To provide optimal cut-off values of anti-Middle East respiratory syndrome coronavirus (MERS-CoV) serologic tests, we evaluated performance ELISA IgG, IgA, IFA IgM, and IgG using 138 serum samples 49 MERS-CoV-infected patients 219 rRT-PCR-negative MERS-CoV-exposed healthcare personnel patients. The analysis was conducted for two different purposes: (1) prediction neutralization activity in patients, (2) epidemiologic surveillance MERS-CoV infections among individuals. evaluate according to...
Reliability of the electrical power system is a critical factor for continuous process operations. This paper presents an analytical method determining distribution reliability that can be easily implemented to form basis plant improvement studies. The demonstrates implementation failure modes and effects analysis fault tree techniques based on IEEE gold book. provides informed decisions when selecting systems designed increase availability. are illustrated using two simple schemes it shown...
The capabilities and advantages of vacuum interrupters (VIs) have been widely recognized on switching controlling the fault currents in medium voltage level, there doing various research developments for using VIs transmission distribution lines due to its environmental friendliness nowadays. An axial magnetic field (AMF) electrode has more capability than other contact designs such as reducing arc voltage, securing higher current value transferring from constriction diffuse regulating...
An air amplifier makes flow increased by ejecting a small amount of air, which results in the Coanda effect: A tendency keeping fluids attached to an adjacent surface while is passing along wall boundary. In this paper, characteristics were investigated with various and geometrical conditions. particular, values nozzle clearance (δ = 0.1, 0.2, 0.3, 0.4, 0.5 mm), diffuser angles (α 15°, 20°, 25°), pressure conditions (pc 0.4 MPa) considered. Numerical analysis was performed using commercial...
The flow behavior of polymers was analyzed using a commercial finite element software, DEFORM-2D, for the replication microstructures. An alignment structure microassembly, hemisphere-tipped post, modeled to demonstrate polymer in hot embossing. mold filling with evaluated by heights molded posts. results simulation showed better fidelity post increase molding temperature and displacement insert. complete cavity achieved at temperatures 112.5, 125, 137.5, 150°C when displacements were 1.5,...
While it is difficult to detect target signals, online monitoring remains the most reliable method for protection of underground pipelines from third party damage. In this paper, an acoustic wave propagation model based on data communication by local area network generated along gas any damage and its location pipelines. modelling propagation, auto power spectral density cross processing methods are applied distinguish signals noises number sensors in accordance with attenuation coefficient.
In order to get higher throughput efficiency in read/write operations on high density optical disks, a new disk system using near field (NF) probe arrays and VCSEL has been designed. Near optics with evanescent waves, from which the power decreases exponentially distance, are adopted this arrays, microlens near-field tip arrays. The most important technology be developed is self-alignment technique between focal point of numerical aperture (NA) tip. System design details preliminary...
