considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...

the idea of this paper is designing an automatic fault detection system based on fuzzy logic, therefore two signals of pmsm in fault condition are analyzed for inter turn fault detection: current and torque. in this fault type there is some distortion in these signals, but it is not good enough to detecting with fuzzy logic solely, so with combination of wavelet transform and fcm a new method f...

the concept of fault, like other social phenomena, is always changing, following the variable justice. the economic, moral, and philosophical consideration, are the most influential factors in the process of change. however, it seems that, apart from exceptional issues of revolutionary changes, the economic and material factors lead the way. in this historical process, the definitions of fault ...

GridFTP is the de facto standard for providing secure, robust, highspeed bulk data transport. It is based on the Internet FTP protocol, and it defines extensions for high performance operation and security. However, GridFTP lacks an easy-to-use graphical user interface client that is fault tolerant and hides all the complexities from the end users. It is not straightforward to conduct data tran...

Large magnitude (Mw ∼ ≥6) earthquakes in extensional settings are often associated with simultaneous rupture of multiple normal faults as a result static and/or dynamic stress transfer. Here, we report details the coseismic breaching previously unrecognized large-scale fault relay zone central Greece, through three successive moderate 5.7–6.3) that occurred over period ∼10 days March 2021. Spec...

In the paper, a communication infrastructure for faulttolerant embedded control system is discussed. It was developed as a part of experimental platform of the IFATIS project within the 5th European Union framework programme, dealing with dependable, reconfigurable integrated control systems. In such environments, a reliable and robust physical interconnection is required. The communication is ...

This paper describes the conceptual model for, and the implementation of, a software fault-tolerance layer (FT-layer) for distributed fault-tolerant hard realtime systems. This FT-layer provides error detection capabilities, fault-tolerance mechanisms based on active replication, and the interface between the application software running on a node of the distributed system and the communication...

Service-oriented architecture provides interoperability and weak coupling features for software development. Representational state transfer (REST) is an architectural style that has attracted attention in the SOA domain as it allows the development of Web services based on original principles of the World Wide Web. Unlike Web service specifications, which are based on Simple Object Access Prot...

A Mobile Agent (MA) is autonomous and identifiable software process that travel through a network of heterogeneous machine and act autonomously on behalf of user. Improving the survivability of MA in presence of various faults is the major issue concerns with implementation of MA. This paper presents a brief introduction of Hierarchical Fault Tolerance Protocol (HFTP) for Mobile Agents, which c...
