proposed. The algorithm couples a zerotree-based encoder, such as the embedded zerotree wavelet (EZW) coder or set partitioning in hierarchical trees, and a fractal image
