Sediment Discharge Measurement with a Point Sampler
A procedure for measuring total sediment discharge using point-source suspended-sediment data was developed. The proposed procedure, Total Sediment Discharge (TSD), was tested with field...
Identification of Automation Opportunities
Construction, although the world's largest industry, is also its most archaic. Most construction practices are very labor-intensive, with resulting impacts on safety, productivity,...
Terrestrial Trends for Building Technology in North America
This paper discusses new building technologies that will develop in the early 1990's to become significant technologies by the mid 1990's. The perspective is...
The Role and Functions of an Analog Moon Base
Over the past two decades numerous studies, workshops and symposia have identified the rationale for and characteristics of a permanently inhabited base on the Moon. This paper discusses...
Intelligent Construction Machines for Initial Planetary Shelter Fabrication
There have been any number of artists panoramas of initial base and habitat construction on other planetary bodies, notably recently the moon. Most of these conceptual drawings assume...
Telerobotics Design Issues for Space Construction
The efforts of a recent study aimed at identifying key issues and trade-offs associated with using a Flight Telerobotic Servicer (FTS) to aid in Space Station construction phase tasks...
Robotic Space Construction
This paper touches briefly on some of the highlights of Langley's work in automated space construction. It shows that space trusses similar to those likely to be used on the...
Robotics Research for Construction in Space
Research in construction robotics, terrestrial or otherwise, has focused on issues which are broadly pertinent to space applications. Construction robotics, as addressed by this writer,...
Robotic Influence in the Conceptual Design of Mechanical Systems in Space and Vice Versa: A Survey
A survey is presented of the methods of constructing structural elements in space by the application of robotic devices. Two fundamentally different approaches to the solution of robotic...
Simulator for Telerobotic Assembly, Maintenance and Repair of Large Space Structures
A first approximation level computer simulator for telerobotic assembly of large space structures is described. Approach, methodology and initial results are presented. An example based...
Lunar Automatic Photoelectric Telescopes (LAPTs)
I propose a lunar network of modest (approximately 1 m), robust telescopes designed for and dedicated to precise, time-serial monitoring of variable sources. Unhampered by atmospheric...
Advanced Technology for a Lunar Astronomical Observatory
Significant new technologies are required for three proposed telescopes to be operated on the Moon. These technologies are in the areas of contamination/interference control, test and...
Astrotectonics: An Overview
Astrotectonics is the science of construction in space of both orbital and planetary structures and facilities, as well as orbitally assembled interplanetary spacecraft. The success of...
Long Distance Dam Data
Remote data collection systems are increasingly being used for dams. Instrumentation of structures for obtaining data on performance is not new. However, automation and computerization...
Computing on the Run
Portable computers enable engineers to manage projects right at the job site. In addition to this mobility and flexibility, they make it possible for a small firm to automate inexpensively....
Advanced Vehicle Command and Control System
The Advanced Vehicle Command and Control System (AVCCS) is being developed to solve capacity problems on major urban highways using automation and current technology. The objective of...
Implementation of Highway Research in California
In March 1988 ASCE conducted a national workshop on highway research. This paper will discuss the ten commandments from the perspective of the California Department of Transportation....
Computers Board Equipment
Construction equipment is slowly being automated, either with remotely operated radio controls or by on-board computers that control repetitive tasks. Contractors in the United States...
Automating Bridge Design
To avoid some of the pitfalls of manual design calculations, Parsons Brinckerhoff Quade & Douglas engineers designing a series of bridges for a $280 million section of the New...
Overview of Canal Control Concepts
An overview of terminology and philosophies of canal control, plus brief descriptions of canal automation technologies, is given. The justification given for examining control schemes...
