1. 1. Design of high performance buildings : Vulnerability of buildings to climate change from an energy perspective

   Master-uppsats, KTH/Hållbara byggnader

   Författare :Robin Gobert; [2022]
   Nyckelord :Climate Change; High Performance Buildings; Dynamic Thermal Simulations; Thermal Regulation; Environmental Regulation; Cooling Needs; Heating Needs; Representative Data; Big Data; Clustering;

   Sammanfattning : The challenge of climate change is twofold: to mitigate (prevent) the causes of climate change and to prepare (adapt) to the inevitable effects and consequences. Building and construction are key sectors for decarbonisation (mitigation). LÄS MER

3. 2. Automatic Annotation of Speech: Exploring Boundaries within Forced Alignment for Swedish and Norwegian

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Klaudia Biczysko; [2022]
   Nyckelord :forced alignment; automatic speech recognition; ASR; natural language processing; under-resourced languages; Swedish; Norwegian; CTC segmentation; wav2vec2; kaldi; HTK; dynamic time warping;

   Sammanfattning : In Automatic Speech Recognition, there is an extensive need for time-aligned data. Manual speech segmentation has been shown to be more laborious than manual transcription, especially when dealing with tens of hours of speech. LÄS MER

4. 3. Real Time Lidar and ICP-Based Odometry in Dynamic Environments

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Carl Hampus Hedén; Ludvig Hansson Granström; [2022]
   Nyckelord :ICP; Localization;

   Sammanfattning : A robust and highly accurate positioning system is required to transition to fully autonomous vehicles in society.  This thesis investigates the potential for lidar sensors to be a part of a localization system, adding redundancy in case of an outage in a global navigation satellite system GNSS.

7. 5. Monte Carlo Optimization of Neuromorphic Cricket Auditory Feature Detection Circuits in the Dynap-SE Processor

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Mattias Nilsson; [2018]
   Nyckelord :Neuromorphic engineering; Spiking neural networks; Pattern recognition; Feature detection; Training protocol; Software tools;

   Sammanfattning : Neuromorphic information processing systems mimic the dynamics of neurons and synapses, and the architecture of biological nervous systems. By using a combination of sub-threshold analog circuits, and fast programmable digital circuits, spiking neural networks with co-localized memory and computation can be implemented, enabling more energy-efficient information processing than conventional von Neumann digital computers.
