16. Development of Stockham Fast Fourier Transform using Data-Centric Parallel Programming
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Writing efficient scientific applications for modern High Performance Computing (HPC) systems has become much harder during the last years due to the rise of heterogeneous computer architectures. The inclusion of hardware accelerators has caused an increase in the number of required technologies to reach high performance, a change that has programming these systems outside the skill-set of a domain scientist.

17. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

18. FFT Implemention on FPGA for 5G Networks
University essay from Linköpings universitet/DatorteknikAbstract : The main goal of this thesis will be the design and implementation of a 2048-point FFT on an FPGA through the use of VHDL code.The FFT will use a butterfly Radix-2 architecture with focus on the comparison of the parameters between the system with different Worlengths, Coefficient Wordlengths and Symbol Error rates as well as different modulation types, comparing 64QAM and 256QAM for the 5Gsystem.

19. Efficient Energy Use of FPGA for Underwater Sensor Network
University essay from Linköpings universitet/Elektroniska Kretsar och SystemAbstract : Operational time is becoming an increasingly important aspect in electronic devices and is also highly relevant in Underwater Acoustic Sensor Networks (UWSN). This thesis contains a study which explores what can be done to de-crease power consumption while maintaining the same functionality of an FPGA inside an underwater sensor-node network. READ MORE

20. Minimising Memory Access Conflicts for FFT on a DSP
University essay from Linköpings universitet/DatorteknikAbstract : The FFT support in an Ericsson's proprietary DSP is to be improved in order to achieve high performance without disrupting the current DSP architecture too much. The FFT:s and inverse FFT:s in question should support FFT sizes ranging from 12-2048, where the size is a multiple of prime factors 2, 3 and 5. READ MORE
