  1. 1. Realism of Procedural Lichens on Horizontal Stone Surfaces : Simulation and evaluation of lichens

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

    Author : Anders Steen; [2022]
    Keywords : procedural generation; lichen; perceived realism; simulation;

    Abstract : Humans use creativity and manual dexterity to create things, usually in a labor-intensive process. Procedural content generation (PCG) is an approach where computers do most of the manual work of creating virtual objects, while a human leads the creative process. READ MORE

  3. 2. Simulating Low Frequency Reverberation in Rooms

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Mattias Svensson; [2020]
    Keywords : Low frequencies; Room acoustics; Finite Difference Time Domain method; FDTD.; Rumsakustik; låga frekvenser; Finite Difference Time Domain metoden; FDTD.;

    Abstract : The aim of this thesis was to make a practical tool for low frequency analysis in room acoustics.The need arises from Acad’s experience that their results from simulations using raytracing software deviate in the lower frequencies when compared to field measurements inrooms.

  4. 3. Sheet Metal Forming Simulations with Elastic Dies: Emphasis on Computational Cost

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Sara Allesson; [2019]
    Keywords : Elastic Sheet Metal Forming Simulation; Computational Cost; Decomposition; LS-DYNA; Elastisk plåtformningssimulering; beräkningskostnad; dekomposition; LS-DYNA;

    Abstract : The car industry produces many of their car parts by using sheet metal forming, where one of the most time-consuming phases is the development and manufacturing of new forming tools. As of today, when a new tool is to be evaluated in terms of usability, a forming simulation is conducted to predict possible failures before manufacturing. READ MORE

  5. 4. Technological measures needed for 100% renewable electricity system in Lithuania and feasibility of their future competitiveness

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

    Author : Justinas Jasiunas; [2018]
    Keywords : ;

    Abstract : This study aims to improve understanding the role of energy storage and other technologies in enablingeconomically competitive variable renewable energy based power systems which hold promise to minimiseenvironmental, energy security and other externalities of existing systems. The study focuses on insulatedLithuanian power system, which does not rely on other non-renewable systems to operate, 100% suppliedby renewables with at least 80% of that from solar and wind.

  6. 5. Accelerated Engine Suspension Load Prediction and Exhaust System Displacement Simulation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mo Bai; Sagar Parampalli Mahabaleshwar; [2017]
    Keywords : ADAMS Car; Simulation time; RLD; Displacement; MSC ADAMS Car; simuleringstid; RLD; deformationer;

    Abstract : In today’s competitive automotive industry, most companies are trying to make their new designs and features implemented in their products to be ahead of their competitors. However, in the preliminary design stage of CEVT vehicles, dynamic simulation consumes excessive amount of time depending on the complexity of the dynamic model and simulation settings. READ MORE
