Replicated systems are a kind of distributed systems whose main goal is to ensure that computer systems are highly available, fault tolerant and provide high performance. One of the last trends in replication techniques managed ...

[ES] Durante estos últimos años, el desarrollo tecnológico ha propiciado un aumento en las prestaciones de los sistemas digitales, pero a costa de reducir su confiabilidad. Por ejemplo, y gracias a la continua reducción ...

[ES] El presente trabajo consiste en el diseño y puesta en marcha del sistema de guiado de un robot móvil basado en visión artificial y sensores de distancia ultrasónicos que presentará capacidades básicas de tolerancia ...

This video shows the basics of the dynamic hardware redundancy and how it works.

[EN] Near Threshold Voltage (NTV) computing has been recently proposed as a technique to save energy, at the cost of incurring higher error rates including, among others, Silent Data Corruption (SDC). In this paper, we ...

This video describe briefly the types of hardware redundancy, and shows the behaviour of a TMR system with spare.

Dependability benchmarks are aimed at comparing and selecting alternatives in application domains where faulty conditions are present. However, despite its importance and intrinsic complexity, a rigorous decision process ...

When one joint of a manipulator fails and is locked, the velocities of remaining joints will produce sudden change. The sudden change of joint velocity in fault tolerant operation of two coordinating manipulators for locked ...

[EN] This paper presents a fault-tolerant algorithm ensuring multiple resources sharing in mobile ad hoc networks (MANETs) that is able to handle the known K-mutual exclusion problem in such mobile environments. The proposed ...

[EN] Due to transistor shrinking, intermittent faults are a major concern in current digital systems. This work presents an adaptive fault tolerance mechanism based on error correction codes (ECC), able to modify its ...
