IFIP — The International Federation for Information Processing > Design Methods and Applications for Distributed Embedded Systems > Networks and Communication > 133-144

The largely synchronous sensor network software architecture (LaSSeNSA) was formulated with the goal of enabling efficient construction of sensor networks that are easily analyzable and can rarely run into a chaotic situation. There are largely three parts in LaSSeNSA; (1) Global time based coordination of uses of shared communication channels; (2) Global time based coordination of group configuration...

Magneto‐convection in a rotating layer of nanofluid

Dhananjay Yadav, R. Bhargava, G. S. Agrawal, Gyeong S. Hwang, more

Asia‐Pacific Journal of Chemical Engineering > 9 > 5 > 663 - 677

The combined effect of rotation and magnetic field on the onset of convection in a horizontal layer of electrically conducting nanofluid is studied. Three cases of free–free, rigid–free, and rigid–rigid boundaries are considered. The two important effects of Brownian motion and thermophoresis are included in the model of nanofluid. The linear stability theory is employed, and the resulting eigenvalue...

Microfluidics and Nanofluidics > 2014 > 17 > 6 > 1085-1093

The effect of rotation on the onset of Soret-driven buoyancy convection in an initially quiescent, horizontal fluid saturated porous layer with nanoparticles suspensions heated from above is analyzed theoretically using linear theory and relative stability concept. In the case of large negative Soret coefficient with high solute Rayleigh–Darcy number, the convective motion sets in during the transient...

A speed sea trial was performed in the Amundsen Sea in February and March of 2012. The Korean ice breaking research vessel “Araon” was used to check speed performance on the big floes. Two of ice trial cases were carried out. We describe the time history of location, the engine power, and the revolutions per minute during the ice trial, and the trajectory of the ship. Additionally, the measured ice...

We report the synthesis and optimization of NASICON-type carbon-coated Li₃V₂(PO₄)₃ by solid-state approach. Adipic acid (AA) is used as the source material for the carbon. Initially, the synthesis of monoclinic Li₃V₂(PO₄)₃ is optimized at a precalcination temperature of 300 °C for 4 h and 900 °C for 8 h under Ar flow to yield a single phase. Powder characterizations such as thermogravimetric–differential...

Coronary Artery Disease in a Large Renal Transplant Population: Implications for Management

M. R. Kahn, A. Fallahi, M. C. Kim, R. Esquitin, more

American Journal of Transplantation > 11 > 12 > 2665 - 2674

Coronary artery disease (CAD) accounts for approximately one‐half of the sizable mortality in patients with end‐stage renal disease who have undergone transplantation. The study was a retrospective review of 1460 patients who underwent renal transplantation at the Mount Sinai Medical Center from January 1, 2000 to October 31, 2009. Noninvasive stress testing was performed in 848 patients (88.1%) with 278 patients (32.8%) having abnormal results. Cardiac catheterization was performed in 357 patients (37.1%) and of these, 212 patients had obstructive disease (59.4%). At 5 years posttransplant, there was no statistically significant difference between those with nonobstructive CAD and those who required percutaneous or surgical interventions (adjusted hazard ratio [aHR], 1.243; CI 95%, 0.513–3.010; p = 0.630). Those with medically managed obstructive CAD had significantly higher rates of death at the 5‐year period when compared to those who received percutaneous intervention (aHR, 3.792; CI 95%, 1.320–10.895; p = 0.013) or those who received coronary artery bypass grafting (aHR, 6.691; CI 95%, 1.200–37.323). Because noninvasive imaging is poorly predictive of coronary disease in this high‐risk population, an anatomic diagnosis is recommended. Revascularization may result in improved long‐term outcomes.

Linear stability analysis on the onset of Soret-driven motion in a nanoparticles suspension

M. C. Kim

The European Physical Journal E > 2011 > 34 > 3 > 1-9

. The onset of Soret-driven instability in binary mixture heated from above is analysed using the linear stability theory. The horizontal fluid layer placed between two plates is in a thermally stable state but the Soret diffusion can induce buoyancy-driven convection in the case of a negative Soret coefficient. It is well known that convective motion sets in from both boundaries if the Rayleigh number...

British Journal of Anaesthesia > 2009 > 103 > 6 > 817-821

Emergence from anaesthesia and tracheal extubation can be associated with hyperdynamic circulatory responses. We examined the effects of maintaining a remifentanil infusion on recovery profiles such as coughing and cardiovascular responses after general anaesthesia. Forty patients undergoing endoscopic sinus surgery under general anaesthesia using total i.v. anaesthesia (propofol and remifentanil)...
