BiVA: Bitcoin Network Visualization & Analysis [PDF]
2018 IEEE International Conference on Data Mining Workshops (ICDMW), 2018 We showcase a graph mining tool, BiVA, for visualization and analysis of the Bitcoin network. It enables data exploration, visualization of subgraphs around nodes of interest, and integrates both standard and new algorithms, including a general algorithm for flow based clustering for directed graphs, and other Bitcoin network specific wallet address ...

Technology of two-dimensional bioimpedance analysis of the human body composition
Journal of Electrical Bioimpedance, 2021 The BIA primary result sheets as a rule contain one-dimensional graphical scales with a selected area of normal values. In 1994, Piccoli et al. proposed BIVA, an alternative form of BIA data presentation, where two bioimpedance parameters are considered ...

Bioelectrical impedance vector analysis (BIVA) in stable preterm newborns [PDF]
Jornal de Pediatria, 2012 To observe the behavior of the plotted vectors on the RXc (R - resistance - and Xc - reactance corrected for body height/length) graph through bioelectrical impedance analysis (BIVA) and phase angle (PA) values in stable premature infants, considering the hypothesis that preterm infants present vector behavior on BIVA suggestive of less total body ...
