The present paper deals with the opportunities for the availability predictive modeling of a thermal plant using Markov process and probabilistic approach. These opportunities will be identified by evaluation of a predictive model to be built for the steam generation system of a thermal power plant. This feasibility study covers two areas: development of a predictive model and evaluation of performance with the help of developed model. The present system under study consists of five subsystems with three feasible states: full working, reduced capacity working and failed. After drawing transition diagram, differential equations are generated and then a probabilistic simulated predictive model using Markov approach has been developed considering some assumptions. Availability matrix for each subsystem is also developed, which provide various availability levels. On the basis of this study, performance of each subsystem of steam generation system is evaluated and then maintenance decisions are made for subsystems. © 2010 World Scientific Publishing Company.

In the present study, a novel heterobimetallic [Mg(II)-Sn(IV)]-μ- oxoisopropoxide [MgO2Sn2(OPri)6] and its β-diketonates have been synthesized and characterized. The parent compound has been synthesized by the thermal condensation of magnesium acetate and tin(IV) isopropoxide. The isopropoxy substitution reactions of μ-oxoisopropoxide compound with β-diketones in different molar ratios (1:1-1:4) yielded the mono derivatives to tetra derivatives respectively of the parent compound. [{MgO2Sn2(OPri)6-nLn} (where n is 1-4 and L = acetylacetonate/ benzoylacetonate anion)]. The μ-oxoisopropoxide compound has been characterized by liberated isopropanol, elemental, spectral (IR, 1H, 13C, 119Sn NMR, and mass), thermal analysis, molecular weight data, and plausible structure is suggested. Some important reactions of [MgO2Sn2(OPri)6] with different β-diketones have revealed interesting facets in support of the suggested structure. The β-diketonates have been characterized by elemental, liberated isopropanol and spectral analysis (IR, 1H, 13C NMR). © 2014 Copyright Taylor and Francis Group, LLC.

New Salicylate derivatives of organoheterobimetallic-μ- oxoisopropoxide [Bu2SnO 2Ti 2(OPr i) 6] have been synthesized by the thermal condensation μ-oxoisopropoxide compound with different salicylates in different molar ratios (1:1-1:4) yielded the compounds of the type [Bu 2SnO 2Ti 2(OPr i) 6- n(RSal) n] (where n is 1-4 and RSal = Salicylate anion) respectively. The μ-oxoisopropoxide derivatives have been characterized by elemental, liberated isopropanol and spectral analysis (IR, 1H , 13C, 119Sn NMR).

New Schiff base derivatives of organoheterobimetallic-μ-oxoisopropoxide [Bu 2SnO 2Ti 2 (OPr i) 6] have been synthesized by the thermal condensation ?-oxoisopropoxide compound with Schiff bases in different molar ratios (1:1-1:4) yielded the compounds of the type [Bu 2SnO 2Ti 2 (OPr i) 6-n (SB) n] (where n is 1-4 and SB=Schiff base anion) respectively. The μ-oxoisopropoxide derivatives have been characterized by elemental, spectral analysis (IR, 1H, 13C, 119Sn NMR) and molecular weight measurement The studies reveal that the derivative compounds show monomeric nature. Further these are found less susceptible to hydrolysis as compared to parent compound and may prove excellent precursors for the mixed metal oxides.

The experimental investigations of the delamination factor of glass fiber reinforced plastic at different cutting parameters are reported in this study. This paper has involved the determination of different factors affecting the hole quality and cause of delamination in a glass fiber reinforced plastic. The various process parameters like different twist drill bits of different materails, different point angle at different speed, feed rate have been taken. The thrust forces and torque values were measured using piezoelectric dynamometer. Mathematical model has been developed for different machining conditions using Minitab software with help of Taguchi design to plan the experiments. The Universal microscope has been used which determines delaminated diameter in GFRP specimens. The finite element method has been applied by using Ansys11.0 software which helped to find out delaminated diameter. It was experimentally observed that for the tungsten carbide and M50 drill bits, the thrust force and torque significant increases on increasing the point angle and feed rate.

A new heterobimetallic-μ-oxoisopropoxide of the type [SnO 2Ti2(i-OPr)6] has been synthesized by the thermal condensation of tin diacetate and titanium isopropoxide in 1:2 molar ratio in refluxing xylene. The isopropoxy substitution reactions of this μ-oxoisopropoxide compound with β-diketones in different molar ratios (1:1-1:4) gives compounds of the type [SnO2Ti2(i-OPr) 6-nLn] (where n is 1-4 and L = acetylacetonate/ benzoylacetonate anion). The μ,-oxoisopropoxide compound has been characterized by elemental, spectral analysis (IR, 1H , 13C, 119Sn NMR and mass) and molecular weight measurement. The β-diketonates of [SnO2Ti2(i-OPr)6] have been characterized by elemental, liberated isopropanol and spectral analysis (IR, 1H, 13C NMR).
