Logan Canyon is located east of Logan, Utah, in the Bear River Range. The lower part of Logan Canyon is considered that section of the canyon from its mouth upstream to Tony Grove Canyon, a distance of 22 miles, Figure 1 Some tributary canyons of the lower part of Logan Canyon have been included in this investigation because of their relationship to Logan Canyon. Grassy Flat Canyon, a south tributary of Logan Canyon 4.4 miles from Logan, exhibits several geomorphic features related to the geology of Logan Canyon. Because of its extensive use and close association with Logan Canyon, Tony Grove Canyon is also included. Tony Grove Canyon extends from Logan Canyon northwestward to the crest of the Bear River Range, a distance of about six miles. More than 20,000 feet of Paleozoic rocks ranging in age from Cambrian to Pennsylvanian are exposed in Logan Canyon . Cenozoic deposits are widespread in and near the canyon. The crest of the Bear River Range near Naomi Peak and Tony Grove Canyon was the center of glacial activity during the Pleistocene. During the glaciations of Tony Grove Canyon, Lake Bonneville extended into Logan Canyon and influenced the geomorphic development near the mouth of the canyon. Logan Canyon is vital to the economy of Cache Valley. The canyon is a large part of the Logan River watershed. Logan River passes through three hydroelectric plants in Logan Canyon and supplies culinary and irrigation water for the valley below. Animals and plants of a wide variety are abundant, providing fishing , hunting, and a harvest of forest products. U.S. highway 89 traverses the canyon and carries a large volume of traffic to points within the canyon, as well as to other areas. Logan Canyon is entirely within the Cache National Forest. Improved campsites and recreational facilities, which were used by almost 1.5 million visitors during 1963; according to the U. S. Forest Service, are located throughout the Canyon. Increased recreational and travel use of the canyon has resulted in a demand for more geologic work in this area .

The northern part of the Oxford Quadrangle, Idaho, includes parts of the Bannock Range to the west and the Portneuf Range to the east. These ranges are separated by Marsh Valley to the north and Cache Valley to the south. Red Rock Pass, the outlet of glacial Lake Bonneville, divides the two valleys. The mapped area is north of Preston, Idaho, and south of Downey, Idaho. The north-south dimension of the mapped area is 5.2 miles and the east-west dimension is 6.4 miles. The stratigraphic units, within the mapped area, are Precambrian, Paleozoic, and Cenozic in age. The oldest rock unit is the Pocatello Formation of late Precambrian age. Other Precambrian units, in ascending order, are the Papoose Creek Formation and the Caddy Canyon Quartzite. The Precambrian units are dominantly argillite and quartzite with some extrusive and intrusive metaigneous rocks. The Cambrian formations, in ascending order, are the Langston, Ute, Blacksmith, Bloomington, Nounan, and St. Charles Formations. The Cambrian units are dominantly limestone and dolomite, with interbedded shale. Ordovician formations consist of the basal Garden City Formation which is limestone and the Swan Peak Formation which is quartzite. The Tertiary Salt Lake Formation is dominantly tuff and conglomerate. The Quaternary is represented by colluvial deposits, Lake Bonneville Group, and alluvial deposits. Major structural features, within the mapped area, are thrust faults and normal faults. A major thrust fault places Middle Cambrian rocks on Precambrian rocks and eliminates a significant part of the stratigraphic column. Thrust faults are also present between Papoose Creek Formation and Caddy Canyon Quartzite, Bloomington and Nounan Formations, St. Charles and Garden City Formations, and Garden City and Swan Peak Formations. The evidence, within the mapped area, indicates eastward thrusting. The normal faults postdate the thrust faults and offset Salt Lake Formation. The normal faults generally trend north-northwest. These structural features are the result of two separate events. The thrust faulting and related deformation is late Jurassic to Eocene in age. The Basin and Range normal faulting began in late Eocene and continued to Holocene.

