  1. 1. Deep Learning with Importance Sampling for Brain Tumor MR Segmentation

    University essay from KTH/Optimeringslära och systemteori

    Author : Hanna Westermark; [2021]
    Keywords : Deep learning; importance sampling; segmentation; convolutional neural networks; MRI; brain tumour; Djupinlärning; importance sampling; segmentering; faltningsnätverk; MRI; hjärntumör;

    Abstract : Segmentation of magnetic resonance images is an important part of planning radiotherapy treat-ments for patients with brain tumours but due to the number of images contained within a scan and the level of detail required, manual segmentation is a time consuming task. Convolutional neural networks have been proposed as tools for automated segmentation and shown promising results. READ MORE

  2. 2. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    University essay from KTH/Ytbehandlingsteknik

    Author : Mohamed Hassan Abdi; [2021]
    Keywords : Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Abstract : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. READ MORE

  3. 3. Ensembles of Single Image Super-Resolution Generative Adversarial Networks

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

    Author : Victor Castillo Araújo; [2021]
    Keywords : Generative Adversarial Networks; Single Image Super-Resolution; Computer Vision; Convolutional Neural Networks; Ensemble Learning; Generative Adversarial Networks; Superupplösning; Datorseende; Bildanalys; Convolutional neural networks; Ensembler;

    Abstract : Generative Adversarial Networks have been used to obtain state-of-the-art results for low-level computer vision tasks like single image super-resolution, however, they are notoriously difficult to train due to the instability related to the competing minimax framework. Additionally, traditional ensembling mechanisms cannot be effectively applied with these types of networks due to the resources they require at inference time and the complexity of their architectures.

  4. 4. Deep Reinforcement Learning for Autonomous Highway Driving Scenario

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

    Author : Neil Pradhan; [2021]
    Keywords : Deep reinforcement learning; Highway driving scenario; Tactical decision making; fuel reduction; high-level decision making; autonomous driving; Partially Observable Markov Decision Process POMDP .; Lärande om djupförstärkning; motorvägsscenario; taktiskt beslutsfattande; bränslereduktion; beslut på hög nivå; autonom körning; Partially Observable Markov Decision Process POMDP ;

    Abstract : We present an autonomous driving agent on a simulated highway driving scenario with vehicles such as cars and trucks moving with stochastically variable velocity profiles. The focus of the simulated environment is to test tactical decision making in highway driving scenarios. READ MORE

  5. 5. Whole-Cell Patch Clamp Investigations on Rapid Synaptic Scaling of Mouse CA1 Pyramidal Neurons under Optogenetic Stimulation

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Teoretisk kemi

    Author : Leonard Groth; [2021]
    Keywords : Patch clamp; Electrophysiology; Optogenetics; Epilepsy; Voltage clamp; Current clamp; Neuroscience; Applied Biochemistry; Tillämpad biokemi; Technology and Engineering;

    Abstract : The brain consists of billions of neurons forming intricate contiguous networks. The connective strength in these networks change throughout life in response to experience and environmental stimuli. READ MORE
