The aim of the research is to investigate techniques that support the development of highly dependable applications in a distributed system environment. Techniques we developed include redundant task allocation, load balancing, fault-tolerant computing and communication. The application we have implemented in the system is a firewall application. The firewall runs in redundant mode. Each incomi...

Implementation of electronic prescribing system can overcome many problems of the paper prescribing system, and provide numerous opportunities of more effective and advantageous prescribing. Successful implementation of such a system requires complete and deep understanding of work content, human force, and workflow of paper prescribing. The current study was designed in order to model the curr...

Resilience, the ability to withstand disruptions and recover quickly, must be considered during system design because any disruption of the system may cause considerable loss, including economic and societal. This work develops analytic maximum flow-based resilience models for series and parallel systems using Zobel's resilience measure. The two analytic models can be used to evaluate quantitat...

Redundant actuated parallel robot is a multi-input and multi-output (MIMO) system which usually works in an uncertain environment. In this paper, the force/position hybrid control structure of 6PUS-UPU redundant actuation parallel robot is designed, proportional-integral (PI) and model predictive control (MPC) cascade control strategy are used in the redundant branch of 6PUS-UPU redundant actua...

In the past few decades, the significant developments in database and networking technologies contributed to advances in distributed database systems (DDS). The data allocation is a prominent issue in distributed database systems and is performed on data access static and dynamic patterns. This paper proposes a new strategy named Extended Threshold Algorithm (ETA) for non-redundant dynamic data...
