چکیده

This paper addresses the design of storage systems for operation under critical environmental conditions. For these applications, these systems should have low latency time in access, high performance in throughput and high storage capabilities; therefore, they must be assembled using highly reliable components, while allowing flexibility in design. Commercial Off The Shelf (COTS) components have often been used. A COTS-based architecture is analyzed in this paper; the proposed architecture uses design-level techniques (such as error detection/correction codes and scrubbing) to make commercially available Dynamic Random Access Memory (DRAM) chips tolerant to faults. This paper provides a complete and novel analysis of engineering alternatives which arise in the design of a highly reliable memory system based on Reed Solomon coding. A comparative analysis of methods for permanent fault detection is provided; moreover using a Markovian characterization, different functional arrangements (based on code and scrubbing frequency) are investigated and evaluated.

A Comparative Study into “Gere Geometric Designs” in Islamic Architecture and Principle of “Perceptual Creation” in the Mystical Thoughts of Ibn Arabi

This article is an analytic and comparative study into abstract patterns of geometric designs, as one of the most significant spaces in the Islamic architecture, and the principle of perceptual creation. It has a comparative approach to investigate equivalence, effigy, and analogies between the micro and macro systems (in the hierarchical system of the universe). In the mystical cosmology of Ib...

Application of cut set method to reliability evaluation of mine ventilation networks

Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...
