LayLa: An open-source offline programming framework for composite deposition
The versatility of automated composite technologies granted the possibility of manufacturing laminates with a continuous variation of fiber orientation, also known as Variable Stiffness Laminates (VSL). Despite offering enough dexterity to be adapted for composite deposition, industrial manipulators are nontrivial to integrate into other applications than those originally envisioned, especially when complex curvilinear cartesian paths are desired. Further improvements in layup control and performance are necessary to induce an accurate tracking of fiber tow courses. The goals of this thesis were to a) reduce variability of layup control, b) eliminate experimental iterative steps associated with programming tow courses and c) enforce a constant laydown speed that aids consolidation quality. To achieve such objectives, a framework entitled LayLa (Laying Laminates) was developed as an offline programming tool that automatically computes the series of continuous robot motions to perform a tow course at a desired laydown speed. Experiments with LayLa were conducted for Automated Fiber Placement (AFP) using a six degrees-of-freedom KUKA manipulator, without actual deposition. From a VSL design algorithm, two fiber tow courses with a reduced turning radius were selected to be performed at a laydown speed of 0.1m/s. The overall results revealed reasonably accurate trajectory tracking of both joint and operating space variables, with errors at the end-effector position around 0.05mm and at the laydown speed of 3.2mm/s, corroborating the use of LayLa to create external commands for composite deposition.Aerospace Engineerin

Three-dimensional connectivity index for texture recognition
AbstractThis work proposes a new method of texture analysis for grey-level images based on the distribution of connectivity indexes in local neighbourhoods. The connectivity index acts as a measure of homogeneity of textures and its distribution is computed at various local neighbourhood sizes. The resulting descriptors provide an efficient multiscale representation of connectivity at different scales. The method was tested in the classification of UIUC, Outex, and KTH-TIPS2b databases and outperformed several state-of-the-art approaches, including such as LBP, LBP+VAR, MR8, multifractals among others
Automated Sequential Ultrasonic Welding on a full-scale Thermoplastic Composite Fuselage demonstrator
Multi-spot sequential ultrasonic welding is a promising joining technique for thermoplastic composites in an overlap configuration. In the framework of the EU Clean Sky 2 Multi-functional fuselage demonstrator (MFFD) and the lower shell SmarT multifUNctioNal and INteGrated TP fuselage (STUNNING) projects, a robot-based sequential ultrasonic spot welding process has been developed for joining of large thermoplastic structural components, based on process development steps reported in previous work [1]. The technology is being demonstrated on a full-scale thermoplastic composite fuselage section of 8 m length and 4 m shell radius. The fuselage skin is being joined to longitudinal stringers and circumferential frames through welded clips, in the lower shell of the fuselage demonstrator. This paper presents an overview of the robotic sequential welding technology developed at SAM|XL in collaboration with Delft University of Technology and the ongoing sub-assembly process of the fuselage demonstrator, led by GKN Aerospace.Intelligent Manufacturing systemsDesign for SustainabilityAerospace Structures & Computational Mechanic
Whole-genome analysis of diverse Chlamydia trachomatis strains identifies phylogenetic relationships masked by current clinical typing
Chlamydia trachomatis is responsible for both trachoma and sexually transmitted infections, causing substantial morbidity and economic cost globally. Despite this, our knowledge of its population and evolutionary genetics is limited. Here we present a detailed phylogeny based on whole-genome sequencing of representative strains of C. trachomatis from both trachoma and lymphogranuloma venereum (LGV) biovars from temporally and geographically diverse sources. Our analysis shows that predicting phylogenetic structure using ompA, which is traditionally used to classify Chlamydia, is misleading because extensive recombination in this region masks any true relationships present. We show that in many instances, ompA is a chimera that can be exchanged in part or as a whole both within and between biovars. We also provide evidence for exchange of, and recombination within, the cryptic plasmid, which is another key diagnostic target. We used our phylogenetic framework to show how genetic exchange has manifested itself in ocular, urogenital and LGV C. trachomatis strains, including the epidemic LGV serotype L2b
Dynamically feasible data-driven trajectory generation for high performance control of robot manipulators
Robot manipulators are significantly more accurate than their human counterparts and enhance the repeatability of various tasks. However, manufactures still provide reduced information regarding the robot controller functions, typically affecting robots' predictability. Additionally, industrial examples show that system transparency could be improved, helping users to understand the process and apply corrective actions. One step in the direction of improved predictability is the identification of the Limiter block associated with the KUKA robot controllers that limit the acceleration and jerk obtained during motions. This work aims to provide dynamically feasible trajectories with reduced performance deterioration. Specifically, the Limiter's behaviour was analyzed and later predicted in a iterative manner, aiming for the maximum velocity, acceleration and jerk that can be achieved, starting from the current robot state and given specific robot information. Using the predicted bounds, the trajectory generator will determine the maximum achievable point that fulfills all the constraints, running an optimization problem in an iterative fashion. Nonetheless, the practical experiments represent a significant component allowing data collection and results validation.Mechanical Engineering | Systems and Contro
