Effect of Caffeine and a Preworkout Supplement on Heart Rate Variability Before and After Exercise
(North Dakota State University, 2016)
Cardiovascular health is negatively affected by overactivity of the sympathetic nervous system (SNS) during rest. Heart rate variability (HRV) has been used to predict SNS activity. The study investigated effects of a ...
The Analysis of Noise Voltage Coupling Between Right-Handed and Meta-Materials Transmission Lines on Printed Circuit Boards
(North Dakota State University, 2013)
An important consideration of RF circuitry in terms of Electromagnetic Compatibility is the correct modeling of the coupling between printed transmission lines. This is very important because the coupled noise voltages ...
Design and Analysis of New Printed Wideband Antennas for Wireless Applications
(North Dakota State University, 2014)
In this study a simple method to develop a wideband antenna is proposed. With this new technique a dipole antenna with a 48% frequency bandwidth is transformed to achieve a 120% frequency bandwidth for a voltage standing-wave ...
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 ...
Viewer-Aware Intelligent Mobile Video System for Prolonged Battery Life
(North Dakota State University, 2017)
In the modern society, mobile is gradually going to become all about video streaming. The main reasons of video growth are mobile devices such as smartphones and tablets which enable people to have access to videos they ...
An Autonomous Reconfigurable Antenna
(North Dakota State University, 2019)
Today’s wireless communications involve more antenna capabilities while occupying the same amount of space. Antennas are able to operate at multiple frequencies [1]-[2], change polarizations [6], have selectable radiation ...
The Context and Concept of Individual and Household Preparedness: The Case of Fako Division in Cameroon
(North Dakota State University, 2015)
Almost every day, we see and hear about disasters impacting individuals and households in communities worldwide. Impacts experienced include loss of life and injury, loss of property, and more. Disasters are often devastating ...
A Conceptual Model of the Individual and Household Recovery Process: Examining Hurricane Sandy
(North Dakota State University, 2014)
This study examined how comprehensively the Bolin and Trainer (1978) model of recovery reflects the recovery process of individuals and households. A review of the literature since 1978 suggested that various revisions and ...
Solution Processing Electronics Using Si6 H12 Inks: Poly-Si TFTs and Co-Si MOS Capacitors
(North Dakota State University, 2011)
The development of new materials and processes for electronic devices has been driven by the integrated circuit (IC) industry since the dawn of the computer era. After several decades of '"Moore's Law"-type innovation, ...
Formal Verification Techniques for Safety Critical Medical Device Software Control
(North Dakota State University, 2016)
Safety-critical medical devices play an important role in improving patients health and
lifestyle. Faulty behaviors of such devices can cause harm or even death. Often these faulty
behaviors are caused due to bugs in ...
