Space Operations In The Suborbital Space Flight Simulator And Mission Control Center: Lessons Learned With Xcor Lynx, Pedro Llanos, Christopher Nguyen, David Williams, Kim O. Chambers Ph.D., Erik Seedhouse, Robert Davidson

Pedro J. Llanos (www.AstronauticsLlanos.com)

This study was conducted to better understand the performance of the XCOR Lynx vehicle. Because the Lynx development was halted, the best knowledge of vehicle dynamics can only be found through simulator flights. X-Plane 10 was chosen for its robust applications and accurate portrayal of dynamics on a vehicle in flight. The Suborbital Space Flight Simulator (SSFS) and Mission Control Center (MCC) were brought to the Applied Aviation Sciences department in fall 2015 at Embry-Riddle Aeronautical University, Daytona Beach campus. This academic and research tool is a department asset capable of providing multiple fields of data about suborbital simulated flights. …

Heteroclinic And Homoclinic Connections Between The Sun-Earth Triangular Points And Quasi-Satellite Orbits For Solar Observations, Pedro J. Llanos, Gerald R. Hintz, Martin W. Lo, James K. Miller

Pedro J. Llanos (www.AstronauticsLlanos.com)

Investigation of new orbit geometries exhibits a very attractive behavior for a spacecraft to monitor space weather coming from the Sun. Several orbit transfer mechanisms are analyzed as potential alternatives to monitor solar activity such as a sub-solar orbit or quasi-satellite orbit and short and long heteroclinic and homoclinic connections between the triangular points L4 and L5 and the collinear point L3 of the CRTBP (circular restricted three-body problem) in the Sun-Earth system. These trajectories could serve as channels through where material can be transported from L5 to L3 by performing small maneuvers at the departure of the Trojan orbit. …

Towards Trustworthy Coordination For Web Services Business Activities, Hua Chai, Hongle Zhang, Wenbing Zhao, P. M. Melliar-Smith, L. E. Moser

Wenbing Zhao

We present a lightweight Byzantine fault tolerance (BFT) algorithm, which can be used to render the coordination of web services business activities (WS-BA) more trustworthy. The lightweight design of the BFT algorithm is the result of a comprehensive study of the threats to the WS-BA coordination services and a careful analysis of the state model of WS-BA. The lightweight BFT algorithm uses source ordering, rather than total ordering, of incoming requests to achieve Byzantine fault tolerant, state-machine replication of the WS-BA coordination services. We have implemented the lightweight BFT algorithm, and incorporated it into the open-source Kandula framework, which implements …

Spe: Security And Privacy Enhancement Framework For Mobile Devices, Brian Krupp, Nigamanth Sridhar, Wenbing Zhao

Wenbing Zhao

In this paper, we present a security and privacy enhancement (SPE) framework for unmodified mobile operating systems. SPE introduces a new layer between the application and the operating system and does not require a device be jailbroken or utilize a custom operating system. We utilize an existing ontology designed for enforcing security and privacy policies on mobile devices to build a policy that is customizable. Based on this policy, SPE provides enhancements to native controls that currently exist on the platform for privacy and security sensitive components. SPE allows access to these components in a way that allows the framework …

Low Latency Fault Tolerance System, Wenbing Zhao, P. M. Melliar-Smith, L. E. Moser

Wenbing Zhao

The Low Latency Fault Tolerance (LLFT) system provides fault tolerance for distributed applications within a local-area network, using a leader-follower replication strategy. LLFT provides application-transparent replication, with strong replica consistency, for applications that involve multiple interacting processes or threads. Its novel system model enables LLFT to maintain a single consistent infinite computation, despite faults and asynchronous communication. The LLFT Messaging Protocol provides reliable, totally-ordered message delivery by employing a group multicast, where the message ordering is determined by the primary replica in the destination group. The Leader-Determined Membership Protocol provides reconfiguration and recovery when a replica becomes faulty and when …

Concurrent Byzantine Fault Tolerance For Software-Transactional-Memory Based Applications, Honglei Zhang, Wenbing Zhao

Wenbing Zhao

Typical Byzantine fault tolerance algorithms require the application requests to be executed sequentially, which may severely limit the throughput of the system considering that modern CPUs are equipped with multiple processing cores. In this paper, we present the design and implementation of a Byzantine fault tolerance framework for software-transactional-memory based applications that aims to maximize concurrent processing while preserving strong replica consistency. The approach is based on the idea of committing concurrent transactions according to the total order of the requests that triggered the transactions. A comprehensive performance evaluation is carried out to characterize the effectiveness and limitations of this …

High Consequence Scenarios For North Korean Atmospheric Nuclear Tests With Policy Recommendations For The U.S. Government, Thomas S. Popik, Jordan T. Kearns, George H. Baker Iii, Henry F. Cooper, William R. Harris

George H Baker

The government of North Korea has declared high-altitude EMP-capability to be a “strategic goal” and has also threatened an atmospheric test of a hydrogen bomb. Atmospheric nuclear tests have the potential to cripple satellites and the undersea cable networks critical to communication, and navigation necessary for trans-Pacific trade among the U.S., China, and other nations. When a nuclear warhead is detonated at high altitude, a series of electromagnetic pulses radiate downward within the line of sight of the blast. These pulses can disable equipment with miniature electronics and long conductors. Electric grid controls and transmission systems are especially vulnerable. Intense …

