This paper proposes a new fault detection and analysis approach which can leverage incomplete prior information. Conventional data-driven approaches suffer from the problem of overfitting and result in high rates of false positives, and model-driven approaches suffer from a lack of specific information about complex systems. We overcome these problems by modifying the denoising autoencoder (DA)...

This paper presents a method to increase the reliability of UAV sensor fault detection in a multiUAV context. The method uses additional position estimations that augment individual UAV fault detection system. These additional estimations are obtained using images from the same planar scene taken from two different UAVs. Since accuracy and noise level of the estimation depends on several factor...

A GTB [1] to fibre optic interface "GTBLWL" has been developed for the FOPI RPC detector control and readout and is usable for other GTB data transmissions. The main motivation for this development was galvanic separation of the detectors from readout and trigger electronics to reduce the noise level at the detector. Another advantage of optical data transmission is insensitivity to external in...

Fault diagnosis in the presence of noise and model errors is of fundamental importance. In the paper, the meaning of fault isolation performance is formalized by using the established notion of coverage and false coverage from the field of statistics. Then formal relations describing the relationship between fault isolation performance and the residual related design parameters are derived. For...

The Qualitative Modelling and Interpretation (QMi) system translates noisy sensor data into a qualitative description of the underlying behaviorof a chemical plant and uses this information together with qualitative models to identify faults and operating regimes. Qualitative models of normal and faulty equipment are simulated to describe the range of possible behaviors in a chemical plant with...

Reliability of any model-based failure detection and isolation (FDI) method depends on the amount of uncertainty in a system model. Recently, it has been shown that the use of joint torque sensing results in a simplified manipulator model that excludes hardly identifiable link dynamics and other nonlinearities such as friction, backlash, and flexibilities. In this paper, we show that the applic...

A Faraday cage structure using through-substrate vias is an effective strategy to suppress substrate crosstalk, particularly at high frequencies. Faraday cages can reduce substrate noise by 32 dB at 10 GHz, and 26 dB at 50 GHz. We have developed lumped-element, equivalent circuit models of the Faraday cages and test structures to better understand the performance of the Faraday cages. These mod...
