Ad-hoc on-demand routing protocols like ZRP establish and maintain routes on-demand. However, the paths established by on-demand protocols, which are optimal during route establishment phase, become sub-optimal over time due to node mobility. In this paper, we propose a Path Establishment Algorithm (PEA) that optimizes the established routes when feasible without incurring extra overhead. By ut...

electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...

results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...

Koopman spectral analysis has attracted attention for understanding nonlinear dynamical systems by which we can analyze dynamics with a linear regime lifting observations using function. For analysis, need to find an appropriate lift Although several methods have been proposed estimating function based on neural networks, the existing train networks without analysis. In this paper, propose dyna...

We present an admission control framework and loss management techniques in support of a guaranteed statistical service. The service is characterized by (i) the loss rate of application data units (ADUs) bounded below a specified value, and (ii) ADU losses distributed evenly among flows subscribing to the service and uniformly over the duration of each flow. Specifically, a flow is modeled as a...
