Identical Product

A simplified process monitoring system is implemented for process performance analysis. The concept of system is designed to deal with the reuse information from conventional measurement inspection of electronic piece parts. The analytical process depicts the principle of Statistical Process Control (SPC) to manipulate the preliminary data in the database from measurement machines in a real-time manner. The system will firstly generate a comparison graphical data from a particular process which then produces an identical product from the multiple machines. Finally, the system can distribute a variety of reports desired as described in the index of data storage as part of the measurement matrix. The report aims to guide the process improvement as well as the Measurement System Analysis for total quality control.

Virtual Sensei Lite (VS Lite) is an inexpensive user-friendly motion analysis system. As an alternative motion capture system, it is a must for VS Lite’s user to assess the accuracy of the measurement system capability. To date, such analysis to observe the reliability and accuracy of VS Lite has not been reported. Therefore, this study proposes a procedure for assessing the accuracy and capability of the Virtual Sensei Lite using ANOVA Gage Repeatability and Reproducibility (Gage R&R) designed experiments. In this procedure, a gage R&R study is conducted to obtain replicate measurements on nine parts by three operators. The total variation due to measurement error is then observed to identify the accuracy of measurement. The study able to demonstrate on the accuracy of VS Lite as the value of total variation due to measurement error is within 10%-30%.

<p><strong>Purpose:</strong> To clarify the different types of data likely to occur in any service or industrial process, the main applicable statistics for each type of data and the Six Sigma metrics that allow characterising and benchmarking organisational processes.</p><p><strong>Methodology/Approach:</strong> A short reference to the statistical process control is carried out, from Shewhart’s works to Motorola’s achievements, followed by a short discussion of the use of Six Sigma tools as a part of today’s total quality approaches, and by a discussion of the continuous, attribute and counting data worlds and their main applications in process analysis. Because many quality professionals may have difficulties dealing with engineering perspectives, a review of main classic and Six Sigma process metrics is done with examples. Complementing discussions, four functions written in the R language are presented, which can deal with real organisational data, or can be used for training purposes.</p><p><strong>Findings:</strong> The functions developed provide useful graphical displays and calculate all necessary metrics, having the ability to let the user provide theoretical values for training activities. Real and simulated case studies help understanding data worlds and respective Six Sigma metrics.</p><p><strong>Research Limitation/implication:</strong> This paper reports an intentionally simple theoretical perspective of Six Sigma metrics and friendly software which is available to all interested professionals on request to the authors.</p><strong>Originality/Value of paper:</strong> The paper presents clear definitions of main data types and metrics and is supported by a set of four new functions that can be used by any researcher with a minimum knowledge of the R software.

<p><strong>Abstract.</strong> In the big data era, real-time log data analysis is becoming the important demands for Internet enterprises, behind these data hiding big value. Map Word, the National Platform for Common GeoSpatial Information Services in China, is a one-stop website providing geospatial information services to personal users, enterprises, professional agencies and governments. After 7 years’ development of the platform, the traffic increased significantly, reaching 200 million service requests per day. But due to the lack of effective analysis and processing technology, the log data did not play its value, which lead to disconnection between the top-level design of national common geospatial information services and the actual demands of the users in a way. Now, the geospatial information service in China is trying to shift from the data production driven to the demand driven actively, and how to understand the demands of users became one imperious issue for research. In addition, the access behaviour of group users to common geospatial information services has a social nature and there is a certain group access behaviour pattern. This mode has high intensity of access aggregation and spontaneity, and determines the demand of common geospatial information services for cloud computing resources. Parts of the above demands can be analysed from the log data. Therefore, how to develop a log analysis system for unified real-time collection, real-time analysis, centralized storage, and graphical display is the key to support the demands. Flume, Kafka, Storm, Redis and HBase have been integrated to design and implement a distributed real-time log analysis system supporting online and offline log analysis. The system is composed of log collection module, asynchronous communication module, real time analysis and calculation module, data cashing and storage module, and visualization module. The system was release and integrated with Map World in June 2017 successfully, and the implementation of the system indicates that it can efficiently solve the problems of real-time log data collection, real-time analysis, real-time storage, real-time query, massive data storage, offline analysis, etc. It played an important role in map data update, policy making, product decisions, online server load prediction, resource allocation optimization, Internet security improvement and operation funs evaluation.</p>

Ecg Data

Cardiovascular disease is one of the major diseases that threaten the human health. But the existing electrocardiograph (ECG) monitoring system has many limitations in practical application. In order to monitor ECG in real time, a portable ECG monitoring system based on the Android platform is developed to meet the needs of the public. The system uses BMD101 ECG chip to collect and process ECG signals in the Android system, where data storage and waveform display of ECG data can be realized. The Bluetooth HC-07 module is used for ECG data transmission. The abnormal ECG can be judged by P wave, QRS bandwidth, and RR interval. If abnormal ECG is found, an early warning mechanism will be activated to locate the user’s location in real time and send preset short messages, so that the user can get timely treatment, avoiding dangerous occurrence. The monitoring system is convenient and portable, which brings great convenie to the life of ordinary cardiovascular users.
