As software systems mature, there is the danger that not only code decays, but software architecture as well. We adapt a reverse architecting technique to defect reports of a series of releases. Relationships among system components are identified based on whether they are involved in the same defect report, and for how many defect reports this occurs. There are degrees of fault-coupling betwee...

|This paper is an attempt to understand the processes by which software ages. We de ne code to be aged or decayed if its structure makes it unnecessarily di cult to understand or change, and we measure the extent of decay by counting the number of faults in code in a period of time. Using change management data from a very large, long-lived software system, we explore the extent to which measur...

Based on ServiceBSP model, a hierarchical resource load balancing algorithm with Multi-Agent is put forward in this paper which achieves the goal of dynamic load balancing and favorable Fault-tolerant. The algorithm calculates the load value according to the attributes of resource and scheduling tasks relies on the load value, while updating the load information dynamically depending on Multi-A...

in the urumieh-dokhtar volcanic zone, there are nearly parallel faults to the zagros zone.they were formed during collision of the arabic plate with central iran plate. the northwest-southeast trending of qom-zefreh fault system has long been recognized as major faults in central iran. the general aim of this research is to identify the activity period of this fault and the extent of its effect...

To improve safety, reliability, and efficiency of automotive vehicles and other technical applications, embedded systems commonly use fault diagnosis consisting of fault detection and isolation. Since many systems are constructed as distributed embedded systems including multiple control units, it is necessary to perform global fault isolation using for example a central unit. However, the draw...

In this paper, TOPAS1 a new parallel programming environment for distributed systems is presented. TOPAS automatically analyzes data dependence among tasks and synchronizes data, which reduces the time needed for parallel program developments. TOPAS also provides supports for scheduling, dynamic load balancing and fault tolerance. Experiments show simplicity and efficiency of parallel programmi...

crime is a human behavior that has captivated the thoughts of scholars of various disciplines throughout history. philosophers, sociologists, psychologists and others have investigated and analyzed the concept of crime from different aspects. crime is the main topic of criminal law, and in its legal meaning is a well-known term with a certain conceptual load that should not be confused with sim...

Software-implemented fault injection is a powerful strategy to test fault-tolerant protocols in distributed environments. In this paper, we present ComFIRM, a communication fault injection tool we developed which minimizes the probe effect on the tested protocols. ComFIRM explores the possibility to insert code directly inside the Linux kernel in the lowest level of the protocol stack through t...

This paper presents a new approach for the protection of Thyristor-Controlled Series Compensator (TCSC) line using Support Vector Machine (SVM). One SVM is trained for fault classification and another for section identification. This method use three phase current measurement that results in better speed and accuracy than other SVM based methods which used single phase current measurement. This...

Themain challengein wireless sensor network is to improve the fault tolerance of each node and also provide an energy efficient fast data routing service. In this paper we propose an energyefficient node fault diagnosis and recovery for wireless sensor networks referred as fault tolerant multipath routing scheme for energy efficientwireless sensor network (FTMRS).The FTMRSis based on multipath ...
