1081   Fault detection and diagnosis in the DAMADICS benchmark actuator system a hidden Markov model app Fault detection and diagnosis in the DAMADICS benchmark actuator system a hidden Markov model app    2008 Early fault detection and diagnosis in chemical process monitoring represents a challenge to be overcome. Another one concerns the spatial overlapping problem among distinct fault classes, once some events may only be distinguished from the others by taking into account its order of occurrence. The hidden Markov model (HMM) technique is capable of providing information about the tendency of the process and of modelling ordered data. Hence, the goal is to investigate the contribution of this tech... 查看全文

1083   Economic evaluation of benefits associated with automated fault detection and diagnosis in rooftop air conditioners Economic evaluation of benefits associated with automated fault detection and diagnosis in rooftop air conditioners    2007 In contrast to critical systems, one of the primary consequences of faults in HVAC&R systems is economic rather than safety related. Therefore, fault detection and diagnosis (FDD) systems applied to HVACsystems should be assessed based on economic considerations. However, existing FDD research in HVAC applications has mainly focused on technique development and validation. This paper addresses the economics of FDD application to rooftop air-conditioning units (RTUs). Two major aspects of sav... 查看全文

Verwys;Todd A. Kahan    1998 In a lexical decision task with two primes and a target, the target was preceded 300 msec by the second prime (P2) which in turn was preceded by a brief forward and backward masked first prime (P1). When P1 and P2 were unrelated, reaction times were faster when the target was related to P2 (e.g.,wave SALT ... pepper) than when the target was unrelated to P2 (and P1—e.g.,wave LOAN ... pepper). However, this semantic priming effect was reduced to statistically nonsignif... 查看全文

1089   PeerWatch: A fault detection and diagnosis tool for virtualized consolidation systems PeerWatch: A fault detection and diagnosis tool for virtualized consolidation systems    2010 Server virtualization is now becoming an effective means to consolidate numerous applications into a small number of machines. While such a strategy can lead to significant savings in power and hardware cost, it may complicate the fault management task due to the increasing scalability and complexity in the virtualized environment. In this paper, we propose PeerWatch, a fault detection and diagnosis tool specially designed for virtualized consolidation systems. Based on the observation that each... 查看全文

1090   Novel method of early fault detection and diagnosis for technical process Novel method of early fault detection and diagnosis for technical process    2000 Based on the analysis of characteristics of two classes of technical process fault and defects of two familiar fault detection and diagnosis methods, an early fault detection and diagnosis method for technical process was presented. Taking advantage of quantitative redundant relationship of some dependent variables or symptoms in the process system after fault happening, the method can avoid the lag in familiar fault detection and diagnosis methods by using the dynamic trend information of the v... 查看全文

1091   Actuator fault diagnosis using High-Order Sliding Mode Differentiator (HOSMD) and its application to Actuator fault diagnosis using High-Order Sliding Mode Differentiator (HOSMD) and its application to    2008 Actuator fault diagnosis problem is studied for a class of nonlinear systems with relative degrees from the inputs to the outputs higher than one. This type of nonlinear systems include many mechanical systems, and their actuator fault diagnosis problem can be very challenging because of nonlinearities and high relative degrees. In this paper, in order to solve the actuator fault diagnosis problem for the considered nonlinear systems, 2nd-order and 3rdorder sliding mode differentiators are used ... 查看全文

1092   Comparison between power line communication multipath model and coaxial cable interferometer theory Comparison between power line communication multipath model and coaxial cable interferometer theory L. B. McCusker, R. B. Von Dreele, D. E. Cox, D. Loueuml;r and P. Scardi    2012 The authors have studied a new method to find parameters of broadband power line communication channel model. Lossless power line communication channel model is compared with classical interferometers approach to develop this model. The authors also used coaxial cables to simulate a multipath channel, because it can behave like a lossless power line communication channel. Thus, measurements were carried out with a network analyzer to find S parameters. The modeling parameters, for the multipath ... 查看全文

When the vehicle surface is damaged, the change of aerodynamic parameters follows a rule, i.e., the difference between the normal aerodynamic parameter vector and the fault aerodynamic parameter vector is proportional to the normal vector, and the proportion coefficient is the failure rate of surface damage. Based on the aerodynamic structure o... 查看全文

The effect of SiO2 content on mechanical and solvent-resistant properties of PU/SiO2 composites was investigated. It was found that with increasing SiO2 content, the tensile strength and toughness, hardness, and modulus of PU composites increased. PU/SiO2 composites exhibited only one loss peak corresponding to the glass transition temperature of the soft-segment of PU, which shif... 查看全文

Gerzeski    2012 Novel poly(3-hydroxyoctanoate), P(3HO), and bacterial cellulose composites have been developed. P(3HO) is hydrophobic in nature whereas bacterial cellulose is extremely hydrophilic in nature. Therefore, homogenized bacterial cellulose has been chemically modified in order to achieve compatibility with the P(3HO) matrix. Modified bacterial cellulose microcrystals and P(3HO) have been physically blended and solvent casted into two-dimensional composite films. Mechanical characterization shows that... 查看全文

The influence of the number of detectors is obtained by comparing a given size distribution and a calculated size distribution by computer simulation and experimental method. An observing range of scattering angles is from 0.0007 to 2.5 rad. A non-linear iteration method is used for calculating particle size distribution. The number of ... 查看全文

1099   Operation point dependent diagnosis - Wait Operation point dependent diagnosis - Wait    2009 As fault detection is becoming increasingly relevant for modern passenger car Diesel engines, it is now time to take a closer look at the engine specific fault diagnosis problems. Many of the applied fault detection algorithms can only be computed in certain operation ranges of the engine. Whenever the engine is operated outside these ranges, the corresponding symptoms are usually not actualized. As a matter of course this has to be considered in the design of a diagnosis system. However, since ... 查看全文

Most of the existing work focuses on verifying the expected behavior. in the original model, i.e. positive testing. In this paper negative testing is introduced to check the unexpected behavior. Mutants are divided into three types: increscent, decrescent, and cross mutants. Both, positive and negative testing is proposed to guarantee the detection of... 查看全文

For this purpose, test data are represented by several scales on time-scale plane using the CWT and then the information is combined to reconstruct the original data. However, this reconstructed signal is a redundant signal and it reflects some different information from the test data. Therefore, this redundant information can be... 查看全文
