Herbal Medicine in Traditional Chinese Medicine (TCM) relies on interactions between ingredients of a prescription. The combination is chosen to promote desirable interactions. Analysing these interactions is important in quantitatively analysing effects of TCM on patient outcomes. The concept of interactions has not been adequately formulated before due to the ambiguity of “interaction” and the need...
Privacy Preserving Data Mining (PPDM) is receiving a lot of attention recently by researchers from multiple domains, especially in Association Rule Mining. The outputs of Association Rule Mining often involve values of attributes that can be used to characterize the identities of the users. The relations between antecedents and consequents are also explicitly displayed. The purpose of preserving association...
There is a growing concern about the increasing vulnerability of future computing systems to errors in the underlying hardware. Traditional redundancy techniques are expensive for designing energy-efficient systems that are resilient to high error rates. We present Error Resilient System Architecture (ERSA), a low-cost robust system architecture for emerging killer probabilistic applications such...
In prediction error identification, confidence regions are most commonly derived from the asymptotic statistical properties of the parameter estimator. Therefore, these confidence regions are only asymptotically valid and, for finite samples, their actual coverage rate can be smaller than the desired coverage rate. In this paper, we analyze the influence of the SNR and of the type of model structure...
This paper introduces a method to analyze the performance of a system through the rank correlation between the fuzzy probist reliability of its components. The fuzzy probist reliability of each component is obtained using restricted fuzzy algebra and linear programming technique. And the proposed method is illustrated by analyzing the performance of the Web page `Departments' of the Web site www.ssn...
The sequential probability ratio test (SPRT) is the most common acceptance test in the field of reliability and quality control of electronic systems. Proposed are measures of the test quality. One of them is the increase in the average sample number (ASN) caused by the test truncation. An optimality criterion based on it considerably facilitates solution of the problems in automatic planning of the...
Information Fusion is a valid way which can decrease the uncertainty of making decision, and is also a hotspot. The paper makes some work on a important problem about Fuzzy Integral, that is how to get the Fuzzy Density, and compares two typical means. Based on 11 UCI data set, this paper conducts the compared experiment of several Information Fusion methods. It is compared with references 4 and 5...
In this paper we study a reliable downloading algorithm for BitTorrent-like systems, and attest it in mathematics. BitTorrent-like systems have become immensely popular peer-to-peer file distribution tools in the Internet in recent years. We analyze them in theory and point out some of their limitations especially in reliability, and propose an algorithm to resolve these problems by using the redundant...
Mine hoisting accidents, as common and frequent disasters, the statistics shows 90% of them are caused by human errors. Therefore, studying human reliability of the systems can effectively reduce systems failure due to human errors. Although the significance of human reliability has been widely acknowledged, this technology, currently restricted to aerospace, aviation, nuclear industry, is not prevalent...
Aiming at the defect of traditional risk priority number (RPN) method in FMECA, a RPN assessment method is put forward which bases on the fault propagation probability and cost, then a corrective actions choice method is presented by gray correlation theory. Firstly, the occurrence probability and cost are calculated according to fault propagation tree. RPN is assessed by the overall risk of the events...
In this work, we study the NP-hard problem of maximizing lightpath reliability in optical mesh networks against simultaneous failures of multiple fiber links. The fiber links belong to shared risk link groups (SRLGs) that have arbitrary failure probabilities. We study three heuristic algorithms and evaluate their performance through simulations.
Many fingerprint recognition systems are based on minutiae matching. However, the recognition accuracy of minutiae-based matching algorithms is highly dependent on the fingerprint minutiae quality. Therefore, in this paper, we introduce a quality integrated spectral minutiae algorithm, in which the minutiae quality information is incorporated to enhance the performance of the spectral minutiae fingerprint...
The values of distributed generator (DG) are very dependent on its location as it was installed in distribution feeders as well as its type and size. In order to enhance the reliability and obtain the benefits for DG placement, an analytical method for DG placements considering reliability improvements is proposed in this paper. The proposed method tries to solve the optimal DG placement from the...
In this paper, we report stochastic comparisons of maintenance policies for minimal repairs with the generalized age replacement. Results of comparisons of the same policy for different units with minimal repair in the hazard rate order are given.
RMS (Reliability; Maintainability; Supportability) information collecting and statistic analysis can be used to evaluate equipment's RMS level in operational condition. Also it is highly important to perfecting support concept, improving on quality and reliability growth. The paper briefly states RMS information collecting and statistic analysis method of certain electron equipment. RMS parameters...
The paper presents a technique for analyzing the dependability of programmable logic controllers (PLCs) I/O modules. The technique is based on the mode in which the I/O modules fulfill their tasks and not on their structure. Such an approach allows a unified analysis of I/O modules, regardless of their type, for almost the entire analysis work. The particularization of the I/O module type becomes...
Instant wireless sensor network (IWSN) is a type of WSN deployed for a class of special applications which have the common requirement on instantly responding for collecting and transmitting sensory data, e.g., volcanic eruption monitoring or nuclear leakage detection. In this paper, having a cluster-based WSN, we present a compensation-based reliable data delivery protocol (CRDD) to collect and transmit...
It is pointed out that the reliability of information is largely ignored and the information that is not absolutely reliable is widely existent. The significance of studying the reliability of information is explicated. The consideration of the reliability of information in Shannon information theory is analyzed, and the relation between the reliability of information and the uncertainty of information...
High density probe-based storage devices use multiple, simultaneously accessed parallel channels for achieving high I/O data rates. This paper presents an analytical methodology for evaluating the performance of coding and interleaving schemes in such devices, when they are affected by burst errors. Markov processes are used to describe the burstiness of errors due to external disturbances and analytical...
Context management systems allow services and application easy access to remote dynamic context elements, in turns allow these to adapt to the users context. The fact that most information is dynamic and changes value over time, leads to potential risk of obtaining information mismatching the true value due to the communication delay. The probability for this we call the mismatch probability. Obtaining...
