    Description: This open access book assesses the potential of data-driven methods in industrial process monitoring engineering. The process modeling, fault detection, classification, isolation, and reasoning are studied in detail. These methods can be used to improve the safety and reliability of industrial processes. Fault diagnosis, including fault detection and reasoning, has attracted engineers and scientists from various fields such as control, machinery, mathematics, and automation engineering. Combining the diagnosis algorithms and application cases, this book establishes a basic framework for this topic and implements various statistical analysis methods for process monitoring. This book is intended for senior undergraduate and graduate students who are interested in fault diagnosis technology, researchers investigating automation and industrial security, professional practitioners and engineers working on engineering modeling and data processing applications. This is an open access book.

    Notes: The structural and magnetic characteristics of Ho2Co17−xSix (x=0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0) compounds have been investigated by means of x-ray diffraction and magnetic measurements. Powder x-ray diffractograms show that all samples are single phase and have the hexagonal Th2Ni17-type or the rhombohedral Th2Zn17-type structure. The substitution of Si for Co leads to a monotonous decrease in unit cell volume v and Curie temperature TC. The compensation points are observed for the samples with x=2.5 and 3.0, and the compensation temperatures shift to higher temperatures with increasing Si content. The intersublattice-molecular-field coefficient, nHo–Co, has been determined on the basis of magnetization curves at the compensation temperature. It has been found that the Si substitution for Co has little influence on Ho–Co exchange interaction. The magnetic phase diagram has been determined from the temperature dependence of magnetization and the XRD patterns of magnetically oriented powder samples. The spin-reorientation temperatures of Ho2Co17−xSix compounds are found to decrease with Si content for x〈2.5 and then increase for x〉2.5, attaining a minimum value of 237 K at x=2.5. © 2000 American Institute of Physics.

    Notes: X-ray diffraction (XRD) and magnetization measurements were employed to investigate the effect of Mn substitution for Co on the structure and magnetic properties of Y2Co17−xMnx compounds with x=0–8. XRD patterns show that all samples are single phase with a hexagonal Th2Ni17-type structure. The substitution of Mn for Co in Y2Co17−xMnx compounds leads to a monotonic increase in unit cell volume. The saturation magnetization remains nearly constant for x≤3, then decreases quickly with increasing Mn content; this can be explained by the change of the 3d energy band structure and an electron transfer process. The Curie temperature TC is found to decrease rapidly with increasing Mn concentrations. X-ray diffraction measurement on magnetically aligned Y2Co17−xMnx compounds exhibit an easy-plane type of magnetic anisotropy at room temperature for x=0 and an easy-axis type of magnetic anisotropy at room temperature with x=1–7. Substitution of Mn for Co leads to a change of the magnetocrystalline anisotropy of the Co sublattice from the basal plane to the c axis and strongly increases the uniaxial anisotropy of Y2Co17−xMnx. The magnetocrystalline anisotropy field HA is found first to increase and then decrease with increasing Mn concentration, attaining a maximum value of 20.6 kOe at x=3. © 2000 American Institute of Physics.

    Notes: X-ray diffraction (XRD) and magnetization measurements were employed to investigate the effects of Mn substitution for Co on the structure and magnetic properties of Tb2Co17−xMnx compounds with x=0–7. XRD patterns show that all samples are single phase except the samples with x=6 and 7 which contain a small amount of impurity. The substitution of Mn for Co leads to a monotonic increase in unit cell volume. The saturation magnetization at 5 K remains nearly unchanged upon Mn substitution, while the Curie temperature decreases monotonically. XRD measurements on magnetically aligned powders with x=0–7 exhibit an easy-plane type of magnetic anisotropy at room temperature. For x=2, 3, and 4, spin reorientation transitions above room temperature are observed in the M–T curves. The magnetic phase diagram is given. © 2000 American Institute of Physics.

    Notes: The crystallinity, surface morphology, and I-V characteristics of the Ag thin films deposited on fractal substrates by rf magnetron sputtering have been investigated. The poor crystallinity, fractal surface morphology, and abnormal nonlinear I-V behavior of the thin films have been observed. The crystallinity of the films deposited on the fractal substrates is improved by increasing the substrate temperature and the thickness of the thin films. The nonlinear I-V characteristics are influenced by the thickness of the thin films, substrate temperature, and measuring environment.

    Notes: Samples of (Pr1−xCex)6Fe13Al (x=0.1, 0.2, 0.3, 0.4, 0.5, and 0.6) were prepared by arc melting and annealed for two weeks at 973 K. The x-ray diffraction patterns show that all the samples crystallize with the Nd6Fe13Si-type structure. The unit-cell volume increases first and then decreases as the Ce content increases. The Curie temperature and the spontaneous magnetization decrease almost linearly with increasing Ce concentration, supporting the existence of a mixed valence of Ce3+ and Ce4+. The series is ferromagnetic at high temperature; however, the peak at low temperature of the M–T curve most likely corresponds to spin-glass behavior. © 2000 American Institute of Physics.

    Notes: The influence of Mn substitution for Fe on the structure and magnetic properties of Pr2Fe17−xMnx compounds with 0≤x≤9 was investigated. X-ray diffraction indicates that all samples are single phase with the rhombohedral Th2Zn17-type structure. The unit cell volume V remains nearly constant with increasing manganese content up to x=2, then increases linearly at a rate of about 2.5 Å3 per Mn atom up to x=8 and there is a large increase of cell volume at x=9. The Curie temperature increases a little from 298 K at x=0 to 308 K at x=1, and then decreases to 37 K at x=9 quickly. The saturation magnetization at 5 K was found to decrease monotonously with increasing Mn concentration. The thermal magnetization curves M(T) of the compounds with x=1–9 show a strong decrease below TC with decreasing temperature. Also it presents considerable magnetic hardness at low temperature. This can be attributed to the presence of narrow Bloch walls. © 1999 American Institute of Physics.
