Execution patterns and fault distribution characteristics of a program will aaect the failure process and thus reliability estimates. The failure process of a software system is innuenced by many factors, and traditional software reliability engineering has found it diicult to isolate the eeect of each individual factor. A simulation approach is used to investigate the eeects of fault distribut...

nowadays, water supply for sustainable development is one of the most important concerns and challenges in most countries of the world. due to determination of groundwater potential zones are one of the important tools in the conservation, management and utilization of water resources. thus, the present study aimed to prioritize the effective factors on groundwater potential and its susceptibil...

In the fault diagnosis, the precision matching algorithm plays a very important role. The matching algorithms have been developed increasingly by considering main factors. We introduce several matching algorithms considered the combination of six essential factors. The each factor can affect the performance of the matching algorithm for fault diagnosis. The factors are applications of positive ...

Test case prioritization involves scheduling test cases in an order that increases the effectiveness in achieving some performance goals. One of the most important performance goals is the rate of fault detection. Test cases should run in an order that increases the possibility of fault detection and also that detects the most severe faults at the earliest in its testing life cycle. In this pap...

PROOFS (Parallel RestOrative Orderindependent Fault Simulator) is a hybrid of concurrent, differential, and parallel fault simulation algorithms. It retains fault dropping advantage of concurrent method, word level parallelism of parallel method and low memory requirement of differential, while minimizing their individual disadvantages. Parallel simulation of faults reduces simulation time of P...

Automobile automatic transmission is a complex system integrates machine, electricity, liquid, in terms of its fault diagnosis has the characteristics of uncertainty and high complex correlation, thus put forward the Bayesian network based on the theory of probability and theory of the fault tree for fault diagnosis methods of automobile automatic transmission, it has a certain value for applic...

Aiming at the problem of diagnosis difficulty caused by too many factors of woodworking machinery system, a kind of diagnosing method based on fault phenomenon was presented. The research on woodworking machinery system fault phenomenon space arrived at conclusion that the emergency of each fault phenomenon subject to 0-1 distribution. Therefore, phenomenon vector corresponding to each fault fo...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....
