Show moreABSTRACT Modeling and simulation of financial instruments is accomplished from multiple approaches but most completely from an engineering perspective. Aeronautical engineering yields a wave model created for stock indices in the 1970s. This comprehensive methodology models stock markets as waves for the intention of trading or investing yet has not been applied on time periods smaller than daily or weekly, known as intraday. Stakeholders trading intraday waves need to utilize wave analysis for price capture, analytics, and profitability. It is the purpose of this thesis to present a model to harness wave analytics for the needs of traders seeking price capture of the Standard and Poor's 500 Index on an hourly and minute time periods, or intraday. This paper applies wave analytics in time frames never accomplished before for the sufficing the needs of index day traders.

Show moreThe military has used simulations to train Soldiers for several decades. Army Commanders use live, virtual and constructive training to prepare troops for combat and to improve their Military Occupational Specialty (MOS) skillset. During training and other military operations, the Army Battle Command Systems (ABCS) provide Army commanders with a Common Operational Picture (COP) which typically includes a real-time status of personnel, supplies, munitions, and equipment. In 2016, the Combined Arms Support Command (CASCOM) divested the Battle Command Sustainment Support System (BCS3) due to data latency issues. The sustainment Warfighting Function (WfF) used BCS3 as a dual-purpose system for real world operations and constructive simulation training events. The same year, the Army also streamlined its Joint Land Component Constructive Training Capability (JLCCTC) to reduce costs further limiting the usefulness of JLCCTC to train sustainment units. This study considers the suitability of the Division Exercise Training and Review System (DXTRS) to fill the sustainment training gap. A combination of face to face and telephonic interviews are conducted with Soldiers and select Department of Defense (DoD) contractors to determine the appropriateness of DXTRS for sustainment training. Interview questions designed using the Technology Acceptance Model (TAM) are used to measure DXTRS version 1.06 suitability as a sustainment training tool. Inductive thematic content analysis is used to analyze the interview transcripts and provide findings, conclusions, and recommend future research.

Show morePoor dietary choices and lack of physical activity are two main contributing factors for the increasing prevalence of overweight and obesity in the United States. Overweight and obese individuals are at risk for developing major life-threatening diseases. Weight loss is an effective means for reversing these adverse health effects, and smartphone applications (apps) may be an effective means for supporting weight loss outside of formal clinical settings. This study involved identifying factors that contribute to effective weight loss to compare with functionality commonly found in a sample of calorie counter apps. A content analysis was performed using a design framework that included a conceptual model describing the interaction of behaviors for effective weight loss and functional design requirements based upon behavior change and motivation to achieve weight loss. The requirements were used to analyze the presence of features in a sample of popular calorie counting apps, to infer their capability in supporting users' motivation to achieve weight loss. Results indicated that app features might not provide sufficient support to facilitate effective weight loss. Lack of supportive features affects perceived autonomy, relatedness, and competence, reducing motivation. This study provided guidelines to improve the design of calorie counter apps to include more features that support users as they engage in weight loss behaviors. The guidelines may become practical for use in mHealth apps used as part of formal and informal weight management strategies. Implications for future research involving wearable technologies and the use of gamified design strategies are discussed.

Show moreThe organization of Modeling and Simulation (M(&)S) as a profession started in the early twenty-first century spurred by the advent of computers and the vast networking capabilities of contemporary computing. M(&)S is still in its infancy when compared to other disciplines, such as engineering, computer science and mathematics. However, the profession has experienced significant growth in part due to the varied use of M(&)S techniques and tools within almost every discipline.Professional organizations and academic programs supporting M(&)S across the country have started to materialize. In a short timeframe, the growth of these supporting organizations has outpaced their ability to stay unified as a discipline, aligned with standardized Knowledge, Skills, and Abilities (KSAs) and with growing stakeholder needs.Consequently, there appear to be gaps in the M(&)S professional organization. Such as a lack of synchronization between the three primary stakeholder groups of the M(&)S profession: academia, government, and industry. The discipline's professional organization fails to recognize a single body of knowledge as an authoritative reference for M(&)S KSAs. Academic institutions do not have unanimity regarding targeted KSAs. Industry lacks the confidence to hire M(&)S professionals who have a core understanding of KSAs directly associated with the version of M(&)S used by each separate industry.This research study attempts to take a coordinated step forward in unifying the M(&)S discipline by assessing and prioritizing the current competencies and standards required of M(&)S professionals and identifying the needs and competencies valued by primary stakeholders. A survey instrument was developed in conjunction with Rebecca Leis' doctorate research. The instrument was distributed to M(&)S stakeholders to ascertain the breadth of the needed, valued, and required KSAs within the domain. The survey was evaluated by cross-referencing questions and tabulating responses. Results from this research suggest ways in which stakeholders can coordinate efforts in advancing the M(&)S professional organization and support a uniformed set of KSAs needed in academia, government, and industry now and in the future.

