    Systematic failure mode effect analysis (FMEA) using fuzzy linguistic modelling (2005)

    Notes: Purpose - To permit the system safety and reliability analysts to evaluate the criticality or risk associated with item failure modes. Design/methodology/approach - The factors considered in traditional failure mode and effect analysis (FMEA) for risk assessment are frequency of occurrence (Sf), severity (S) and detectability (Sd) of an item failure mode. Because of the subjective and qualitative nature of the information and to make the analysis more consistent and logical, an approach using fuzzy logic is proposed. In the proposed approach, these parameters are represented as members of a fuzzy set fuzzified by using appropriate membership functions and are evaluated in fuzzy inference engine, which makes use of well-defined rule base and fuzzy logic operations to determine the criticality/riskiness level of the failure. The fuzzy conclusion is then defuzzified to get risk priority number. The higher the value of RPN, the greater will be the risk and lower the value of RPN, and the lesser will be the risk. The fuzzy linguistic assessment model was developed using toolbox platform of MATLAB 6.5 R.13. Findings - The applicability of the proposed approach is investigated with the help of an illustrative case study from the paper industry. Fuzzy risk assessment is carried out for prioritizing failure causes of the hydraulic system, a primary element of the feeding system. The results provide an alternate ranking to that obtained by the traditional method. It is concluded from the study that the fuzzy logic-based approach not only resolves the limitations associated with traditional methodology for RPN evaluation but also permits the experts to combine probability of occurrence (Sf), severity (S) and detectability (Sd) of failure modes in a more flexible and realistic manner by using their judgement, experience and expertise. Originality/value - The paper integrates the use of fuzzy logic and expert database with FMEA and may prove helpful to system safety and reliability analysts while conducting failure mode and effect analysis to prioritize failures for taking corrective or remedial actions.

    Stress induced phosphate solubilization in bacteria isolated from alkaline soils (2000)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 182 (2000), S. 0

    Notes: Phosphate solubilizing bacteria NBRI0603, NBRI2601, NBRI3246 and NBRI4003 were isolated from the rhizosphere of chickpea and alkaline soils. All four strains demonstrated diverse levels of phosphate solubilization activity under in vitro conditions in the presence of various carbon and nitrogen sources. Acid production may have contributed to phosphate solubilization, but was not the only reason for phosphate release into the medium. Among the four strains, NBRI2601 was the most efficient strain in terms of its capability to solubilize phosphorus in the presence of 10% salt, pH 12, or 45°C. The strains showed varied levels of phosphate solubilization when the effects of different sources of nitrogen were examined during growth. The presence of low levels of Ca2+ and EDTA in the medium enhanced phosphate solubilization.

    FLM to select suitable maintenance strategy in process industries using MISO model (2005)
    Bingley : Emerald
    Journal of quality in maintenance engineering 11 (2005), S. 359-374

    Notes: Purpose - To help the maintenance managers/decision makers to select a suitable maintenance strategy for the components/parts associated with the system. Design/methodology/approach - An approach based on fuzzy linguistic modeling is used to select the most effective and efficient maintenance strategy. Three input parameters, i.e. historical data (I1), present data (I2) and competence of data (I3) related to failures of a component (gears), were taken to judge the effectiveness of the nature of maintenance strategies. These parameters are represented as members of a fuzzy set, combined by matching them against (if-then) rules in rule base, evaluated in fuzzy inference system (Mamdani, min-max type) and then defuzzified to assess the capability or effectiveness of maintenance strategy. Findings - The results show how the fuzzy logic approach translates vague, ambiguous, qualitative and imprecise information into numerical/quantitative terms, which helps to identify the most informative and efficient maintenance strategy. From the computed performance index values for each maintenance strategy it is observed that proactive (CBM) and aggressive maintenance strategy (TPM) are far better compared with traditional, reactive (BDM) maintenance strategy. Originality/value - The paper integrates fuzzy logic modeling - a knowledge-based approach with database obtained through maintenance logs, historical records, equipment manuals and expert judgement, which might prove beneficial for maintenance managers/engineers/practitioners to select a suitable maintenance strategy for each piece of equipment associated with the systems.

    Immunomodulation following zinc supplementation during chelation of lead in male rats (1994)
    Springer
    BioMetals 7 (1994), S. 41-44

    ISSN: 1572-8773
    Keywords: chelation ; immune system ; lead exposure ; rat ; zinc depletion

    Notes: Abstract Influence of zinc supplementation (30 and 45 mg kg−1, orally once for 5 days) during chelation of lead (0.3 mmol kg−1, chelating agent, i.p., once for 5 days) on some selected variables of the immune system was investigated in male rats. Treatment with CaNa2EDTA either alone or in combination with zinc (30 mg kg−1) produced a significant recovery in lead induced alteration in primary antibody forming cells to T-dependent antigen and the delayed-type hypersensitivity response to bovine albumin. However, biologically significant recovery was observed only with zinc at a dose of 45 mg kg1. It is assumed that zinc depletion during lead exposure and chelation treatment lead to harmful effects on cellular proliferation by inhibiting DNA synthesis and various enzymes during mitosis. The zinc supplementation fulfills this requirement during proliferation and clonal expansion of immunocompetent cells augmenting the immune system.

    Magnetic and transport properties of 214 oxides: Dependence on doping (1994)

    Notes: Abstract We consider how doping can be described in terms of the charge-transfer insulator concept. We discuss and compare a few models for the band structure for the doped charges. This has led us to the conclusion that the band structure stability problem is one of the main issues in any correspondence between results for thet-J model and, say, the three-band model for the slightly doped layered oxides. The stability criterion is formulated and its implications discussed. Provided a phenomenological conduction band is chosen to satisfy the criterion of stability, a detailed picture of how dopants influence the spin wave spectrum atT=0 is presented. The basic physics for the destruction of the antiferromagnetic (AF) long-range order is rather model-independent: the long-range order (atT=0) disappears due to the Cerenkov effect when the Fermi velocity first exceeds the spin wave velocity. We then discuss the overall spectrum of spin excitations and see that the spin wave attenuation for x〈x c,T= 0 due to Landau damping appears in the range of magnon momentak(x)=2m * s±α√x. We also argue that in the presence of superconductivity, the Cerenkov effect is eliminated due to the gap in the spectrum. This may restore the role of the AF fluctuations as the main source of dissipation at the lowest temperatures. A brief discussion of how interaction with magnons may affect the hole spectrum concludes the paper.
