This paper proposes the development of a scheme for fault diagnosis actuators simulated model accurately representing behaviour an autonomous underwater vehicle. The Fossen usually adopted to describe dynamics vehicle has been generalised in this take into account time-varying sea currents. proposed detection and isolation strategy uses data-driven approach relying on multi-layer perceptron neu...

Abstract The access of a high proportion renewable energy and the large-scale application open sharing communication network are two main characteristics modern interconnected power grid. However, tight coupling between cyber physical subsystem makes malicious attack sudden failure more likely to cause collapse Therefore, reverse behavior reconstruction strategy is proposed, which does not need...

Redundant Array of Inexpensive Disks (RAID) is the standard for large scale, fault-tolerant storage solutions. The various RAID levels combine space and/or performance optimization to meet the needs of the user. In the paper we introduce UPGRAID, which can be seen as a new RAID level built upon RAID5. The idea behind UPGRAID is that, by allocating a small amount of disk space for RAID stripe re...

This paper considers the problem of robust reconstruction of simultaneous actuator and sensor faults for a class of uncertain Takagi–Sugeno nonlinear systems with unmeasurable premise variables. The proposed fault reconstruction and estimation design method with H∞ performance is used to reconstruct both actuator and sensor faults when the latter are transformed into pseudo-actuator faults by i...

Diagnosis method based on Principal Component Analysis (PCA) has been widely developed. However, this method deals only with data which are described by single-valued variables. The purpose of the present paper is to generalize the diagnosis method to interval PCA. The fault detection is performed using the new indicator [SPE]. To identify the faulty variables, this work proposes a new method b...

Image super-resolution algorithm improves image resolution in software. Before image tracking, it needs to enhance image resolution to improve the image tracking accuracy of the bionic eye. The traditional super-resolution reconstruction method can’t satisfy the accuracy and real-time system, so this paper proposes super-resolution image reconstruction algorithm based on SURF (Speeded up Robust...

This paper deals with currently used algorithms for the reconstruction of functional images which run up to 60 hours or more on a single workstation and deal with hundreds of megabyte of data. A parallel implementation with high eeciency and almost linear speedup of a sophisticated iterative algorithm is given and its applicability to other reconstruction methods is shown. Whereas running this ...

The power supply and distribution network of prosumer group is equipped with contact switch section switch. After feeder fault occurs, the topological structure can be adjusted by changing state each in system, so as to realize reconstruction after fault, restore free area. optimal configuration different types switchgear appropriate position reduce time location isolation, further reconfigurat...
