1. Two-dimensional spatial distribution modeling of sprinkler irrigation
ABSTRACT Irrigation can provide significant agronomic and financial returns on agricultural activity. The maximization of the benefits obtained from irrigation depends, among other factors, on the water use efficiency, which is intrinsically related to application uniformity. For the sprinkler method, the irrigation uniformity assessment is based on results

2. Some Aspects of Numerical Modeling of Steel-Concrete Composite Beams with Prestressed Tendons
Abstract Aspects about the numerical modeling of three-dimensional prestressed steel-concrete composite beams by using the finite element (FE) method are highlighted and commented in this work. Emphasis is given to the numerical treatment of bonded and unbonded tendons. The proposed modeling technique uses curved beam and catenary elements for simulating int

3. Comparison of 1D and 3D reservoir heat transport models and temperature effects on mass transport
RESUMO Modelos 1D e 3D de transporte de calor são comparados em um reservatório dentrítico no Brasil. Os períodos de estratificação para ambos modelos foram estimados usando índices físicos e gradientes de temperatura. O modelo tridimensional reproduz a temperatura da coluna d'água com mais acurácia, no entanto, o cálculo de índices físicos (nú

4. FUZZY MODELING OF THE EFFECTS OF IRRIGATION AND WATER SALINITY IN HARVEST POINT OF TOMATO CROP. PART II: APPLICATION AND INTERPRETATION
ABSTRACT Tomato, the most popular greenery, is characterized by being a demanding crop in water and when in prolonged and severe drought, has limitations in its growth and reduction in productivity. In addition, this vegetable is affected by excess salinity in the water, which causes leaf wilting, apex and leaf edges burn until their death. Such effects gene

6. Delimiting the concept of organizational commitment: empirical evidence of the overlap between the entrenchment and the continuance mindset
Resumo Na pesquisa sobre comprometimento organizacional predomina o modelo tridimensional de Meyer e Allen que tem sido foco de discussões acerca de possíveis inconsistências, especialmente relacionadas à sua base de continuação. Assim, o presente estudo coloca em pauta o conceito de entrincheiramento organizacional como a tendência do trabalhador a p

7. Maximal Information Coefficient and Support Vector Regression Based Nonlinear Feature Selection and QSAR Modeling on Toxicity of Alcohol Compounds to Tadpoles of Rana temporaria
Efficient evaluation of biotoxicity of organics is of vital significance to resource utilization and environmental protection. In this study, toxicity of 110 alcohol compounds to tadpoles of Rana temporaria is adopted as the dependent variable and 1388 physiochemical parameters (features) calculated by PCLIENT are used for representing each compound. A featu

8. Research on Sliding Mode Method about Three-Dimensional Integrated Guidance and Control for Air-to-Ground Missile
ABSTRACT Based on adaptive sliding mode-control and back-stepping design method, an integrated guidance and control method with less calculation is proposed, which is designed for air-to-ground missile during the terminal course in three-dimensional space. The model of the control system with nonlinear and coupling is simplified, then the integrated guidance

9. Aspects of Finite Element Modeling of Punching Shear Behavior of Reinforced Concrete Flat Slabs
Abstract A series of nonlinear FE analyses was conducted in this paper to model the punching shear failure of RC flat slabs. The analyses were carried out in the software DIANA using three-dimensional continuum elements. These analyses involve the test of different modeling choices in order to evaluate their influences on punching shear failure modeling. The

11. Geological modeling of a stratified deposit with CAD-Based solid model automation
Abstract The planning stages of mining activities require many comprehensive and detailed analyses. Determining the correct orebody model is the first stage and one of the most important. Three-dimensional solid modeling is one of the significant methods that can examine the position and shape of the ore deposit. Although there are many different types of mi
