Emerging non-volatile memory technologies as a disk drive replacement raise some issues of software stack and interfaces, which have not been considered in disk-based storage systems. In this work, we present new cooperative schemes including software and hardware to address performance issues with deploying storage-class memory technologies as a storage device. First, we propose a new polling ...

This paper contains analysis of concept of a class within different object-oriented knowledge representation models. The main attention is paid to structure of the class and its efficiency in the context of data storage, using object-relational mapping. The main achievement of the paper is extension of concept of homogeneous class of objects by introducing concepts of single-core and multi-core...

The emergence of more reliable, often much faster solid-stage storage devices is revolutionizing most aspects of data storage technology. Here we address the impact of these new storage devices on the techniques used to ensure data survival. In particular, we show that the higher bandwidth-to-capacity ratios of the new Storage Class Memory devices will make selfadaptive storage solutions much m...

The high repair cost of (n, k) Maximum Distance Separable (MDS) erasure codes has recently motivated a new class of codes, called Regenerating Codes, that optimally trade off storage cost for repair bandwidth. On one end of this spectrum of Regenerating Codes are Minimum Storage Regenerating (MSR) codes that can match the minimum storage cost of MDS codes while also significantly reducing repai...

Given a picker-to-part warehouse having a simple rectilinear aisle arrangement with north2 south storage aisles and east-west travel aisles (or “cross aisles”), this paper investigates the 3 optimal placement of the cross aisles as a consequence of the probability density function of the 4 order pick locations, as determined by the storage policy. That is, for a given storage policy, 5 what pla...

Automated Storage and Retrieval Systems (AS/RSs) are warehousing systems that are used for the storage and retrieval of products in both distribution and production environments. This paper presents an open-rack structure with unidirectional-upward mobile loads within the rack, for miniload AS/RS, in which the stacker crane is only used for the retrieval operations, and the storage operations a...

considering that once-through benson boiler is one of the most crucial equipment of a thermal power plant, occurrence of any fault in its different parts can lead to decrease of the performance of system, and even may cause system damage and endanger the human life. in this paper, due to the high complexity of the system's dynamic equations, we utilized data-based method for diagnosing the faul...
