“…For this reason, index was developed to take into account the actual process variation with respect to the target value in the assessment of process performance. Index is proposed by combining indices [7,8,18]. There are several fundamental assumptions that need to be met in order to get reliable decisions about process capability based on these traditional PCIs including normality of the collected data [9], and stability (process-in-control) [9,10,11].…”

Process capability indices are a powerful tool used by quality control engineering to measure the degree to which the process is or is not meeting the requirements. This paper studies the application of process capability indices in the evaluation of a process with asymmetric tolerances. The analyzed collected data of the cleaning liquid “Zahi”, was used to investigate the ability of the filling process to meet the requested specifications. Matlab software was used to plot control charts, normal probability, and histogram of the data gathered from the production line and further performed statistical calculations. It was observed from the control charts that the filling process is under control. In addition, it was revealed by the process capability indices that the process of filling the cleaning liquid bottle is not fitted with the target value but it is adequate.

“…This conrms the corundum structure of a-Fe 2Àx Cu x O 3 (0 # x # 0.17), which is consistent with the values reported in the literature. 14,15 In general, substitutions of larger ions at the Fe sites may lead to an increase in the mean Fe-O bond length, resulting in a shi of the Raman peaks to lower wavenumbers. However, in the present study, it is puzzling that all of the Raman peaks of Cu doped a-Fe 2 O 3 shied slightly to higher wavenumbers, compared to those of undoped a-Fe 2 O 3 .…”

a-Fe 2Àx Cu x O 3 (0 # x # 0.17) nanoparticles were synthesized using an improved homogenous coprecipitation method. The effects of doped Cu on crystal structure of a-Fe 2 O 3 were investigated by field emission transmission electron microscopy, X-ray diffraction and Raman spectroscopy. Owing to the substitution of Cu 2+ at the Fe 3+ sites, the lattice parameters of a-Fe 2Àx Cu x O 3 with an average particle size of $40 nm and a single corundum structure increased with increasing doped Cu concentration. The shifting of Raman peaks for a-Fe 2Àx Cu x O 3 to higher wavenumber was also observed due to the strong electron-phonon interactions and structural distortion after doping Cu. According to the conductivity measurements, doping Cu can increase the concentration of hole carriers and enhance the conductivity of the p-type a-Fe 2 O 3 semiconductor. Furthermore, CH 4 sensing characterization showed that the a-Fe 2Àx Cu x O 3 nanoparticles are sensitive and have a good selectivity to CH 4 at room temperature, and the response of the material is evidently improved by doping with Cu. The maximum response to 2000 ppm CH 4 at room temperature and 50% relative humidity was obtained when x z 0.10, meeting the common requirements in application. These results suggest that a-Fe 2Àx Cu x O 3 nanoparticles can be considered a potential candidate for methane detection at room temperature. ExperimentalAll the chemical reagents were analytically pure without further purication. a-Fe 2Àx Cu x O 3 nanoparticles were prepared by an
