1. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

2. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. READ MORE

5. Analysing the Effect of Working Memory Training on Brain Networks Using MEG and Neuroimaging
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Introduction: The brain can change its structure and functionality as a result ofexternal factors. The working memory (WM) of the brain is where informationcan be held and manipulated during a short period of time, with the purpose ofachieving higher cognitive functions such as reasoning and learning.
