The foundation of all plant production systems is the effective, efficient and dependable means of nutrient delivery to the plant. The nutrient delivery system directly influences the physical components and the plant culture tasks of the plant management technique within the controlled environment agriculture system. The nutrient delivery system can be described in terms of its mechanism for w...

2 Architecture In this paper, firstly we discuss the architecture of a flexible automated production system under which all components are well-modulized. Then, a solution, EMFAK(Event-driven Multi-tasking Flexible Automation Kernel) is proposed to speed up the construction of system control. At last, a flexible assembly system using EMFAK is described to show how to apply it to a real flexible...

Design and implementation of data warehouses remain delicate tasks which are led by experts. Nevertheless it would be interesting to allow the users to define and to build themselves their system through a simple and flexible process. In particular, in the field of production systems, exists the need to integrate data from various sources and to analyze them in order to extract knowledge for op...

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypotheses are put forward to explain the different beha...

Agricultural production system is an outcome of a complex interaction of seed, soil, water and agro-chemicals (including fertilizers). Therefore, judicious management of all the inputs is essential for the sustainability of such a complex system. The focus on enhancing the productivity during the Green Revolution coupled with total disregard of proper management of inputs and without considerin...

We aim at the realization of automatic contents production system of commentary soccer video based on digital shooting technique which is composed of digital camera work and digital switching technique. The digital camera work is defined as virtual panning and virtual zooming. the virtual panning is a video production technique of clipping a size fixed frame by controlling frame location on a h...

background determinants of health or health production function in health economics literature constitute noticeable issues in health promotion. this study aimed at estimating a health production function for east mediterranean region (emr) based on the grossman theoretical model.   methods this ecological study was performed using the econometric methods. the panel data model was used in order...
