  1. 36. Investigation of Aerosol Influence on Operational Weather Forecasts

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Nellie Edvardsson; [2016]
    Keywords : Sea salt aerosols; aerosols; numerical weather prediction; NWP; HARMONIE; weather forecasts; Physics and Astronomy;

    Abstract : Low precipitation events are difficult to predict due to the many processes taking part in formation of precipitation. An additional challenge is that many of the processes act on a smaller scale than what weather models can resolve. The aerosol impact on the state of the atmosphere is an example of one of these processes. READ MORE

  3. 37. Antenna Study for IoT Devices

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Author : Rickard Hedlund; [2016]
    Keywords : Antenna; patch; inverted-F; meandered inverted-F;

    Abstract : This thesis investigates the possibility to design printed circuit board (PCB) antennas with a maximum area size of 30 x 30 mm^2 at 2.4 GHz. The resulting antenna parameters are compared to those of a commercial, more costly chip antenna, i.e. READ MORE

  4. 38. Assessment of Shear Wave Elastography Acoustic Output - a Simulation and Experimental Study

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Cristiana Golfetto; [2016]
    Keywords : Technology;

    Abstract : Shear Wave Elastography (SWE) is a medical imaging modality which is able to measure tissue stiffness through the speed of ultrasound-induced shear waves. Pre- vious studies have reviewed the safety aspects of clinical ultrasound, highlighting the harmlessness of the technique. READ MORE

  5. 39. Miniaturized quadrature hybrid and rat race coupler utilizing coupled lines for LTE frequency bands

    University essay from Fysik och elektroteknik; Tekniska högskolan

    Author : Masiur Rahman; [2013]
    Keywords : Coupler; quadrature hybrid coupler; rat race coupler; LTE frequecy band; miniaturization; coupled line; microwave communication etc.;

    Abstract : Nowadays, demands for fully integrated and miniaturized RFIC (Radio Frequency Integrated Circuits) have increased in wireless microwave communication system. Passive components such as coupler, divider and filters are always fabricated in outside of ICs due to their bulky sizes, which have been a great barrier to a realization of a fully integrated design.

  6. 40. Comparison of Pushing Sequences for Shear Wave Elastography

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Tim Nordenfur; [2013]
    Keywords : shear wave elastography; ultrasound imaging; pushing sequences; plane wave imaging;

    Abstract : Shear wave elastography is a medical imaging modality in which tissue elasticity is estimated by measuring the speed of ultrasound-induced shear waves. This study aimed to implement four shear wave generating pushes and compare their performance according to chosen metrics. READ MORE
