Batch size optimization based on production part cost

When investigating different location and/or system designs the possible variables to take into consideration can differs between the alternatives. Different production system will have different optimal working conditions and hence should be compared with parameters suitable for the actual production system. When planning production and calculating production costs the batch size is of high inter

Investigation of the np ^(2)P_(3/2) Level Sequence in the Cs I Spectrum by Level Crossing Spectroscopy

Our previous level crossing measurements in the 6, 7, and 8 p 2 P 3/2 levels of Cs 133 have been extended to the 9 and 10 p 2 P 3/2 levels. For the magnetic dipole and the electric quadrupole interaction constants a and b we obtain ##IMG## [http://ej.iop.org/images/1402-4896/5/4-5/010/img1.gif] {figure 1} The natural lifetime of 9 p 2 P 3/2 was found to be 390 (30) ns. The previous analysis for th

Modes of propagation of electromagnetic pulses in open dispersive slab waveguides

As a preparatory study of electromagnetic pulse propagation in open waveguides, the modes of propagation of pulses in open slab waveguides are investigated systematically. Core and cladding both consist of simple (linear, homogeneous, isotropic), dispersive materials modeled by temporal convolution with physically sound susceptibility kernels. Under these circumstances, pulses cannot propagate alo

An RFID implementation in the automotive industry - improving inventory accuracy

This paper explores and describes the impact of radio frequency identification (RFID) technology on inventory accuracy within a production and assembly plant, and proposes a model for assessing the impact of the technology on inventory accuracy. The empirical investigation, based on case study research, focuses on a RFID implementation at a supplier of bumper and spoiler systems to the automotive

Celecoxib-induced growth inhibition in SW480 colon cancer cells is associated with activation of protein kinase G

Although it is often assumed that the antitumor effects of nonsteroidal anti-inflammatory drugs (NSAIDs) are due to inhibition of cyclooxgenase (COX) activity, specifically COX-2, there is accumulating evidence that COX-2 independent mechanisms can also play an important role. Studies with sulindac sulfone (Aptosyn) and related derivatives have revealed a novel pathway of tumor growth inhibition a
