An Experimental Investigation Of Receiver System Sensitivity, James Henry Johnson

Masters Theses

"A method of determining the minimum detectable power density incident at the receiving antenna of a UHF receiver is proposed. The minimum detectable power density is the power density required to produce a signal-to-noise ratio of unity in the output of the receiver. The proposed method includes the receiving antenna impedance, the necessary connecting transmission lines, and the receiver impedance.

It is shown that an error in the antenna directivity will produce a significant error in the overall sensitivity of a receiving system. Since the directivity is the most difficult system variable to determine experimentally, it is probably the limiting …

The Effect Of Recorded Lateral Lisping On Listener Comprehension, Leslie Gene Adkins

Masters Theses

The Problem

This experiment was designed to test the effect of misarticulation on listener comprehension. Of the many authorities who suggest that poor speaking reduces comprehension, Knower, Phillips, and Koeppel state: "Poor speaking seems to be the least effective method of presenting informative materials. There is a direct relationship between the quality of speaking performance and the amount of material recall." One of the important factors which contributes to effective speaking is correct articulation. According to Van Riper and Irwin: "If you misarticulate your speech sounds, it interferes with communication, and your speech is judged as abnormal." Articulation defects are …

The Correspondence Of Error Between The Voiced And Unvoiced Cognates “S” And “Z” In Children With Articulatory Disorders, Gerald F. Johnson

Masters Theses

Introduction

The problem as set forth in this thesis is to determine the correspondence of error between the voiced and unvoiced cognates "s" and "z" in children with articulatory disorders. It has been assumed that the correspondence of error type would be high due to the similarity of the sounds. Anderson, for example, says that "much of what is true with respect to "s" applies with equal force to its voiced analogue "z"." The problem of this research is to determine whether there is any correspondence between the respective errors on the sibilants "s" and "z" and if they correspond …

An Investigation Of The Relationship Of Tongue Clicking To Mandibular Descent, Amy Louise Bricker

Masters Theses

Introduction

The movement of the tongue has been of concern for many years to the speech therapist. At one time tongue exercises were of prime importance in this field but due to the gross misuse of the exercises, they have now become of little importance. Only recently has the motor functioning of the tongue attracted renewed interest. Although the activity of the tongue has often been studied, none of the studies to our knowledge have included the control of jaw movement. Since the genio-glossus muscle serves as the bulk of the tongue and has its origin on the mandible, the …

An Analysis Of The Articulation Errors In Spontaneous Speech Of One Hundred Children With Lisps, Paula C. Downs

Masters Theses

The Problem

This study is an attempt to determine the nature and relative frequency of the articulation errors shown by one hundred school children with lisps.

The Importance of Investigating the Phenomenon of Defective Articulation

The incidence of speech defects in the child population has been found to range from five percent (5%) to ten percent (10%) of the total child population. A child's speech is considered defective when the listener gives as much or more attention to the manner in which the child speaks as he does to the idea being communicated.

A Study Of The Effects Of Delayed Side-Tone Upon Voiced And Whispered Reading Time, Bruce Presten Ryan

Masters Theses

Definition of Delayed Side-Tone

The term delayed side-tone feedback refers to the delaying of one's hearing of himself by a fraction of a second, so that instead of hearing himself as he normally does, he hears himself or his own speech a fraction of a second later.

...in order to produce delayed speech feedback it is necessary to return the speaker's speech to his own ears approximately one-means of a magnetic tape recording and reproducing machine which has used to experience the effect prominently since they deliver delayed speech and exclude the normal air-borne undelayed speech sound which provides the …

The Geology Of The Uranium-Vanadium Deposit Of The Diamond No. 2 Mine, Near Gallup, New Mexico, Raymundo J. Chico

Masters Theses

"This thesis deals with the geology of the Diamond No. 2 Mine east of Gallup, New Mexico. The sedimentary rocks ranging from Triassic to Cretaceous are described in relation to the local stratigraphic setting.

The Dakota formation is the host rock of the ore deposit, and was therefore studied in detail with regard to its petrographic nature and the sedimentary structures such as slumping. Special emphasis is placed on the study of the relationships between the uranium and vanadium deposit and the host rock. Geometrical and geochemical criteria are offered in order to explain the local genesis of the ore …

Regulation Of River Bank Development Through Flood Plain Zoning, William James O'Neill

Masters Theses

"The triangular pattern of protection, evacuation and flood plain zoning, as the only truly effective and comprehensive approach to proper flood control, is substantiated in practically all technical publications on this subject by economic and engineering leaders. Yet in actual practice, at the present time, flood plain zoning is not being actively applied by any federal flood control agency and by only one of the forty-nine states faced with this common problem. This lack of direct application was probably best described recently by Walter B. Langbein, Water Resources Division Engineer, U. S. Geological Survey when he said, "Flood Plain Zoning, …

Application Of Statistical Methods To Evaluation Of Mineral Deposits, Francis R. Saupé

Masters Theses

"Only in recent years have statistical methods been applied to evaluation of ore reserves. An attempt is made in this study to prepare an outline to be followed throughout the exploration in order that statistical methods can be applied to valuation problems. Particular emphasis is given to the preliminary requirements to a statistical approach. Representative parameters, sampling pattern, and sample size are discussed in separate chapters"--Abstract, page iii.

