International Journal of Adaptive Control and Signal Processing, EarlyView.This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Importance of stand density, inter row spacing, "mother" and "father" row distance in corn seed production [PDF]
Selekcija i Semenarstvo, 2006 Importance of stand density, "mother" and "father" row distance is very important for corn seed production. Inter row spacing from 70,60 and 50 cm, and their influence on "mother" grain yield was investigated during 7 years trials. In seed production, at

On-Farm Corn Row Spacing Trials
, 2015 Over the past several decades there has been a shift in corn row spacing from the traditional 40-in. rows that were needed so horses could fit between the rows, to 38-in., 36-in., and the most popular 30-in. rows. The narrow row spacing usually has resulted in increased yields due to it allowing more space between the plants within the row.

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Influence of inter-row spacing and cultivar on the productivity of soybean [PDF]
Biotechnology in Animal Husbandry, 2014 Influence of inter-row spacing on a productivity of soybean yield was studied on the experimental field on low carbonate chernozem soil. The greatest grain weight per plant (13.22 g) was achieved at the smallest row spacing.

Effects of plant density on alfalfa (Medicago sativa L.) seed yield in western Heilongjiang areas
Open Life Sciences, 2023 Alfalfa (Medicago sativa L.) is known as the “king of forages”. The aim of the current study is to determine the optimum planting density as the key cultivation technique for high yield of alfalfa seed.

Row Spacing with Variable Seeding Rates
, 2008 Current row widths employed by producers typically vary from 15 in. to 38 in., with most producers at 30 in. today. Yet more and more acres are being converted to narrower row widths(most often 15 in. or 20 in.). Numerous advantages exist with narrower row widths.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