Synthetic Jet Actuator-Based Aircraft Tracking Using A Continuous Robust Nonlinear Control Strategy, N. Ramos-Pedroza, W. Mackunis, M. Reyhanoglu

William MacKunis

A robust nonlinear control law that achieves trajectory tracking control for unmanned aerial vehicles (UAVs) equipped with synthetic jet actuators (SJAs) is presented in this paper. A key challenge in the control design is that the dynamic characteristics of SJAs are nonlinear and contain parametric uncertainty. The challenge resulting from the uncertain SJA actuator parameters is mitigated via innovative algebraic manipulation in the tracking error system derivation along with a robust nonlinear control law employing constant SJA parameter estimates. A key contribution of the paper is a rigorous analysis of the range of SJA actuator parameter uncertainty within which asymptotic …

3d Multilevel Spin Transfer Torque Devices, J. Hong, M. Stone, K. Luongo, Q. Zheng, Z. Yuan, K. Xia, N. Xu, L. You, Sakhrat Khizroev

Sakhrat Khizroev

Spin-transfer torque magnetic tunneling junction devices capable of a multilevel three-dimensional (3D) information processing are studied in the sub-20-nm size range. The devices are built using He⁺ and Ne⁺ focused ion beam etching. It has been demonstrated that due to their extreme scalability and energy efficiency, these devices can significantly reduce the device footprint compared to the modern CMOS approaches and add advanced features in a 3D stack with a sub-20-nm size using a spin polarized current.

Reconfigurable And Non-Volatile Vertical Magnetic Logic Gates, J. Butler, M. Shachar, B. Lee, D. Garcia, B. Hu, J. Hong, N. Amos, Sakhrat Khizroev

Sakhrat Khizroev

In this paper, we discuss the concept and prototype fabrication of reconfigurable and non-volatile vertical magnetic logic gates. These gates consist of two input layers and a RESET layer. The RESET layer allows the structure to be used as either an and or an or gate, depending on its magnetization state. To prove this concept, the gates were fabricated using a multi-layered patterned magnetic media, in which three magnetic layers are stacked and exchange-decoupled via non-magnetic interlayers. We demonstrate the functionality of these logic gates by conducting atomic force microscopy and magnetic force microscopy (MFM) analysis of the multi-layered patterned …

Physics Considerations In Targeted Anticancer Drug Delivery By Magnetoelectric Nanoparticles, Emmanuel Stimphil, Abhignyan Nagesetti, Rakesh Guduru, Tiffanie Stewart, Alexandra Rodzinski, Piang Liang, Sakhrat Khizroev

Sakhrat Khizroev

In regard to cancer therapy, magnetoelectric nanoparticles (MENs) have proven to be in a class of its own when compared to any other nanoparticle type. Like conventional magnetic nanoparticles, they can be used for externally controlled drug delivery via application of a magnetic field gradient and image-guided delivery. However, unlike conventional nanoparticles, due to the presence of a non-zero magnetoelectric effect, MENs provide a unique mix of important properties to address key challenges in modern cancer therapy: (i) a targeting mechanism driven by a physical force rather than antibody matching, (ii) a high-specificity delivery to enhance the cellular uptake of …

Multilevel-3d Bit Patterned Magnetic Media With 8 Signal Levels Per Nanocolumn, Nissim Amos, John Butler, Beomseop Lee, Meir H. Shachar, Bing Hu, Yuan Tian, Jeongmin Hong, Davil Garcia, Rabee M. Ikkawi, Robert C. Haddon, Dmitri Litvinov, Sakhrat Khizroev

Sakhrat Khizroev

This letter presents an experimental study that shows that a 3^rd physical dimension may be used to further increase information packing density in magnetic storage devices. We demonstrate the feasibility of at least quadrupling the magnetic states of magnetic-based data storage devices by recording and reading information from nanopillars with three magnetically-decoupled layers. Magneto-optical Kerr effect microscopy and magnetic force microscopy analysis show that both continuous (thin film) and patterned triple-stack magnetic media can generate eight magnetically-stable states. This is in comparison to only two states in conventional magnetic recording. Our work further reveals that ferromagnetic interaction between magnetic …

Multiferroic Coreshell Magnetoelectric Nanoparticles As Nmr Sensitive Nanoprobes For Cancer Cell Detection, Abhignyan Nagesetti, Alexandra Rodzinski, Emmanuel Stimphil, Tiffanie Stewart, Chooda Khanal, Ping Wang, Rakesh Guduru, Ping Liang, Irina U. Agoulnik, Jeffrey Horstmyer, Sakhrat Khizroev

Sakhrat Khizroev

Magnetoelectric (ME) nanoparticles (MENs) intrinsically couple magnetic and electric fields. Using them as nuclear magnetic resonance (NMR) sensitive nanoprobes adds another dimension for NMR detection of biological cells based on the cell type and corresponding particle association with the cell. Based on ME property, for the first time we show that MENs can distinguish different cancer cells among themselves as well as from their normal counterparts. The core-shell nanoparticles are 30 nm in size and were not superparamagnetic. Due to presence of the ME effect, these nanoparticles can significantly enhance the electric field configuration on the cell membrane which serves …
