Precision Agriculture NDVI 4 cm / pixel GSD. Precision agriculture ( PA) is a farming management strategy based on observing, measuring and responding to temporal and spatial variability to improve agricultural production sustainability. [ 2] It is used in both crop and livestock production. [ 3]
The group of streamlines enclose the green curves ( and ) to form a stream surface. Streamlines, streaklines and pathlines are field lines in a fluid flow . They differ only when the flow changes with time, that is, when the flow is not steady. [ 1] [ 2] Considering a velocity vector field in three-dimensional space in the framework of ...
Ocean thermal energy conversion ( OTEC) is a renewable energy technology that harnesses the temperature difference between the warm surface waters of the ocean and the cold depths to run a heat engine to produce electricity. It is a unique form of clean energy generation that has the potential to provide a consistent and sustainable source of ...
PechaKucha ( Japanese: ぺちゃくちゃ, IPA: [petɕa kɯ̥tɕa], [ 1] chit-chat) is a storytelling format in which a presenter shows 20 slides for 20 seconds of commentary each. At a PechaKucha Night, individuals gather at a venue to share personal presentations about their work. The PechaKucha format can be used, for example, in business ...
Flow visualization is the art of making flow patterns visible. Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to the naked eye without methods to make them this visible. Historically, such methods included experimental methods. With the development of computer models and CFD simulating flow processes (e.g ...
t. e. Biodynamic agriculture is a form of alternative agriculture based on pseudo-scientific and esoteric concepts initially developed in 1924 by Rudolf Steiner (1861–1925). [ 1][ 2] It was the first of the organic farming movements. [ 3] It treats soil fertility, plant growth, and livestock care as ecologically interrelated tasks, [ 4][ 5 ...
The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
The central common point is the line source described above. Fluid is supplied at a constant rate from the source. As the fluid flows outward, the area of flow increases. As a result, to satisfy continuity equation, the velocity decreases and the streamlines spread out. The velocity at all points at a given distance from the source is the same.
