Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 458-469, December 2022., 2022 Graphical Abstract : Aquaponics, hydroponics, stocking density. Abstract Aquaponics incorporates aquaculture with hydroponics, whose principles and operations largely remain untested. Currently, there is a knowledge gap on the performance of aquaponic systems used for fish production under different stocking densities.

Hydrologic Data Assimilation [PDF]
, 2012 Information about hydrologic conditions is of critical importance to real-world applications such as agricultural production, water resource management, flood prediction, water supply, weather and climate forecasting, and environmental preservation. Improved hydrologic condition estimates are useful for agriculture, ecology, civil engineering, water ...

Data assimilation in price formation [PDF]
Inverse Problems, 2020 Abstract We consider the problem of estimating the density of buyers and vendors in a nonlinear parabolic price formation model using measurements of the price and the transaction rate. Our approach is based on a work by Puel (Puel J-P 2002 C. R. Acad.

Cover crops affect soybean yield components, but not grain quality
Agronomy Journal, Volume 114, Issue 6, Page 3193-3205, November/December 2022., 2022 Abstract Cover cropping is mainly used to prevent soil erosion, but the effects of individual cover crops on the subsequent soybean [Glycine max (L.) Merr.] are hardly known. Therefore, two annual field trials with 15 cover crop species and bare fallow as control were conducted in semi‐arid East Austria in 2016 and 2017.

Data Assimilation in Reduced Modeling [PDF]
SIAM/ASA Journal on Uncertainty Quantification, 2017 We consider the problem of optimal recovery of an element $u$ of a Hilbert space $\mathcal{H}$ from $m$ measurements obtained through known linear functionals on $\mathcal{H}$. Problems of this type are well studied \cite{MRW} under an assumption that $u$ belongs to a prescribed model class, e.g. a known compact subset of $\mathcal{H}$.

Effects of fused and blended fertilizers on maize yield and soil properties
Agronomy Journal, Volume 114, Issue 6, Page 3429-3444, November/December 2022., 2022 Abstract The deficiency of secondary and micronutrients negatively affects plant metabolic functions and reduces crop yields. These nutrients are applied in small quantities (<10 kg ha−1) and are physically blended or chemically fused with primary nutrients to enhance uniformity of application.

Journal of Marine Science and Engineering, 2020 A new parameterization for calculating the nonlinear near-bed wave orbital velocity in the shallow water was presented. The equations proposed by Isobe and Horikawa (1982) were modified in order to achieve more accurate predictions of the peak orbital ...

Maize–soybean intercropping: A bibliometric analysis of 30 years of research publications
Agronomy Journal, Volume 114, Issue 6, Page 3377-3388, November/December 2022., 2022 Abstract Maize (Zea may L.)–soybean [Glycine max (L.) Merr.] intercropping is popular in many countries because of its high productivity. However, no studies have explored maize–soybean intercropping via bibliometric methods. Taking the Web of Science database, the visualization applications of CiteSpace and VOSviewer were used to visually analyze the ...

Bayesian data assimilation in shape registration [PDF]
, 2011 In this paper we apply a Bayesian framework to the problem of geodesic curve matching. Given a template curve, the geodesic equations provide a mapping from initial conditions\ud for the conjugate momentum onto topologically equivalent shapes.
