Condensation method for humidity measurement in the UMR cloud simulation chamber

The University of Missouri-Rolla has developed a cloud simulation facility for the study of various atmospheric cloud processes. The initial relative humidity of the air sample put into the cloud chamber is a key parameter in virtually any experiment and needs to be known accurately. This report describes how the cloud simulation chamber itself has been used as a condensation type hygrometer to calibrate the system’s humidifier. Two distinct and physically different methods for inferring mixing ratio are used, one exploiting the sensitivity of aerosol activation to humidity, and the other exploiting the sensitivity of the rate of growth of cloud droplets to humidity. The two methods give agreement with each other to within a precision of one part per thousand in mixing ratio.

TEM study of boron additions to cobalt aluminide

In recent years an increasing emphasis has been placed on the study of high temperature intermetallic compounds for possible aerospace applications. One group of interest is the B2 aiuminides. This group of intermetaliics has a very high melting temperature, good high temperature, and excellent specific strength. These qualities make it a candidate for applications such as turbine engines. The B2 aiuminides exist over a wide range of compositions and also have a large solubility for third element substitutional additions, which may allow alloying additions to overcome their major drawback, their brittle nature.One B2 aluminide currently being studied is cobalt aluminide. Optical microscopy of CoAl alloys produced at the University of Missouri-Rolla showed a dramatic decrease in the grain size which affects the yield strength and flow stress of long range ordered alloys, and a change in the grain shape with the addition of 0.5 % boron.

A Potential Method for Predicting Coal-Mine Floor Heave: ABSTRACT

Floor or deformation of the mine floor into the mine opening is a problem which has plagued coal mines in this country and others. This paper describes the problem as it was manifested in two coal mines located in eastern Illinois, and reports the results of a U.S. Bureau of Mines-sponsored study conducted by the University of Missouri-Rolla. The ultimate objective of the study was to develop a procedure that could be used to define a potential floor problem during the exploration phase of mine design--before initiation of production mining. Floor within the mines did not occur with uniform intensity throughout each mine or even within mine panels. Floor deformation was often deep-seated and involved two subfloor lithologies. A wide variation in measured strength for each of the subcoal lithologies was recorded during laboratory testing; underclay triaxial compressive strength best correlated with underclay natural water content. The severely heaved areas were not located in the deepest or shallowest portions of the mines. Severe floor occurred in areas of thicker (greater than 6 ft, 2 m) underclay. Severe floor occurred at those sites where the natural water contents of the underclay and claystone were highest. The presence of swelling montmorillonite clay did not seem to be a major cause of floor Triaxial compressive strengths measured from underclay samples from severely heaved sites were not the lowest values measured. A bearing capacity model developed by Vesic was modified so that a heave factor could be calculated using only that information obtainable from exploration core borings; use of the heave factor would have predicted floor at the study sites where severe occurred.

Increasing the Oral Communication Competencies of the Technological Student: The Professional Speaking Method

This paper discusses a method to improve the oral communication competencies of technological students that has been utilized successfully at the University of Missouri-Rolla, the main scientific/engineering school of the University of Missouri system. Methods of individual instruction are explored, including personal assessment of strengths and weaknesses, individualization of course goals, time management, and the reduction of communication anxiety. Methods of group instruction are also detailed, including different types of oral presentations the technologist might be expected to make, building a professional attitude, the professional portfolio, and out-of-class speaking experience. Two premises form the basis for these methods. First, that a strong individual approach will significantly increase competencies in oral communication while reducing anxiety. And second, that emphasizing a professional attitude will encourage the student to work to his capacity in improving his competencies, and will prepare him to be a more effective professional.

Toward More Meaningful Laboratory Experiences in Digital Signal Processing and Digital Control

Digital signal processing and digital control are of utmost importance for electrical engineering students, for they are present in many aspects of today's technical world. Complex topics like these should not be introduced into a curriculum as a crash program, but taken as steps in an evolutionary process. A successful example of this evolutionary process is well underway at the University of Missouri-Rolla.
