25. Magnetic topology with axial flux concentration: a technique to improve permanent-magnet motor performance
Abstract This article presents a different topology for the magnetic circuit of permanent-magnet motors, using the concept of Axial Flux Concentration. By means of longitudinal extension of the rotor length beyond the stator core, a substantial increase in the flux per pole is enabled, improving the general performance of the machine. Even in low cost motors

26. Morphological and genetic diversity in Callithrix hybrids in an anthropogenic area in southeastern Brazil (Primates: Cebidae: Callitrichinae)
ABSTRACT Two species of Callithrix, C. jacchus (Linnaeus, 1758) and C. penicillata (É. Geoffroy, 1812), are considered invasive in Rio de Janeiro. This study determined the genetic and morphological diversity and verified the species involved in the hybridization of 10 individuals from the municipalities of Silva Jardim (N = 9) and Rio das Ostras (N = 1).

27. Updated angiosperm family tree for analyzing phylogenetic diversity and community structure
ABSTRACT The computation of phylogenetic diversity and phylogenetic community structure demands an accurately calibrated, high-resolution phylogeny, which reflects current knowledge regarding diversification within the group of interest. Herein we present the angiosperm phylogeny R20160415.new, which is based on the topology proposed by the Angiosperm Phylog

28. LCL-T Resonant Converter Based on Dual Active Bridge Topology in Solar Energy Applications
ABSTRACT: Resonant LCL-T converter can operate as stable voltage source, being fed from current, for instance, the photovoltaic battery. It is shown that LCL-T resonant tank has intrinsic ability to convert stable AC current into stable AC voltage thus parametrically regulating output voltage at a fixed value. This mode of operation is made possible by the u

29. Continuum Structural Layout in Consideration of the Balance of the Safety and the Properties of Structures
Abstract In the article, a new approach considering structural local failure for topology optimization of continuum structure is proposed. It aims at not only lowering the risk of local failure in the concerned structural regions, but also ensuring a good stiffness of the structure. The local failure may be caused by the structural uncertainties or possible

30. Structural Analysis of the Double Bottom Structure During Ship Grounding by Finite Element Approach
Abstract Possibility of a water-transportation mode to experience numerous accidental loads is predicted limitless and always demand sustainable analysis. Impact phenomenon raises as main reason of environmental damage, for instance, grounding contributes in form of short-time impact and produces massive damage on the bottom structure of a marine vessels, e.

31. Spectrum Continuity and Contiguity based Dedicated Protection for Flexible Optical Networks
Abstract Elastic optical networks (EONs) have been pointed out as a promising candidate for transporting data with high transmission rates in adaptive optical networks. Consequently, the occurrence of a failure in a simple element may cause the interruption of various services. Survival mechanisms have been crucial to try to overcome the problems created by

32. MOLECULAR IDENTIFICATION OF SIX SPECIES OF CALLIPHORIDAE (DIPTERA) WITH FORENSIC INTEREST IN BOGOTÁ, COLOMBIA
ABSTRACT Taxonomic identification of the species involved in the processes of cadaveric decomposition is a fundamental procedure in forensic entomological analysis. Among the species involved in the processes of decay, those of the Calliphoridae family are particularly important because they come to the body in the early stages of decomposition. The aim of t

33. A Backtracking Search Algorithm for the Simultaneous Size, Shape and Topology Optimization of Trusses
Abstract This paper presents a Backtracking Search Optimization algorithm (BSA) to simultaneously optimize the size, shape and topology of truss structures. It focuses on the optimization of these three aspects since it is well known that the most effective scheme of truss optimization is achieved when they are simultaneously considered. The minimization of

34. Boolean Operators to Improve Multi-Objective Evolutionary Algorithms for Designing Optical Networks
Abstract The physical topology design (PTD) of optical networks is frequently accomplished by combining several solutions in an iterative way, especially if meta-heuristics are deployed for this purpose. Suitable operators to recombine information of network topologies aiming at creating innovative options for designing networks are very useful. Operators th

35. Numerical Simulation for the Collision Between Side Structure and Level Ice in Event of Side Impact Scenario
Abstract With the opening of the Northern Sea for international shipping routes, various vessels prefer to use this option to reach Europe as distance is significantly reduced if a ship is sailing through this route. In the same time, the demand to ensure ship safety rises as impact phenomenon between ship structures and ice causes numerous casualties. This

36. Topological and Topographical Optimization of Automotive Spring Lower Seat
Abstract The design of a suspension system emphasizes weight reduction in this high-computation technology era. Understanding that the reduction of suspension mass can lead to cost and material reduction is important; moreover, the riding performance of the vehicle should be improved. Topology and topography structure optimization for the spring lower seat i
