The Effect Of Store-To-Store Energy Transfers On The Global Dynamics Of Aircraft, Guilherme Mainieri Eymael, Keegan J. Moore

This study analyzes the energy transfer mechanisms when nonlinear devices (stores) are attached to a linear model airplane. For that, a reduced-order model (ROM) was derived to simulate the first two flexible modes of vibration of the primary structure (aircraft) with one store in each wing. Each store can either be locked or unlocked. When locked, it only contributes as mass-effect, and when unlocked, it adds nonlinearity to the system. Simulations were then performed with either both stores locked, one store unlocked, or both stores unlocked. It was found that the attachment of nonlinear stores in the ROM changes the …

Drone Journalism Lab Operations Manual, Matt Waite, Ben Kreimer
College of Journalism and Mass Communications: Faculty Publications
This text is a guide for safely conducting drone journalism field work. It takes into account America's current drone regulations, our understanding of the public's acceptance of drones, the state of drone technologies, and our own experiences. The number one goal of any drone journalism operation is safety. At no time should safety be compromised. If there is any doubt, return the drone, also known as an unmanned aerial system (UAS), to the landing zone and terminate the flight. Ethical journalism is responsible journalism, and flying a drone means taking responsibility for the safety of those near you, on the …

Autonomous Capabilities For Small Unmanned Aerial Systems Conducting Radiological Response: Findings From A High-Fidelity Discovery Experiment, Brittany Duncan, Robin Murphy
School of Computing: Faculty Publications
This article presents a preliminary work domain theory and identifies autonomous vehicle, navigational, and mission capabilities and challenges for small unmanned aerial systems (SUASs) responding to a radiological disaster. Radiological events are representative of applications that involve flying at low altitudes and close proximities to structures. To more formally understand the guidance and control demands, the environment in which the SUAS has to function, and the expected missions, tasks, and strategies to respond to an incident, a discovery experiment was performed in 2013. The experiment placed a radiological source emitting at 10 times background radiation in the simulated collapse of …
Design And Development Of A Low-Cost High Range Resolution X-Band Radar, Paul C. Cantu
Design And Development Of A Low-Cost High Range Resolution X-Band Radar, Paul C. Cantu
Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research
Synthetic Aperture Radar (SAR) is one of the main tools for microwave remote sensing because of its multi-dimensional high resolution characteristics and the capability to operate in nearly all weather conditions, day and night. The University of Nebraska-Lincoln (UNL) initiated the design and development of a low-cost airborne SAR in January 2001 to support our Airborne Remote Sensing Program. The objectives of this project are separated into various evolutionary stages. This thesis will focus on the initial phase of design and construction of an X-band high range resolution radar (HRR) using basic RF /microwave and digital components. The following stages …
