  1. 1. An Empirical Study on the Generation of Linear Regions in ReLU Networks : Exploring the Relationship Between Data Topology and Network Complexity in Discriminative Modeling

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

    Author : Petter Eriksson; [2022]
    Keywords : Neural networks; Linear regions; Activation patterns; Piecewise linear activation functions; Data; Curvature; Neurala nätverk; Linjära regioner; Styckvis linjära aktiveringsfunktioner; Data; Krökning;

    Abstract : The far-reaching successes of deep neural networks in a wide variety of learning tasks have prompted research on how model properties account for high network performance. For a specific class of models whose activation functions are piecewise linear, one such property of interest is the number of linear regions that the network generates. READ MORE

  3. 2. Crack growth based FEM with embedded discontinuities

    University essay from KTH/Hållfasthetslära

    Author : David Lindblom; [2021]
    Keywords : PUFEM; Fracture Mechanics; J2-plasticity; FEAP; Strong discontinuity; Variational formulation; XFEM; PUFEM; Brottmekanik; J2-plasticitet; FEAP; Diskontinuitet; variationskalkyl;

    Abstract : In recent years there have been a major developments in the computational mechanics community when it comes to modelling of fracture mechanics. There are now several well established numerical methods that are implemented in commercial programs such as: Phase Field Modelling, Enhanced Assumed Strain (EAS), Smeared Crack Methods, Extended Finite Element Method (XFEM) and Partition of Unity Finite Element Method (PUFEM).

  4. 3. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

    University essay from KTH/Bro- och stålbyggnad

    Author : Markus Hansell; Panagiotis Tamtakos; [2020]
    Keywords : Hollow core slab; Structural dynamics; Signal analysis; Mode shape; Frequency response function; Complex mode; FE-model; Håldäcksbjälklag; Strukturdynamik; Signalanalys; Modform; Frekvenssvar; Komplex mod; FE-modellering.;

    Abstract : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. READ MORE

  5. 4. Quality Assessment of Thin Polymer Components using NonDestructive Testing : Degree Project for Master of Science in Mechanical Engineering with emphasis on Applied Mechanics

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Markus Nilsson; Tom Carlén; [2019]
    Keywords : nondestructive testing; polymer; nonlinear acoustics; instant dynamics amplitude recovery.; oförstörande provning; polymer; olinjär akustik; instant dynamics amplitude recovery;

    Abstract : Polymer components are used in many different applications, including in industries where critical applications put high requirements regarding quality assessment. Such applications might include medical or food where the presence of discontinuities might induce bacterial growth or other unpleasantries, thus certain manufacturers must be able to maintain a zero-tolerance towards damaged components.

  6. 5. Efficient Barrier Option Greeks using Automatic Differentation

    University essay from Lunds universitet/Matematisk statistik

    Author : Gustav Hedin; [2019]
    Keywords : Automatic Differentiation; Greeks; Barrier Option; Vibrato Monte Carlo; Mathematics and Statistics;

    Abstract : Automatic Differentiation (AD) is an effective method for calculation of derivatives. It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. READ MORE
