    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. 2. TRIANGEL TORGET

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Tamas Halasz; [2023]
    Nyckelord :triangel square; triangel torget; folkets hus; trä; limträ; Nynäshamn;

    Sammanfattning : Folketshus och en plats för de lokala producenterna att sälja de lokala produkterna i hjärtat av Nynäshamn. Jag valde denna plats för att den av många uppfattas som osäker och mörk. Genom att skapa en mer levande och användbar miljö kan den outnyttjade grusplanen få nytt liv och bli en tillgång för hela samhället. LÄS MER

  4. 3. Straight to the Heart : Classification of Multi-Channel ECG-signals using MiniROCKET

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

    Nyckelord :MiniROCKET; Time-series analysis; Multi-variate; Classification; Convolutional Neural Network; MiniROCKET; Tidsserieanalys; Multivariat; Klassifikation; Convolutional Neural Network;

    Sammanfattning : Machine Learning (ML) has revolutionized various domains, with biomedicine standing out as a major beneficiary. In the realm of biomedicine, Convolutional Neural Networks (CNNs) have notably played a pivotal role since their inception, particularly in applications such as time-series classification. LÄS MER

  5. 4. Automatic 3D Segmentation in CT images of Congenital Heart Defects using Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Matilda Dahlström; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 3D segmentations of hearts with congenital heart defects are routinely used today. They are used to study hearts and to prepare before surgery which makes them an important part of patient care. The 3D segmentations are usually created manually, which is a time-consuming process.

  7. 5. Organic waste streams in the wine industry

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Hanna Eriksson; [2022]
    Nyckelord :wine; waste; utilization; grapes; residue; pomace;

    Sammanfattning : Today, the annual global production of grapes surpasses seventy million tonnes. Of the grapes used toward winemaking, one fourth end up as pomace. In addition to pomace, vine pruning residues, stems and wastewater sludge contribute to the immense volumes of waste that for a long time has been considered as without value. LÄS MER
