Command following and disturbance rejection for drillstring systems
(2000)In this paper a P-D state feedback law is proposed to control the angular velocity of the bit of an drillstring system. The design objective is: the angular velocity of the bit to follow a desired signal independently from ... -
Comparative calculation of irrigation networks using Labye's method, the linear programming method and a simplified nonlinear method
(2010)The designating factors in the design of branched irrigation networks are the cost of pipes and the cost of pumping. They both depend directly on the hydraulic pump head. It is mandatory for this reason to calculate the ... -
A Comparison between Variable Deficit Irrigation and Farmers’ Irrigation Practices under Three Fertilization Levels in Cotton Yield (Gossypium hirsutum L.) Using Precision Agriculture, Remote Sensing, Soil Analyses, and Crop Growth Modeling
(2022)The major global challenge for the coming decades will be increasing crop production with less water consumption. Precision agriculture (PA) and variable deficit irrigation (VDI) are management strategies that help farmers ... -
Could irrigation and N-fertilization affect saffron yield?
(2020)Crocus sativus belongs to the Iridaceae family, and it is known as saffron. The aim of this study was to investigate the effect of irrigation and N-fertilization on the produced number and weight of flowers and stigmas. A ... -
Development of a district information system for water management planning and strategic decision making
(2015)The overall objective of this work is the development of a District Information System (DIS) which could be used by stakeholders for the purposes of a district day-to-day water management as well as for planning and strategic ... -
Economical and social aspects: Evaluation of incorporation potential in municipal wastewater reuse procedure in Greece
(2006)It is the objective of this study to evaluate the incorporation potential of economic and social factors in municipal wastewater reuse procedure, aiming at determining whether it is worthwhile for a municipality to construct ... -
Effect of irrigation frequency on rose flower production and quality
(2006)A better understanding of the effects of irrigation frequency on flower production and quality of rose plants can help to propose optimal irrigation scheduling. For this purpose, experiments were conducted on a soilless ... -
The effect of sorptivity on cumulative infiltration
(2021)Hydraulic parameters of the soil play a considerable role in the hydrological cycle, irrigation planning, drainage, groundwater recharge, and water resources management. One of the most important hydraulic parameters of ... -
Energy needs and energy saving in Mediterranean greenhouses
(2014)A fully-automated and climate-controlled greenhouse requires heating, ventilation, cooling, dehumidification and shading systems to control the microclimate conditions and create an optimal environment for crop growth and ... -
Estimation of crop water requirements using remote sensing for operational water resources management
(2015)An integrated modeling system, developed in the framework of "Hydromentor" research project, is applied to evaluate crop water requirements for operational water resources management at Lake Karla watershed, Greece. The ... -
Evaluation of seed cotton (Gossypium hirsutum L.) production and quality in relation to the different irrigation levels and two row spacings
(2012)The effect of row spacings and irrigation levels on the earliness of seed production of cotton was investigated under the Mediterranean environment of central Greece. This particular cotton growing area is exposed to risk ... -
Growth and biomass productivity of kenaf (Hibiscus cannabinus, L.) under different agricultural inputs and management practices in central Greece
(2010)The growth and biomass productivity of kenaf (Hibiscus cannabinus, L.) cultivars Tainung 2 and Everglades 41 were determined under three irrigation applications (low: 25%, moderate: 50% and fully: 100% of maximum ... -
Hyperspectral machine vision as a tool for water stress severity assessment in soilless tomato crop
(2018)Early detection of water deficit stress is essential for efficient crop management. In this study, hyperspectral machine vision was used as a non-contact technique for detecting changes in spectral reflectance of a soilless ... -
Identification of the key variables that can be estimated using remote sensing data and needed for Water Footprint (WF) assessment
(2014)Accurate assessment of water use is an important issue in a globally changing climate and environment, where water is becoming a scarce but essential resource. The concept "?Water Footprint (WF) of a crop is defined as the ... -
Impacts of irrigation and nitrate fertilization scenarios on groundwater resources quantity and quality of the Almyros Basin, Greece
(2021)Irrigation and nitrate fertilization scenarios were combined and simulated for crop water irrigation demands and nitrogen applications based on experiments on crop cultivation practices. Two irrigation practices (deficit ... -
Integrated Hydro-Economic Modeling for Sustainable Water Resources Management in Data-Scarce Areas: The Case of Lake Karla Watershed in Greece
(2019)Hydro-economic models can serve as valuable tools to improve the understanding of system details, as well as to support decision-making and water resources management. However, hydro-economic models are not practically ... -
