An Empirical Study on Flow-based Botnet Attacks Prediction

October 22, 2020
Author(s)
Mitsuhiro Hatada, Matthew A. Scholl
In the era of the Internet of Things, botnet threats are rising, which has prompted many studies on botnet detection and measurement. In contrast, this study aims to predict botnet attacks, such as massive spam emails and distributed denial-of-service

Application of ASCE 41 to a two-story CFS building

October 22, 2020
Author(s)
Matthew Speicher, Zhidong Zhang, Benjamin W. Schafer
The objective of this paper is to summarize the evaluation results from applying the updated performance-based seismic design provisions: ASCE 41-17, on a cold-formed steel framed building sited in a location with high seismic demands. The assessment

Dual Josephson impedance bridge: towards a universal bridge for impedance metrology

October 22, 2020
Author(s)
Frederic Overney, Nathan Flowers-Jacobs, Blaise Jeanneret, Alain Rufenacht, Anna Fox, Paul Dresselhaus, Samuel Benz
This paper presents a full characterization of a Dual Josephson Impedance Bridge (DJIB) at frequencies up to 80 kHz by using the DJIB to compare the best available impedance standards that are (a) directly traceable to the quantum Hall effect, (b) used as

FPGA-based Low-Latency Digital Servo for Optical Physics Experiments

October 22, 2020
Author(s)
Marco Pomponio, Archita Hati, Craig Nelson
We propose a general-purpose dual-channel field-programmable gate array (FPGA) based digital servo with a minimum latency around 200 ns. This servo implements a proportional, dual- integration and derivative (PIID) controller along with internal numerical

PSCR 2020_ Prototyping 3D User Interfaces for First Responders

October 22, 2020
Author(s)
Katelynn A. Kapalo
Due to rapid advances in technology, first responders will eventually have access to building information, sensor data, and fire protection system data in real time. However, the presentation of this critical information has not been fully evaluated from

The New NIST Phish Scale, Revealing Why End Users Click

October 22, 2020
Author(s)
Shanee T. Dawkins, Kristen Greene, Jody L. Jacobs
Developed based on over 4 years of NIST phishing training data, the NIST Phish Scale is a DIY method for rating human phishing detection difficulty – key to understanding variability in phishing click rates. This talk will cover why users click, why it’s
