An Evaluation of a Cloud Seeding Program in Utah

Establishing Rock Mass Properties for a Power Plant in Weathered Volcanic Rocks

Meteorological Impacts on Urban Sulfate Levels
Sulfate levels in Boston, Mass. demonstrated a high correlation with meteorological parameters indicative of long-range transport of aerosols. Two-hour average samples of total sulfate...

Fatigue Tests of 3-yr Weathered A588 Steel Weldment
The effect of 3-yr weathering on the fatigue behavior of a transverse stiffener detail fabricated from ASTM A588 weathering steel was determined experimentally. The 16 specimens fatigue...

Hurricane Wind Speeds in the United States
A Monte Carlo simulation technique is used to obtain estimates of hurricane wind speeds along the Gulf and East Coasts of the United States. The paper describes the sources of data, the...

Flight Instrumentation Requirements for All-Weather Approach and Landing

Selection of Air-Quality Models
The basic question still exists as to what type of model to use and the validity of the predictions. Some of the data that affect the credibility of model predictions are dependent upon...

Simulation of Construction Project Duration
MUD (model for uncertainty determination) will simulate the progress under uncertainty of the typical construction project on which the activity durations are not independent of each other....

Characterization of Ozone Episodes in Urban Air
Air pollution and meteorological data were collected in Chicago during August and early September for 54 and 39 consecutive days in 1976 and 1977, respectively. Regular measurements were...

Archeology and Construction in the North

Specific Features of Constructing Underground Hydraulic Structures in Permafrost Conditions

Winter Road Construction Techniques

Design Considerations for Airfields in NPRA

Heavy Falls of Hail and Rain Leading to Roof Collapse
The operation of two large and dense weather networks to record and measure rainfall and hailfalls in two urban areas have yielded interesting weather-damage information that may need...

Sampling Errors in Estimation of Extreme Winds
An investigation is presented into the question of whether series of extreme wind speed data in climates not subjected to hurricane winds are best fit by Type I or Type II extreme distributions....

Markov Process for Simulating Daily Point Rainfall
A modified Markov Chain model is used to generate synthetic traces of daily rainfall amounts at a point. Mixed discrete-continuous distributions are used to model the state transition...

Foundation Bearing in Weathered Rock

Temporary Protection of Cold Weather Construction
The literature of cold weather construction documents the importance of providing temporary protection of projects during the winter in northern regions. A survey of Alaskan contractors...

Motion of Suspended Bridge Spans under Gusty Wind
The buffeting response of suspended-span bridges can be calculated if certain wind-tunnel section model data, plus wind spectral information, are provided. The needed wind tunnel data...

Structural Characteristics of Weathered Plywood
Plywood exposed for more than 21 yr to continuous weathering and use as the roof decking of portable hog houses was found to have strength properties comparable to those expected in new...
