Goal. To create a mathematical tool for assessing the quality of a complex system likely availability (or failure) in the presence of interrelation in the components operation. The tool is different from the Markov's chain and other analogs. Tasks. To introduce a binomial distribution as the sum of the probabilities of ordered subsets of the numbers of successful tests. Introduction to probability...
For the multi-index decision problem with uncertain information, this paper introduces the definition of interval distance of three-parameter interval grey number, proposes the relative degree of grey incidence based on interval distance of three-parameter interval grey number, constructs the grey incidence decision-making model with three-parameter interval grey number, measures the relative degree...
online social networks are progressively being adopted among young people in developing countries. The public is questioning why so many people adopt this technology in many aspects of their lives? The purpose of this study is to understand the acceptance of social networks by Thai students. We used traditional TAM's behavioral constructs: subjective norms (SN), perceived usefulness, perceived ease...
Accurate unsupervised tampering localization is one of the most challenging problems in digital image forensics. In this paper, we consider a photo response non-uniformity analysis and focus on the detection of small forgeries. For this purpose, we adopt a recently proposed paradigm of multi-scale analysis and discuss various strategies for its implementation. First, we consider a multi-scale fusion...
This study aims to generate empirical evidence on the validity and reliability of Perception of Online Collaborative Learning Questionnaire (POCLQ) using Rasch model. The questionnaire was distributed to 32 (N=32) Diploma Hotel Catering students from Politeknik Ibrahim Sultan, Johor (PIS). Data obtained was analysed using WINSTEP version 3.68 software. The finding showed that POCLQ had high reliability...
This study investigates the relationships between students' perceptions and their online behaviors after they were engaged in collaborative knowledge building activities for social studies. One hundred and seventy seven Singapore primary three and primary four students participated in this study and the results show that when interpreting students' collaborative knowledge building, their perceptions...
Evaluation of construction or renovation projects is necessary for the developing of distribution network. A comprehensive evaluation can contribute to find problems in the process of projects and promote scientific level of decision making for future construction or renovation. In this paper, we propose a post evaluation for distribution network. Firstly, we put forward an integrated index system...
General technique of template data preparation is proposed for the tasks of visual correlation-extreme navigation, which includes the image and its descriptive representation. Descriptive representation is based on Speed-Up Robust Feature (SURF) method. The requirements and structure of database of unified template are developed including the integral index of fragment informativity. Experimental...
Data mining is to extract the potentially useful knowledge and information from large amounts of data. How to dig up effective, reliable, understandable, and interesting association rules from vast amounts of information to help people make decisions has become an urgent problem to be solved. People want to use a reasonable evaluation method to measure reliability or validity of association rules,...
Power distribution networks are increasing, more complex and therefore should provide maximum reliability to its customers. Susceptible to interruptions, defects and malfunction for various reasons, investments in improving distribution network quality are increasing and should be performed based on environment conditions, technical requirements, demands and needs. This paper presents a new methodology...
Safety culture construction has significant impact on fire prevention in oilfield. Reasonable evaluation index system should be set up to evaluate the state and quality of safety culture construction in oilfield enterprise teams while further study should be taken and validated on spot. Framework of safety culture construction in Oilfield enterprise teams was put up. By SMART principle and occupation...
The purpose of this research paper is to examine the relationship between self-concepts relating to two attributes necessary for successful engineers in today's society: creativity and global readiness. Some previous studies have shown a positive relationship exists between multicultural exposure and later creative performance. However, no studies were found that examine the relationship between students'...
During the groups of decision making progress, according to the preference requirement that decision-makers emphasized and the vagueness of the evaluation information, this article describes how to use a method based on two-tuple linguistic to rank the weightiness of the competitive intelligence evaluation indexes and convert qualitative assessment to quantitative evaluation. Using this method, the...
This paper presents an accelerated state evaluation (ASE) in sequential simulation for composite system reliability analysis, with the consideration of bus load correlation. The ASE computes a threshold load level at each sampled component state and uses it to identify load-loss states efficiently. As such, the number of load curtailment computations involving optimal power flow can be greatly reduced...
Shot segmentation is an important preprocessing step towards content based video analysis. In this paper, we propose a Spatio-Temporal Fuzzy Hostility Index (STFHI) for determining the edges of objects present in the frames, composing the video. The edges present in the frames are treated as features of the frame. The correlation between the features is computed for successive frames of the video...
In this article we introduce a new strategy for optimal diversification which combines elements of Diversified Risk Parity [1], [2] and Diversification Ratio [3], with emphasis on positive risk premiums. The Uncorrelated Positive Bets strategy involves the identification of reliable, independent sources of randomness and the quantification of their positive risk premium. We use principal component...
We consider the problem of inferring the conditional independence graph (CIG) of a multivariate stationary dicrete-time Gaussian random process based on a finite length observation. Using information-theoretic methods, we derive a lower bound on the error probability of any learning scheme for the underlying process CIG. This bound, in turn, yields a minimum required sample-size which is necessary...
This study found a positive correlation between dual commitment and positive industrial relations climate while a negative correlation between dual commitment and negative industrial relations climate according to a questionnaire survey with 610 samples in several Wuhan's private enterprises. With a further research by using the Logistic regression model, the affective commitment, normative commitment...
The current literatures seldom talk about the multilevel impact of transformational leadership (TFL) on employee service quality and the influence of mediation mechanism between transformational leadership and employee service quality. This study aims to discuss the impact of transformational leadership on employee service quality in terms of individual perspective and branch perspective respectively...
This paper presents analyses of data in view of obtaining a possible correlation between geomagnetic activity and protection trips in a 138 kV–197.12 km power transmission line in southern Brazil. Most of these outages are caused by faults randomly located along the line. In consequence, many studies have been done to identify the main reason for these events, now including the investigation of the...
