(North Dakota State University, 2016)This thesis presents Algorithmic State Machine (ASM) designs that follow the One Cycle Demand Driven Convention (OCDDC) of three cryptographic protocols: Secure Distributed Multiplication (SDM), Pi Secure Distributed ... -
Effects of Alternating Current Electrical Stimulation on the Cellular Chemistry and Proliferation of C2C12 Muscle Cells
(North Dakota State University, 2016)The objective of this study was to investigate the effects of electrical stimulation on the cellular chemistry and proliferation of C2C12 muscle cell line. The cells were cultured under the condition of AC electrical ... -
A Variable High Gain and High Dynamics Range CMOS Phase Shifter for Phased Array Antenna Applications
(North Dakota State University, 2016)Phase shifters can adjust phases electronically and hence is very popular for phased array antenna applications where radiation angle can be scanned electronically avoiding bulky mechanical rotation arrangement. In this ... -
The Interaction of Radio Frequency and Lambda DNA
(North Dakota State University, 2016)By exposing an aqueous DNA solution to a spectrum of radio frequency (RF) energy this research identifies frequencies, if any, where DNA interacts with RF energy. Interaction is determined by the amount of RF energy either ... -
Equivalent Circuit Modeling and Signal Integrity Analysis of Magneto-Static Responsive Structures, and Their Applications in Changing The Effective Permittivity of Microstrip Transmission Lines
(North Dakota State University, 2016)This work presents the equivalent circuit model, ringing and overshoot characteristics, as well as the ability of a new magneto-static responsive structure (MRS) to achieve the recon gurabil- ity of a variable e ective ... -
Equivalence Verification for NULL Convention Logic and Latency-Insensitive Circuits
(North Dakota State University, 2016)NULL convention logic and latency-insensitive circuits are delay-tolerant circuits that can be synthesized from a synchronous speci cation. These design paradigms can use existing CAD ows to implement circuits that are ... -
The Effects of 2.45 GHZ Radio Frequency Energy on Neurological Tissue Genes Using an Unrestrained Murine Model In Vivo
(North Dakota State University, 2016)The effects that radio frequency (RF) energy has on the body is currently an inconclusive and controversial topic. This is in part due to the differences and issues that can be found in previous studies. This thesis ... -
The Design and Analysis of a Conformal Spiral Antenna Structure for an Ultra-Wide-Band Radar System
(North Dakota State University, 2016)This thesis explores the design, simulation, and analysis of two conformal spiral antenna structures that are used for an ultra-wide-band (UWB) bistatic radar. The radar antenna system operates over a frequency range ... -
The Capacity Region of the Gaussian Z-Interference Channel with Gaussian Input and Weak Interference
(North Dakota State University, 2016)We consider a wireless communication scenario with two transmit-receive pairs where each of the transmitters has a message for its corresponding receiver and only one of the receivers face interference from the undesired ... -
Personalized Health Insurance Services Using Big Data
(North Dakota State University, 2016)Cloud computing paradigm has significantly affected the healthcare sector like various other business domains. Persistently growing healthcare data over the Internet has called for the development of methodologies to ... -
Analysis of Secrecy in Multi-User Wireless Network
(North Dakota State University, 2018)We consider an Ergodic Fading Broadcast Channel with one Legitimate receiver and one Eavesdropper (BCoLoE) having arbitrary fading statistics, where the instantaneous Channel State Information (CSI) are known only at the ... -
Characterization of a Structure Consisting of Magnetostatic Responsive Microscopic Particles and Its Applications In Antennas
(North Dakota State University, 2015)Wireless communication systems often require that a single antenna work at different frequencies. Thus the recon gurable antennas are useful in frequency agile environments to receive a signal over multiple bands. Research ... -
Energy Efficient Resource Scheduling Methodologies for Cluster and Cloud Computing
(North Dakota State University, 2015)One of the major challenges in the High Performance Computing (HPC) clusters, Data Centers, and Cloud Computing paradigms is intelligent power management to improve energy efficiency. The key contribution of the presented ... -
Individualized Cardiac Resynchronization Therapy: Next Generation Pacemaker Controls
(North Dakota State University, 2015)Cardiac dyssynchrony (CD) causes some heart muscle regions to contract at different times, and current treatments do not help 30 – 50% of patients. In this thesis, multi-site pacing control schemes are created to quantitatively ... -
A Far-Field Radio Frequency Experimental Exposure System and 31 Day Exposure Experiment on Understanding Mice
(North Dakota State University, 2015)Many studies have been performed on exploring the effects of radio frequency energy on biological function in vivo. In particular, gene expression results have been inconclusive due, in part, to a lack of a standardized ... -
