Optimal plot size in wheat with comparison of three methods [PDF]

open access: yesRevista Ciência Agronômica, 2023
The objectives of this study were to determine the optimal plot size (Xo) to evaluate the fresh matter productivity of wheat (Triticum aestivum L.) and check whether Xo differs between three determination methods. Five uniformity trials were carried out.

On the Optimal Size of Marine Reserves

open access: yesActa Biotheoretica, 2013
The excessive and unsustainable exploitation of our marine resources has led to the promotion of marine reserves as a fisheries management tool. Marine reserves, areas in which fishing is restricted or prohibited, can offer opportunities for the recovery of exploited stock and fishery enhancement.

Probability estimate and the optimal text size [PDF]

open access: yesPsihologija, 2008
Reliable language corpus implies a text sample of size n that provides stable probability distributions of linguistic phenomena. The question is what is the minimal (i.e. the optimal) text size at which probabilities of linguistic phenomena become stable.

Asymptotic Glosten Milgrom equilibrium [PDF]

open access: yes, 2015
This paper studies the Glosten Milgrom model whose risky asset value admits an arbitrary discrete distribution. Contrast to existing results on insider's models, the insider's optimal strategy in this model, if exists, is not of feedback type.

Batch Size-Invariance for Policy Optimization

open access: yesAdvances in Neural Information Processing Systems 35, 2022
We say an algorithm is batch size-invariant if changes to the batch size can largely be compensated for by changes to other hyperparameters. Stochastic gradient descent is well-known to have this property at small batch sizes, via the learning rate. However, some policy optimization algorithms (such as PPO) do not have this property, because of how ...

Estimating wheat production cost function in Iraq for the agricultural season 2018-2019 (Waist Governorate an applied model).

open access: yesمجلة الدراسات الاقتصادية والادارية
The wheat crop is considered an important strategic food crop and ranks first among field crops in terms of cultivated area and production. Despite the expansion of its cultivation throughout Iraq in general and Wasit Governorate in particular ...

RAISING ECONOMIC EFFICIENCY OF JACKET TECHNOLOGICAL DEVICES AT THE EXPENSE OF DECREASING METAL-CONSUMING AND POWER-CONSUMING CHARACTERISTICS

open access: yesВестник Российского экономического университета имени Г. В. Плеханова, 2018
The article grounds economic expediency of using jacket thermal exchangers of the sheet-canal type. As a rule steam jackets of technological devices in food industry and catering enterprises have a form of an open slit space and for work under pressure ...

The Optimal Inhomogeneity for Superconductivity: Finite Size Studies

open access: yes, 2008
We report the results of exact diagonalization studies of Hubbard models on a $4\times 4$ square lattice with periodic boundary conditions and various degrees and patterns of inhomogeneity, which are represented by inequivalent hopping integrals $t$ and $

Optimal reproductive phenology under size‐dependent cannibalism

open access: yesEcology and Evolution, 2020
Intra‐cohort cannibalism is an example of a size‐mediated priority effect. If early life stages cannibalize slightly smaller individuals, then parents face a trade‐off between breeding at the best time for larval growth or development and predation risk ...