The Effects Of Manifest Anxiety On Stuttering Adaptation, Joseph Agnello

Masters Theses

I. Introduction

When stuttering behavior is viewed as a problem in learning, the phenomenon of adaptation frequently receives attention. A standard adaptation experiment consists of having the person who stutters re-read the same passage, or a passage of equal difficulty, a specified number of times. Under these conditions a relative reduction¹ in stuttering frequency usually occurs. Experimentalists and clinicians alike have long been puzzled as to why this decrement takes place, since stuttering is generally considered by many writers^2,3 as a self-reinforcing disorder; that is, stuttering produces more stuttering.

The present experiment was designed to investigate the effects, …

The Effect Of Recorded Stuttering On Listener Compression, Harold Walter William Homann

Masters Theses

Chapter I.

The Problem

Justification of this research. This experiment was designed to test the prevalent opinion that poor speaking reduces comprehension. Typical of such opinions is the conclusion of Knower, Phillips, and Koeppel¹, who state:

"The comparative effectiveness of speaking and oral reading as methods of presenting material depends upon the quality of performance. Poor speaking seems to be the least effective method of presenting informative materials. There is a direct relationship between the quality of speaking performance and the amount of material recalled. Poor speakers produced least recall."

Of the many factors which contribute to effective …

The Analysis And Evaluation Of Supervisory And Managerial Personnel, Robert A. Huston

Masters Theses

Introduction

The rapid growth of American industry during the first half of the Twentieth Century has brought managements face to face with the necessity to delegate responsibility and commensurate authority to the various echelons of the supervisory and managerial personnel. The owner-manager era is a thing of the past. Gone with it is the intimate relationship that once existed between the owner of the business and those who worked for him. In its place has arisen the corporation, a statutory entity that cloaked ownership with impersonality.

Coincidental with the change of character of ownership and, indeed, one of the major …

Paragenesis Of The Minerals In The Einstein Vein Madison County, Missouri, Robert P. Stevens

Masters Theses

"Selection of the Problem: The mineralogical problem of determining the paragenetic sequence of minerals in the Einstein vein, Madison County, Missouri, was suggested by Dr. O. R. Grawe, who previously had supervised a thesis by Joel Pomerene dealing with the geology of the area. Although considerable attention has been given to the mineralization along the vein, a specific study of the paragenetic relations has not been made. Paragenesis has, however, been discussed by others in papers dealing with the geology of the area. Such a study is extremely important in the establishment of a hypothesis of origin, and hence, an …

A Comparative Study Of The Jaw Movements Of Children With Normal And Abnormal Articulation, Jean Fraser Ward

Masters Theses

Review of the Literature

Introduction

It is surprising that there exist relatively few studies of the movement of the mandible or lower jaw with regard to misarticulation while the activity of the tongue, on the contrary, has received much attention. The purpose of this experiment is to investigate the extent of mandibular movement in the production of nonsense syllables and sentences as spoken by children with dyslalic and normal speech.

An Investigation Of The Dissolution Of Hafnium-Free Zirconium In Hydrofluoric Acid And The Effect Of Fluoride Additions, Alfred S. Neiman

Masters Theses

"Hafnium-free zirconium has assumed great importance in commercial use in recent years. When economical methods were developed in 1950 to remove hafnium from Zr, a metal was produced which not only exhibited good corrosion resistance and desirable physical properties, but also had a very low absorption cross section for thermal neutrons. Such a metal could obviously be utilized to advantage as a structural material for nuclear reactors. This application is the most important one for Zr at present.

Good corrosion resistance to most mineral acids is one of the outstanding non-nuclear properties of Zr. Hf-free Zr has good corrosion resistance …

An Investigation Of Certain Factors Influencing The Testing Of Auditory Phonetic Discrimination, Warren Scott Curtis

Masters Theses

The Background of the Problem

Review of the Literature

The importance of auditory phonetic discrimination in speech therapy. One of the basic criteria for good articulation is that the individual sounds or phonetic units which make up a word must be produced correctly and arranged properly in sequence. According to Van Riper (32:127), when a speaker adds, omits or distorts a particular phoneme to the extent that it alters word meaning, calls attention to itself, and/or produces unpleasant emotional reactions in the speaker or audience, he is adjusted to have an articulation defect.
