Jiang Keywords: Deterioration; Production-inventory model; Replenishment policy Abstract: In this note we examine the total cost function of a single-vendor multiple-buyers production-inventory policy for a deteriorating item by Yang and Wee [P.C. Yang and H.M. Wee, A single-vendor multiple-buyers production-inventory policy for a deteriorating item, European Journal of Operational Research 143 (2002) 570-581]. Two possible flaws in the cost function of Wee and Yang's model are pointed out. A proposal to eradicate the flaws is given.

The ferroelectric thin films have a single-crystal structure. Surface structure had a big influence on the microstructure of thin films.

Research describing the characteristics of epitaxial strontium ruthenate thin films is presented. Observations by atomic force and transmission electron microscopy are analysed.

Characterization of protonated formamide clusters by vibrational predissociation spectroscopy confirms theoretical predictions that O-protonation occurs in preference to N-protonation in formamide. Results of the work carried out suggest an interesting possibility of C-H...O bond formation in the protonated formamide trimer.

The microstructure of nitride layers of AISI 316 stainless steel produced by intense plasma assisted processing is examined.

Ti atomic bonding environment in Ti-containing hydrocarbon coatings was examined using x-ray absorption near edge structure spectroscopy.

Research was conducted to examine the influence of lattice stress relaxation on the microstructures of epitaxial thin films through domain structure investigations of epitaxial SrRuO3 thin films developed on vicinal (001) SrTiO3 substrates using transmission electron microscopy and x-ray diffraction. Results indicate that the lattice strain relaxation has a crucial effect on the microstructures and characteristics of epitaxial thin films when the substrate material is taken.

Discusses thick film resistors as an alternative to thin-film platinum temperature sensors. Resistance and resistivity; Transmission electron microscopy characterization; Microscopic composition and crystallography; Role of morphology on temperature coefficient resistance.

A series of TiN/Ti multilayer coatings with TiN layer thickness and different Ti layer thicknesses are deposited by using a large area filtered arc deposition method. The studies have shown that the reduction in the defect density in both TiN and Ti layers and the relaxation of the stain by the diffusion of the Ti atoms in the underneath Ti layer has contributed to the decrease in the total internal stress with increasing Ti layer thickness.

The microstructural evolution of Co-DLC nanocomposite films as a function of Ar/CH4 flow ratio in the discharge and chamber pressure is investigated. Present evidence indicates that the Co nanorod formation is under kinetic control.

Investigates the clustering of water on protonated molecular ions by vibrational predissociation spectroscopy. Resemblance of the hydroxide stretch spectra in the protonated ion-water clusters; Supersonic expansion of the ions to establish complexation with water.
