Fuzzy regression (FR) been demonstrated as a promising technique for modeling manufacturing processes where availability of data is limited. FR can only yield linear type FR models which have a higher degree of fuzziness, but FR ignores higher order or interaction terms and the influence of outliers, all of which usually exist in the manufacturing process data. Genetic programming (GP), on the ...
Flood susceptibility mapping using frequency ratio and weight of evidence technique: a case study of Kermanshah Province abstract Flood is considered as one of the most destructive natural disasters worldwide, because of claiming a large number of lives and incurring extensive damage to the property, disrupting social fabric, paralyzing transportation systems, and threatening natural ecosy...
Let F1, . . . ,Fr ⊂ ([n] k ) be r-cross t-intersecting, that is, |F1 ∩ ·· · ∩Fr| ≥ t holds for all F1 ∈ F1, . . . ,Fr ∈ Fr. We prove that for every p,μ ∈ (0,1) there exists r0 such that for all r > r0, all t with 1 ≤ t < (1/p− μ)r−1/(1− p)−1, there exist n0 and ε so that if n > n0 and |k/n− p|< ε , then |F1| · · · |Fr| ≤ (n−t k−t )r .
Of 10 geographic strains of Flammulina velutipes, 4 were found capable of fruiting at 22 degrees C (Fr(H)) rather than at the typical 15 degrees C (Fr(L)). Crosses made between Fr(H) and Fr(L) monokaryons were never observed to fruit at 22 degrees C. However, some hybrids did fruit at the intermediate temperature of 18 degrees C when grown on appropriate substrates, indicating incomplete domina...
Face color information can play an important role in face recognition (FR) and it can be used to considerably improve FR performance obtained using only grayscale images. The color-based FR methods involve a preprocessing step where a color image is converted into either a monochromatic image or an image having a different color representation. In practical FR systems, the recording or transmis...
Food restriction (FR) seems to be the unique experimental manipulation that leads to a remarkable increase in lifespan in rodents. Evidences have suggested that FR can enhance memory in distinct animal models mainly during aging. However, only few studies systemically evaluated the effects FR on memory formation in both adult (3-month-old) and aged (18-24-month-old) mice. Thus, the aim of the p...
Three noncontrast-enhanced MR venography techniques are presented for assessing deep vein thrombosis (DVT) at 0.5 T in patients with metallic implants. Two cardiac-gated 3D half-Fourier FSE fresh blood imaging sequences with flow-refocusing pulses (FR-FBI) in the read-out (RO) direction and without FR pulses (non-FR-FBI) were developed for slower-flowing blood. For faster flowing blood, a swap ...
