Economic manufacturing quantity,optimum process mean,and economic specification limits setting under the rectifying inspection plan

Economic manufacturing quantity, process mean, and specification limits setting are three important methods for the inventory and quality control problems. In the imperfect production system, we usually consider the manufacturing quantity for reducing the inventory cost, determine the process level for reducing the production cost, and select the specification limits for screening the products. In this paper, we propose the above integrated model based on the application of rectifying inspection plan for obtaining maximum expected total profit of product. The asymmetric quadratic quality loss function is adopted for measuring the product quality. The sensitivity analyses of parameters are provided for illustration.     

An equity approach to stream water quality management

A model for stream water quality management with particular emphasis on applicability in Turkey is developed via mathematical programming. A new criterion of equity is introduced and the model is formulated as a quadratic programming problem with two objectives, namely equity among dischargers and minimization of total cost. The model is also applied to a hypothetical stream and compared with other more common water quality management programs.

X-Ray Tube Voltage Dependence of Wiener Spectra of Screen Structure Mottle Recorded on Front and Back Emulsions

A low-speed screen/film system was used to investigate structure mottle, i.e., the density fluctuation of an x-ray film due to inhomogeneous screen structure. The tube voltage dependence of the Wiener spectra of the structure mottle was separately determined for front and back film emulsions. The Wiener spectral values of the structure mottle of the front emulsion were greater than those of the back emulsion at lower tube voltages. The spectral values of the structure mottle of the front emulsion decreased with tube voltage, while those of the back emulsion increased. We explain these phenomena by the behavior of the Wiener spectra of the relative spatial fluctuation of fluorescence intensity due to following reasons: (1) spatial thickness fluctuation of the screen produces a relative spatial fluctuation of x-ray energy absorbed in the screen, and (2) as the distance between the emulsion of the film and the average position of the x-ray absorption in the screen lengthens, the number of random scattering and absorption of light photons increase.Presented at the International Commission for Optics Topical Meeting, Kyoto, 1994.     

高压截获十次准晶相关晶体相和纳米级超微粒

 对Al₇₀Co₁₅Ni₁₀Tb₅合金进行了静高压（7.0 GPa）熔态（1 700 ℃）淬火（冷却速率10²⁰ C/s）处理，首次观察到一个新十次准晶相关晶体相。该相属底心正交晶体，晶胞参数为a=2.28 nm、b＝1.60 nm、c＝5.46 nm。通过高分辨像分析，给出了它的二维点阵模型。同时在样品中发现了尺寸均匀的纳米级非晶超微粒形成，超微粒为球形，直径30~40 nm。
