1. 1. Learning the shapes of protein pockets

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

   Author : Alejandro Corrochano; Yossra Gharbi; [2022-10-14]
   Keywords : Protein; cavity; ligand-binding; 3D-equivariance; shape; latent space; e3nn; Fpocket; sc-PDB;

   Abstract : The comparison of protein pockets plays an important role in drug discovery. Through the identification of binding sites with similar structures, we can assist in finding hits and characterizing the function of proteins. Traditionally, the geometry of cavities has been described with scalar features, which are not fully representative of the shape. READ MORE

3. 2. Wire and Arc Additive Manufacturing : Topology Optimised Vehicle Component

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Malte Petersson; [2022]
   Keywords : Wire and Arc Additive Manufacturing; Additive Manufacturing; WAAM; AM; Overhang; Cooling times; Simulation; Welding;

   Abstract : Wire and arc additive manufacturing (WAAM) is a manufacturing method using a numerical controlled motion system and a welding system to additively manufacture three dimensional components. The motion system is programmed from three dimensional computer aided design model data (3D-CAD) of the intended geometry which is then sliced in to layers and welded on additively. READ MORE

4. 3. Fatigue Life Prediction of a Topology-Optimised Polyamide-12 Part Manufactured with Multi-Jet Fusion Technology

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

5. 4. AI-based Quality Inspection forShort-Series Production : Using synthetic dataset to perform instance segmentation forquality inspection

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Simon Tsehaie Russom; [2022]
   Keywords : Synthetic Training Dataset; Geometrical Defect Detection; Instance Segmentation; Data Augmentation Techniques; Mask R-CNN; Transformers; Syntetisk Träningsdataset; Detektion av Geometriska Defekter; Instanssegmentering; Tekniker för Dataaugmentering; Mask R-CNN; Transformers;

   Abstract : Quality inspection is an essential part of almost any industrial production line. However, designing customized solutions for defect detection for every product can be costlyfor the production line. This is especially the case for short-series production, where theproduction time is limited. READ MORE

6. 5. Implementation of thermomechanical laser welding simulation : Predicting displacements of fusing A AISI304 T-JOINT

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Anton Rolseth; Anton Gustafsson; [2021]
   Keywords : Laser welding; Finite element method; ABAQUS; Thermomechanical simulation; Heat source models; DFLUX; Element activation;

   Abstract : Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. READ MORE
