(2011-08-08)This thesis presents the design of a 20 MHz bandwidth 3rd-order continuous-time low-pass sigma-delta analog-to-digital converter with low-noise and low-power consumption using TSMC 0.18 μm CMOS technology. The bandwidth ...
-
As the power grid becomes more complex and integrated with communication networks, cyber-attacks become an increasingly relevant threat. CYPRES (Cyber Physical Resilient Energy Systems) is a system for simulating cyber and ...
-
(2012-04-19)This paper presents a wireless charging system for portable electric devices. The important impacts of wireless charging systems on the global environment are first examined, and the two basic methods for wireless charging ...
-
One of the most prevalent diseases affecting human communication is hearing loss. About one in every six people has a hearing deficit globally. Many people suffer from hearing loss but cannot afford a hearing aid because ...
-
(2011-08-08)The theory of sensori-computational circuits provides a capable framework for the description and optimization of robotic systems, including on-line optimizations. This theory, however, is inadequate in that it does not ...
-
(2013-02-13)Electromagnetically Functionalized Colloidal Dispersions (EFCDs) have been utilized in several applications in electromagnetics such as reconfigurable antennas. The colloidal dispersions vary the electrical properties ...
-
(2012-05-02)The Global Positioning System (GPS) remains well suited for mobile applications in open areas where the reception of beacon signals from satellites remains in (or near) a line-of- sight path; however, positioning inaccuracies ...
-
(2013-10-07)In this research thesis, we implement Markov Chain Monte Carlo techniques and polynomial-chaos expansion based techniques for states and parameters estimation in hidden Markov models (HMM). Our goal is to estimate the ...
-
Memory prefetching in computer processors is the practice of predicting memory addresses that will need to be accessed and issuing requests to pull data from those addresses ahead of time. These circuits are crucial to ...
-
Cloud compute is an opportunity that has been in the public consciousness for some time now, however more recently we have tried to introduce FPGA’s into cloud-based systems. This offers the advantage of parallelizing a ...
-
(2014-09-08)Due to the nature of hardware and software, their respective design languages have evolved in isolation. Sophisticated languages and design environments exist for both hardware and software; however they remain distinct ...
-
(2013-02-15)As objects continue to be placed into space, Earth orbiting debris are becoming a prominent issue. To counteract this, NASA’s Marshall Space Flight Center’s (MSFC) Engineering Directorate has funded a project to create a ...
-
(2014-10-06)A material’s dielectric properties are determined by its molecular structure, other properties of interest such as the interactions with an applied electromagnetic field can be correlated to the dielectric properties. ...
-
(2021-04-26)The existing electric grid is transitioning to a smart grid with increased penetration of distributed energy resources (DERs), such as photovoltaic (PV) units, battery storage units, electric vehicles (EV), and EV chargers. ...
-
Reliable and efficient communication links are vital in harsh environments where ionizing radiation is present. Optical links specifically are necessary to support the growing need for higher data rates and faster signal ...
-
(2012-04-24)This thesis outlines the design of a real-time digital signal processing technique for pitch detection and analysis via spectral analysis. A sound’s musical pitch can be determined from its fundamental frequency, and a ...
-
Radiologists are in charge of detecting and diagnosing diseases by means of x-rays, Magnetic Resonance Imaging (MRIs), Computed Tomography (CT) scans, and other medical imaging techniques. Of these imaging techniques, chest ...
-
Contactless magnetic gearboxes have been identified by NASA and others to be a potential key enabling technology necessary to realize future fully electric aircraft and spacecraft. These gears are significantly more efficient ...
-
(2013-02-15)Today’s wireless applications have demanded low-power, high-speed, and high-resolution analog-to-digital converters (ADCs) for the reductions in cost, component count, and product size. Continuous-time (CT) Sigma-Delta ...
-
(2013-09-25)Traditional hearing aids do not work well in a noisy environment. In a cocktail party scenario, we receive sound from difference sources. In this case, hearing aids amplify noise and signal at the same time. As a result, ...
