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....

Based on conventional approaches for the integration of resistive-type superconducting fault current limiters (SFCLs) on electric distribution networks, SFCL models largely rely on the insertion of a step or exponential resistance that is determined by a predefined quenching time. In this paper, we expand the scope of the aforementioned models by considering the actual behaviour of an SFCL in t...

Self-stabilizing systems can automatically recover from arbitrary transient faults, and changes in the environment of the system, without any external intervention. However, in existing distributed self-stabilizing protocols, the performance of recovery is not linked to the severity of the fault. Recovery from failure at even a single component of the system may take a long time and aaect the o...

We thank Art Frankel for his continuing interest in unraveling the details of the complicated source process of the 1987 Superstition Hills earthquake. His insightful comments and subsequent modeling on our part has helped to resolve some of the differences between the rupture model presented in Wald et al. (1990), hereafter referred to as WEA, and that published by Frankel and Wennerberg (1989...

We derive a Kalman filter based on data from a sliding window. This is used for a new approach to fault detection and diagnosis, where the state estimate from past data is compared to the state estimate of some of the future data. We suggest a method to judge the quality of diagnosis in a simple way. For fault estimation in the diagnosis, the general concept of stochastic observability in linea...

We complete the study of [16] and [20] about the Miller’s algorithm. The Miller’s algorithm is a central step to compute the Weil, Tate and Ate pairings. The aim of this article is to analyse the weakness of the Miller’s algorithm when it undergoes a fault attack. We prove that the Miller’s algorithm is vulnerable to a fault attack which is valid in all coordinate systems, through the resolutio...

When designing model-based fault-diagnosis systems, the use of consistency relations (also called e.g. parity relations) is a common choice. Different subsets are sensitive to different subsets of faults, and thereby isolation can be achieved. This paper presents an algorithm for finding a small set of submodels that can be used to derive consistency relations with highest possible diagnosis ca...

The paper provides a literature review of the STEPNC compliant research around the world. The first part of this paper focuses on projects based on STEP compliance followed by research and development in this area based on machining operations. Review the literature relating to relevant STEP standards and application in the area of turning centers. This research will review the various research...

We examine corresponding Cauchy-Riemann equations by using the non-commutativity for the product on split-biquaternions. Additionally, we describe the regularity of functions and properties of their differential equations on split-biquaternions. We investigate representations and calculations of the derivatives of functions of split-biquaternionic variables. c ©2016 all rights reserved.
