Hardening of Smart Electronic Lock Software against Random and Deliberate Faults

2020 23rd Euromicro Conference on Digital System Design (DSD), 2020
In this research paper, analysis of smart electronic lock behavior during presence of faults in its controller is examined. A typical smart electronic lock is composed of a controller unit, usually implemented in a processor, and the mechanical part, which may be for example a stepper motor.

Point defects and lock-in faults in columnar phases

Liquid Crystals, 1990
Abstract We show the existence of point defects connected by strings in columnar phases. The most interesting consequence is the increase, by several orders of magnitudes, of the bend elastic modulus as compared to values for nematics.

A Physical Model for Interseismic Erosion of Locked Fault Asperities

Journal of Geophysical Research: Solid Earth, 2017
Abstract The conventional “asperity model” posits that faults are partitioned into fixed velocity‐weakening (VW) patches (asperities) that are locked interseismically and velocity‐strengthening (VS) regions that creep stably without accumulating stress.

Kinematic Constraints on Fault-Tolerant Gaits for a Locked Joint Failure

Journal of Intelligent and Robotic Systems, 2006
Fault-tolerant gaits in legged locomotion are defined as gaits with which legged robots can continue their walking after a failure event has occurred to a leg of the robot. For planning an efficient fault-tolerant gait, kinematic constraints and remaining mobility of the failed leg should be closely examined with each other.

A Reconfiguration-Based Fault-Tolerant Anti-Lock Brake-by-Wire System

ACM Transactions on Embedded Computing Systems, 2018
Anti-Lock Braking Systems (ABS) and Brake-by-Wire Systems (BBW) are safety-critical applications by nature. Such systems are required to demonstrate high degrees of dependability. Fault-tolerance is the primary means to achieve dependability at runtime and has been an active research area for decades.

Structural fault diagnosis in charge-pump based phase-locked loops

18th International Conference on VLSI Design held jointly with 4th International Conference on Embedded Systems Design, 2005
An approach is presented for identifying structural-faults, using the charge-frequency based built-in-self test (CF-BIST) technique in a phase-locked loop (PLL) circuit, for a standard 0.18 /spl mu/m CMOS process. This method not only validated the CF-BIST approach for fault detection, but also showed an algorithm for how this approach may possibly be ...

Fault-tolerant synchronization using phase-locked clocks

Microelectronics Reliability, 1990
Abstract Real-time computer systems are increasingly being used in the control of life-critical processes such as aircraft. Such computers are generally multiprocessors. It is very important to be able to tightly and reliabily synchronize the various processors.

Soil gas CO2 emissions and fault locking along the Anninghe fault and the Zemuhe fault, in China Seismic Experimental Site

2020
<p>The Anninghe fault (ANHF) and the Zemuhe fault (ZMHF) with high level of seismic hazards in the China Seismic Experimental Site, located in southeastern of Tibet, are some of the most active faults in China. Measurement of the soil gas CO<sub>2</sub> has been conducted in three sites along the ANHF ...

Imaging the Electrical Resistivity Structure of a Locked Fault Segment: The Ganos Fault example

The Ganos Fault, in the westernmost part of the North Anatolian Fault Zone (NAFZ), stayed quiet for approximately 146 years before two catastrophic events shook the area in the summer of 1912. The historical records point out that two devastating activities shook both sides of the Marmara Sea in 1766, too. Following the 1766 events, on August 9th, 1912,
