Promising methods to improve the performance of the software-defined networking controller
(Wichita State University, 2019-07)With the continuous development of computer networking, a flexible network architecture will likely have to adapt to the recent growth of Internet-based systems, such as Cloud-based systems, the Internet of Things (IoT), ... -
A promising parallel algorithm to manage the RSA decryption complexity
(IEEE, 2015)In the field of cryptography, public key algorithms are widely known to be slower than symmetric key alternatives for the reason of their basis in modular arithmetic. The modular arithmetic in RSA (short for Ron Rivest, ... -
Propagator method for joint time delay and frequency estimation
(IEEE, 2008-10-26)A novel method of estimating the differential delay of a sinusoidal signal is considered. The new method utilizes the propagator method (PM) which does not require the eigen-decomposition of the cross-spectral matrix (CSM) ... -
Propeller performance measurement for low Reynolds number unmanned aerial vehicle applications
(2005-12)The recent increase in the development of UAV’s and MAV’s has created a strong demand for small propeller performance data. Propeller performance is critical to the success of these aircraft and guaranteed performance ... -
Proportional-Integral-Derivative (PID) controller design for robust stability of arbitrary order plants with time-delay and additive uncertainty
(Wichita State University, 2010-08)In the process control industry, majority of control loops are based on Proportional-Integral-Derivative (PID) controllers. The basic structure of the PID controllers makes it easy to regulate the process output. Design ... -
Proposed method for clean water by addressing nitrogen contrbution to surface water contamination
(Wichita State University, 2018-04-27)Kansas has serious issues as the result of bio-waste generated by livestock feedlots. The Environmental Protection Agency (EPA) has documented the situation as early as 2004. Action on these issues has languished due to a ... -
Protection of occupants in car side impact crashes with an external inflatable upper torso restraint system
(Wichita State University, 2008-12)Passenger vehicles in today’s world are more crashworthy than they used to be. Significant improvements have been done in the recent years to improve protection for occupants in the passenger vehicle; most ... -
Protective bollard design for high speed impact energy absorption
(2006-05)As is passenger safety of paramount importance to the manufacturer of passenger vehicles, so is the security of the nation to its government. Recent developments in the usage of heavy vehicles by militant outfits to carry ... -
Protective shroud for an autonomous unmanned aerial vehicle
(2006-12)Unmanned aerial vehicles are high in demand for various purposes such as surveillance and reconnaissance in military applications. They are also widely used for civilian applications in fire monitoring and analysis, coffee ... -
Protective thermal spray coatings for polymer matrix composites
(2006-12)Polymer matrix composites were coated with metals, alloys and intermetallic compounds using the thermal spray coating technology. Air plasma spraying and flame spraying were the two spraying techniques primarily used ... -
Proton conductivity of graphene-based Nafion® catalyst layer for polymer electrolyte membrane fuel cell
(Wichita State University, 2015-07)Polymer Electrolyte Membrane Fuel Cells (PEMFCs) are the most assuring alternative power sources for a clean energy/environmental future, however, performance needs to be improved for large-scale commercialization. One of ... -
