About adaptive coding on countable alphabets [PDF]
, 2014 This paper sheds light on universal coding with respect to classes of memoryless sources over a countable alphabet defined by an envelope function with finite and non-decreasing hazard rate. We prove that the auto-censuring AC code introduced by Bontemps

Ecotoxicological characterization of hazardous wastes
Ecotoxicology and Environmental Safety, 2008 In Europe hazardous wastes are classified by 14 criteria including ecotoxicity (H 14). Standardized methods originally developed for chemical and soil testing were adapted for the ecotoxicological characterization of wastes including leachate and solid phase tests. A consensus on which tests should be recommended as mandatory is still missing.

On Extended Quadratic Hazard Rate Distribution: Development, Properties, Characterizations and Applications [PDF]
, 2018 In this paper, we propose a flexible extended quadratic hazard rate (EQHR) distribution with increasing, decreasing, bathtub and upside-down bathtub hazard rate function. The EQHR density is arc, right-skewed and symmetrical shaped.
