The Fragmentation Of The Ulster Unionist Party, Declan Lawson George Hall

Masters Theses

In 1973, the Ulster Unionist Party fragmented after fifty years as the dominant party within Northern Ireland. However, this fragmentation did not simply occur in reaction to the events of the 1960's and early 1970's. It was a long ongoing process that can be traced back to the 1940's and 1950's.

This study is concerned with the splintering of the Ulster Unionist Party and the reasons that lay behind the division. The first contention in this thesis is that the Ulster Unionist Party was never the single united political party that it was often supposed to have been. It was …

Seasonal Lekking Behavior Of The Greater Prairie-Chicken In Illinois, Scott A. Simpson

Masters Theses

Spring behavior of prairie-chickens (Tympanuchus cupido) has been studied extensively, however there is little information on fall-winter lekking activity. Greater prairie-chickens were observed weekly on a lek from 25 September 1982 to 23 June 1983 during morning and evening hours in Jasper County, Illinois. The peak number of prairie-chicken males on the lek occurred in February although hen attendance did not occur until 10 March 1983. All spring lekking activities were higher compared to that of the fall-winter period. Fall-winter lek activity was aggression which centered on probably brief, less intense male aggression which probably establishes or maintains …

Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel

Masters Theses

Twelve Genera (spanning three Families) of Malaysian Turtles were studied to determine whether bone lengths could be correlated to mode of locomotion. Ulna, humerus, tibia, femur, coracoid (among others) were measured and results were presented graphically. Five of the genera were observed singly in a large aquarium. Data were recorded on the amount of time each spent in different locomotor modes. Both limb length data and aquarium observations suggest that turtles can be grouped into three main locomotor habits (i.e. terrestrial walking, bottomwalking, and swimming). The terrestrial group includes the genera, Geochelone, Kinixys, and Gopherus. Bottomwalkers include …

An Experimental Study Of The Effects Of Modularity On Resource Consumption In Software Development, Alan D. Christiansen

Masters Theses

"Many authors have encouraged the use of modular programming techniques in software development. In fact, there is almost total agreement within industrial and academic circles that modularity is a desirable feature of any software package. Unfortunately, the desirability of modular design is almost always voiced without support from experimental evidence.

This thesis consists of an experiment comparing the resource consumption of programmers based on the modularity practices employed during the design and programming phases of software development. The experiment tests the effectiveness of modularity in reducing psychological complexity of software.

The results of the research show that in some cases …

Crucial to the success of these control systems is the optimal trajectory modelling of the path traced by the end- effector. To create this optimal path the utilization of B-Spline curve functions will be investigated, and compared to Cubic Spline curve functions"--Abstract, page ii.

The Role Of Boron In So32 And So43 Steels, Sunil S. Moghe

Masters Theses

"In this project study was conducted with the goal of understanding the role of boron involved in structure-toughness property relationship for SO32 and SO43 steels. For a standard heat-treatment of austenitizing (1 hr.) at 1700°F, water quenching and 1 hr. tempering at 1150°F SO32 steel (with 37 ppm B) lacked in toughness, while SO43 steel (with 2 ppm B) showed good toughness. In both steels all the boron was present in the form of "soluble boron" i.e., Fe₂₃ (B,C)₆ borocarbide. Experiments were carried out to study the effect of various heat treatment parameters on the precipitation behavior of …

Thermally Stimulated Current Studies Of Barium Titanate Capacitors, Patrick Donald Martin

Masters Theses

"Thermally stimulated polarization current (TSPC) and thermally stimulated depolarization current (TSDC) measurements were used to study sample current behavior based on the thermally activated release of trapped charges and polarization mechanisms. Samples studied included laboratory-prepared barium titanate samples (the barium to titanium ratio ranging from 0.96 to 1.04) and commercial ceramic capacitors. Both TSPC and TSDC showed the current spectra of the barium titanate samples were a function of crystal structure and the Ba/Ti ratio. The TSPC/TSDC results of the ceramic capacitors showed differences between capacitor formulations. TSPC/TSDC results also showed differences between good capacitors (physically and electrically) and capacitors …

A Study On Fragmentation And Ground Vibration With Air Space In The Blasthole, Everett Ellsworth Bleakney Iii

Masters Theses

"The degree of fragmentation and the level of ground vibration from a bench blast employing standard full-column completely-coupled explosive charges are commonly controlled by varying one or more of the many dimensional variables of blast design. Blasting techniques such as decoupling and air-gapping, utilizing air space in the blasthole, have also been reported as having the potential to control rock fragmentation and ground vibration.

