The goal of this study was to investigate the manufacturing error correction model of the wavelet transform processor (WTP) using surface acoustic wave (SAW) devices. The motive of this work was prompted by the output accuracy of the WTP using SAW devices varying with the manufacturing accuracy of each finger of the devices. Thus, in this paper, we presented the functional relationship between ...

the main objective of this study is to investigate the production factors productivity in large manufacturing sub-sectors. for this purpose, using statistical data for period 1972-2004, we have tried to study and analyze the trend and level of production factors productivity (partial and total productivity) in each sub-sectors classified according to isic two digits code. the average and margin...

BACKGROUND "Lean" is a set of principles and techniques that drive organizations to continually add value to the product they deliver by enhancing process steps that are necessary, relevant, and valuable while eliminating those that fail to add value. Lean has been used in manufacturing for decades and has been associated with enhanced product quality and overall corporate success. OBJECTIVES...

In this environment, evaluations of manufacturing partners and integrated production-planni...

knowledge of surgery is one of the milestones in islamic civilization. the purpose of this study was to find principles and proven techniques used by muslim surgeons, third to twelfth century ah. the present study, enjoying a historical approach, used a descriptive analysis method with matching samples. the findings of the study revealed that, during this period, some of the principles and tech...

Manufacturing of composite laminates using the fiber placement process introduces possibility several types defects and features that are not present in traditional hand-layup fabrication techniques. The effect these on structural performance failure has been fully investigated, especially for those with small geometrical features. innovation lies advanced methods to capture generated during ma...

Performance evaluation studies in manufacturing systems have traditionally considered models in which the arrival process and service process are time independent. Real-world manufacturing systems however, are subjected i o highly complex and usually tamedependent input workloads. This motivates the study of performance models of manufacturing systems under non-stationary conditions. In this pa...

Natural food pigments are commonly utilized for the improvement of the qualitative properties of foods and/or inhibit the development of chronic and degenerative diseases. Several studies have documented the beneficial health effects of natural food pigments, such as anthocyanins, chlorophylls, and carotenoids. These effects mainly depend on the stability, bioactivity, and bioavailability of th...
