to provide reliable information concerning reproductive potential of hippodamia variegata goeze and its prey (aphis fabae), their related life tables were studied under controlled laboratory conditions (at 23?c). the unprocessed data of life tables were analyzed taking the euler-lotka as the basis model. standard error of population growth parameters was calculated using the jackknife re-sampli...
Body size of organisms spans 24 orders of magnitude, and metabolic rate and life span present comparable differences across species. This article shows that this variation can be explained in terms of evolutionary entropy, a statistical parameter which characterizes the robustness of a population, and describes the uncertainty in the age of the mother of a randomly chosen newborn. We show that ...
Nowadays, as communication and network technologies evolve in modern life, ensuring the confidentiality of a cryptography system has become critical requirement. The Vigenère cipher is attracting attention specialists, although algorithm problem. problem due to repeating encryption key. As result multiple cryptographic approaches described literature, this paper proposes novel strategy for safe...
polarimetric synthetic aperture radar (pol.-sar) allows us to implement the recognition and classification of radar targets. this article investigates the arrangement of scatterers by sar data and proposes a new look-up table of region (ltr). this look-up table is based on the combination of (entropy h/anisotropy a) and (anisotropy a/scattering mechanism α), which has not been reported up now. ...
Several Indonesian life insurance companies recently faced financial problems due to inadequate pricing and idealistic investment expectation. Growing market insurtech implementation might lead worse conditions in the future. The current mortality table return assumption are too ideal, so more conservative assumptions required get a reasonable annual pure premium range. This research estimated ...
