Assessing Organization Culture Readiness for Knowledge Management Implementation: The Case of Aeronautical Systems Center Directorate of Contracting

The DoD is currently pursuing a wholesale transformation that impacts all facets of DoD operations and responsibilities. At the same time, the commercial sector has been experiencing significant changes that drive them to look for new ways of remaining competitive and profitable. Leveraging knowledge (intellectual capital) to increase efficiency and effectiveness within the organization has become a popular management technique that has been successful in many commercial firms. The DoD has noted the commercial sector successes and initiatives to better manage knowledge are being developed and implemented on an enterprise-wide basis as well as on a local- organizational basis. Previous research suggests that an organization\u27s readiness for change is a critical factor in whether or not implementation of knowledge management projects is successful. The previous research also suggests that readiness for change is determined by change content, process, context, and individual variables. This thesis focuses on measuring readiness for change within the Contracting Directorate at Aeronautical Systems Center (ASC/PK) located at Wright-Patterson AFE, Ohio and whether or not there are any demographic correlations to readiness for change within the organization. ASC/PK\u27s readiness for change was measured using a cross- sectional survey methodology and the results suggest that the ASC/PK population is generally ready for change in regard to knowledge management initiatives; however, several areas have been highlighted for improvement to increase overall readiness. Furthermore, the results of the study do not suggest any demographic correlations

Traumatic Brain Injury: Informed Accommodation in the Classroom

This paper discusses traumatic brain injury (TBI) and the symptoms that affect a student emotionally, cognitively and socially after experiencing a TBI. Traumatic brain injuries can have a profoundly negative impact on a child’s ability to learn at school and interact with peers in social situations. Recent research shows how TBI affects brain function and the impacts that this can have on education. However, research also suggests effective strategies that teachers can use in their classroom when teaching a student who has experienced a TBI

Modular Series-Stacked Bidirectional AC/DC Architecture for 3-Phase Grid-Tied Applications

As the concern for climate change increases, methods to reduce greenhouse gas emissions have become a priority. The transportation sector has been identified as a major source of greenhouse gas emission and is therefore a target for improvement. Specifically, vendors have promised to replace conventional internal combustion engine vehicles (ICEs) with battery electric vehicles (BEVs/EVs) or fuel cell electric vehicles (FCEVs) in the coming decades. Such a massive paradigm shift places significant demand on the electrical grid as alternatives like hydrogen pumps and EV chargers continue to replace existing gas stations. As the demands of systems such as power-to-hydrogen (P2H) and extreme fast charging (XFC) increase, there is a need for highly efficient, customizable, and scalable grid-tied power electronics that can be deployed rapidly. Conventional architectures that utilize line frequency transformers and low frequency buses pose many issues when it comes to efficiency, scaleability, lead times, and cost. This thesis presents a bidirectional converter architecture comprised of stackable three-phase ac/dc converter modules, scalable to high-power and high-current applications. Multiple converter modules containing a converter power stage and controls can be stacked to obtain a medium-voltage ac (MVAC) tied system without the need for a line frequency transformer. The modular system architecture is made possible by a quadruple active bridge (QAB) dc/dc converter that provides isolation between each of the three ac-side phases within each module and the dc load. The system also removes the need for bulk energy storage by taking advantage of constant balanced three-phase power flow. Decentralized module-level controllers are also implemented to allow for system modularity and scalability. The proposed architecture is validated by simulations of a P2H system consisting of 18 modules and a scaled proof-of-concept hardware prototype consisting of two modules.</p

Hybrid world object tracking for a virtual teaching agent

Fast algorithms and heuristics for real-time object recognition and tracking have enabled a new hybrid world technology in which one can manipulate a real world object and have its virtual world counterpart move correspondingly. This technology has been developed as part of a teaching head platform that was initially designed for language teaching but is now also being used in a range of health-oriented contexts. In this paper, the requirements of the technology are motivated and elucidated, with direct comparison of our proposed heuristics with well known object recognition algorithms

Minuteman 2 launched small satellite

The goal of LEOSat Industries' Spring 1994 project was to design a small satellite that has a strong technology demonstration or scientific justification and incorporates a high level of student involvement. The satellite is to be launched into low earth orbit by the converted Minuteman 2 satellite launcher designed by Minotaur Designs, Inc. in 1993. The launch vehicle shroud was modified to a height of 90 inches, a diameter of 48 inches at the bottom and 35 inches at the top for a total volume of 85 cubic feet. The maximum allowable mass of the payload is about 1100 lb., depending on the launch site, orbit altitude, and inclination. The satellite designed by LEOSat Industries is TerraSat, a remote-sensing satellite that will provide information for use in space-based earth studies. It will consist of infrared and ultraviolet/visible sensors similar to the SDI-developed sensors being tested on Clementine. The sensors will be mounted on the Defense Systems, Inc. Standard Satellite-1 spacecraft bus. LEOSat has planned for two satellites orbiting the Earth with trajectories similar to that of LANDSAT 5. The semi-major axis is 7080 kilometers, the eccentricity is 0, and the inclination is 98.2 degrees. The estimated mass of TerraSat is 145 kilograms and the estimated volume is 1.8 cubic meters. The estimated cost of TerraSat is $13.7 million. The projected length of time from assembly of the sensors to launch of the spacecraft is 13 months
