Data Recovery - an overview | ScienceDirect Topics 1.2.2.3 Data recovery. At the data maintenance stage of the Cloud data life cycle, replicas could be lost due to storage failures. In order to either restore the redundancy level of the Cloud data or prevent the data from total loss, data recovery is needed. At this stage, certain mechanisms are conducted to recover the lost replicas.

Waste heat recoveries in data centers: A review - ScienceDirect A review of data center cooling technology, operating conditions and the corresponding low-grade waste heat recovery opportunities Renewable and sustainable energy reviews , vol. 31 , Elsevier Ltd ( 2014 ) , pp. 622 - 638 , 10.1016/j.rser.2013.12.007

Demonstration of all-digital burst clock and data recovery for ... Burst clock and data recovery (BCDR) has not yet been reported on symmetrical single-wavelength 50 Gb/s PAM-4 PON over the same fiber link based on bandwidth limited optics. Various BCDR techniques have been proposed for Non-Return-to-Zero (NRZ)signals, such as phase locked loops (PLL), gated-voltage controlled oscillators (G-VCO) and over ...

Data recovery in a case of fire-damaged Hard Disk Drives and Solid ... Fortunately, the owners of the drives reacted quickly. All the drives were referred to the data recovery service immediately after they had been recovered. Before any attempts to read the data, the drives were disassembled, and their electronic components were removed and thoroughly cleaned with 99,9% isopropyl alcohol (IPA).

Missing measurement data recovery methods in structural health ... The missing sensor data is treated as an unknown variable for data recovery, decoding vector y l, and determining the decoding measurement matrix Φ l according to the missing data case. The generated measurement matrix needs to ensure that the random matrix has sufficient sparsity and randomness to ensure the performance of the CS algorithm.

Development and composition of a data center heat recovery system and ... Enormous research has been devoted to the heat recovery of data center. Ebrahimi et al. [3] summarized a number of currently available and developmental low-grade waste heat recovery techniques, such as district/plant/water heating, absorption cooling, direct power generation (piezoelectric and thermoelectric), indirect power generation (steam and organic Rankine cycle), biomass co-location ...

Nonconvex 3D array image data recovery and pattern recognition under ... Under the tensor framework, we develop the new weighted t-Schatten-p quasi-norm regularizer in the Fourier domain for multi-dimensional datasets, which appears to be feasible in 3D data decomposition in terms of the recovery of the low-rank part and the sparse part, respectively.

All-digital clock and data recovery circuit for USB applications in 65 ... An all-digital clock and data recovery (CDR) circuit is proposed in this work. The modified structure of multi-level bang-bang phase detector (BBPD) is proposed to eliminate the metastability problem at locking time and the phase difference of ±180°.

A systematic analysis of failures in protecting personal health data: A ... In this paper, we embrace the concept of a personal health data breach as “an incident that results in the confirmed disclosure – not just potential exposure – of [personal health] data to an unauthorized party” (Verizon, 2020, p. 4). Personal health data breaches are particularly consequential and can cause serious harm to individuals.

A review of data center cooling technology, operating conditions and ... A number of currently available and developmental low-grade waste heat recovery techniques including district/plant/water heating, absorption cooling, direct power generation (piezoelectric and thermoelectric), indirect power generation (steam and organic Rankine cycle), biomass co-location, and desalination/clean water are reviewed along with their operational requirements in order to assess ...