Show moreThe National Data Exchange (N-DEx) System is the central informational hub located at the Federal Bureau of Investigation (FBI). Its purpose is to provide network subscriptions to all Federal, state and local level law enforcement agencies while increasing information collaboration across all domains. The National Data Exchange users must satisfy the Advanced Permission Requirements, confirming the terms of N-DEx information use, and the Verification Requirement (verifying the completeness, timeliness, accuracy, and relevancy of N-DEx information) through coordination with the record-owning agency (Management, 2018). A network infection model is proposed to simulate the spread impact of various cyber-attacks within Federal, state and local level law enforcement networks that are linked together through the topologies merging with the National Data Exchange (N-DEx) System as the ability to manipulate the live network is limited. The model design methodology is conducted in a manner that creates a level of organization from the state level to the local level of law enforcement agencies allowing for each organizational infection probability to be calculated and entered, thus making the model very specific in nature for determining spread or outbreaks of cyber-attacks among law enforcement agencies at all levels. This research will enable future researchers to further develop a model that is capable of detecting weak points within an information structure when multiple topologies merge, allowing for more secure operations among law enforcement networks.

Show moreImprovised Explosive Devices (IEDs) are the greatest casualty producing and costly weapon system employed by the enemy on the asymmetric battlefield of today. Despite Billions of dollars spent on technological devices to counter the IED threat, IEDs are still responsible for roughly 50% of battlefield casualties. A tremendous amount of effort and resource has and continues to be levied in the pursuit of a technological solution to the IED problem. By contrast, little research has been done on Counter Improvised Explosive Device (CIED) procedures. This paper explores the potential of CIED procedures as a casualty reduction mechanism by comparing two observed tactical procedures used in patrolling convoy routes.

Show moreAs the underlying cause of Glioblastoma Multiforme (GBM) is presently unclear, this research implements a new approach to identifying and segmenting plausible instances of GBM prior to critical mass. Grade-IV Astrocytoma, or GBM, is an aggressive and malignant cancer arising from star-shaped glial cells, or astrocytes, where the astrocytes, functionally, assist in the support and protection of neurons within the central nervous system and spinal cord. Subsequently, our motivation for researching the ability to recognize GBM is that the underlying cause of the mutation is presently unclear, leading to the operative that GBM is only detectable through a combination of MRI and CT brain scans, cooperatively, along with a resection biopsy. Since astrocytoma only becomes evident at critical mass, when the cellular structure of the neoplasm becomes visible within the image, this research seeks to achieve earlier identification and segmentation of the neoplasm by evaluating the malignant area via a volumetric voxel approach to removing noise artifacts and analyzing voxel differentials. In order to investigate neoplasm continuity, a differential approach has been implemented utilizing a multi-polynomial/multi-domain regression algorithm, thus, ultimately, providing a graphical and mathematical analysis of the differentials within critical mass and non-critical mass images. Given these augmentations to MRI and CT image rectifications, we theorize that our approach will improve on astrocytoma recognition and segmentation, along with achieving greater accuracy in diagnostic evaluations of the malignant area.

Show moreThis research study sought to determine if there was any difference in the perception of training modality delivery between participants who attended a face-to-face (F2F) training session or participated in blended training that supported business intelligence (BI) technology adoption. There is minimal information available identifying how training can influence an individual's intention to fully adopt BI technology into daily work processes. Identification of key factors influencing training modalities' effect on technology adoption promotes strategies that allow trainers to better facilitate and develop content that can help organizations to integrating BI technologies into their workflow. This study analyzed survey responses that captured the perceptions of end-users who completed training by attending a F2F or blended training and their readiness to utilize the BI technologies post-training. The sample for this study consisted of 62 individuals who completed both the training session survey (F2F or blended) and the client implementation survey; to qualify for this study, all participants completed both surveys; 33 participants attended the F2F training sessions, and 29 participants attended the blended training sessions. Survey responses related to the training session and the training consultant were used to identify differences in perception when comparing the two different groups and their feelings of preparedness to accept responsibility for the technology. While there was an indication that the feeling of preparedness to adopt the BI technology was more heavily influenced by the blended training, it is important to consider methods for improving participant satisfaction in all areas related to blended training. Overall, this study provides the basis for an executive summary indicating the need to implement more effective training strategies, policies, and training processes before and after implementing BI technologies within organizations.

