At first a brief overview of the Finite Difference Element Method (FDEM) is given, above all how an explicit estimate of the error is obtained. Then for some academic examples the estimated and exact error are compared showing the quality of the estimate. The PDEs for fuel cells of PEMFC and SOFC type with extremely nonlinear coefficients are solved and the error estimate shows the quality of t...

Introduction: Medication errors are among the most serious health errors threatening patient safety in all countries, with major impacts on public health. Midwives as members of healthcare systems are prone to such errors. Therefore, in this study, we aimed to determine medication errors and the contributing factors among midwives working in maternity units of Mashhad University of Medical Scie...

Exploiting dynamic scaling and homogeneity in the bi-limit, we developp a new class of high gain observers which incorporate a gain update law and nonlinear output error injection terms. A broader class of systems can be addressed and the observer gain is better fitted to the incremental rate of the nonlinearities. The expected improved performance is illustrated.

We report the occurrence of triploid preimplantation embryos following in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in a woman with two previously-identified triploid conceptuses which spontaneously underwent fetal demise at 10 and 23 weeks' gestation. An error in maternal meiosis II is proposed as the most likely cause.

background tennis elbow (te) is a common myotendinosis. it was first described by runge in 1873; different modes of treatment are used in management of te. objectives this study aimed to report the results of autologous blood injection (abi) in the treatment of te. materials and methods a prospective case study was performed to evaluate the results of abi in the management of te. the level of p...

We have experimentally demonstrated current-injection optical phase-lock loops (OPLLs) based on commercial single-section semiconductor distributed-feedback (DFB) lasers. Using two parallel OPLLs, we have obtained 87% efficient coherent power combining of the two DFB lasers. The rms differential phase error between the two lasers is about 30 degrees .

Error-free all-optical packet switching is demonstrated by use of a multiwavelength mutual injection-locked Fabry-Perot laser diode. A 10-Gbit/s data signal is switched on and off with an extinction ratio of 16.9 dB when an optical control signal is turned off and on with a power difference of only 3 dB.

This paper presents a fault tolerance architecture for data fusion mechanisms that tolerates sensor faults in multirotor Unmanned Aerial Vehicle (UAV). The developed approach is based on the traditional duplication/comparison method and carried out via error detection system recovery to both detect isolate faulty sensors. It applied an informational framework using extended Informational Kalman...

Gas flooding has proven to be a promising method of enhanced oil recovery (EOR) for mature water-flooding reservoirs. The determination optimal well control parameters is an essential step proper and economic development underground hydrocarbon resources using gas injection. Generally, the optimization in requires use compositional numerical simulation forecasting production dynamics, which com...
