The First World Trade Center Project: A Historical Tribute to a Great Mega Project

The tragic collapse of the World Trade Center on September 11, 2001 could not erase the memory of one of the most successful projects in history. The project set standards of excellence in project management for years to come. Using a retrospective look at the construction management of the WTC during the 1960s and 1970s, we show how the vision of great leadership and a determined organization transformed the economy of one of the most important cities in the world

From the Reich to the Republic: The Spanish Civil War and the German Antifascist Movement, 1936-1939

Archival research for this thesis was made possible by generous grants from the Ohio State University Honors College and the German Academic Exchange Service (DAAD).The Spanish Civil War, though one of the most brutal modern conflicts and the first truly internationalized civil war of its scale, is typically seen as an aside to the Second World War. However, the war had important implications on German domestic politics. This work examines a lesser-told side of German involvement in the Spanish Civil War. While the existing literature tends to focus on the German government’s role in the war, the intersection of the two countries’ antifascist resistance efforts raises interesting questions in its own right. Rather than examining the role that German antifascists played in the Spanish Civil War, this thesis discusses the role that the war played on German antifascism. In doing so, it aims to build upon the literature on the German left in the Spanish Civil War. More broadly, this work provides a nuanced alternative to the literature on German antifascism during the period of National Socialism that includes both the top and bottom of the political hierarchy.No embargoAcademic Major: GermanAcademic Major: Histor

Attitude identification for SCOLE using two infrared cameras

An algorithm is presented that incorporates real time data from two infrared cameras and computes the attitude parameters of the Spacecraft COntrol Lab Experiment (SCOLE), a lab apparatus representing an offset feed antenna attached to the Space Shuttle by a flexible mast. The algorithm uses camera position data of three miniature light emitting diodes (LEDs), mounted on the SCOLE platform, permitting arbitrary camera placement and an on-line attitude extraction. The continuous nature of the algorithm allows identification of the placement of the two cameras with respect to some initial position of the three reference LEDs, followed by on-line six degrees of freedom attitude tracking, regardless of the attitude time history. A description is provided of the algorithm in the camera identification mode as well as the mode of target tracking. Experimental data from a reduced size SCOLE-like lab model, reflecting the performance of the camera identification and the tracking processes, are presented. Computer code for camera placement identification and SCOLE attitude tracking is listed

Evaluation of inertial devices for the control of large, flexible, space-based telerobotic arms

Inertial devices, including sensors and actuators, offer the potential of improving the tracking of telerobotic commands for space-based robots by smoothing payload motions and suppressing vibrations. In this paper, inertial actuators (specifically, torque-wheels and reaction-masses) are studied for that potential application. Batch simulation studies are presented which show that torque-wheels can reduce the overshoot in abrupt stop commands by 82 percent for a two-link arm. For man-in-the-loop evaluation, a real-time simulator has been developed which samples a hand-controller, solves the nonlinear equations of motion, and graphically displays the resulting motion on a computer workstation. Currently, two manipulator models, a two-link, rigid arm and a single-link, flexible arm, have been studied. Results are presented which show that, for a single-link arm, a reaction-mass/torque-wheel combination at the payload end can yield a settling time of 3 s for disturbances in the first flexible mode as opposed to 10 s using only a hub motor. A hardware apparatus, which consists of a single-link, highly flexible arm with a hub motor and a torque-wheel, has been assembled to evaluate the concept and is described herein

The Role of Subproject Task-Specific Attributes in Managing Enterprise-Wide Projects

Realizing that different types of projects require different styles of management is becoming part of the mainstream theory and practice in project management. This paper addresses the question of whether the same notion is also applicable to the subproject level, and how. We suggest that a project’s building blocks exhibit unique characteristics with respect to two major dimensions: Challenge (or difficulty) and vitality (or importance). Specifically, we add to the critical path and critical chain project management concepts a critical component—a unit at the sub-project level that is exceptionally risky to a project’s success. We lay out the conceptual framework in which critical component is embedded and demonstrate the theoretical and managerial aspects of contingency at the subproject level by analyzing three case studies

Towards the development of a methodology for managing industrialization projects

This paper proposes an approach for developing a project management methodology to be applied on the specific context of industrialization projects. This particular type of projects comprise the development of manufacturing lines for products, the quality of the product itself being assessed the whole way through using the well-known stage-gate system (quality gates). Project management should then support the technical activities, but its role is sometimes not so clear. In this sense, the proposed approach for developing the project management methodology is intended to solve this issue, comprising the required steps for performing a detailed characterization of the current scenario, allowing for inconsistences to be noticed and improvements to be identified.This research is sponsored by the Portugal Incentive System for Research and Technological Development.

Acids Extraction from Vegetable Oils for Acid Value pH-metric Determination without Titration

Theoretical and experimental analysis of free fatty acids extraction from vegetable oils into a reagent containing triethanolamine for pH-metric acid value determination without titration was carried out. Practically complete extraction of the free fatty acids in the form of triethanolammonium salts was demonstrated. The obtained results allow to understand more possibilities of the pH-metric and other methods for acid value determination in different oils

A steerable/distance enhanced penetrometer delivery system: Phase I. Topical report, August 1994--August 1995

The characterization, monitoring, and remediation of many of the nation`s highly contaminated sites are among the highest priorities of the Department of Energy (DOE). In underground contaminated sites, detection and mapping of the plume of contamination and in-situ remediation are the first steps towards clean up. The needs for these steps include a depth capability ranging from tens of feet to between 100 to 200 feet, ability to go around underground obstacles with curvatures that do not damage downhole components, and downhole access for delivery of environmental sensors. In addition, in some instances it is necessary to use light weight equipment over underground storage tanks in order to avoid collapse of the tank. Baseline technologies of {open_quotes}aim and shoot{close_quotes} well drilling do not satisfy all of these needs, are not as efficient, and can further contaminate the site by bringing underground contaminants to the surface. As a result new technologies are needed to carry out underground site clean up more efficiently. This report describes phase I of the development of a device for the control and penetration of penetrometers termed the Position Location Device (POLO). Work consisted of the design of steering components and vibratory penetration components