Indiana University-Purdue University Indianapolis (IUPUI) / The two-part model (2PM) is the most widely applied modeling and estimation framework in empirical health economics. By design, the two-part model allows the process governing observation at zero to systematically differ from that which determines non-zero observations. The former is commonly referred to as the extensive margin (EM) and the latter is called the intensive margin (IM). The analytic focus of my dissertation is on the development of a general framework for specifying, estimating and drawing inference regarding causally interpretable (CI) effect parameters in the 2PM context. Our proposed fully parametric 2PM (FP2PM) framework comprises very flexible versions of the EM and IM for both continuous and count-valued outcome models and encompasses all implementations of the 2PM found in the literature. Because our modeling approach is potential outcomes (PO) based, it provides a context for clear definition of targeted counterfactual CI parameters of interest. This PO basis also provides a context for identifying the conditions under which such parameters can be consistently estimated using the observable data (via the appropriately specified data generating process). These conditions also ensure that the estimation results are CI. There is substantial literature on statistical testing for model selection in the 2PM context, yet there has been virtually no attention paid to testing the “one-part” null hypothesis. Within our general modeling and estimation framework, we devise a relatively simple test of that null for both continuous and count-valued outcomes. We illustrate our proposed model, method and testing protocol in the context of estimating price effects on the demand for alcohol.

This thesis presents a method for interactive part selection for mesh and point set surface models that combines scribble-based selection methods with hierarchically accelerated graph-cut segmentation. Using graph-cut segmentation to determine optimal intuitive part boundaries enables easy part selection on complex geometries and allows for a simple, scribble-based interface that focuses on selecting within visible parts instead of precisely defining part boundaries that may be in difficult or occluded regions. Hierarchical acceleration is used to maintain interactive speeds with large models and to determine connectivity when extending the technique to point set models.

Petri nets are a graphical construction with clearly de ned semantics which can model concurrent communicating systems in a formal manner similar to the way that automata theory can model formal language theory(Petri, 1962). As Dr. Carl Petri found the existing automata insu cient or too cumbersome for describing communicating systems others have found Petri Nets to be too cumbersome for e ectively reasoning about sophisticated, real world systems. In some cases these di culties were overcome by extending the theory of Petri Nets. Dr. Kurt Jensen developed the theory of Coloured Petri Nets (Jensen, 1981) for the purpose of generalizing and simplifying complex Petri Net models. This work incorporates Coloured Petri Nets and other theoretical extensions to describe a real world automated steel cutting system. During the course of this investigation the paper will formalize colours in the language of algebras and examine patterns related to timing conditions. / Thesis / Master of Science (MSc) / Petri nets can provide a graphical explanation of computer systems that have sophisticated communications. The graph has a precise mathematical meaning which allows it to be formally analyzed to prove many interesting properites of the net. There have been many extensions of the theory, some of which are incorporated to this model of an automated steel cutting machine. This thesis also presents the idea of colours, or data types, in the language of algebras.

The aim of this study was to investigate whether there is a statistically significant difference in quality of instruction as delivered by full-time and part-time adjunct faculty in community colleges by utilizing data obtained from the Kentucky Community and Technical College (KCTCS) student evaluation of instruction instrument at Southeast Kentucky and Hazard community and technical colleges. The evaluation instrument is used to rate the instructor in the following areas: (a) clarity of course goals; (b) clarity of attendance policy; (c) examinations being a fair measure of progress; (d) clear standards of grading; (e) presentation of course material; (f) clear and to the point explanations of concepts; (g) instructor?s enthusiasm towards subject material; (h) instructor?s concern for student progress in the course; (i) instructor availability before and after class; (j) the instructor?s teaching methods promote interest in the subject area; (k) how much the course has taught the student about the subject; (l) syllabus detailing course requirements and policies was provided and explained; (m) class starts on time and as scheduled; (n) instructor meets the class for the full-time scheduled. SPSS version 14.0 was used in this project. Cross tabulations were performed for each question in the evaluation. Group statistics were computed for the data providing the means, standard deviation, and standard error of the mean for each question. Independent sample tests were also performed, including Levene?s test for equality of variances and T tests for equality of means. The findings of the study indicate that there was no statistically significant difference in student satisfaction in classes taught by adjunct (part-time) instructors and full-time instructors. Discussion of the findings and theoretical and policy implications were offered.
