STATEMENT OF PROBLEM Fabrication of indirect complete crowns that are in occlusal harmony upon insertion remains a problem in restorative dentistry, and dental stone cast expansion may play a role. PURPOSE This 3-part investigation compared occlusal contacts in a simulated patient with a harmonious occlusion with centric occlusion equal to maximum intercuspation (CO=MI) and an inharmonious oc...

In this paper a complete analysis of spot defects in industrial S R A M s will be presented. All possible defects are simulated, and the resulting electrical faults are transformed into functional fault models. The existence of the usually used theoretical memory fault models will be verified and new on,es will be presented. Finally, a new march test detecting all realistic faults, with a test ...

In the near future, many more navigation satellites with dual frequency L1 and L5 will be deployed. The increased number of satellites and the possibility of mitigating the ionospheric delay using dual frequency have opened the door to the possible use of RAIM for vertical guidance. For this purpose, several Advanced RAIM (ARAIM) algorithms have been proposed and extensive simulation studies ha...

In this paper we propose the first practical fault attack on the time redundancy countermeasure for AES using a biased fault model. We develop a scheme to show the effectiveness of a biased fault model in the analysis of the time redundancy countermeasure. Our attack requires only faulty ciphertexts and does not assume strong adversarial powers. We successfully demonstrate our attack on simulat...

In 2012 August 11 (12:23 UTC) a moderate earthquake with MW=6.4 (USGS) occurred between Ahar and Varzaghan towns in Azarbayjan Province at northwest of Iran. After eleven minutes another earthquake shook the area with MW=6.2 (USGS). These consecutive earthquakes followed by intensive sequences of aftershocks whereas the strongest one had MW=5.3 (USGS). In data processing including depth modific...

Near-trench slip during large megathrust earthquakes (megaquakes) is an important factor in the generation of destructive tsunamis. We proposed a new approach to assessing the near-trench slip potential quantitatively by integrating laboratory-derived properties of fault materials and simulations of fault weakening and rupture propagation. Although the permeability of the sandy Nankai Trough ma...

This paper presents a novel approach for fault location in distribution system using neural network. The voltage and current in the instance of fault are used for training. Different faults are simulated in a specific feeder by PSCAD software. The MATLAB and EMTDC are used for simulation in this work. The results of case studies show the capability of neural networks in fault location with negl...

S U M M A R Y We investigate the seismic velocity contrast across the San Andreas fault (SAF) in the Parkfield area using fault zone head waves (FZHW) that propagate along the bimaterial fault interface and direct P waves. We systematically analyse large data sets of near-fault waveforms recorded by several seismic networks over the period 1984–2005. Clear FZHW are observed at many stations on ...

This paper proposes a novel fault-propagation pattern based differential fault analysis method FPP-DFA, and proves its feasibility on SPN structure block ciphers using bitwise permutation, such as PRESENT and PRINTcipher. Simulated experiments demonstrate that, with the fault model of injecting one nibble fault into the r-2 round substitution layer, on average 8 and 16 faulty samples can reduce...

current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. application of the intelligent system for fault direction classification has been suggested in this paper. a new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. the proposed classifier uses ...
