Based on analyzing the process capability indices, a production department can trace and improve a poor process to enhance quality levels and satisfy customers. The process capabilit y analysis can also serve as an important reference for making decisions for imp roving the global quality of all products. Since C p and C pk are failed to account for process centering, the index C pm is developed. The index C pm takes the process centering into consideration and is su itable for the processes with nominal-the-best type. There are other indices l ike C pu and C pl, and those indices are used for unilateral s pecification processes. Chou (1994) developed a procedure using estimators of C p, C pu and C pl for practitioners to determine whether two p rocesses are equal capability or not. For bilateral specifications processes, i ndex C p is failed to measure process yield and process centering. Thus, th e index C pm is used to develop a similar procedure for practitioners t o determine whether two processes are equal capability or not. The decisions mad e using the procedure to select the better supplier are, of course, more reliabl e.展开更多

The results indicate that shorter treatingtime, decrease of NaCN consumption of 60/100 and increase of goldleaching rate of 15/100 can be ob- tained by the ultrafine millingtechnology compared with traditional cyanide leaching. Potentialexists for the new pro- cess to form the basis for an economicallyprocess for treatment of gold-bearing sulphides.展开更多

We present the design and implementation of a instrument localization system that is based on information fusion strategies to enhance its recognition power. The system was implemented using RFID technology. It monitored the presence of surgical tools in the interventional site and the instrument tray and combined the measured information by applying redundant, complementary, and cooperative information fusion strategy to achieve a more comprehensive model of the current situation. An evaluation study was performed that showed a correct classification rate of 97% for the system.展开更多

In this paper, based on the in\|situ high\|resolution observation data of GAME\|Tibet, the soil energy\|moisture distribution and the melting\|freezing progresses and their effects on seasonal shift were preliminarily discussed.The soil energy\|water distribution and freezing\|melting processes varied at different sites in northern part of Tibetan Plateau. The temporal and spatial variation of the soil moisture content is more complex than that of temperature. The soil moisture content increased with depth in certain layers but decreased in other layers. The freezing and melting processes and the temperature distribution were largely influenced by the existence of higher soil moisture content layer. During summer monsoon, the soil moisture at 10cm at all sites is relatively high, but the spatial difference existed. Generally speaking, the shallow layers start to freeze in October and to melt from April at all sites, with about 6 months frozen period. However, the beginning time of freezing\|melting and frozen period varied at different sites.展开更多

According to the schema theory, comprehending a text is an interactive process between the reader's prior knowledge(top-down processing) and the text(bottom-up processing). Both top-down and bottom-up processing are necessary for the inferring in reading comprehension. This paper explores how good and poor Chinese learners adopts top-down processing and bottom-up processing to make inferences in L2 reading, and finds some differences and similarities in using textual materials and background knowledge to make inferences in L2 reading by good and poor Chinese EFL learners respectively.展开更多
