Cím: Variable Rate Precision Irrigation Technology for Deficit Irrigation of Processing Tomato
Szerző: ; ; ;
Dátum: 2018
Feltöltve: 2023-03-07
(2018)
"Centre pivot machines, with a variable rate irrigation (VRI) package that provides individual sprinkler control systems (VRI iS), are not common. This research focuses on how uniform the water distribution is under VRI ...
Cím: Questions in the quantitative analysis of sediment load - example of three major rivers in Hungary
Szerző: ;
Dátum: 2018

(2018)
The importance of the monitoring of sediment processes is unquestionable: sediment balance of regulated rivers suffered substantial alterations in the past century, affecting navigation, energy production, fish habitats ...
Cím: Extracting Water-Related Features Using Reflectance Data And Principal Component Analysis Of Landsat Images
Szerző: ; ; ; ;
Dátum: 2018
Feltöltve: 2023-03-07
(2018)
This study aimed to map water features using a Landsat image rather than traditional land cover. We involved the original bands, spectral indices and principal components (PCs) of a principal component analysis (PCA) as ...
Cím: Analysis of Reverse Osmosis Filter Permeability
Szerző: ; ;
Dátum: 2018
Feltöltve: 2023-02-20
(2018)
Unsuitable feed water quality causes fouling and serious decrease in membrane permeability during the operation of reverse osmosis filters, which leads to costly operation and low contaminant removal efficiency. The purpose ...
Cím: Restricted Lonesum Matrices

(2018)
"Lonesum matrices are matrices that are uniquely reconstructible from their row and column sum vectors. These matrices are enumerated by the poly-Bernoulli numbers"," a sequence related to the multiple zeta values with a ...
Cím: Bijective enumerations of ?-free 0–1 matrices

We construct a new bijection between the set of n × k 0–1 matrices with no three 1’s forming a ? configuration and the set of ( n, k )-Callan sequences, a simple structure counted by poly-Bernoulli numbers. We give two ...
Cím: Effect of Aeration on Residence Time in Biological Wastewater Treatment
Szerző:
Dátum: 2018
Feltöltve: 2023-02-20
(2018)
Aerobic wastewater treatment requires extensive aeration, which primary function is to provide oxygen to the biomass responsible fordegradation of wastewater constituents. Besides the effective oxygen transfer efficiency ...
