Shadow Replication: An Energy-Aware, Fault-Tolerant Computational Model for Green Cloud Computing

Cui, Xiaolong; Mills, Bryan; Znati, Taieb; Melhem, Rami - In: Energies 7 (2014) 8, pp. 5151-5176

As the demand for cloud computing continues to increase, cloud service providers face the daunting challenge to meet the negotiated SLA agreement, in terms of reliability and timely performance, while achieving cost-effectiveness. This challenge is increasingly compounded by the increasing...

Quorums Systems as a Method to Enhance Collaboration for Achieving Fault Tolerance in Distributed System

PETRI, Ioan - In: Informatica Economica 13 (2009) 2, pp. 68-75

A system that implements the byzantine agreement algorithm is supposed to be very reliable and robust because of its fault tolerating feature. For very realistic environments, byzantine agreement protocols becomes inadequate, because they are based on the assumption that failures are controlled...

Optimal current waveforms for torque control of permanent magnet synchronous machines with any number of phases in open circuit

Baudart, F.; Matagne, E.; Dehez, B.; Labrique, F. - In: Mathematics and Computers in Simulation (MATCOM) 90 (2013) C, pp. 1-14

Polyphase permanent magnet synchronous motors are well suited for electromechanical actuation systems demanding a high level of reliability. They are indeed able to run on a reduced number of phases and therefore to make the actuation system fault tolerant. The paper introduces a Lagrangian...

Clustering genome data based on approximate matching

Patil, Nagamma; Toshniwal, Durga; Garg, Kumkum - In: International Journal of Data Analysis Techniques and … 5 (2013) 2, pp. 122-147

Genome data mining and knowledge extraction is an important problem in bioinformatics. Some research work has been done for genome identification based on exact matching of n-grams. However, in most real world biological problems, it may not be feasible to have an exact match, so approximate...

Fault tolerance in large games

Gradwohl, Ronen; Reingold, Omer - In: Games and Economic Behavior 86 (2014) C, pp. 438-457

A Nash equilibrium is an optimal strategy for each player under the assumption that others play according to their respective Nash strategies, but it provides no guarantees in the presence of irrational players or coalitions of colluding players. In fact, no such guarantees exist in general....

Simulation-based optimization of an agent-based simulation

Deckert, Andreas; Klein, Robert - In: Netnomics 15 (2014) 1, pp. 33-56

Optimization of an agent-based simulation (ABS) bears specific challenges. It is demonstrated in this paper that … mainstream simulation-based optimization (SBO) approaches often do not perform well in such a setting, sometimes hardly … neglected so far, but should structurally also be universally applicable for other simulation-based optimization problems as …

Non-fully invested derivative-free bond index replication

Markov, Iliya; Oeuvray, Rodrigue; Tuchschmid, Nils - In: Financial Markets and Portfolio Management 27 (2013) 1, pp. 101-124

The problem we address here is the replication of a bond benchmark when only a fraction of the portfolio is invested for the replication. Our methodology is based on a minimization of the tracking error subject to a set of constraints, namely (1) the fraction invested for the replication, (2) a...
