1. 21. Super-Resolution for Fast Multi-Contrast Magnetic Resonance Imaging

   University essay from Umeå universitet/Institutionen för fysik

   Author : Erik Nilsson; [2019]
   Keywords : Deep learning; convolutional neural networks; CNN; super-resolution; MRI;

   Abstract : There are many clinical situations where magnetic resonance imaging (MRI) is preferable over other imaging modalities, while the major disadvantage is the relatively long scan time. Due to limited resources, this means that not all patients can be offered an MRI scan, even though it could provide crucial information. READ MORE

3. 22. Low-dispersive Leaky-wave Antennas: A Viable Approach for Fifth Generation (5G) mmWave Base Station Antennas

   University essay from KTH/Elektroteknisk teori och konstruktion

   Author : Oskar Dahlberg; [2019]
   Keywords : ;

   Abstract : In this work, a method to achieve reduced beam-squint in fully metallic leaky-wave antennas is proposed and its applicability for high frequency, high gain, base station antennas in future communication networks is indicated. The antenna is built in gap waveguide technology, where the fundamental mode is allowed to leak by removal of one of the waveguide walls. READ MORE

4. 23. Resource Efficient Representation of Machine Learning Models : investigating optimization options for decision trees in embedded systems

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Jacob Lundberg; [2019]
   Keywords : machine learning; rule fit; decision trees; embedded systems; resources; ensemble methods; lasso; regression; optimization;

   Abstract : Combining embedded systems and machine learning models is an exciting prospect. However, to fully target any embedded system, with the most stringent resource requirements, the models have to be designed with care not to overwhelm it. Decision tree ensembles are targeted in this thesis. READ MORE

5. 24. Modeling and Characterization of a Propagation Channel in a Body-Centric Nano-Network

   University essay from Umeå universitet/Institutionen för fysik

   Author : Charlie Pettersson; [2018]
   Keywords : ;

   Abstract : Researchers have been trying to find smart health solutions that will allow people to continuously monitor their health through applications connected to the internet. One possible solution involve using nano-machines to create body-centric networks. READ MORE

6. 25. GENERAL WAKE-UP RADIO MODULE FOR ISM BAND

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Mohammed Ashiq Rahman Tajudeen; [2018]
   Keywords : ;

   Abstract : With the word of smart, the whole world is running on the smart technologies and smart devices which are fairly constructed by wireless sensors networks. The heart of the WSNs are nodes, which are deployed in different environmental conditions with different applications. READ MORE
