Methods And Techniques Used For Job Shop Scheduling, Yoo Baik Yang

Retrospective Theses and Dissertations

The job shop scheduling problem, in which we must determine the order or sequence for processing a set of jobs through several machines in an optimum manner, has received considerable attention. In this paper a number of the methods and techniques are reviewed and an attempt to categorize them according to their appropriateness for effective use in job shop scheduling has been made. Approaches are classified in two categories: a) analytical techniques and b) graphical methods. Also, it should be noticed that this report does not include all the attempts and trials, especially the heuristic approaches.

Thermal Response Of A Composite Bridge Structure, David John Wisch

Masters Theses

"This experimental investigation was conducted as an intermediate study to verify and substantiate a prior theoretical study for possible utilization toward development of rational bridge design criteria. The objectives of the study were to construct and instrument a 15 ft - 15 ft (4.6 m- 4.6 m) two-span, composite design, laboratory structure, to subject the structure to thermal loading, and to correlate the experimental temperature distributions, strain distributions, and deflections with those obtained from the theoretical study. Infrared heat lamps were used to obtain steady-state thermal loading.

Three theoretical cases were considered for strain calculations: a) both the slab and …

Dynamic Pullout Resistance Of Anchors Buried In Dry Sand, Chris John Veesaert

Masters Theses

"The vertical pullout resistance of buried anchors subjected to dynamic loading was investigated by means of a laboratory model study. A dry uniformly graded sand, compacted by vibration to 92% of its relative density, was used as the test medium. Tests were performed in a 24-inch square tank using 3.0 and 5.0-inch diameter half and full-anchors. The anchors were tested at depths ranging from 5.0 to 21.0 inches.

It was assumed that the dynamic failure mechanism of earth anchors was the same as the static failure mode, and not distinct behavior. Thus static tests, i.e., tests using a constant strain …

Removal Of Organic Chemical Contaminants By Granular Activated Carbon., Garry Reinhold Aronberg

Masters Theses

"The purpose of this investigation was to evaluate the effectiveness of GAC* filtration in removing organic chemical contaminants from drinking water, and to determine whether the T.O. No. of the treated water could aid in the routine monitoring of the GAC filters.

Two pilot filters containing 18-in. (45.7-cm) deep GAC beds were installed at water treatment plants in Jefferson City and St. Louis County, MO; both plants treated Missouri River water. A bituminous coal-base (large surface area, small pore volume) and 2 lignite coal-base (small surface area, large pore volume) carbons were tested at 2 and 5 gpm/sq ft (81.4 …

An Evaluation Of Productivity And Efficiency In Work Scheduling In A Public Works Department, Kraig L. Gordon

Masters Theses

“Managers throughout the world frequently associate the meanings of productivity and efficiency with the capabilities and performance of employees. This approach is limited since productivity entails far more than the output of the labor force. The factors affecting productivity need evaluating to determine the significance they plan in the overall process.

Industry has attempted to improve its productivity posture by utilizing a multitude of concepts. Some of these concepts are time and motion studies and process planning. However, in the public sector, literature shows that little has been attempted to improve the productivity in public organizations.

The greatest portion of …

Theoretical And Experimental Investigation Of Oil Recovery By The Electrothermic Technique, Samy Abdel-Hakeem El-Feky

Doctoral Dissertations

"This work investigates the feasibility of increasing oil recovery from petroleum reservoirs by the electrothermic technique. A mathematical model was developed for the prediction of reservoir response to heating by alternating electric current flow through the oil-bearing formations. The mathematical model was programmed in FORTRAN for solution on the IBM 370/168. The model used the finite difference technique to represent the differential equations that describe the system, and the sets of difference equations were solved by the Strongly Implicit Procedure (SIP) and Successive Overrelaxation (SOR).

In order to verify the mathematical model, a set of experiments was conducted to determine …

Effect Of Compliant Wall Motion On Turbulent Boundary Layers, Dennis M. Bushness, Jerry N. Hefner, Robert L. Ash

Mechanical & Aerospace Engineering Faculty Publications

A critical analysis of available compliant wall data which indicated drag reduction under turbulent boundary layers is presented. Detailed structural dynamic calculations suggest that the surfaces responded in a resonant, rather than a compliant, manner. Alternate explanations are given for drag reductions observed in two classes of experiments: (1) flexible pipe flows and (2) water-backed membranes in air. Analysis indicates that the wall motion for the remaining data is typified by short wavelengths in agreement with the requirements of a possible compliant wall drag reduction mechanism recently suggested by Langley.

Propagule Dispersal Among Forest Islands In Southeastern South Dakota, J. Warren Ranney, W. Carter Johnson

United States Department of Energy: Publications

The study of seed dispersal between the widely separated forest patches (forest islands) of the eastern Great Plains can contribute to understanding effects of deforestation in the more complex forest island landscapes of the eastern United States. In the East, there is growing concern that the dissection of regional forests and the creation of small forest islands surrounded by non-forest uses (e.g., agriculture) may be affecting plant species richness and developmental patterns of vegetation (Levenson 1976), as has already been noted in the tropics (Gomezpompa et al. 1972). Curtis (1956) showed that the presettlement forest area in a portion of …
