In modern office buildings, the customary trend is to use state of the art technology to ensure the users find it thermally comfortable, among other variables. Among the various statistical studies on comfort index vs. work efficiency of users, the most widely adopted index is the Predicted Mean Vote (PMV). Based on this index, this work proposes a control scheme that shows the capability of ne...

Greenwich and Jahr-Schaffrath (1995) introduced an index Cpp, a simple transformation of the index C∗ pm, which provides an uncontaminated separation between information concerning the process accuracy and process precision. Unfortunately, the index Cpp inconsistently measures process capability in many cases and thus reflects process potential and performance inaccurately. In this paper, we co...

every firm learns through firm specific methods. this learning process is operationalized by firm’s knowledge management practices. therefore, knowledge to result in successful learning should be assisted by a combinative framework which can enhance a firms’ absorptive capability. this in turn will play a decisive role for achieving competitive advantage. current literature in strategic managem...

Process capability indices are designed to describe how the process of interest can achieve to meet specification limits under a condition of statistical control. One of the capability indices is denoted as Cpm proposed by Chan, Cheng and Spiring (1988), sometimes termed the Taguchi index. The primary goal of this paper attempts to construct a confidence interval for Cpm, which measures proces...

The properties of Cpmk in the presence of asymmetric specification limits are discussed. It is shown that Cpmk tends to zero as the process variation increases and vice versa. Furthermore, if the process variation is small, Cpmk has its maximum near the target value but the maximum moves towards the specification midpoint as the variation increases. This is a desirable property as for large var...

The generalized yield index CT pk establishes the relationship between the manufacturing specifications and the actual process performance, which provides a lower bound on process yield for two-sided processes with multiple characteristics. The results attended are very practical for industrial application. In this article, we extended the results in cases with one-sided specification and multi...

the past, the process capability index (PCI) was the only one used in on-line quality management; there were no researches on off-line applications, such as product design or process planning. In using conventional PCI for off-line application, designers normally established the process mean close to the design target, and minimized the process variance so that the PCI value would be maximized....

An infrared refractive index sensor based on plasmonic perfect absorbers for glucose concentration sensing is experimentally demonstrated. Utilizing substantial absorption contrast between a perfect absorber (∼98% at normal incidence) and a non-perfect absorber upon the refractive index change, a maximum value of figure of merit (FOM*) about 55 and a bulk wavelength sensitivity about...
