Volume Charging Revisited

We consider fair sharing of network resources over a period of time between offline and interactive users. The former value total transferred volume while the latter have timedependent valuations for instantaneous bandwidth. Following the work of Kelly on fair bandwidth sharing, we express the system optimum as an equilibrium of traditional congestion control taking place in a fast timescale an...

Prediction of circulatory equilibrium in response to changes in stressed blood volume.

Accurate prediction of cardiac output (CO), left atrial pressure (PLA), and right atrial pressure (PRA) is a prerequisite for management of patients with compromised hemodynamics. In our previous study (Uemura et al. Am J Physiol Heart Circ Physiol 286: H2376-H2385, 2004), we demonstrated a circulatory equilibrium framework, which permits the prediction of CO, PLA, and PRA once the venous retur...

Model-based computation of total stressed blood volume from a preload reduction manoeuvre.

Total stressed blood volume is an important parameter for both doctors and engineers. From a medical point of view, it has been associated with the success or failure of fluid therapy, a primary treatment to manage acute circulatory failure. From an engineering point of view, it dictates the cardiovascular system's behavior in changing physiological situations. Current methods to determine this...

Partial Volume Estimation in Brain MRI Revisited

We propose a fast algorithm to estimate brain tissue concentrations from conventional T1-weighted images based on a Bayesian maximum a posteriori formulation that extends the "mixel" model developed in the 90's. A key observation is the necessity to incorporate additional prior constraints to the "mixel" model for the estimation of plausible concentration maps. Experiments on the ADNI standardi...

Pulmonary Blood Volume and Pulmonary Capillary Blood Volume in Valvular

Measurements of pulmonary blood volume (PBV) and pulmonary capillary blood volume (V,) and hemodynamic studies were made in a series of 106 patients with valvular heart disease (62 with predominant mitral lesions and 44 with predominant aortic lesions). The results were compared with the data obtained from 14 "normal" patients and nine normal subjects. In 14 "normal" patients, the PBV varied fr...
