In this paper, we derive a simple method for estimating the International Roughness Index (IRI) of a pavement profile using data collected by a computerized profilograph. The algorithm presented herein achieves this by estimating the standard deviation of the point-to-point slope of the pavement from the profilograph's recorded data and then mapping this to an expected IRI via a theoretically justified...
This paper describes a simple computer design and an associated full screen PC-based simulator used to teach basic hardware and software concepts in Introduction to Computer Engineering, a sophomore level course at Kansas State University. The culmination of the course is the presentation of a complete CPU which could be built from the SSI and MSI circuits studied in the course. The CPU design is...
