Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
A Shopper's Guide to Urban Stormwater Software, Revisited
Results of a survey of urban stormwater software were first discussed by the author in August, 1985. A trend toward widespread adoption of SCS procedures as a new standard in urban hydrology...
Earthmoving in the Lunar Environment
This paper analyzes the lunar 'earthmoving' process with inputs, outputs, and external conditions acting upon it. Lunar environmental conditions such as temperature,...
Candor Chasma Camp
This paper proposes a camp at Mars, in the Coprates region of the Valles Marineris rift, just below the equator on Candor Mensa 6�-12'S, 73�-30'W. Beginning at...
Dynamic Analysis of the Joint Dominated Beam
A method is presented herein to determine the vibration modes of the Joint Dominated Beam. An example of a cantilever beam is selected for this purpose. The truss type beam is analysed...
Differential Gravitional Forces on Large Space Structures
Effects of the differential gravitational forces have been investigated simultaneously on the orbital motion, attitude motion, and axial deformation of a very large axially flexible space...
Animation/Simulation for Construction Planning
The importance of a highly efficient schedule for space construction cannot be overestimated. A detailed scheduling process working closely with design data could reduce costs, minimize...
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...
The Planar Truss - An Active Control Test Bed
The authors have developed a laboratory planar truss and structural dynamic models which correlate well. The inherent fraction critical damping (? = .004 for the first mode) is very low...
Space Construction Animator: Functional Requirements
This paper explores the idea of developing integrated design/construction tools. In order to develop suitable computer graphics integrated tools for space construction operations, the...
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
CADD, The Integrated Data Base (IDB), and Engineering, Construction and Operations (EC&O) in Space
This paper is written from the viewpoint of Engineering Technical Managers interested in applying automation tools to the building process. Engineering, Construction and Operations in...
A Visual Approach for Space Systems Designers
This paper discusses computerized tools that may be used by designers as they approach problem solving related to engineering, construction and operations in space. Tools for space system...
Earthquake Engineering and Soil Dynamics II?Recent Advances in Ground-Motion Evaluation
Ground-motion determination for analysis and design of engineering structures is a shared, interdisciplinary task involving geologists, seismologists, geophysicists, geotechnical engineers,...
Affordable CADD
In the past few years many civil engineers have become aware of the advantages of CADD systems. However, CADD systems were originally prohibitively expensive for all but the largest offices....
New Roads for the Micro
Using microcomputers loaded with database software and Fortran programming, engineers are gaining control of pavement maintenance. A number of factors, from urban sprawl to constricting...
Support the Complex
A computerized decision support system (DSS) can help manage the uncertainties of a complex construction project. A construction DSS consists of two interlocking parts. First, it is a...
Databasics
Databases can replace both manual methods and specific software packages written for a variety of tasks in the engineering office. The flexibility of a database makes it more useful than...
Keeping Tabs on CADD
In 1983 Howard Needles Tammen and Bergendoff (HNTB) began to implement a CADD system. Fostering the independence of individual offices while maintaining the company wide standards and...
