Joost F. Swennenhuis,Leon Terstappenil berechnet. Zu diesem Zweck werden die Navier-Stokes Gleichungen mit Hilfe einer Finiten Differenzen Approximation numerisch gelöst. Ein hochauflösendes Upwind Schema [HA 84] ermöglicht eine sehr genaue Wiedergabe der bei Untersuchungen im Windkanal erhaltenen Ergebnisse. Die zeitliche Integration

Some Applications of Fibonacci and Lucas Numbers,th these numbers, we generalized Fibonacci and Lucas numbers by using an arbitrary binary relation over the real fields instead of addition of the real numbers and we give properties of the new obtained sequences. Moreover, by using some relations between Fibonacci and Lucas numbers, we provide a me

,Using Artificial Intelligence to Reduce the Risk of Transfusion Hemolytic Reactions,significance of red blood cell antibodies in transfusion candidates with intent to determine whether the patient needs to receive the expensive, rare, antigen-negative blood to avoid an acute hemolytic transfusion reaction that could lead to death. The assay requires a highly trained technician to s

A Compact Ultra-Wideband (UWB) Antenna with Dual Band-Notched Characteristic Based on Small-Size Electromagnetic Bandgap (EBG) Structuretic is presented. Voltage standing wave ratio (VSWR) < 2 is obtained from 2.6 to 12 GHz except over two notched bands from 3.5 to 4.5 GHz, WiMAX/C-band satellite communication, and 5.0–5.5 GHz, WLAN applications. By introducing a small-size four-corner symmetry plane (FCSP) and square patch with sin

Measurement of O2 Uptake and Evolution in Leaves In Vivo Using Stable Isotopes and Membrane Inlet Mass Spectrometry,s .O. and .O., with a semi-permeable membrane gas inlet and isotope mass separation and detection by mass spectrometry. Measurement of evolution and uptake, as well as CO. uptake, at a range of light levels allows composition of a light response curve, here described for French bean (.) and maize (.) leaf discs.

,Übungsbeispiel Tragflügelumströmung,stem are summarized. A focus, here, is on simulation-free reduction techniques that avoid costly time simulations with the full order model and on parametric approaches that can consider design changes. This also includes geometric modifications that are handled by mesh morphing techniques which are
