  1. 16. Synthesizing of brain MRE wave data

    University essay from KTH/Medicinsk avbildning

    Author : Maryia Yuliuhina; [2023]
    Keywords : MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

    Abstract : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. READ MORE

  3. 17. Harmonic Filters For Electronic Drive Systems Targeting Aircraft Applications

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Emelie Berglund; [2023]
    Keywords : Active Cancellation Filter; BLDC;

    Abstract : Climate change pressures fossil-driven vehicles into electrification to sustain a healthy planet and environment for its inhabitants. Air traffic contributes to the ongoing climate crisis, and electric aircraft is taking its toll on the avionics market. READ MORE

  4. 18. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eriksson Janze Oscar; [2023]
    Keywords : DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

    Abstract : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. READ MORE

  5. 19. Automatic Maximum Sound Pressure Level (SPL) Measurements Inside Cars

    Author : Luyao Dong; [2023]
    Keywords : Audio Measurement; Distortions; Maximum Sound Pressure Level SPL ; Automotive Audio; Ljudmätning; distorsion; maximal ljudtrycksnivå; billjud;

    Abstract : With a growing interest in technical specifications among consumers, there is a need for accessible measurement tools that enable individuals to evaluate the performance of their equipment, including common speakers and car audio systems, beyond what the manufacturer provides. However, the existing measurement systems are often geared towards professionals. READ MORE

  6. 20. Modulation of the optical properties of quantum dots by surface acoustic waves

    University essay from KTH/Tillämpad fysik

    Author : Tanguy Schetelat; [2023]
    Keywords : Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

    Abstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE
