Force and Geometry Constraints in Robot Excavation
One interest in this research effort was to develop and test an automatic control approach to adjust machine motions to the force conditions encountered during excavation - essentially...
New Technologies for Unmanned Space Exploration
There could be no better time than now for the development and implementation of new technologies such as V.L.S.I. and optoeraseable storage. Creative inventions from new mathematical...
Stopping Waste at the Source
Contrary to popular belief, waste reduction at the source, rather than end-of-the-pipe waste treatment may the nation's best approach to the hazardous waste problem. Surprisingly,...
Local Area Networks, a Hardware and Software Tutorial
The ability to develop, access and manage information has become a strategic component of a competitive and productive office. The capability to connect groups of microcomputers is now...
Application of Interactive Videodisc for Work Zone Traffic Control Training
This paper describes the development of the Interactive Videodisc Training (IVT) system and a training course on work zone traffic control. The IVT system uses a microcomputer-controlled...
Choosing Display Hardware for Transportation Planning Packages
This paper reviews the popular transportation planning software packages on the market and their graphics capabilities. Hardware options that allow the user tp achieve high resolution...
Computer-Assisted Creativity for Traffic Problems
The main objectives of this paper are to describe a system for computer-assisted creativity, or innovation support, known as The Idea Machine (TIM), and to highlight two case study applications...
Field Calibration of Neutron Gauges: SCS Method
Field calibration of neutron gauges is easy and requires very little time under normal circumstances. Special soil sampling equipment is required that can be fabricated by most machine...
Experimental Research and Parameters Optimization of a Prototype OWC Wave Power Device
The paper presents the experimental research and parameters optimization of a prototype oscillating water column (OWC) wave power device being built in China by Guangzhou Institute of...
Experimental Investigation of Condensation of Steam in the Presence of Noncondensable Gases for Open-Cycle Surface Condensers
Two experimental investigations are being carried out for determination of the effects of noncondensable gases on the rate of condensation in the open-cycle surface condenser. A single-channel...
Comparative Evaluation of 4-Inch and 6-Inch Diameter Specimens for Testing Large Stone Asphalt Mixes
Modified Marshall equipment and Gyratory Testing Machine (GTM) are now available for compacting and testing 6-inch diameter specimens to accommodate aggregate up to 2-inch maximum size....
Development of a Plane-Strain Device for Soft Rock
Work is now in progress to build a plane-strain apparatus for 'soft' (unconfined compressive strenghts below 35 MPa) rock and concrete, based upon a passive,...
Commuting Computing
Portable computers come in many different shapes and sizes and boast many of the same features as desktop machines. Unlike desktop PCs, however, the key to getting the most use out of...
Seattle Swing
The swing bridge has long been out of favor in the U.S. because of the navigational hazard presented by mid-channel pivot piers. A consortium of engineers is updating the design to a state-of-the-art...
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Optimum Design of Tapered Tubular Members
An algorithm for designing a tubular structural member with constant taper is presented. The design criterion is that the maximum absolute stress produced by a set of loading conditions...
Floor Response Spectra Including Structure-Equipment Interaction Effects
An efficient method for generating floor response spectra with the structure-equipment interaction effects is proposed. Floor response spectra are computed from a prescribed ground response...
