A Business Intelligence Approach to Support a Greenhouse Tomato Crop Grey Mould...
Neto, Miguel; Baptista, Fátima; Navas, L.M.; Ruiz, G.This paper presents a Business Intelligence architecture proposal, including data sources, data warehouse, business analytics, and information delivery, to launch an early warning system for greenhouse tomato crop grey mould disease. Tomato is a very important crop in the Mediterranean region in general and in Portugal in particular being the production for fresh consumption made essentially in greenhouses. Bot...
Greenhouse Energy Consumption for Rose Production in Different Regions of Portu...
Baptista, F.J.; San Jose, E.; Guimaraes, A.C.; Navas, L.M.; Meneses, J.F.In this work results of an energy consumption study for rose production in multi-tunnel greenhouses, located in Porto (Pedras Rubras), Marinha Grande, Dois Portos, Zambujeira, Faro, Funchal and Ponta Delgada, are presented. The greenhouse considered with a surface area of about 1 ha had galvanised steel structure and was covered with three layer co-extruded plastic films. It was equipped with a hot water heatin...
Greenhouse Energy Consumption for Tomato Production in the Iberian Peninsula Co...
Baptista, F.J.; Silva, A.T.; Navas, L.M.; Guimaraes, A.C.; Meneses, J.F.Greenhouse climate models are a powerful tool which allows the simulation of inside environmental conditions as a function of external conditions, construction and environmental control equipments characteristics. They also permit to evaluate the energy consumption necessary to obtain the predefined conditions. A theoretical study of the greenhouse energy requirements for all year round tomato production in Por...
A Greenhouse Tomato Crop Grey Mould Disease Early Warning System
Neto, M.; Baptista, F.J.; Navas, L.M.; Ruiz, G.Tomato is a very important crop in the Mediterranean region in general and in Portugal in particular being the production for fresh consumption made essentially in greenhouses. Botrytis cinerea Pers.: Fr. is the causal agent of grey mould disease and is one of the most important diseases affecting greenhouse tomato crops, high relative humidity and the presence of free water on the plant surfaces have been reco...
SIMULACIÓN CLIMÁTICA DE INVERNADEROS EN DIFERENTES REGIONES DE PORTUGAL: ESTIMA...
San José, E.; Baptista, F.; Navas, L.M.; Guimarães, A.; Fitas da Cruz, V.En el presente trabajo se muestran los resultados de un estudio de viabilidad técnica y económica de la instalación de un invernadero calefactado en seis zonas de Portugal (Dois Portos, Faro, Marinha Grande, Ponta Delgada, Porto y Zambujeira). Se tomaron como referencia tres cultivos con distintos requerimientos energéticos (tomate, fresa y lechuga). En todos los casos analizados se empleó un invernadero multit...
DEFINICIÓN DE UN PROTOCOLO PARA LA REALIZACIÓN DE AUDITORÍAS ENERGÉTICAS EN INS...
Navas, L.M.; Baptista, F.J.; Hernández, P.; Guimarães, A.; Sanz, J.; Fitas da Cruz, V.; González, F.; Ruiz, G.En el presente trabajo se muestran los resultados de un proyecto desarrollado en España bajo los auspicios del Instituto para la Diversificación y Ahorro de la Energía (IDAE), el Ente Regional de la Energía de Castilla y León (EREN) y la Unión de Pequeños Agricultores (UPA), y aplicado en la región de Castilla y León, zona con un perfil productivo eminentemente agrícola y ganadero, cuyo objetivo fue la definici...
DEVELOPMENT OF A SCADA SYSTEM FOR ACCESS, PROCESSING AND SUPERVISION OF DATA CO...
Navas, L.M.; Martin, E.; Ruiz, G.; Guimarães, A.; Gil, J.; González, F.; Baptista, F.J.; Fitas da Cruz, V.; Neto, M.Wireless sensors networks appeared in the 1970’s for military and industrial use. They have since undergone a major evolution, particularly since the 90’s, thanks to the improvements in wireless communications. These changes have allowed them to participate in a wide variety of applications in different sectors such as agriculture and environment. This paper shows the development of a SCADA application programm...
Auditorias energeticas en instalaciones ganaderas. Parte 1: Manual para la real...
Navas, L.M.; Baptista, F.J.La energía es un medio productivo imprescindible para cualquier tipo de instalación, y en particular por ser el objeto del presente Manual, para las explotaciones ganaderas. Sin embargo, la energía tiene un coste, bien sea por su adquisición o por su autogeneración, por lo que es imprescindible conocer cómo dichas explotaciones contratan el aprovisionamiento de su energía, cómo consumen dicha energía en sus pro...
Determinação de Coeficientes de Transferência de Calor por Convecção em Estufas...
Baptista, F.J.; Navas, L.M.; Fitas da Cruz, V.; Meneses, J.F.; Relea, E.; Guimarães, A.C.A determinação dos coeficientes de transferência de calor por convecção é complexa devido ao elevado número de factores a considerar, tais como a natureza e posição da superfície e a natureza dos fluxos de energia (natureza da convecção, natural, forçada ou mista, e do tipo de fluxo, laminar ou turbulento). A análise pode ser simplificada utilizando os números adimensionais de Grashof (Gr), Reynolds (Re), Prand...
VALIDATION AND COMPARISON OF A PHYSICAL AND A STATISTICAL DYNAMIC CLIMATIC MODE...
Baptista, Fátima J.; Litago, J.; Navas, L.M.; Meneses, J.F.This study is based on the experiments with a tomato crop, carried out in a Mediterranean unheated greenhouse, located at Lisbon. The main objective is to study the comparative performance of a physical and a statistical model to explain and forecast the dynamic of the greenhouse climate, validating their results. External and internal climatic data as well as information on the evolution of the crop were colle...
