Architecture Design And Optimization Of Edge-Enabled Smart Grids, Adetola B. Adeniran Oct 2020

Architecture Design And Optimization Of Edge-Enabled Smart Grids, Adetola B. Adeniran

USF Tampa Graduate Theses and Dissertations

The emergence of modern monitoring, communication, computation, and controlequipment into power systems has made them evolve into smart grids that can be thought of as the electric grid of things. This evolution has enhanced the efficiency of the power systems through the availability of a large volume of system data that can help with system functions, nevertheless, it has intensified the communication and computation burden on these systems. While many of such computations were traditionally deployed in central servers, new technologies such as edge computing can provide unique opportunities to address some of the computational challenges and improve the responsiveness …


High Performance Distributed On-Chip Voltage Regulation For Modern Integrated Systems, Longfei Wang Nov 2018

High Performance Distributed On-Chip Voltage Regulation For Modern Integrated Systems, Longfei Wang

USF Tampa Graduate Theses and Dissertations

Distributed on-chip voltage regulation where multiple voltage regulators are distributed among different locations of the chip demonstrates advantages as compared to on-chip voltage regulation utilizing a single voltage regulator. Better on-chip voltage noise performance and faster transient response can be realized due to localized voltage regulation. Despite the advantages of distributed on-chip voltage regulation, unbalanced current sharing issue can occur among each voltage regulator, which has been demonstrated to deteriorate power conversion efficiency, stability, and reliability of the power delivery network. An effective balanced current sharing scheme that can be applied to most voltage regulator types is proposed to balance …


Design Issues In Magnetic Field Coupled Array: Clock Structure, Fabrication Defects And Dipolar Coupling, Anita Kumari Jan 2011

Design Issues In Magnetic Field Coupled Array: Clock Structure, Fabrication Defects And Dipolar Coupling, Anita Kumari

USF Tampa Graduate Theses and Dissertations

Even though silicon technology is dominant today, the physics (quantum electron tunneling effect), design (power dissipation, wire delays) and the manufacturing (lithography resolution) limitations of CMOS technology are pushed towards the scaling end. These issues motivated us towards a new paradigm that contributes to a continued advancement in terms of performance, density, and cost. The magnetic field coupled computing (MFC) paradigm, which is one of the regimes where we leverage and utilize the neighbor interaction of the nanomagnets to order the single-domain magnetic cells to perform computational tasks. The most important and attractive features of this technology are: 1) room …
