As a typical example of large and complex mechanical systems, rotating machinery is prone to diversified sorts of mechanical faults. Among these faults, one of the prominent causes of malfunction is generated in gear transmission chains. Although they can be collected via vibration signals, the fault signatures are always submerged in overwhelming interfering contents. Therefore, identifying th...

A probabilistic event-driven fault localization technique is presented, which uses a symptom-fault map as a fault propagation model. The technique isolates the most probable set of faults through incremental updating of the symptom explanation hypothesis. At any time, it provides a set of alternative hypotheses, each of which is a complete explanation of the set of symptoms observed thus far. T...

The reliable execution of mobile agents is a very important design issue in building mobile agent systems and many fault-tolerant schemes have been proposed so far. Security is a major problem of mobile agent systems, especially when monetary transactions are concerned. Security for the partners involved is handled by encryption methods based on a public key authentication mechanism and by secr...

Fault localization is one of the most difficult activities in software debugging. Many existing statistical faultlocalization techniques estimate the fault positions of programs by comparing the program feature spectra between passed runs and failed runs. Some existing approaches develop estimation formulas based on mean values of the underlying program feature spectra and their distributions a...

Other work has shown that adaptive learning can be highly successful in developing programs which are able to play games at a level similar to human players and, in some cases, exceed the ability of a vast majority of human players. This study uses poker to investigate how adaptation can be used in games of imperfect information. An internal learning value is manipulated which allows a poker pl...

Players of complex board games like backgammon, chess and go, were always wondering what the best opening moves for their favourite game are. In the last decade, computer analysis has offered more insight to many opening variations. This is especially true for backgammon, where computer rollouts have radically changed the way human experts play the opening. In this paper we use Palamedes, the w...

The reliable execution of a mobile agent is a very important design issue in building a mobile agent system and many fault-tolerant schemes have been proposed so far. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. For this purpose, we first identify two basic requirements for fault-tolerant mobile agent execution:...

This draft proposes a generic routing method and protocol for a regular data center network, named as the fault-avoidance routing (FAR) protocol. FAR protocol provides a generic routing method for all types of network architectures that are proposed for large-scale cloud-based data centers over the past few years. FAR protocol is well designed to fully leverage the regularity in the topology an...

11 Earthquakes can rupture geometrically complex fault systems by breaching fault step-overs. 12 Quantifying the likelihood of rupture jump across step-overs is important to evaluate earth13 quake hazard and to understand the interactions between dynamic rupture and fault growth 14 processes. Here we investigate the role of seismogenic depth and background stress on phys15 ical limits of earthq...

Three different degrees of heterogeneous fault models are simulated by using 2-D random dynamic cellular automata models for analyzing macroscopic behaviors of seismic activity evolution influenced by heterogeneity of fault structures. The results show that the heterogeneities of fault structures can influence evolution properties of the foreshock activity and rupture process, such as the media...
