  1. 1. Influence of grain growth on the thermal structure of inner protoplanetary discs

    University essay from Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Sofia Savvidou; [2018]
    Keywords : protoplanetary disc; thermal structure; hydrodynamical simulations; grain size distribution; grain growth; opacity; iceline; Physics and Astronomy;

    Abstract : Protoplanetary discs surround young stars for the first few million years after their formation and they are the birthplaces of planetary systems. The thermal structure of the discs is regulated by their dust content and the opacity that it provides. READ MORE

  2. 2. Evaluating LoRaWAN for IoT applications by developing a wireless parking space monitoring sensor

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Felix Jontegen; Emma Good; [2018]
    Keywords : LoRaWAN; IoT; Parking space monitoring; Car detection; The Things Network; LoRaWAN; IoT; Parkeringsplatsbevakare; Bildetektering; The Things Network;

    Abstract : The process of finding a parking space can be a tedious task that drivers spent too much time on today. With the rising threat from global warming, reducing the time spent driving is vital. READ MORE

  3. 3. Distance Attenuation of Tram Noise in Open Urban Areas

    University essay from Chalmers tekniska högskola/Institutionen för arkitektur och samhällsbyggnadsteknik

    Author : Emil Regnström; Mattias Willig; [2018]
    Keywords : Trams; sound; distance attenuation; point source; line source; sound pressure level; sound power level; sound spectrum; Oslo; Gothenburg;

    Abstract : The aim of this work was to investigate how the rate of the sound attenuation from a tram changes over distance in an open city environment, and to get a better general understanding of the tram as a sound source. By setting up an array of microphones with an internal distance of approximately 8 meters, perpendicular to the tram tracks, measurements were carried out at three different locations in Oslo as well as two in Gothenburg, and the sound attenuation was analyzed for a total of five different tram types.

  4. 4. Systemutformning av autonom batteridriven traktor inom lantbruket

    University essay from SLU/Dept. of Energy and Technology

    Author : Martin Ericson; [2018]
    Keywords : systemutformning; batteridrift; framtidens lantbruk;

    Abstract : In this study, data from different studies were used to find how much energy that a conventional tractor required per hectare when it was performing different operations on a field. Data for operation speed and power demand were taken from an earlier study for each task of the tractor model Valtra 6600. READ MORE

  5. 5. Implementation of Visible Light communications For Indoor Applications

    University essay from Blekinge Tekniska Högskola

    Author : Nitish Nagabhairava; [2018]
    Keywords : OOK modulation scheme; MATLAB-Simulation; Light Emitting Diodes .;

    Abstract : In recent years there is growing research in optical wireless communication. This growing popularity isdue to several characteristics like such as large bandwidth that is also not having spectrum regulationsimposed, low cost and license-free operation. READ MORE
