Ramping Down Chinese Commercial Cyber Espionage, Emilio Iasiello
Ramping Down Chinese Commercial Cyber Espionage, Emilio Iasiello
Emilio Iasiello
While detractors believe that commercial cyber espionage hasn’t really stopped, recent Chinese efforts show a government trying to get a handle on its large spying apparatus that could include hired and independent contractors acting autonomously in addition to its other resources. While complete cessation may never occur, significant timely reduction demonstrates Beijing’s willingness to work with the United States as a partner and not a pariah, and provides a foundation from which the two governments can move forward on other cyber security areas where incongruity persists.
Quasi-Platonic Psl2(Q)-Actions On Closed Riemann Surfaces, Sean A. Broughton
Quasi-Platonic Psl2(Q)-Actions On Closed Riemann Surfaces, Sean A. Broughton
S. Allen Broughton
This paper is the first of two papers whose combined goal is to explore the dessins d'enfant and symmetries of quasi-platonic actions of PSL2(q). A quasi-platonic action of a group G on a closed Riemann S surface is a conformal action for which S/G is a sphere and S->S/G is branched over {0, 1,infinity}. The unit interval in S/G may be lifted to a dessin d'enfant D, an embedded bipartite graph in S. The dessin forms the edges and vertices of a tiling on S by dihedrally symmetric polygons, generalizing the idea of a …

An Intelligent Attitude Determination And Control System Concept For A Cubesat Class Spacecraft, Jeremy Straub
An Intelligent Attitude Determination And Control System Concept For A Cubesat Class Spacecraft, Jeremy Straub
Jeremy Straub
An attitude determination and control system (ADCS) is used to orient a spacecraft for a wide variety of purposes (e.g., to keep a camera facing Earth or orient the spacecraft for propulsion system use). The proposed intelligent ADCS has several key features: first, it can be used in multiple modes, spanning from passive stabilization of two axes and unconstrained spin on a third to three-axis full active stabilization. It also includes electromagnetic components to ‘dump’ spin from the reaction wheels. Second, the ADCS utilizes an incorporated autonomous control algorithm to characterize the effect of actuation of the system components and, …

Cover Crop Biomass Production And Water Use In The Central Great Plains, David C. Nielsen, Drew J. Lyon, Gary W. Hergert, Robert K. Higgins, Johnathon D. Holman
David C. Nielsen
The water-limited environment of the semiarid Central Great Plains may not produce enough cover crop biomass to generate benefits associated with cover crop use in more humid regions. There have been reports that cover crops grown in mixtures produce more biomass with greater water use efficiency than single-species plantings. This study was conducted to determine differences in cover crop biomass production, water use efficiency, and residue cover between a mixture and single-species plantings. The study was conducted at Akron, CO, and Sidney, NE, during the 2012 and 2013 growing seasons under both rainfed and irrigated conditions. Water use, biomass, and …

Software Design For An Intelligent Attitude Determination And Control System, Matthew Russell, Jeremy Straub
Jeremy Straub
Space exploration and satellite missions often carry equipment that must be accurately pointed towards distant targets, therefore making an effective attitude determination and control system (ADCS) a vital component of almost every spacecraft. However, the effectiveness of the ADCS could decrease drastically if components shift during launch, degrade in efficiency over the course of the mission, or simply fail. Prior work [0] has presented a concept for a adaptive ADCS which can respond to changing spacecraft conditions and environmental factors. This poster presents an implementation for a lazy learning ADCS is presented that uses past maneuver data to construct and …
Testing A Novel Cryptosystem For Use In Securing Small Satellite Communications, Samuel Jackson, Scott Kerlin, Jeremy Straub
Testing A Novel Cryptosystem For Use In Securing Small Satellite Communications, Samuel Jackson, Scott Kerlin, Jeremy Straub
Jeremy Straub
Cryptography in the domain of Small Satellites is a topic of growing importance. While large satellites are likely to have the hardware requirements to run common cryptographic algorithms, small satellites are extremely limited in both hardware capabilities, which limits the speed and security of cryptosystems implemented in software, and available physical space, which limits the ability to include cryptosystems implemented in hardware. However, small satellites are growing in popularity, and as such securing communications becomes a necessity for some. The Department of Defense is exploring the possibility of using CubeSats, a type of small satellite, in their operations, as are …
Improving Satellite Security Through Incremental Anomaly Detection On Large, Static Datasets, Connor Hamlet, Matthew Russell, Jeremy Straub, Scott Kerlin
Improving Satellite Security Through Incremental Anomaly Detection On Large, Static Datasets, Connor Hamlet, Matthew Russell, Jeremy Straub, Scott Kerlin
Jeremy Straub
Anomaly detection is a widely used technique to detect system intrusions. Anomaly detection in Intrusion Detection and Prevent Systems (IDPS) works by establishing a baseline of normal behavior and classifying points that are at a farther distance away as outliers. The result is an “anomaly score”, or how much a point is an outlier. Recent work has been performed which has examined use of anomaly detection in data streams [1]. We propose a new incremental anomaly detection algorithm which is up to 57,000x faster than the non-incremental version while slightly sacrificing the accuracy of results. We conclude that our method …

Rooted In Hell: Simulating Phragmites Australis, Rachel Nydegger Rozum, Jacob Duncan, James Powell Ph.D.
Rachel Nydegger Rozum
Across the estuaries of the east coast and wetlands of the Great Lakes, the invasive grass Phragmites australis outcompetes other vegetation and destroys local ecosystems. Because its roots are tolerant to salinity that other plants find hellish, Phragmites invasions begin with vegetative spread of genetic clones in brackish marshlands.This plant can grow over three meters tall at densities of 50 stems/m2, provides poor wildlife habitat, and is very difficult to eradicate. A discrete life stage model on a yearly time step captures seed survivorship in a seed bank, sexual and asexual recruitment into a juvenile age class, and differential competition …

The chapter presents a comparison of results of modelling concentrations of fine dust (suspended dust PM10) in the air with the use of two diffusion models: the Gaussian plume model (used commonly in Poland), and the Gaussian puff model CALPUFF (used significantly less frequently). It indicates discrepancies in obtained results of calculations for point emitters taking into consideration three dimensional options (with the following heights: 20, 40 and 60 m and diameters of respectively: 1.0, 1.5 and 2.0 m). For particular variants, errors were visualised, resulting from use of the simple Gaussian plume model in place of the advanced CALPUFF …

Summary: Deconvolution microscopy has historically been painfully slow. The early vendors were:
- Scanalytics (Carrington and Fay), commercialized to try to sell expensive, specialized array processors made by CSPI (the CSPI box likely had less computing power than a first gen smartphone).
- Applied Precision (Sedat …
