An evaluation of the effectiveness of smart meter data perturbation mechanisms using a unified stochastic framework
(Wichita State University, 2015-12)The growing energy needs are forcing utility companies towards the use of Advanced Metering Infrastructure (AMI). Smart meters are a part of the AMI, that capture fine grained electric consumption data from households and ... -
Analysis of consensus and collision avoidance using the collision cone approach in the presence of time delays
(Wichita State University, 2016-07)This thesis provides a framework for a combined analysis of consensus algorithms for multi-agent systems that include the presence of obstacles and the presence of communication time delays. The consensus algorithms are ... -
Analysis of elemental concentration and spectral biomarkers in ischemic muscle of patients with peripheral artery disease
(Wichita State University, 2015-07)Peripheral arterial disease (PAD) is a chronic progressive narrowing of the arterial lumen due to atherosclerosis (fat, plaque deposition and hardening of arterial walls), which affects approximately 8 million lives in the ... -
Analysis of MIMO radar impact on MIMO communication system using zero-forcing receiver
(Wichita State University, 2015-12)Spectrum sharing is an approach to solving the congestion problem in radio frequency (RF) bands. The 3500-3650 MHz band has been allocated in the United States for spectrum sharing between military radar systems and cellular ... -
Assessing the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLV): lifting beyond 30 degrees torso asymmetry
(Wichita State University, 2016-07)Dynamic lifting jobs result in a risk of low back disorders (LBDs) higher than any other industrial jobs. There are several ergonomics lifting assessment methods used to evaluate OLBD risk in the lifting jobs. The American ... -
Assisting android application developers with automatic recommendation of permissions
(Wichita State University, 2015-12)The Android platform enjoys the largest market share in mobile applications (84% at the end of 2014). Applications for Android are written mainly in Java and commonly referred to as 'apps'. The explicit permission mechanism ... -
Biocompatibility and biofunctionality evaluations of metallic scaffolds for bone tissue engineering
(Wichita State University, 2015-12)Bone grafting has been widely and successfully used in biomedical fields. Current methods of bone grafting that have been used in medical fields are autografting, allografting, and xenografting but there is a limitation ... -
