ALLIANCE: An Architecture for Fault Tolerant Multi-Robot Cooperation

by Lynne E. Parker - IEEE Transactions on Robotics and Automation , 1998
"... ALLIANCE is a software architecture that fa- cilitates the fault tolerant cooperative control of teams of heterogeneous mobile robots performing missions composed of loosely coupled subtasks that may have ordering dependencies. ALLIANCE allows teams of robots, each of which possesses a variety of hi ..."

Implementing Fault-Tolerant Services Using the State Machine Approach: A Tutorial

by Fred B. Schneider - ACM COMPUTING SURVEYS , 1990
"... The state machine approach is a general method for implementing fault-tolerant services in distributed systems. This paper reviews the approach and describes protocols for two different failure models--Byzantine and fail-stop. System reconfiguration techniques for removing faulty components and i ..."

Basic concepts and taxonomy of dependable and secure computing

by Algirdas Avizienis, Jean-claude Laprie, Brian Randell, Carl Landwehr - IEEE TDSC , 2004
"... This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, integrity, maintainability, etc. Security brings in concerns for confidentiality, in addition to availability and integrity. Basic defin ..."

definitions are given first. They are then commented upon, and supplemented by additional definitions, which address the threats to dependability and security (faults, errors, failures), their attributes, and the means for their achievement (fault prevention, fault tolerance, fault removal, fault forecasting

A survey of outlier detection methodologies

by Victoria J. Hodge, Jim Austin - Artificial Intelligence Review , 2004
"... Abstract. Outlier detection has been used for centuries to detect and, where appropriate, remove anomalous observations from data. Outliers arise due to mechanical faults, changes in system behaviour, fraudulent behaviour, human error, instrument error or simply through natural deviations in populat ..."

A line in the sand: a wireless sensor network for target detection, classification, and tracking

by A. Arora , P. Dutta , S. Bapat , V. Kulathumani , H. Zhang , V. Naik, V. Mittal , H. Cao , M. Demirbas , M. Gouda , Y. Choi , T. Herman , et al. - COMPUTER NETWORKS , 2004
"... Intrusion detection is a surveillance problem of practical import that is well suited to wireless sensor networks. In this paper, we study the application of sensor networks to the intrusion detection problem and the related problems of classifying and tracking targets. Our approach is based on a de ..."

Slipstream processors: improving both performance and fault tolerance

by Karthik Sundaramoorthy, Zach Purser, Eric Rotenberg - In Proceedings of the ninth international conference on Architectural
"... Processors execute the full dynamic instruction stream to arrive at the final output of a program, yet there exist shorter instruction streams that produce the same overall effect. We propose creating a shorter but otherwise equivalent version of the original program by removing ineffectual computat ..."

Comparing Detection Methods For Software Requirements Inspections: A Replicated Experiment

by Adam A. Porter, Lawrence G. Votta, Jr., Jr. Victor, Victor R. Basili , 1995
"... Software requirements specifications (SRS) are often validated manually. One such process is inspection, in which several reviewers independently analyze all or part of the specification and search for faults. These faults are then collected at a meeting of the reviewers and author(s). Usually, revi ..."

, reviewers use Ad Hoc or Checklist methods to uncover faults. These methods force all reviewers to rely on nonsystematic techniques to search for a wide variety of faults. We hypothesize that a Scenario-based method, in which each reviewer uses different, systematic techniques to search for different

Analysis of software fault removal policies using a non-homogeneous continuous time markov

by Swapna S. Gokhale
"... Abstract. Software reliability is an important metric that quantifies the quality of a software product and is inversely related to the residual number of faults in the system. Fault removal is a critical process in achieving desired level of quality before software deployment in the field. Conventi ..."

to compute the failure intensity of the software in the presence of explicit fault removal is also proposed. The fault removal scenarios can be easily incorporated using the state-space view of the non-homogeneous Poisson process.

Undulator Hall Air Temperature Fault Scenarios ∗

by J. Sevilla, J. Welch , 2008
"... Recent experience indicates that the LCLS undula-tor segments must not, at any time following tun-ing, be allowed to change temperature by more than about ±2.5 C or the magnetic center will irreversibly shift outside of acceptable tolerances. This vulnera-bility raises a concern that under fault con ..."

conditions the ambient temperature in the Unduator Hall might go outside of the safe range and potentially could require removal and retuning of all the segments. In this note we estimate changes that can be ex-pected in the Undulator Hall air temperature for three fault scenarios: 1. System-wide power

The Scenario

by Franco Zambonelli
"... It was a pleasant, warm, evening. Franco walked slowly inside the park, found a nice area of soft grass, and sat down. Got a packed ball of spaghetti out of his left pocket, and an open beer out of the right. He ate and drunk, and rested quietly in front of a wonderful and clean spring sunset, rare ..."
