2. TRANSINDIVIDUALITY AND POST-LABOR BASED ON SIMONDON AND STIEGLER
RESUMO O objetivo deste artigo é elucidar a base filosófica do paradigma pós-laboral por meio da cultura técnica-psiquica-coletiva transindividual de Gilbert Simondon e Bernard Stiegler. Simondon prediz que o problema da alienação laboral surgido da industrialização mecânica pode ser vencido mediante a expansão da cultura técnica pós-industrial b

3. Automation of lettuce seedlings irrigation with sensors deployed in the substrate or at the atmosphere
ABSTRACT: Seedling production is an important step in the lettuce production system. However, there is a tendency to apply excessive irrigation at this stage. The aim of this study was to test the use of the Simplified Irrigation Controller (SIC) under two conditions: first, with the sensor installed in the substrate (measuring the soil water tension) and se

4. Application challenges for information and automation technologies in an underground mine in Brazil
Abstract Organizations can establish a value-added sustainable strategy by increasing asset utilization. WLAN infrastructure in underground mines tends to be a consistent platform for reliability in data/information management, and assertive governance practices. It enables remote monitoring, registering and data transfer from a control room, avoiding unnece

9. Desenvolvimento de um controlador de irrigação para áreas experimentais / Development of an irrigation controller for experimental areas
Irrigation scheduling at experimental areas is determined by several factors, which are mainly related to features of each unit (container or bed) and criteria set by researchers. Many times the experimental areas are greenhouses and depending on the research may be necessary provide mechanisms for monitoring sensors and controlling actuators on each unit in

10. Controle preditivo baseado em modelo neuro-fuzzy de sistemas não-lineares aplicado em sistema de refrigeração = : Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant / Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant
Refrigeration systems can be found in many different branches of industry and are characterized as great energy consumers with considerable non-linear behavior. Several studies have been developed to promote the reduction of energy costs and to minimize the effects of nonlinearities in these systems. The use of automation and process control, particularly th
