Male-biased effective sex ratio across populations of the threatened Zamia boliviana (Zamiaceae)
(2021-05-01)
Populations of dioecious plants commonly exhibit dissimilarities to the equilibrium expectation of a 1:1 sex ratio. Differential expenditure for reproduction between genders is cited as the primary mechanism responsible ...
Improving head movement tolerance of cross-ratio based eye trackers
(SpringerNova York, 2013-02)
When first introduced, the cross-ratio (CR) based remote eye tracking method offered many attractive features for natural human gaze-based interaction, such as simple camera setup, no user calibration, and invariance to ...

(Universidad EafitMaestría en Administración FinancieraEscuela de Economía y FinanzasMedellín, 2020)
This study analyzes the FCL/sales ratio as a proxy for value in companies in the automotive sector, emphasizing the analysis of value inducers. To carry out the study, we use descriptive and inferential statistics, such ...
Phenology, sex ratio, and spatial distribution among dioecious species of Trichilia (Meliaceae)
(Georg Thieme Verlag Kg, 2004-07-01)
The flowering, sex ratio, and spatial distribution of four dioecious species of Trichilia (Meliaceae) were studied in a semi-deciduous forest in southeastern Brazil. All reproductive trees (T. clausseni, T. pallida and T. ...

Energy ratio (ER) for the standard penetration test based on measured field tests
(2017-08-01)
The Standard Penetration Test (SPT) is often used to estimate the soil parameters for geotechnical design projects, using the NSPT index. However, these estimates are performed based on empirical correlations without any ...
Mathematical expression of the bit error ratio in terms of the SNR and laser linewidths in digital coherent optical communication systems
(2021-01-01)
The development of high speed digital signal processors has enabled the migration from previous direct detection systems to digital coherent optical communication systems. The adoption of this technology in optical ...
Dynamics of choice and frequency of environment change
(2008)
Recent research has examined the effects on behavioral adjustment of a range of within-session changes in the reinforcer ratio available from two alternatives. Regularities between extended patterns of behavior (choice) ...
