This article proposes an algorithm for deploying manpower to a statistical process control (SPC) system that monitors a multistage manufacturing system. The algorithm minimizes the expected total cost by optimizing the amount of allocated manpower in the SPC system (referred to as an M-SPC system), as well as the sample sizes, sampling intervals and control limits of the control charts. It also...

In this work we address the integration of Engineering Process Control (EPC) and Statistical Process Control (SPC) in complex multivariate scenarios with dynamics (autocorrelation). There are essentially two different integrative approaches: one in which an SPC supervision mechanism is used, without interfering, with an EPC controller active continuously all the time, and another in which the S...

4 Yeast Division of the Centraalbureau voor Schimmelcultures, Julianalaan 67, 2628 BC Delft, The Netherlands The septal pore cap (SPC) of Trichosporon sporotrichoides CBS 8245 is vesiculartubular, connected with flat-tubular endoplasmic reticulum (ER), and stains densely with zinc/iodine/osmium tetroxide, as does the ER. The SPC of Schizophy//um commune CBS 340.81 is more complex, about 600 nm ...

a simple and efficient procedure has been developed for the synthesis of 2,3-dihydroquinazolin-4(1h)-ones derivatives under solvent-free conditions. this method uses the condensation of isatoic anhydride, aldehydes, and amines in the presence of a catalytic amount sulfonated porous carbon (spc). one of the important advantages of the new method is that the spc could be recycled and reused.

• Density and viscosity behavior of CO 2 + pentane or hexane is determined. Measurements were carried out up to 100 MPa temperatures (293.15 393.15) K. The data good correlated using Tammann-Tait VFT models for densities viscosities, respectively. GERG 2008, PC-SAFT CP-PC-SAFT are examined modelling densities. Viscosities compared with REFPROP10 MYS predictions. This work reports new experiment...

The subtilisin-like proprotein convertases (SPCs) are a family of serine proteinases that process secreted proteins at single or paired basic residues. Each SPC has been localized in the rat anterior pituitary, implying their importance in precursor processing in this tissue. The cellular distribution of each SPC has not been established in each hormone-producing cell type. We used double label...

The vapor-liquid equilibrium of binary mixtures of xenon + SF6 has been measured at nine temperatures from 235.34 to 295.79 K and pressures up to 6.5 MPa. The mixture critical line is found to be continuous between the critical points of the pure components, and hence, the system can be classified as type I phase behavior in the scheme of van Konynenburg and Scott. The excess Gibbs free energie...

Ultrasound imaging systems (UIS) are essential tools in nondestructive testing (NDT). In general, the quality of images depends on two factors: system hardware features and image reconstruction algorithms. This paper presents a new image reconstruction algorithm for ultrasonic NDT. The algorithm reconstructs images from A-scan signals acquired by an ultrasonic imaging system with a monostatic t...
