   Abstract : Epilepsy affects more than 50 million people and is one of the most prevalent neurological disorders and has a high impact on the quality of life of those suffering from it. However, 70% of epilepsy patients can live seizure free with proper diagnosis and treatment. Patients are evaluated using scalp EEG recordings which is cheap and non-invasive. READ MORE

3. 2. Automatic control of renewable energy sources at varying load

   University essay from Uppsala universitet/Elektricitetslära

   Author : Patrik Zenkert; Douglas Lowén; [2020]
   Keywords : Automatic control; SCADA; Renewable energy;

   Abstract : With the current climate crisis with the global temperature increasing due to fossil fuels being used there are big investments in green energy. Wind power is a good alternative to fossil fueled power and already has a widespread use. READ MORE

4. 3. Testing and analysis of an intelligent electronic device (IED) prototype for MTDC overhead line application

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

   Author : Ashen Gomes; [2020]
   Keywords : ;

   Abstract : A key problem faced with the implementation of a multi-terminal direct current (MTDC) grid is fault mitigation. One method extensively researched in mitigating a fault in MTDC is to use protection intelligent electronic devices (IEDs) and fast direct current circuit breakers (DCCBs). READ MORE

5. 4. Filter Design for an HVDC protection IED

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

   Author : Evgeny Genov; [2020]
   Keywords : ;

   Abstract : A selective fault detection approach is necessary for successful implementation of multi-terminal high-voltage direct-current (HVDC) grids. Fault detection is per- formed by an intelligent electronic device (IED) that takes in voltage and current measurements, performs fault detection algorithms, and outputs, e.g. READ MORE

6. 5. Evaluation of New Features for Extractive Summarization of Meeting Transcripts : Improvement of meeting summarization based on functional segmentation, introducing topic model, named entities and domain specific frequency measure

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

   Author : Emilio Marinone; [2019]
   Keywords : ;

   Abstract : Automatic summarization of meeting transcripts has been widely stud­ied in last two decades, achieving continuous improvements in terms of the standard summarization metric (ROUGE). A user study has shown that people noticeably prefer abstractive summarization rather than the extractive approach. READ MORE
