Background
Chronic Chagas cardiomyopathy (CCM) is characterized by a unique type of cardiac involvement. Few studies have characterized echocardiographic (Echo) transitions from the indeterminate Chagas disease (ChD) form to CCM. The objective of this study was to identify the best cutoffs in multiple Echo parameters, speckle tracking, and N‐terminal pro B‐type natriuretic peptide (NT‐proBNP) to...
Splits and joins are one of the major issues that Petri nets have since they can simulate a great variety of industrial processes. This paper introduces a new Petri net called LDPN (Ladder Diagram Petri Net). The new LDPN combines the graphical representation used in classical Petri nets with a new equation derived from standardized ladder circuits. In addition, the new net can easily translate Petri...
In this paper, authors compare the mayor procedures to accomplish a circuit Tor linear process automation, then, they standardize a rung in order to be implemented in a PLC or wired logical. At the end of this paper, authors present a new equation to implement a linear automation process, the equation is derived from a standardized procedure that it has been used for more than 10 years at the control...
Single-walled carbon nanotube-silica nanohybrid particles are a very promising material that could be used for enhanced oil recovery because of their interfacial activity. To demonstrate the basic principle, aqueous nanohybrid particle dispersions were evaluated by looking at the effect of pH, surfactant, and polymer. The results showed that pH did not have significant effect on the dispersion stability...
A new alien wavelength architecture used in long-haul IP over WDM networks is compared against traditional transponder-based WDM. Operational impact and network economics are provided, showing minimal network benefit.
Optimization of IP and WDM network architecture using IP router link bypass provides cost savings in both layers. Results indicate that optimal level of router bypass varies with total traffic volume and router interface speed.
