This paper evaluates two-dimensional turbo product codes based on single-parity check codes (TPC/SPC) and low-density parity check (LDPC) codes for use in digital magnetic recording systems. It is first shown that the combination of a TPC/SPC code and a precoded partial response (PR) channel results in a good distance spectrum due to the interleaving gain. Then, density evolution is used to com...

An eight-week feeding trial was conducted to evaluate the effects of soy isoflavone and saponin on growth performance, intestinal structure, immunity gut microbiota community rice field eel Monopterus albus (initial weight 20.12 ± 0.15 g). Six isonitrogenous isolipidic experimental feeds were formulated, including a positive control (55% fish meal, FM), negative (28.6% 37.2% soybean SBM) basic ...

Product quality strongly depend on production process quality. So, performance of production process must be strictly monitored. Statistical Process Control (SPC) is a technique used for evaluate process performance using statistical method to analyze, control, and influence process performance improvement. Combined of two control chart, individual chart and cusum chart could improve performanc...

AN INTEGRATED APPROACH TO PROCESS CONTROL A discussion of Statistical Process Control, Total Productive Maintenance, and Automated Process Control in production processes. The control of production processes is the subject of several disciplines, such as Statistical Process Control (SPC), Total Productive Maintenance (TPM), and Automated Process Control (APC). Although these disciplines are tra...

Type 2 diabetes mellitus (T2DM) is a progressive condition requiring long-term treatment. Most patients with T2DM are unable to maintain normoglycemia using metformin alone; thus, combination therapy is a pivotal part of disease management. Addition of the dipeptidyl peptidase-4 inhibitor linagliptin, with its proven efficacy, low propensity for hypoglycemia, and weight neutrality, has been sho...

With recent advances in Information Technology (IT), research on and the practice of information sharing are exerting significant effects on many aspects of individual members in a multi-stage process or a supply chain. This research looks at how information of Statistical Process Control (SPC) and Engineering Process Control (EPC) is shared along a supply chain on a real-time basis for product...

OBJECTIVE A variety of postmarketing surveillance strategies to monitor the safety of medical devices have been supported by the U.S. Food and Drug Administration, but there are few systems to automate surveillance. Our objective was to develop a system to perform real-time monitoring of safety data using a variety of process control techniques. DESIGN The Web-based Data Extraction and Longit...

Statistical Process Control (SPC) has long been used to monitor and control the performance of manufacturing processes. Its benefits in this arena are well known. By comparison, little attention has been paid to the use of quantitative tools for monitoring and controlling service processes, other than accounting data in financial reports and the use (and abuse) of numerical ratings in personnel...

Conventional statistical process control (SPC) charts require the normality assumption on the process response distribution. In reality, this assumption is often invalid. In such cases, it has been well demonstrated in the literature that results from control charts using the normality assumption may not be reliable in the sense that their actual false alarm rates could be substantially larger ...

Inventory replenishment rules contribute significantly to the bullwhip effect and inventory instability in supply chains. Smoothing replenishment rules have been suggested as a mitigation solution for the bullwhip effect but dampening the bullwhip effect might increase inventory instability. This paper evaluates a real-time inventory replenishment system denoted as SPC that utilizes a control c...
