Jacobian based power flow model for distribution network
(Wichita State University, 2017-12)With the increase penetration of renewable energy sources (RES) at the distribution level, the possibility of having voltage abnormalities is high. The reason being is because of the intermittent nature of the renewable ... -
Jamming statistics-dependent frequency hopping
(IEEE, 2016)This paper studies a jamming statistics-dependent frequency-hopping (FH) pattern generation scheme. Most existing FH patterns are determined by two encryption keys: (a) one for FH in the frequency domain, and (b) the other ... -
Joining glass fiber layers using a functionalized carbon nanofiber entangled network
(Elsevier, 2012-12-05)As-received glass fiber layers are joined using a carboxylic acid-functionalized carbon nanofiber (OCNF) entangled network utilizing a solution filtering process. Optical and SEM images of the OCNF/glass fiber assembly ... -
Joint physical and link layer error control analysis for nanonetworks in the Terahertz band
(Springer International Publishing AG, 2016-05)Nanonetworks consist of nano-sized communicating devices which are able to perform simple tasks at the nanoscale. The limited capabilities of individual nanomachines and the Terahertz (THz) band channel behavior lead to ... -
A joint power adaptation and spectrum handoff scheme in mobile cognitive radio networks
(IEEE, 2015)Cognitive radio (CR) technology is regarded as a promising solution by enabling unlicensed users to exploit the licensed spectrum unused by the licensed user in an opportunistic manner. Since in a mobile CR network, if ... -
Joint time delay and frequency estimation without eigen-decomposition
(2009-05)In this letter, we addressed the problem of estimating the time delay and the frequencies of noisy sinusoidal signals received at two spatially separated sensors. We employ the Propagator Method (PM) in conjunction with ... -
Jointly optimized QoS-aware virtualization and routing in software defined networks
(Elsevier B.V., 2016-02-26)Software Defined Networks (SDNs) have been recognized as the next-generation networking paradigm that decouples the network control plane from the data forwarding plane. A logically centralized controller is responsible ... -
Kalman filter design for large-scale systems by using unified approach
(Wichita State University, 2013-05)In this thesis, a method of designing a Kalman filter for a linear, discrete-time, singularly perturbed stochastic system using the delta operator was introduced. This unified approach, which is based on the delta operator, ... -
Kalman-Bucy filters with singular correlated noises
(IEEE, 1989-06-21)This paper presents a solution to the singular linear minimum-vaviance estimation problem in the discrete time case. An expression for the transfer function of the Kalman-Bucy filter with nonsingular correlated noises is ... -
Kalman-Filter-Based Adaptive Control: flight testing on general aviation aircraft
(American Institute of Aeronautics and Astronautics, Inc., 2017-09)Sensor noise and turbulence effects have been prevalent issues in control system design. Although a control system may respond well to “clean” input signals and commands in simulation, this may not be the case when a ... -
Kinematic analysis of a motorcycle and rider impact on a concrete barrier under different impact and road conditions
(Wichita State University, 2007-12)In many countries, motorcycle crashes constitutes a significant proportion of all road crash fatalities and injuries and safety measures can be successful only if much more attention is devoted to this issue. Several ... -
Kinematic analysis of a motorcyclist impact on concrete barriers under different road conditions
(AMER SOC MECHANICAL ENGINEERS, 2012)In many countries, motorcycle crashes constitutes a significant proportion of road crash injuries. Several roadside guard systems such as concrete barriers, wire road barriers and steel guard rails are used to protect cars ... -
Kinematic chain based multi-joint capturing using monocular visual-inertial measurements
(IEEE, 2017-09)Combining light-weight visual and inertial modalities for motion capturing has been popular in robotics researches. There exist scale ambiguity, inaccurate pose estimation with little or no baseline, incremental drifts ... -
Kinematics analysis of the chipping process using the circular diamond saw blade
(American Society of Mechanical Engineers (ASME), 1999-05)One of the primary goals in the design of a diamond blade cutting system is to reduce the cutting force. By understanding the fundamentals of the kinematics of the sawing operation, these forces can be lowered and even ... -
Kinetics of prepreg epoxy resin curing for aircraft body repair
(Wichita State University. Graduate School, 2014-04-25)Curing is the cross-linking of polymer chains, which results in toughening of polymer material and it is widely used in bonded composite repair for aerospace components. The main objective of this project is to analyze ... -
Kraus operator formalism for quantum multiplexer operations for arbitrary two-qubit mixed states
(Springer, 2019-12)The dynamics of open quantum systems are described using a set of operators called Kraus operators. In this paper, we show how to find system parameters for a closed system of two qubits undergoing quantum multiplexer ... -
Kraus operator formalism using a reduced Hamiltonian approach on controlled-unitary operations
(Wichita State University, 2017-12)Quantum systems are extremely fragile, and as such, are difficult to isolate from interactions with their environment. Such "open" quantum systems that interact with their environment do not follow the unitary dynamics of ... -
A Kriging Model for dynamics of mechanical systems with revolute joint clearances
(ASME, 2014-07)Over the past two decades, extensive work has been conducted on the dynamic effect of joint clearances in multibody mechanical systems. In contrast, little work has been devoted to optimizing the performance of these ... -
Label-free electrical immunoassay biosensors for early disease diagnosis
(Wichita State University, 2012-05)This thesis focused on developing an inexpensive and user friendly “point- of- care” (POC) device for early disease diagnosis. Proteomics research has elucidated many new proteins as biomarkers that have the potential to ...
