PURPOSE Optical coherence tomography (OCT) allows quantification of the thickness of the retinal nerve fibre layer (RNFL) thickness, a potential biomarker for neurodegeneration. The estimated annual RNFL loss in multiple sclerosis amounts to 2 μm using time domain OCT. The recognition of measurement artifacts exceeding this limit is relevant for the successful use of OCT as a secondary outcome ...
The power domination problem is to find a minimum placement of phase measurement units (PMUs) for observing the whole electric power system represented by a graph G. The number of such a minimum placement of PMUs is called the power domination number of G and is denoted by γp(G). Finding γp(G) of an arbitrary graph is known to be NP-complete. In this paper, we deal with the power domination pro...
a 30-year-old female with end-stage renal disease was a candidate for dual lumen catheter placement. after catheter insertion, o2 saturation measurement of the aspirated blood from the catheter was similar to that of arterial blood. they referred the patient to our hospital after 48 hours. diagnostic procedures revealed that the tip of the catheter had entered the pleural cavity. catheter remov...
Traditional recommendations suggest placement of a subclavian central venous catheter (CVC) ipsilateral to a known pneumothorax to minimize risk of bilateral pneumothorax. We present the case of a 65-year-old male with a right hemopneumothorax who was found to have intrathoracic placement of his right subclavian CVC at thoracotomy despite successful aspiration of blood and transduction of centr...
The analysis of power system observability and the rules of PMU placement are concisely presented. Several algorithms of PMU placement as well as their differences and relations are discussed in details: a graph-theoretic procedure based on Depth First Search can find the optimal placement the most quickly; Simulated Annealing Method can help the algorithm converge to global optimum. Base on th...
We extend an existing virtual reality terrain visualization framework to support spatial analysis tasks for geoscientific purposes. We demonstrate both interactive measurement of height profiles as well as volume measurement within polygonal footprints. In this application, virtual reality technology enables superior perception of the placement of these lines with respect to terrain features.
With the arrival of partial reconfiguration technology, modern FPGAs support tasks that can be loaded in (removed from) the FPGA individually without interrupting other tasks already running on the same FPGA. Many online task placement algorithms designed for such partially reconfigurable systems have been proposed to provide efficient and fast task placement. In these algorithms, the resource ...
