  1. 1. Minimization of Model-based Tests in Modbat

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Caroline Borg; [2023]
    Keywords : Software testing; Model-based testing; Test minimization; Delta debugging; Modbat; modmin; Mjukvarutestning; Modellbaserad testning; Testminimering; Delta debugging; Modbat; modmin;

    Abstract : Model-based testing (MBT) is a promising testing method with advantages like exhaustive exploration and high maintainability. However, one notable downside is that the generated tests usually contain much unnecessary noise. READ MORE

  3. 2. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

    University essay from KTH/Bro- och stålbyggnad

    Author : Zakariya Benosmane; [2022]
    Keywords : Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

    Abstract : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. READ MORE

  4. 3. Approximating the element matrices in an unfitted finite element method using neural networks

    University essay from Umeå universitet/Institutionen för fysik

    Author : Amanda Bertgren; [2022]
    Keywords : Finite element method; CutFEM; neural networks; machine learning;

    Abstract : This study investigates the possibility of combining an unfitted finite element method, CutFEM, with neural networks, in an attempt to reduce the computational time on evolving domains. Finite element methods are used to solve partial differential equations by fitting a spatial and temporal discretisation to the momentous domain. READ MORE

  5. 4. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

    University essay from KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

    Author : Zeinab Mirzahassanagha; Eva Malo; [2021]
    Keywords : CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

    Abstract : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. READ MORE

  6. 5. Strength Analysis of Deployable Hangar

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Manan Sureshbhai Rudani; Hampus Ring; [2021]
    Keywords : Strength analysis; Hangar; Finite Element Method; Eurocodes; Snow load; Wind load; Ultimate Limit States;

    Abstract : It is of interest to investigate extended usability of Saab’s Deployable Aircraft Maintenance facility(DAM) with respect to Eurocode standards. One of the features of the deployable hangar is that it shouldcomply with the structural strength standards for permanent buildings which requires compliance withEurocodes. READ MORE