This investigation, using reduced-scale in situ bench blasts, examined the degree of fragmentation and the level of ground vibrations produced from the standard full-column completely-coupled, air-gapped, and decoupled methods of blasting to:

1. Compare the effectiveness …

An Investigation Of Methods Of Surface Estimation With Application To The Interpolation Of Antenna Patterns, Paul Matthew Niall Feehan

Masters Theses

"The problem of estimating a surface from a set of discrete measurements lying along straight lines is considered. This situation arises when one attempts to determine the S-Band antenna gain pattern for the Space Shuttle, from measurements taken at several ground stations. The results of previous investigators concerned with the performance of surface approximation techniques for the present application, are extended in this study by examining the case where the data samples are corrupted by measurement noise. Results have been obtained using least-squares approximation with bicubic B-spline basis functions, and for an interpolation algorithm in conjunction with a spatial smoothing …

Lithology And Sedimentology Of The Graydon Springs Channel, Pennsylvanian Of Southwestern Missouri, Gregory Lee Easson

Masters Theses

"The Graydon Springs Member of Southwest Missouri, here assigned to the Warner Formation of Pennsylvanian age was sampled and examined in order to document the lithology, sedimentology, source area, stratigraphic position, and overall geologic history of these channel-like bodies. The member is composed of an upper sandstone unit and a lower conglomerate unit.

Laboratory investigations of thin sections indicate that the sandstone unit is composed of well sorted, well rounded quartz and minor amounts of accessory minerals cemented with iron oxide, commonly hematite. Field observations indicate that the conglomerate unit is composed of very poorly sorted, very well rounded chert …

A Simple Method For Organizing Nearly Optimal Binary Search Trees, Joy L. Henderson

Masters Theses

"Improving the efficiency of retrieving information concerns users of computer systems involved in many applications- One way of addressing this concern is to organize a sorted sequence into a binary search tree. Knuth's Algorithm K is a bottom-up organization algorithm that always constructs a binary tree which minimizes average search time. However, the cost of executing Algorithm K is prohibitive for a large tree. The aim of this work is to find a less costly method of organizing sorted sequences into nearly-optimal binary search trees.

We present a top-down organization method which yields better average search times than top-down methods …

Hydrogen, carbon, nitrogen, sulfur and oxygen percentages were determined by elemental analyses. Trace element composition was determined by emmission spectroscopy and the composition of the bitumen was calculated with respect to aromatic hydrocarbons, saturated hydrocarbons and NSO (nitrogen-sulfur-oxygen) components. The bitumen and kerogen from associated shale samples were evaluated by Rock-Eval pyrolysis and pyrolysis-gas chromatography.

The bitumen was calculated to be approximately 40 to 50 percent aromatic and …

Structural Behavior Of Cold-Formed Steel Beam Webs Subjected To Partial Edge Loading, Shin-Hua Lin

Masters Theses

"An extensive experimental investigation has been conducted to study the load-carrying capacity of cold-formed steel web elements subjected to partial edge loading which may cause web crippling or web buckling. In this experimental work emphasis was concentrated on the cold-formed steel structural members having single unreinforced webs with stiffened flanges.

In 1980, American Iron and Steel Institute (AISI) revised its "Specification for the Design of Cold-Formed Steel Structural Members.” For the design of beam webs, Section 3.5.1 of the AISI Specification provides the design criteria for web crippling. This thesis discusses the experimental work including some specimens with small length-to-depth …

Oil Producing Upper Cherokee And Lower Marmaton (Pennsylvanian) Channel Sandstones Of Jackson And Cass Counties, Missouri, Stephen Thomas Carroll

Masters Theses

"Approximately 240 gamma ray-neutron logs were interpreted and correlated in an attempt to isolate separate channels collectively referred to as "Squirrel" sands in the upper Cherokee and lower Marmaton (Pennsylvanian) rocks of Jackson and Cass counties, Missouri. Isopach maps were prepared for two of the identifiable fluvial sandstones and a structure map was drawn on the laterally extensive Anna Shale.

The term "Squirrel" has been applied to as many as five different sandstone packages, and thus, has been the source of a great deal of confusion. In an attempt to sort out the confusion this thesis recognizes and defines three …

A Focus Of Attention Algorithm For Expert Systems, Kevin W. Whiting

Masters Theses

"This research is primarily concerned with increasing the performance of expert systems. A refined focus of attention strategy and its affect on performance are discussed. Early expert systems used a brute force approach to process the knowledge base. Each production rule in the knowledge base was evaluated each cycle. More recently, processing efficiency has been increased by focusing the attention of the inference engine on a subset of the rules by "filtering" for further testing, only rules that could possibly fire given the current content of the context base. Focus of attention as developed in this research increases performance over …
