UML 2 Activity and Action Models, Part 3: Control Nodes

January 1, 2004
Author(s)
Conrad E. Bock
This is the third in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model. The previous article addressed the execution characteristics of actions in general, and

UML 2 Activity and Action Models, Part 4: Object Nodes

January 1, 2004
Author(s)
Conrad E. Bock
This is the fourth in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model [1]. The first article gives an overview of activities and actions [2], while the second two

Uncertainty Due to Finite Resolution Measurements

January 1, 2004
Author(s)
Steven D. Phillips, B Tolman, William T. Estler
We investigate the influence of finite resolution on measurement uncertainty from a perspective of the Guide to the Expression of Uncertainty in Measurement (GUM). Finite resolution in the presence of Gaussian noise yields a distribution of results that

Vector Mixer Characterization for Image Mixers

January 1, 2004
Author(s)
Joel Dunsmore, Sean Hubert, Dylan Williams
The vector mixer characterization method first introduced by Dunsmore [1] can be used only for mixers where the Local Oscillator (LO) frequency lies between the RF input and output frequencies. Attempts to use the method for mixers with the LO greater than

Virtual Surface Calibration Database

January 1, 2004
Author(s)
Thomas B. Renegar, Theodore V. Vorburger, Son H. Bui
This paper presents the development of a virtual surface calibration database for parameter evaluation and algorithm verification. The database runs from a web site at the National Institute of Standards and Technology (NIST), USA. Companies, universities

Virtual Testing of Ready-Mixed Concrete

January 1, 2004
Author(s)
Jeffrey W. Bullard
The development of a virtual testing system is no small task. It requires fundamental scientific research into the physics, chemistry, and materials science of concrete. The Virtual Cement and Concrete Testing Laboratory consortium has identified three
