  1. 21. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Måns Boll; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  3. 22. Speckles in Coherent LiDAR

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ivar Nyman; [2022]
    Keywords : Spckle; LiDAR; coherent;

    Abstract : Speckles are a phenomenon which often appears in situations involving lasers. Their properties can be used as an advantage but in the case of LiDAR applications, they’re purelydestructive. The peaks and troughs of the intensity distribution across the collimatinglens can be seen as variations in signal strength at the detector. READ MORE

  4. 23. Simple RSRP Fingerprint Collection Setup and Indoor Positioning in 5G

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sofi Flink; Annie Tallund; [2022]
    Keywords : 5G; indoor positioning; radio fingerprint; k nearest neighbor; naive bayes; automated data collection; Technology and Engineering;

    Abstract : Solving for a way to accurately predict the position of a user equipment is crucial in an array of applications within 5G new radio. One approach is to form unique identifiers, also known as fingerprints, and map them to positional data in an area. READ MORE

  5. 24. Quantification of Fatty Acid Composition in Short T2* Tissue Using MRI – Comparison of 3 T and 7 T

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Felix Månsson; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: To optimize a method and develop an algorithm to quantify Fatty Acid Composition (FAC) in bone marrow adipose tissue. By using different reconstruction models, compare different MRI systems (3 T and 7 T) to find the optimal field strength and reconstruction model for FAC quantification. READ MORE

  6. 25. Autonomous UAV Path Planning using RSS signals in Search and Rescue Operations

    University essay from Linköpings universitet/Reglerteknik

    Author : Axel Anhammer; Hugo Lundeberg; [2022]
    Keywords : UAV; DQN; Deep Q Network; particle filter; point mass filter; MDP; POMDP; Markov decision process; partially observable Markov decision process;

    Abstract : Unmanned aerial vehicles (UAVs) have emerged as a promising technology in search and rescue operations (SAR). UAVs have the ability to provide more timely localization, thus decreasing the crucial duration of SAR operations. READ MORE
