Effect of Active Control on Closely Spaced Natural Frequencies
Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure...
Full Scale Application of Active Bracing Systems
A full scale active bracing system has been installed in a structure in Tokyo, Japan. The practical problems associated with the implementation of this system, and the corresponding solutions...
Interaction Effects in the Hybrid Control of Euler-Bernoulli Beams
The effect of viscous and Voigt damping upon the open loop response of simple continua such as Euler-Bernoulli beams is well understood. However, when attempting to control a distributed...
Recent Findings in Active Structural Control

Structural Control Under Stochastic Seismic Loads
This paper presents a method of controlling nonlinear and hysteretic civil engineering structures subjected to stochastic earthquake ground excitations. Emphasis is placed on control of...
Performance-Based Evaluation of Lunar Base Construction Equipment and Methods
Existing literature regarding the selection of lunar base construction equipment and methods is heavily dependent upon qualitative measures for evaluation of equipment concepts. Selection...
Modular Robot Testbed
One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at...
Architectures for Mission Control at the Jet Propulsion Laboratory
One of the most vital, but often overlooked, research areas for space missions is flight operations. The imbalance is caused by many factors. Among them, the manner in which space missions...
Thermal Investigation of a Large Lunar Telescope
Recent interest in construction of a large telescope on the Lunar surface (Nein and Davis, 1991; Bely, Burrows, and Illingworth, 1989) has prompted this feasibility study of a thermal...
The Design and Use of Flow-Through Hold Pads
The Chicago Delay Task Force recommended the construction of nine largescale, flow-through hold pads at Chicago O'Hare International Airport to reduce the potential for airfield gridlock....
Fine Tuning the Airfield: The New Denver International Airport
This paper discusses airfield layout considerations that have been incorporated into the design of the new Denver International Airport (DIA). These concepts include some unique provisions...
The New Munich Airport?Planning, Construction and Opening of a New International Turnstile Airport in Europe
The new Munich airport that began operations just recently dates back to the mid-1950. The paper discusses the general expansion plan which includes site selection; runway system planning;...
Soft Touch People Mover Central Control
The people mover central control systems perform many automatic functions, are built with off-the-shelf redundant hardware, include advanced color graphics and touch screen operator interfaces,...
Baggage System Implementation at DIA
BAE Automated Systems is currently under contract to supply the complete, Integrated Automated Baggage Handling System (IABHS) for the New Denver International Airport. The system represents...
Planning and Budgeting for FAA Facilities and Equipment
Establishing new Federal Aviation Administration (FAA) facilities and equipment (F&E) requires long lead-time planning and through processing in a three-year budget cycle to achieve...
Impact of the New Denver Airport on the Air Traffic Control System
Building the new Denver Airport has two major impacts on air traffic control: first, it requires redesigning the airspace surrounding the Denver area; and second, it requires moving to...
The Airport Traffic Control Tower for the New Denver International Airport
Developing a new airport traffic control tower involves many complexities of planning, engineering, and coordination. For the ATCT at the New Denver International Airport, these complexities...
Traffic Data Collection: What Really Needs to be Done?
The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
The Foundation for a Successful Traffic Impact Analysis
