Calculating Cardiovascular Lumped-Parameter Model Values by Injecting Small Volume Perturbations in an Isovolumic Heart
(North Dakota State University, 2011)Diagnosing cardiac patient problems contains many uncertainties, and to fully diagnose the patient's condition usually requires a lengthy drug regimen to see what works and what does not. Compounding this problem is that ... -
The Capacity Region of the Gaussian Z-Interference Channel with Gaussian Input and Weak Interference
(North Dakota State University, 2016)We consider a wireless communication scenario with two transmit-receive pairs where each of the transmitters has a message for its corresponding receiver and only one of the receivers face interference from the undesired ... -
Capacity Region of Two Interfering Mimo Multiple Access Channels With Strong Interference
(North Dakota State University, 2015)We consider a communication network, where two mutually interfering 2-user MIMO Multiple Access Channels (MAC) operate simultaneously via the same time-frequency space, and characterize the capacity region of this network ... -
The Capillary-Centric Model of Coupling-As-Thermodynamics
(North Dakota State University, 2015)Models of ventricular-arterial coupling (VAC) have historically described the heart as a function of its energetic interaction with the arterial system. However, these models either represent the dynamic, adaptive ... -
