Development of lossless compression algorithms for power system operational data

Development of cloud‐based power system operational data management system

“…DBEA or E-DBEA. From [17], it is clear that entropy after compression obtained with DBEA and E-DBEA is generally much lower than entropy before compression. As there is a sharing of files between the different PCs, the problem of data transfer error is eliminated.…”

“…3a and b, it is visible that the steps followed in 7 bit DBEA and E-DBEA is similar, except binary encoding section. The difference in binary encoding for 7 bit DBEA and E-DBEA can be understood from Table 1 [17]. As the length of character string obtained with E-DBEA is larger than that with DBEA, CR, i.e.…”

“…Differential binary encoding algorithm (DBEA) was developed in [16] for compressing large data array and a high CR is obtained for repetitive data sets. Higher computational burden and failure while compressing a data array containing all zero elements are among some limitations of RLDA [17]. As DBEA fails with many practical datasets, extended-DBEA (E-DBEA) [17] was developed to extend the range of DBEA at the expense of CR.…”

As DBEA fails with many practical datasets, extended-DBEA (E-DBEA) [17] was developed to extend the range of DBEA at the expense of CR. E-DBEA was modified to develop modified-DBEA (M-DBEA) [18] where the output character string comprises printable characters only.…”

Arylnaphthalene lactone analogues: synthesis and development as excellent biological candidates for future drug discovery

“…4 As a representative example, 1arylnaphthalene lactone lignans (Fig. 1, 1-9) 5 are reported to exhibit a lot of biological activities 6 such as antibacterial, 7 antiviral, [8][9][10][11] antitumor, [12][13][14] antiplatelet, 15,16 phosphodiesterase inhibition, 17,18 5-lipoxygenase inhibition, [19][20][21] HIV reverse transcriptase inhibition [22][23][24] and cytotoxic activities. 25 Arylnaphthalene lactone lignans contain two arylpropanoid units, in which the aromatic rings are polyoxygenated (i.e., coniferyl alcohol).…”
