We review automation requirements and technologies for semiconductor manufacturing. We first discuss equipment integration architectures and control to meet automation requirements for modern fabs. We explain tool architectures and operational issues for modern integrated tools such as cluster tools, which combine several processing modules with wafer-handling robots. We then review recent prog...

Scintigraphic, clinical and pathological findings were correlated in 52 patients studied by technetium-99m stannous pyrophosphate ("mTc-PYP) myocardial scintigraphy before death or surgical resection of myocardium. Fifty-nine clinical events were studied with scintigraphy in the 52 patients; 41 of the 59 were associated with one or more abnormal "mTc-PYP studies and 18 with normal 9OmTc-PYP sci...

Fertility Assimilation of Immigrants: Evidence from Count Data Models This study applies count data estimation techniques to investigate the fertility adjustment of immigrants in the destination country. Data on completed fertility are taken from the 1996 wave of the German Socioeconomic Panel (GSOEP). While the economic literature stresses the role of prices and incomes as determinants of fert...

0 (r sin θ + z)r dz dr dθ (b) Let T be the solid ball of radius 1 centered at (2, 0, 0). Set up, but do not evaluate, a triple integral in spherical coordinates which computes the moment of inertia of T around the z-axis. Hint: First consider the change of variables u = x − 2, v = y, w = z. Solution. After the change of variables, the sphere takes the form u+v+w = 1, and the z-axis becomes the ...

Every year, 536,000 women die from pregnancyrelated causes. More than 80 percent of maternal deaths worldwide are due to five direct causes: hemorrhage, sepsis, unsafe abortion, obstructed labor and hypertensive disease of pregnancy. The latest report from the Confidential Enquiries into Maternal Deaths (UK) lists eclampsia and pre-eclampsia as the second most common cause and showed an increas...