Show morePolitical science uses international relations (IR) theory to explain state-actor political behavior. Research suggests that this theoretical framework can inform a predictive model incorporating features of systems dynamics (SD) and agent based (AB) modeling. The Foreign Policy Model (ForPol) herein applies Alexander Y. Lubyansky's (2014) SD model for macro-political behavior to represent behaviors between real systems and mental models. While verifying and validating the resulting SD/AB/IR holistic model requires an extensive comprehensive research agenda, the present work will take a closer examination at input parameter calibration and conducting typical runs of the SD portion of the model as a first step in the testing, verification and validation process of the proposed integrative model. This thesis proposes incorporating an AB paradigm drawn from work by Claudio Cioffi-Revilla (2009), Edward P. MacKerrow (2003), David L. Rousseau (2006), Joshua M. Epstein and Robert Axtell (1996) as a future hybrid extension.The model applies a SD approach for the modeling of macro-political aggregate behavior. Therefore, the deep analysis of the SD portion of ForPol is modeled and calibrated in Vensim, using empirical data from the 1967 Arab-Israeli Six Day War as a pilot. Interactions within the model actualize Choucri, et. al. (2006), definition of state stability and agent behavior aspects of Cioffi-Revilla's (2009) SimPol polity model. Following calibration results discussion, the present work closes with consideration of future research directions.

Show moreWhen a driver turns a steering-wheel, he or she normally expects the vehicle's steering system to communicate an equivalent amount of signal to the road-wheels. This relationship is linear and occurs regardless of the steering-wheel's position within its rotational travel. The linear steering paradigm in passenger vehicles has gone largely unchanged since mass production of passenger vehicles began in 1901. However, as more electronically-controlled steering systems appear in conjunction with development of autonomous steering functions in vehicles, an opportunity to advance the existing steering paradigms arises. The following framework takes a human-factors approach toward examining and evaluating alternative steering systems by using Modeling and Simulation methods to track and score human performance.Present conventional steering systems apply a linear relationship between the steering-wheel and the road wheels of a vehicle. The rotational travel of the steering-wheel is 900(&)deg; and requires two-and-a-half revolutions to travel from end-stop to opposite end-stop. The experimental steering system modeled and employed in this study applies a dynamic curve response to the steering input within a shorter, 225(&)deg; rotational travel. Accommodation variances, based on vehicle speed and steering-wheel rotational position and acceleration, moderate the apparent steering input to augment a more-practical, effective steering rate. This novel model follows a paradigm supporting the full range of steering-wheel actuation without necessitating hand repositioning or the removal of the driver's hands from the steering-wheel during steering maneuvers.In order to study human performance disparities between novel and conventional steering models, a custom simulator was constructed and programmed to render representative models in a test scenario. Twenty-seven males and twenty-seven females, ranging from the ages of eighteen to sixty-five were tested and scored using the driving simulator that presented two successive driving test vignettes: One vignette using conventional 900(&)deg; steering with linear response and the other employing the augmented 225(&)deg; multivariate, non-linear steering.The results from simulator testing suggest that both males and females perform better with the novel system, supporting the hypothesis that drivers of either gender perform better with a system augmented with 225(&)deg; multivariate, non-linear steering than with a conventional steering system. Further analysis of the simulated-driving scores indicates performance parity between male and female participants, supporting the hypothesis positing no significant difference in driver performance between male and female drivers using the augmented steering system. Finally, composite data from written questionnaires support the hypothesis that drivers will prefer driving the augmented system over conventional steering.These collective findings support justification for testing and refining novel steering systems using Modeling and Simulation methods. As a product of this particular study, a tested and open-sourced simulation framework now exists such that researchers and automotive designers can develop, as well as evaluate their own steering-oriented products within a valid human-factors construct. The open-source nature of this framework implies a commonality by which otherwise disparate research and development work can be associated.Extending this framework beyond basic investigation to reach applications requiring more-specialized parameters may even impact drivers having special needs. For example, steering-system functional characteristics could be comparatively optimized to accommodate individuals afflicted with upper-body deficits or limited use of either or both arms. Moreover, the combined human-factors and open-source approaches distinguish the products of this research as a common and extensible platform by which purposeful automotive-industry improvements can be realized(-)contrasted with arbitrary improvements that might be brought about predominantly to showcase technological advancements.
