Statistical process control (SPC) is an approach to process control that has been widely used in any industrial or non-industrial fields. SPC is based on so called Shewhart ́s conception of the process variability. This conception distinguishes variability caused by obviously effected common causes (process is considered to be statistically stable) from variability caused by abnormal assignable ...

The history of technological developments affects the way we can provide services to customers quickly. One methods industrial Control Systems is statistical process control method (SPC) for short-term production. This review aims explain some advantages SPC method, namely in terms monitoring multistage processes and fault diagnosis has become a necessity. by Entering control. hybrid approaches...

OBJECTIVES To describe the characteristics of Western Australian (WA) people who received, and did not receive, specialist palliative care (SPC) during their last 12 months of life. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS People who died between 1 July 2000 and 31 December 2002 in WA, and whose cause of death was from cancer or selected non-cancer conditions. MAIN OUTC...

Objective. To evaluate the efficacy and safety of the telmisartan plus amlodipine (T/A) single-pill combination (SPC) in Asian patients with hypertension whose blood pressure (BP) was not adequately controlled on either monotherapy or on low-dose combination therapy. Patients and Methods. Data are presented from five Boehringer Ingelheim-sponsored phase 3, double-blind, 8-week, studies: two stu...

In an Escherichia coli strain lysogenic for lambda spc2 transducing phage, an extra copy of ribosomal protein (r-protein) genes in the spc and alpha operons are carried on the phage chromosome. Expression of genes in the spc operon in this merodiploid strain was compared with that in a control "haploid" strain carrying lambda trkA phage. It was found that the synthesis rate of spc mRNA, relativ...

Background: A systematic review is a rigorous method for assessing and aggregating research results. Unlike an ordinary literature review consisting of an annotated bibliography, a systematic review analyzes existing literature with reference to specific research questions on a topic of interest. Objective: Statistical Process Control (SPC) is a well established technique in manufacturing conte...

A novel single-point technique to calculate local arterial wave speed (SPc) has recently been presented and applied in healthy human coronary arteries at baseline flow. We investigated its applicability for conditions commonly encountered in the catheterization laboratory. Intracoronary pressure (P(d)) and Doppler velocity (U) were recorded in 29 patients at rest and during adenosine-induced hy...

This paper presents a supervisory generalized predictive control (GPC) by combining GPC with statistical process control (SPC) for the control of the thin film deposition process. In the supervised GPC, the deposition process is described as an ARMAX model for each production run and GPC is applied to the in situ thickness-sensing data for thickness control. Supervisory strategies, developed fr...

In recent years, the integration of Statistical Process Control (SPC) and Engineering Process Control (EPC) has received considerable attentions due to the superiority for the process improvement. However, a drawback of the integration of SPC and EPC may be encountered for monitoring a process. Because EPC would compensate for the effects of underlying disturbances, the disturbance patterns cou...

Statistical process control (SPC) is a powerful technique for monitoring, managing, analyzing and improving process performance by statistical methods. Unfortunately, LCD industry cannot control key factors in the application process, and do not invest adequately in resources. Therefore, the performance matrix is adopted to locate those objective items outside the appropriate performance zones ...
