Storage of sensitive and/or business critical data on portable USB attachable mass storage devices is a common practice. The ability to transport large volumes of data from the standard place of work and then access and process the data on an available PC at a different location provides both convenience and flexibility. However, use of such USB attachable mass storage devices presents two majo...

Cloud computing is a new model of “computing on demand” that is emerging as an alternate to in-house computing. Users “buy” time on these compute-resources as needed without worrying about installing, maintaining or upgrading local infrastructure. Cloud computing is very useful and highly efficient for meeting peak loads, short-term demands, changing user base, and fault tolerance. In associati...

Introduction: Optimization of waste collection systems can reduce waste management costs. In this study, optimization of the waste collection system of district 3 of Yazd municipality of Iran has been investigated using underground containers. Materials and Methods: In this research, after collecting information and performing field inspections, the statistical and raster information obtained ...

this study by the first, was carried out to evaluate and comparing disposal waste management in karaj's hospitals in 1387. interview and observation methods were used to collect data and the study tool was a questionnaire. data were analyzed by the spss, using chi-square and t-test. regarding the condition of infectious waste generation, 64% of the hospitals had a good grade. source separa...

Deduplication is now widely accepted as an efficient technique for reducing storage costs at the expense of some processing overhead, being increasingly sought in primary storage systems [7, 8] and cloud computing infrastructures holding Virtual Machine (VM) volumes [2, 1, 5]. Besides a large number of duplicates that can be found across static VM images [3], dynamic general purpose data from V...

The requirements for a main memory data storage model are both compactness and efficient processing for all database operations. The DBGraph storage model, proposed in this paper, achieves these goals. By representing the entire database in a unique graph-based data structure, called DBGraph, it fully exploits the directaccess capability of main memory systems. For example, Selection, Join and ...

We describe and demonstrate a volume holographic storage system in which a phase-conjugate object beam is reconstructed by the same reference beam that was used for recording. An intermediate hologram is used as a temporary buffer, recorded with its own reference beam and the data-bearing object beam. Reading this buffer hologram with the phase conjugate of its reference beam reconstructs the p...
