Developing Non-skid Road Surfaces
In the second direction, accompanying this outdoor ex posure, will be the standard laboratory tests on these same materials after they have been subjected to freezing and thaw ing, wetting and drying. Such laboratory work will, when compared to the outdoor experiment, tell us whether or not it is necessary to go through the actual construction of a test road in order to find out what may othe...
متن کاملSkid-Scale Cryogenic Carbon Capture
The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas, separates the resulting solid from the remaining light gases, pressurizes the solid CO2, melts the CO2 and warms the light gas, and completes the CO2 pressurization with liquid CO2. This skid-scale CCC system has demonstrated successful carbon capture of 90–99% from simu...
متن کاملSkid Resistance Guidelines for Surface Improvements
This report pertains to the selection of a minimum skid resistance for use as another guideline for surface improvements by the Texas Highway Department. This problem was approached from an accident standpoint as well as from a design standpoint, since experience on several sections of roadway indicated a sharp reduction of accidents after surface improvements. Skid resistance and accident data...
متن کاملHomeless alcoholic women on skid row.
Studies of homeless alcoholic women remain rare. Women on Skid Row in New York City were sought out at the Women's Shelter for a study of homeless women alcoholics. The findings in this study of 31 homeless alcoholic women tend to confirm an earlier study by Garrett and Bahr in most respects. A major difference relates to the population's lack of homogeneity. A life-long pattern of marginality ...
متن کاملFuzzy Logic Based Autonomous Skid Steering
A two-layer fuzzy logic controller has been designed for 2-D autonomous navigation of a skid steering vehicle in an obstacle filled environment. The first layer of the fuzzy controller provides a model for multiple sonar sensor input fusion and it is composed of four individual controllers, each calculating a collision possibility in front, back, left and right directions of movement. The secon...
