and approximating each of the integrals by means of the trapezoidal rule (we write F as an abbreviation of the approximation of f(u)) results in ∮∂Bunt+f(u)nxds≈−12(xj+1−xj)(Uj+1n+Ujn)+12(tn+1−tn)(Fj+1n+1+Fj+1n)+12(xj+1−xj)(Uj+1n+1+Ujn+1)−12(tn+1...
the volume is stored in a single 3D array. Depending on the kind of proxy geometry used, either a single 3D texture object or one to three sets of 2D texture slices are
Euler equations are solved by means of three efficient and robust finite volume schemes, namely, central scheme of Jameson-Schmidt-Turkel (JST) and upwind schemes of Roe's Approximate Riemann Solver and Convective Upwind Split Pressure (... M Uygun,K Kirkköprü 被引量: 62发表: 2005年 On...
Optical coherence tomography is a good method to determine the volume of fresh and dried bloodstains in laboratory conditions and allows accurate determination of the dry/fresh ratio. 展开 关键词: forensic science bloodstain pattern analysis blood drop volume optical coherence tomography dry/fresh ...
as the price action rises substantially from 1987.06 to 2098.88. On the ninth of the month, there is a move to the upside of 111.82 points. This positive value means there is enough market support to continue to drive price activity in the direction of the current trend. A negative value ...
The results suggest that the most cost-effective means of preventing further declines of threatened species is to increase the amount of large downed logs through restoration and biodiversity-oriented management in the vicinity of existing areas of natural-like forests. 5. Synthesis. Our results ...
Because time scales are involved that do not depend on the concentration of fluorescent molecules, FCS can be used as a “ratiometric” means of measurement, i.e., it can also extract concentration-independent information from a system. Consider now transitions of the form B* ↔ B, between...
aWe are currently experiencing a high volume of manuscripts which are not appearing in the Science Citation Index due to technical problems with our system. Our Datawarehouse are manually validating and exporting files and working to get manuscripts sent out as soon as they can. 我们当前体验不出版...
Consider a set of two-dimensional random variables φd and θd with sample means φd and θd, variances σφ2 and σθ2, respectively, and a correlation coefficient ρ between the two random variables. The probability density function is as follows: 𝑓(𝜑𝑑−𝜑𝑑 𝜎𝜑,𝜃...
