The CRANIUM: A Case Study of Sensory Improvement for Construction Equipment Operators
Machines excel at physical processes such as generating large forces and performing repetitive motions, but humans are still better at information intensive processes such as planning,...
Computer-Based Environment for Integrated Tunneling Design and Construction
The MIT tunneling group has developed, over the past decade, a number of decision support tools for the geologist and engineer, planner and designer, owner and contractor involved in tunnel...
Globalization and its Impact on Construction Technology
The nature of international construction markets is changing. Competition is yielding to the concept of globalization. This paper discusses some of the issues which constitute topics of...
Computer Data Exchange Using National and International Standards
There is a need within the construction industry to electronically transmit standard documents between designers, owners, contractors, and material suppliers. Ideally, the transmission...
Learning and Innovating in a Construction Technology Laboratory
It has been generally recognized that the construction industry world wide, and especially in the U.S., needs innovative changes in order to produce more complex products at higher quality...
Construction Technology/Method Identification and Selection System
The proliferation of construction technology and the characteristics of technology information, such as complexity, interdependency, etc., pose the need for a well-organized technology...
Radio Frequency Data Communication Applications in the Construction Industry
Construction operations produce substantial amounts of data resulting in seemingly growing amounts of paperwork for construction personnel. Not much can be done to diminish the amount...
Kinematics and Trajectory Planning for Robotic Excavation
One of the high volume and repetitive construction operations at the construction site is the excavation of soil. Automation of the excavation work requires a robotic system that is able...
Going Where No Man Can Go
After the 1979 accident at Three Mile Island Unit 2 in Harrisburg, Pa., some areas of the reactor plant were too contaminated for workers to survey, much less clean. The article describes...
Airborne Remote Sensing of Breaking Waves with Implications for Gas Exchange
It is shown that airborne remote sensing can potentially relate gas mixing effects within a temporally evolving breaking wave to relectivity changes, and can identify the intensity of...

Lifeline Earthquake Engineering at the Turn of the Century
The author considers it a singular honor to be the first recipient of the C. Martin Duke Award under the auspices of the Technical Council on Lifeline Earthquake Engineering (TCLEE) of...
Seismic Design Practices for Power Systems: Evolution, Evaluation, and Needs
The evolution of seismic design practices in electric power systems is reviewed. In California this evolution had led to many installation practices that are directed at improving the...
First Experience Concerning the Seismic Behaviour of an Electric Power System in Eastern North America
The November 25, 1988, Saguenay earthquake of magnitude MbLg=6.5 occurred in the province of Quebec, Canada....
Aseismic Calculations for Transmission Towers
In this paper, mechanical models for long-span transmission line systems under elastic and gravitational restoring forces are established in three different directions; this continues...
Earthquake Evaluation of a Substation Network
The impact of the occurrence of a large, damaging earthquake on a regional electric power system is a function of the geographical distribution of strong shaking, the vulnerability of...
Two Decades of Communications Systems Seismic Protection Improvements
Telecommunications systems in North America have gone through significant technology changes in the past twenty years. The electro-mechanical switching equipment has been replaced by electronic...
Access Floor Response Spectra for Equipment Line-Ups in Telecommunications Central Offices
Modern telecommunications central offices very often utilize access floors to support equipment line-ups. An analytical study was carried out to study the seismic response of equipment...
Telecommunications Facilities Earthquake Readiness Since San Fernando
The vertical rack architecture of telecommunication offices showed some weaknesses during the San Fernando earthquake in 1970. Efforts have been made since then to improve performance...
Lifeline Seismic Risk Analysis Impacts of a Catastrophic Earthquake on U.S. National Lifeline Systems
Electric power, water, gas, and oil pipelines, highways, railroads and several other lifelines of critical importance at the U.S. national level have been inventoried and analyzed, to...
