1. INTEGRATING REAL TIME OPTIMIZATION AND MODEL PREDICTIVE CONTROL OF A CRUDE DISTILLATION UNIT
Abstract This work reports the integration of Real Time Optimization and Model Predictive Control in the multi-layer control structure of an existing Crude Distillation Unit (CDU) of an oil refinery. The MPC considers output control zones and targets for the inputs or outputs. Both the infinite horizon and the finite output horizon controllers were tested. T

2. Fuzzy Classification in the Determination of Input Application Zones
ABSTRACT Correctly interpreting soil fertility and its spatial distribution within an area helps to lessen losses and environmental effects associated with agriculture, to optimize fertilization and liming practices. This study is aimed at using concepts and methods from spatial and temporal analyses to soil fertility and to develop a fuzzy classification me

3. Variabilidade espacial e temporal das propriedades quÃmicas do solo e das folhas, qualidade do fruto e produtividade em pomar de laranja Monte Parnaso
The plant nutritional quality influences directly in juice quality. Therefore it is important the knowledge of its spatial and temporary variation in the orchard for a better application and use of the inputs, larger yield and quality of fruit. This way, input maps can be generated for the best use, providing larger yield and better quality of fruits, reduct

4. Definition of management zones in coffee production fields based on apparent soil electrical conductivity
Fertilizer application at variable rates requires dense sampling to determine the resulting field spatial variability. Defining management zones is a technique that facilitates the variable-rate application of agricultural inputs. The apparent electrical conductivity of the soil is an important factor in explaining the variability of soil physical-chemical p

5. Gestão de agregados minerais : análise e subsídios para políticas públicas / Management ggregates : comparite analysis betwen Canada and Brazil and subsidies for public policies
The biophysical and social disruption caused by aggregates mining has placed it at the center of conflict scenarios, either because of advancing urbanization on the aggregates resources or because of pressures from civil society to impose restrictions on their development. The search for solutions to this problem has required of the governments a large abili

6. Uso da geoestatística e da lógica fuzzy no estudo da variabilidade espacial e temporal da produtividade e da fertilidade do solo em café conilon
Nos últimos anos, vem aumentando a adoção das técnicas de agricultura de precisão (AP) em culturas anuais e perenes no Brasil. Porém, para a cafeicultura de montanha estão sendo realizadas pesquisas para adaptação de soluções tecnológicas viáveis na aplicação das técnicas de AP. O objetivo desta pesquisa foi utilizar os conceitos e métodos d

7. AVALIAÃÃO DO REVESTIMENTO A BASE DE LIGA DE NÃQUEL EM AÃO ESTRUTURAL, EMPREGANDO O METAL DE ADIÃÃO ERNiCrMo-3 ATRAVÃS DA SOLDAGEM MIG/MAG / EVALUATE OF NICKEL WELD OVERLAY IN STRUCTURAL STEEL, WITH EMPLOYMENT OF GMAW ERNiCrMo-3 ELECTRODE.
The use of nickel alloy cladding components could be more frequently in petroleum industry. The crescent naphthenic corrosion and high molecular weight of national petroleum contribute for needs of materials with more resistance to corrosion, to temperature and to pressure. At this way, how part of systematic study, this work pretends to define operational r

8. APPLICATION OF PRECISION AGRICULTURE TECHNIQUES IN SMALL FARMERS / APLICAÇÃO DE TÉCNICAS DE AGRICULTURA DE PRECISÃO EM PEQUENAS PROPRIEDADES
The adoption of precision agriculture techniques finds great limitation because of the high cost, not always guaranteeing the expected economic return. Among the consequence of this elevated cost it is the restriction use of this technology in small farmers, characterized by the family farm. The present work approaches a bibliographical study about the situa

9. Specialization of primary auditory cortex processing by sound exposure in the “critical period”
Environmental acoustic exposure to a complex tone sequence within the critical period in infant rats resulted in the emergence of large-scale, selective changes that radically altered primary auditory cortex (A1) organization. In the sound exposure-revised A1, responses were segregated into two explicit zones representing spectrally and temporally separated

10. Design Strategy for Flexible Health Sciences Facilities
A statistical analysis of spatial allocations in university teaching hospitals and medical schools in three countries supports the hypothesis that on the “macro” level of major functional zones there is a considerable degree of invariance in space ratios, despite wide divergence in size, organization, and operating policies. On the basis of these finding

11. A revised view of sensory cortical parcellation
Traditional cortical parcellation schemes have emphasized the presence of sharply defined visual, auditory, and somatosensory domains populated exclusively by modality-specific neurons (i.e., neurons responsive to sensory stimuli from a single sensory modality). However, the modality-exclusivity of this scheme has recently been challenged. Observations in a

12. Metabolic Status of Bacteria and Fungi in the Rhizosphere of Ponderosa Pine Seedlings
We determined the quantity and metabolic status of bacteria and fungi in rhizosphere and nonrhizosphere soil from microcosms containing ponderosa pine seedlings. Rhizosphere soil was sampled adjacent to coarse, fine, or young roots. The biovolume and metabolic status of bacterial and fungal cells was determined microscopically and converted to total and acti
