Model identification is an important and complicated step within the autoregressive integrated moving average (ARIMA) methodology framework. This step is especially difficult for integrated series. In this article first investigate Box-Jenkins methodology and its faults in detecting model, and hence have discussed the problem of outliers in time series. By using this optimization method, we wil...

Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

Differential Fault Analysis (DFA) finds the key of a block cipher using differential information between correct and faulty ciphertexts obtained by inducing faults during the computation of ciphertexts. Among many ciphers AES has been the main target of DFA due to its popularity. DFA of AES has also been diversified into several directions: reducing the required number of faults, applying it to...

to s top faults. "preventable" animal-caused Wildlife managers have long been concerned with the damage wildlife can cause, especially to agricultural crops. However, one area which has received little research is the damage caused by wildlife to electric substations. Such research is needed because damage to electric substations increases operating costs of utilities and reduces reliability of...

Kuhbanan fault system, as one of the intracontinental faults of central Iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. According to the geometric and kinematics data, Kuhbanan fault has been divided into 5 segments (S26, S27, S28, S29, S30) in Bahabad region. Measured geomorphic indices of ratio of v...

Hardware duplication techniques are widely used for concurrent error detection in dependable systems to ensure high availability and data integrity. These techniques are vulnerable to common-mode failures (CMFs). Use of duplex systems with diverse implementations of the two modules has been proposed in the past for protection against CMFs. In this paper, we define a category of faults, called n...

Abstract. For many countries, the methodology for offshore geohazard mitigation lags far behind well-established onshore methodology. Particularly complicated is assessment of fault hazard in marine environment. The determination whether a active or not requires ultra-high-resolution seismic surveys and multiple coring and, unfortunately, frequently ends with uncertain results. Moreover, if pip...

Immiscible displacement of one fluid by another fluid in porous media has important applications in a wide range of different technologies. Most often mentioned is hydrology and and oil recovery. From a theoretical point of view, the displacement process is very complex and hard to describe in detail. Especially, much attention has been paid to the rich variety of displacement structures that i...
