Diameter and height growth analysis for individual White Pine trees in the area of Kostelec nad Černými lesy

open access: yesJournal of Forest Science, 2003
Four theoretical growth functions, Mitscherlich, Logistic, Gompertz and Korf functions, were applied to the growth data on dbh and tree height of individual Eastern White Pine (Pinus strobus) trees to model their growth.

A Modification of the Gompertz Distribution Based on the Class of Extended-Weibull Distributions

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
This paper introduces a new four-parameter extension of the generalized Gompertz distributions. This distribution involves some well-known distributions such as extension of generalized exponential, generalized exponential, and generalized Gompertz ...

Modelling the lactation curve of dairy cows using the differentials of growth functions [PDF]

open access: yes, 2008
Descriptions of entire lactations were investigated using six mathematical equations. comprising the differentials of four growth functions (logistic. Gompertz, Schumacher and Morgan) and two other equations (Wood and Dijkstra).

Precision livestock farming: real-time estimation of daily protein deposition in growing–finishing pigs

open access: yesAnimal, 2020
Precision feeding using real-time models to estimate daily tailored diets can potentially increase nutrient utilization efficiency. However, to improve the estimation of amino acid requirements for growing–finishing pigs, it is necessary to accurately ...

Droplet-based digital antibiotic susceptibility screen reveals single-cell clonal heteroresistance in an isogenic bacterial population [PDF]

open access: yes, 2020
Since antibiotic resistance is a major threat to global health, recent observations that the traditional test of minimum inhibitory concentration (MIC) is not informative enough to guide effective antibiotic treatment are alarming.

Influence of aggregate chemical composition on the demulsification rate of emulsified asphalt

open access: yesFrontiers in Materials, 2022
Efficient demulsification is vital for the application of emulsified asphalt in road construction. In this paper, the effects of the main chemical components of the aggregates (CaCO3, MgO, Fe2O3, SiO2, Al2O3) on the demulsification process of emulsified ...

Generalized Gompertz-power series distributions

open access: yes, 2015
In this paper, we introduce the generalized Gompertz-power series class of distributions which is obtained by compounding generalized Gompertz and power series distributions.

On Bivariate Exponentiated Extended Weibull Family of Distributions [PDF]

open access: yes, 2015
In this paper, we introduce a new class of bivariate distributions called the bivariate exponentiated extended Weibull distributions. The model introduced here is of Marshall-Olkin type.
