Normalized Linearly-Combined Chaotic System: Design, Analysis, Implementation And Application, Md Sakib Hasan, Anurag Dhungel, Partha Sarathi Paul, Maisha Sadia, Md Razuan Hossain

Faculty and Student Publications

This work presents a general framework for developing a multi-parameter 1-D chaotic system for uniform and robust chaotic operation across the parameter space. This is important for diverse practical applications where parameter disturbance may cause degradation or even complete disappearance of chaotic properties. The wide uninterrupted chaotic range and improved chaotic properties are demonstrated with the aid of stability analysis, bifurcation diagram, Lyapunov exponent (LE), Kolmogorov entropy, Shannon entropy, and correlation coefficient. We also demonstrate the proposed system’s amenability to cascading for further performance improvement. We introduce an efficient Field-Programmable Gate Array (FPGA)-based implementation and validate its chaotic properties using …


Biomembrane-Based Memcapacitive Reservoir Computing System For Energy-Efficient Temporal Data Processing, Md Razuan Hossain, Ahmed S. Mohamed, Nicholas X. Armendarez, Joseph S. Najem, Md Sakib Hasan Oct 2023

Biomembrane-Based Memcapacitive Reservoir Computing System For Energy-Efficient Temporal Data Processing, Md Razuan Hossain, Ahmed S. Mohamed, Nicholas X. Armendarez, Joseph S. Najem, Md Sakib Hasan

Faculty and Student Publications

Reservoir computing is a highly efficient machine learning framework for processing temporal data by extracting input features and mapping them into higher dimensional spaces. Physical reservoirs have been realized using spintronic oscillators, atomic switch networks, volatile memristors, etc. However, these devices are intrinsically energy-dissipative due to their resistive nature, increasing their power consumption. Therefore, memcapacitive devices can provide a more energy-efficient approach. Herein, volatile biomembrane-based memcapacitors are leveraged as reservoirs to solve classification tasks and process time series in simulation and experimentally. This system achieves a 99.6% accuracy for spoken-digit classification and a normalized mean square error of 7.81×10−4$7.81 \times …

The Biological Activity Of Dual-Responsive Glycopolymers For Intracellular Codelivery Of Antigen And Lipophilic Adjuvant, Micaela Shields May 2023

The Biological Activity Of Dual-Responsive Glycopolymers For Intracellular Codelivery Of Antigen And Lipophilic Adjuvant, Micaela Shields

Honors Theses

Subunit vaccines present themselves as an attractive alternative to traditional approaches to vaccines, which utilizes whole organisms to trigger an immune response. While these traditional approaches have proven themselves reliable within the history of vaccinations, they generally deliver subpar robust cellular-mediated immunity and pose many safety risks. Composed of proteins and /or peptides, subunit vaccines are safer and more precise alternatives to traditional approaches. However, the pharmacokinetic properties of the macromolecules that make up these vaccines hinder the subunit vaccine’s level of immunogenicity [d1] Examples of this hindrance include but are not limited to aggregation at the injection site and …

The Use Of Scattering Cancellation To Cloak And Decouple Slot Antennas And Antenna Arrays, Daniel Ferro May 2023

The Use Of Scattering Cancellation To Cloak And Decouple Slot Antennas And Antenna Arrays, Daniel Ferro

Honors Theses

The concept of cloaking has been prevalent in emerging research, being able to hide oneself completely from outside observers would be a huge benefit for covert surveillance and other fields. This idea has expanded past optical invisibility into the field of electromagnetic invisibility. To accomplish this form of cloaking, a non-natural material, called metamaterials, must be used. Furthermore, metamaterials can be used in a variety of different techniques including transformation-based cloaking, transmission line cloaking, and scattering cancellation cloaking. One application of cloaking is to use scattering cancellation to decouple two antennas that are placed too closely together such as in …

The Antler: The Design And Development Of An Independent Shower Support Stand For Those Living With Lower Extremity Limb Loss, Kylie Wright

Honors Theses

While we do not often think about it, taking a shower is a privilege. Standing in the hot water, cleaning off after a long day outdoors, and taking a moment to simply relax is an experience that most people in the U.S. have participated in. However, about 1.4 million Americans do not have this luxury3. Lower extremity amputees have long been advised to shower while seated for their safety. This population is unable to experience the simple independence that accompanies standing in the shower. Despite the growing rate of amputations each year, no products are currently available on the market …
