Using GitHub as a Teaching Tool for Programming Courses
GitHub has become the most popular code management platform in the software development industry. It allows developers to manage their software development projects and collaborate with each other. Recently, educators also started using GitHub as a teaching tool for programming courses by hosting code samples and managing student assignments. In this study, we examine how GitHub is being used in academia, and we discuss the motivations and the benefits of using this platform. We also present authors’ experience of using GitHub in programming courses of a software engineering program. We discuss the benefits and challenges of using GitHub and GitHub classroom in the classroom.Cockrell School of Engineerin
A Low-Complexity Graph-Based LMMSE Receiver Designed for Colored Noise Induced by FTN-Signaling
We propose a low complexity graph-based linear minimum mean square error
(LMMSE) equalizer which considers both the intersymbol interference (ISI) and
the effect of non-white noise inherent in Faster-than-Nyquist (FTN) signaling.
In order to incorporate the statistics of noise signal into the factor graph
over which the LMMSE algorithm is implemented, we suggest a method that models
it as an autoregressive (AR) process. Furthermore, we develop a new mechanism
for exchange of information between the proposed equalizer and the channel
decoder through turbo iterations. Based on these improvements, we show that the
proposed low complexity receiver structure performs close to the optimal
decoder operating in ISI-free ideal scenario without FTN signaling through
simulations.Comment: 6 pages, 6 figures, IEEE Wireless Communications and Networking

Steady state entanglement of two atoms created by classical driving field
The stabilization of steady state entanglement caused by action of a
classical driving field in the system of two-level atoms with the dipole
interaction accompanied by spontaneous emission is discussed. An exact solution
shows that the maximum amount of concurrence that can be achieved in Lamb-Dicke
limit is 0.43, which corresponds to the entanglement
ebit. Dependence of entanglement on interatomic distance and classical driving
field is examined numerically.Comment: 14 pages, 2 figure
1-Bromopropane Capture with Hydrophobic Zeolites: Force Field Development and Molecular Simulations
1-Bromopropane is a solvent used in various industrial and commercial applications. United States Environmental Protection Agency recently concluded that 1-bromopropane posed unreasonable risks to human health in several conditions of use. In this work, the adsorption of 1-bromopropane vapors in zeolites was investigated using molecular simulations. First, a united-atom model of 1-bromopropane was developed and the model was validated to reproduce vapor-liquid equilibrium properties of 1-bromopropane by carrying out Gibbs ensemble Monte Carlo simulations. The new model was then used to investigate the capture of 1-bromopropane in hydrophobic zeolites with Monte Carlo simulations in the grand canonical ensemble. The results show that a filtering system that consists of MRE and STW zeolites can capture 1-bromopropane within its ambient concentration range that occurs as a result of 1-bromopropane release in various industrial and commercial applications as identified by the US EPA. While MRE zeolite has the optimal pore size that provides favorable host-guest interactions to capture 1-bromopropane at extremely low concentrations, rapid condensation of 1-bromopropane occurs at relatively higher concentrations in the intersections of narrow helical and straight pores in the STW zeolite
