Compact Gas Sensor Using Silicon-On-Insulator Loop-Terminated Mach–Zehnder Interferometer, Raghi S. El Shamy, Mohamed A. Swillam, Mohamed M. Elrayany, Alaa Sultan

Faculty Journal Articles

In this paper, we propose a compact optical gas sensor based on the widespread silicon-on-insulator (SOI) technology, operating in the near-infrared (NIR) region around the 1.55 µm wavelength. The sensor employs a loop-terminated Mach–Zehnder interferometer (LT-MZI) with a slot waveguide and a strip waveguide for the sensing arm and the reference arm, respectively. For the same arm length, the LT-MZI can achieve a detection limit two times lower than that of the conventional MZI. Different sensor components were designed, and the optimum dimensions were obtained using finite-difference eigenmode (FDE) and finite-difference time-domain (FDTD) solvers. With a sensing arm length of …

The Circle Of Life: The Mathematics Of Predator-Prey Dynamics, John Butler, Rebecca Brady

Articles

Some animals hunt other animals to feed themselves; these animals are called predators. Animals who are hunted and eaten are known as prey. What do you think would happen if a predator were introduced to an ecosystem where the prey previously lived without fear of being hunted? Would the new predator eat all the prey animals until they go extinct? Actually, the relationship between predator and prey is far more interesting than this. In this article, we show what the predator-prey relationship looks like over time and explain how scientists can make predictions about future population levels, all using basic …

Mind The Gap: A Comparative Approach For Fixing Volcker, Learning From Liikanen, And Using Vickers To Repair The U.S. Banking System, Rachel Sereix

Duke Journal of Constitutional Law & Public Policy Sidebar

After the 2008 financial crisis, Congress, courts, and international banking agencies alike determined that their current banking infrastructures were inadequate to prevent such crises in the future. The Dodd-Frank Wall Street Reform Acttried to solve the problem by reducing derivatives-related risk through legislative provisions that increased capital and liquidity requirements for all banks. Yet, banks continued to find means to subvert the system and Congress remained relatively silent on the issue after the passage of Dodd-Frank—failing to amend Dodd-Frank in any meaningful way. Looking towards European peers for guidance about how to reform the United States’ banking regime has often …

Machine Learning Based Critical Resource Allocation In Mixed-Traffic Cellular Networks, Mohamed Nomeir

Theses and Dissertations

The proliferation of cellular networks over the past two decades has encouraged the expansion of their use in many modern applications. These applications involve the use of data traffic of different quality of service (QoS) requirements. Some of these requirements are quite stringent such as in the case of critical Internet of Things (IoT) health care, military and homeland security applications. This situation resulted in imposing a variety of resource allocation requirements on the cellular network operation in a simultaneous manner.

In this thesis, we consider the challenging problem of mixed-traffic resource allocation, or scheduling, in cellular networks. We focus …

Articles

Since it is now possible to make, in a controlled fashion, an almost unlimited variety of nanostructure shapes, it is of increasing interest to understand the forms of biological control that nanoscale shape allows. However, a priori rational investigation of such a vast universe of shapes appears to present intractable fundamental and practical challenges. This has limited the useful systematic investigation of their biological interactions and the development of innovative nanoscale shape-dependent therapies. Here, we introduce a concept of biologically relevant inductive nanoscale shape discovery and evaluation that is ideally suited to, and will ultimately become, a vehicle for machine …

Asymptomatic And Pre-Symptoms Transmission Of Covid-19 In Heterogeneous Epidemic Network, H. A. A. El-Saka, Ayman Al-Dmour, Ibrahim Obaya

Information Sciences Letters

The diversity of the spread pattern of the Corona virus is one of the most important reasons for the seriousness of the virus. Therefore, in this paper, we present a fractional mathematical SEIAS model that studies many ways of spreading (asymptomatic and pre-symptoms transmission) with the hypothesis of the spread of the virus in a heterogeneous network of individuals. The system consists of nonlinear equations which formed in fractional order. And it turns out that the system has two equilibrium positions (free and endemic positions). We also calculated the disease prevalence threshold (R) within the network. The condition for the …

On Generalize L-Moments Method And Application On Control Chart For Monitoring Fractional, Rates And Proportions Data, Enayat M. Abd Elrazik, Mahmoud M. Mansour

Information Sciences Letters

This paper proposes GL-moments’ method as a generalization to the TL-moments and the L-moments methods. Population GL-moments in terms of the quantile function and shifted Jacobi polynomials were defined. Some relations between GL-moments depending on Jacobi Polynomials were also derived. Furthermore, interpretation of the first two population GL-moments by U-statistics was introduced. Also, we obtained two expressions to estimate the population GL-moments: the first expression, which depends on Downton’s estimator, is a nearly unbiased estimator. Finally, to avoid an upper control limit exceeding one in p-chart, we propose a control chart based on generalized linear moments for monitoring fractional, rates …
