  1. 1. Shape depiction using Local Light Alignment : Evaluating the shape enhancement capabilities of the Local Light Alignment technique at multiple scales

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Edvard Ahlsén; [2023]
    Nyckelord :Shape depiction; Non-photorealistic rendering; Shading; Multiple scales; Formskildring; ickerealistisk rendering; skuggning; skalrymdsmetoder;

    Sammanfattning : Local Light Alignment is a new shading based technique in the field of shape depiction, a field which concerns itself with techniques to represent and enhance the three-dimensional (3D) shape of objects in two-dimensional (2D) visual media. The main idea of Local Light Alignment is to locally adjust the incoming direction of light to create contrast in a way that enhances the perception of shape and surface detail. LÄS MER

  2. 2. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Eduardo Salvador Lopez; [2023]
    Nyckelord :Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

    Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER

  3. 3. Comprehensive Venus boundaries model : Empirical dependency of boundaries on the upstream conditions

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Umberto Rollero; [2023]
    Nyckelord :Bow shock; Ion Composition Boundary; Venus; Upstream conditions; Solar wind.; Bow shock; Bogshock; Ion Composition Boundary; Venus; Uppströmsförhållanden; Solvind.;

    Sammanfattning : Since Venus is an unmagnetized planet, it doesn’t interact with the solar wind in the same way as planets with an intrinsic magnetic field do. Due to its conductive ionosphere, however, it still possesses an induced magnetosphere. LÄS MER

  4. 4. An input-sample method for zonotopic obstacle avoidance with discrete-time control barrier functions

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xiong Xiong; [2022]
    Nyckelord :Control barrier functions; RRT; Discrete-time Control barrier function; Input sample; Kontrollbarriärfunktion; RRT; diskret tid Kontrollbarriärfunktion; inmatningsprov;

    Sammanfattning : In this thesis, we consider the motion planning problem for an autonomous vehicle in an obstacle-cluttered environment approximated by zonotopes, and we propose an input sampling algorithm leveraging discrete-time control barrier function conditions (DCBF). Specifically, an optimization-based control barrier function that takes into account the geometric shapes of the vehicle and obstacles is constructed and verified. LÄS MER

  5. 5. Compression Characteristics of Elastomer Elements

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rahul Nagaraj Dixit; [2021]
    Nyckelord :Continuum mechanics; Hyperelasticity; Mooney Rivlin; Rack and Pinion; Kontinuummekanik; Hyperelasticitet; Mooney Rivlin; Kuggstångsväxel;

    Sammanfattning : Compression of elastomer elements are nonlinear due to the cross-linked molecular structure owing to a property known as hyperelasticity. Hyperelasticity is defined as the nonlinear stress-strain behavior shown by rubber like materials which can be strained up to a range of 700% in tension and up to 40% in compression. LÄS MER
