21. Implementation and Evaluation of Uncertainty Estimation for Advanced Pharmacokinetic Models in DCE-MRI
University essay from Umeå universitet/Institutionen för fysikAbstract : The goal of this report is to develop code in Python that implements and evaluates a multivariate linear error propagation for commonly used DCE-MRI models. Two pharmoacokinetic models (PK-models) were tested; modified Kety model and two-compartment exchange model. READ MORE

22. Extraction of Loudspeaker- and room impulse responses under overlapping conditions
University essay from Uppsala universitet/Signaler och systemAbstract : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

23. Indoor 5G Positioning using Multipath Measurements
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : Positioning with high precision and reliability is considered as an important feature of new wireless radio networks such as 5G. In areas where satellite positioning is not available or is not reliable enough, 5G can work as an alternative. An example is inside factories where autonomous vehicles might need to be positioned in complex environments. READ MORE

25. Design and Verification of An Energy-Efficient Edge-Pursuit Comparator
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : With the rapid development of mobile communication, sensors, and biomedical in recent years, the demand for accurate data information, highquality audio and image has become much more significant, which requires a high-precision Analog to Digital Converter (ADC) to process weak analog signals. As one of the core modules of ADC, the comparator’s precision, speed, stability, and noise play a key role in the performance of the whole circuit. READ MORE
