This course explores testing and measurement methods in Civil Engineering including: land surveying, the experimental analysis to explore the engineering properties of metals and concrete and nondestructive evaluation techniques. Students will gain a basic knowledge of drawing in the digital environment using AutoCAD Civil 3-D, the engineering industry design standard.
The course is intended to acquaint students with environmental acoustics and the application of acoustic waves to remote environmental monitoring. Students will learn how to measure and suppress environmental noise and how underwater acoustic systems are used for remote measurements of various ocean and river parameters, including: bottom profile, surface waves, current, bubble and fish density, etc. The course also surveys recent developments in acoustic tomography, including global warming control. Students will be asked to write a research paper on the application of acquired methods to remote acoustic measurements conducted at Stevens.
This course will introduce principles and applications of Nondestructive Evaluation (NDE) techniques, which are important in design, manufacturing, and maintenance. Most commonly used methods such as ultrasonic, magnetic, radiography, penetrates, and eddy currents will be discussed. Physical concepts behind each of these methods as well as practical examples of their applications will be emphasized.
Fundamental concepts of particle statics, equivalent force systems, equilibrium of rigid bodies, analysis of trusses and frames, forces in beam and machine parts, stress and strain, tension, shear and bending moment, flexure, combined loading, energy methods, statically indeterminate structures.
This course exposes the student to the physical principles underlying remote sensing of ocean, atmosphere, and land by electromagnetic and acoustic passive and active sensors: radars, lidars, infrared and microwaves thermal sensors, sonars, sodars, infrasound/seismic detectors. Topics include fundamental concepts of electromagnetic and acoustic wave interactions with oceanic, atmospheric, and land environment, as well as with natural and man-made objects. Examples from selected sensors will be used to illustrate the information extraction process, and applications of the data for environmental monitoring, oceanography, meteorology, and security/military objectives.
