Current methods to compare measurement series are based on the comparison of multiple measurement points or fit parameters. These approaches depend on the quality of the fit and are prone to type I error accumulation, when standard statistical tests are used for evaluation. In this work, we present an approach based on a two-sample Kolmogorov-Smirnov test of residuals of data series to a fit in order...
The purpose of this study is to investigate the best practices in the transdisciplinary field of knowledge management system implementation and measurement of IT Complain in a telecommunication company (PT Telkomsel). This paper examines three variables of Knowledge Management (People, Process and Technology) and IT Complain Variable. This research used two methods such as a qualitative and quantitative...
In sight of the rapid revolutions of the information and wireless-transformation and telecommunication technologies since 2000s, most of people used to utilize the diversified computer, communication, consumer (3C) electronic devices, such as notebook, tablet PC and so on, to not only simultaneously surf and download the comprehensively public information and knowledge but also immediately share and...
Audio source separation models are typically evaluated using objective separation quality measures, but rigorous statistical methods have yet to be applied to the problem of model comparison. As a result, it can be difficult to establish whether or not reliable progress is being made during the development of new models. In this paper, we provide a hypothesis-driven statistical analysis of the results...
In the general sense, the reliability index is calculated by mathematical statistics method, in which, a large number of failure datas must be obtained by accelerated life test, and the most important thing is that the index is a static index, not reflecting the real-time reliability. This method is not appropriate for high precision products. In this case, performance degradation data based on running...
The study aims to predict the life and assess the reliability of electronic packages subject to multiple drop-impacts. Engineers used to adopt mechanics analysis as well as a certain life prediction model to predict the impact life of the package, and it is usually a deterministic value. However, drop test results show that the impact life of the package is not a single deterministic value but scatters...
From the view of customers' perception, this paper analyzes the factors effecting online shopping, and combines with empirical analysis method for research. Gathering information by the questionnaire survey, we use statistical analysis, such as reliability analysis, validity analysis, regression analysis. These results show that questionnaire design is reasonable ,the reliability and validity are...
A reliability growth model for 220 kV power transmission and distribution installations is presented. Ways for estimating and fitting on checking the model's parameters are given together analysis results concerning the reliability growth of six kinds of 220 kV power transmission and distribution installations, such as 220 kV power transformers, circuit breakers, isolating switches, surge arresters,...
Accelerated Life Testing (ALT) is an effective method of demonstrating and improving product reliability in applications where the products are expected to perform for a long period of time. ALT accelerates a given failure mode by testing at amplified stress level(s) in excess of operational limits. Statistical analysis (parameter estimation) is then performed on the data, based on an acceleration...
The human capital (HC) is the most important capital in the knowledge-based economy time, and the HC operations have certain impacts on enterprise performance. Based on the analysis of HC, HC operation and enterprise performance as well as literature research, the paper proposes the hypothesis of four dimensions of HC operations on effect of enterprise performance and constructs a structural equation...
We identified in-role and extra-role customer service and developed the scale for each based on Chinese retailing industry. Evidence suggested that both in-role and extra-role customer service were positively associated with customer satisfaction and loyalty. Opposite to our assumption, the in-role customer service had a stronger effect on customer satisfaction and loyalty than extra-role service...
Regarding to the problems of traditional reliability growth models, for example, Duane model, which have been used in the multiple stages reliability assessment. This paper firstly studied on the statistical analysis method of different stages and different level data based on sequence binding model, then modeled the change event of dynamic distribution parameters during test and gave the Bayesian...
Accelerated degradation test (ADT) is widely used to evaluate the reliability of highly reliable products with long life if there exists a product quality characteristic whose degradation over time can be related to reliability. It is still a main challenge that how to design optimal plan, including sample size, measurement frequency, and termination time, for ADT which can result in the most accurate...
According to analysis results of the failure modes of side-abrasion of rod strings for water-flood pump wells and the application of probability statistical and reliability theory, this paper properly treated and selected the failure data, and deduced the lifetime statistical model, realized qualitative analysis and quantitative evaluation for the working reliability. Through building the side-abrasion...
In the emerging global electronic market, the creation of customer centered Websites will become increasingly important. Based on the previous studies and empirical research, this paper proposes a hypothetic model of factors of influence customer satisfaction for E-commerce Websites, then, hypotheses are raised and tested by factor analysis. The result shows that Website design, information quality,...
Either for hardware or software repairable system, reliability analysis is very important. However, failure data analysis for repairable system is not an easy task. The widely used AMSAA model (power law process) is a kind of NHPP, corresponding to minimal repair. According to the variety of the reliability of repairable systems, accounting for the influences of the modification and repair, the repair...
Consumers' loyalty is essential to the enterprises' success in e-commerce. In order to find out which factors have impact on consumer loyalty, a literature review was employed using content analysis and a "7C" model of consumer loyalty in B2C e-commerce was built. Then we did an empirical research to prove the reliability of the model. A questionnaire wad designed and data were collected...
This paper develops and demonstrates a taxi pre-alarm system which is based on transportation hub information platform and urban taxi information platform and running in transportation hub in order to maintain continuous, enough and rational taxi supply and aiming at improving the taxi service lever of transportation hubs. The system is mainly made up of three key models: real-time taxi-demand estimate...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
The dramatic increase in leakage current, coupled with the swell in process variability in nano-scaled CMOS technologies, has become a major issue for future IC design. Moreover, due to the spread of leakage power values, leakage variability cannot be neglected anymore. In this work an accurate analytic estimation and modeling methodology has been developed for logic gates leakage under statistical...
