In this paper, a hierarchical control approach with three layers is defined to control the crop growth based on climate and economic criteria for tomato greenhouse. Integrated greenhouse management consists of energy, climate, water-fertilizer, crop quality and pest-disease management. The main purpose of a modern greenhouse is to define the information flow, to control optimum material and ene...

Next-generation projects in High Energy Physics will reach again a new dimension of complexity. Information management has to ensure an efficient and economic information flow within the collaborations, offering world-wide up-to-date information access to the collaborators as one condition for successful projects. DESY introduces several information systems in preparation for the planned linear...

This paper describes a workflow management system that was implemented according to the requirements of a Flood forecasting application [1] developed in the CrossGrid project [2]. The flood forecasting application contains several simulation models (meteorological, hydrological, hydraulic) implemented as the grid jobs. A need for a cascade execution of these models has been a motivation for cre...
