2. Performance Analysis of Small Grid Connected Photovoltaic Systems
Abstract The acceptance and deployment of electric power from sustainable sources, which are less polluting than fossils, have been a consensus throughout society. Specially, the growth of the installed capacity in photovoltaic energy has been considerable in distributed generation. In order to properly take advantage of this growing demand, it is necessary

3. SORM DG - an efficient SORM based on differential geometry
Abstract The first order reliability method (FORM) efficiently performs first order structural reliability analysis, but with limited accuracy. On the other hand, the traditional second order reliability method (SORM) was established to improve the results of FORM, but with a supplementary computational process. Proposed herein, is a new SORM, based on diffe

4. Analysis of the contribution of the block-soil contact in piled foundations
Abstract Geotechnical engineering has often been challenged by demands from technically and economically bold construction projects, such as that of tall buildings. The architectural requirements of these buildings have increased and concentrated the loads from structural systems without proportionally increasing plant area. New forms of using load capacity

5. Experimental and numerical investigation on the shock characteristics of U-notched ZL205A specimens under dynamic mixed-mode loading
Abstract Shock environment assessment and improvement during stage separation is an important issue of concern in aerospace engineering. This paper focuses on shock response caused by dynamic fracture of aluminum alloy separation plate, which usually undergoes mixed mode loading during separation. Based on Split Hopkinson Tensile Bar (SHTB) apparatus, five g

6. Analysis of sensor placement in beams for crack identification
Abstract A previous study has shown that the mode shapes of a beam are more sensitive to damage than other vibrational parameters, thus making them better suited for crack identification purposes. However, they have the disadvantage of being more difficult to be measured. To overcome this difficulty, an interesting idea is to monitor changes produced by crac

7. The Effectiveness of Thin-Walled Hull Structures Against Collision Impact
Abstract The impact phenomenon is one of many subjects that is interesting and has become an inseparable part of naval architecture and ocean engineering fields. Limitless possibilities in cause and scenario make the demand to understand the physical behavior of ship structures due to impact phenomenon is increasing. In present work, a series of virtual expe

9. Gender Differences and Professional Identities in Health and Engineering
Abstract The objective of this study was to compare the professional identity perceptions among undergraduate students enrolled in predominantly female and male courses. The research method is cross-sectional and the sample consisted of 502 undergraduate students in the fields of health and engineering. A questionnaire with the Scale of Professional Self and

10. Structural analyses of reinforced tubular T-joints
Abstract The use of rolled hollow sections has been substantially boosted mainly due to the advantages associated with structural behavior and aesthetics, leading to an intense use in Europe, Southeast Asia, North America, Australia, and now, in Brazil due to the wider supply of these profiles. Therefore, it is important to investigate the structural behavio

11. Structural and Thermo-mechanical Evaluation of Two Engineering Thermoplastic Polymers in Contact with Ethanol Fuel from Sugarcane
Special polymers have been used in the manufacture of storage structures and pipelines avoiding corrosive processes during ethanol fuel transport/storage. Therefore, this work investigated comparatively the effects of the ethanol on the physical-mechanical properties of poly (ether ether ketone) (PEEK) and polyamide 11 (PA-11) based on ageing tests. The WAXD

12. Geometrically nonlinear analysis of thin-walled laminated composite beams
Abstract The use of thin-walled composite beams in Engineering has attracted great interest in recent years. Composite beams and other structural elements tend to have thin walls due to the high strength of the material. Other important aspect is that, even without reaching large strains and without overcoming the elastic limit of the material, such as beams
