High-Power, High-Efficiency, Multi-Functional CMOS Radio Frequency Integrated Circuit for Wireless Communication of Unmanned Aircraft System
(North Dakota State University, 2017)
Recently the Unmanned Aircraft System (UAS) has become very popular due to its current and projected opportunities in diversified applications from surveillance to security to militry. The Federal Aviation Administration ...
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 ...
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 ...
Multisine Excitation Design to Increase the Efficiency of System Identification Signal Generation and Analysis
(North Dakota State University, 2012)
Reducing sample frequencies in measurement systems can save power, but reduction to the point of undersampling results in aliasing and possible signal distortion. Nonlinearities of the system under test can also lead to ...
