   Sammanfattning : Cyber-Physical System (CPS) or Digital-Twin approach are becoming popular in industry 4.0 revolution. CPS not only allow to view the online status of equipment, but also allow to predict the health of tool. LÄS MER

3. 17. Digital signalbehandling i realtid; en jämförelse mellan CPU och GPU : Brusfiltrering av ljudsignal med hjälp av FFT

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ludwig Emilsson; [2020]
   Nyckelord :;

   Sammanfattning : Over the past 40 years, music production has evolved from being an analog process to a digital one. Analog instruments and filtering of signals have been complimented and partially replaced by digital instruments and filters in the form of software. LÄS MER

4. 18. Development of Stockham Fast Fourier Transform using Data-Centric Parallel Programming

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Gabriel Bengtsson; [2020]
   Nyckelord :;

   Sammanfattning : 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.

5. 19. Image Enhancement & Automatic Detection of Exudates in Diabetic Retinopathy

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Författare :Vivek Mallampati; [2019]
   Nyckelord :Exudates; Diabetic Retinopathy; Mahalanobis Distance; Histogram Equalization; Contrast Limited Adaptive Histogram Equalization.;

   Sammanfattning : Diabetic retinopathy (DR) is becoming a global health concern, which causes the loss of vision of most patients with the disease. Due to the vast prevalence of the disease, the automated detection of the DR is needed for quick diagnoses where the progress of the disease is monitored by detection of exudates changes and their classifications in the fundus retina images.

7. 20. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

   Författare :Richard Hedlund; [2019]
   Nyckelord :Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

   Sammanfattning : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.
