Modeling The Impact Of The Payload Alert Communications System (Pacs) On The Accuracy Of Conjunction Analysis, Landon B. Bastow
Modeling The Impact Of The Payload Alert Communications System (Pacs) On The Accuracy Of Conjunction Analysis, Landon B. Bastow
Theses and Dissertations
The Air Force Institute of Technology (AFIT) and the Air Force Research Laboratory (AFRL) are jointly developing a system known as the Payload Alert Communications System (PACS) whose purpose is to decrease the statistical uncertainty in the location of resident space objects (RSOs). PACS is designed to augment the Joint Space Operations Center's (JSpOC) existing space object tracking capabilities which is expected to increase the accuracy of conjunction estimation. In the current PACS design, a small payload would be attached to certain RSOs prior their launch. It is envisioned that this payload would basically consist of a microcontroller, a Global …
Applying Hyperspectral Imaging To Heart Rate Estimation For Adaptive Automation, Joshua M. Splawn
Applying Hyperspectral Imaging To Heart Rate Estimation For Adaptive Automation, Joshua M. Splawn
Theses and Dissertations
Automation use continues to increase in Air Force systems with the goal of improving operator efficiency and effectiveness. Unfortunately, systems are often complex, potentially imposing increased mental task load on the operator, or placing the operator in a supervisory role where they can become dependent on automation. Adaptive automation is a proposed solution, where automation is triggered when an operator is overloaded, and disabled as the operator is underloaded. Changes in physiological measures have shown promise in triggering automation. Unfortunately heart rate measurement can be obtrusive and impractical in day-to-day operations. This research used the Air Force Multi-Attribute Task Battery …
Evaluating The Effect Of Integrated System Health Management On Mission Effectiveness, Sarah E. Storm
Evaluating The Effect Of Integrated System Health Management On Mission Effectiveness, Sarah E. Storm
Theses and Dissertations
This research used systems architecture to develop a model that determined the effect of Integrated System Health Management (ISHM) on mission success rates for unmanned aerial systems (UAS). To evaluate this effect, a simulation model was developed and used to analyze the difference between mission success rates for a theoretical UAS with and without ISHM. Design of Experiments analysis techniques were used to map a response surface that modeled the difference between mission success rates calculated for current health management technology and ISHM. Using representative data for a UAS, the analysis determined that the failure distribution parameters, sensor quality (which …
Identifying System Patterns To Resolve Challenges In The Test And Evaluation Operation, Daniel K. Mutunga
Identifying System Patterns To Resolve Challenges In The Test And Evaluation Operation, Daniel K. Mutunga
Theses and Dissertations
This research focuses on identification and description of patterns used in Test and Evaluation (T&E) operations. Patterns are defined as named and well-known problem/solution pairs that can be applied in new contexts, with advice on how to apply it in a novel situations and discussion of its trade-offs, implementations, and variations. They have a well established and used in software engineering, but have only recently been considered for systems engineering. In the Department of Defense (DOD), T&E is required for all acquisitions prior to transitioning into operations. As identified and described in this thesis, each of the patterns fits in …
The Use Of Multi-Criteria Evaluation And Network Analysis In The Area Development Planning Process, Peeter E. Pleake-Tamm
The Use Of Multi-Criteria Evaluation And Network Analysis In The Area Development Planning Process, Peeter E. Pleake-Tamm
Theses and Dissertations
The purpose of this research was to develop improvements to the area development planning process. These plans are used to improve operations within an installation sub-section by altering the physical layout of facilities. One methodology was developed based on apply network analysis concepts to the generation of alternative facility layouts. A second methodology was developed using multi-criteria evaluation to the selection of evaluated alternative facility layouts. The results of this study are two methodological processes that can be executed at base level requiring minimal additional information. The functional network map, based in network analysis, increases the use of socio-economic data …
An Evaluation Of The Organizational Structure Of Air Force Emergency Operations Centers Using Social Network Analysis And Design Structure Matrices, John W. Marshall
An Evaluation Of The Organizational Structure Of Air Force Emergency Operations Centers Using Social Network Analysis And Design Structure Matrices, John W. Marshall
Theses and Dissertations
The terrorist attacks on September 11, 2001 demonstrated that the United States' emergency response capability, while robust, was disorganized in that organizations were not prepared or equipped to coordinate response actions across multiple agencies at a national level. This research investigates whether NIMS and the AFIMS structure is optimal for Air Force emergency managers, or whether, while maintaining NIMS compliance, there is a more effective way for the Air Force to organize its emergency management and response forces. Specifically this research focuses on the organization of the EOC and investigates whether shifting from the current structure of the ESFs to …
Using Value-Focused Thinking As An Alternative Means Of Opportunity Assessment For Strategic Sourcing Applications, Andrew R. Myers
Using Value-Focused Thinking As An Alternative Means Of Opportunity Assessment For Strategic Sourcing Applications, Andrew R. Myers
Theses and Dissertations
In recent years, the Federal Government has attempted to utilize strategic sourcing to reduce acquisitions expenses. Currently accepted best practices for strategic sourcing developed in the private sector fail to account for the diverse and unique set of objectives present in public sector acquisitions. Value Focused Thinking was used to develop a hierarchy of values and objectives for the Air Force Civil Engineer Commodity Council (CECC) strategic sourcing program. This hierarchy represents the full range of program objectives, and was used to develop a value function useful for systematically evaluating service and commodity contract areas for strategic sourcing potential.
An Investigation And Analysis Of The Vestibulo-Ocular Reflex In A Vibration Environment, Daniel J. Uribe
An Investigation And Analysis Of The Vestibulo-Ocular Reflex In A Vibration Environment, Daniel J. Uribe
Theses and Dissertations
Forty years of innovations have greatly improved Helmet-Mounted Displays (HMDs) and their integration into military systems. However, a significant issue with HMDs is the effect of vibration and the associated Vestibulo-Ocular Reflex (VOR). When a human’s head is subject to low-frequency vibration, the VOR stabilizes the eye with respect to objects in the external environment. However, this response is inappropriate in HMDs as the display moves with the user’s head and the VOR blurs the image as it is projected on the human retina. Current compensation techniques suggest increasing the size of displayed graphics or text to compensate for the …
Calibration And Extension Of A Discrete Event Operations Simulation Modeling Multiple Un-Manned Aerial Vehicles Controlled By A Single Operator, Jonathan W. Welborn
Calibration And Extension Of A Discrete Event Operations Simulation Modeling Multiple Un-Manned Aerial Vehicles Controlled By A Single Operator, Jonathan W. Welborn
Theses and Dissertations
This research improved a simulation that models a single operator responsible for multiple UAV rovers. The improvement calibrated the model by increasing the realism of its expected time that the target will be within the field of view of a UAV's camera and how much of that will be observed by an operator that has multiple tasks to perform throughout the mission. The calibration was derived from multiple flight tests, by using a Field of View Algorithm in MATLAB and by visually recording times for loiter loops by hand. It was determined that the target will be within the field …
