Composition for cardinal directions by decomposing horizontal and vertical constraints [PDF]

open access: yes, 2003
In this paper, we demonstrate how to group the nine cardinal directions into sets and use them to compute a composition table. Firstly, we define each cardinal direction in terms of a certain set of constraints.

Determining cardinal temperatures for eight cover crop species

open access: yesAgrosystems, Geosciences & Environment, 2023
Growing degree days (GDD) is a tool to predict plant growth and can be adapted for use in any plant species, including cover crops. A limitation of the GDD calculation is accurate temperature parameters used to predict plant development.

An expressive hybrid model for the composition of cardinal directions [PDF]

open access: yes, 2003
In our previous paper (Kor and Bennett, 2003), we have shown how the nine tiles in the projection-based model for cardinal directions can be partitioned into sets based on horizontal and vertical constraints (called Horizontal and Vertical Constraints ...

Evaluation of germination characteristics and determination of cardinal temperatures of poppy (Papaver somniferum) seed [PDF]

open access: yesعلوم و فناوری بذر ایران, 2017
The aim of this study was to quantify the response of germination rate to temperature and to find cardinal temperatures required for different germination percentiles in Papaver somniferum. Four models of non-linear regression [Quadratic, Segmented, Beta

Voting and the Cardinal Aggregation of Judgments [PDF]

open access: yes, 2004
The paper elaborates the idea that voting is an instance of the aggregation of judgments, this being a more general concept than the aggregation of preferences. To aggregate judgments one must first measure them.
