Simulation Of Navigation Process Based On Nonlinear Observer, Zhiwei Wang, Jizong Hu, Fengjie Wang, Jie Huang
Journal of System Simulation
Abstract: In order to solve the problem that the scope of using thetraditional observers is limited by assumptions, in the process of establishing the observer, a parameter projection relationship is designed and added to the observer to keep it under the condition of not being constrained by the assumptions. It is semi-globally stable, and the estimation process is more direct, which makes the parameter estimation process under nonlinear conditions converge faster. The simulation results show that the computational complexity of the nonlinear observer is reduced by nearly 80% compared with the multiplicative extended Kalman filter. The experimental results show that …

Defensive Industrial Policy: Cybersecurity Interventions To Reduce Intellectual Property Theft, Dr. Chad Dacus, Dr. Carl (Cj) Horn
Military Cyber Affairs
Through cyber-enabled industrial espionage, China has appropriated what Keith Alexander, the former Director of the National Security Agency, dubbed “the largest transfer of wealth in history.” Although China disavows intellectual property (IP) theft by its citizens and has set self-sustained research and development as an important goal, it is unrealistic to believe IP theft will slow down meaningfully without changing China’s decision calculus. China and the United States have twice agreed, in principle, to respect one another’s IP rights. However, these agreements have lacked any real enforcement mechanism, so the United States must do more to ensure its IP is …

Mineta Transportation Institute
The ever-evolving technology interwoven into the transportation industry leaves it frequently at risk for cyber-attacks. This study analyzes the security of a common in-vehicle network, the Controller Area Network (CAN), standard in most vehicles being manufactured today. Like many other networks, CAN comes with inherent vulnerabilities that leave CAN implementations at risk of being targeted by cybercriminals. Such vulnerabilities range from eavesdropping, where the attacker can read the raw data traversing the vehicle, to spoofing, where the attacker can place fabricated traffic on the network. The research team initially performed a simulation of CAN traffic generation followed by hardware implementation …

Permaculture As An Ecopedagogy Curriculum And Alternative Theory Of Development : An Exploration Of The Ecological Consciousness Of Rural Western Kenyan Farmers Using Photo-Voice With A Farmer Field School During Covid-19, David Yisrael Epstein
Legacy Theses & Dissertations (2009 - 2024)
This dissertation explores two main questions of farmers in Western Kenya – how they see farming as a creative process and their role in that – and how change is made possible in their community. I explore stories from farmers themselves, using photographs they have taken and stories they tell about those photographs, which answer these two questions. In doing so, I attempt to understand the degree to which collective action has taken root in a community exposed to a permaculture based curriculum within a farmer field school. It also importantly seeks to understand what happens when such a curriculum …

Complex System Governance Leadership, David C. Walters
Engineering Management & Systems Engineering Theses & Dissertations
The purpose of this research was to develop a systems theory-based framework for leadership in governance of complex systems. Recognizing complexity and uncertainty as norms for the environments in which organizations exist encouraged researchers to suggest complexity theory, complex systems, and complex adaptive systems as appropriate for addressing these conditions. Complex System Governance (CSG), based in systems theory, management cybernetics, and governance, endeavors to provide for the design, execution and evolution of functions that provide control, communication, coordination, and integration at the metasystem level to support operations and continued system existence (viability). From a management cybernetics perspective, CSG leadership has …

Chen-Fliess Series For Linear Distributed Systems, Natalie T. Pham
Electrical & Computer Engineering Theses & Dissertations
Distributed systems like fluid flow and heat transfer are modeled by partial differential equations (PDEs). In control theory, distributed systems are generally reformulated in terms of a linear state space realization, where the state space is an infinite dimensional Banach space or Hilbert space. In the finite dimension case, the input-output map can always be written in terms of a Chen-Fliess functional series, that is, a weighted sum of iterated integrals of the components of the input function. The Chen-Fliess functional series has been used to describe interconnected nonlinear systems, to solve system inversion and tracking problems, and to design …

I am Juan Sebastian Bohorquez Mora, I am a sophomore student at Toms River High School North. I am interested in biofuels because I believe they are a good option to replace fossil fuels. I am also interested in duckweed because biofuels are made out of crops, and people need to eat those crops. That’s when duckweed comes in and it can be used as a feedstock for ethanol production which is a biofuel. Bioethanol is a type of biofuel and it is derived from the corn’s starch. Instead of making ethanol from the corn’s starch, we can use duckweed …

Abstract: With the development of affective computing, the correlation of memory, individuation and emotion is more and more important. Focus on the machine emotion shortcomings in the perception, understanding and expression, an emotion computing model integrating the emotion perception, understanding and expression is proposed. The model is a memory-oriented deep network perception model that accepts multiple modal inputs (visual, auditory, lexical) and applies a fuzzy emotion integration decision to realize the understanding of uncertain emotions. The simulation experiments prove that the model has a good performance in all kinds of multimodal affective computing.
